1 Chapter 1 : List of roof shapes - Wikipedia The "Roof Construction Manual" with over plans and photographs is a vital reference work on the construction of pitched roofs. It offers extensive and fundamental information on all common types of roofing, and provides practical details for their construction. Coming to grips with the different types of pitched roofs out there can definitely be challenging, but when you get it right it can make your property look just the way that you had planned. There are various kinds of roofs that you can put in place but, for the most part, you will find that you will be working with two very specific kinds of pitched roof types: Truss roofs â These are very common too and they are made and delivered by using a specific factory truss that is sent out to you. Depending on what you go for you can get a totally different response from your roof, and the entire planning and preparation for putting the roof up in the first place will be totally changed. Rafter sizes tend to differ massively, and will normally be determined by finding out the length from the wall plate to the ridges, as well as the type of roof covering that is being used. Most people try and keep the cross section of any rafters as small as possible, as they can be very expensive to put together. Once the roof is actually put together, though, it would be foolish to try and change or modify it in any way, shape, or form. Make sure that you leave the roof just as it is come the end of construction if you want it to retain its original look and style. Truss Roofs Truss roofs, meanwhile, are made up using some factory-formed framing which will all combine together to make up the struts, rafters, and joist all in one piece. This makes it very easy for you to get the type of roof you want without any manual building being needed. Plate fastenings are used here as opposed to timber joints, which offer greater solidity and also ensure that the roof has that specific design to it. Trusses are designed to form part of the full structure, and should never be adjusted manually, as they arrive more or less ready to be put in place exactly as they are needed. Flat roofs â anything that falls under a 2: If you were to go to an architect or a roofing firm and mention that you wanted a flat, low, or steep slope, they would have a general idea of the kind of depth that you are looking for. What is it that needs to follow to make sure that it actually matches the pitch that you went for? Trying to explain pitched roof types can be a real pain, but the easiest way to think of them is: The kind of material that is used on the job will be determined by the slope, as some materials will not be able to be used because they may limit things like durability or drainage options, which will obviously be a bit of a problem moving forward. Likewise, they can make maintenance and construction far more challenging so it can help to work with specific materials to make them work for you. Typically, a roof will be split into one of the three categories mentioned above in terms of general sloping, whilst also making sure that it fits with the pitched roof style that we mentioned in the past. Managing a hip roof with two different pitches One thing that has become far more popular in recent years is the usage of hip roofs that have an alternative pitch at one side to the other. Whilst it may sound ridiculous today, they are used quite a lot these days to make a home look a bit more unique than others on the market. They have to be drawn in a plan view to make sure there is no bisecting of the angle of the walls, and to make sure that it can swing towards the steeper side of the roof. As you might imagine, jack rafters, framing, and purlins all need to be totally modified to fit with this shape of roof. Whatever you decide to go with, you can be assured that roofs of varied pitches and styles are very common across the board these days. Page 1

2 Chapter 2 : PITCHED ROOF CONSTRUCTION The Roof Construction Manual is a comprehensive reference work on the construction of pitched roofs, containing over plans and photographs. Roof shapes[ edit ] Flat: These are found in traditional buildings in regions with a low precipitation. Modern materials which are highly impermeable to water make possible the very large low-pitch roofs found on large commercial buildings. Although called flat they are generally gently pitched. Roof terrace including roof garden: Mono-pitched roofs Pitched here means a roof plane rather than a slope and implies it is not a flat roof Mono-pitched roof shed, skillion, lean-to roof [2]: A roof with one slope, historically attached to a taller wall. A roof comprising a mono-pitched roof or for larger buildings, series of, mono-pitched roofs with vertical surfaces glazed and pitched upward in general terms away from the equator, though other directions suit if direct sunlight is desired and where rooftop access may otherwise be impracticable. The roof tops are opaque, shielding traditionally workers and machinery from direct sunlight. This sort of roof commonly admits natural light into a factory, and is also known as "Northlight" in the northern hemisphere implying a single such plane. A roof appended, thus the name, to the wall of a building and by implication having further roofs or terraces above. See gallery below Multi-pitched roofs: Gable ridged, dual-pitched, peaked, saddle, pack-saddle, saddleback, [5] span roof [6]: A simple roof design shaped like an inverted V. The result of joining two or more gabled roof sections together, forming a T or L shape for the simplest forms, or any number of more complex shapes. See also roof pitch, crow-stepped, corbie stepped, stepped gable: A gable roof with its end parapet walls below extended slightly upwards and shaped to resemble steps. A-frame Half-hipped clipped gable: A combination of a gable and a hip roof pitched roof without changes to the walls with the hipped part at the top and the gable section lower down. A hybrid of hipped and gable with the gable wall at the top and hipped lower down; i. Overhanging eaves forming shelter around the building are a consequence where the gable wall is in line with the other walls of the buildings that is unless the upper gable or gables is or are recessed. A gable roof with one side longer than the other, and thus closer to the ground unless the pitch on one side is altered. A pitched extension of a main roof similar to a lean-to but an extension of the upper roof. A reversed gambrel or Mansard roof with the lower portion at a lower pitch than the upper portion. A V-shaped roof resembling an open book. A kink separates the roof into two parts running towards each other at an obtuse angle. A type of gable found in some traditional Japanese buildings. A type of Japanese roof construction. A hipped roof is sloped in two pairs of directions e. N-S and E-W compared to the one pair of direction e. N-S or E-W for a gable roof. A hybrid of a gable and a hipped roof. The reverse hybrid of a hipped and a gable roof. The result of joining two or more hip roof sections together, forming a T or L shape for the simplest forms, or any number of more complex shapes. A Swedish variant on the monitor roof; a double hip roof with a short vertical wall usually with small windows, popular from the 17th century on formal buildings. A roof with the pitch divided into a shallow slope above a steeper slope. The steep slope may be curved. An element of the Second Empire architectural style Mansard style in the U. A roof similar to a mansard but sloped in one direction rather than both. A roof with the shallow slope below the steeper slope at the eaves. Compare with bell roof. A Japanese decorative pent roof Pyramidal Pyramid roof pavilion roof: A hip roof on a square building. A multi-tiered and spired roof commonly found in Burmese royal and Buddhist architecture. A type of polygonal hipped roof with steeply pitched slopes rising to a peak Helm roof, Rhenish helm: A pyramidal roof with gable ends; often found on church towers. Twisted, an extreme display of craftsmanship found on some church towers in France, see gallery below. Arched roof Barrel, barrel-arched cradle, wagon: A round roof like a barrel tunnel vault. An arched roof in the form of a catenary curve. Historically also called a compass roof. Compare with bell-cast eaves. Page 2

3 Chapter 3 : A Guide To Roof Construction - Part 1 - Great Home Timber pitched rooftop construction details focus on the timber construction that is commonly used in most roofing constructions. Timber is a heavy material that adds strength to your roof, but comes at quite the cost. It can also prevent pest from entering. In these days of energy preservation, a roof can also contribute to preventing warmth being lost from a building. A great and strong roof ensures no trouble during rain and strong winds for the residents. A good roof requires maintenance like any other part of home. People spend much time and money with money to ensure that their roof is maintained properly. Roofs also come in different types and styles. In the United Kingdom two most popular types of roofs are: Flat roofs are usually made of variations of bitumen felt, and function as durable, long-lasting roofs that are perfect for water run-off in wet weather and protect wood and cement from potential build-ups of damp and dry rot. An architect makes the usual decision of the pitch. For example in the areas of high snowfall and rainfall, the roof pitch can be significantly longer as this will allow the snow to fall off the roof the roof. Most roofs that are above the liveable part of a household will be protected insulated to obey building regulations. In households, the protection which is also known as insulation is sometimes placed immediately above the ceiling. Preferably, it may be placed above the deck before it gets waterproofed. Roofs are designed differently for industrial, commercial, and domestic buildings. In some cases, insulations can also be positioned over the waterproof, but this sort of construction is normally confined to profitable and industrial buildings, and has seldom been used on domestic buildings. In almost all cases where RBM Reinforced Bituminous Membrane has been fitted, the exterior of the waterproof will need guard, both from infrared light and from an event like wildfire. The building regulations for new roofs laid down the degree of protection required in the case of a fire accident. Liquid material is applied, and single layer systems have this kind of protection built in. They at such, do not require additional protection. It is the most acceptable type of construction for domestic possessions and belongings, as it avoids the need for aeration of the roof construction. It is usually the most acceptable type of construction for domestic possessions and belongings as it avoids the need for aeration of the roof construction. The membrane is then attached to the insulation. Cold Roofs In the case of cold roofs, the residential flat roofs have the waterproof placed directly on the deck, and any insulation would be placed above the ceiling. In a cold weather, such roofs are inherently prone to condensation, which can cause material decay and deterioration. To decrease this danger, thorough aeration has to be provided to each and every space above the insulation, and this is often difficult to achieve. For example, if the roof borders the walls of a house, ventilation would not be achieved properly. Roof needs certain kinds of protection. Protection from rain and snow Protection from people Protection from sun and frost Protection from wind Protection from fire. With proper maintenance a correct roof can be constructed that will fulfil all the required standards. Hiring a professional is mandatory so that roof construction can be done in a proper way. Roofs require maintenance and regular checks. Some recommendations according to the weather of UK include: Limited entry unless the roof is intended for it. If occasional access is obligatory, e. Inspection twice a year: Try to do one inspection soon after rain, to see how well the water is draining away. With proper maintenance, a correct roof can be constructed that will fulfil all the required standards. Hiring a professional is mandatory, so that roof constructions can be done in a proper way.

4 Chapter 4 : Laying asphalt shingles on a roof pitch - Manual / blog.quintoapp.com Roof Construction Manual, English Edition [Eberhard Schunck, Hans Jochen Oster, Rainer Barthel, Kurt Kießl, Hans Jochen Oster, Kurt Kiebl] on blog.quintoapp.com *FREE* shipping on qualifying offers. The «Roof Construction Manual» is a comprehensive reference work on the construction of pitched roofs. A pitched roof is very angular in natural. When it comes to pitched rooftop construction, there are a few different options: In order to properly build this type of rooftop, you will need to begin with a detailed pitched roof construction diagram. This will give the exact pitched roof construction details to properly order supplies and correctly construct the roof. Among items found on this diagram include everything from ridge flashing location and how the roof will be framed. These instructions should be followed exactly in order to get the best results. Another aspect of construction to consider is a warm pitched roof construction. This is where you consider the ventilation and sealing of the roof. There are many benefits to this type of construction, including making a home more energy efficient and minimizing the thermal bridge at the eaves. After reading through the diagrams, you will want to first consider if you want to add a pitched roof dormer construction. A pitched roof dormer is generally a decorative piece that is added onto the roof to add a visually pleasing aspect to your roof. This can also be a functional piece to your home where you can walk into and even install a bench to sit on. This is all based on what is the personal preference that one is looking for in their home. Another consideration is the shape of the house and the intention for using this type of roof. Some roofing constructions offer additional living space, offering an often less expensive option than some other types of construction builds. As previously discussed, a good option is the warm pitched rooftop. The warm pitched rooftop details are all centered on insulation and ventilation. In this type of construction, the thermal insulation will be placed in the rafter line. There are some variables in the exact location of the insulation. It can be placed entirely above or partially between and above the rafter line. It can also be positioned between the rafters or partially between and below the rafter. Timber pitched rooftop construction details focus on the timber construction that is commonly used in most roofing constructions. Timber is a heavy material that adds strength to your roof, but comes at quite the cost. When constructing a pitched rooftop with timber, this can be an incredibly labor intensive build. It is important when doing this to have a properly detailed plan given to the carpenter because this type of construction is only as good as the carpenter. They will follow the calculations on the diagrams to make the right cuts and angles that are required for whichever type of pitched roof that is being built. There is a lot of care taken by the professionals with this type of roof construction because measurements must be perfect. This type of roof requires sloped roof construction as mansard rooftops have two slopes that are found on each of its sides as well as a lower slope. These types of roofs are very distinct from other pitched rooftops. These types of roofs can offer a lot of attic space and are a simple way to add more stories to a building. The upper level of this type of rooftop may not often be seen from afar, but upon closer look they can be more obvious. These are also very decorative options that feature dormer window surrounds that are often elaborate in nature. These are very common in Europe, especially in France where they were created as part of the construction of the Louvre. This is because these rooftops are a single sloping roof that is often not attached to other roof surfaces. These are also sometimes referred to as a pent roof or a lean-to. This can also be part of an addition to an existing roof where the main roof has a flat ceiling, but a mono-pitched part will slope to maximize the ceiling height. A lean-to pitched roof construction can be a very useful addition to any home because it can offer a great storage space similar to that of a shed. Here, items like firewood or lawn equipment can be stored safely. In order to plan this properly, a plan needs to be created based on the area and function of the space. If this space will be used for items like a lawnmower, it will need to be a larger space. If there is a lot of rain or snow, the slope will need to be steeper than in other locations to prevent the heavy moisture from pooling up and causing damage. The ground will need to be level to get a sturdy construction. These are all factors to consider when adding a lean-to rooftop area. A gabled roof is where there is an extension of the roof that is a triangular shape off of the end wall. The gable comes in a variety of different types which can depend on several factors, including structural system used as its base, Page 4

5 materials, climate, and for aesthetic purposes. The ends of the gables are wall bearing structures that add to the structural integrity. This may not be a good roofing choice in areas prone to hurricane or tornado prone locations because they can be easily torn off during very strong winds. A hipped roof is a roof that has its sides sloping downwards towards walls with a usually gentle slope. It is a roof slope that has no gable or any vertical sides to the roof. There are different shapes to this roof type. There is a square roof, which takes on the shape of a pyramid. There are also hip roofs that have two triangular sides and two sides shaped like a trapezoid. These are common roofing types that are found on bungalow and cottage homes. The construction of this type of roof is much more complicated than the simpler gable roof type. Although the actual roof is more complicated to construct, the walls that support it are easier to build since they are all level. This roof also comes with downsides. This type of roof can be more difficult to maintain because there is limited access in the attic. They are also more difficult to ventilate. A final downside to this roof type is that there is no way to put in a window like you can with a gable roof, meaning that there will be no natural light located in the attic. These are great roofing options for areas of extreme weather like tornadoes and hurricanes because they have fewer sharp corners that can act like wings and push up with the air. This is also because a hipped roof is a more structurally sound roof type due to its more complex construction. The shed roof is a simpler roof style where there is only one slope, which is common for additions like the lean-to roof type. This is more of a traditional manner in regards to cutting the timber while onsite and building up the roof by the use of rafters, ridge boards, joists and purlins among others. This can be determined by the size of the timbers or the size of the roof. In this method, there are joists and rafters. Joists are important because they prevent the outward spread of the rafters and also give important support to the ceiling below the area. Rafters are another important piece of this type of roof construction. These are nailed to a wall plate at the top of each supporting wall. Their length is determined by the length of the wall plate to the ridge. The rafters have triangular sections that are cut out of them in order to fit nicely on the wall plate. The top of the rafter will then be cut at an angle and nailed to the ridge board. Another section of this type of roof construction is purlins, as well as the associated struts. These are used in order to offer extra support for the rafters, adding strength to the roof. The purlins are found at right angles in respect to the rafters, and the associated struts are found every fourth rafter which attaches the joists to above a supporting wall. Then, there are hangers that are found at right angles to the joists, which help keep the ceiling held up. Collars are located further down the rafters and offer extra binding between rafters to help keep the roof strong. The truss is a more modern method of construction. These are each made with the exact position of the roof structure and are created by using butt jointed timber lengths that are nailed together using plate fastenings. These are usually bolted together, or they also are mortised and tenoned, and then pegged afterwards. They are designed to create part of the entire roof structure which is why they should not be altered in any way unless consulting an engineer to ensure that the structure is not compromised by these changes. This applied to any type of construction. The complexity of pitched rooftop construction relies on a variety of factors. First of all, there are many details to pitched roof types that can make construction more complex. There are ridges, eaves, hips, abutments, and the centerline of the ridge. Some roofs have some of these aspects, while other roofs may have all of these features. This all depends on the aesthetic design for the roof and the types of structures that are required to be a structurally sound roof. Ridges, hips and valleys are the corner or joint areas that are located where the roof will change direction. The edges of the roof are comprised by the verges, abutments, and eaves. There are also different types of trussed roof frame including scissor frames, room-in-attic, clerestory, and the triple howe. The scissor frames and gives a vaulted or cathedral ceiling effect. The room-in-attic offers living space in the attic. The clerestory allows for a high wall with a band of narrow windows along the top. Page 5

Laying asphalt shingles on a roof pitch - Manual January 23, filed in: To lay asphalt shingles, is just at a roof pitch cheaper and less complex than the laying of slate or Tondachschindeln. Prepare your roof with roof pitch ago Measure the roof area you want to cover with shingles. Buy corresponding insulation and roof battens enough that you can use as a construction. Insulate the roof first, if it is over the living area. If you want to only cover a garden shed or shed roof insulation is not required. You should, however, apply in any case, a water slide. Before the shingles are applied, you should definitely put on a stable substructure of battens value. When you have completed all preparations on the roof, you should first mix your roof shingles with each other, because even with the same manufacturer and the same production number color differences occur. To replace the asphalt shingles on The higher the slope of your roof, the more nails you need. In addition, it should still work here with bitumen adhesive. Now lay the first row of your shingles. To do this, start flush with the bottom edge of the roof. Cut the sheet so that you start with a full shingle. The roofing nails hitting only to the extent that they affect the shingles, but does not penetrate the material. The nails are about 2 cm above the incision taken every 2. For the second row you cut the first shingle in half so that joints do not meet with those from the first row. The second row should be the first overlap so far that the lower edge of the shingles is flush with the notches of the first row. Now you will continue to offset and overlapping the asphalt shingles on your roof pitch. At the edges and cross-wind areas you should stick to your shingles with bitumen adhesive. Depending on the manufacturer, it may be necessary that you also have to deal with a gas torch the shingles. Suggest a no more nails than is necessary. Although perhaps your first web asphalt shingles do not succeed on a roof with roof pitch right away, so you are proficient with each row. Page 6

7 Chapter 6 : blog.quintoapp.com: Customer reviews: Roof Construction Manual, English Edition New Roof Construction Manual Cedar Shake & Shingle Bureau History This manual is intended for use with Western cedar shake and shingle roofing and siding products. EHT explores some basic roof framing techniques, from layout to installation. Roof framing is one of those carpenter skills that appears quite complicated, and indeed, some roof designs are difficult. Roofs are basically five types: In many cases with purchased house plans, the details of the roof construction, including rafter design, are included. Pre-constructed trusses have also become increasingly popular. They are constructed at a factory to match your building and delivered on site. They do, however, require extra manpower and lifting equipment to install in place. You can also build your own trusses if you have the equipment, or can rent the equipment to install them. Simple roofs, such as a shed or the common gable, are fairly easy to construct, even without plans, if you understand the basics and a little geometry. Roofs are framed in five basic designs: The gable is the most common, and it can be complicated with multiple roof lines, including valleys and dormers. For a shed roof you only need to know the rise, span and line length. Span is the measurement across the building from outside supporting wall to outside supporting wall. Run is half the distance of the span. Rise is the measurement from the centerline of the span to the top of the roof line. Line length is the measurement from the outside of the supporting wall line to the centerline of the roof at the top of the rise. The framing of a basic gable roof is based on a right-angle triangle, and the various roof framing components fit the triangle. The rise, or height of the roof at its peak, is the altitude of the triangle; the run, or half the building span, is the base of the triangle; and the line length, measurement from the roof peak to the building wall, is the hypotenuse. You will also need to know the desired pitch of the roof. Pitch is the slope or angle from the wall plate to the roof ridge line. Pitch can vary a great deal, from a shallow slope up to a very steep pitch. Pitch also has its own denotation, determined by the rise in inches in 12 inches. Having the correct pitch is important. In many instances, a certain pitch may be necessary or even required by local codes. Pitch is determined by snow loads, other weather factors and the covering to be applied to the roof. For those in the northern parts of the country, an 8 in 12 pitch, or more, is commonly used to keep excessive snow loads off the roof. Those in the southern climates may utilize lower pitches. For lower pitches, a built-up or continuous roll roofing must be applied to keep the roof waterproof. Pitch is the amount of angle or slope the roof has. A framing square is traditionally used for laying out the roof and determining pitch. After you determine the rise, span, run, line length and pitch, the next step is to lay out the rafters, or mark the cuts on a pattern rafter to create the roof. We will show two methods of laying out rafters; one using a traditional framing 2-foot square, and the second using the new C. The first step is to lay the square on the end of the rafter board and locate 8 inches on the tongue the rise, and 12 inches on the blade the unit of run. Multiply this by the run of the building. A framing square is used to lay out the rafters. You should make this first pattern rafter on the straightest board you can find. If there is any curve in the board, lay out the rafter so the crown is up or facing away from you. Experience has shown that the weight of the roof will gradually flatten this crown. If the crown were to be positioned down, the roof could eventually sag. Then lay out the rafter as shown on the next page. Position the square with both the 8 inch on the outside edge of the tongue and the 12 inch on the blade on the upper edge of the board. Mark along the backside of the tongue. This is the plumb cut for the roof ridge. Also exclude the overhang at this point. Holding the square in the same position as before, mark down to the side of the tongue. Add the length of the overhang beyond this mark and mark it. Note the square is turned over. In the example shown this is 12 inches. Cut the rafter at the ridge line and at the overhang line. Cut the notch, first with a handsaw or portable circular saw, and then finish the cut with a handsaw. Continue moving down the rafter and marking plumb cuts, including any odd figures. Then lay the rafters out on a smooth, flat surface, with a 2-by between them at the ridge line. Measure to make sure the rise, run and span are correct. You may wish to test these on the building before cutting the rest of the rafters. Make sure you carefully follow the pattern rafter. A number of years ago I was constructing a two-story building. One carpenter laid out and began to cut the rafters. He became ill from the extreme heat of the day and another carpenter took over for the last third of Page 7

8 the rafters. When the roof framing was completed and decking installed, there was a built-in sag. Pivoting Square Method The new C. Hanson Pivot Square makes the chore of laying out a roof quite simple. I wish I had this tool a number of years and buildings ago. Hanson Pivot Square makes it eady to lay out rafters. The Pivot Square has three edges corresponding to the three sides of a triangle. Degrees and rise are marked on a blade attached to the pivoting arm. With the common rise figures facing you, and the raised fence on the right, the bottom represents the base of the triangle the run and the right side the altitude the rise. The long adjustable edge represents the hypotenuse of the triangle, or the line length. Simply adjust the square to the desired pitch and lock in place with the knurled knob. You can then use the square to transfer the angle for the cut to the lumber. Or you can hold the square in place and use it as a sturdy guide for running a portable circular saw. One great feature is that the pitch is also marked on the tool in degrees of angle. Determine the pitch, then you can set a miter saw or compound miter saw to make cuts in degrees that conform to the desired pitch. These figures are determined on the back side of the square. This tool takes a lot of the figuring and guessing out of creating hips and valleys. And, the tool is even more versatile and can be used for other cuts as well. A series of numbers run along the center of the graduated arc of the adjustable blade on both sides of the tool. Each of these numbers represents the complement of the corresponding angle along the edge. The sum of these two figures always equal 90 degrees. For instance, when you set the square for 20 degrees, the complementary angle of 70 is directly aligned. You can make the degree cut following the set angle, flip the tool over and make the complementary degree cut to create a perfect 90 degrees. The square also comes with three leveling vials which make it easy to measure the pitch of existing structures. To measure pitch, first position the hypotenuse of the square on the roof, running straight up the pitch. You may use a 4-foot level to set it on for more accurate measurements. The outer end, or number 9 on the hypotenuse or adjustable blade, should be at the top or upper side of the pitch. Loosen the lock and adjust the square until the level vial on the base reads level, then lock the setting. To lay out a rafter with thepivot Square, first determine the pitch and set the square to the correct pitch on the Deg. Position the square with the base or raised edge on top of the rafter board. Mark the plumb line for the ridge line cut near the end of the rafter board. Determine the rafter overhang, move the square to that position and make another plumb cut mark. Then use the square to draw a short plumb line parallel to the others, down from this mark to the bottom edge of the board. Make a second plumb cut at the line length measurement on the rafter. To begin layout with the ridge board plumb cut, set the adjustable angle-blade to the desired pitch. Position the square in place and mark for the cut. You can also hold the squre in place and use it as a portable circular saw guide. This requires laying out a level line on the tail of the rafter. To do this, do not make the tail cut until this has been established. Draw the sub fascia and finish fascia board on the end of the rafter and against the plumb tail cut. Use the bottom edges of these boards to mark the level line cut. In some instances the bottom edge of the rafters are also cut with a level line.
