6 SCG Concrete Roof System 1.Ridge Installed in line of roof ridge. (3.3 tiles/m) 5.Hip End Ridge Installed at end of Hip ridge. 2.End Ridge Installed at both ends of roof ridge. 3.Verge Installed as gable end of gable form roof. (3 tiles/m) 4.Verge End Installed at the lowest end of gable end. 6. Two ways Ridge Installed in roof ridge line for reversal ofridge cover direction 7. Three ways Apex Installed as closure at connecting point of 2 hip ridge lines jointing with a roof ridge line in Y shape of Hip from roof. 8.Four ways Apex Installed as closure at connecting point of 4 hip ridge lines jointing together of Hip form roof.

8 7 Things you should Check before Roofing 1. Checking Pitched roof 2. Checking the Squareness 3. Checking Rafter level 4. Checking Strength of roof structure 5. Checking Fascia level 6. Checking 3 points of Batten Space 7. Checking reinforced concrete wing

9 1. Checking Pitched roof θ 17 Minimum 31 cm. 60 cm. Significant 70 cm. 100 cm. Note : In case of pitched roof less than 22 o, should checking maximum length of Rafter. (For decrease leaked area)

10 1. Checking Pitched roof Criteria for Maximum length of Rafter Degree Length of Rafter (m.) Example

11 Maximum length of Rafter Pitched Roof 18 O, Length of Rafter15 m. 10 m. 6 m. 9 m. Leaked * For the example, should install Roof Sarking along the leaked section, Install should overlap leaked section around 1 m.( total length is 10 m.)

12 2. Checking the Squareness

13 3. Checking Rafter level Stretch string above the roof 1-3 cm. Tolerance of Rafter Level ± 1.5 mm.

14 3. Checking Rafter level In case of Rafter have a support (purlin) that string stretched at - The edge of rafter (away from beam m - Middle point between beam and rafter support (Purlin) - Between rafter support (Purlin) and ridge board - Diagonal 6. In case of Rafter have no support (purlin) that string stretched at - The edge of rafter (away from beam m.) - Middle point between beam and ridge board - Diagonal Each subtopic, the length of string should be equal

15 4. Checking Strength of Roof Structure X X

16 5. Checking Eaves liner and Fascia Batten Top of Fascia and Top of Batten should be installed at same level. Batten SCG Fascia 6 inches Rafter Fascia Rafter SCG Fascia 8 inches Fascia

17 6. ตรวจสอบระยะแป 3 จ ด cm. 2 1 Rafter Ridge board Batten Eaves Filler Fascia * Note : Batten Space about 4-6 cm. for wet Tech Batten Space about 8 cm. for dry Tech

22 Batten Space on Several section of Rafter

23 Connecting Rafter 5 cm. 20 cm. Connecting on rafter line Connecting between rafter line * Note : Should not connect batten on the same line.

24 7. Checking reinforced concrete Abutment The reinforced concrete should cover roof tiles at least 20 cm. 20 cm. 20 cm.

31 Installation of SCG Valley Trough 2.5 cm. In case of one way Valley. Fold the Valley trough head up to the height of 2.5 cm. for make a water barrier. Fix both sides of trough flanges to upper pair of batten by 32 mm. self drilling screw. In case of 2-ways Valley. Joining both sides of valley must be connected completely then fix by screw after that paste SCG Flashing on the joint and fold the edge of SCG Flashing for make a water barrier.

37 Installation SCG Concrete Roof At the end of the trough at the eave, cut the eave cornice board to match the size of the trough groove and make both wings of the trough line up with the edge of the eave board to be certain it does not protrude too far from the eaves. In cases where the trough ends on the roof, allow the end of the trough to cover approximately half of the tile below or no less than 15cm. Flatten the end of the trough on the supporting tile to prevent the tile from buckling up. Be careful not to crack the tiles while flattening the end of the trough.
