Steps to Install torch down roofing
Torch down roofing is composed of altered bitumen sticking to fiberglass layers. Torch down roofing helps in preventing moisture buildup and doesn’t need much of maintenance as well. The installation process is relatively straightforward, and all you have to do is follow the steps mentioned below:
- Step 1: To install the new roof, first, you have to remove the old roofing and debris to make for a clean site. Many times, torch down roofing can be placed on top of old roofing; be sure you know what you’re getting into.
- Step 2: Take the metal flashing and secure it to the roof area edges to hold things in place.
- Step 3: Apply some primer to the metal flashing as it would allow your torch down roofing to stick even better.
- Step 4: Take your fiberglass sheet and lay it on the old roofing area’s topside, making doubly sure that it is completely even and flat.
- Step 5: Using a nail gun, adequately nail the fiberglass to the surface of the roof. The ideal way to do this would be to leave a spacing of 5 inches between every nail.
- Step 6: Properly roll a layer of altered bitumen over the sheet of fiberglass.
- Step 7: Using a knife, slice the modified layer of bitumen to an appropriate size. Then extend and stretch the modified bitumen to cover even the odd angles or far-reaching corners.
- Step 8: Expose half of the fiberglass sheet underneath by rolling up half of the modified bitumen and then fire on its underside using a flame torch, in a slow, steady motion for even heating.
- Step 9: Now that the bottom of the bitumen is molten, roll it back on top of the fiberglass sheet while it keeps continuing to liquefy. Use a sturdy pair of boots to press down the bitumen so that it sticks nicely.
- Step 10: Now to the same thing you did in step eight, but with the other half of the fiberglass sheet and the bitumen.
- Step 11: Repeat all the steps from 4 to 10 twice to make 3 layers of fiberglass and bitumen lying on top of each other, while an additional layer of bitumen lies on top.
And that’s it! These are all the steps you need to follow to make sure your torch down roofing is installed the way it should.
