A layered or hot built-up roof system is the main choice for those with a roof pitch at 3/12 or less. Standard shingles can allow water to blow up under them on these types of roofs. A torch down modified roof is one way to meet the building code and properly seal the roof.
While a hot roof system sounds dangerous, this method can actually be done in a completely safe way. There is zero risk of fire if this method is properly applied. Rolling the material out and applying the torch to it is both effective and safe.
To apply the torch down modified roof to your home, you need to follow three steps. Asphalt felt paper forms the base layer so it needs to be nailed down before anything else is done. Galvanized roof edging material needs to go around all of the roofing edges. The entire perimeter of the roof needs roofing mastic laid down in a 6-inch layer. Be sure to go over the metal because the tar won’t stick otherwise.
Once you follow the three steps to prep the roof, you are ready to blast it with the tar layer. You can practice first on the ground to get yourself used to the idea or simply hire a professional to install it. The entire process takes a few minutes and requires you to start blow torching the tar near the bottom. Then roll the roll with your foot as you move forward. Cut off the roll in increments of ten feet each.
Now that you know how you can apply the roof without a professional, there are a few safety items you can benefit from having. A fire extinguisher and a five-gallon bucket of water are essential just in case. Wear boots or non-nylon shoes, eye goggles, long-sleeved cotton shirt and leather gloves while doing the process.
A torch down modified roof can be done on your own. If this process still sounds daunting, contact a professional to do it for you.
