Most people have heard of flat roofs. They are commonly used for commercial business all over town. But, most people aren’t familiar with torch roofing or how it is installed and maintained.
Torch roofing uses a material called Bitumen (or asphalt). This material is good for waterproofing a roof. However, torch applied roofing need s an additive to stabilize the inability of asphalt to expand and contract. In the past, asbestos was added to the asphalt. Now, roofing contractors use a modified Bitumen using other additives.
This modified Bitumen Is applied two ways. One is called SBS Self-Adhered or mop applied and the other is APP (atactic polypropylene) torch applied. The torch applied (APP) type of the modified Bitumen is sometimes marketed as a rubber-like membrane, which is misleading. The additives used to make the modified bitumen don’t actually contain rubber at all; APP uses plastic-type modifiers, not rubber.
APP Modified Bitumen requires a torch and propane tank to apply to a roof. The roofing material creates an impermeable roof with an average life of between 15 and 20 years. It is ideal for flat roofs because it offers protection from rainwater, which collects on the roof surface. The cost is only slightly more than the traditional tar and gravel roofing material that is frequently used. APP torch roofing provides better results than tar and gravel. Most building owners think that the additional cost is well worth it.
Another benefit of APP roofing over tar and gravel roofing is the smell. The tar can leave behind noxious fumes, which sometimes drives homeowners to temporarily move out to avoid the smell. Since, torch roofing does not contain tar, it does not have bothersome fumes associated with its installation.
APP roofs are also fire resistant and heat resistant. With additional coatings, torch roofing gains in fire resistance. APP torch roofing also deflects harmful UV rays that can deteriorate other roofing materials. It also won’t melt in the sun or become brittle over time, like tar and gravels roofs.
If installed properly, torch down roofs are low maintenance and tear and puncture resistant. This means you save some money on roof repairs. When it is time to repair or replace the roof, a new roof layer can be added easily. This also saves the cost of labor from tearing off an old roof.
Since APP roofing is applied using a torch on top of the building, only experienced professional roofing contractors should install this type of roofing. The dangers of working with an open flame on a building or residence should be taken very seriously. And Guardian Roofing is the expert contractor to call for your roofing needs.
