Built Up Roofs, Modified Bitumen and Granular Cap Sheet roofing layer materials(going forward called BMG) are the premier type of roof to employ Silicone Restoration Membrane for roof restoration or roof replacement. The normal lifespan of most BMG roofs is 1 1/2 to 2 decades. BMG roofs can be replaced with a variety of roofing materials including tear-off and replacement, overlay and coating.
A roofing industry common practice is to use low cost acrylic elastomeric coatings to restore BMG roofing layers. However it is also a fact that roofers, in most instances, do not share the fact with homeowners that despite its low cost, organic acrylic elastomeric coatings are not the foremost product to use because they do not have a long product lifespan. Silicone roof coating lasts far longer than acrylic roof coating. When a roofer applies acrylic roof coatings they know going in after the job is completed that the product will not last over the long haul and eventually the homeowner will make a call when the roof starts to fail again, which means the substandard product created more work for the roofer down the road. Factoring in costs going up for a new roof down the road will be cost way more than the last one
Roofing system types that are available to overlay a BMG roof include sprayed polyurethane foam, single ply overlays, granular cap sheet overlay and thermoplastic polyolefin. Roofing overlays are quite often seen as a second roofing system. Depending on how the new roof is classified it may not qualify for any tax deductions created from energy saving tax programs.
Tear Off and Replacement
This entails taking off the entire roof except for the original roof decking. The materials removed from the tear off are thrown away into the local landfill. The replacement is then installed to replace the original roof. The major issue with this method is that it is very costly. The old roofing materials take up tons of space in local landfills. This method is bad all they way round because it costs a ton, it’s bad for the earth and it is completely ineffectual.

Silicone Restoration Membrane is one of the the smartest picks when it comes to roofing materials. The material is amazing, featuring some of the premier product statistics in the industry, installation is fast, and labor costs are low.
