Built-up roofing, also called BUR, is the most common and cost effective low slope roofing material. It can be installed with a single layer or double for better insulation.

With alternating layers of fabric and asphalt, it's finished off with an aggregate top coat to protect against weather conditions such as extreme heat from scorching suns or heavy snowdrifts in wintertime that will cause cracks if not treated properly before installation begins.

BUR is the best option for low-slope or flat roofs because it provides a continuous sealed surface that can handle water. However, roof shingles do not provide this type of protection and need to be on steeper slopes in order to work effectively with rainwater runoff.

Polyvinyl Chloride roofing is a long-lasting, waterproof and lightweight material. The piping you'd see in the building industry has been transformed into an easily folded flat sheet that can be applied to roofs with minimal labor or fuss.

Polyvinyl chloride roofing (PVC) is one of the longest lasting materials for covering your home's rooftop - it can lasts up to 50 years! It's also considered leak proof when properly installed; something homeowners are looking for these days.

PVC flat roofing is more reliable than roofs with taped seams because it's heat-welded at the seams. This means that you'll rarely have any leaks coming from your seam or flashing, and if there are some problems down the line they're easier to fix since a simple patch will do just fine!
