AdvantagesModified Bitumen roofs are single ply systems that are most often roll-applied to the roof surface. They are similar to asphalt roofs but they have additional polymers in their materials that provide added protection from the elements and help in increase the lifespan of the product.
What type of roof is modified bitumen?
Modified Bitumen (MB) roofing is an asphalt-based, close cousin of the Built-up-Roof (BUR) designed for buildings with low-slope or “flat” roof structures.
What is a single ply roofing?
Single-ply is wide width sheeting meant for low slope roofs. Single-ply roofs have far fewer seams than asphaltic rolled roof systems and don’t require dangerous torches or hot asphalt for installation. They also come with prefabricated detailing accessories that make installation easy.
Which roof type would a single ply roof membrane be installed on?
Single Ply Roofing Installation Methods
A steel or wood roof might be ideal for mechanically fastened single-ply membrane roofing. Mechanically fastened single-ply roofing might be used on all types of slopes without limitations, and they are one the preferred option in hurricane-prone areas.
What is a single ply membrane flat roof?
What is Single Ply Roofing Membrane? Single ply is a flat, synthetic polymer based roofing material that, as the name suggests, provides a waterproofing layer in a single sheet. Usually supplied in rolls, the material is either entirely homogeneous or contains a reinforcement layer.
What is the life expectancy of a modified bitumen roof?
It is important to notes that modified bitumen roofs have a solid roof lifetime of approximately twenty years. This is an estimate that does not include good roofing maintenance.
Is TPO better than modified bitumen?
In general, a TPO roof is an excellent investment, considering the numerous advantages over a modified bitumen roof. The tough, tear-resistant single-ply membrane resists chemical spills, oil and grease. TPO roof systems are also UV-resistant to resist cracking and other sun damage, and fully recyclable.
How long does single ply roofing last?
