Flat roofs have greatly improved in recent years — gone are the days of limited design and potentially leaky flat roofing. New technology has enabled roofing companies in Worcester, MA to design a slight roof pitch which creates a mild slope that drains water. It is vital to know that a good flat roof is not really entirely “flat.”
Aside from the advent of new technology in sloping, there are improved materials on the market that increase a roof’s longevity and durability.
That said, homeowners can choose from the following kinds of flat roofs:
Built-up roof (BUR)
This is a tried-and-tested flat roof type built from hot tar and gravel, ballasted with river stone. This type of roof is composed of many layers, which make for great insulation and durability. However, the roof tends to be very heavy, so you need strong joists to support it.
This roof is similar to asphalt roofing, but with polymers added to the ix. The addition of such a material makes this option more durable than its traditional counterparts. Because it takes on a reflective quality, on account of the polymer, this type of flat roofing can help save on energy as heat bounces off the roof. However, in case of a fire, the material may do more to fan the flame than put it out.
More often than not, this roof is made of an ethylene propylene diene monomer (EPDM). The material looks like an inner tube, and can resist sun damage. It is typically anchored with fasteners or glued to keep it in place. The roofing material is light, yet it is tear and scuff-resistant.
If you choose to go with a flat roof for your property, be aware of the pros and cons. That way, you avoid potential problems with your roofing system, in the long run. Consult with your contractor on the best material for you.
