Types of Flat Roofing Systems

Flat roofs are continuously gaining popularity in today’s architecture due to the fact of their ability to involve the long, flat lines of the natural landscape. A flat roofing system is not, in fact, flat, as it contains a slope of around 1/8 inch to help in the drainage of rain and snow. More budget friendly to install than a pitched roof, a flat roof is also safer and more comfortable to access and can be used as a place to sit.

At the center of any flat roof, installation is choosing on the type of roof that best fits your style of home, its intended use, climate, and your budget. The three main types of materials and techniques used in installing flat roofs provide homeowners various benefits and disadvantages.

Asphalt Roll

As one of the oldest flat roofing type and one of the most affordable, asphalt roll roofing is basically a flat layer of asphalt shingles. Compiled from layers of asphalt or fiberglass felts, it commonly has a lifespan of around 10 years.

Built Up Roof

A built-up roof (BUR) is a layered roofing system that interchanges plies of roofing felt, waterproof material (typically made of fiberglass), and hot tar (bitumen). Although fire resistant and affordable, the installation of the roofing is smelly and messy. It can last up to around 30 years.

Single Ply Roof

Single-ply roofing systems use a single layer of material. Lasting up to 30 years, single-ply roofs can be manufactured from various materials. Some of the most common are EPDM (ethylene propylene diene monomer, a type of rubber), PVC (polyvinyl chloride, a kind of plastic), and thermoplastic polyolefin (TPO, rubber reinforced for protection from the elements). Specialized bitumen is often used as a wear surface in a single ply flat roof system.

Sprayed Polyurethane Foam

Sprayed polyurethane foam (SPF) roofing is sprayed on as a liquid on top of an existing roof, with no need to remove the old roof. When the foam dries, it is treated with a protective coat for added safety. SPF roofing is lightweight, flexible, and a magnificent insulator. It can last 30 years or more, even though the protective coating may need to be reapplied every 10-15 years.

Flat Metal

Typically made from interlocking panels of steel, aluminum, copper, iron, or other types of metals, flat metal roofing, commonly known as standing seam roofing, is very lightweight but very durable, usually lasting up to 50 years or longer.
