The Best Types of Flat Roofing Materials in 2023

Your building’s flat roof has seen better days.

It leaks when it rains. It needs to be replaced soon — and you need to find the best flat roofing materials to fix it.

But there are so many out there. How do you know which one is right for you? Choosing takes a lot of work, especially as you have to make a significant investment.

We make it easy. Here’s our in-depth guide to all the ranges you can find on the market.

Built-Up Roofing (BUR)

Built-up Roofing is a classic flat roof system made of many layers of bitumen (asphalt or coal tar) and fabrics, usually fiberglass, that hold the layers together. These layers make a strong barrier that can stand up to the weather.

By changing the number of layers, BUR systems can work differently and last for a long time. Gravel or mineral pebbles are often mixed into the top layer to protect against UV light and make the roof less likely to catch fire.

Modified Bitumen Roofing

Modified bitumen roofing is an evolution of traditional BUR systems. It incorporates modifiers such as plastic or rubber to enhance the material’s elasticity, durability, and resistance to extreme temperatures. Modified bitumen comes in rolls and can be applied using a torch-down method (heat-welding the material) or cold adhesive.

EPDM Roofing

EPDM is a synthetic rubber roofing material made from ethylene, propylene, and a diene monomer. It’s available in large sheets mechanically fastened or fully adhered to the roof substrate. EPDM roofs are known for their exceptional durability, flexibility, and resistance to weathering, UV rays, and thermal shock.

Thermoplastic Polyolefin (TPO)

TPO is a single-ply roofing membrane known for its energy efficiency and white reflective surface. It’s heat-welded at the seams, forming a continuous and watertight seal. TPO is resistant to UV radiation and chemicals, making it a popular choice for commercial roofs. For a reliable TPO installation, contact Rock House Roofing for your commercial roofing needs. 

Spray Polyurethane Foam (SPF)

SPF roofing involves spraying a liquid mixture of polyurethane foam onto the roof, where it expands and cures to form a seamless, highly insulating, and water-resistant layer. SPF conforms to the roof’s shape, making it suitable for complex structures and irregular surfaces.

Metal Roofing

While often used on sloped roofs, metal roofing materials can also be adapted for flat roofs. Options include standing seam panels and metal shingles from steel, aluminum, or copper. Metal roofing offers durability, energy efficiency, and many design possibilities.

PVC Fleece-Backed Membranes

These roofing membranes consist of PVC with a fleece backing, providing additional puncture resistance and protection against substrate irregularities. The fleece directly applies to various substrates without extra insulation, including concrete and metal.

Silicone Roof Coatings

Silicone coatings are liquid-applied roof materials that form a seamless, waterproof, and reflective layer over an existing roofing system. They are often used for roof restoration projects, extending the life of aging roofs while providing energy-saving benefits and weather resistance.
