All roofs come in a variety of shapes, sizes, and types – including shingles, metal roofing, and flat roofs. Whether you are replacing a roof or building an extension to your home, you have options. Let’s hone in on flat roofs, as there are choices available depending on the structure. How do you choose the best one? Continue reading to learn more about flat roofs and what makes them worthy of your home.
What is a Flat Roof?
When you hear the term “flat roof,” you might wonder how one would ever be able to survive a downpour. That’s why in most situations, there’s actually a low slope to this roof – allowing it to drain water straight to your gutter system. They are most commonly found on porches, rear additions, and troughs.
What Materials Are Available?
Flat roofs have historically been covered with what is known as “built up”. This is layers of felt with melted asphalt mopped in between them. They work well but have some problems. The UV exposure will crack it with time and the weight of these systems can be problematic, particularly with snow and ice loads. They are also messy applications and not very environmentally friendly. Fortunately, technology has improved.
One of the more popular materials used in roofing today is modified bitumen. This product is probably best visualized as a one-piece, rolled asphalt shingle. As it is rolled onto the roof, it allows for fewer seams and offers a surface that is better able to handle slow water shedding – water that takes longer to drain. It even comes in multiple colors to complement asphalt roof singles.
TPO (Thermoplastic Polyolefin)
A combination of polyolefin, glass, and rubber, TPO is a single-ply roofing system. It can be as wide or thick as needed, minimizing seams and increasing resistance to puncture. TPO’s seams are heat welded to ensure their strength and endurance. Have an existing roof that’s just barely holding up? This material is an economic alternative because of its ability to be installed over that old structure. Overall with TPO, your roof will have a longer lifespan, require less maintenance, reduce heat transfer with its high reflectivity, and you could have a longer service warranty.
