The Three Main Types of Flat Roofing
Many houses and commercial buildings in Denver feature flat roofing, instead of sloped roofs. Flat roofing has been in use for millennia, especially in arid regions where heavy rainfall isn’t a major threat. Denver’s climate is classified as “semi-arid,” and we receive fairly modest precipitation. Because of the local climate, flat roofing is fairly common. There are three main varieties of flat roofing that can be installed on a structure: built-up roofs, modified bitumen roofs, and rubber membrane roofs.
- Built-up roofs is the most common type of flat roofing found on Denver homes and businesses. It’s constructed from several layers of bitumen (i.e., asphalt), covered by a coating of a different material. The layers are called “ply sheets,” and are often reinforced with fiberglass mats. Built-up roofing provides excellent waterproofing and ultraviolet protection, as well as being relatively low-maintenance. With Denver Roofing types, Built-up is commonly used on residential structures, although for commercial buildings, other types of flat roofing are more likely to be used.
- Modified bitumen roofing is manufactured from a combination of asphalt with various modifiers and solvents. Many people consider modified bitumen roofing to be superior to other forms of flat roofing because, when installed correctly, it creates a perfect, impermeable seal, and it’s less likely to develop leaks over time. It’s also faster and easier to install than built-up roofing, as well as often involving a lower installation cost.
- Rubber membrane roofing is constructed from ethylene propylene diene monomer (EPDM), a type of rubber material similar in consistency to an inner tube. This lightweight but highly durable material is specially engineered to resist damage from UV sunlight.
The Benefits of Flat Roofing
Whatever type of flat roofing you have on your home, a flat roof has a number of benefits when compared to sloped roofs. Some of the advantages of flat roofing for Denver homes and commercial structures include:
- Flat roofs are easier to climb onto and inspect than roofs with a significant pitch, due to their stable horizontal surface.
- A flat roof is easier to clean than a sloped roof.
- Flat roofs cost less to install than sloped roofs, although they do need to be re-coated and re-sealed every few years to prevent leaks.
- Heating and cooling units can be installed on top of a flat roof.
- Flat roofing can often be converted into a useable space like a deck or greenhouse.
- Flat roofing is ideal for placing solar panels, an excellent way to increase your home’s energy efficiency and reduce your carbon footprint.
- In terms of architectural design, flat roofs are quite versatile.
- Flat roofing can last for a long time, especially rubber membrane roofing, which can have a lifespan of up to 40 years.
Flat roofing is a versatile design choice, as well as an economical option, that’s well suited to homes in Denver. In our arid climate with modest levels of rainfall, drainage isn’t as much of a concern as it would be in other areas with wetter climates. A flat roof is also a great place to install solar panels for your home. All in all, the various types of flat roofing are all viable choices for houses and other buildings in the Denver area, conferring many benefits in terms of cost, maintenance, and durability.
