Flat Roofing Options

Flat roofs are the cool kids in school – minimal slope, durable and a great choice for commercial buildings and some residential homes. They are not without their challenges though and proper maintenance and care is required to ensure long-term performance and longevity. A wide variety of flat roof sheeting options exist, so selecting the right one for your building will depend on a number of factors such as climate and budget. Consult with a roofing professional to evaluate your needs and recommend the best choice.

EPDM (Ethylene Propylene Diene Monomer) is a popular and affordable option. It offers resistance to weather and chemicals, as well as flexibility. This material is commonly used in industrial and commercial applications.

TPO (Thermoplastic Polyolefin) is a single-ply membrane that’s becoming increasingly popular for its energy efficiency. This material is reflective and can reduce the amount of heat absorbed by the roof, reducing cooling costs. It also has great durability and comes in a variety of colors, offering a wide range of aesthetics.

PVC (polyvinyl chloride) is another single-ply option. It’s also a highly durable and resistant material to UV radiation, chemicals and extreme temperatures. Its fast curing time and high tensile strength makes this material ideal for flat or low-sloped roofs.

Modified bitumen is a common roofing solution. It is a combination of asphalt with additional polymers and can be either self-adhesive or hot-applied. This material has a granulated surface and can be produced in either a smooth or textured finish. It’s also available in a variety of layer permutations that can boost its overall performance.

The type of insulation used on a flat roof will affect its lifespan and ability to prevent leaks. If the insulation is installed below the roof deck, it’s referred to as a “cold” roof and is generally discouraged in cold climates. In this type of roof, condensation can promote mold and fungi growth.

Leaking is a major concern for many owners of flat roofs, and it can be especially difficult to identify the source of the problem. This is because water can travel a great distance before it is visible to the naked eye or penetrates into a building. To detect leaks, experts now use infrared imaging to read heat that is emitted by wet insulation.

Regular roof inspections and maintenance are key to maintaining a functional and safe flat roof system. If problems are identified, prompt repairs will help avoid costly and inconvenient consequences. It’s also recommended that all gutters and drains are cleaned regularly to avoid blockages. This will help prevent puddling, which can lead to damage and roof failure. It’s also important to inspect for any signs of water damage, including discoloration or stains on walls and ceilings. These issues may be a sign of serious structural damage to the roof. If you see any of these signs, contact a roofing professional right away.
