If you are searching for “residential flat roof materials“, our guide will help!
There are four main types of flat roofing materials, including:
1. Rubber Membrane
Rubber membrane roofing includes EPDM, PVC and TPO roofing systems. This type of roofing is known for its long lifespan, but there is the possibility that it can be torn by sharp objects or collisions. If tools fall or a tree limb hits the roof, there’s a chance the layer may tear or a leak is created. One advantage of EPDM roofing is the low cost of installation. However, one drawback is a lack of heat absorption, which leads to higher utility costs. More modern versions of this system come with the addition of highly reflective layers that deflect the sun’s heat away from the home.
- Average lifespan: 15-20 years.
2. Modified Bitumen
Constructed of multiple layers of roofing material, modified bitumen is more resistant to tears and leaks. When this roofing type is installed, a base layer will be attached to the roof mechanically with plates or bars. An overlap ply will then be sealed to the baser layer with a permanent adhesive. The last step is the application of granules to the roofing surface. This final coating helps keep the energy efficiency high.
- Average lifespan: 10-20 years.
3. Built-Up Roofing
Layers of gravel, bitumen or aggregate are commonly known as built-up roofing. The bitumen will be comprised of asphalt, coal tar or other types of adhesives. Built-up roofing has a long track record of being very sturdy and durable.
- Average lifespan: 15-20 years.
4. Spray-On Roofing
Sprays are made of silicone and polyurethane. This roofing continues to grow in popularity as it offers a completely seamless roofing option with the potential of utility costs savings. When installed properly, spray foam roofing can efficiently reflect heat and light. While this may seem like a simple installation process, spray foam roofing needs to be installed by the professionals.
- Average lifespan: 20+ years.
Tips To Make Flat Roofing Last
It is the responsibility of the property owner to maintain the roofing system. Regular maintenance/inspections by the professionals will ensure your roof is kept in the best shape possible. Typically, a flat roof should be inspected at least once a year, especially if any major storms have hit the area.
Here is a checklist of maintenance items in case you choose to do a simple roof inspection:
- Sweep the area clear of all leaves and debris.
- Check to see if water is pooling on the roof.
- Inspect the top layer of the roof. Ensure there are no bald spots and the gravel is even.
- Check for membrane problems, including punctures, holes and tears.
