Membrane roofing can include different materials, including thermoplastic, thermoset, asphalt and modified bitumen. These roofing options all require proper installation by experienced roofers. How well your contractor installs your roof can affect its efficiency, appearance and lifespan.
One result of poor workmanship is seam failure. Keep reading to learn more about this roofing issue.
Why Issues Tend to Occur at the Seams
Seams are naturally prone to damage, no matter the roofing material. They require proper sealing to stay intact. Thermoplastics are heated with hot air until the material melts and combines to the following section or flashing. Roofers seal the seams of modified bitumen and built-up systems by mopping hot asphalt or using a cold adhesive.
Issues happen when both faces of the seams are not sealed simultaneously. This happens regardless of whether your contractor uses glue, asphalt, tape or a heat welder. Problems will occur in parts of the seams that the roofer didn’t seal correctly. Whether you have a commercial or residential roofing system, hiring experienced professionals will save you from costly repairs.
Other Causes of Membrane Failure
Over time, the sun’s harmful ultraviolet (UV) rays can deteriorate your roof. It’s the same for other outdoor elements, such as high winds and hail. As your roof ages, it can start shrinking and become brittle. Eventually, it would be necessary to replace it.
Another common cause of membrane failure is poor insulation installation. If the insulation isn’t secured to the roof, it will warp and form bumps on the membrane. When this happens, the seams will be strained, resulting in tears in several areas.
