When installed properly, a membrane roof protects your home from the elements, provides insulation and prevents water from finding its way indoors. Unfortunately, a membrane roof can sometimes disintegrate at the seams. Barnett Roofing explains the reasons why this happens.
1. Weathering
Long-term exposure to the elements can eat away at your membrane roofing system. A variety of elements, from rain and snow to wind and heat, can cause the material to shrink and become brittle. While this is normal and expected, you can head off potential seam failure by making sure the entire system is inspected regularly by a reputable roofing contractor.
2. Inadequate Insulation
Insulation must be fastened securely to your membrane roofing system. Otherwise, the membrane roof will warp and cause tiny bumps beneath the material. If not addressed promptly, the material will start to rise, pulling the membrane material further until tears form in various places, including at the seams. This exposes the roof to further damage caused by the elements.
3. Poor Installation
Another common reason for seam failure is improper installation. Keep in mind that overlapping seams don’t necessarily mean they’re fully sealed. This is one detail that inexperienced contractors frequently overlook. Other common mistakes include not applying enough weight with a roller and not letting the melted membrane reach the proper temperature during installation.
Seam failure can be avoided through proper installation. To ensure you get the most out of your investment, you must work with reputable contractors that take the necessary precautions and perform the installation procedures according to manufacturer standards.
