The seam sealing method varies depending on the type of roof system. For instance, thermoplastic membranes are sealed by exposing the membrane to heated air until it melts and combines with the next section or flashing. Ethylene propylene diene monomer rubber (EPDM) roofs are sealed with adhesives or sealant tapes while modified bitumen and conventional built-up roofs (BURs) are sealed by mopping hot asphalt or applying cold adhesive to the seam.
But did you know that the seams are typically where most roofing issues start? Here are the common causes of why roof membranes fail at the seams.
Poor Design
Keep in mind that insulation needs to be secured to the roof. Otherwise, it will warp and create a hump under the membrane. This may pull on the seams and cause tears in various places. In addition to that, insufficient slope designed into the deck or roof insulation may also lead to water flowing to drains, gutters or scuppers. If water is not deflected from your roof, it may contribute to premature failure of the roof membrane and flashings.
Improper Installation
It’s best to hire a professional roof installation services company to ensure your roof is installed properly, especially at the seams, and that you won’t experience the effects of poor workmanship, including leaks and punctures.
Extreme Weather Damage
Extreme weather conditions like rainstorms and snowfall may lead to shrinkage and brittleness on the membrane roofing systems. While storm damage is typically inevitable, you have to make sure your roofing system is well-maintained by scheduling regular roof inspections. During a roof inspection, professional roofers will be able to address any weathering and performance issues. If they find any issues, they will perform repairs to prevent further damage.
