If you’re thinking of installing a membrane roof, then make sure that you get professional roofing contractors to do it for you. That’s because these membrane roofs, while boasting impressive longevity, durability and being inherently low-maintenance, tend to shrink over time.
One of the biggest culprits behind this shrinkage is improper installation, which is why getting a good roofer to install your membrane roof for you is key. Mobley Brothers Roofing and Renovation shares a few things that you need to know about the shrinkage of membrane roofs.
Many a roofing company will tell you that membrane roof shrinkage is natural. These roofs will shrink over time, especially if you’re using ethylene propylene diene monomer (EPDM). However, the rate of the material’s natural shrinkage can be curbed by proper installation. And the opposite is true, which is why you need to get the roof installed by a proper roofing company. This is because the following can increase the pace of shrinkage.
Proper Application and Design
Curbing roof shrinkage starts with designing the roof with the shrinkage in mind. The end laps need to have alternating laps, since this will help the roof adjust properly when the material contracts – some sides will compensate for the contraction of the other. Upon application, the membrane needs to be allowed to rest for sometime, ideally around 45 minutes. This will allow the material to relax and adjust easily to the stress of installation.
