Screws vs Glue Which One Is Better
For homes with low-slope roofs, EPDM membranes are the go-to roofing material. Due to their lack of elevation, flat roofs are more exposed to UV rays and tend to have trouble with ponding water. But thanks to their water-and-UV-resistant composition, EPDM membranes are well-equipped to handle these challenges.
For homeowners with low-sloped houses, the more relevant question here is not the type of material; rather it’s how the membrane should be attached. Should the membrane be mechanically attached or fully adhered to the insulation layers underneath? John Peters Roofing, a top roofing repair contractor in the state, lists the benefits of each option below.
Screws vs Glue Which Is Stronger?
Mechanically Attached Roofs
About 80% of homeowners choose mechanically attached EPDM roofs, making this the more popular choice of the two. To mechanically attach a roof, screws are driven into the underlying insulation layer and metal deck underneath. The membrane’s outer edges are then sealed using a hot air gun.
This method of attaching your roof is popular because it’s faster and more cost-effective. Your local roof contractor is also likely to favor this type of method because it’s easier to inspect, a quality that will be advantageous when manufacturers inspect your roof for warranty purposes. And in most cases, homeowners don’t encounter any significant problems with this type of roof. If, however, you live near the coast, you may want to consider installing a fully adhered EPDM roof.
Fully Adhered Roofs
When strong winds pass through mechanically attached roofs, the difference in wind pressure causes fluttering in membranes. And these may have implications on your heating costs. A fully adhered roof, which is glued to the insulation layer, is unlikely to experience this kind of problem.
If, however, you’re still not sure about which type to choose, it would be a good idea to consult a certified contractor.
