Get matched with top roofers in Nephi, UT

There should be small gaps between your roof and the walls of your home, and other buildings. These small gaps let building materials shift, expand, and contract with weather and other outside forces, and they prevent moisture from wicking down walls from roofing and gutter systems. Without these strategic gaps, your home’s exterior and its finishes can sustain water damage, decay, peel, delaminate, and crack. However, there is a fine line between a smart gap and a problematic gap—all  gaps should be small, intentional, and covered or filled in with foam insulation to prevent pests from using them as access points.

Roofing felt is the most common type of roof underlayment, likely because it has been around the longest. It’s called roofing felt because it is often made of felt soaked in asphalt. Depending on the type of roofing a home has, roofing felt comes in different thicknesses. 

If properly installed and maintained, roofing felt should last between 10 and 25 years. 

Verify that your roof is licensed and insured by visiting your state's contractor's licensing association. Most states have a database to double-check your contractor's name and address against the information provided. The contractor should also display both their license and insurance on their website with links to the related agencies.

Single-ply roofing lasts for between 15 and 30 years, depending on the type you install and the climate in your area. TPO roofing has the shortest lifespan of 15 to 30 years, followed by PVC, which lasts for 20 to 30 years. EPDM roofing is the longest-lasting single-ply roofing option, with a lifespan of 30 to 40 years. Keep in mind that hail, strong winds, blown debris, and foot traffic can all reduce how long your flat roof lasts.
