I described the distinctions between synthetic and felt roofing underlays in my previous article since I encountered many homeowners who were perplexed about the possibilities for roofing underlayment for their homes. My advice to clients is to select the best synthetic roof underlayment for their roof after working with various materials in the roofing industry.

My roof has that type of construction, and I decided to utilize a synthetic underlayment since it offers superior waterproofing protection and better all-around performance. The top synthetic roofing underlayment choices and goods that Archer Roofing contractors install for homeowners are listed below:

CertainTeed’s Diamond Deck

This is a scrim-reinforced, water-resistant, lightweight synthetic underlayment used with slate, metal, shingle, or shake roofing. Compared to standard felt roofing underlayment, it is significantly more stable and tear-resistant, and its unique top surface offers excellent slide resistance even when wet. DiamonDeck is Archer Roofing’s chosen roofing underlayment because it offers best-in-class performance regarding weather protection and contractor safety.

CertainTeed’s WinterGuard

An “ice and water shield specialty underlayment” is what WinterGuard is. It is a pricier waterproof shingle underlayment that guards against ice dams and leaks caused by wind-driven rain in sensitive places. A composite substance of asphalt polymers rolled into a sheet makes up WinterGuard. The asphalt provides waterproofing.

The asphalt’s ability to stretch and cling is ensured by the polymers’ ability to make it elastic and sticky. This means that WinterGuard seals around any nails driven through it and does not rip under pressure. It won’t dry out while under warranty and adheres to a roof deck like glue. The result is a watertight barrier that protects your shingle system from driving rain and accumulated water. To safeguard our clients’ roofs, Archer Roofing installs CertainTeed’s WinterGuard on low-slope roofs, in valleys, at eaves, and around flashings.

InterWrap’s RhinoRoof

This synthetic underlayment for roofing is inexpensive since it is priced similarly to 15-lb conventional felt substitutes. RhinoRoof may be utilized in freezing temperatures without stiffening and becoming challenging to unfurl.

Additionally, unlike felt, it does not dry out, break, or leak oils in the heat. RhinoRoof won’t either: it lays flat and remains completely mold-resistant. Another factor to consider is the walking surface’s fiber grip, which is safe for roofing contractors and easy to use.

GAF Deck Armor

This breathable synthetic roofing underlayment is a fantastic choice for more recent, airtight homes since it protects your house while decreasing retained moisture. Deck Armor’s cutting-edge technology reduces stored moisture in your attic, enabling it to escape while preventing water from penetrating underneath your shingles and harming the structure of your roof.

One drawback is that it is less water-resistant and cannot be exposed for as long as specific synthetic alternatives. Whatever your underlayment choice, please double-check that your roofing company is putting it!
