Most homeowners don’t even know what roof underlayment is — never mind giving it much of a thought.
Yet contractors understand this layer of protection between a roof deck and roof covering may serve as the last line of defense when wind, water and other worries make their way below the primary surface.
While the basics of roof installation have not changed dramatically over the years, professionals now have more product choices than ever. Felt roofing underlayment has been the go-to product for decades — yep, the kind your Pop used. While still widely available, felt underlayment now shares shelf space with more premium alternatives, such as Atlas Roofing’s Gorilla Guard® line of engineered underlayment.
Engineered underlayment is the high-performance answer to those seemingly sudden complaints about traditional felt. The “old” felt has now fallen out of favor with some contractors who say it wrinkles, tears and splits too easily and tracks asphalt when warmed by the sun.
The shift in attitude has come about as the prevalence of lighter-weight shingles has made it harder to hide irregularities below. Some manufacturers of traditional felt have undertaken cost-saving measures that have brought about low quality in some contractors’ eyes.
Capitalizing on industry expertise and innovative product knowledge, Atlas has created a product with a proprietary blend of powerful substrates. A material that is stronger in performance yet simple to use. This high-performance solution is tougher to tear and lighter than traditional felt. Additionally, it is easier to lay flat.
Consider this about Atlas engineered underlayment: Third-party, independent testing has shown EVERFELT™ Spec 30 is 40 percent lighter than traditional specification felt, 207 percent higher in tear strength, and 280 percent stronger in peel resistance strength.
So it’s no surprise that some contractors now use engineered underlayment as a standard rather than an upgrade for many applications these days. It is easy to install too, when roof decks are properly prepared by being made smooth and clean. Simply said, engineered roof underlayment has used innovation to create new life for an old product.
Good contractors know it is important to choose wisely when choosing a roof underlayment type. Roof underlayment provides a host of benefits, after all. According to the National Roofing Contractors Association (NRCA), underlayment helps to: -Weatherize a building until the shingles or other primary covering is put into place -Conserve energy inside a home by reducing airflow -Smooth out any unevenness along roof deck for better application of roof covering -Enhance fire resistance
Using the right product the first time can save a bundle in time and labor costs.
