You already know that shingles are the outermost layer of your roof, but did you know the layer between the shingles and your wood roof decking is just as important? In days gone by, the use of an asphalt paper-based product generally referred to as “felt paper” under roof shingles was a very common practice. Not only because it worked as a protective layer between shingles and the wood roof deck, but because it was basically the only material a builder could use. Today, felt is still the base level of protection allowed by most residential building codes.

This layer of protection between the shingles and the roof deck is essential to ensure that any water that does get past the shingles won’t be allowed to come in contact with the wood roof decking. While felt paper may still be allowed per residential building code, it is more apt to rip under certain wind conditions and should be covered with shingles as soon as possible after being installed. In the 21^st century, other products have been developed that go above and beyond the use of felt paper.

This is why Tilson chooses to use a product called RhinoRoof. RhinoRoof is a product manufactured by a subsidiary of Owens-Corning and is 12x stronger than traditional 30-pound (#30) felt. It’s a synthetic roof underlayment that is almost impossible to tear by human hands. Another benefit of using RhinoRoof is that it lays flat, will not wrinkle and won’t absorb water.

RhinoRoof’s durability is top-notch and can be exposed to wind or sunshine for weeks without sustaining damage. The quoted level of coverage provides roof deck protection from UV exposure for up to 60 days. Not only is RhinoRoof better at protecting against the elements, but it is also better for installers. The fiber-grip slip-resistant walking surface ensures that installers remain safe while your roof remains undamaged by the weight of the workers.

Tilson also likes using RhinoRoof because it’s a more sustainable option than felt. #30 felt is made from asphalt and can leach oil. With RhinoRoof’s more sustainable nature, it’s a mystery why more builders don’t choose to use it.
