As any roofing contractor knows, there are lots of factors to consider when choosing an underlayment. Some underlayment works better for one type of roofing over another, while other underlayment products are better designed to withstand moisture, UV rays and other environmental concerns. If you’re wondering which Epilay product to choose for your roofing products, here’s an overview to show you which products will work best in a variety of situations.

Choosing Based on Roofing Material

In general, heavier roofing materials should be backed by a heavier-duty underlayment. This not only prevents damage to the underlayment itself, but also the roof deck. Read on for a list of common roofing materials and the Epilay products that work best with them.

  • Asphalt Shingles: Asphalt shingles are a lightweight roofing option, which means that any Epilay underlayment will work as a barrier between the roof deck and the shingles. Contractors looking to save money can use Protectite Superior, which is a lightweight 7 MIL underlayment. Choose one of the heavier Protectite underlayment or Plystik Plus for greater protection to the roof’s deck.
  • Residential Metal Roofing: This is another lightweight roofing material that works well with Protectite Superior. As with asphalt roofing, homeowners may desire a thicker underlayment or a product with a longer warranty, so you may also choose to use a heavier underlayment beneath metal.
  • Slate Roofing: Since slate is heavier than many other types of roofing, it is recommended that you use a heavier underlayment beneath it. Choose Protectite Ultra, Platinum or Plystik Plus.
  • Concrete and Clay Tiles: For these roofs, we recommend either Protectite Platinum or Plystik Plus. For these heavier roofing materials, a heavy duty underlayment is a necessity.

Environmental concerns are another reason to choose one underlayment over another. For instance, in windier areas, choose heavier underlayment options such as Protectite Platinum or Plystik Plus. This way, if the primary roofing material becomes wind damaged, the underlayment will serve as extra protection for the roof deck until the homeowner is able to schedule repairs.

Choosing Based on Other Concerns

What about cold weather installations or installations in which there may be a delay between the installation of the underlayment and the roofing itself? For installations in the colder months, any of Epilay’s underlayment choices will work. Both Protectite and Plystik Plus do not get stiff or start to crack as the temperatures drop, unlike traditional underlayment, which becomes difficult to roll in cold weather.

If you anticipate labor shortages or time spent between installation of the underlayment and the primary roofing material, go with one of the Protectite options since all three are warrantied against UV exposure for 12 months. All Epilay options are designed to stand up to wind and rain, so weather-related delays won’t be a concern no matter which option you choose.

The underlayment options provided by Epilay are designed to perform well under a variety of conditions and best of all, each underlayment is versatile enough to work with several different kinds of roofing material. Use this guide to choose based on roofing material and to narrow down your selection based on anticipated weather concerns or labor delays.
