You’ve probably heard the term “roof underlayment” mentioned at some point. It refers to a thin waterproof material installed between the roof deck and asphalt shingles, providing an additional layer of protection against water damage and moisture infiltration. If you plan on having a new roof system installed this season, make sure it comes with a good underlayment. Here’s how you can pick the right one for your needs.
Rubberized Asphalt for Premium Watertight Performance
Roof underlayments come in different types, and if you’re looking for the top-shelf option, rubberized asphalt is definitely it. Flexible and self-sealing, this underlayment is best used in the more leak-prone areas of your roof, such as the eaves, chimneys, vent pipes, skylights and dormers. As its name implies, rubberized asphalt is primarily made of rubber polymers and asphalt, but the exact composition may vary depending on the manufacturer. The premium price of rubberized asphalt can be a turn-off, but if you’re okay with spending more, then its performance should be sufficient for your needs.
Asphalt-Saturated if You’re on a Tight Budget
Asphalt-saturated offers waterproofing performance at value price. It used to be the go-to underlayment option before newer and better alternatives, like non-bitumen synthetic and rubberized asphalt, were invented. Asphalt-saturated is cost-effective and readily available, plus its waterproofing ability is usually good enough for some homeowners. But keep in mind that it also easily breaks and doesn’t last as long as its counterparts.
Non-Bitumen Synthetic — Full Stop
Non-bitumen synthetic underlayment costs more than asphalt-saturated but is tougher and offers better resistance against moisture and tearing. Compared to rubberized asphalt, it’s also more cost-efficient. Made of woven or spun polypropylene or polyethylene, this underlayment is the ideal option for those looking for something reasonably priced without sacrificing quality and durability. Some prime examples of non-bitumen synthetic underlayment include the GAF Deck-Armor™ and Tiger Paw™ Roof Deck Protection offered by Twin Cities Siding and Roofing.
