The shingles may be the most visible part of your roof system, but they’re only the surface layer. Just underneath them are other important components working together to ensure your roof can continue delivering reliable weather performance. Under today’s spotlight is the underlayment, which directly contributes to the longevity and stability of your asphalt shingle roof system. Here’s what it does:
The underlayment is a thin waterproof material installed just between the shingles and the decking and above the ice & water shield protection. If water or moisture somehow runs past the shingles, the underlayment serves as a barrier that stops it from seeping through the roof system. It helps eliminate – or at least reduce – the potential for leaks, helping keep your home safe and dry against possible water damage. Underpayments are also breathable and tend to be lighter colors (white or light blue) so they don’t increase heat draw through the roof deck.
Water intrusion can be a huge problem in your roof system. If the decking and trusses, which make up the roof structure, are constantly exposed to water, it’s only a matter of time before mold and rot develop on them. When overlooked, mold and rot will gradually weaken the roof structure, causing the entire system to sag. But this won’t be an issue if the roof has an underlayment in place. It stops mold and rot from growing on the roof structure by preventing water intrusion from occurring in the first place.
The underlayment is available in different types. If you’re having a new roof installed this season, you may consult a trusted roofing professional like Home Pro Exteriors, Inc. to help you choose the right underlayment for it. Your available options may include:
It’s important to note that most of the advancements that benefit current roof replacements did not exist or weren’t required by code 25 plus years ago so older homes often lack adequate protection against ice dams.
