The underlayment is the thin membrane that goes onto your roof sheathing before the tiles are installed. Home roofing contractors use these all the time, except on special cases. That’s because the underlayment fulfills a variety of purposes that go toward protecting your roof. We’ve listed some of these here.
1. Keeps You Dry
It may come as a surprise to many of you, but your roof isn’t waterproof. The shingles that you install on top of your home are usually not made of waterproof materials. They are water-resistant, but if you want your roof to be waterproof, then you look to your underlayment. This material is placed underneath your shingles, which is the single most waterproof element of your roof. It doesn’t restrict water vapor, but liquid will not be able to penetrate through this barrier.
2. Protects From Fire
If you’re installing a wood roof or if your rafters and sheathing are made of wood, then a large part of your roof is not fire-resistant. But, don’t worry; a special kind of underlayment is typically used by your roofing construction company to help ward your roof against fire. This special underlayment is fire-resistant, which can protect you and your home by preventing fires from spreading.
3. Acts as an Emergency Roof
Sometimes, you need to delay the installation of the shingles for some reason. Alternately, inclement weather may have stripped your roof of some of its roof tiles. The great thing about the underlayment is that it won’t tear off easily. The membrane is attached snugly to your roof either via adhesives or plastic cap pins, and while it won’t last long as a temporary roof, it will do in a pinch until professional roofers can lend you a hand.
