Roofs are made of many layers. One of these components is the underlayment. A home improvement contractor may suggest that underlayment isn’t always necessary, but experts note it should be applied to low-sloped roofs and specific high water risk locations of your home. Here are more reasons why it’s still an essential feature.
- An underlayment adds another water-resistant layer to the top of your home. With it, leaks during heavy rain, high snow accumulation and severe storms can be prevented.
- An underlayment provides an extra cover of shielding should your roof become damaged or any shingles or shakes are blown away during a heavy storm. The roofing underlayment will serve as a protective barrier until actual fixes are done or the shingles have been replaced by a roof or gutter contractor
Types of Roof Underlayment
- Non-Bitumen Synthetic Underlayment
Thanks to its superior waterproofing characteristics, most residential and commercial roofing installation contractors select non-bitumen synthetic underlayment.
- Asphalt-Saturated Felt Underlayment
This is the cheapest option. Asphalt-saturated felt underlayment is manufactured by waterproofing felt paper. It comes in 15 and 30 pound weights. The latter is firmer and less prone to breakage during installation.
- Rubberized Asphalt Underlayment
If you want to protect your roof against moisture damage, this is the most expensive alternative. In addition to being waterproof, rubberized asphalt underlayment is made up of asphalt and rubber polymer.
