Why Your Roof Needs a Quality Roofing Underlayment
Our homes can never have enough protection. The roof underlayment, mostly invisible to an onlooker, is an added barrier or cushion that is installed directly onto the roof deck as an extra layer of protection. It is applied before the shingles are installed.
Types of Roofing Underlayment
There are three main types of roofing underlayments, including the following:
1. Asphalt-saturated felt or “felt underlayment” used to be the most popular choice for homeowners. The backing material is saturated with asphalt as a waterproofing ingredient. Although it adds stiffness to the deck of the roof, the paper has volatile compounds that dissipate over time, making the underlayment more moisture-absorbent. Exposure to heat can also accelerate its aging process.
2. Non-bitumen synthetic underlayment dominates the market. Since synthetic, the material is durable and does not attract moisture, essentially preventing the growth of mold. It is also resistant to heat damage, an upgrade from the traditional felt.
3. Rubberized asphalt is both seal-adhering and self-sealing. It is naturally flexible, making it ideal for areas experiencing volatile climates.
Benefits of Roofing Underlayment
The underlayment does not only repel water, it also provides extra weather protection in case harsh weather conditions loosen the shingles. The roofing felt protects your deck from being exposed while you replace damaged shingles as well.
