Installing a New Roof? Pay Attention to the Underlayment

A new roof can be one of the most costly investments a homeowner can make. The longer you own your house, the more likely it is that you will need to replace your roof. When it’s time to replace your roof, pay particular attention to the roofing underlayment. check the link to know more.

Your roof’s covering, whether it’s asphalt shingles, metal, wood shake, or another material, serves only as a water-shedding device. Roof coverings aren’t water-resistant! Rain can be driven up under shingles by strong winds. Water will back up on the roof and seep under the covering due to ice dams. Storms may also damage the primary roof covering, allowing water to get to the deck and into the building due to flying debris or hail.

The purpose of the roofing underlayment is twofold. For starters, it serves as a temporary water-shedding cover for the roof until new shingles are added. Once the primary roofing is in place, the underlayment serves as the home’s second line of protection against water infiltration. This work should be performed by a good roofing underlayment for the entire life of the primary roof covering.

For several years, roofers preferred asphalt saturated felt as a roofing underlayment. Many of them still use it today, mostly because it is the most cost-effective choice. Felts today are not the same as they were 10 or 15 years ago. They contain much less asphalt today than they ever did. Over the last ten years, the price of asphalt has risen, and felt manufacturers have reduced the amount of asphalt in their products to keep costs down. While the price remained low, the quality significantly deteriorated.

The most basic of underlayments, 15 or 30 pound roofing felt, can only be used if you don’t have the funds to pay for a better underlayment or if you just don’t care. It is easily torn, wrinkles when wet, and does not last the entire life of the roof covering. Wet felt wrinkles can also pass through asphalt shingles, giving your roof a wrinkled look.

As a homeowner, this is one of the largest and most significant expenses. You have no shelter from the weather for your family or possessions if you don’t have a roof. Purchase and instal the best roof covering possible, as well as a high-quality synthetic roofing underlayment such as Grace Tri-Flex. Your roof will last longer and have a better appearance.
