Underlayment, does my roof need it?

UNDERLAYMENT

December 29, 2020   |   Home Improvement, Roofing

Short answer- Yes. Your roof plays a critical part in protecting your home from the severe weather it will face throughout the year. Just like other parts of your home, your roof will require maintenance and repairs to ensure that it stays in pristine shape, but eventually, it will need to be fully replaced. Now, if it's getting past the point of repair and you believe it's time for a full replacement, there are different options to consider like; how long do you expect to continue living in the home, what type of weather do you experience in your area, and one of the most overlooked aspects of a roofing system- the underlayment.

What Is Underlayment?

Underlayment is a highly water-resistant or waterproof barrier material that will provide additional protection for your home against the elements. No matter if it's a new roof being built or an old roof is removed, the underlayment is attached directly to the roof deck, providing a sheathing layer of total water protection. If something damages the shingles or roof covering, the roof decking is still protected from water thanks to the underlayment.

In residential roofing projects in the US, there are 3 underlayment types that are most commonly used: felt soaked in asphalt, rubberized asphalt, and non-bitumen synthetic underlayment. Each of these materials can significantly increase a home’s defense against water.

Benefits of Installing Underlayment

The reason why homeowners want to install a roof underlayment is water protection.  In areas like the North East and other parts of the country that receive significant rainfall throughout the year, installing roof underlayment is practical and a necessity.  It's also a smart move to install underlayment on low-sloping roofs, even if the area you live in only receives moderate precipitation throughout an average year. Avoid costly repairs and ensure you have an underlayment, especially if your home has low-sloping roofs, which are more vulnerable to water damage if compromised.

One out of every three American Homes uses Asphalt Shingles, it's the most common roofing material used for homes in the United States because they are cost-effective and durable. But, they aren't indestructible. They are still vulnerable to damage from many sources; Severe weather, high winds, animals, and other things can damage, dislodge, or corrode shingles and leave the roof vulnerable to water damage. Underlayment acts as a final defense for a roof’s underlying structures, potentially meaning the difference between patching a few shingles and paying thousands of dollars for a roof replacement due to water damage.

Consider if Underlayment Is Right for Your Roof

If you are going to replace your roof soon or build a new home, it’s vital to consider whether underlayment is right for your property. It’s also possible to have underlayment specially configured for your home’s geometry by protecting the valleys, eaves, and various protrusions of your roof. Ultimately, not every home may need underlayment, but professionally installed roof underlayment can provide reliable moisture protection for any home.
