Getting A New Roof Installed? Why Install A New Underlay Membrane At The Same Time

If you're going to have a new roof installed, now's the time to take a close look at the underlay membrane. If the roof deck is still in good shape, you might not think you need a new underlay membrane. That's not the case though. The underlay membrane provides protection for your entire roof structure. Over time, the membrane can wear out. When it does, you need to have a new membrane installed. The best time to do that is when you're having new shingles installed on the roof. Here are four reasons to have a new underlay membrane installed along with your new shingles. 

Prevent Water Damage

If you're ready to have a new roof installed on your home, take the extra steps to prevent water damage. You might think that new shingles provide all the water protection you need, but that's not the case. You also need the underlay membrane. The underlay membrane protects against water damage caused by rain, snow, or ice. 

Adds Roof Insulation

If you're going to invest in new shingles, this is a good time to increase the insulation for your home. Most people think that insulation goes in the walls and attic of the home. But, the underlay membrane adds another layer of insulation to the roof. The underlay membrane acts as a barrier to keep heat and cold out of the attic. As a result, your home stays at a comfortable temperature all year long. The underlay membrane also protects your shingles from damage caused by extreme temperatures. 

Protects the Deck

Now that you're having a new roof installed, it's time to think about the roof deck. The roof deck can take a lot of abuse. Without proper protection, your roof deck absorbs the heat and the cold. It can also suffer moisture damage from water exposure. If you don't take steps to protect the deck, you'll need to have it replaced the next time you have a new roof installed. You can avoid the damage and the added expense. You can have a new underlay membrane installed with your new shingles. 

Stops the Pests

If you've seen pests in your attic, you might wonder how they get there. One way is through the roof. Pests like ants and roaches crawl between the gaps in the shingles. Once they're under the shingles, they can crawl right through to the attic. This is especially true if the underlay membrane has gotten damaged. To keep pests out of the attic, replace the underlay membrane when you have your new roof installed.
