Homeowners know that keeping their roofs in good condition is critical when it comes to preventing water damage. What many homeowners might not realize is that a roofing system consists of several layers of material.
Your asphalt shingles, tiles, or shake roofing materials are only one of the layers that cover your home. The first layer in any quality roofing system is known as the underlayment. Roofing contractors often refer to an underlayment as felt paper because of the felt-like texture of underlayment products.
This felt paper serves as the primary product when it comes to waterproofing your home's roof because it acts as the last barrier against water infiltration. Understanding the benefits underlayment provides will help you more effectively select the underlayment best suited to meet your roofing needs.
Protection Against Deterioration
In addition to acting as a waterproof barrier for your home, underlayment plays an important role in protecting your other roofing materials against deterioration.
The wood that is used for roof decking can contain trace amounts of sap. This sap has the potential to seep through the roof decking when outdoor temperatures rise. Sap can be detrimental to shingles, tiles, or shake roofing. By serving as a barrier between the roof decking and other roofing materials, the underlayment prevents sap-related deterioration.
Another problem that you might face during periods of hot weather is the melting of the asphalt shingles on your roof. If temperatures get high enough, shingles can actually melt into the roof decking below. An underlayment separates the shingles from the roof decking and allows for the easy removal or repair of any damaged shingles.
Reduced Noise Pollution
Another important reason you should include an underlayment underneath your home's roofing materials is the noise-dampening ability of felt paper. You want your home to be a peaceful and quiet place to spend time.
Wind, rain, and other outdoor elements that come into contact with your roofing system can generate noise that will disrupt the silence in your home. Felt paper can act as a buffer between these sounds and your home's interior. The underlayment absorbs some of the noise before it penetrates your roofing system.
If you live in a particularly noisy area, then you can opt to install a thicker underlayment product to help further reduce noise pollution within your home.
Temporary Storm Protection
Severe storms have the potential to wreak havoc on the integrity of your roofing system. High winds can blow shingles off your roof, and large hailstones have the potential to damage individual tiles and shake roofing materials. In the event that your roof does sustain damage during a storm, your home will be vulnerable to water infiltration.
When you have the right underlayment installed beneath your roofing materials, you can enjoy temporary protection against water damage during a storm. The underlayment will prevent water that enters through areas where roofing materials are missing or damaged from saturating your roof decking or sheathing. This temporary protection prevents water from leaking into your home and causing further damage to your residence.
Although underlayment is not designed to withstand long-term exposure to the elements, it can be counted on to provide temporary protection until you can replace roofing materials damaged in a storm.
If you want your home's roofing system to perform efficiently, you need to have the right underlayment installed. Upgrading your existing underlayment to a thicker felt or a synthetic polymer product will help you provide maximum protection for your home against water damage.
