Types of Roofing Underlayment
Roofing services will install underlayment beneath your shingles in order to more thoroughly seal your home from the outdoors. There are a variety of underlayments to choose from. This video explains a few so you can choose the best option for your home.
As stated above, underlayment serves as a second line of protection beneath the shingles and above the roofing template. Asphalt underlayment is made out of lead pulp and other materials. It’s coated with asphalt to help get shed water off of the material. This underlayment is going out of fashion, recently.
Instead, most roofing services use synthetic felt. This material is a polypropylene. It’s more flexible and durable. It’s much stronger and more immune to punctures compared to the asphalt felt.
There are more specific underlayments, like ice and water shield. This underlayment is used in specific areas of the roof that are more vulnerable to leaks. This includes any joints in the middle of peaks and valleys on the roof, the edges, and flashing around chimneys and pipes.
Conversely, there is underlayment made specifically for high temperature climates. This will prevent peeling underneath the shingles. For more information on the different types of underlayments, check out the video in the link above.
