The underlayment is an essential part of any roofing system because it provides an extra layer of protection between the deck and the roof shingles. It is also the last line of defense before roof leaks or moisture problems enter your home.
These are the three basic types of underlayment:
Asphalt Saturated Felt
Asphalt saturated felt underlayment is typically made from organic fibers. There are two types of thickness: 15 pound and 30 pound felt. The former is more popular in high humidity locations while the latter is more resistant to damage during installation. Asphalt saturated felt is great for preventing moisture from penetrating the roof deck and causing further damage inside the roofing system.
You can easily formulate the right roof underlayment for your home with rubberized asphalt. It can be manufactured to excel in particular areas like weather and skid resistance. Rubberized asphalt can be placed underneath metal roofs because it can resist up to 250 degrees of heat. An experienced roofing contractor would generally recommend this option for houses in high-temperature areas.
Non-bitumen synthetic underlayment is known for being light-weight and highly resistant to algae and mold growth. Unlike the first two underlayment types, this does not absorb moisture; instead, it serves as a barrier before moisture can damage the inside of the roofing system.
