You don’t have to be a professional roofing contractor to know that all components of a roof are essential. While the shingles that make up its exterior are the most visible, it’s the invisible parts of a roof that help keep it in good shape whatever the season or weather might be. One of these components is the underlayment.
The underlayment is a protective sheet that covers the plywood roof deck and serves as a barrier between the shingles and the assembly that holds the roof together. Read on as our skilled contractors at Northwest Construction give you an overview of the importance of this roofing component.
The Purpose of the Underlayment
While your shingles and gutters keep unwanted rainwater away from the vulnerable wood structures of a roof, they are far from perfect. Some amount of water can still penetrate the shingles and damage the sheathing and rafters. Additionally, constant exposure to UV rays can “melt” the asphalt shingles into the roof deck. This is a problem that could be potentially expensive to resolve. A good underlayment prevents all these problems from occurring in the first place and helps protect your entire roofing system from further damage.
Felt sounds like something out of an arts and crafts shop but roofing felt is different. It’s designed to be tougher and more resistant to many of the common problems that roofs face everyday. Even though its surface is slippery, it’s actually saturated with bitumen making it more resistant to water. Felt is an inexpensive underlayment option.
On the other end of the spectrum is synthetic underlayment. This material is generally better than felt at preventing costly roof repair jobs due to water damage and other problems. However, its higher quality comes at a much higher price.
