A Quick Guide to Choosing the Right Underlayment to Protect Your Roof
Roofing is about more than choosing the right shingles. One of the most critical supporting components is the underlayment.
It's the material sitting on top of the roof deck that serves as a barrier. Its primary purpose is to be the second layer of protection and prevent moisture penetration should it go under the shingles.
There are three main categories of roofing underlayment, each with its own set of advantages and disadvantages.
Asphalt-saturated felt
Asphalt-saturated felt is one of the oldest forms of roof underlayment. Some roofing specialists call it felt or tar paper because it's organic paper saturated in asphalt.
With this underlayment type, homeowners can expect water-resistant but not complete waterproofing. Standard felt paper is available in two varieties, 15-pound or 30-pound per hundred square feet.
Asphalt-saturated felt is typically fastened with staples, but roofing specialists might use plastic wind strips to prevent tearing in windy areas.
Rubberized asphalt
Homeowners who insist on waterproofing their roofs will benefit from rubberized asphalt underlayment. It's completely waterproof since it consists of rubber polymers and asphalt.
In rainy and cold regions, this is typically the recommended underlayment. Rubberized asphalt comes with self-adhesive with a protected peel-off membrane.
Furthermore, some types of rubberized asphalt underlayment feature polyester film that prevents penetration of moisture. The only major drawback of this type of underlayment is the cost.
Synthetic underlayment
Non-bitumen synthetic underlayment is the go-to option for many modern homes. It's lightweight yet super-efficient and durable.
Plus, synthetic underlayment is non-skid in design. If you're worried about moisture build-up and mold or fungi growth, synthetic underlayment is the top choice because it provides an impressive moisture barrier.
It's also incredibly resistant to UV damage. However, there is one problem that homeowners might have with synthetic underlayment. It could void a warranty on other types of roof coverings, such as asphalt shingles.
What are the benefits of roof underlayment?
Roof underlayment is essential, but according to many roofing experts, it's not always required. Still, most homeowners opt for it anyway.
First, there's the curb appeal. Undoubtedly, the shingles will have an even and uniform appearance and provide clean aesthetics.
When the shingles begin to crack, which they will, roof underlayment provides a moisture barrier and weather protection.
All types of underlayments protect the roof deck and deliver another layer of insulation that will positively impact your utility bill.
Get peace of mind with the right roof underlayment
When it comes to roof underlayment, homeowners have options. The most affordable and popular option is the asphalt-saturated felt, but perhaps that's not the best option for rainy and cold areas.
Rubberized asphalt has many benefits at the cost of being a bit pricey. On the other hand, synthetic underlayment offers the protection and durability you have the right to expect. Ensure that you talk to a roofing specialist who can help with your decision-making.
