How much do roof underlayments cost?

A sturdy and reliable roof is uncompromisable for any homeowner, but do you know what it takes to make a roof that can stand through the year-round ferocious weather conditions?

When it comes to roofing, there is so much more to it than what meets the eye. Roofing underlayments are installed on your roof deck as the last resort to protect your house from precipitation and leakages.

A Brief Guide to Roof Underlayments

There are a couple of variations to roofing underlayments, each type having its distinct benefits and purposes.

Felt underlayment

When it comes to roofing underlayments, felt has been the go-to option for a very long time, partly because of its affordability. However, it is now being superseded by other kinds.

Felt paper or tar paper is made up of a mat saturated with asphalt to provide water resistance. Available in 2 standard weights, commonly called No.15 and No. 30 felt. The No.30 felt is more robust and perhaps the best option for a longer-lasting roof.

Felt underlayments strengthen the roofing material on top, providing a sturdy roof. However, felt underlayment roofings are prone to moisture and can also be deteriorated by intense UV exposure.

Costing around $5 per square foot, it is a cost-effective option.

To conclude, felt underlayments remain to be the conventional choice among homeowners providing good utility. However, if you have a flexible budget, you can get more value from other types.

Synthetic underlayments

For the past few years, synthetic underlayments have been getting very popular among homeowners. The popularity shouldn’t come as a surprise, considering the durability and versatility they offer.

This underlayment is also saturated with asphalt, plus it includes fiberglass coating. These coatings make synthetic underlayments tear-proof as well as moisture-proof. Due to its high functionality, most contractors and homeowners prefer them over other roofing materials.

Unlike felt underlayments, they are designed to be lightweight. After all, you don’t want to put excess weight on your roof.

On the flip side, one major downside to synthetic underlayments is their cost. On top of that, it is pretty challenging to install synthetic underlayment roofing, and it takes way more time.

The average cost of synthetic underlayment lies around $10 per square foot. That’s almost twice the cost of felt underlayments, but considering the value synthetic underlayments provide, the price is well justified.

Peel and stick

A self-adhesive underlayment, optimum for hot and humid weather conditions. Made up of rubberized polymers, “peel and stick” underlayments are flexible and provide more resistance against harsh weather conditions.

Overall, it is the most suitable underlayment roofing material; from installation to maintenance, a “peel and stick” underlayment requires the least effort.

Installing “peel and stick” underlayments do not require nailing individual patches and gluing them to the roof. Thanks to the adhesives, the underlayment sticks to the roof itself.

The overall cost of a peel and stick underlayment varies considerably based on a couple of factors. Still, there are almost no installation charges to them compared to synthetic or felt underlayments.

Ice and water shield

Also referred to as an ice and water protector, it is also a self-adhesive underlayment roofing. The ice and water shield is specifically designed to provide maximum protection from precipitation and moisture.

Furthermore, ice and water shield is composed of modified bitumen, the ice and water shield develops a watertight seal around roof shingles. This makes it impossible for water to seep in and also eliminates the likelihood of any leakage.

For colder regions, ice and water shields are crucial for protecting against ice dams. Moreover, hurricanes and thunderstorms with precipitation prove catastrophic for most roofing underlayments. Whereas with the ice and water shield, you are protected from all such dangers.

However, it is pretty expensive to belong to the higher tier underlayment type than the other options. For regions that face unusual precipitation levels yearly, the ice and water shield is worth investing in.

Why are roofing underlayments important?

It might seem irrelevant to put a second layer of roofing under shingles, but underlayments serve a crucial purpose.

Unlike shingles, underlayments are installed side by side, so there’s no overlapping. This guarantees a sturdy and impenetrable roof.

Moreover, having underlayments installed on your roof increases the value of your real estate. After all, everyone wishes to have a reliable roof over their head.

How roofing underlayment works
