Qualities to Look for in Roofing Underlayment

Larry Walty II • September 19, 2022

Underlayment is the barrier placed on your roof before the roof material itself. Its primary role is to support the roof material and protect the attic from moisture infiltration. That said, roofing underlayment must be durable and long-lasting.

Experts recommend looking for the following qualities to ensure you have the best roofing underlayment for your home.

Weather Resistance

Your local climate determines which roofing materials and underlayment you should use. Homes that typically experience moderate weather can do well with asphalt-saturated felt underlayment. But if your area is prone to severe storms, rubberized asphalt will make your roof more resistant to extreme weather.

Underlayment Material

Every roof underlayment material is different. Felt underlayment is cost-effective and offers adequate protection. Rubberized asphalt is more durable, so it has a better chance of withstanding extreme weather events. Synthetic underlayment is watertight and offers some insulating capabilities. 

Roof Material Compatibility

Each underlayment material pairs well with specific roof materials. Asphalt shingles and slate tiles work well with rubberized asphalt and asphalt-saturated felt underlayment. Meanwhile, metal roofs are usually paired with synthetic roof underlayment due to their thinness and heat-resistant properties.

Durability and Tear Resistance

Durability varies for each underlayment material. Synthetic roof underlayment is the most durable and tear-resistant. Rubberized asphalt ensures excellent waterproofing. Lastly, asphalt-saturated felt underlayment offers enough moisture protection for most properties.

If you’re still unsure of what underlayment to choose, don’t hesitate to ask your roofing contractor for advice. Ask them about the best underlayment suitable for your roof material and local environment. They may need to inspect your roof to give you appropriate recommendations.
