SWR Underlayments

Protection From Potential Water Damage

A secondary water resistance (SWR) underlayment is the first line of protection from water damage within your home. It is installed directly to the plywood roof deck and is a self-adhering polymer-modified bitumen roofing underlayment (thin rubber sheets with peel and stick underside).

When this underlayment is properly installed, it will provide protection from even the heaviest of Florida downpours.

At King Roofing Service Inc, we only use top brand-name products for our SWR underlayment applications. Thanks to our decades of experience serving Naples, FL, we know exactly what it takes to protect your home from Mother Nature. Over the years, we've seen it all!

Upgrade to SWR Underlayment

Homes with roofs installed prior to 2007 will most likely not have an SWR underlayment installed since they were only introduced and became a new code and application method in Florida with the 2007 building code revision.

Keep in mind that roofing felt or similar paper-based products (30 lb/90 lb hot mop systems) are not acceptable for secondary water resistance. Hot mop applied felt is often used under tile roofs as the primary water resistance layer and is often confused with secondary water resistance products.
