Building-envelope waterproofing, deck and below-grade systems, and professional painting for homes and projects across the Flathead.
A continuous membrane applied right over the exterior sheathing, with none of the laps and seams of conventional house wrap.
Air & Water Barriers →Waterproof systems for walk decks, roof decks, balconies, and other exposed surfaces with living or finished space below.
Deck Waterproofing →Foundation and below-grade assemblies protected before they're buried and hard to get back to.
Below-Grade →Interior and exterior painting for homes and projects, prepped and coated to hold up to Montana exposure.
Painting →Fluid-Applied Building Envelope
Ridgeline installs PROSOCO R-GUARD® Cat 5™ directly over exterior sheathing: one continuous air and water barrier around the structure.
Rolled or sprayed over the sheathing instead of piecing together house wrap.
Windows, doors, penetrations, and transitions tie into the same system.
Made for demanding wind and rain exposure, and goes on damp substrates.
Cat 5 is our preferred system; other fluid-applied air and water barriers are available by project specification.
From the Field
Most of a waterproofing job gets covered up once the finished surface goes on. These are the prep, detailing, and systems that end up behind the walls and under the decks.
