In my view, they were evasive and not willing to stand by their work. Beware."

Pacific Exteriors LLC is the exterior remodeling contractor you can trust for all of your siding, roofing and painting needs in the Greater Seattle and surrounding areas. We offer personal consultations, custom design services, and high-quality materials backed with best in the industry warranties to upgrade your home’s exterior and protect what matters most! Pacific Exteriors LLC is a BBB A+ business, Owens Corning Platinum, and James Hardie Master Elite company. We are a proud winner of the annual James Hardie Presidents Club Award, the last 6 years in a row.

"I’m not quite sure what is taking so long to get any updates from this company. I’ve been waiting for an update on the siding being painted, touch ups they missed to be fixed, have their interior team fix the walls their crew punched nails through the wall, broke the frame of our kitchen window, and pick up the materials that have been blocking our driveway since the start of the project. It took them three weeks from the initial pick up date I was given for their team to pick up and confirm that the honey bucket had been taken from our property. Of course I had to call them to follow up and actually get it picked up. All of this to basically summarize that if you want your siding done in a timely manner and to work with a cohesive team that values communication and their customers as much as theirs salesman Brad told us they do, then find another company aside from Pacific Exteriors."

"STOUT ROOFING just completed my new roof today on our 1100 sf. garage. It's so beautiful I just perched myself where I could stare at it for a while! The crews were amazing - so hard working, proficient, courteous and meticulous in their roofing skills as well as prep and clean up. And they even did needed extra items I hadn't asked for! The roof should have been replaced some 10 years ago and so the crews had to go the extra mile to give me another 30 years with this brand new roof. Losing my husband some 8 years ago, I work extra hard to nurture our homestead, and so it is encouraging to find a company such as Stout Roofing who comes alongside and does some of the heavy lifting! I highly recommend Stout Roofing to any home or building owner needing a new roof!"

FAQs for roof sealant application projects in Duvall, WA

A roof coating system lasts between 10 and 20 years. With a premium coating and regular maintenance—like inspections and touch-ups—your roof will stay protected against weather damage and water intrusion. This enhances its durability and preserves its structural integrity throughout its lifespan. Make sure to keep in contact with a roof coating pro so that you don’t miss regulating resealing. 

You should recoat or reseal your roof every four to six years. Maintaining a consistent recoating schedule preserves the integrity of the protective seal and prevents moisture penetration and material degradation. High-quality, built-up roof systems require this interval, and if an EPDM roof begins to leak, replacing the coating becomes necessary to restore full protection.

A roof coating can seal small cracks and stop minor water infiltration, helping to prevent roof leaks. While the coating enhances the roof’s durability and prevents early signs of leakage, it does not replace the need for full-scale repairs when substantial structural damage exists. Professional evaluation and repair are required to resolve significant water intrusion and ensure your roof retains long-lasting protection.
