"I asked Anthony to come back to redo a section of the driveway repair. I paid him for the work twice even though his contract said he guaranteed the work for several years. He came back and made it worse. For over a month he said he would come back and fix it, but his truck and equipment were not working. He then said he would send a guy out to put a temporary sealer on before the heavy rain came. He did not. I would not hire him again. He has said he would come back in the spring and redo it at his cost. If he does I'll write a new review. Don't hire this guy."

"Geo came and gave me an estimate on 3 porch post and a beam and sent a contract that defined what needed to be done. Talked to the subcontractors who weren't aware of the conditions or wheather they needed to install post brackets or any other procedures. The subcontractors talked to me about the need to replace concrete surrounding post and I told them, yes replace. Later I reazlized they hadn't neither caulked nor replace necesary concrete. From what I saw, they probably used the wrong type of post brackets for my particular situation. Somebody from Roof4Life needs to check and verify project is done correctly before they let subcontractors leave. They are the experts not me."

We are a small family owned business with 40-45 employees currently, we do not use sub contractors except when installing electrical attic fans or opening skylights. We require full payment of your bill once your job is complete to your satisfaction. We provide full release of liens from our suppliers to you at time of final payment. We accept check, Visa, MC and have Same As Cash option and long term financing up to 10 years.

"With many roofing companies as possible options for our roof replacement selecting a contractor can be challenging. Patriot Roofing performed all aspects of the project flawlessly. Communication was great all the way through, I really liked the text message updates. The crews were very polite, a pleasure to have around, I mean they all really were great! As a contractor in a previous life, I seem to pick things apart, or so I'm told, I tried but there really was nothing to pick apart. Price is always a concern but, this levels out as well and we really feel that the work performed coupled with the overall experience was well worth it. Patriot Roofing met and exceeded all of our expectations."

FAQs for roof sealant application projects in Seattle, 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.
