"King Quality Construction is exactly what they are. Very professional. EASY TO WORK WITH AND KIND. Whenever we need additional work on our home that can be done by King Qaulity Construction, they will be called. This time it was replacing shingles and improper work done by the original roofer. They did the moss removal and gutters cleaning. We had neighbor next to us also checked if they had time to check their roof and get a bid on gutter replacements. I recommend giving them a call. VELDA AND STAN WILSON."

"My experience with Cornerstone Roofing was an absolute disaster, and not only would I never recommend them, I would actively try to persuade friends and family to never hire this company for any roofing work.

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

Award-winning Guardian Roofing, Gutters & Insulation has been serving the Puget Sound region with quality top-of-home solutions for almost twenty years. From the first call to the final installation report to ongoing warranty protection, the family-owned and operated company has earned the trust of manufacturers, customers, and team members in the communities they serve.

"Guardian advertises a "Gentle Wash" roof cleaning/moss removal process. Nothing could be further from the truth. In reality, they use an industrial strength air compressor and hire inexperienced, poorly trained, incompetent non-English speaking employees to perform this work. The result: While under a three (3) year contract, Guardian has destroyed my GAF 50 year guaranteed roof by shredding and removing the protective granules down to the asphalt itself. The damage is so extensive and widespread, it cannot be repaired. My roof needs to be entirely replaced at a cost of ~ $35K to $40K for a like kind of material. Guardian has attempted to mitigate the damage by inserting a new thin starter row shingle to "Hide" (not replace) the damage shingles around the entire perimeter of my home. This is an unacceptable remedy. I am awaiting for Guardian's attorney to respond to my request for compensation. Complaints also filed with BBB and the C of C."

FAQs for natural slate roofing repair projects in Sammamish, WA

If more than 30% of your slate roof is damaged, it's time to consider a full replacement. This will prevent further deterioration and avoid costly recurring repairs. A professional slate inspection (costing between $130 and $360) can confirm whether repairs are sufficient or if a full roof replacement is the better option.

A slate roof can last anywhere from 60 to 150 years, depending on factors like installation quality, regular maintenance and repairs, and local weather conditions. Compared to materials like clay and concrete, which often last around 50 years, a well-maintained slate roof offers superior longevity, durability, and long-lasting aesthetic appeal.

Yes, you can use temporary patch solutions, such as roofing cement or patchwork, to provide immediate relief for minor leaks or underlayment issues observed from inside your home. However, these provisional fixes do not replace the need for a permanent, professional exterior repair, which is necessary to ensure the long-term integrity and weather resistance of your slate roof.
