I specifically waited to write this review until a few months after the job to make sure everything held up. It has. No callbacks, no issues. The work was done right the first time.
Nathan Q.

We appreciate you taking the time to review our roofing services in Seattle. Your feedback means a lot to our team!
Yolanda N.
Had them back for an annual check and they found a small issue I never would have caught on my own. Preventive maintenance that saved me probably a thousand dollars down the road.

Jasmine T.
What started as a small repair turned into us hiring them for three additional projects. Not because they upsold us but because the quality of the first job was so good we wanted more.
Tony M.
They showed up on time, diagnosed the issue quickly, and had everything fixed within a couple hours. Upfront about pricing with no surprise charges. This is how it should be done.
Response from K Single Corp

We had an emergency situation and they squeezed us in same day. Not only did they fix the immediate problem but they caught another issue we did not even know about. Saved us money in the long run.
