Serge was an absolute pleasure to work with , I had a leak in my 4 yr old roof ( unbelievable) I contacted Serge and a day later he was here to investigate the leak , he identified it , gave me the price ( I had other opinions and prices ) he was actually lower than the rest, he scheduled me for a week later , he and his team showed up on time and made the repair and my â leak â a week later was gone after some hard rain , they took pics every step of the way showing me the damage and how the fixed it , they were the best !!!

Glad I hired Kornerstone Roofing. Very professional and pleasant. Certainly hard workers. Completed repairs in one day under not so favorable weather circumstances. I would hire them again, no problem.

I called Serge at Kornerstone Roofing about repair of my roof due to wind blown damage. He arrived at the scheduled time and performed the repair in an efficient and professional manner. I will remember Kornerstone Roofing when it is time to replace my roof.

Prompt, professional and gave me feed back the entire job. Job became a little more involved and they handled it smoothly. Definitely recommend this company. Contacted them on Wednesday, got quote on Thursday, and following Tuesday did the job. Roof looks great, doesn't leak anymore and they also fixed missing weatherstriping around two windows causing the leak.

The original estimate/quote was honored even though the project required additional labor. The result looks really good.

We had a power vent fan replaced on our roof which was a small job. They scheduled and did the job within two weeks. They were most efficient and cleaned up after themselves. They even cleaned a side vent and some branches that had fallen on the roof a while ago at no additional charge.

The work done was excellent. Sergey contacted me almost immediately and came out the next day to tarp our roof and give us an fair and resonable estimate. He is very honest and trustworthy! He is also very good at keeping in touch throughout the process and responds very quickly to any communications. I appreciate that they were able to get our project completed so quickly. It was about 2 weeks between the estimate and having the work completed. He and the others were very efficient, thorough and the site cleanup was excellent. I highly recommend them and plan to hire them for another project in the very near future.
