  Of several contractors, they gave the best price and proposed quality. Some of it was hard and tedious which other contractors were reluctant to do. When they found the job would be more work than they expected, the two owner brothers … More joined the crew to work 2 long days and get the job done on time. Without charging, they used some upgraded materials and needed lumber because they had leftovers on hand. Rotting wood they replaced was due to roof work done by past contractors who weren't roofers. Overall, excellent competence and communication. They also provide digital photo documentation to the customer. Finally, the price came in below the estimate.

  We would highly recommend Kornerstone Roofing for any roofing work that you need. They were prompt and responsive from the start, even calling en-route to the job as requested. Estimates involved two problem areas with leaks and structural … More damage - near a chimney, and where an asphalt roof dovetailed into a metal roof. The estimator spent time to consider and explain our options, even consulting back with the home office while on the roof. Work was completed efficiently - they stayed within the estimate costs. Kornerstone has both solid experience and complete technical knowledge of products and to help consumers. All steps were explained to us in advance. We couldn't be happier with the outcome. We are proud of their work - and the roofs no longer leak!

They were accessible, responsive and punctual.After recent experiences with contractors, dealing with Kornerstone was a breath of fresh air.

  The Kornerstone roofing team is highly skilled, and they care about their work. Serge and his team were able complete our roof in just a day. Rain wasn't on the forecast either, but when showers did come the team was prepared. They … More were able to replace some T1-11 siding, some trim, as well as our skylights. They even came back to replace some shingles after I spilled paint all over the roof. Highly recommend these guys. They're friendly, professional, and just overall a company filled with good people.

  Look no further than Kornerstone for your roofing needs!! They are professional, reliable, respectful, and hardworking. Sergey is very knowledgeable in discussing options for your home with competitive pricing. They replaced my old, crooked … More metal roof with a beautiful new standing seam roof. They also rebuilt part of my chimney, replaced the porch roof and did some beautiful finish work. Attention is given to every detail. I highly recommend them!

  After the were contacted to look at the roof and give an estimate for the necessary repairs they were onsite in a timely manner. On the day they were originally scheduled to make the repairs it was raining very hard and the said they would … More be back as soon as possible. Two days later they came and made the repairs in the process they discovered some additional needs when the old roofing was removed. They replaced some sheeting that was water damaged. They also inspected the entire roof and made some minor repairs at no extra charge. The repair they made blended in to the existing roof so well you could not tell a repair had been made.I would recommend them to others.

  Mike came by to check out some water staining around my bathroom vent. He checked out my attic access, went up on the roof to look for issues, and recommended a battle plan to fix the problem! Thank you so much!
