We are extremely happy with the whole experience! Our house is a 1950s rambler (about 1600 sq ft) with the original wood planks over the main area and plywood sheathing over an extension. The previous roof shingles were about 25 years old. Tom Keehn came out to the house to evaluate the job and was very helpful in explaining what they would do step by step. We were very impressed with all of the details that he provided and with the literature that he left with us. The other companies that we contacted did not go into as much detail. The price was extremely competitive and after we signed the contract, the job was scheduled very soon after. The men who did the work are very professional, courteous, and highly skilled! After they removed the old shingles, they found some problem areas and were able to solve every problem - including replacing wood in some awkward areas, and a very rusty metal chimney stack. They conscientiously checked every single board on the roof to make sure it was still sound and they only replaced those areas that were rotten. Then they made sure that all of the original boards were securely attached to the rafters - adding extra nails if necessary. Then several layers were placed over the wood - my neighbor who watched the entire process from a higher vantage point was incredibly impressed with how well the roof was sealed before the new shingles were put on. The men cleaned up throughout the process and by the end of the job - everything was gorgeous - the roof is beautiful, the new flashing is better than it ever was, etc. This is an incredible company! We highly, highly recommend them!

Tom was extremely nice and easy to work with. He promptly came out to give us an estimate and gave us some great recommendations. His team was extremely responsive along the way and worked well with us to accommodate our schedule and make late adjustments. The team was really respectful and worked really **** ** replacing our roof and gutters. The roof looks amazing and they did a meticulous job cleaning. They swept through the area two days in a row and cleaned and wiped down our back porch that got a little dirty. Certified was extremely easy to work with and I would highly recommend them.

The job went exceptionally well! Certified allowed a variance to the original schedule due to unplanned surgery. On the appointed date, the crew arrived on time and went about their work expeditiously and efficiently. They stayed on site for 12 hours finishing everything except one cap piece. The crew chief showed up the next morning and completed the work in less than an hour. Would hire Certified again and recommend same to others.
