Client Testimonials

"Roofing Remodel - our re-roofing replacement job came out perfect! Chris and his team were very professional and they came when we expected to do our roof which was a big project. The team tarped the house and cleaned everything, we did not have to worry. We would strongly recommend Add On Construction for your home improvement projects. We are planning on going with Add On Construction for our future project needs. We’ll done Chris and team! Thanks"


"I was looking for someone to repair some loose roofing shingles before winter. Chris came the same day I contacted him, provided a quote that was lower than others I had received, and was able to complete the job that afternoon! He identified additional spots that needed repair and took care of those as well. He was very professional, knowledgeable and did the work for a reasonable price. I would highly recommend Addon Construction!"


"Addon performed roof repair (roof caps) on my home. Chris visited several times to review the job and go over all the details. Chris provided a verbal quote initially but followed up with a formal quote via email within an hour. Chris was highly professional and we felt most comfortable selecting Addon for the job. Once the job was started it was completed within a few hours. Professional cleanup was completed and all shingle pieces and old nails were removed. I would definitely recommend Addon and will be calling them again for future jobs."
