Customer Reviews

"Great decision to trust Alliance Roof and Fence with my home repairs. Colin is awesome and will see to it that the job is done right. Roger Osman was my project manager for all my work. I would highly recommend calling and asking for him. He answered all my questions and promptly returned all my calls. He made sure the job was done to my satisfaction, which is a challenge because I’m very detailed and picky. 10/10 would recommend. Give them a call."
"Roger was such a pleasure to work with. When he arrived we had been dealing with insurance and nothing seemed to be moving forward very quickly. We had damage to our roof and our vinyl siding from the wind. He came out, gave an estimate and worked with our insurance. He was very knowledgeable, professional, responsive to our questions( several times after hours) and the work was completed in a timely manner."
"Colin O'Brien (owner) and Elvis Lopez (sale representative) of Alliance roofing & Fence they are knew how to deal with insurance companies. They got my insurance to pay for my siding, all sides of the house after the adjuster estimates just for one side where is the storm damaged. And on the roof the insurance pay for three tab shingles (that was my original roof) but Alliance gave me architectural shingles. They done good work."
