My mom used Alfa roofing to replace her hail damaged roof and they were prompt, fairly priced and the communication was great. They made the process very smooth and she is very happy with the results. Thank you

We had our roof replaced recently by Alfa Roofing and Siding and they are an excellent roofing company that I would be happy to recommend. It was the first time we have gone through the re-roofing process and we feel fortunate to have hired them for the job. The new roof looks great! They were very professional, responsible, and knowledgeable. Not to mention they were courteous, accommodating and always there to answer questions. In addition to our general roofing job they also took care of some structural issues we had that other roofing companies weren't able to. They've been around a long time and there’s a reason.

We had major hail damage from a storm last year. We had an original cedar roof from 1992. Our Insurance company recommended a company to fix the roof, siding, soffits and eavestrough. I contacted this company and asked them for a quote to replace the roof with asphalt roofing. The owner came out and literally spent 20 minutes looking at the job. A week later he emailed me the quote. I was not convinced he seemed new to this game or not really competent. There was a lot of damage to our house and looking at the house for 20 minutes didn't seem to cut it. I happened to run into Lynn and asked him to give me a second quote. He came himself and spent hours looking at the house to the point that I went out to check on him, he was just being very thorough. His price came in $1000.00 dollars less with a better quality shingle. They started the job in late October and Lynn told me they would be 3 days starting on a Monday. They were forecasting heavy snow by the Thursday. I called Lynn and he told me not to worry it would be done on time. 2463 square foot house with cedar to be removed and replaced. I thought 6 guys would show on the Monday. Monday 2 guys showed up. I said to the wife no way are they going to do this, 5 to 6 days maybe. When I came home from work on Thursday at 5 they were finished and cleaning up. We were amazed by the great job they did for less. Lynn and their crew are old school stand up guys. I would not call anyone else and would encourage anyone to just call them. They will be coming back in the spring to finish the soffits and siding.For the record I'm not related to anyone at Alpha Roofing I'm simply a very impressed & satisfied customer.Trevor
