Harrison & Sons Roofing Reviews
I was seeking a "tear down (old shingles) and new shingle and gutters installation" for a 2,400sf house. I spoke with Mrs Harrison, and she said that they would inspect the house, prepare a quote, and e-mail the quote. Within 2 days, I received my quote.I waited 4 days to receive quotes from the other companies, and based on the reputations and quoted costs from each roofing company, I selected Harrison & Sons Roofing.Within a couple of days as agreed, the Harrison crew arrived and started working. They were very careful so as to cover all the existing shrubs, flowers and air conditioner. They had all the old shingles stripped down by mid afternoon. The new shingles were delivered and distributed across the roof.Early next morning, the crew started laying down the roofing paper and shingles. The installation of the whole roof and gutters was completed by the end of the second day. The workmen were very polite, and demonstrated a high level of professional and experienced craftsmanship as they worked.I was very pleased with the whole experience from writing the contract, to hammering the last nail that finished the job.Based on my experience with the Harrison's, I then contracted with them to roof my mother's house.I highly recommend Harrison & Sons for any of your roofing needs.
March 03 · Jim CarlinHarrison & Sons has done a great job maintaining our very pitched main roof and flat roof on our porch, both asphalt, for the last 9.5 years. We will use them when it is time to for a new roof.
January 22 · Kate Mueller"I have had several roofs replaced by Harrison and Sons and they did an excellent job every time. (My roof, our pool house roof, and a friends roof). The pricing was very competitive as well. I highly recommend Harrison and Sons! "
January 26 · Steve WoollardOn February 12 the Harrison group was notified that there was a lot of water coming into the warehouse where I work. - well, It's been raining and it is still not fixed. Today March 1 - Hundreds of dollars of product have been damaged do to their lack of completing this job which to me is quite simple - (fixing gutter boards so the water doesn't go behind it so it doesn't go down the wall and into the garage door and into the warehouse) - Harrison's first response to the issue was that the roof was dry - well then the water is magically going down the wall into the warehouse. I would not recommend this roofer for business or for personal home. Owner of the building has been given the run around every time he calls to get this work done and given excuses that have nothing to do with fixing the problem. :(
March 01 · Elizabeth AtterberryExcellent response and work! We were collecting water in the attic and were afraid that we would need a roof replacement. H T Harrison responded promptly and professionally. The inspection and estimate was done by an actual roofer and he seemed to know his stuff. We were impressed that he gave us two estimates, one for immediate repairs and one for replacement, which we appreciated. He assured us that the repairs would hold us for awhile and did not pressure us to go with the whole replacement. The work was done in several hours and the yard left clean. The repairs were well-matched and done so neatly that its hard to find the new areas. The roof has stopped leaking! When the time comes for replacement, we fully intend to have H T Harrison back to do the work.
