dallen+and+sons+roofing+siding“When you come right down to it, the roofing products offered by contractors are all pretty comparable in quality, longevity, and price. A genuine difference in how well a roof performs, however, depends on the experience, technique, and caring of your roofing company.” – Dennis Allen

It went very well! Their prices are fine (not the cheapest but not out-of-line with other contractors) but become a real deal when considering the professional quality of the work. We are very happy with the results, and we’ve received a lot of compliments from people in the neighborhood on how it looks. I must also note that their responsiveness and professionalism deserve a grade higher than an A. They respond to emails, texts, and voicemails. They get back to you and always make sure you know what’s going on. That, combined with the high quality of the work, makes me recommend them highly. It takes a lot to impress me when it comes to home improvement and contractors, but they exceeded my expectations.

(Description of work:  Siding and gutters were installed on the front of the house and some roof repair.)

Can’t say enough about this contractor very professional and informative,
explaining everything in detail on the work they will perform. Arrived on the date and time agreed upon. The crew was great very courteous and respectful of me and my property. The roof on house and garage look beautiful the contractor even put roofing on my little shed which was not even in the plan. Highly recommend D Allen and Sons you will not be disappointed.
