Dowd roofing is an incredible roofing company! The owner, Gary is very professional & honest. He helped me throughout the whole roofing process from roofing selection to the color, & he returned my calls promptly when I had a question or concern.  The whole experience of putting on a roof was done with ease & comfort because I knew, I had a professional company.


His crew was just as terrific! They cleaned up each day & were very respectful. I felt like the job they did on my roof was like they were doing their own home. Just exceptional workmanship!


I even had a neighbor come by & say that I picked the best roofing company in the area. I would highly recommend them to anyone!

Gary Dowd has always done a great job. I'm a Realtor and refer him to all my clients with roofing needs. He has also handled my personal residence and did terrific work. I would highly recommend him. Thanks for your great work Gary!

Awesome! I found my roofer. Ceiling leaking from the last massive rain. He gave me a time for the next business day. He came out and let me explain where the leak inside and where I thought the leak was coming form our tile roof. He went and looked and gave me a rate. An excellent rate. He setup a worker for the next morning. His man arrived on time and got to work and fixed not only the shifted tile but went extra mile to clean up a couple other areas. I was impressed. We are thinking of getting the whole roof redone. If we dio we will definitely go with this company!! It's difficult to find someone who will do a good job and will work hard. Thank you Dowd Roofing!

Gary Dowd (the owner) knows his business. He was punctual in arriving to give estimate. His crew was just as punctual, and worked steady throughout the 3 day plus job. Good crew, very skilled and knowledgeable. For those folks looking for a roofing company that does it right, they should seriously consider Dowd Roofing.

I called O'Dowd Roofing to give me an overall review of my roof as I have had some shingles sliding off. They arrived and took a look at the portion of the roof. They had concerns with the roof material and provided me with instructions on how to look into contacting the manufacturer of the roof. Unfortunately, the builder has been unresponsive in returning my calls or letters. O'Dowd Roofing said they would send back another employee by week's end.. This employee arrived on the date they said he would obtained and measured our roof so that a quote could be given to us. I received the quote within a few days. I believe the quote was reasonable and it was to have a complete tear off and reinstall of my composite roof. I do have a sleep pitched roof. When all was said and done I chose to repair just the slipping shingles to get through this coming winter as I needed more time to save money to pay for the roof upfront. I  enjoyed my experience with O'Dowd Roofing and I am certain I will contact them in the near future to have the roof replaced.

Communication and coordination were great. At my request, they scheduled around my work schedule several times due to bad weather. There's a person who got to the house and did a quick repair before it rained but didn't ask for any payment until they came back a month later and were able to finish the job. RECOMMENDED.

I needed repair work done on my tile roof, Gary was prompt for both the estimate and work. He is very professional, and even though my needs were repair only. I was treated like I was getting a new roof. I highly recommend Dowd Roofing and would certainly use them again.

They were quick and efficient.

The job was completed in 1.5 days.

They were very professional and showed me all the areas (rotted plywood) that needed extra work.

Gary's crew started on Monday and finished on Saturday. It was a tough job and they all performed well. The quote amount and job length was right on target. I would definitely recommend his company to others.
