"All under one roof did a fantastic job removing two layers of shingles and installing new roof. The whole team was hard working and completed the job in one day. When they were done my yard was cleaned of all debris. I highly recommend All Under one roof."

"Met with 5 different roofers for an estimate, but these guys were the most thorough, very cool technology for us to see video of our roof, inside the attack view, so we could see what was needed. Kyle, our rep, was very knowledgeable and didn't try to sell us on things we didn't need, worked to make it affordable for our options. Then Justin and the crew came and did an awesome job replacing the roof in one day. Highly recommend!"

"The workers that removed and replaced my roofs had fantastic work ethics. They did a wonderful job and left my yard nail free and debris free. I will recommend them to anyone I know that needs a roof or any other home repair."

"If we could give Mighty Dog Roofing more than five stars, we would. Their pricing was excellent, their turnaround time was lightning fast, and the communication and workmanship far exceeded our expectations. From the moment Paul came to our home to inspect our old, leaking skylight, we knew we were dealing with a company that values professionalism and integrity. The crew replaced our skylight along with the extensive rotted roof sheathing around it. They also replaced a missing shingle and sealed a vent pipe and a second skylight at no additional charge. Their communication was excellent. They provided photos and videos before, during, and after the project. Mike, the outstanding on-site supervisor, checked in with us repeatedly, answered every question, and made sure we knew exactly what was happening. He and his crew also left the place spotless when they were done. We’ve hired many contractors over the years, and this was genuinely one of the best experiences we’ve ever had."

"We got 3 roofing estimates. We made an appointment with the owner David Crasny. He showed up on time. He was the only one of the 3 roofers who got up on the roof (3 stories) to take pictures and evaluate. We received his estimate in 2 days as promised. It was detailed and thorough and gave us the option for a few extras (over fascia sealing & back porch). His price seems very fair. All roofers use GAF or equivalent shingles. He is trained and certified in GAF products. We were told by 2 roofers (we didn't ask him specifically) that we could have some shingle repairs done and can delay a new roof for 2 years. Based on his promptness and professionalism in person and in his estimate we will probably choose him when we do our new roof. We got a very low and very high estimate from other roofers. His was in the middle."

"they replaced the shingles on top of a bay window where there had been an ice dam and added underlayment. The siding on the house is pre-colored Hardie board, while doing the work two of the Hardie boards broke. They replaced the broken boards with two primed but unpainted Hardie boards . They never asked if we had more pre-colored boards in the basement. We did! I asked them to make this right by pulling off the two unpainted panels and putting in the factory painted ones - The asked for an extra 650 which seems like a lot Before the job the communication was great, lots of pictures, but they did not say Hardie board is likely to break - which would would have gotten me to point out where the spares were After the wrong boards went up they were responsive and polite but not helpful The contract that i signed said they were not responsible for painting any siding, so they were technically right but they left me on my own"

"We have been in our home for 21 years and our roof needed to be replaced. I did my due diligence and received 4 quotes from HomeAdvisor recommended roofers (Asphalt shingles not metal since we will be downsizing in 2-5 years max.) A neighbor had moved in last year and had their roof done by Exteriors Unlimited, LLC. I decided to get a 5th quote. I received quotes from 5 GAF Certified roofing companies. Four of them ranged from $13,800 to $18,000 - all with very similar terms and warranties, with some variation on the cost of replacing plywood, if necessary. Several of them gave estimates of Good, Better, and Best. The difference of Best costing not very much more, and includes a netter roof ridge vent and upgraded breathable shield layer. They all included releading the chimney, replacing the second story bathroom vent, and full 8 in edge stripping. The other minor difference was the length of the labor warranty. Ironically the most expensive quote had the shortest (5 yr) labor warranty. Most were 10 years. The latest generation of GAF HDZ shingles has a 50 yr warranty and a 130 mph wind rating. (compared with 20-25 yr with asphalt shingles 15-20 yrs ago.) By far Exteriors Unlimited came in at $11,100 with the same terms. In addition, the work was professional, Chad was great to work with, and our 2400 sq ft home was done in one day (7:30 AM to 4:30 PM). When done, clean-up was exceptional. I think our Eagle-Eye 12 yr old grandson found only 1 nail and no other rubbish. Very Highly Recommend!"

"I had to have the roof of my garage replaced and I got a very good estimate from these guys and I engaged them to do it. They were professional and had to do a fair amount of restoring of rotted wood and had to remove three layers of asphalt shingles off my old garage. Anyway, they did this for $3,310 for a 300 sq ft roof. That was a far lower estimate than the other places that I got estimates from. The quality of the work is wonderful and they did an excellent job of cleaning the interior of my garage because when you think about it, for most roof replacements, the dirt is up in your attic. My garage is a workshop with benches and shelves everywhere and they did a very good job of cleaning up afterwards. I give these guys an unqualified recommendation."

"They did a great job with my roofing project. Erik was great to work with, he was fast, honest, and friendly and Scott's install team was incredibly professional. My roof looks awesome. Would highly recommend and will work with them again for our windows."
