The most recent work they did was shingle repair around an attic fan that was leaking. They get an A grade from me, though I did have to wait a little while for a call.”
“I had a rubber covering over a carport that had started leaking and they came out and replaced it.

“My experience was positive because they did it in one day. They brought enough people because of the weather. There had been a hurricane, and they had been trying for weeks. They came with a group of people, completely took it off, and put a whole new roof on in one day. The cleanup was fantastic, and I would give them an A+.”
“I think they did a roof patch for me. The experience was positive because they were on time, they did a good job, and they cleaned up after themselves.

The cleanup was good. They did not leave any materials behind that we noticed. We had wind damage, so some of our shingles had come off. They replaced those shingles, and they searched the roof for other damage and fixed a couple of things. I would use the company again. They completed the work to our satisfaction—there were no issues. I guess they get an A.”

They were knowledgeable and courteous. They cleaned up after themselves when they were done. I think the estimator was really good. I would give them an A+.”
“We needed a roof for our sunroom. We originally wanted it shingled like the rest of the house, but they weren't able to do that because of what it was built with originally. So they came up with a great option for us, and they delivered. It was excellent quality of work. I would use them again. I would give them an A-.”
“Using An Exterior was an outstanding experience. They put the original roof on the house. After it was damaged, they put a new roof on—it was great. I never saw the workers, but they were good, and they cleaned up after themselves. They were honest, and they got the work done. I give them an A.”
“They did a pretty good job, and they were very professional. They put some flashing back on the roof, and then they fixed the roof. They cleaned up really well and finished the work in a reasonable amount of time. I'd give them an A+. They were pretty good.”

Based on what I was able to see and the pictures they showed me afterward, I would say they should get an A+.”

“I had a positive experience. They were on time. They were very courteous. They knew exactly what the problem was. They fixed it without any problems, and I didn't have to call them back.

When everything was totally done, the cleanup was like they had never been there. They were very courteous and accommodating. They also fixed the siding on the house. A+.”
“They were fine. I had a positive experience with them. I heard about them from Best Pick Reports. They fixed a roof leak that I had. I have not had any more problems with the leaking or anything.

“They were OK. I wasn't there when they did the work, but the renter—now homeowner—was there. I liked the fact that they fixed what they started out to fix.

“They did a great job for me, and I would use them again. I still have their number. I had to have some shingles replaced and work done on the gutters in some places where they were loose. They got my house to where it passed a home inspection. The guy from An Exterior was doing work on another home, and he fit me in. I didn't find nails or anything when they finished. I would give them an A.”
“It's been a good experience with An Exterior. I used them for shingle replacing. What made them good was their fast response. They cleaned up after themselves. I would rate them an A.”
“They did a fine job. They did the work that needed to be done. They gave a good diagnosis of the problem, and they performed the fix very well. It was about a year ago. We had a leak in our roof, and it was associated with the installation of a satellite dish. We noticed the leak was coming into the roof, and they inspected the satellite base that was installed on the roof and found that the satellite dish installer had not provided sufficient insulation or whatever protection was required to prevent it from leaking. An Exterior fixed the problem, took photos, and helped us initiate a claim with the satellite dish company. We haven't had a problem since, and we were very satisfied with the work they did. I'd give them an A.”
“From start to finish, I would say my experience with An Exterior was positive. This was my first time using them. They did my roofing, and everything has held up well.”
“They repaired a leaky roof on my side porch late last year, and everything was great. They gave me an estimate via email and did the work the following week. It looked great, and everything was all cleaned up. They did it in a timely manner. I give them an A. I would use them again.”
“An Exterior is very good, and they work as a team. I used them for roof replacement. They are very good at doing estimates, and they finish the job on time. I would recommend them. I give them an A.”

“An Exterior replaced parts of our roof, and the quality of the work was good. I have no idea if they used a magnet afterward, but the cleanup seemed good. They were recommended to me by someone, and I would use them again. I would give them an A.”
“I'd give An Exterior an A. They installed a skylight in a timely manner, the customer service was fine, and it was kind of hard to tell, but I'm assuming they cleaned up well. I would probably use them again.”

I love the roof—I thought they did a great job. They were very prompt with scheduling. I would definitely recommend them, and I would definitely give them an A+. I was very satisfied with An Exterior.

An Exterior did an excellent job. They replaced the shingles and a whole lot of plywood underneath. They came when they said they were going to come, and they were just so professional—it was kind of refreshing. They just made me happy. A+.

I used An Exterior for roofing, and they were very, very good. The owner of the company came out personally. The quality was excellent, and the cleanup was very good. They're A+.

An Exterior did a very nice job. We have used them a couple of times. They replaced the roof, and they replaced a skylight. They cleaned up well after their services.

An Exterior came out to do some work. They replaced the entire roof. Everything went great. Dealing with the folks in the office was a pleasure. The crew that came out was great. They got the job done a little bit ahead of schedule. They did a very quality job. The guys were very nice, and they cleaned up afterward. They were very friendly and professional. No complaints at all; the roof is holding up great. This was all precipitated by the earthquake that came through the east coast. My house is 25 years old, and I've never had a leak. A month later after the earthquake, we had all that rain, and I had three leaks. Now, there are no more leaks anywhere. If I needed them in the future, I would absolutely call on An Exterior again. In fact, I'm considering using them for an addition that we might want to do over the summer.

They were great. They replaced the collars on two or three pipes, and they put some caulking or silicone on them. I haven't had any more leaks. They did it right away, and they were willing to do it right that day.

An Exterior did roof repairs within the last four years. It was not an extensive job, and it didn't take them a long time. It was a quick repair. I would use them again in the future for roof repair.

They had to replace some shingles. I was pleased. They cleaned up after themselves, and they got the job done in the amount of time they said they would.

They replaced some flashing around the skylight and an exterior pipe coming out of the roof. It was fine. The cleanup was extremely good.

They replaced my roof. The work they did was great. They only replaced whatever plywood wasn't good. They were very honest, because that was the only variable cost in my estimate.

I had roofing repairs done by An Exterior. The service was good. I'd give them a call again. Everything was fine.

That guy was excellent. Originally he looked at it and said everything was OK. Then we went inside, and I showed him the water stains, and he did a repair on the pipe. I was very happy with the work.

They did a roof for me, and they did a great job. They did what they said they were going to do and then went on their way. Their cleanup was good, and I would use them again if I needed to.

They cleaned out the gutter and retacked it to the ridge. They also fixed a hole in the roof. I don't know how they could possibly do that, but they did. I was satisfied; I haven't had any problems. It's the kind of work where it's difficult to tell whether it was done well or mediocre. They did the work a month or two ago, so it's not long enough to know whether or not the leak is OK, but we used to have a little bit of a leak down into a bedroom, and we haven't had to experience that anymore. I would rate them a plain A.

We had a roof leak. We ended up using An Exterior. We were happy with the work they did. They did the work before Thanksgiving, probably in October. They got the work done quickly, and they cleaned up after themselves. It was a good effort; I would use An Exterior again.

They replaced a section of roofing that was burnt. They were prompt. They did the work right, and they stuck to the estimate. I think this was the second time we used them. I would give them an A+.

They responded quickly and did a great job. They fixed the roof over six months ago. They were recommended by a friend. I would give them an A.

They just replaced my roof. My experience was positive because they did a good job. I would I hire them again. They deserve an A.

They did a good job. Everything was on time. When they said they were going to be here, they were here, and it only took them a day. It was a pretty smooth experience, especially compared to other contractors. I have no complaints; I was quite happy. They replaced the roof, and it was my first time using them. I was referred from a friend. They met my expectations, and everything turned out well. I'd definitely say they get an A+.

They came on time, and they did what they said they would do. They fixed a leak in the roof. The project took a month and a day. The customer service experience was fine—no problems. This was my first time using the company. I would grade An Exterior an A+.

They did some roof repairs for me, and they did an excellent job. I'd give them an excellent referral. They came out when they said they were going to be here. Their foreman was very friendly. They did a thorough investigation of what the problem was, and they gave me an estimate quickly. The roof is not leaking anymore. We've used them previously. It took them about four or five hours to do the work. I'd give them an A.

They did roofing work. They were reasonable, quick, and efficient. They did fine. This was the second time I've used An Exterior. Sometimes, it seems like I have a run of bad luck with some people who do work. An Exterior meets the standards of professionalism that I expect. They're quick and efficient, and they answer phone calls; the fact that they do that is very encouraging. I would definitely give them an A.

They did roofing repairs. They seemed to be honest and reasonable. I heard about An Exterior through a friend. The project was very small and only took a couple of hours to complete. I'd give them an A.

They did our whole roof, and they did a repair job last year. They put a new roof on for us several years ago, and they've come back several times to do some repair work for us. It's very easy to get them to come out and do a repair. They're usually professional and polite when they come out. Sometimes, the general comes himself.

Everything went well. We've never had any issues. We used them for a roof repair. It was a minor job, and we didn't have any issues with them.

We used An Exterior . There was a small leak in our townhouse. The builder didn't seal the flashing correctly. They come out and sealed the flashing, and they removed a satellite dish and patched the holes.

It was very good. They had to patch and seal a couple things.

An Exterior did an excellent job. I went up there and looked at the roof myself. I’m a general contractor, and I used to do a lot of residential, so I knew exactly what I needed to have done and how I needed to have it done. They get an A+.

An Exterior was superb. They were really good. They did excellent work. They explained everything they were doing, and we were very pleased. The work is great—perfect. I would rate An Exterior an A++++++.

An Exterior did the roof, and they did a fantastic job. They came quickly, it was done right, and they finished up in a timely fashion. They were wonderful.

They were extremely good. They put on a whole new roof. I would absolutely recommend An Exterior.

The company is excellent, absolutely excellent. They put in a roofing system and skylights. They’re wonderful. They did quite a big job. They finished that job in an appropriate amount of time. I couldn’t believe how fast they were. I would use them again.
