D M Norris Co Inc

There was a slight delay due to the rainy spring/early summer, but once they were able to start everything went perfectly smooth.  They were a breeze to deal with.  All the guys working here were polite and friendly.  They did EXCELLENT, high quality work.  The roof looks amazing and it was not an easy job to do.  This was a replacement of the original standing seam roof which was over 130 years old! 
They kept a clean workspace and promptly cleaned up everything once the job was done.  They showed up everyday until the roof was complete.
I've hired a lot of sub-contractors for various jobs on our historic house downtown and these guys were one of the easiest ones to work with.  When it comes to historic roofs and box gutters, they really know what they're doing!

Recently, a contractor we chose to replace our copper gutters found several issues that were wrong with their installation.
Minuses:
1. Bird guards under the tile openings were nailed in their place. They should have been attached a few tiles up and hung with wire so that water can run under the bird guards if it were to penetrate and so that the nail doesn't interfere with the expansion and contraction of the copper gutters. It is likely that some of the nails loosened over time, and because they are at the edge of the roof, allowed some rain to penetrate and rot the wood and make it damp enough to provide an ideal environment for the carpenter ants we found present.
2. They were supposed to replace rotted wood on a time and materials basis. However, it was found that they neglected to do so where they should have replaced the wood. Places include at the edge of the dormers and also on the pitch of the roof where there are significant gaps between boards. Now, in order to repair damaged 100yr old bead board and trim along the lip of our dormer, we will have to pay 1,000s of $ to a roofer to remove the tile along the dormer so that we can replace what should of been replaced when the tile was already off.
3. An extremely thin wall of flexim was installed along the hip and in other areas. Flexim is expensive and instead of filling the entire cavity, paper was stuffed in it to fill up the majority of the void and less than a 1/2 inch wall of flexim was applied. This cracked and deteriorated over time due to its lack of thickness and eventually broke away from the tile. Had it been a thicker application, then water might not have penetrated. Plus, they chose black instead of a matching green color.
4. During 2012, they did some work to tuck point a chimney and left a lot of splatter all over the brick. I brought this to their attention, but they never came  back to scrape it off.
Pluses:
1. They did a great job removing and replacing the tile. The avoided damaging very few and put them back on in a uniform way.
2. They operate in a safe manner and got the job done quickly.

They were very professional and delightful to work with. They were on time and did their work. We were in the emergency situation and they were just fantastic.

They told us when they were going to come out and did a great job on the skylight. We started having some water in the roof one more time; they came out within a couple of hours to diagnose the problem and repair it. I would never hesitate to use them again in the future.

The workmen came exactly when they said they would and were extremely thorough in their workmanship. When it rained a few days later we had more water problems in the dining room. They responded immediately and diagnosed the remaining issues and the problem was fixed.

They did a very good job. They kept coming out until they had it fixed. We have had other roofers out who were unable to fix it. They finally fixed it on the third time.

Dave Norris showed up promptly to give his estimate, then came to do the job as described - on time and on schedule.

This was really a big job. We live in a big city house. The old tiles were aspestus and a special company came to remove them. Then the roofers did the whole house in 2 1/2 days. The gutters are the kind that we do not have to clean. They did a great.

The 165-year-old slate and metal-roof house that we were considering purchasing had multiple water issues. We initially called Dave Norris to evaluate the roof prior to purchase specifically based on his experience with historic homes. The house is large and the roof extensive, with many different rooflines. Dave spent most of the day inspecting the roof, taking measurements and drawing a detailed plan of the rooftop and gutter systems. He identified the sources of active and past leaks and put together a plan of action and estimate of costs, prioritizing which sections were in most urgent need of work. All of this he did before we even purchased the house, at no charge to us. (Once we bought it, we called another, well-known slate roof company, who spent less than an hour looking at the roof and then gave us an estimate for more than $250,000. It was obvious he was not serious about the job.) DM Norris got the job and the team worked on our home throughout the winter, often in single-digit weather. When the weather was warm enough, they worked on the rubber roofing, and spent colder days reconstructing the gutter system. I have never seen a harder-working crew. Everyone was courteous, friendly, polite and very skilled at their craft. We have two more sections of roof to work on in a few years, and I will not hesitate to call Dave Norris again when we are ready to begin that project.

The workers are very professional. The price was very competitive with other companies. It looks great and everything is draining fine. We are very happy. They were very easy to work with.

I WAS VERY IMPRESSED WITH THE OWNER, DAVE NORRIS. HE WAS VERY HONEST (COULD HAVE TOLD US TO USE COPPER) AND DEPENDABLE. HE SHOWED UP TO DO THE ESTIMATES AS PROMISED WHEN OTHER COMPANIES WERE EITHER LATE OR DIDN`T SHOW UP. ALSO HIS PRICES WERE VERY COMPETITIVE. HIS SECRETARY GOT TO KNOW US PERSONALLY AND DAVE DIDN`T HAVE TROUBLE SHOOTING OUT REFERENCES FROM WORK HE PERFORMED IN OUR NEIGHBORHOOD. THE ONLY COMPLAINT WAS THAT THE WORKERS, WHO WERE RATHER YOUNG, LEFT LADDERS OVERNIGHT IN OUR NEIGHBORS DRIVEWAY. OVERALL THEY WERE FRIENDLY AND EVEN TOOK BEFORE AND AFTER PICTURES FOR US.
