Called for a quote to present to our realtor. They said to email photos which I did. Called back a few days later asking them if they got the email because I hadn't heard anything. And was told flat out they aren't going to look at that or do that. Poor customer service. They could of called and told me that instead of me waiting around in hopes I was getting a quote.

Went with the company before and had no issues, however this time Diamond decided to rush through the job. I have an old house build in 1895 and I needed to replace the existing roof and installing new gutters. The initial assessment was done without actually going up on the roof. Later on during the job we were told that they had to remove some cedar shingles to add flashing.

They went and cut not only multiple rows of shingles out of my house but also removed 1-2 feet of the original cedar gables telling us they were rotten (which they weren't after inspecting the pieces that were cut out) After the claimed their job was done the town inspector looked at their work and wrote up a comprehensive list of problems with their installation and therefore did not approve the job.

With this information we confronted Diamond Roofing who tried to bullying us into paying the full amount. We refused to pay for an incomplete job and the damage and requested them to either inform their insurance company or fix the issues stated in the town inspector's report. It took them 1 1/2 months to finally complete the roof job and the repairs after the initial town inspection.

During the repair work I received multiple calls from Diamond's Management telling me I should pay the contract amount due to the repair cost being high and that they would need to pay their guys. I refused on basis of our contract which stated payment upon job completion. After a final inspection of the roof job by the town inspector, we paid the in the contract agreed sum.

As for the rain gutters, we were put on hold for multiple weeks with every possible excuse as to why they couldn't do perform the work. We were called today (11/28/2018) by the company's owner (Bill Martin) and were told that they refuse to conduct any further work. Even though we were scheduled for an install of the rain gutters for 11/29/2018. So with that I have old gutters, half of them hanging of the side of my house, letting rain water hit my siding.

If ensuring that you receive the work that you pay for by also ensuring that the contractor doesn't cause more damage to your house is called rude, then you know what type of contractor you are dealing with. I can not recommend Diamond Roofing

I was buying a property in the area and Tommy came out and inspected the roof for me free of charge He confirmed what I suspected all along, roofing that was not done by a pro. Tommy identified numerous trouble spots of concern. Because of this, he saved me 10k on a possible new roof. It was a real pleasure to work with someone as professional and friendly as Tommy. I will definitely use Diamond Roofing for all my roofing needs in the future and recommend them to my friends and family.

They did an excellent job on our roof! Fast, professional, and efficient - the cleanup was immaculate. We'd definitely recommend them! Thanks Diamond!
