From quality products to quality people, it is easy to see why so many neighbors already chose Interstate Roofing. While comparison shopping, I found some competitors could take days to a week to respond, but Interstate was always prompt. Communication throughout the install was great. They had installers available, so our 2-story was completed in one day. The unpredictable weather had us worried as we’ve seen some companies take over a week.

We had an excellent experience with Interstate roofing. Oscar and Franco did the 2 day job. Oscar was informative and professional, taking pictures of the before and after. They blew off leaves and washed some of the siding for us. Oscar let me know every step and how long it would be and they cleaned up nicely when they were done. They sent out their inspector after the job was completed to make sure everything was done correctly. Very thorough.

The crew at Interstate were friendly and hard working. I felt like the sales person was honest and experienced and I was confident in my decision to hire them. The daily crew worked hard and cleaned up after each day. They came back at the end to clean up debris at my neighbor's house as well. I appreciated the communication and think the roof looks amazing. I would have appreciated a more comprehensive materials list because there was some confusion at the end of the job about whether or not the left over materials belonged to me or not, but I didn't have that information so I can't be certain. All in all I think they did a great job and would be happy to recommend them to others.

I am beyond thrilled with the job Interstate Roofing did for us. We have used other roofing companies in the past, however Interstate surpassed all of them from our interactions from start to finish. Their estimate was well detailed, the workers were here on time each day and communicated with me about their progress, they kept me informed on what needed repair versus just clean. The best part is I left on day one, looking outside and seeing all the debris all over our yard and I was concerned, however upon returning home they did such an amazing cleanup job it was like they weren’t ever here. On the second day not only did they clean up they also power rinsed the entire house, it all looked amazing. If you want the job done right use Interstate Roofing!!!

Of the 8 quotes we got for a new roof, Interstates was both the most competitive and professional. Ronnie and co did a great job from bidding to start date, and the crew worked long days to get the job done fast. All in a great experience.

We had a leak in the low-slope roof over the third story of our house. Interstate replaced old plywood and agreed to change the job description to eliminate instead of replace the skylight. We are very pleased with the crews, led by Roman ...
