Good day Chris & Clay,

I will get the purchase order out to you today for the service work.  

I also just wanted to take a minute to thank you guys for the outstanding service that you continue to provide to our company. Your standards and integrity are aligned with our cultural beliefs and is what sets you guys apart from your competitors.

I’ve never had a bad experience in my 22 plus years of working with Interstate Roofing. People like yourselves, Dan, Tim and Butch are always courteous and professional. You have all been a pleasure to work with.

Thanks for everything you do for us, and I look forward to many more years of great continually service from Interstate Roofing.

I can't express enough how much we value Interstate Roofing and Waterproofing.

To date, and after completing more than six (6) MAJOR historic restoration projects ranging from 4,000 square feet to over 14,000.00 square feet, Interstate Roofing has always done the job perfectly. These types of projects are not your everyday, run-of-the-mill, new construction jobs ... you never know what you are going to find with these restorations, and we found a LOT wrong with every project. Interstate took care of every historical issue that we uncovered, and did it with a good attitude.

– Ken Riley
