We Got You Covered

Learn About Us:


When you invest in renovations for your home, you naturally want to enjoy the additional peace of mind that comes with a product warranty. Tristate Roofing understands the need for a lasting, durable warranty that customers can count on in the event that their roof, windows, gutters, or doors are damaged. As a result, we only use brands that offer robust product warranties to help protect you in the event of a system failure—or even just a simple defect.


Depending on the products that you select, you'll likely receive a guarantee that ranges from a few years up to a limited lifetime warranty. Our contractors will go over the documentation with you, so you’ll understand completely what is covered and the length of the exact warranty period. As GAF Master Elite Roofing Contractors and IKO ShieldPRO plus+ Contractors, we're part of an exclusive group of roofers in Washington. In addition, we have earned the distinction of being a Pella Platinum contractor which is only achieved by 1% of contractors in the nation. And, we are a James Hardie Preferred Contractor. Our team has been extensively trained before being certified by these brands as able to provide superior installation services. Our expert status also gives us the opportunity to offer additional warranty perks to customers. When you invest your trust in us, we'll make sure that you receive a superior written guarantee that you can rely on.

Let me tell you. Working with Sean D was a pleasure. He came out inspected our roof and then we talked options. He was super helpful in explaining first the roof we had. It was very old, sagging and beginning to leak. On top of that we not only had one old layer but an even older layer under that. Then we talked the options available on getting us right. Now I can look forward to not worrying about my house in bad weather. I highly recommend.

Sean Stimmel inspected our roof and attic then gave us a thorough report on the condition of our roof. He presented detailed information and presented options for next steps for us, including what would provide the best value for us. He was thorough, respectful, and responsive to our needs. We appreciated his input and are happy with the choice we made. Thank you Sean.

The salesman Jason Phelps from TriState Roofing, did a fantastic job explaining the product and process to my wife and I. As an inspector myself I deal with a lot contractors. Some good and some... well you know. Jason was very honest and easy to deal with. I know Tristate has been around for many years with a great reputation. Looking forward to a brand new roof. Thank you for welcoming us to the family. Dale and Karen Blackwood
