When you call on Tri-County, we are happy to bring our years of experience to the table in solving your problem or completing your project.  Whether you need help with garage doors, pole buildings, metal roofing & siding, or auxiliary home heating, we don’t sell you a product, we work with you to find the right solution, at the right price, and deliver that solution in a timely manner.

It’s all about home-town service.  We’re your Southwestern PA neighbors, not some fly-by-night company or out-of-town franchise, and we bring the best in the USA and North American products to Westmoreland, Fayette, Somerset, Southern Allegheny, Eastern Washington, and Eastern Greene Counties.
