Meet the
Pack
Big Dog Roofs is a family-owned, Pennsylvania-tough crew that has been protecting homes in the Sewickley Valley and across Allegheny County for nearly two decades. We're not the cheapest. We're the ones who do it right.

From One Truck to a Whole Pack
Rex Calloway started Big Dog Roofs in 2008 out of the back of a beat-up Chevy with his bulldog Tank riding shotgun. The plan was simple: do roofs right, treat people fair, never cut corners.
Eighteen years and 2,400+ roofs later, we've grown into five full crews working out of Butler County, with the same rule book. Tank's gone — but his hard hat hangs in our shop, and his attitude lives in every job we touch.
We're licensed, insured, GAF-certified, and BBB A+ rated. But what we're really proud of is the wall of customer letters in our office. Read a few when you stop by.
What We Stand For
We say what we'll do, then we do it. No upsells, no fine print.
Once you're pack, you're pack. Lifetime priority callbacks for past clients.
We work in PA snow, sleet, and 90-degree summers. The pack doesn't quit.
