What homeowners say
On a real client's site, these come straight from their Google reviews.
We got three quotes for a new flat roof. Gablestone wasn't the cheapest, but they were the only ones who went up on the roof, took photos, and explained what was actually wrong. Two days, spotless yard, and the final bill matched the quote exactly.
Found a leak two other roofers missed. Fixed in an afternoon, with before and after photos.
Storm on a Saturday, tarp on by evening.
