RV type
Camper vans have small roofs with a lot going on: a fan, solar panels, maybe a pop-top or a fiberglass high-top grafted onto a steel van body.
The joint between the factory van roof and an aftermarket high-top is where most Class B leaks start, because two materials with different expansion rates are bonded together.
We'll get on the roof, photograph what we find, and give you a fixed written price. No charge and no pressure.
