Gannon's carries lines of skylights from Velux and Sun-Tek. These are not the old plastic-bubble skylights, requiring gallons of messy roofing cement to shed water while becoming cloudy and brittle over time. Instead, these true glass skylights, available with insulated glass, venting windows, and accessories like sun shades and electricly-operated remotes. Whether you need standard sizes or custom-built skylights, Gannon's can help. Due to the vast selection of sizes and accessories available, all skylights are special order, normally available for delivery within a week.
