In order to construct his under-deck roof, Rune went to a home center and purchased corrugated fiberglass panels. *Rune Eriksen is a retired electrician who has spent the past 20 years creating his ideal lakefront cottage, garage and shop.Purlins made of pressure-treated 2×4 lumber should be fastened to spacer blocks of the appropriate size to provide a slope from front to rear.After that, attach the panels to the purlins using screws. The panels should be trimmed to the appropriate length.The majority of panels may be as long as 9.8 meters (32 feet).If you anticipate needing to finish the run in many laps, give yourself a minimum of 18 inches (46 cm) between each circuit. How do you top a corrugated roof?Ī garden shed, a business, or even a patio may all benefit from having corrugated roofing installed.You can do it yourself, it won’t cost you much money, and it will be done quickly and easily.You only need a few fundamental tools and components for this. Applying caulk or sealant between the two overlapping sheets will result in a roof that is more secure. Put a second sheet of corrugated material next to the first one, but this time make sure the ridges of the two panels overlap. As you go closer to the sides of the roof deck, you may need to trim panels to make them fit.
