Although ROOFTOP® may have a higher initial cost compared to other materials, such as metal roofing, over the long term, it offers a much better return on investment. In addition to not requiring extra insulation, ROOFTOP® is virtually maintenance-free, so there are no additional costs after the initial installation. ROOFTOP® is also rust-proof, weather-resistant, and has a lifespan of at least 20 years (with a proven 20-year warranty), meaning you won’t need to replace your roof every 3-5 years like other types of roofing.
