Low rib panels can generally be ordered in two different thicknesses of either 29 gauge or 26 gauge. Low rib panels are commonly used on residential property while the later two types are designed for commercial applications. Metal roof panels come in different types, i.e., low rib metal panels, PBR panels and Snap-Lock panels. Since my daughter and son-in-law’s house is located in the Sunshine state with little to no shade around it we decided to install 3/4″ iso-board insulation over the existing roof before the installation of the new metal roof for an added layer of protection. Another benefit of a metal roof is that it can be installed over an existing asphalt shingle roof or modified bitumen roof by simply putting down a layer of roofing felt or insulation board between the original roof and the new metal panels. The primary maintenance issue is having to replace the screws every fifteen to twenty years because the washers will deteriorate over time. The biggest is that they will last virtually forever. The old modified bitumen roof is shown prior to replacement I suggested that they consider installing a low-rib metal roof since I had installed several of these before for a fraction of the cost of their professional estimates. They obtained two different quotes to replace their roof with modified bitumen, or a comparable product, but those quotes were enough to buy a brand new economy car. The roof on their house has a very low slope, a 1:12 pitch to be exact, and came with an 18 year old modified bitumen roof that was at the end of its life expectancy. My daughter and her husband recently bought a fixer-upper in Florida. Alternative Heating & Fireplace InsertsĪ New Metal Roof Tops Off a Florida Remodeling Project.
