Solutions for R-panel metal retrofits

Metal roofs are often sold as the last roof a building owner will ever need. But most roofing professionals have seen the effects weather can have on a metal roof over time. Corrosion, open joints and seams, leaks at penetrations, and other issues plague metal buildings when exposed to harsh weather conditions. In Texas we often have days where the temperature can fluctuate up to thirty degrees Fahrenheit. These temperature fluctuations cause metal to expand and contract at a rapid rate, opening seams that rely on an underlayment to remain watertight (or sometimes nothing at all).  What solutions are available for metal building owners?

Most common solutions are coating, metal replacement, or single ply recover. All three options can be viable depending on the scenario yet also have their own challenges. Coatings require maintenance and often include many exclusions in the warranty. Metal replacement is costly and qualified contractors can be hard to find. Single Ply recovers have long been one of the best most cost effective solutions. However, when the metal building contains skylights or internal gutters the cost of a single ply recover escalates.

Recently, a new cost effective solution was presented by Exceptional Metals through partner MBCI for roofs with existing under deck insulation. The PBR metal retrofit panel easily fits on top of existing r-panel roofs utilizing a fleece back to separate old panel from new. These can be cut around existing skylights with ease. The cost is less than a single ply recover although roofs without proper insulation underneath miss out on the benefit of adding flute filler insulation and a cover board to their existing metal roof.
