Recovering a flat conventional roof with metal gives building owners an opportunity to enhance the aesthetics of their building, improve performance, and increase energy efficiency.
Flat Roofs
Flat conventional roofs are more commonly referred to as low slope roofing because most roofs have some slope to them. Roofs that are actually flat can have many problems, especially drainage related.
Flat, or low slope, roofing is most often found on buildings with large footprints because traditional roofing requires a higher slope that can be impractical and costly for the design. Schools, apartment buildings, warehouse, factories, and big box stores all tend to favor this style of roofing.
Flat Roof Recover Options
When the time comes to replace or recover a low slope roof, there are a number of options available. Which option is best will often be determined by the type of roofing that is already in place. Concerns about high wind and hail, longevity, and aesthetics can also play into the decision.
Built-up roofing, single-ply EPDM, modified Bitumen, PVC, and spray-applied coatings are all commonly used commercial and industrial roofing solutions. Spray-applied coatings tend to be the least expensive option but are also the least performing. Built-up roofing solutions are also falling out of favor with building owners preferring singly ply solutions.
Another option building owners have for industrial or commercial flat roof recover is a metal roof. There are a number of reasons that a building owner might select a metal roof recover over other alternatives. For instance, metal roofing offers excellent longevity with typical metal roofing lasting 50+ years.
Metal is also more resistant to puncture from hail which can be a significant concern if the interior of the building houses expensive components, parts, or is in frequent use (like in schools or apartments).
Metal roofing might also be the ideal replacement solution if the roof is structural by design, the roof is also the ceiling, and there is no deck.
Low Slope to Steep Slope Recover Metal Roofing
Low slope roofing is known to have a number of issues, and owners can get tired of fixing the problems of a flat roof that may have ponding water and leaks from internal drains and pipe penetrations. Sometimes the scuppers become clogged, and the water backs up, and that leads to issues as well. For some building owners, these issues become too much of a headache, and they want out of low slope roofing altogether.
Alow slope to steep slope metal roofing recoverenables better water drainage off your roof and can also add design features, increasing the aesthetics of the building. This type of recover also means that if you have a rooftop HVAC system, you can now protect the equipment from the elements. The addition of insulation during this type of recover also has the added benefit of increasing energy efficiency.
