Flat Roofs
The roof on your business is its first line of defense against the elements. It offers protection from rain, wind, snow, and sun. Yet over time, even the strongest roof will eventually show signs of wear and tear. Here, you'll discover four types of common flat roofs plus how to know when it's time to replace your existing flat roof.
Four Common Flat Roof Materials
When installing a new flat roof, there are four common materials to choose from.
TPO Membrane: TPO membrane, short for thermoplastic polyolefin, is a single-ply white membrane that can be used in commercial and residential spaces. The white membrane reflects heat, making it great for spaces where cooler temperatures are preferred.
When properly installed and taken care of, a TPO flat roof typically lasts 25 years.
PVC Membrane: The PVC membrane, also known as polyvinyl chloride, is also a single-ply white membrane roof. Like the TPO roof, the PVC roof is great for both commercial and residential spaces. However, the PVC roof has been around longer and has proven to be slightly more flexible than the TPO membrane.
Again, when properly installed and taken care of, a PVC flat roof will last for approximately 25 years.
EPDM Membrane Roofing: Short for ethylene propylene diene terpolymer roofing, the EPDM roof is more durable than both the TPO and PVC roofs and is a black synthetic rubber membrane. The result? Thanks to its black color, it is quick to absorb heat. EPDM roofing is a common commercial solution.
When properly taken care of, EPDM roofing will typically last 25-30 years.
Standing Seam Metal Flat Roof: If you're looking for longevity and some handsome curb appeal, say hello to the standing seam metal flat roof. It is made from a series of metal panels that are either locked together at the seams or seamed together mechanically.
This roof comes in a variety of colors meaning you can coordinate it with your company’s exterior appearance. Not to mention, when well taken care of, a metal roof will typically last at least 30 years and in ideal conditions, can last as long as 50 years!
Thanks to it's more durable character, expect a higher budget for the standing seam metal flat roof.
Five Ways to Identify When It’s Time to Replace a Flat Roof
How old is your roof? The first thing to consider is the age of your roof. If you are nearing the 20-30 year mark (depending on your roof material respectively), it's likely you'll need a replacement soon.
Flat roof leaks How often are you checking your roof for leaks? Unchecked leaks can lead to severe water damage over time. Signs to watch for inside your building of an undetected leak include discoloration, mold, or mildew on your ceiling.
Pooling water Most flat roofs typically have a 15-degree slope to allow water to runoff. However, it's not uncommon for older roofs to warp ever so slightly, thus creating water buildup on the roof. And as you can imagine, these puddles of water can soon lead to more extensive water damage.
Disintegrating flat roof panels Check the sealant on seams, around roof panels, and on your pipe collar. If the sealant is cracking, dry-rotting, or deteriorating, it's time to replace the roof.
Damaged flashing on flat roofs Inspect the metal flashing around your chimney, vents, and other fixtures. Look for any signs of lifted, damaged, or missing flashing as this can result in severe moisture damage if left undetected.
