5 Sneaky Flat Roof Drain Issues For Commercial Roofs
Commercial Flat Roofs (and Flat Roofs in general) are notorious for ponding. Most of the time it’s due to drainage issues. If you have a commercial flat roof drainage will cause your roof to NOT last 30-50 years. In fact with drainage issues and ponding most likely not even half of that. Whether your flat roof is in Orange County, Los Angeles, or anywhere else on planet Earth these are 5 Sneaky Flat Roof Dain Issues For Commercial Roofs that you need to be aware of!
Flat Roof Drain Issue #1 Location
Drains should not be located near or next to other rooftop objects like A/C units, vent pipes, or skylights. If the drain is located too close to other roof equipment such as A/C units, this could cause debris to get trapped and stuck which could clog up the roof drain. A clogged-up roof drain over time can cause significant damage to your commercial flat roof.
#2 Drain Level
One little-known fact is that flat roofs are not exactly flat they do have a slight slope AND for good reason. Drain almost always have to be installed in the lower section of the roof. A good commercial roofer will remove the existing plywood and lower the drain to include a square catchment area around the drain. This will help with the collecting of debris and keep the drain flowing.
Drain strainers with small mesh holes cause debris to get trapped and thus clog the drain. As for Dome strainers, they’re too high in profile and can cause debris build-up.
Often overlooked, but if your property is near trees that are less than a foot away from your roof, that is bad news for the drains. Tree branches and leaves clog up the drain more than anything. So if you’re building is near trees make sure regular maintenance is part of your plan.
Piping that leads from the drain CANNOT be too narrow. If it is the volume of water that needs to flow during rainstorms will not be able to, and cause major issues to your drain and roof.
The bottom line is flat roofs have different types of issues than slanted or sloped roofs. They’re going to need a bit of extra care. But with a great drainage system in place, your commercial roofing system will last a very long time! Just remember to check your roof once in a while and address minor issues before they become major ones. Doing so will save you money!
WHAT DO THEY SAY ABOUT CENTRAL ROOFING
I recently have had some repairs done to a commercial building we have here in California. I have tried other vendors in the past and usually get left with areas... read more that need future repairs. The few times I have had Central Roofing out for repairs and maintenace the roof always seems to be in better operating condtion then prior to the repairs made by them. I highly suggest Central Roofing for roof repairs at our various buildings.

I never write reviews but Central Roofing has impressed me so much by doing such an excellent job that I want to spread the word so that others are aware... read more of this talented roofing company and team. We have a large commercial roof over five tenant businesses. After years of dealing with numerous roofing companies who unsuccessfully attempted to repair ongoing roof leaks every time it rained, I finally contacted Central Roofing, Dave Wilkes their highly knowledgeable project manager, to fix our commercial roof. Central Roofing is the best roofing company I have ever dealt with. They really CARE, are highly responsive, trustworthy, conscientious, dependable, hard working and very customer and tenant focused. It continues to be a pleasure dealing with each and every member of their highly professional team. Central Roofing worked hand-in-hand with me to devise a commercial roofing solution within our budget to eliminate the recurring serious roof leaks. Central Roofing restored our commercial roof and, extended its life 15 years. Our roof restoration took approximately a week during which Central Roofing actively pre-coordinated all roofing repairs not only with me but also the building tenants to ensure no business interruption. Whenever I have a question or solicit their input, Central Roofing's entire team is always very responsive. Central Roofing has my business for life! -On behalf of Kim Holmes
