What to do if your flat roof is leaking
Call us right away. The longer it sits the bigger the problem. If your roof is relatively new, repairing any leaks or damages should be your first go-to solution. An average flat roof repair can cost anywhere from $200-600.00, which is significantly cheaper than the cost of full replacement. Moreover, having a pro repair your flat roof can easily extend its service life by at least 3-5 years. However, in some cases, trying to fix a leaking roof membrane might be a futile effort and a complete waste of money. Often leaks, water damage and other issues may be the result of faulty installation, poor maintenance, or old age of the roof itself. Here are just a few common flat roof problems and signs that warrant repair vs replacement, so you can figure out the most cost-effective and lasting solution for your roof.
Common flat roofing problems
Flat roofs have inherent design and installation peculiarities that often lead to performance issues and a shorter life span. Here are the top three:
A leak is the most frequent and common issue on any type of a flat roof. It usually happens as a result of ponding water that puddles for more than 48 hours, after the most recent rain.
Typically, water penetrates at the seams or flashings. It may also come from drains, chimneys, skylights, parapets and other penetrations. It is very rare to have a leak due to a puncture.
If water gets under the membrane, into the sheathing, mold and rot can occur. This is especially likely in areas with high moisture and frequent rain storms.
One of the most common issues for EPDM membranes is shrinkage. When rubber shrinks, it can pull off parapet walls, drip edge or a chimney.
This is more likely to occur on a large building, and on one where the membrane has not been properly attached.
Damage due to foot traffic
Another problem, especially for flat roof decks and commercial properties is heavy foot traffic. Maintenance personnel (mainly HVAC contractors) and other random visitors going out on the roof, dropping tools, walking over fasteners, etc. All these actions can accidentally puncture the membrane and causing other damages that need to be repaired.
