It was recently brought to our attention by one of our residents that the metal roof vents on our homes have been developing holes at the base where the metal vent is fastened to the roof. These holes are causing rainwater to leak into the wood and then leaking into the inside ceiling of the home.
The main cause of this corrosion of the metal vents is the chlorine that some roof cleaners are using to kill the mold and mildew on the roofs. Because the roof vents may not have been properly sealed with the right materials to prevent this type of corrosion caused by the chlorine solution. If you haven’t, please make your roof cleaner aware of this issue. The best practice is for them to cover the vents with some type of plastic covering while cleaning the roof.
We recommend you have your roof inspected for this problem, either by the cleaner, or by a roofing specialist.
