Roofing : Maintain Your Roof Drain
The drain is one of the most important parts of the roof to verify and maintain. In fact, a clogged drain or waste pipe can cause major infiltration and even damage to the structure, the decking, a gypsum or plaster ceiling and many other problems.
You can see that there is not much room left for the water to evacuate.
Regardless of the age of your (roofing) membrane, whether it’s 1, 5, 10, 15 years or more, the risk of infiltration or other damage is very high if your drain or waste pipe is clogged.
Water evacuation is essential.
Correction and Maintenance
You must check to see whether the drain opening has been obstructed by leaves or other items twice per year. It is also necessary to have your waste pipe cleaned by a specialized company after repairs to your membrane every 6 or 7 years.
Unfortunately, most owners only discover the existence of companies that unclog drains after there is a problem. Few do it as a preventive measure. Having frequently seen damage caused by a clogged drain (several times per year), we can assure you that, at this point, prevention is the best cure.
