Avoiding Commercial Roofing Condensation Problems

By October 28, 2018 No Comments

Seeing those little water droplets that start to form as a result of condensation issues on your commercial roofing in Seattle can make any building manager sweat, but with the right maintenance and planning you can rest assured that your building is not going to suffer unnecessary damage from condensation.

Know the Causes of Condensation

Any time you have warm, moist air inside a building and cooler air outside, you can run into condensation problems near your roof area. Winter is a particularly problematic time of year for many building owners in the Seattle area because it’s a time when there are cooler temperatures so furnaces are running, and there is a lot of precipitation, creating humid conditions.

Other signs that you might have water in the area are:

Drips coming from the ceiling where there is no discernable leak (particularly during the middle of the day when temperatures are warmer)
Crunching or crackling noise when walking on the roof in colder temperatures (when the water has frozen into ice)
Warped or damaged insulation beneath your roofing membrane
Water and condensation issues can also be exacerbated by cool roofing, which reflects the rays of the sun and keeps roofing colder. When that cold roofing comes into contact with warm air from inside, the condensation is created.

Ventilation Issues

Another common reason buildings will develop condensation problems is the lack of appropriate ventilation. This is particularly noticeable for buildings that have metal roofing, and have a high level of relatively humidity (over 50%) inside. If your building has a high occupancy rate, such as a gymnasium or a warehouse full of employees, it can also increase humidity and temperatures inside. These problems can often be addressed by having a Seattle commercial roofing contractor add proper ventilation, increase insulation, or make some changes to the vapor retarder on the roof.

Allowing condensation problems to continue will often lead to other issues, including mold and mildew growth, damaged insulation, and eventually total roof failure. Keep accurate logs of the condensation issues and efforts to remediate them so you can address the problem appropriately.
