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.
If the idea of roof replacement hasn’t crossed your mind before, you’re probably not alone. Many homeowners don’t think too much about their roof on a daily basis, and only realize that they need to do something when there is a problem. Waiting until you have a problem can lead to other issues, though, so it’s better to be aware of what’s going on up there on your Redmond roofing.

The Signs That it’s Time for Roof Replacement

Here are some ways you can tell that the need for roof replacement in Redmond is coming soon: Significant roof leaks – most roofs will spring a leak every now and then, and when it’s just a small leak or a small area you can usually fix it. If your roof has several leaking areas, or significant sections where water is coming through, it’s time to think about replacing it. Sagging roof deck – the roof deck is the support structure that holds up your shingles, and if it’s starting to sag in some areas, that’s a sign that there is an underlying problem that cannot be fixed with a cosmetic repair above. Talk to a Redmond roofing contractor about this right away. Mold and mildew in the attic – you might be able to spot the signs of a problem from the top of the roof, but by looking at the underneath area (in your attic) you can often see what’s not visible from above. Large areas of mold or mildew growth are a sign of leaks and water damage and may require roof replacement. Curling, cracking, or buckling shingles – if you notice that a significant portion of your roofing is showing signs of wear, such as curling at the edges of the shingles, cracks, or places where the granules are missing from the shingle entirely, that’s usually a sign of a more widespread issue that must be addressed with a replacement roof. Algae growth – as with the interior of your roof, a small section or mold or algae growth on the roof exterior might be something you (or a professional roofing contractor in Redmond) can clean up, but if it has spread over most of the roof, or if the algae has been growing long enough that it has eaten away the granules on your shingles, you may need a new roof.
