Typically, this time of year through February is the part of the year that we don’t deal with excessive humidity for weeks on end. However, that doesn’t mean we shouldn’t understand how humidity may impact your roof. In fact, roof damage from the effects of humidity are wide spread and the reason for many calls to our roof repair team throughout the year. Not all damage from humidity comes from the humid air outside. Here are some things you should know about how humidity can impact your roof and what you should keep your eyes out for.
Your Home’s Moisture
When we run our air conditioner, part of what it does is removes the humidity from the air. This is a good thing because the less moisture in your home, the less chance of mold and mildew growth. However, in the late fall, winter and early spring where we run our AC much less, we end up with a more humid home. This can impact your roof. The moisture from showers, doing dishes and running the dishwasher and dryer rises. Ideally proper insulation in your attic blocks much of it from rising up into your attic. What does escape into your attic should be able to escape to the outdoors through proper roof ventilation.
Moisture that can’t escape from your attic can lead to mold and mildew growth on the insulation and roof deck. In extreme cases of homes with improper ventilation and exhaust vents that open into the attic we’ve seen wood rot. In these cases, the need for roof repair turns into a need for a roof replacement because the decking and roof structure are damaged.
When we start having days and weeks on end of high humidity, your roof doesn’t have the chance to dry out, especially when it’s in the shade. That often leads to unsightly roof streaking and staining which is often a type of algae. In roofing with organic materials, that algae is actually eating away at your roofing material. This can weaken the roof, leading to blown off shingles and a roof leak. Trimming back trees is one way to help prevent the growth. Regular roofing inspections can help reduce roof repair costs.
