RoofSmart handles attic mold for homeowners in Auburn, WA, as part of the roof and attic work we already do. Attic mold is worth taking seriously because of what it says about moisture in your attic.
Washington's damp seasons give attics plenty of chances to collect moisture. In Greater Seattle attics, condensation is often the cause: warm, moist house air leaks up through gaps in the ceiling and turns to water on the cold roof deck. Left alone, that moisture can soften and rot the roof sheathing.
Here's why attic mold is worth addressing, and why the fix has to include the moisture source.
Mold grows where wood stays damp long enough, and an attic with poor airflow is a common place for that to happen. For health questions about mold, talk to your doctor or read the Washington State Department of Health's mold guidance.
The bigger risk to the house is the moisture behind the mold. Sheathing that stays wet long enough can soften and rot, and soft or delaminated sections have to be replaced.
Catching the moisture problem early usually keeps the repair smaller.
Some homeowners clean small spots themselves. Before you try, weigh these points.
We don't publish do-it-yourself cleaning mixes. Cleaning a wet attic buys time. It doesn't stop the moisture that caused the growth.
Attics are tight, with roofing nails coming through the deck and ceiling drywall between the joists that won't hold your weight. What you can see from the hatch is often not all of it.
Growth between rafters, around nail tips, and near the eaves is hard to reach from the attic floor.
Attic mold needs moisture, and cleaning doesn't tell you where it's coming from. Without fixing the cause, such as house air leaking into the attic, an exhaust fan venting into it, or a roof leak, the growth tends to return.
If you're unsure, start with an inspection that finds the cause.
We inspect the attic and the roof together, remove or treat the growth, and fix the moisture source as one job.
Our process begins with thoroughly inspecting your attic, identifying the extent of the mold growth, and finding any underlying moisture issues. We then develop a customized remediation plan based on your unique needs.
The inspection decides the treatment level, from spot treatment to a full treatment finished with a thick white encapsulant that makes any regrowth easy to see. Each level comes with a written warranty. See how our attic mold treatment levels and warranty work.
We fix the moisture source. Air sealing the ceiling below the attic is usually the strongest step. Then we correct and balance the ventilation, vent exhaust fans outdoors, and fix roof leaks.
The goal is an attic that stays dry.
