Drip Alert: Because the attic is not accessed regularly, homeowners often fail to realize it when they have a growing moisture and mold problem in their attic. Many of these stem from improperly ventilated dryers and fans. Be sure to check your attic regularly.

APA's Free From Mold ten point protection plan □ If it’s rusty and musty, you might have a host of moisture problems to contend with. Look for water stains on the underside of the roof, rusted nails, and discolored or mildewed sections on any surface. Call in expert advice if the situation appears severe.

□ Minor surface mildew can be wiped away using a chlorine-and-water solution. Be sure to dry the surface after you've finished. Painting over a mildew problem is unlikely to check the growth of the mildew.

□ Check that there is room for air to flow from the eaves (soffit vents) into the attic space and out the upper roof vents. Insulation should not block airflow by being pressed tight to the roof sheathing at the eaves or covering the eave or soffit vents. Attic baffles can be purchased at lumberyards to allow airflow.

□ Take time to inspect the amount of insulation in your attic. If you can see the wood framing between rows of insulation, as shown in the above image, you probably need more insulation.

□ Inspect bathroom, kitchen, and other exhaust ducts for leaks and blockages.

Because APA has no control over quality of workmanship or the conditions under which engineered wood products are used, it cannot accept responsibility of product performance or designs as actually constructed. Consult your local jurisdiction or design professional to assure compliance with code, construction, and performance requirements.
