The soffit and fascia on your home serve multiple purposes, including:
- protecting the attic space from bird, bat, insect, and rodent invasion
- protecting the attic space from water damage during high-wind storms
- helping to regulate the ventilation in your home's attic space
- adding positively to the architectural style of your home
For these reasons, it is vital that you address any mold problems that you find on your home's soffit and fascia areas while they are still small and before they have time to grow and further damage the wood. Follow these steps to remove mold from your home's wooden soffit and fascia areas:
Step 1: Find the Water Source and Resolve the Underlying Moisture Problem
Mold requires moisture for it to grow and thrive. When you find mold growing on your home's fascia and soffit areas, then there is always an underlying moisture problem. Water damage on soffits and fascia boards is generally caused by one of two problems:
- a leaking roof
- malfunctioning rain gutters
Before you can rid your home of mold for good, you must fix the leaking roof or the rain gutters to prevent the area from growing mold again shortly after you remove it.
Step 2: Kill the Mold Colonies with a Bleach Solution
Once you have fixed your roof or rain gutters, then you should clean the mold area using a solution of household bleach mixed with water. For the best results, spray the solution on the soffit and fascia areas and let it sit for a little while. Any areas that remain black in color need to be sprayed again until they disappear. After you no longer see any mold, wash the area with some clear water to remove the remaining bleach.
Step 3: Sand or Replace Moisture-Damaged Wood
Once the wood has completely dried, you should either remove the damaged wood and replace it or sand the wood down into healthy wood. If you can flake off the wood fibers, then you need to replace the wood. If the damage is just to the outside of the wood, then you can sand it down with some sandpaper into the healthy wood.
Step 4: Paint the Wood to Protect It
Finally, once the wood is sanded or replaced, then you need to paint it to match the rest of the fascia and soffit areas of your home. You should only use an exterior-grade paint, as it will protect the wood against the elements. For more information about soffit and fascia, visit Metalworks Canada Ltd.
