Moss Growing On Wood Siding

Whenever you see moss growing on wood siding, there is a very good chance that this area is located in the shade, for most or all of the day.

In order for moss to grow, it's going to need plenty of shade and moisture. If you really want to get down to the bottom of the problem, you're going to need to find out where the moisture is coming from before you complete the repairs.

The roof could be a big culprit in a situation like this. Moisture that accumulates on the roof in the early morning, will drip off of the roof, onto the concrete and bounce back onto the wood siding.

Another symptom of moss rolling on your wood siding would be someone using a water hose to clean the concrete off, regularly. There is a very good chance that anyone who was cleaning the concrete with water from a garden hose can easily spray the lower areas of the wood siding.

Once these areas are wet and they remain in the shade for most of the day, the moisture has plenty of time to penetrate the wood siding and provide a nice home for moss or mold to accumulate.

Home Repair Tip: Clean the wood siding with TSP first and if the moss isn't coming off, you could try chemicals like bleach or stronger chemicals that you can purchase at your local home improvement centers. Once this area dries, you can repaint it and you're done.

You've got to solve the moisture problem first. You can do all the cleaning and repainting that you want, but if this area remains moist, there's a good chance that you're going to be repairing the siding again, it's just a matter of time.
