Additionally, surrounding trees blocked sunlight to the house. This allowed moisture to settle into the roof without evaporating, allowing mold to grow. If the moisture had been exposed to direct sunlight, it would have evaporated and mold would not have been able to grow.

To remedy the water drainage afflictions, larger gutters with gutter guards were installed to accommodate the required flow capacity and to keep clogging to a minimum. Drain pipes were attached to all the downspouts to keep the water away from the house. Drip edges were installed along the roof edge, and all the damaged exterior wood was replaced.
