Shrubs, trees or plants too close to the house can cause siding to be scraped or mechanically damaged when the wind blows. They can also prevent air and sunlight from drying wet siding. This can lead to moss, mold or rot. Trees too close, if tall enough, can overhang the roof and fill the gutters with leaves or needles. Large branches can scrape against the roof. Large, dead branches may fall, damaging the roof, gutters, siding or windows. Large trees close to the house may have roots that block or collapse sewers, or, in extreme cases, push in the foundation wall. Shrubs or trees too close to the house are the result of poor landscaping decisions or a lack of maintenance.
Check for damage where there is vegetation close enough to the house to have an effect. Often the only way to see if there has been any impact so far is to squeeze behind the plants. Look for scratching or denting, or mold and rot. Check horizontal surfaces carefully, and be aware of which side of the house you are on east and north sides tend to be more prone to moss and mold.
