Most homeowners understand the significant damage that can happen to a roof in the wake of an extreme weather event or other natural phenomena. But your roof can also suffer damage from risk factors you either fail to notice or neglect to address. The following are three issues that pose a serious risk of danger to your roof.


Moss may accumulate on a roof that is shielded from the sun for a significant amount of time. Homes that are located under tree cover may have to deal with the growth of moss more than once or twice over the years. If you live in an area of the country with frequent rain and damp conditions, you are also likely to deal with moss on your roof more than individuals living in other parts of the country.

Once the moss is present on your roof it becomes a sponge that will soak up rainwater. This situation, if left unattended, can lead to a water buildup that can threaten the structural integrity of the roof.

If a small amount of moss is present on your roof, you can attempt a do-it-yourself removal. However, a roof that is completely covered with moss, or one that has had moss present for an extended amount of time, should be seen by a professional.

Diseased Trees

A second area of concern for your roof is a tree in your yard that has contracted a disease. Diseased trees are falling hazards that pose a risk to both people and property, including your roof.

Wounds to a tree that results from pruning, injury from a lawn mower, or wind damage can provide an opening for fungus to enter the tree. The fungus then decays the tree to provide itself with nutrients. The fungus reproduces itself by forming spores on limbs, trunks, or roots. Large limbs are then at risk for falling and trees with rotted roots may fall over completely in heavy winds.

A tree in advanced stages of fungus infestation is a serious risk and likely cannot be saved. You are better advised to seek tree removal in these cases. At the very least, you should seek the opinion of a professional.


Mold can develop and spread quickly across your roof when conditions are wet. Once the mold is present it can cause serious damage to the shingles on your roof. Mold that attaches itself to support beams can also weaken the structure of the roof.

If mold is detected early enough, it is not difficult to clean this nuisance from the surface of your roof. However, if fast action is not taken, the mold from your roof can become an issue throughout your home.

There are a number of factors that affect the appearance and health of your roof. It is important to inspect your roof on a daily basis to provide yourself with early detection of potential roof hazards. The above-mentioned hazards are something with which all homeowners should become familiar.
