3 Pests That Can Damage Your Roof

Roofs are susceptible to damage from various sources, such as hail and high winds, but one source that is often overlooked is pests. When insects and other critters take up residence on or near your roof, they are capable of causing significant harm. Here is a look at three pests every homeowner needs to be aware of.


You might not think of birds as pests, but there is no question that they can play havoc with your roof. For example, bird droppings contain an acid that is harmful to asphalt shingles and other roofing materials. In addition, birds often try to build nests in gutters, which can lead to your gutters being blocked by their nesting material and other debris. When this occurs, water that is unable to flow to the downspout can easily back up onto the roof and cause damage. Keep your gutters clear of any tree litter, such as leaves and twigs that might attract birds.

Also, birds may sometimes peck at roof shingles to gather material for their nests. This leads to the shingles being less effective at protecting your roof from the elements. Inspect your roof regularly for any signs of bird damage.


Squirrels are another pest that often causes roof issues. They can gain entry to the attic by passing through small holes in your fascia and soffits. They may also attempt to peel up a loose shingle and chew through the wooden roof decking.

One good idea to prevent squirrels from getting into your house is to have a roofing professional install a drip edge. The metal barrier is installed under the lowest row of shingles and makes it much more difficult for squirrels to try and chew through your roof. Trim back any branches that are overhanging the roof as well.


Honey bees are an issue for homeowners because they like to make their nests in dark spaces that are safe from any predators, which means bees are often attracted to attics. If honey bees get inside your roof, they can easily damage roofing materials such as roofing felt and tar, as well as insulation. Unfortunately, bees only need a gap of an inch or less to get inside your house and cause damage to the roof. The best way to prevent bee infestations is to have a roofer check your roof for any small gaps or cracks which could allow them entry.

If you find any roof damage caused by these three pests, or from any other source, contact one of the roofing contractors near you to repair the damage once the pests have been removed — such as Alpha Roofing & Siding.

The Life and Work of Roofers

Your home would not be a home without a roof. A good roof keeps the rain out, provides some insulation against sunlight, and does not easily become damaged when exposed to snow or ice. The roof was put in place by a roofer, who was probably one of the hardest-working people you'll ever meet. Who else can say they stand all day on a pitched surface and perform physical labor? Days as a roofer are long and hot, but we are all thankful for the work these professionals do. On this blog, you can learn more about roofers, their work, and their lives.
