Can Wasps Cause Roof Damage

Although wasps often build nests beneath roof eaves or slide under shingles to reach the attic through cracks and crevices, most of their damage is minimal. While a colony may be able to crack and split wood to enter the attic, this is often a sign of damage. It is important to repair this damage so that future infestations are prevented.

Roof-Dwelling Wasps

Many types of wasps nest under the roof’s eaves, such as paper and yellowjackets. Their nests can be attached to the roof’s underside by attaching their ball-shaped papery nests. The nests do not cause any damage. Once the colony is gone in the autumn, it’s possible to remove and clean out the nest. The nest often leaves no trace. You can leave an abandoned nest if it is too large to be removed. Nature will remove it. Wasps do not reuse old nests.

  • The roof’s eaves are a favorite spot to nest for many types of bees including yellowjackets as well as paper wasps.
  • You can remove the nest from the site and clean up any traces left after the colony has scattered.

Get Inside

Yellowjackets and paper wasps nest in walls and attics. You may be able to see tiny cracks or openings from the outside, but they can get into your home through these small holes. A damaged roof can leave the inside of your home at risk. Weathered shingles may allow water to enter the home, warping boards or providing entry points for wasps. You should inspect the roof for any signs that wasps may have built a nest within it. You can see where they are coming from by watching them. Although they are not likely to cause damage, nests built by wasps may be quite difficult to remove.

  • Yellowjackets and paper wasps are common nesting places for these insects.
  • Weather-worn shingles may allow water to enter, and can warp boards or provide entry points for wasps.

Prevention

You should seal any openings that you find for wasps into your home. Check other parts of your roof to make sure there is no similar damage. Some cracks can be caulked, but boards and/or shingles may have to be replaced. Consult a professional if the damage appears to be severe. If nests have been constructed under the eaves of the house, you can use a wasp-specific pesticide and it should be applied in the late evening. After there has been no activity, cover the nest with a plastic bag and tear it apart where possible. If there is any remaining nest pieces, this will usually remove them all.

  • You should seal any openings that you notice for wasps through your roof.
  • Place a bag of garbage over the nest once there has been no activity. Then, remove the bag from the area it was attached.

Roof damage from insects

Nesting insects can cause roof damage. These nests must be completely removed to avoid further damage. Honeybees, which are social and beneficial insects like the honeybees, will build a colony near your garden to ensure pollination. They can be mistaken for wasps as they are less aggressive. They are generally considered to be beneficial and will protect their nests. Bees make nests out of wax and honey. These nests can become brittle if they are not removed from the roof during the hot summer months. Honeycombs and wax that have melted will cause damage to the roof.
