6 Common Insects That Wreak Havoc on Your Roof

Your roof is designed to protect your home from the elements, but sometimes the biggest threats can be the tiny, destructive insects that can quietly compromise its strength. 

We’ll explore six common insects that can wreak havoc on your roof, and how you can protect your home from these small but destructive pests.

1. Termites

Termites are notorious for their ability to destroy wooden structures. These pests can burrow through wooden roof decking, beams, and rafters, weakening the structural integrity of your home. Once they establish a colony, they cause damage before you even realize they’re there. Schedule regular termite inspections, especially if you live in a termite-prone area. You must also ensure that any wood in your attic is treated with termite-resistant coatings.

Here are some signs to watch out for:

• Hollow-sounding wood when tapped
• Termite droppings (small pellets)
• Mud tubes on exterior walls or beams

‍

2. Carpenter Ants

While carpenter ants don’t eat wood like termites, they still pose a serious threat by tunneling through it to create nests. They typically target areas of your roof that are damp or decaying, making them especially dangerous after a roof leak. Keep your roof well-maintained, repair leaks promptly, and replace any decaying wood to discourage carpenter ants from nesting.

Some signs to look for:

• Piles of sawdust near wood structures
• Rustling sounds in walls or ceilings
• Winged ants around the attic or roofline

‍

3. Wasps

Wasps may not damage your roof directly, but they often build nests in sheltered spots under eaves, soffits, and roof overhangs. Over time, a large nest can cause structural damage to the roof or gutters. Regularly inspect your roof and eaves for nests, and remove them as soon as they appear. It’s best to call a professional pest control service for safe removal.

Check your roof if you see: 

• Wasp nests hanging under eaves or gutters
• Frequent wasp activity near your roofline

4. Silverfish

Silverfish are often found in dark, damp areas of the home, including attics and roof spaces. While they don’t directly damage the structure, they feed on organic materials like paper, insulation, and glue, which can compromise your roof’s interior components over time. Keep roof spaces dry by addressing leaks and improving ventilation to make the environment less appealing to silverfish.

Some signs that these insects are damaging your roof:

• Yellow stains or holes
• Shed skins
• Droppings
• Visible insects

5. Powderpost Beetles

Powderpost beetles are a lesser-known but equally destructive insect for your roof. These beetles lay their eggs in wood, and when the larvae hatch, they burrow through it, leaving behind tiny exit holes and powdery dust (hence the name). Use treated wood when repairing or building your roof, and consider applying insecticide to vulnerable areas if you’re in a high-risk area for powderpost beetles.

It is time to check your roof if you see: 

• Small holes in wooden beams or roof decking
• Fine, powdery dust near wood structures

6. Carpenter Bees

Carpenter bees are large, solitary bees that bore holes into wood to create nests. They typically target unpainted or untreated wood, making roof eaves, fascia boards, and shingles ideal locations for them to drill. Painting or staining wooden structures can discourage carpenter bees. If you spot holes, make sure to seal them immediately.

Here are some obvious signs to look for:

• Perfectly round holes in wooden roof structures
• Sawdust beneath holes
• Bees hovering near eaves or fascia boards
