The Construction Gap: A Common Entry Point for Wildlife

If you've noticed signs of unwelcome critters like squirrels or rats in your attic or walls, the culprit could be the notorious "construction gap."

What is the Construction Gap?

The construction gap refers to small openings that are left where roof lines meet siding or overhangs during the building phase. These gaps occur when roofing materials like shingles don't fully connect to a home's exterior finishing. Gaps are often 1-2 inches wide and can provide an easy entrance point into voids and interior spaces for wildlife like:


  • Gray squirrels
  • Flying squirrels
  • Birds
  • Rodents

Once inside, these pests can cause considerable damage. Squirrels can tear up insulation for nesting, birds and rodents gnaw on wires or beams and all wildlife will leave behind nesting materials and waste, creating unsanitary conditions.

Why Does the Construction Gap Occur?

Small construction gaps happen due to improper installation or aging structures:

  • Shingles not positioned flush to exterior walls during roofing
  • Siding/brickwork not installed snugly against the roofline
  • Settling of the home over time
  • Warping of exterior materials

Often gaps are too small for homeowners to notice. But a 1/2-inch opening is all a squirrel needs to squeeze through and enter an attic.

Risks If the Construction Gap is Not Sealed

Ignoring openings along roof lines can lead to chronic wildlife problems, property damage, and health/safety issues:

  • Persistent access for squirrels, raccoons, rats, mice, and other nuisance wildlife
  • Extensive damage as animals chew, gnaw, burrow, and tear up insulation
  • Foul odors and spread of diseases from pests and waste
  • Nesting materials blocking gutters and potential water damage
  • Risk of electrical fires if wildlife begin to chew on wiring

It's critical to get the construction gap professionally sealed to keep wildlife out and prevent destruction.

How to Seal the Construction Gap

Sealing the construction gap requires expertise. At Breda Pest Management, our licensed professionals:

  • Thoroughly inspect all roof lines and exterior joints to locate gap entry points
  • Use heavy-duty materials like galvanized steel, copper mesh, or industrial caulk for permanent seals
  • Install one-way doors so remaining animals can leave but not re-enter
  • Safely remove any trapped wildlife and sanitize affected areas
  • Provide homeowners with long-term guarantees against future wildlife entry
