Bat Exclusion and Roofline Sealing – Pickering

Job Overview

Location: Pickering, Ontario
Structure: Large detached two-storey residential home
Problem: Bat activity reported in the attic during early morning hours
Service: Humane bat removal and roofline exclusion
Visits: Three

Summary

We completed a three-visit bat exclusion service on a large detached home in Pickering after the homeowner reported attic activity consistent with bats. Our team conducted a full roof inspection, installed one-way bat doors at confirmed entry points, completed targeted exclusion work along the roofline, and returned for final removal and confirmation once activity had ceased.

Background / Property Context

The home is a large two-storey structure with multiple roof planes, dormers, and intersecting rooflines. These architectural features create natural gaps and transitional areas that can be used by bats to access attic spaces, particularly along drip edges and fascia transitions.

Customer Concern

The homeowner reported hearing wildlife activity in the attic during the morning hours. Due to the timing and nature of the sounds, bat activity was suspected, and an inspection was requested to identify entry points and determine appropriate next steps.

Inspection & Findings

During the initial exterior inspection, our technician Grant performed a full roofline assessment. Several potential access points were observed along the roof edge and fascia areas. A primary entry point consistent with bat access was identified. No interior inspection was required at this stage.

Cause Analysis

Bats commonly access attic spaces through narrow gaps along roof edges, drip lines, and fascia boards. On this structure, overlapping roof sections and aging roofline materials created suitable openings. These conditions, combined with elevated roof height and low disturbance areas, made the location attractive for roosting.

Treatment / Removal

A humane, non-lethal bat exclusion process was followed. One-way bat doors were installed at the confirmed entry points, allowing bats to exit the attic naturally while preventing re-entry. All work was completed in accordance with seasonal and humane wildlife handling standards.

Exclusion & Repairs

In addition to the one-way doors, approximately eight feet of roofline along the drip edge was reinforced using galvanized steel mesh. This mesh was secured to prevent future access while maintaining airflow and roof function. Sealant was applied where appropriate to close secondary gaps once bat activity had ceased.

Outcome & Confirmation

On the final visit, the homeowner reported no further wildlife activity. The one-way doors were removed, all exclusion materials were inspected, and entry points were permanently sealed. A final inspection confirmed the integrity of the exclusion work, and no additional bat activity has been reported since completion.

Technician Notes

  • Visit 1: Exterior roof inspection completed. Primary bat entry point identified. Additional work required due to roof complexity.
  • Visit 2: Two bat one-way doors installed. Eight feet of drip edge excluded using galvanized steel mesh.
  • Visit 3: No further activity reported. One-way doors removed, sealed, and exclusion inspected.

Work was carried out by Grant with attention to roof safety, humane wildlife practices, and long-term exclusion durability.
