Roofing and Exterior Contractor in the GTA
Pahals Construction handles roofing and exterior building work for homeowners and businesses across Toronto, Mississauga, Brampton, Markham, Vaughan, Richmond Hill, Oakville, Pickering, Ajax, Whitby, and Oshawa. Could be a full roof replacement or exterior repair work tied into a bigger renovation — either way, one project lead manages it from inspection through to final sign-off.
What We Do
- Roof Replacement — Full tear-off and replacement for roofs past their lifespan or showing widespread wear.
- Roof Repair — Targeted repairs for leaks, damaged shingles, or flashing issues without a full replacement.
- Eavestrough & Fascia — Installation and repair of eavestroughs, fascia, and soffit as part of a roofing or exterior job.
- Exterior Building Envelope Work — Siding, trim, and general exterior repairs that protect the structure, not just the roof.
- Storm & Wind Damage Repair — Assessment and repair work following storm damage, coordinated with insurance documentation where needed.
Why Roofing Isn’t Just About the Shingles
A roof problem is rarely just the shingles. More often it’s flashing that’s failed around a chimney or vent, an eavestrough pitched wrong and pushing water back up under the edge, or ventilation that’s letting moisture build up in the attic and quietly rot the deck from underneath. We inspect the whole system before quoting anything, because patching shingles over a flashing problem just means we’re back out here in a year fixing the same leak.
How the Process Works
- Roof inspection — checking shingles, flashing, ventilation, and deck condition, not just the visible surface
- Itemized estimate — repair vs. replacement laid out clearly, with reasoning either way
- Material selection — shingle type and colour matched to the home or building
- Installation — tear-off and replacement, or targeted repair, completed to code
- Final walkthrough — reviewing the finished work and warranty details together
