What We Do

Roofing, from ridge
to eavestrough.

From full re-roofs to a single leaking valley — every job gets the same attention, the same crew standards, and the same cleanup your neighbours keep mentioning in their reviews.

01

Re-Roofing

Complete tear-off and replacement of your existing roof with premium fiberglass shingles, finished in clean, straight courses.

02

Roof Repairs

Leaks, storm damage, missing shingles, chimney flashing — repaired promptly and matched to your existing roof.

03

New Construction Roofs

Precision roofing for newly built homes, installed right the first time so it protects for decades.

04

Attic Insulation

Stop paying to heat the sky. Upgraded attic insulation keeps winter heat in your home — free insulation quotes.

05

Skylight Installation

Bring daylight into your home with professionally installed skylights, sealed and flashed to last.

06

Skylight Repair & Replacement

Fogged, cracked or leaking skylights repaired or replaced without disturbing the roof around them.

07

Sun Tunnel Installation

Natural light for hallways and interior rooms where a full skylight won’t fit.

08

Roof Ventilation & Eavestrough Cleaning

Balanced attic ventilation for a longer-lasting roof, plus eavestrough cleaning to keep water moving away from your home.

10Year Warranty

Our workmanship is guaranteed for ten years.

A roof is one of the largest investments you’ll make in your home. Don’t wait for a ceiling stain to find out how it was installed. We’re bonded, insured, our crews carry fall-safety training and WSIB coverage — and we’ll still be here, years after the ladder comes down.

Get Your Roof Checked
The Craft

Honest advice.
Careful hands.

We tell every homeowner the same thing: ask questions, get more than one quote, ask for references — and be wary of the cheapest number. Good roofing isn’t a mystery. It’s the right materials, installed carefully, by people who’ll answer for the work years later.

  • ✓Owner on every job — Christian meets you, quotes it, and stays on-site.
  • ✓Detailed written estimates — options explained, questions answered.
  • ✓Respect for your property — protected gardens, minimal disruption.
  • ✓Thorough cleanup — the crew leaves; the mess leaves with them.
