Is It Time to Replace Your Roof?
Most asphalt shingle roofs in the Hamilton area last 18–25 years — often less on exposed Mountain, Stoney Creek, and lakefront homes where wind and freeze-thaw cycles hit hardest. If your roof is approaching that age, watch for these signs:
- Shingles curling at the edges, cracking, or losing granules (check your downspouts for granule buildup)
- Multiple leaks, or repairs becoming a yearly event
- Sagging roof lines or spongy decking underfoot
- Daylight visible through the attic boards
- Neighbours with same-age homes getting reroofed
- Dark streaks, moss, or widespread discolouration
Not sure? A free inspection settles it. If a repair will do the job, that's what you'll be told — replacement is only recommended when it's truly the smarter spend.
What a Roof Replacement Costs in Hamilton
For a typical detached Hamilton home, a full asphalt shingle replacement generally runs $8,000–$18,000+, depending on:
- Roof size and pitch — steeper and larger roofs cost more in labour and safety setup
- Tear-off — number of existing shingle layers to remove and dispose of
- Materials — entry-level vs. architectural shingles, or metal roofing (typically 2–3× shingle cost but lasting 50+ years)
- Decking condition — rotted plywood discovered during tear-off must be replaced
- Complexity — skylights, chimneys, valleys, and dormers add flashing work
Your free quote itemizes all of this in writing, so you can compare apples to apples with any other bid.

- Magnetic nail sweep of your lawn and driveway, full cleanup
- Manufacturer's shingle warranty plus contractor workmanship warranty
How Long Does It Take?
Most Hamilton homes are reroofed in 1–2 days, weather permitting. Larger or more complex roofs may take 3–4. The crew arrives with all materials, protects your landscaping, and leaves the property clean.
