Owner Patricia Airdrie is on-site for every project, ensuring quality from tear-off to final inspection.
Signs You Need a Roof Replacement
- Age — Most asphalt shingle roofs last 20-25 years in Ontario’s climate. If yours is approaching that age, it’s time to plan.
- Widespread shingle damage — Curling, cracking, or granule loss across large areas means the shingles have reached end of life.
- Multiple leaks — If you’re patching leaks every season, the underlying deck or underlayment may be compromised.
- Sagging roof deck — A sagging roofline indicates structural damage that can’t be fixed with surface repairs.
- Visible daylight in attic — If you can see light through your roof boards, moisture is getting in too.
- Moss or algae growth — Persistent organic growth traps moisture and accelerates deterioration.
Roofing Materials We Install
We work with premium materials from industry-leading manufacturers to suit your home, budget, and Ontario’s demanding weather:
- Asphalt shingles (IKO, Owens Corning, GAF) — The most popular choice for Ontario homes. Excellent value, 25-50 year warranties depending on the product line, and wide colour selection.
- Metal roofing — Standing seam and metal shingle options that handle heavy snow loads and last 40-60 years. Ideal for Simcoe County properties that deal with lake-effect snow.
- Euroshield rubber roofing — Made from recycled tires, these shingles are virtually indestructible against hail and impact damage. A great option for areas prone to severe weather.
Our Replacement Process
- Free on-site assessment — We inspect your current roof, attic ventilation, and decking to determine the full scope of work.
- Detailed written quote — Materials, labour, timeline, and warranty details — all upfront with no hidden costs.
- Complete tear-off — We strip the old roofing down to the deck, inspect for rot or damage, and replace any compromised sheathing.
- Ice and water shield — We install ice and water barrier along eaves, valleys, and penetrations — critical protection for Ontario’s freeze-thaw cycles.
- Professional installation — New underlayment, drip edge, shingles, flashing, vents, and ridge cap installed to manufacturer specifications.
- Final inspection and cleanup — We use magnetic sweepers to catch every nail and leave your property spotless.
- Warranty registration — We register your manufacturer warranty and provide our own workmanship guarantee.
