Roofing FAQs — Hamilton & Golden Horseshoe
How long does a roof replacement take in Hamilton?
Most residential roof replacements in Hamilton are completed in 1–2 days. Larger homes or those with complex roof lines may take up to 3 days. Bosani Roofing gives you a clear timeline during your free estimate — no surprises.
How do I know if I need a full replacement or just a repair?
If your roof is 20+ years old, has widespread shingle failure, or has been repaired multiple times, replacement is usually the smarter investment. If damage is isolated to one section and the rest of the roof is sound, a targeted repair may be all you need. We give honest assessments — no upselling.
Is Bosani Roofing licensed and insured in Ontario?
Yes. Bosani Roofing is fully licensed, WSIB certified, and carries complete liability insurance on every job — residential and commercial. You are fully protected from day one.
What roofing brands do you install in Hamilton?
We work with GAF, CertainTeed, IKO, Landmark, and Owen Corning. As a GAF Certified Installer, we can access extended manufacturer warranties not available through uncertified contractors.
Do you offer free roofing estimates in Hamilton?
Yes. All estimates are free, detailed, and no-obligation. Call (905) 745-0818 or fill out the form above and we'll respond within 24 hours.
Does homeowner's insurance cover roof replacement in Ontario?
If the damage is caused by a covered peril — storm, hail, fire, or falling debris — most Ontario home insurance policies will cover roof replacement. Bosani Roofing can help document the damage for your insurance claim.
What is a GAF Certified Installer and why does it matter?
GAF Certified status places a contractor in the top 3% of roofers in North America. It means Bosani Roofing has met GAF's standards for installation quality, insurance, and professional conduct — and can offer you enhanced warranties that other contractors can't provide.

Most residential roof replacements in Hamilton range from $8,000 to $18,000 depending on roof size, pitch, material selection, and decking condition. Bosani Roofing provides detailed, itemized written quotes before any work begins — no hidden costs.
