Metal vs Asphalt Roofing: 10 Reasons Metal Wins in Ontario
Ontario contractors push asphalt because it's easier to install and generates replacement revenue every 15 years. Here's the honest comparison that the asphalt industry doesn't want you to read.
Most roofing contractors in Ontario install asphalt shingles. Not because asphalt is the best material for Ontario's climate — it isn't — but because it's faster to install, requires less skill, and keeps homeowners coming back for a replacement every 15 years. VAH Construction installs only metal. Here's the honest comparison.

Frequently Asked Questions
Can I switch from asphalt to metal roofing on my Ontario home?
Yes. VAH Construction performs full roof replacement — complete tear-off of existing asphalt, deck inspection and repair, and new standing seam metal installation.
Do I need to replace my asphalt roof with metal, or can it be installed over top?
VAH Construction recommends full tear-off in most cases to inspect the deck, ensure proper ventilation, and install a correct thermal break underlayment. Roofing over existing material can trap moisture and void manufacturer warranties.
