Frequently Asked Questions About Roofing in London

Get answers to common questions from London homeowners.

How much does a new roof cost in London?

The average cost for a new roof in London ranges from $5,000 to $15,000 depending on the size of your home, roofing materials chosen, and complexity of the job. Asphalt shingles are the most economical option ($3.50-$5.50 per sq ft), while metal roofing costs more ($7-$12 per sq ft) but lasts significantly longer. Contact us for a free estimate.

What's the best roofing material for London's climate?

For London's climate with cold winters and hot, humid summers, we recommend architectural asphalt shingles or metal roofing. Both handle temperature fluctuations well and resist ice dam formation. Metal roofing excels in snow shedding and longevity (50+ years), while quality asphalt shingles offer excellent value and typically last 25-30 years.

How long does a roofing project take in London?

Most residential roofing projects in London take 1-3 days to complete, depending on the size and complexity of your roof. A typical single-family home (1,500-2,000 sq ft) can often be completed in one day with our experienced crew. Larger homes or complex roof designs may take 2-3 days.

Do I need a permit for roofing work in London?

Yes, roofing work in London requires a building permit from the City of London. We handle all permit applications for you as part of our service. This ensures your project meets all Ontario Building Code requirements and London municipal bylaws. Permits typically take 5-10 business days to process.

What warranty do you offer on roofing in London?

We provide a lifetime written workmanship warranty on all our roofing installations in London. Additionally, the materials come with manufacturer warranties ranging from 25 years to lifetime, depending on the shingles you choose. Our warranty is fully transferable if you sell your home.

Can you help with insurance claims in London?

Absolutely! We work with insurance companies daily and can assist with your insurance claim for storm damage, wind damage, or hail damage. We'll document the damage, provide detailed estimates, and work directly with your insurance adjuster to ensure you get fair coverage.
