Commercial Roofing FAQs

Straight answers to the questions London building owners and property managers ask us most.

How much does a commercial roof replacement cost in London?

It's priced per square foot and depends on the system, roof size, whether we tear off or recover, insulation, and roof access. There's no honest one-size number — that's why we do a free assessment and give you a written, itemized quote.

Should I repair or replace my roof?

If the membrane is sound and the issue is localized, we repair. If you're repairing the same spot repeatedly, the roof is near end-of-life, or the insulation is wet, a replacement is cheaper long-term.

TPO or EPDM — which is better?

TPO is reflective and lowers cooling costs; EPDM is a proven rubber membrane that excels in cold. It depends on your building — see our TPO & EPDM page.

Do you offer emergency roof repair?

Yes — 24/7 emergency response for active leaks, storm damage, and snow load across London and Middlesex County.

Are you insured, and is there a warranty?

Fully insured, WSIB-compliant, IHSA safety protocols. Installs carry manufacturer material warranties plus our workmanship warranty.

How long does a replacement take?

A few days to a couple of weeks depending on size, system, and weather. Large facilities are phased to keep you operating.
