Regular inspections after winter are recommended to catch early signs of freeze-thaw damage.

If you have a claim, get a written assessment from a licensed Ajax roofing contractor to support your claim.

Roof size in sq metres is the primary factor determining roofing costs in Ajax, ON. Contractors measure from the ground level by calculating your home's footprint and adjusting for roof pitch. A steeper roof covers more sq metres and costs more to replace. To get accurate quotes in Ajax, you'll need to know your approximate roof size in sq metres.

If ice dams form, contact a roofing professional in Ajax immediately to assess damage. Regular maintenance and snow removal can also help prevent this issue during Ajax's heavy snow season.
