Check My PropertyFrequently Asked Questions
Do I need a permit for a new roof in Hamilton?
Re-roofing with the same materials (e.g., replacing asphalt shingles with asphalt shingles) typically does not require a building permit. However, structural changes, adding skylights, changing roof shape, or switching to heavier materials (e.g., from shingles to slate) generally require a permit.
Do I need a permit to add a skylight?
Yes, adding a skylight typically requires a building permit since it involves cutting into the roof structure and may affect weatherproofing, fire ratings, and energy efficiency requirements.
Can I remove layers of old shingles without a permit?
Removing old shingles and replacing them with the same type generally does not require a permit. However, if you discover structural damage during removal that requires repairs, those repairs may need a permit.
