Commercial Roofing in LaSalle

The minimum fee for non-residential buildings

The base rate is the same for everyone, $9.80 per $1,000 of work. Only the minimum changes. The City sets that minimum at $491.70 for a commercial, industrial, institutional or mixed-use building, whatever the cost of the work.

The City places mixed-use buildings in this category without defining them. If your building combines a business and dwellings, have its classification confirmed at the permit counter.

The estimate submitted to the City must include all costs tied to the work, taxes included. The fees are non-refundable, and extra fees may be added if the building or its area is subject to heritage or special architectural standards.

This fee does not cover maintenance. According to the City, a simple roof repair in LaSalle needs no permit. The fee applies when the roofing is replaced, or when the work touches the insulation or structure.

The rule for roofs over 300 m²

In LaSalle, the total roof area decides which materials are allowed. Above 300 m², the City permits:

• a material that is white, painted white, or covered with a reflective coating or white gravel
• a material with a solar reflectance index of at least 56, confirmed by the manufacturer or by a professional's opinion
• a combination of these coverings

The City words this rule by area, not by use. A small storefront whose flat roof is under 300 m² falls under the list of ten new materials for smaller roofs.

Mechanical equipment on the roof

A commercial roof often carries air conditioning or ventilation units. The City provides that material requirements do not apply to the part of the roof taken up by mechanical equipment or by a deck.

The City page does not say how that part is measured, or whether moving a unit needs a separate approval. Bring these questions, with plans, to the LaSalle permit counter.

What a property manager should plan for

Here is what the City asks for, best gathered early.

• a power of attorney from the owner, if you act as an agent
• a letter of authorization from each co-owner or a resolution of the syndicate, if the building is a condo
• the quote or cost estimate grid, taxes included
• the certificate of location
• the materials technical data sheet, showing the solar reflectance index
• the building record (fiche-bâtiment)

If the roof covers leased premises, reread the leases or consult a legal adviser to know who decides and who pays.
