THE SCOPE
Commercial Living & Green Roofs in Oakville & the GTA
Landscape above occupied space
A living roof is a layered building system, not simply planting placed on a roof. Establish whether the aim is an extensive planted surface or an occupied amenity terrace, then coordinate access, vegetation, loading and maintenance with the design team.
Protect the roof assembly
Structural review, membrane compatibility, drainage, root protection and interfaces around penetrations need specialist coordination. Clarify who provides each component, who tests the waterproofing and how future repair access is maintained.
Plan for operations
Plant establishment, irrigation strategy, inspections and replacement access affect the project after opening. Toronto’s current guidance requires a building permit for new green roofs and material alterations. Confirm the applicable process and any incentive conditions before committing the construction programme.
A clear scope. A considered budget.
Begin with the intended result and a budget range. We establish the work to include, the options to compare and the responsibilities of the project team before the construction scope is finalized. Design helps reserve space, resolve connections and identify cost drivers while changes are still on paper.
Pricing depends on the property, access, quantities, selected systems and specialist work. Your written proposal should distinguish construction, design, permits, taxes and optional additions. Availability and the delivery team for specialist services are confirmed during project assessment.
What we review before work begins
- Saturated loads and structural review
- Membrane and drainage responsibilities
- Safe access and maintenance plan
- Permit requirements for the address
Start with the property address, photographs, any available survey and a description of your priorities. The approvals and inspection stages are confirmed for the actual design.
Your questions, answered.
Is a planted roof the same as an occupied rooftop terrace?
No. An occupied terrace introduces additional circulation, guard, furniture and use considerations. The building and landscape teams need to coordinate the complete proposal.
Can this be part of a complete landscape project?
Yes. Discuss the complete brief at the start so access, levels, materials and specialist work can be coordinated in one schedule. The agreed proposal sets out which services Milton Stone provides and which require a named specialist.
Reference: Toronto green-roof permit guidance ↗. Product specifications and local requirements must be confirmed for the selected scope.
