When planning a flat roof replacement in Toronto, one of the most common questions is: How long will it take? While no two projects are exactly alike, understanding the general timeline helps set expectations, avoid surprises, and plan for potential disruptions to your home or business.
1. Pre-Inspection and Quoting (1–3 Days)
Before any work begins, a roofing contractor will inspect your roof to assess its condition, measure dimensions, and determine if a full tear-off is required. They’ll also check for moisture damage, structural concerns, and insulation levels. A quote is typically provided within a day or two after the inspection.
2. Permits and Scheduling (3–7 Days)
In Toronto, some flat roof replacements—especially those involving structural changes, insulation upgrades, or multiple layers—may require permits. Your contractor will advise if this applies to your project and help handle the paperwork. Scheduling is then coordinated based on crew availability and weather conditions.
3. Removal of Existing Roof (1–2 Days)
If your roof has more than one layer or shows signs of water damage, a full tear-off will be necessary. This phase includes stripping away all old roofing material, exposing the deck, and disposing of debris. Larger or more complex roofs may take a little longer.
4. Deck Inspection and Repair (1 Day)
Once the old materials are removed, the roof deck is inspected for damage. Any rotten or soft areas are replaced or reinforced before installation begins. This step is essential to ensure the longevity of your new flat roof.
5. Installation of Insulation and Membrane (1–3 Days)
Insulation is installed first—either flat or tapered, depending on your drainage needs. Then, the membrane (TPO, EPDM, or modified bitumen) is applied using adhesive, mechanical fasteners, or heat welding. Flashing and sealing follow immediately to ensure waterproofing.
6. Final Cleanup and Inspection (1 Day)
After installation, the crew will remove all leftover materials, sweep the area, and conduct a full walkthrough. A professional contractor will test drainage, confirm seams and flashing are secure, and provide you with warranty documentation.
