Our Process

Our Process 

1. Free Roof Inspection & Estimate

• Schedule a no-cost roof assessment. We photograph shingles, underlayment condition, flashings and attic ventilation.

• Provide detailed proposal listing “Asphalt Shingle Roof Toronto,” “TPO Flat Roof GTA,” “Emergency Roof Repair Toronto,” etc.

2. Permit & Material Selection

• Valencia LCD obtains all necessary permits (City of Toronto Building Permits, Mississauga, Brampton, etc.).

• Choose roofing system: architectural shingle, metal, TPO/EPDM, or green roof options. Select color, texture and warranty package.

3. Roof Tear-Off & Deck Inspection

• Remove existing roofing down to sheathing. Inspect roof deck for rot or damage—replace sheathing as needed.

• Clean and dispose of all debris in tarps; recycle metal and shingles where possible.

4. Underlayment & Flashing Installation

• Install ice-and-water shield in eaves, valleys, and around penetrations.

• Lay high-quality synthetic underlayment to protect sheathing from moisture.

• Install new step flashing, chimney flashing, vents and proper drip edges.

5. Shingle or Membrane Installation

• Asphalt Shingles: Lay shingles with manufacturer-approved starter strips, proper nail pattern and staggered courses.

• Metal Panels: Secure standing seam panels to engineered clips—ensure thermal movement allowance and watertight seams.

• TPO/EPDM Membranes: Heat-weld or mechanically attach seams; install tapered insulation if needed for drainage.

6. Finishing & Cleanup

• Install ridge caps, soffit vents, and roof jacks for attic ventilation.

• Nail and seal all penetrations.

• Thorough site cleanup: magnetic sweep of yard, haul debris for recycling, final roof inspection with homeowner.

Frequently Asked Questions

How long does a residential roof replacement take?

A typical asphalt shingle tear-off and re-roof in Toronto takes 2–4 days for an average single-family home (1,500–2,000 sq ft). Metal and flat roofs may take 3–5 days depending on deck repairs and weather.

Do I need to move my car during a roof installation?
Yes. Please move vehicles at least 15 ft away from eaves and downspouts to avoid falling debris and ensure safe access for dumpster and material staging.
What is the difference between TPO and EPDM flat roofing?
o TPO (Thermoplastic Polyolefin): Heat-welded seams, highly reflective, energy-efficient, more expensive upfront. o EPDM (Ethylene Propylene Diene Monomer): Rubber membrane, cost- effective, seam adhesives, good for complex roof shapes with multiple penetrations.
How can I prevent ice dams on my roof?
Proper attic insulation, venting, and ice-and-water shield underlayment in eaves. We also offer heat cable installation to prevent damming along eaves—contact us for a seasonal inspection.
