Cedar roof replaced with architectural shingles in Burlington
Removed old cedar shakes, upgraded deck and underlayment, installed Class A architectural shingles for better performance and lower maintenance.

1. Full tear-off and site prep
We removed the cedar shakes down to the sheathing. All old nails, flashings and felt were stripped. Material was loaded into a roll-off bin via a debris chute; labour crews kept the driveway and sidewalk clean. We inspected rafters and sheathing for rot as we worked.

2. Repair and re-deck where needed
Damaged sheathing panels were replaced with 19 mm (3/4") plywood to match building code stiffness recommendations. We sistered rafters where framing showed loss of bearing and fastened new deck with ring-shank nails to resist uplift in high winds common in the Toronto timezone region.

3. Underlayment, ice-and-water and ventilation
We installed a self-adhering ice-and-water shield (butyl-based membrane) in eaves, valleys and around penetrations to meet local best practices for Lake Ontario-influenced freeze-thaw cycles. Over the field, we used a synthetic breathable underlayment rated for asphalt shingles. Ridge and soffit ventilation were verified and upgraded where attic airflow was inadequate.

4. Flashings and metalwork
All step flashings at walls and counter-flashings around chimneys were replaced with 24-gauge galvanized steel, dressed and sealed. New lead-free chimney cap flashing and metal valley liners were installed where valley geometry required. We used ice guard at eaves to extend protection beyond typical manufacturer minimums in shaded areas.

5. Shingle installation and cleanup
We installed Class A architectural (laminated) asphalt shingles — fiberglass mat base with an SBS-modified asphalt coating — using manufacturer-specified starter strips and high-temp roofing nails. Hip and ridge received matching capped shingles. Final cleanup included magnetic sweep for nails and a post-installation inspection with homeowner walkthrough and digital photos for records.
Frequently Asked Questions
How long does a full cedar-to-shingle conversion take?
A typical two-storey full tear-off in Burlington runs three to five days, depending on roof complexity and required deck repairs. Weather windows matter — we avoid starting major tear-offs when extended rain or heavy freeze-thaw is forecast.
How disruptive is the work to daily life?
We stage equipment to minimize interference and use debris chutes to keep the yard tidy. Expect some noise during demo and nail guns during installation, but crews work set hours and coordinate with homeowners to protect landscaping and outdoor living spaces.
When should a cedar roof be replaced rather than repaired?
If more than 25–30% of shakes are split, cupped, or the attic shows recurring moisture stains, replacement is usually the right call. Also replace when decking rot is present or when the homeowner wants improved warranty and less maintenance.
Will the new roof affect insurance or resale in Burlington?
Upgrading from cedar to modern architectural shingles often improves perceived durability for insurers and buyers. We provide documentation and manufacturer specs by email so you can present clear records if needed.
