A Thoughtful Full Roof Replacement on a Two‑Storey Home in Markham
A complete renewal addressing leak history, ageing materials and the homeowner’s desire for long‑term performance and refined curb appeal.
- 1
Initial survey and safe staging
A full on‑site assessment documented decking condition, chimney and valley details, and roof penetrations. We set up scaffold protection, debris chutes and tarps to protect landscaping and neighbouring properties in Markham and adjacent Richmond Hill, then scheduled work during a forecast window with minimal precipitation.

Removal and substrate repair
We performed a complete tear‑off down to the sheathing, removing old shingles, felt and flashings. Damaged OSB was replaced with APA‑rated sheathing; fasteners were upgraded where needed and the deck inspected for proper slope and drainage to ensure the new assembly would sit on a sound substrate.

Underlayment and ice‑water defence
Following best practices, we installed a peel‑and‑stick ice and water shield along eaves, valleys and around penetrations to meet local wind and ice dam risks. Over the full deck we applied a 30‑lb synthetic underlayment with high‑temperature ratings to improve tear resistance and reduce wrinkling in Ontario’s variable temperatures.

Premium roofing system and flashings
For longevity and refined appearance we selected laminated architectural shingles (laminated fiberglass‑reinforced) with a Class A fire rating and 130+ mph wind rating where required. All flashings were upgraded to 0.7 mm (24‑gauge) galvanized or stainless steel, with cricket and saddle work at the chimney and step flashings integrated into the new underlayment.

Ventilation and finishing details
To address attic moisture, we balanced intake and exhaust by installing continuous ridge ventilation and supplementing with low‑profile soffit vents where appropriate. Final steps included gutter guards, thorough cleanup with magnet sweep and homeowner walkthrough to review care, warranty and documentation.
Frequently Asked Questions
How long does a full roof replacement take on a two‑storey home?
Most full replacements on homes of this size are completed in two to four days of active work, depending on decking repairs and weather. Tear‑off, repairs, underlayment and shingle installation are scheduled consecutively, with additional time added if custom flashing or masonry work is required.
How disruptive will the project be to daily life?
There is noise during tear‑off and nail guns during installation, and you should expect limited driveway access while we stage scaffolding and materials. We manage waste, protect landscaping and keep neighbours informed to minimise disruption for homeowners in Markham and surrounding communities like Vaughan.
When is a full replacement necessary versus a repair?
A full replacement is advisable when shingles show widespread failure, when multiple leak points exist, or when decking and underlayment have deteriorated. For roofs nearing the end of typical asphalt shingle life, replacement provides better long‑term value than repeated spot repairs.
Do you account for local code and seasonal factors?
Yes — we follow Ontario Building Code principles and factor in Markham’s seasonal weather patterns, scheduling the work in favourable windows to reduce the risk of moisture intrusion during the job. We also detail ventilation and flashing to meet local performance expectations.
