Roof leak repair that protects your home

Cost varies with the size and complexity of the leak, materials required, roof pitch and access, and whether secondary damage such as sheathing rot or insulation replacement is discovered. Other factors include the flashing types involved (step flashing, chimney counterflashing, metal valley pans), whether emergency tarping is needed, and timing relative to peak seasons. We assess the roof, document the issues, and provide an itemised written quote that separates material, labour and any recommended follow-up work so you can make an informed decision.

Simple flashing or shingle repairs can often be scheduled and completed within days, subject to weather and current workload, while complex jobs that require sheathing replacement or permit review may take longer. We prioritise active leaks for emergency tarping and temporary weatherproofing, then plan permanent repairs on a clarified schedule. The written quote includes an expected start window and time-on-site estimate.

Common materials include dimensional asphalt shingles, laminated architectural shingles, self-adhesive ice & water shield, synthetic underlayment, metal step and counterflashing, EPDM or neoprene pipe boots, and ice-protection membranes at eaves and valleys. We select materials to match existing assemblies and to meet Mississauga’s climate demands for freeze–thaw and wind resistance.

Minor repairs often do not require municipal permits, while work that replaces structural sheathing, changes roofline, or constitutes a full re-roof may trigger permit requirements and inspections. We outline permit needs in the written scope and, when a permit is required, provide documentation and coordinate with inspectors as part of the project.

Our workmanship guarantee covers the specific repairs we complete as described in the estimate, and product warranties depend on the manufacturer for materials like underlayments or metal flashings. We document both workmanship terms and transferable material warranties in the final paperwork so you understand coverage and process for any follow-up.

Clear access to the areas under the roof where work will occur, remove fragile items from attics if an inspection is part of the visit, and secure pets. We will protect landscaping, set up debris containment, and keep you informed by email about arrival windows and any preparations needed.

Different contractors may specify different scopes based on how thoroughly they inspect, the quality of materials proposed, the details of flashings and underlayment, and whether they include contingency for hidden damage. A detailed, itemised quote that explains assumptions and exclusions provides the best basis for comparison rather than selecting solely on lowest price.
