Attic Condensation or Roof Leak? How to Understand Winter Ceiling Stains
A ceiling stain that appears without a rainstorm can be puzzling. Water is getting somewhere it shouldn’t, but there hasn’t been any rain to explain it. During colder weather, moisture can come from inside the home as well as outside. Warm, moist air that reaches a cold attic can leave condensation or frost on surfaces. […]
Can Your Roof Replacement Wait Until Spring? What to Check Before Winter
An aging roof can leave you with an uncomfortable decision in November.

Why Is My Flat Roof Leaking Where It Meets a Wall?
A flat roof leaking where it meets a wall is often caused by damaged flashing, deteriorating sealants, failed membrane connections or moisture entering through nearby masonry.

Flat Roof Repair in Toronto: What Affects Cost and How Long It Takes
Flat roof repair in Toronto can be a relatively small job when the damage is isolated, or a much larger project when water has reached insulation, decking, flashing or several areas of the membrane.

Roof Repair After A Storm In Toronto: What To Do & Who To Call
