Homeowner Warning Guide for Chimney Flashing

Ontario homeowners often notice roofing problems only after a leak appears inside the home. This page explains how chimney flashing works, what can go wrong, and how to think about the issue before requesting a roofing estimate or quote.

Homeowner Warning Guide

A good roofing estimate should describe what will be inspected, what materials are being used, what will be replaced, and whether ventilation, flashing, and roof edges are included in the scope.

This topic matters because where masonry, metal flashing, and roof materials must work together. Homeowners should pay attention to counter flashing, step flashing, cricket design, mortar joints, and water diversion when reviewing roof condition or comparing roofing quotes.

What Homeowners Should Check

Start with the visible roof area, then check the attic if it is safe and accessible. Look for staining, soft decking, blocked airflow, loose materials, rust, cracking, lifted edges, or signs that water is moving behind the surface layer.

If the issue is visible, repeating, or connected to interior moisture, it is worth requesting a roofing quote before the damage spreads.
