Questions and Answers
My home insurance premium in London keeps climbing. Can a new roof actually lower my bill?
Yes, directly. With a regional insurance premium trend increase of 18%, insurers are aggressively pricing risk. While the IBHS FORTIFIED Home standard is a U.S. program, installing a roof that meets or exceeds its core principles—such as using enhanced high-wind attachments and impact-resistant shingles—signals reduced risk to Canadian underwriters. This demonstrable mitigation can lead to substantial premium reductions, offsetting a portion of the project cost over time.
I'm considering solar. Should I install traditional shingles now and add panels later, or go with solar shingles?
This is a lifecycle calculation. Traditional architectural shingles paired with rack-mounted panels leverage the Canada Greener Homes Grant and federal investment tax credit equivalent, offering proven efficiency and easier component replacement. Integrated solar shingles provide a streamlined aesthetic but currently at a higher cost-per-watt and with less flexibility. In 2026, the decision hinges on your 25-year energy cost projections and whether you prioritize system modularity or architectural uniformity.
A tree limb punctured my roof during a storm. How fast can a contractor get here to stop the water?
For an active leak, emergency tarping crews dispatch immediately. From a central staging area near Victoria Park, the route north via Highway 401 allows for a 35-45 minute response to most Old North addresses. The priority is a watertight seal with reinforced, code-compliant tarping to protect the interior and the plywood decking from catastrophic water intrusion until permanent repairs can be scheduled.
My attic feels musty. Could my roof's design be causing mold and ice dams?
Absolutely. On a standard 6/12 pitch gable roof, improper venting creates a host of issues. Inadequate intake at the soffits and exhaust at the ridge disrupts the thermal flow, leading to attic condensation, mold growth on sheathing, and winter ice damming that forces water under shingles. The 2012 Ontario Building Code, with 2024 amendments, specifies minimum net free vent area ratios; a balanced system is required for roof longevity and home energy efficiency, not merely an optional upgrade.
My London home's roof is original. Why is it failing now, and what should I expect to find?
With an average build year of 1974, your roof is over 50 years old, far exceeding the service life of architectural asphalt shingles. In Old North, decades of seasonal freeze-thaw cycles and UV exposure have degraded the shingle matrix and granule adhesion. The original 1/2 inch plywood decking, while standard for its time, may have experienced cumulative moisture damage from minor, undetected leaks, compromising its structural integrity for a new roof system.
My roof looks fine from the ground. Why would I pay for a high-tech inspection?
Traditional visual inspections miss critical sub-surface failures. Standard infrared thermography and drone imagery can identify trapped moisture within the shingle layers and decking, thermal patterns indicating poor insulation or ventilation, and lifted seal strips invisible from the ground. This diagnostic tech provides a complete system assessment, preventing you from investing in a re-roof over compromised plywood sheathing or addressing only superficial symptoms.
We get severe thunderstorms. What makes a roof 'storm-ready' for London's wind and hail?
Storm readiness is defined by your roof's ability to resist specific, quantified threats. London's 90-95 mph wind zone (ASCE 7-22) requires meticulous attention to shingle sealing strips, starter strip placement, and decking attachment. For the moderate hail risk, installing shingles with a UL 2218 Class 4 impact rating is a financial necessity; they are engineered to withstand 2-inch hail, preventing the costly granular loss and fractures that standard shingles suffer during the May-August peak storm season.
What are the legal and code requirements I must verify for a roof replacement in London?
You must confirm your contractor holds a valid license with the Ontario College of Trades and pulls a permit from the City of London Building Division. Under the 2012 OBC with 2024 amendments, this is not a cosmetic job. Code now mandates specific material upgrades, such as a continuous ice and water shield membrane in vulnerable eaves and valleys, and precise flashing details at walls and penetrations. These requirements exist to ensure the assembly meets the current wind-driven rain and durability standards.
