How Weather Affects Roofs in London & Southwestern Ontario

The weather in London and Southwestern Ontario can be harsh during certain weather conditions, especially for roofs. Your roof is the first line of defense for your home against the weather elements, including rain, snow, and strong winds. Therefore, it is essential to understand how the weather affects your roof to ensure its longevity and optimal functionality. In this article, we will discuss the various ways that weather can impact your roof in challenging weather conditions.

Weather May Damage Your Roof Over Time

Rain & Water

Repairing From Bad WeatherRain is the primary cause of roof damage in London and Southwestern Ontario. Excessive rainfall can lead to water damage, especially in the case of a roof leak. If not addressed promptly, the water can seep into the home’s structure and cause serious damage. During heavy rain, it is always advisable to check for signs of leaks, water damage, or shingle damage. Ensure that the gutters are clear and functioning correctly, and replace any missing or damaged shingles.

Snow & Ice 

Snowfall is relatively common during the winter months. Snow accumulation can put significant pressure on your roof, leading to damage or even collapse. It is essential to remove any excessive snow accumulation from your roof by using a snow rake or a professional snow removal service. This will prevent the snow from melting and freezing, which can result in the formation of ice dams. Ice dams can damage your roof’s shingles and gutters and cause significant water damage.

Wind & Severe Storms

High winds can be detrimental to your home’s roof. Wind can loosen or remove shingles, causing water and wind damage. It is essential to check for any missing or damaged shingles after a heavy windstorm. Additionally, trees and other debris can fall onto your roof during a storm, causing significant damage. Ensure that there are no overhanging trees or branches close to your roof that can cause damage during a storm.


The intense summer heat can cause your roof to expand and contract, leading to damage over time. It is essential to ensure that your roof has proper ventilation to allow for adequate airflow and prevent heat buildup. Additionally, the UV rays from the sun can cause shingles to fade and crack over time. 


Hail storms can cause significant damage to your roof, leading to leaks or water damage. Hail can cause dents, cracks, or holes in your roof’s shingles or metal panels, leading to reduced functionality and effectiveness. It is advisable to hire a professional roofer to inspect your roof after a hail storm to check for damage and recommend repairs or replacements.
