The Impact of Weather on Your Roof

Our homes are our sanctuaries, providing shelter and safety from the elements. The roof is one of the most critical components of our homes that withstand the constant barrage of weather elements. 

As Ottawa residents, we are all familiar with the full spectrum of challenges that our climate can bring. Scorching sun, fierce winds, torrential rain, heavy snowfall, and sudden hailstorms are just a few examples of the weather we often encounter. 

It’s essential to recognize these conditions’ impact on your roof to keep it in optimal condition and ensure your home’s long-term safety and efficiency. For over 30 years, Stewart Roofing has been one of Ottawa’s most trusted providers, ensuring your home remains safe no matter the weather outside.

Sun & Heat on Your Roof

Surprisingly, the seemingly harmless sun is one of the most underestimated culprits in the damage. However, consistent exposure to ultraviolet (UV) rays and extreme heat can contributeDamaged shingles on Roof from heat. significantly to the deterioration of your roof, particularly when it comes to asphalt shingles. 

As the shingles are exposed to sunlight over time, they can become dried out, brittle, and more prone to cracking or curling. Roofs made from wood, metal, or other materials may also be vulnerable to sun damage if not adequately protected.

To mitigate this issue, it’s crucial to incorporate proper ventilation. Attic ventilation can be vital in reducing heat retention, helping to balance the temperature and keeping the home cooler. Be sure to ask your expert for advice on the best types of vents for your specific design.

Wind on Your Roof

Another significant cause of damage is wind. High winds, which are typical during stormy weather or seasonal transitions, have the potential to devastate your roof’s integrity. 

As gusts of wind blow across the surface, they can cause shingles or other materials to lift or tear. This damage leaves the underlying roof deck exposed and more susceptible to leaks.

Once a section has been compromised by wind, ensuing gusts can dislodge even more shingles, creating a domino effect that results in extensive damage. 

To protect your home from wind-related damage, consider investing in materials with higher wind resistance ratings and adopting effective fastening techniques during installation.


Rain is one of the primary drivers of roof deterioration. When shingles become loose or damaged, water can infiltrate beneath them, leading to leaks and subsequent damage. This damage can manifest as stained ceilings, mould growth, and even structural issues caused by wood rot.

To prevent water damage from rain, it’s essential to inspect your roof regularly and repair or replace any damaged shingles promptly. Additionally, it’s vital to maintain your gutter system, periodically cleaning and ensuring the downspouts are transparent, allowing water to flow freely away from your home. 

By addressing rain-related issues early on, you can minimize costly repairs and structural damage to your home.

Snow & Ice

As Ottawa residents, we’re no strangers to finding our homes buried beneath a thick blanket of snow. Heavy snowfall can cause many problems for our roofs, particularly regarding weight and iceIce Dam on Roof in gutter accumulation. 

Flat or low-pitched roofs are especially susceptible to weight issues; the prolonged accumulation of snow can exert immense pressure on the structure, leading to potential collapse.

When snow melts due to heat escaping from the interior of your home, it can cause ice dams to form at the roof’s edge. These ice dams prevent water from draining off, causing it to pool and exacerbate existing damage. 

Proper insulation and ventilation within your home will help to ensure an even temperature by reducing heat loss and minimizing the risk of ice dam formation.


While hail storms may occur less often than other weather events, they pose a legitimate threat to your roof’s lifespan and performance. A hailstorm can cause extensive surface damage to your shingles. 

It can remove the granular coating on asphalt shingles, essentially strip-mining them of their protective layer. This leads to accelerated weathering, reduced lifespan, and diminished aesthetic appeal.

In the event of a hailstorm, it’s important to inspect your roof for any damage and ensure that any repairs are done promptly to prevent further harm.


Maintaining the health and longevity of your roof involves understanding the detrimental effects of different weather conditions and taking preventative measures.
