Roofing
If your shingles are nearing their age or are already beyond it, it's time to consider an upgrade! If you notice your shingles are curling or buckling, it's a clear sign of aging and weathering. Upgrading can prevent further damage to your roof! Missing shingles can allow water seepage in your home and cause extensive damage!
We love using OC Duration shingles as they stand up well to our fun Alberta weather! Unlike standard shingles, TruDefinition®DurationSTORM®impact-resistant shingles feature patented WeatherGuard®Technology. The integrated polymeric backing material of theWeatherGuard®Technology allows DurationSTORM®shingles to meet one of the industry's highest ratings for impact resistance, UL 2218, Class 4. They feature a Limited Lifetime Warranty*/‡‡ (for as long as you own your home) and a 130-MPH Wind Resistance Limited Warranty*. TruDefinition® Duration® Shingles are produced with StreakGuard™ Protection to inhibit the growth of airborne blue-green algae* that can cause unsightly dark streaks on your roof.
