Your roof is one of the most important parts of your home—it protects your family, belongings, and structure from Ottawa’s unpredictable weather. Over time, however, even the best shingle roofs show signs of wear. 
Between freezing winters, heavy snowfall, spring thaws, and hot summers, roofing materials in our region face a lot of stress. Knowing when to replace your shingle roof can help you prevent water damage, energy loss, and costly repairs.
At Godfrey Roofing, we’ve assisted Ottawa homeowners in assessing, repairing, and replacing their roofs for decades. Our experienced team understands how local climate conditions affect roofing systems and when replacement is the most cost-effective choice.
Typical Lifespan of Shingle Roofs In Ottawa
One of the first questions homeowners ask is, “How long should shingle roofs last?” While the answer depends on several factors, most asphalt shingle roofs in Ottawa last between 15 and 25 years.
Premium architectural shingles or high-performance asphalt options may last longer, sometimes up to 30 years with proper maintenance. However, factors like installation quality, ventilation, weather exposure, and regular upkeep can all influence lifespan.
Our company installs high-quality shingles built to endure Ottawa’s temperature swings, but even durable materials eventually end their life. When granules wear off, shingles curl or crack, and leaks appear, it’s time to consider shingle roofs replacements rather than another repair.
Visible Signs That It’s Time for Shingle Roof Replacement
Regular roof inspections—especially after harsh weather—can help you spot shingle roofs problems early. Some warning signs are easy to see from the ground, while others require a closer professional look.
One clear indicator that your roof may need replacement is missing, curling, or cracked shingles. Shingles that are brittle or lifting away from the roof surface can’t effectively protect against moisture, leading to leaks and water damage.
You may also notice granules collecting in your gutters or around your downspouts. Granules protect shingles from UV rays; when they begin to fall off, the roof loses an important layer of defence.
Another red flag is visible sagging or uneven areas on your roof. This can signal deeper structural issues, such as rot or weakened decking caused by moisture infiltration. Dark streaks, mould, or moss growing on the surface can indicate trapped moisture or poor ventilation. Inside your home, water stains on ceilings, damp insulation, or peeling paint near the attic are often early signs of roof failure.
Damage from Ottawa’s Climate
Ottawa’s climate is particularly tough on shingle roofs. The city experiences extreme cold in the winter, humid summers, and frequent freeze-thaw cycles. These fluctuations cause shingles to expand and contract repeatedly, eventually leading to cracking or curling.
Ice dams can also form along eaves, forcing water under shingles and into the roof deck. Over time, this causes deterioration and leakage. High winds during storms can loosen shingles or tear them off completely, leaving exposed areas vulnerable to rain and snow.
UV exposure during the summer further weakens the materials, causing them to lose flexibility and protective granules. Our roofing team understands these conditions well and uses materials and installation techniques to handle Ottawa’s challenging environment.
Repair or Replace? Knowing the Difference
Homeowners often ask whether they can repair damaged areas instead of replacing the entire roof. Sometimes, spot repairs make sense—especially if the damage is minor and isolated. However, when more than a quarter of the roof shows signs of deterioration or leaks in multiple locations, full replacement is usually the more practical and long-term solution.
Repairs seem less expensive upfront, but can add up quickly if underlying problems persist. Our company always conducts a thorough inspection before recommending roof replacement. We look at factors like age, material condition, ventilation, and insulation to determine the best action. We’ll also provide clear estimates and timelines so you can plan confidently.
The Benefits of Replacing Your Roof at the Right Time
Replacing your shingle roof before major problems arise offers several key advantages. A new roof provides stronger protection against leaks, reduces maintenance costs, and improves energy efficiency by sealing your home more effectively.
It also enhances your property’s curb appeal and resale value—buyers in Ottawa often prioritize recently replaced roofs when evaluating homes. By investing in roof replacement proactively, you also gain peace of mind during harsh weather.
With modern materials and proper installation, your new roof can better withstand wind, snow, ice, and heat for decades. Our roofing team focuses on precision workmanship and high-quality products that deliver reliable performance year after year.
Preventive Maintenance to Extend Roof Life
Regular maintenance is essential to maximize its lifespan even after installing a new roof. Keeping gutters clear, trimming overhanging branches, and scheduling professional inspections every few years can prevent small issues from escalating.
After major storms, it is wise to check for missing shingles or damage around vents and flashing. Our company provides complete roof maintenance and inspection services in Ottawa.
We help homeowners identify potential problems early and perform targeted repairs that protect their investment. Proper ventilation and insulation are also critical for keeping moisture levels balanced and preventing premature shingle aging.
