As temperatures soar during the summer months, your roof takes the brunt of the heat—often without you even realizing the extent of the damage. The blistering sun, high humidity, and thermal expansion can silently compromise your roof’s integrity over time. Whether you own a home or manage a facility, it is essential to stay aware of early signs that indicate your roof is struggling in the heat. Proactive maintenance and timely commercial roof repair or residential intervention can prevent costly problems down the road. This blog explores the common summer roofing issues and highlights when to seek professional help for roofing projects.
Shingle damage and curling
One of the first visible signs of summer heat-related roof stress is damaged shingles. High temperatures cause roofing materials to expand, and prolonged exposure to the sun’s ultraviolet rays weakens the structural integrity of shingles. Over time, you may notice shingles starting to curl, buckle, or become brittle. These deformities make your roof more vulnerable to leaks and wind damage. In such cases, contacting a trusted roofing service provider in Ottawa ensures that repairs are made before the issue worsens.
Soft spots or sagging areas
Excessive heat and humidity can affect the underlayment and wooden structures beneath your roofing materials. If you observe soft areas or sagging spots when inspecting your roof, it may indicate moisture build-up or heat-induced weakening of support structures. Left unaddressed, this can lead to severe structural issues that require extensive commercial roof repair or full replacement.
Blistering on roof surfaces
Blisters or bubbles on roofing materials are another indication of heat damage. These form when air or moisture becomes trapped beneath the surface layer, often due to poor ventilation or defective materials. While blisters might seem minor at first, they can eventually crack and expose the inner layers of the roof to the elements, causing leaks and deterioration. An experienced roofing provider in Ottawa can assess the extent of the blistering and recommend proper repairs or resurfacing solutions.
Granule loss from asphalt shingles
Asphalt shingles are coated with granules that protect them from UV radiation. During summer, these granules can loosen due to high heat, strong winds, and heavy rain. Discovering a significant amount of granules in your gutters or downspouts often indicates that your shingles are beginning to deteriorate. This makes your roof less effective in reflecting heat and more prone to damage. In such cases, commercial roof repair may be necessary to restore energy efficiency and weather resistance.
Mold or mildew formation
High humidity levels in summer can also cause moisture accumulation, especially if your roof has poor ventilation. Mold and mildew thrive in such conditions, leading to dark patches or streaks on your roof. Not only do these microorganisms weaken roofing materials, but they can also spread into the interior of your home or building. Professional roofing in Ottawa services can inspect ventilation and recommend solutions to minimize moisture buildup and prevent health hazards.
Your roof is your first line of defense against summer heat, but it is also one of the most vulnerable parts of your property. From curling shingles and sagging surfaces to mold growth and blistering, summer brings a range of challenges that can silently compromise your roof’s health. Recognizing these signs early and seeking expert commercial roof repair is key to avoiding costly damage and maintaining your property’s safety. If you notice any of these red flags, reach out to professionals specializing in roofing in Ottawa to ensure timely inspection and reliable solutions.
