Ponding water is a common issue that can lead to roof damage if left unaddressed. This problem often arises due to imperfections in the roof’s slope or poor drainage systems. In this article, we explore why ponding occurs and provide practical steps to resolve it.
Ponding water happens when water collects on a flat or low-slope roof due to inadequate slope or blocked drainage. This issue is more prevalent in areas like London, Ontario, which experience freeze-thaw cycles and heavy snow loads.
Freeze-thaw cycles can exacerbate ponding by causing ice dams that block gutters and downspouts, leading to water pooling on the roof.
Several factors contribute to ponding. These include incorrect or damaged roofing materials, improper drainage systems, and insufficient slope. In London’s climate, where heavy snowfall can accumulate, these issues are exacerbated.
Poor insulation can also affect the roof's overall performance by increasing heat retention during winter, which may cause ice dams and further blockages.

Regular inspections are crucial to catch ponding early. Look for signs such as water marks on the roof surface or around downspouts. If you notice standing water, it's important to address the issue promptly.
Significant water pooling can cause structural damage over time, leading to leaks and other costly repairs.
To fix ponding water, start by ensuring proper drainage. Clear any debris from gutters and downspouts. If the issue persists, consider adjusting the roof slope or installing additional drainage channels.
Our crews can evaluate your roof’s condition and recommend appropriate solutions such as membrane repairs, re-grouting of flashing, or even a full roof replacement.
Regular maintenance is key to preventing ponding. Clean gutters twice a year and check for any signs of damage or wear on your roofing materials. Keeping an eye on the roof’s overall health can save you from future issues.
Consider installing new roofing systems that are designed to handle local weather conditions better, such as TPO, EPDM, or modified bitumen.
