A flat roof can be a suitable choice for many homes and businesses, but it has potential issues to consider. The main concern is standing water, which occurs when water remains on the roof for over 48 hours due to poor drainage or low spots. This can damage roofing materials over time. Burrage Roofing in East Moline, IL, has over 30 years of experience addressing these flat roof issues, providing reliable solutions to keep your roof in good condition.
Understanding Ponding Water on Flat Roofs
Ponding water happens when water does not drain well from the flat roof. This is often because of the wrong design or problems in how the roof is made. When water pools sit on the roof after heavy rain, they can be a hidden problem for how long the flat roof will last.
These water pools can cause different problems. They can break down the roofing materials, make algae grow, and even cause roof leaks. Building owners in the Midwest need to know about this roofing issue to keep their flat roofs safe, especially when the weather is bad.

What Is Ponding Water and Why Does It Happen?
Ponding water refers to standing water on a flat roof that remains for over 48 hours. It typically accumulates in low areas and worsens when drainage systems fail, indicating inadequate water flow.
Several factors can cause ponding water, such as building settlement or poor roof slope. Blocked drains or scuppers also prevent water from draining away, leaving pools after rainfall.
Homeowners and building owners, especially in the rain-prone Midwest, must address these water pools. Failing to do so can damage roofing materials and compromise the building’s structure.
How Ponding Water Impacts Flat Roofs in the Midwest
Flat roofs in the Midwest are more susceptible to standing water due to variable weather. Building owners often encounter ponding from heavy rain and melting snow, which can hinder drainage.
Prolonged standing water can lead to significant issues, such as deterioration of roofing materials and sagging roof decks, increasing the risk of leaks. The added weight over time may weaken the roof structure.
If not addressed, these risks could jeopardize safety and result in costly repairs or premature roof replacement. Burrage Roofing offers tailored solutions for Midwest weather, ensuring roofs remain safe from ponding, leaks, and damage.
Main Causes of Ponding Water on Flat Roofs
Ponding water on a flat roof typically results from poor design and ineffective drainage. Blocked or improperly installed drains prevent water from flowing off the roof, while insufficient slope causes pooling in low areas.
Building owners should consult a structural engineer to identify and resolve these issues. Improving roof design, ensuring proper slope, and enhancing drainage can significantly mitigate pooling, even in low spots. Effective drainage and design will extend your roof’s lifespan and performance.
Drainage Issues and Blocked Roof Drains
A flat roof needs a good drainage system to work well. If the rain gutters get clogged or if you do not take care of the drainage, water can build up on top. This pooling can happen in low spots because the water has nowhere to go. When the drainage system does not help water move off the roof, these low spots fill up and cause ponding.
Poor Roof Design and Structural Settling
Flat roofs with design flaws often lead to water pooling. A slight slope is essential for proper drainage, but older designs or poor craftsmanship may lack this feature. Deck deflection can exacerbate the issue, making it difficult to prevent water accumulation in low areas.
As buildings age, foundation settling can alter the roof’s slope. Even if it was initially designed correctly, low spots may develop over time, resulting in permanent water retention.
To mitigate long-term water issues, Burrage Roofing recommends implementing corrective designs. Raise the low areas and inspect the underlying structure to ensure durability.
Problems Caused by Ponding Water
Stagnant water on a flat roof can lead to leaks, damage to roofing materials, and vegetation growth. Prolonged pooling accelerates the breakdown of materials like membranes.
Excessive water can weaken the roof deck, adding weight that may cause sagging. Burrage Roofing’s repair services protect your flat roof from leaks and damage, ensuring its integrity.
Accelerated Roof Deterioration and Leaks
Roofing materials aren’t designed to hold standing water. When water accumulates on membranes, they deteriorate faster, compromising their waterproofing ability. Over time, this pressure can lead to leaks.
Small leaks in your flat roof signal potential issues. If left unaddressed, they can worsen, allowing water to infiltrate insulation and the substrate beneath the roofing, causing significant damage.
Burrage Roofing employs durable materials and specialized repair techniques for flat roofs, ensuring your property remains protected from leaks caused by standing water.
Vegetation Growth and Roof Deck Damage
Standing water on flat roofs promotes vegetation growth, leading to serious issues for the roofing system and underlying structure. Excess moisture encourages mold and algae development, compromising roofing materials’ integrity. This organic growth diminishes aesthetics and adds weight, increasing risks to stability.
Prolonged pooling can cause deck deflection and moisture penetration, resulting in potential leaks. Building owners should be vigilant, as compromised insulation may require costly repairs or full replacement. Timely intervention ensures the roofing system’s longevity and durability against the elements.
