The Consequences of Ponding Water on Your Flat Roof
Flat roofs are a common choice for many commercial buildings, but one of the biggest challenges that can occur with this design choice is ponding water. While seemingly harmless, this can lead to severe complications and costly damage if not properly addressed. In this article, we delve into the nature of ponding water on flat roofs, its causes and implications, and most importantly, how Seal Roofing can protect your flat roof from its devastating effects.
Understanding Ponding Water
One common issue many commercial flat roofs face is ponding water—something that requires immediate attention to prevent severe structural problems. Ponding water on a flat roof refers to the pooling or accumulation of water in a particular location on the roof, typically a low point, for more than 48 hours after rainfall. This is due to inadequate drainage systems or a poor roof design that does not help with drainage.
Causes of Ponding Water on Flat Roofs
Ponding water on a flat roof can come from several underlying problems, often related to the installation, material quality, or roof design. One frequent cause is improper installation of the roofing materials or drainage system. This creates low spots where water tends to accumulate, leading to ponding. It could also be because of sagging roof decks, lack of a proper slope, or extensive damage that could hinder proper water flow.
Signs of Ponding Water
Standing water or a visibly wet surface long after rainfall is usually the first indication. You might also notice vegetation growth around the area or discoloration on your roof. Another sign could be a low spot or sagging area. A professional roofing contractor like Seal Roofing can identify these signs during preventative maintenance or a roof inspection.
The Effects of Ponding Water on Your Flat Roof
Leaving ponding water unchecked on your flat roof can have several consequences for your property, from structural damage to increased liability. Here are some of the most common effects of not tending to ponding water on your commercial flat roof.
Long-term water ponding causes severe structural damage to your flat roof system. The water adds unnecessary weight, resulting in sagging and eventual structural failure. In some instances, you might need a structural engineer to assess the damage and provide remedies, which could include an extensive roof replacement process.
Degradation of Roof Materials
Ponding water has a damaging effect on roofing materials over time. Whether it’s rubber, foam, or a roof membrane, the materials can be quickly ruined by water, leading to roof leaks. It might also cause the growth of algae, which can block drainage paths and lead to more ponding water.
Growth of Algae and Vegetation
When water remains stagnant for long periods, it creates a conducive environment for algae and vegetation growth. This growth not only affects the look of your roof, but can also result in more water accumulation, roof leaks, and material deterioration.
Increased Liability Due to Slip Hazards
In commercial settings, ponding water poses a significant slip hazard. This can be a legal liability for the property owner, as failure to stop water pooling could lead to hefty penalties or even lawsuits.
Implications for Your Roof Warranty
In many instances, ponding water could void your roof warranty. Most manufacturers define in their warranties that their products are not designed to withstand long periods of standing water, hence the need for positive drainage. Therefore, it’s crucial to prevent ponding water with a well-designed roof, proper maintenance measures, and prompt commercial roof repairs.
Neglecting ponding water on your flat roof can cause many problems and should be resolved as soon as possible. Seal Roofing offers commercial repairs that can restore your roof to its former glory.
Preventative Measures for Ponding Water on a Flat Roof
Preventing ponding water on a flat commercial roof is essential to maintain its integrity and longevity. Here are some ways to address and prevent ponding water:
- Proper Roof Design: Make sure the initial roof design has adequate slope and drainage systems to direct water toward drains and scuppers.
- Regular Inspections: Conduct frequent inspections to identify and address ponding water issues early.
- Improve Drainage: Clean and maintain drains and gutters, removing debris that can obstruct water flow.
- Use Tapered Insulation: Use tapered insulation systems to create slopes that direct water towards drains.
- Proper Maintenance: Regularly maintain your roof membrane and repair any punctures or damage.
- Prevent Vegetation Growth: Remove and prevent the growth of vegetation that can trap water.
- Improve Roof Coating: Apply reflective and cool roofing coatings to reduce heat absorption and minimize thermal expansion/contraction.
Preventing ponding water is essential, as it can lead to leaks and costly damage. Routine maintenance, inspections, and appropriate design considerations are key to avoiding these issues on flat commercial roofs.
