What if we bust a myth for you right away? Here it goes –
Myth: Ponding water on a flat roof is normal and doesn’t cause damage.
Fact: Standing water can weaken your roof’s structure, leading to leaks and premature failure. Studies show that water ponding for over 48 hours can reduce a roof’s lifespan by up to 40% (National Roofing Contractors Association). Addressing these issues quickly is essential to protecting your property. If you’re facing drainage problems, leaks, or need roofing repair service San Antonio, here’s what you should know.
Why Do Flat Roofs Develop Ponding Water?
Unlike shingle roofing, flat roofs have minimal slope, making drainage a challenge. Several factors contribute to water buildup, including:
- Clogged drains and gutters – Blockages prevent water from flowing off the roof.
- Poor installation or design flaws – Incorrect slope or insufficient drainage leads to water pooling.
- Roof material wear and tear – Aging membranes lose their ability to repel water effectively.
- Heavy rainfall or snow accumulation – Excessive moisture can overwhelm the roof’s drainage system.
How to Fix Ponding Water on a Flat Roof
If your flat roof is collecting water, these expert solutions can help:
1. Improve Drainage Systems
- Ensure roof drains, scuppers, and gutters are clear of debris.
- Install additional drains in low spots to enhance water flow.
2. Tapered Insulation Systems
- Adding a sloped insulation system can redirect water toward drains.
- This method is ideal for both residential roofing solutions and commercial roofing solutions.
3. Reinforce Roofing Membranes
- Single-ply membranes like TPO, EPDM, and PVC offer excellent water resistance.
- If your existing membrane is damaged, consider a recoat or a full replacement.
4. Apply a Roof Coating
- Silicone or acrylic coatings provide a seamless, waterproof barrier.
- This is a cost-effective way to extend the life of your flat roof.
Addressing Flat Roof Leaks: What You Need to Know
If water ponding is left unchecked, leaks become inevitable. Here’s how to handle them:
- Inspect Flashing and Seams – Damaged or improperly sealed seams can be the source of leaks.
- Patch Small Cracks Immediately – Use commercial-grade sealants to prevent further water infiltration.
- Consider a Torch Down Roofing Process – This method provides a durable, watertight seal, making it a great choice for long-term protection.
- Schedule Professional Inspections – Experts such as roofing repair service San Antonio can identify weak spots before they turn into costly repairs.
