Why Flat Roofs Leak and What to Do About It

by | May 24, 2023 | Flat Roofing, Roof Repair

Home and business owners often choose flat roofs for their low cost and ease of installation, but they come with their own set of maintenance issues. Why flat roofs leak is a concern for many. Unfortunately, one of the most common problems with flat roofs is leaking. In this blog post, we’ll explain why flat roofs are prone to leaking and offer tips for preventing roof leaks.

Extreme Weather

Extreme weather is a major cause of flat roof leaks. Understanding why flat roofs leak can be attributed to various factors such as high winds and debris that damage roofs, heavy rains seeping through poorly sealed seams or cracks, and hail sometimes causing punctures that allow water to leak in. If the roof is not adequately insulated and ventilated, the heat from the sun can cause it to warp and crack. In extreme cold, snow and ice buildup can add extra weight to the roof and cause it to cave in. To avoid these problems, select a roof that can withstand the local climate and have regular inspections to reveal any damage so you can have it repaired right away.

Poor Installation or Maintenance

When a flat roof has an installation or maintenance problem, it can quickly start leaking. If the roofer does not seal around flashings, lay out the roofing material properly, or the roof has other unaddressed weak points, it will be more prone to leaking. Additionally, rainwater can pool on the roof and cause damage from improperly maintained gutters and drains. Regular inspections and maintenance of flat roofs help identify and fix any potential problems before they become significant. For example, regularly check for exposed nails, loose flashing, and clogged gutters or downspouts.

Age and Wear and Tear

Age and wear and tear are typical reasons why flat roofs leak. Flat roofs, like any roof, experience damage over time because of their age and normal wear and tear. Heavy foot traffic, bad weather, and other factors lead to premature aging of the roof material and ultimately cause leaks. In addition, roofing materials such as asphalt shingles, metal sheets, and rubber membranes are susceptible to tearing and cracking due to their flexibility. Over time, these materials weaken and break down, allowing water to seep in and cause damage. Have an expert inspect your roof regularly to ensure it is in good condition and free from tears or cracks. Additionally, making repairs when needed helps extend the life of your flat roof and prevent costly repairs in the future.

Poor Quality Roofing Materials

The roofing materials’ quality also plays a role in the leaky nature of flat roofs. Substandard materials, as well as improperly applied or installed materials, contribute to leaks. In addition, these materials may not withstand harsh elements and might be more prone to wear and tear. For example, plastic sheeting is not as strong as other roofing materials, so it may be more prone to cracks and punctures, leading to a leak. On the other hand, quality materials are resistant to UV radiation and weathering, resilient, and waterproof.

How to Prevent Flat Roof Leaks

Prevention is the best cure for keeping your flat roof in top condition. Taking the right steps to ensure the proper installation and regular maintenance of your roof goes a long way toward keeping it leak-free for many years. Here are some tips on how to prevent flat roof leaks:

  • Start with quality materials: Investing in high-quality roofing materials is the key to a long-lasting flat roof. Use products designed specifically for flat roofs and suitable for the Texas climate.
  • Have the roof professionally installed: Proper installation prevents flat roof leaks. If you’re unfamiliar with flat roof installation, hire an experienced professional.
  • Inspect the roof regularly: Regular inspections are crucial for detecting problems before they become serious. Look for signs of damage, such as missing shingles, cracks, or broken seals.
  • Clear debris from the roof: Leaves and other debris can block drainage points, leading to ponding water, which may cause damage over time. Make sure you remove any debris on the roof regularly.
  • Patch up small problems quickly: Small issues, such as minor cracks or punctures, quickly develop into larger ones if they’re not taken care of promptly. Watch for signs of damage and patch them up as soon as possible.
  • Re-seal joints every few years: Joints and seams may become loose over time, so re-seal them every few years to prevent leaks.
