Flat roofs are a popular choice for many commercial and residential buildings. Their sleek design and efficient use of space make them a preferred option for modern architecture. However, like all roofing systems, flat roofs are susceptible to specific damages over time. In this comprehensive guide, we’ll delve deep into the causes of these damages and offer expert solutions to ensure the longevity of your flat roof.

The Phenomenon of Roof Alligatoring

One of the most common issues with flat roofs is alligatoring. This term refers to the appearance of cracks on the roof’s surface that resemble the skin of an alligator. The primary cause of alligatoring is prolonged exposure to the sun. Over time, the sun’s intense UV rays can dry out the membrane or coating of a flat roof, leading to cracks. As the roof ages, these cracks can become more pronounced, especially if left untreated.

Effects of Temperature Fluctuations:
Extreme temperature changes, from the scorching sun to snow and even the building’s internal heating and cooling systems, can exacerbate these cracks. The continuous expansion and contraction due to temperature variations can lead to the formation of new cracks and worsen existing ones.

Blistering: Another Common Issue

Blistering is another prevalent problem in membrane roofing systems. Unlike alligatoring, where cracks form a distinct pattern, blistering results in bubbles forming underneath the roof’s membrane.

Root Causes:
Blisters are primarily caused by pockets of air or moisture trapped between the layers of the roof’s membrane or between the membrane and the roof deck. When the sun heats the roof, these pockets expand, stretching the membrane. In extreme cases, the membrane might crack due to excessive pressure.

Indicators That Your Roof Needs Attention

  • Water Seepage: If there’s visible water damage due to cracks in your roof, it’s a clear sign that your roof requires immediate attention.
  • Widespread Alligatoring: If the alligatoring pattern is evident across a significant portion of your flat roof, it’s an indicator that the roof might need replacement.
  • Professional Recommendation: If a reputable roofing company in Columbia MD, like Kanga Roof, suggests a replacement after a routine inspection, it’s wise to heed their advice.

Proactive Measures for Flat Roof Maintenance

  • Debris Removal: Regularly clean your roof of leaves and other lightweight debris. This not only helps in spotting potential issues but also ensures the longevity of your roof.
  • Edge Inspection: Ensure that the edge flushing around the roof is securely fastened. Loose or missing pieces can lead to leaks.
  • Ponding Check: Use a water hose to check for water puddling in certain areas of the roof. Persistent ponding can weaken the roof structure.
  • Inspect Protrusions: If there are pipes or other objects protruding through the roof, ensure they are surrounded by flanges to prevent leaks.
  • Drain Examination: Ensure that the drains on your flat roof are not blocked. Regularly pouring water can help ascertain their functionality.
