Detecting Commercial Roof Damage

Even a quality commercial roof installed by the team at J National needs attention now and then to maintain its efficiency and spot potential issues before little problems turn into unexpected surprises. However, many business owners don’t consider commercial roof repair in Dallas, TX, until there’s a noticeable problem, such as a leak. If this includes you, read on for things you should pay attention to when looking to detect roof damage early to minimize the need for emergency roof repair.

Blistering or Bubbling

When water gets trapped under a roof, especially a flat commercial roof, the insulation swells. The result of this swelling is usually some degree of blistering and bubbling. If ignored, water damage may eventually lead to the following problems:

  • Serious damage to underlying roof structures
  • Plaster damage along exterior walls
  • Either obvious or hidden leaks
  • Increased potential for damage during storms from blown-off roofing materials that are already damaged by blistering or bubbling

Stained or Sagging Ceilings

Interior ceilings common in office, industrial, and business spaces may develop stains from slow leaks that have gone undetected. Roof leaks may also cause ceilings to sag or panels to fall down if damage is extensive.

Unusual Odors or Mold Growth

Odd odors in places that don’t get a lot of attention like storage closets could be a sign of a mold problem from a slow leak. Roof leaks may also cause mold to develop on ceiling panels, in corners, or along exterior walls. Pay particular attention to spots where air conditioning doesn’t circulate well.

Clogged Flat Roof Drains

Drains on flat roofs are meant to keep water from ponding during heavy rains. If roof drains are clogged, that means water is probably gathering on your roof. Even if evaporation takes care of most of it during hotter days, problems with drainage can damage surface materials over time, often to the point where water gets into spaces below the surface or damages the flashing around roof protrusions like air ducts and heating and cooling components.

Standing or Ponding Water

Issues with your roof other than clogged drains may also result in standing or ponding water. A common culprit is exterior downspouts that are partially or entirely blocked. Insufficient drainage can become especially problematic at times of the year when storms or heavy rains occur with greater frequency.

Plant Growth

Insufficient drainage sometimes results in plant growth on flat roofs, especially those on commercial facilities near tree-lined or wooded areas. Plant growth may also be a sign that parts of your roof have developed cracks where dirt and debris can accumulate. Add puddles of water to this mix and your roof could become “green” in a way that’s not beneficial. If plants are left to grow, the roots may cause further damage.
