10 of the Most Common Problems With Commercial Roofs
Commercial roofs come with their own set of issues, partly because of size and also because they are often flat, which makes them more prone to issues like standing water. Here are 10 of the most common problems we find with commercial roofs:

  • Roof leaks
  • Debris in the roof membrane
  • Standing water or ponding (there should not be any standing water 48 hours after the most recent rain)
  • Punctures in the roof from mechanical contractors
  • Loose, buckled or damaged flashing
  • Gaps or cracks in caulking around roof penetrations (vents, antennas, skylights, HVAC units, etc.)
  • Missing domes on drains
  • Cracks, blisters, punctures or alligatoring on the roof’s surface
  • Cracked masonry caps or parapets
  • Defective, damaged or missing masonry joints

Other Issues to Look For
Often, commercial roofs are used for storage overflow, particularly for extra construction materials. If this is the case, the materials should be removed and stored elsewhere to reduce wear and tear on the roof’s surface.

In addition, look for vegetation growing on or in contact with the roof, and remove it. Debris from gutters and drains can cause water damage and leaks.

Why Maintenance Is Important
If the first clue that the roof is leaking or damaged is a call from a tenant or your facilities manager, the options are likely to be costly and limited. However most of these problems can be spotted with a regular maintenance inspection, which can actually save you money in the long run.
