Commercial Roof Repair 101: Reasons for Repair

Commercial roof repair is a significant investment, one that typically includes a few repair bills over several years. If you are installing a new one, it is important to realize that some roofing problems are preventable, while others result from age and environmental factors. To help you plan for the maintenance of your building's roof, below is a list of the most common reasons why you can experience problems:

Poor Maintenance

When a roof is not maintained according to the specifications of the contractor, the quality of its materials typically Declines. Roof maintenance requires a regular financial investment, but not maintaining it could lead to more expensive repairs, and could necessitate a costly replacement. Immediately following an installation, the building owner should establish a maintenance contract to have it inspected and maintained on a regular basis.

Wind Damage

When wind blows over the edge of panels or shingles, it can create a partial vacancy that destabilizes them. Although wind damage is thought to occur during hurricane weather or tornado weather, it can also happen when winds reach a moderate intensity (roughly sixty miles an hour). Properly applied metal edge strips can prevent most types of wind damage.


All roofing materials periodically decline due to weathering. The rate of decline can be affected by several factors, including:

  • Whether the materials are organic or inorganic
  • The presence of environmental pollutants
  • The presence of airborne salt
  • Temperature fluctuation

A roofing contractor can tell you what materials respond best to the city's humid subtropical climate.

Poor Design

Poor design is a major cause of premature commercial roof repair and replacement. This is why building owners should only hire contractors who provide a manufacturer's warranty-a warranty that insures the workmanship of the installation, not just the installed materials.

Flashing Damage

Flashings are used to prevent water from infiltrating the seams where the roof surface meets projections such as chimneys and steam pipes. Flashings are usually the first part of a roof system to experience decline, and should be closely monitored through regular maintenance.

Metal Edge Strip Damage

Metal edge strips and gravel stops in aggregate-surfaced systems are used to cap the edges of smooth surfaced roofs to protect against wind damage. Over time, the strips can experience broken joints and splits in the striking felts at their edges. Raising the strips out of the water line, or providing an internal drainage system, can help prevent this damage.

Improper Mountings

When mountings are secured directly to the roof, penetrating its membrane, hard to repair leaks are the inevitable result. Unfortunately, many building owners install antennae, signs, and other rooftop projections without knowing this. If an improper mounting causes a problem, the mounting must typically be removed before the problem can be fixed.
