Roll Out the TPO Carpet: Roof Membrane Inspection and Maintenance

roof membraneCommercial roofing has its own specific set of issues when compared to the residential sector. Trying to figure out the best time to for repairs is common to both, but commercial roofing brings other considerations into the equation. Residential roofing usually deals with shingling or shakes and the deterioration of wood or asphalt. Most commercial jobs involve flat roofs with a strong polymer membrane as the base for structure.

But a roof membrane needs to be maintained, just like any other material. Knowing the proper time to inspect and repair the membrane on a commercial roof could mean the difference between catching that solvable problem before it grows and finding the key fault that necessitates a full roof replacement.

When to Inspect the Roof Membrane

Having a professional come in every week to inspect a commercial building’s roof membrane is overkill, a waste of money, and basically unrealistic. On the other hand, waiting several years between inspections doesn’t make sense, either, though it is probably the most common scenario. There is a happy medium between the two, and options in how to schedule these inspections.

  • Roofing companies recommend that a commercial roof should be inspected twice a year. Once in the spring to ensure that any damage from the winter months can be dealt with right away, and the other in the winter to anticipate and plan for any major renovations to take place during the dryer spring or summer months.

Extra inspections can be made if the property undergoes particular stress (larger storms, heavy rain or snow, etc.) to ensure that there are no pressing issues that go unnoticed.

Damaged Roof Membrane: What to Look For

There are a number of different kinds of damage to detect when it comes to roof membranes, all of which cause their own unique problems. Some examples are:

  • Blistering: Movement of trapped air due to temperature shifts where air gets in and causes spongy and deteriorated portions of the membrane. These blisters can burst, causing punctures that let in water and other elements that could harm the overall structure.
  • Ridging: The bunching of a membrane around the insulation joints or drain areas, depending on the type of roof membrane used, due to moisture condensing underneath.
  • Splitting: Spongy and long cracks along the membrane due to harsher conditions such as freeze-thaw or even poor installation.

All of these can cause a roof to fail and must be dealt with if found during a regular roof membrane inspection. Finding and experienced and reliable roofing company to thoroughly inspect and maintain the membrane is a top consideration for any commercial property owner.
