How to inspect and maintain your commercial roof

Nov 19

Flat or low-slope roofing

Low-slope/flat roofs can cause severe weathering and brittle membranes. If this happens, your roof covering may be damaged.

Position any rocks to cover roof membranes that are missing, bare or damaged.

  • Make sure the roof membrane isn’t damaged.

Modified bitumen and built-up roofs should be inspected for cracks and bubbles, excessive wear around connections, tears, and punctures, as well as excess wear. Be aware that severe weathering can cause the loss or removal of embedded gravel and protective coatings.

  • Single-ply - Check for tears, worn seams, and seam failure. Watch out for unusually loose membranes and blisters in adhesive-, or glued-down systems.

  • A puncture in sprayed Polyurethane foam can cause the acrylic coating to peel off.

  • You should inspect metal panels for loose screws and worn rubber washers. They can lead to metal panels rusting over time. This is an anti-rust coating. Be aware of dents and divots.

Roof coverings for steep-sloped roofing

Check that the roof is not bowing or losing its shape. Also, consider these factors:

  • Inspect asphalt shingles for cracks or loose shingles.

  • Check for cracked or missing tiles in concrete and clay tiles.

  • You should inspect metal panels for loose screws and worn rubber washers. This can lead to metal panels deteriorating. This is an anti-rust coating. Be aware of dents and divots.

Roof drainage solutions

Remove any debris from your roofs, such as leaves, sticks, and construction debris. You should also remove any dirt or other granules stuck to gutters and roof drains.

Check your gutters regularly for any blockages that may be causing standing water.

Look for signs of deterioration in the perimeter flashing. High winds can cause roof collapse and water infiltration.

Equipment mounted to the roof

  • Check for corrosion on metal panels, screws, and flashing on curbs.

  • Inspect the equipment's connection with the curb. Look for signs of water damage and replace curbing if necessary.

  • All wires and straps must be securely fastened. You should have no slack. Refer to the manufacturer's instructions.

  • Be sure to inspect the area around roof-mounted equipment curbs for flashing. This could cause structural failure and water penetration.

  • Remove all debris from the area around and under the roof-mounted equipment.

  • Make sure all service panels have fasteners to keep them from being removed.
