How do you inspect and maintain your commercial roofing

Nov 1

Flat/low-slope roof cover

Flat and low-slope roof kinds can cause severe weathering that causes your roof membranes to crack. The long-term standing water may cause the growth of mold and plants. Check the roof's underside and drop ceiling for damage from water. This means that your roof's roof covering might be damaged. Other aspects to take into consideration include:

  • Be sure that the roof membrane isn't damaged.

Bitumen roofs modified and built-up should be examined for bubbles or blisters and fractures, as well as excessive wear around connections, tears, punctures and severe weathering that leads to the loss of gravel embedded or smooth protective coatings on the surface.

  • Single-ply: Check for tears, worn seams and seams that fail. Check for unusually loose membranes or blisters in adhesive- or glued down systems.
  • The acrylic coating might be removed by over-weathering or splitting, punctures or punctures in the sprayed polyurethane foam.
  • Metal panels must be checked for wear on rubber washers as well as loose screws. These could cause metal panels to rust over time. It is important to look for signs of rusting, as well for discolored or worn paint. This is an anti-rust coating. Also, be aware of scratches or divots.

Roof protecting a roof with a steep slope

Verify that the roof is not bowing , and is still maintaining its shape. Other factors to consider are:


  • Inspect asphalt shingles for cracks damaged or broken shingles.
  • In clay and concrete tiles, be on the lookout for cracked or missing tiles.
  • Inspect metal panels for worn washers and loose screws which are susceptible to deterioration with time. Look for evidence of rust along with discolored or worn-off paint, which works as an anti-rust coating. Also, look out for scratches and divots.


Drainage solutions for roofs

Remove any loose material from your roof like sticks, leaves and construction waste. Also, get rid of the dirt as well as other granules, which may be stuck in gutters or roof drains.

Check your gutters for obstructions that may be causing standing water. If there aren't any blockages but there's still standing water, you need to make sure the gutter slopes correctly to the downspout.

Check the perimeter flashing for any signs of damage. In high winds poor fitting or loose flashing can increase the chance of roof covering failure and water entry.

Equipment mounted on the roof

  • Examine the surface of metal panels, screws and flashings of metal on curbs to check for corrosion.
  • Check the connection of the equipment to the curb. If you see indications of leaks in the curb, check the connection between the equipment and the curb. You should inspect curbing for indications of decay, and replace it if you believe there's a water leak.
  • Take all wires and straps to make sure they're properly fastened; there should be no looseness. Refer to the manufacturer's instructions for further details.
  • Look for flashings in the vicinity of roof-mounted equipment curbs. This can lead to water penetration or structural damage.
  • Take away all debris from the area surrounding and under equipment mounted on roofs. It is possible for water to pond as a result of debris.
  • Make sure that fasteners have been secured on all service panels to avoid them being displaced.
