What is Ponding Water and How Will It Affect Your Flat Roof?

Commercial Roofing Ponding Water Issues

Water is essential for life and there would be no construction without it, but when building components are constantly exposed to the element, they get damaged quicker that you can imagine. The Commercial roofing CT area are designed and built to protect buildings against the elements, including water in any form, but they can fulfil their role only if they are allowed sufficient time to dry, that’s why any accumulation of water on the roof surface is extremely harmful for the roof.

Ponding water – the term used for small pools of water that appear because the roof has lost its flatness – can be caused by many different roof faults:

  • A fault of the drainage system – clogged gutters and downspouts prevent proper water elimination and cause water ponding;
  • Incorrect pitching – even flat roofs need to have a little slope to allow water to roll down;
  • Too much material on the roof edges – another issue that prevents proper drainage.

The effects of prolonged water pooling are a general weakening of the roof that manifests in the form of the increased frequency of leaks, roof sagging, the appearance of moss, algae, mold and mildew on the roof, in the attic and in the building. When noticed in time, water ponding can be corrected, but water is a powerful enemy that can destroy the entire roof if the problem is addressed in a timely manner.

Components of a Commercial Roofing System

Commercial Roofing Structure

Most flat or low-sloping commercial roofs consist of three principle components: one or more weatherproofing layers on the top to prevent water from penetrating the deeper layers of the roof and usually fitted with an extra layer of surfacing to protect those deeper layers from the sun and the wind and a reinforcement layer to add strength and stability. Depending on the type of the commercial roof, the components are made from different material:

  • Built-up roofs – this type of roofing consists of alternated layers of sheets made from tar or other suitable material and gravel or liquid surfacing;
  • Modified bitumen roofs – these roofs use sheets of modified bitumen adhered with a roofing torch. Modified bitumen is more resistant and more durable than conventional bitumen;
  • Foam roofing – these roofs consist of a decking on which a suitably thick layer of polyurethane foam is applied from a large spraying gun and then granules and various top coatings are added for weatherproofing and enhanced protection against impact, UV radiation, wind and water;
  • EPDM roofs – also known as rubber roofs, these systems use sheets made from special sheets of rubber material fastened together with seam tape and fixed with a bonding adhesive to the deck.

Spring Commercial Roof Maintenance

Time For Spring Maintenance Projects

The cold season is a challenge for every roof, which is why the beginning of spring is the ideal time for scheduling maintenance. On this occasion, the entire surface of the roof must be checked thoroughly, and potential problems that occurred during the cold months have to be fixed.

Who must do the maintenance of a commercial roof?

Roof inspections performed by commercial roofing Connecticut specialists trained and experienced in flat roofing. They have adequate equipment to detect problems, they provide professional advice as well as long term maintenance plans.

Special equipment such as infrared scanners must be operated by personnel certified in thermography. Roof repairs must be carried out by specialist builders certified by manufacturers.

What is included in the spring commercial roof maintenance?

  • Cleaning the roof and its drainage elements from debris, soil, vegetation etc.
  • Inspecting the roof`s membrane for early detection of possible problems (visual inspection along with infrared scanning provides a clear picture and precise diagnosis of the entire roof system)
  • Correct and rapid repairs of the roof, performed by roofers specialized in flat roofs and certified my manufacturers

As a precautionary method, it is recommended that you periodically resume the maintenance program and limit the traffic on the roof to authorized personnel only. The waterproofing efficiency of a flat roof should be impeccable, because water infiltration can cause great damage.
