Commercial roofing can have problems just as private homes do. Some of the most common problems that occur can range from a minor inconvenience and small repairs up to serious issues that require a complete replacement of the roof materials. In a number of situations, the structure under the roof may also need to be replaced, and repairs alone may not be sufficient.Commercial RoofingLeaks are one of the biggest issues with almost any type and shape of roof, but a leak is just a symptom of the underlying problem that needs to be taken care of. Before one or more leaks can be eliminated you will need to figure out why the water is getting in where it shouldn’t, and that can be a stressful situation that is not easy.

Although they seem uncomplicated, flat roofs require a high level of craft, particularly at the edges, where they join the masonry walls.

An experienced and professional roofing contractor can usually locate the source of the leak fairly quickly, and determine what is causing your specific situation and how to fix it without affecting the usual activities on the commercial property. The contractor should have plenty of past experience on your roof type to ensure the best results.

Commercial Roofing Can Experience Shrinkage

Shrinkage can occur with commercial roofing for many reasons when a single ply flat roof involves a waterproof membrane. Shrinkage causes the roof to pull away and can allow water in. The roof design, substrate deterioration, workmanship, or even materials that are poor quality or defective in some way can cause this problem.

Flat Roofs May Have Ponding in Spots

On flat roofs, ponding can occur and this can become a problem that gets worse over time. Ponding is the term used to describe water that pools and stays in one area of the roof. This can weaken the materials and cause other issues if it is not taken care of as soon as possible. Standing water on the roof allows moisture in and increases the weight involved.

A BUR may not have a sufficient slope towards a drain, or may have low spots that do not drain.

Blow Offs Are More Common Than You May Think

Blow offs can create issues with commercial roofing, and this is more common than you may think. High winds and severe weather can cause some of the roofing materials to come loose and leave gaps that allow moisture into the underlying components of the roof. The area affected needs to be repaired immediately to minimize any further damage.

If not adhered properly to the substrate, single-ply roofs are at risk for blow-off and billowing.

Poor Installation or Repairs

When you need commercial roofing installation or repairs then a professional roofing contractor should be consulted. This is true whether you have flat roofs or there is a pitch involved. Poor installation or poor quality repairs are common and this is something that the experts see on a regular basis. Make sure your roofing contractor is the right one for the job.

A Lack of Proper Maintenance

Maintenance is needed with commercial roofing, and if the roof is not properly maintained then it could start to weaken or become damaged over time in other ways. Always follow the recommended maintenance schedule, and address any issues as soon as they come up. This will help you avoid the most common issues and repair expenses.

Punctures or Blistering on a Roof Surface That is Flat

A lot of commercial roofing jobs involve flat roofs, and these can experience blistering and punctures that allow water into the sealed areas. The sun can cause blisters to appear on the surface of the roof material, especially in regions where the temperatures are high. Punctures can also occur with the roof membrane and create a gap that moisture can get through.

As they age, single-ply and built-up roof surfaces eventually exhibit signs of wear such as blistering, bubbling and cracking of the roof membrane, and separation of seams.
