When Should I Have My Commercial Roof Inspected?

Although the thought of inspecting your commercial roof regularly may seem like a bother, it becomes worthwhile when you consider the benefits you will get from a strong, reliable, and long-lasting roof. Replacing a roof now and then is a costly undertaking that can easily be avoided by ensuring that your roof is always in perfect condition.

The only way you can achieve this is through regular roof inspection. A roof inspection involves several things, including checking for damaged insulation, ventilation, mold, leaks, and improper flashing. Continue reading to know when you should have your commercial roof inspected.

How Often Should Your Commercial Roof Be Inspected?

Many professional roofers recommend that you have your commercial roof inspected at least twice a year, especially if it is a large, flat roof. However, there are common signs that you should look out for to know if your commercial roof needs inspection.


As your roof continues to deteriorate, it will sink or sag around the damaged areas. However, you shouldn’t wait until your roof starts to sag to have it inspected because not all damaged roofs will sag. Therefore, you should watch out for unevenness in your roof.


If you notice signs of bubbling or blistering in your commercial roof, it means that the roofing materials used are not strong, were not correctly installed, or that the roof’s inner components have sucked in moisture. These are signs of more serious trouble on the way. So, have your roof inspected by a professional for a more comprehensive assessment.

Damaged or Missing Pieces

A commercial roof with damaged or missing shingles and other components requires immediate professional attention. These are signs of a weak roof that needs repair or replacement. Only after a thorough inspection will you be able to know whether to repair or replace the roof.

Interior Moisture

Any amount of moisture accumulation around your roof should get you worried. Even if the wetness appears on walls, ceilings, or siding, it could point to a leaky roof. Also, if you notice a damp odor reminiscent of an inadequately lit or ventilated basement, you need to have your roof inspected by a professional for advice.

Increased Energy Costs

If your roof is damaged, there will be an excessive concentration of air in your house. This can drastically increase your energy costs, especially in extreme hot and cold seasons, because your heating and cooling systems will be forced to overwork.

Ensure your commercial roof is inspected by a qualified roof inspector who understands different types of roofs and roofing materials.
