The sun is shining and the birds are chirping – it must be Springtime! And with Spring comes one of our busiest times of the year: Commercial Roof Inspections Season.

We see many different things on roofs after the snow and ice have thawed. Some require immediate attention. Some of them are, well, rather interesting.

In this blog post, we’ll discuss some of the things that our roof inspectors find during their inspections and which ones need are a cause for concern.

Why is Springtime such a good time for commercial roof inspections?

There are a few reasons why Spring is an excellent time for commercial roof inspections. For one, the weather is usually milder than during the Summer months. Spring is also a good time for commercial roof inspections as it’s when many problems tend to first appear.

During the winter, snow and ice can not only cause roof damage but can also hide certain damage and defects in the roofing material. Once melted, the damage becomes exposed. This can result in leaks that cause costly damage to your building and its contents. If you wait until the Summer to have your roof inspected, you may not be able to catch all the problems that need to be fixed before the rainy season.

What sorts of things do our roofers find when performing Spring commercial roof inspections?


A common problem that our roof inspectors find is worn-out or weakened roofing material. Roofing membranes, seals, and flashings wear out over time and, if not repaired or replaced promptly, can lead to more serious problems down the road. Winter is especially hard on flat commercial roofs, and this is the time to find out how well they survived.


Debris and leaves can often build up on the roof over time, leading to drainage problems. Springtime often reveals areas of your roof covered in wet leaves leftover from the previous fall. If they are blocking any part of the drainage system and water isn’t able to drain correctly, it can cause damage to the underlying structure and create a breeding ground for mosquitoes and other pests.


Water infiltration around vents or other roof penetrations is another common problem our inspectors discover during Spring inspections. As discussed in previous blogs, this can be caused by many things. There may already be signs of leaks inside the building. These issues require immediate repair before Spring and Summer’s heavy rains start.


Leaks are one of the main issues roof inspectors are looking for during their inspections. They often find leaks that may have been going on for months or even years without being noticed. This can be a huge concern, as leaks can cause severe damage to your building’s interior.


Pooling water is another concern that our roofers will frequently encounter during their springtime inspections. Pooling water can be a sign of a leaky roof, and it can also lead to the growth of mold and other pests. If you see pooling water on your roof, make sure to have it fixed right away.


When roof inspectors find signs of water damage inside the building, it’s always a sign that there is trouble. Water damage can cause extensive damage to the inside of your business, so it’s important to get it fixed as soon as possible. Insulation, drywall, and ceiling tiles tend to hold water, masking minor roof leaks, so it may not be evident in a casual walk-through.


Moss or algae growth is another problem that our roofers often find during their inspections. Moss and algae typically occur on the roof, not in the building’s interior. This can be a sign that there is something wrong with your roof’s drainage system preventing water from exiting the roof.


Mold and mildew are other common problems that our roofers discover during Spring commercial roof inspections. Mold can grow in any environment with high moisture levels, and it can be harmful to your health. Both can be hidden in interior building materials or along exterior walls that have absorbed water from minor leaks. And as we’ve often said before, small leaks eventually turn into big leaks.

Damp, dark areas are also a breeding ground for fungus and can appear as mushrooms or shelf-like growths. They can be a sign of a roof leak or a foundation leak caused by seepage from poor drainage.


Another issue that our roofers often find during Spring inspections is signs of insects and animals. Both can cause serious damage to the roofing material, so it’s essential to get them removed as soon as possible. Rodents can be especially destructive as they look for ways to get inside your warm building during the winter months. If they can’t find an entry point, they’ll make their own, making a perfect way for future rainwater to get inside your building.


You might be surprised what sorts of things we find on our client’s roofs. Magazines, orthodontic retainers, bicycles, car tires, bags of garbage, iPods, unmentionables – we’ve seen it all! If your tenants or employees have access to your roof, they may be accessing it more than you realize. But as long as we’re up on your roof inspecting it, we’ll check to see if there have been any dance parties that may have caused damage. Whose mirror ball is this?
