5 Signs That Your Commercial Roof Is in Need of Renovation

Commercial roofing is more durable and long-lasting than residential roofing, but that does not make them free from harm. While repairs are the most common type of commercial roofing maintenance, some circumstances may demand a complete roof renovation.

Although a roof may seem in good condition, there are many signs that a roof may have already reached its lifespan. This is why it is essential to spot early signs of a commercial roof that needs a make-over or a complete change.

You may think that renovating your roof can be expensive, but a situation that could have been avoided by proper maintenance can cost you much more in repairs or even a complete roof replacement.

Here are five signs that your commercial roof needs renovation:

1. Leaking

Any leak should be fixed immediately, regardless of the size. Commercial roofs are designed to withstand the elements and last for years. However, that does not mean that a small crack can’t cause water damage and ruin the roof’s integrity.

Leaks can come from an issue with the roof itself or the shingles, which are the most common type of material roofs are made of. Thankfully, damage shingles can be replaced or recoat the commercial roof with a special coating on top of the shingles.

2. Curling or Warping

Curling can be caused by moisture and improper ventilation, and it can also be a sign of a roof that is not insulated well enough.

Warping, on the other hand, indicates improper installation. When a roof is installed incorrectly, it is not adequately supported and will warp under the added stress of weather.

3. Corrosion

Commercial roofs are exposed to many different types of corrosive elements, including water, ice, dirt, and chemicals. Signs of corrosion include rust-colored stains, flaking paint, and a general loss of color.

Corrosion has the potential to become severe and damage or destroy a roof. This may lead to leaks, which can harm the structure of the top and the building.

4. Sunken Ceiling Tiles

Walking on a commercial roof makes it possible to determine if it has started to sink. Leaks can cause hollow tiles, and the tiles will act like sponges and soak up water.

The weight of the water can cause the tiles to slip down and cause a permanent indentation on the roof. Sunken tiles can be dangerous because they can lead to other leaks and force the rofo to collapse entirely. This is sunken tiles can be an alarming sign that your commercial roof needs renovation.

5. Cracking

If your commercial roof has started to crack, it is probably past due for a replacement. Cracks can lead to warping and corrosion over time and a high risk of leaking. It is highly recommended to have it inspected at least once a year.


Several factors determine the longevity of a commercial roof. The size of the top and its location are the two most significant factors. A small, flat roof exposed to the elements is more vulnerable than a more extensive, pitched roof.

A commercial roof will need to be repaired, recoated, or replaced in its lifetime. If you notice any warning signs, such as leaking, corrosion, or sagging roof tiles, contact a commercial roofing professional as soon as possible.
