Top 5 Mistakes in Commercial Roof Replacements and How to Avoid Them

5 Min Read

Does your roof need replacing?

It’s a scary situation. After all, you don’t want to get the wrong roof or have any other issues come up. Given the large financial investment involved, you want to make sure things go right the first time around.

Fortunately, you’re in the right place. Let’s take a look at some common mistakes to avoid when making mistakes in commercial roof replacements.

1. Not Having It Inspected Often

Failing to inspect a commercial roof replacement on a regular basis can lead to serious issues down the line. Not only can small issues turn into costly repairs if not caught quickly, but having an untrained eye inspect the roof can lead to mistakes in commercial roof replacement that can be hard to spot.

Anything from incorrect drainage systems to minor punctures, a few months or even a year later, can turn into major problems that end up costing thousands. Keeping a closed window on the progress of your commercial roof replacement by having it inspected often can save you money and headaches in the long run.

2. Incorrect Nailing

Incorrect nailing during a commercial roof replacement can be extremely detrimental to the structure and longevity of the roof. If nails are too short and not properly fixed into the trusses, for example, it can lead to roof failure, such as uplifting or leaking during severe weather events.

Short nail penetration will also create potential weaknesses in the roof deck and may allow moisture to enter. If nails are too long, they can cause the material to buckle around the nail, making it difficult to seal properly, leading to water infiltration and accelerated aging.

3. Not Having a Leak Barrier

When it comes to replacing a commercial roof, it is important to have a leak barrier. Without a leak barrier, it is almost guaranteed that the customer will experience water damage due to rainfall or other forces.

Having a qualified roofing contractor inspect the roof for any water damage as part of a proper installation is essential. Furthermore, a leak barrier should be inspected by a professional roofer yearly to ensure that it is still intact and properly functioning.

4. Having Inadequate Ventilation

When mistakes in commercial roof replacements are made improperly, they may be missing the vital step of ensuring adequate ventilation. When installing new commercial roofs that are not properly ventilated, the building can suffer from excess humidity and moisture.

This can lead to higher energy costs, mold growth, and accelerated roof deterioration. Additionally, poor ventilation can lead to decreased air quality in the building, causing occupants to experience a stuffy or uncomfortable environment.

5. Ignoring the Drip Edge

The drip edge is an essential component in stopping water from the roofing system from entering the building envelope. When the drip edge or flashing is not installed properly, water can easily get behind the roofing materials and cause water damage and costly repairs.

Furthermore, ignoring the drip edge gives water a path to run down the walls of the building. This can lead to rotting of the walls, mold growth, and further water damage, not to mention the potential health risks associated with mold exposure.
