As a commercial building owner or manager, you must pay close attention to the condition of your roof.

All it takes is one powerful storm to cause significant roof damage which can develop into further costly maintenance problems. Here’s a commercial roof inspection checklist for maintaining the longevity of your commercial roof.

1. Document Who Works on Your Roof

Keep a record of each specialist who goes on your roof and the time they worked. Explain why they went on your roof and identify the area in which they worked. This precise tracking will help you pinpoint specific issues regarding specific places on your roof.

2. Evaluate Condition of Roof Components

Use a scoring system to rate the condition of the material on your roof. Differentiate between items in good condition, those which need monitoring, and components requiring immediate action.

3. Take Photos of Damage

You’ll need to take high-resolution photos of your roof damage for various reasons, such as providing evidence to your insurance company. Taking before and after photos will help you determine how well the problem was fixed if roofing components need to be replaced.

4. Keep a Toolkit Available

A toolkit should include basics like a pen, notepad, tape measure, and flashlight to help you assess items being inspected. There are also plenty of apps for your smartphone which can give you various measurements to help with the inspection.

5. Consider Your Roof Type for Taking Action

Different procedures are taken for flat roofs versus sloped roofs. For flat roofing, look for ponding, holes, punctures or blisters in the material. Anything pulling away from the roof should be a concern. Sloped roofs can be dangerous to walk on; the surface can be slippery because of water, moss, mold, or mildew. Look for the following problems regarding shingles.

  • missing, curled, damaged shingles
  • Shingles with missing granules
  • color fading; corroded
  • bent or missing metal
  • chipped, broken, or cracked tile/slate

6. What You See from the Interior

A thorough inspection includes checking your interior. If you see signs of mold or dark spots check to see if they are peeling. If you feel damp areas around vents and chimneys you may need to stop the moisture right away.

By checking your ceiling for moisture, it’s possible to prevent mold, mildew, and further leaks from spreading. You should check your walls for leaks to make sure your insulation provides adequate protection. Proper ventilation is also key to a safe indoor environment.

7. Eliminate Safety Hazards

Remember that a leaky roof could mean water is getting into the building where it should be dry. Be aware electrical components should always avoid contact with water, which can generate an electric charge and lead to shock.

Make sure water is not getting into your fuse box or other electrical systems. Check the rafters and sheathing for cracks, as well as sagging decking. Note any type of light shining through your roof or opening which allows water to get into the structure.

8. Water or Air Leaks

Sometimes even small leaks can grow into bigger problems. Make sure your inspection is thorough enough to cover all possible leaks. Undetected small leaks are a top cause of maintenance issues.

Leaks can occur in every place imaginable, including chimneys, vents, and skylights. Roof-mounted HVAC systems should also be inspected for leaks and other damage.

9. Damage and Debris

From the outside look for obvious signs of debris and roof damage. Check for blocked or broken gutters and downspouts which may interfere with water flowing away from the building. Be on the lookout for corrosion, rust, rotting, moss or fungal growth, as well as degraded flashings, chimneys, vents, fascia, drip edges, and decking.

Noting other damage and debris on nearby buildings in the area will help you plan better for the next big storm. Check to see if similar damage has occurred throughout the area.

10. If Action Is Needed

After conducting an inspection, decide if the damage is substantial enough to call in a professional commercial roofer in Tulsa to perform a more intense inspection. Determine which tasks your maintenance crew can handle themselves. It’s always advantageous to hire an expert roof inspector following a severe storm causing trees and telephone poles to collapse.

Certain actions should be left to certified, licensed roofing experts who make safety and high-quality top priorities. Using the right tools and knowledge makes a big difference.Working with a seasoned roofer can help ease the load from a commercial roofing inspection and save money in the long run.
