How to Spot Damage to a Commercial Roof

If you own a commercial property, keeping your roof in good shape is crucial. A damaged roof can lead to expensive repairs and make your building look neglected. Here are some clear signs of commercial roof damage and how to protect your investment.

Signs of Roof Damage

1. Mold Growth

  • Happens due to water leaks from the roof or poor ventilation.
  • Prevent it by keeping your building dry and well-ventilated.
  • Use a bleach solution or trisodium phosphate to remove mildew.

2. Ponding Water

  • If water collects on your roof after rain, your drainage system isn’t working properly.
  • Pooling water can cause leaks and structural damage.
  • Hire the best roofing contractor to fix drainage issues before they worsen.

3. Cracks and Blisters

  • Cracks, blisters, or bubbles on your roof mean the material is weakening.
  • These issues reduce the roof’s lifespan and can lead to leaks.
  • Contact residential roofing contractors near me for an inspection.

4. Ceiling Stains and Water Damage

  • Water stains on ceilings mean your roof is leaking.
  • Mold or mildew on walls indicates moisture buildup.
  • A professional roofing inspection can pinpoint the leak source.

5. Missing or Damaged Flashing

  • Flashing seals roof cracks and prevents water from entering.
  • If it’s bent, cracked, or missing, your roof is vulnerable to leaks.
  • Get residential roofing contractors to repair or replace flashing immediately.

6. Rips or Tears in Roofing Material

  • Tears in roofing material expose your building to water damage.
  • Ignoring small rips can lead to costly structural problems.
  • Schedule a roof inspection to prevent further damage.

7. Missing or Warped Shingles

  • Missing shingles are a clear sign of roof wear and tear.
  • High winds and storms often cause shingles to loosen.
  • Replacing shingles is an affordable way to maintain your roof’s integrity.

8. Warping or Buckling

  • Flat roof warping is a major red flag.
  • Causes include natural aging or poor installation.
  • Work with the best roofing contractor to ensure proper installation.

9. Rusted or Clogged Gutters

  • Gutters direct water away from your building.
  • Rust or blockages prevent proper drainage, leading to leaks.
  • Clean gutters regularly to avoid water damage.

10. Exposed Nails

  • Exposed nails weaken the roof’s structure.
  • They can cause leaks and rust over time.
  • Use a nail finder to locate and fix exposed nails.

11. Missing Roof Aprons

  • Aprons help prevent water from seeping into the roof.
  • If any are missing, replace them immediately.
  • Proper aprons keep your roof watertight and secure.

12. Noisy Roof (Creaking or Squeaking Sounds)

  • Strange noises can indicate structural issues.
  • Don’t ignore cracking sounds in your roof.
  • A roofing expert can inspect for hidden damage.
  • Protect Your Roof and Save Money

Whatever the damage, taking action early saves money. Follow these steps to keep your commercial roof in top shape:

  • Schedule regular roof inspections.
  • Clear gutters and drains to prevent water buildup.
  • Fix small issues before they become big problems.

About The Author

Founder. Builder. No Plan B.

For ten years, Scott worked jobs that looked stable on the surface—finance, insurance, corporate roles—but always felt like they belonged to someone else’s vision. He wasn’t building anything of his own, and the day-to-day offered little more than repetition.

After a personal and financial low point—including a Chapter 7 bankruptcy—he found himself starting over with almost nothing. A friend gave him a shot in roofing sales. Two small jobs in, someone wrote his commission on a napkin at a diner table. The number was more than he’d made in weeks. That’s when he saw what this industry could offer—not just income, but real ownership over your success.

From there, everything changed.

Scott built this company to give others the same shot he got. He doesn’t look for perfect résumés—he looks for people with drive, character, and something to prove. His goal is simple: train in weeks what took him a decade to learn, and create a path to success that’s real, not theoretical.

Today, he leads one of the fastest-growing roofing and solar teams in Texas—but he’s still walking jobs, coaching reps, and checking in with homeowners. Because no matter how big the company gets, the mission stays the same: do the job right, take care of your people, and never forget where you started.
