How Do I Know If My Commercial Roof Needs Repair?

Owning or managing a commercial property in Flower Mound, TX comes with many responsibilities—and your roof is one of the most critical components of the building. Yet, it’s often overlooked until there’s a leak or major damage. So, how do you know when your commercial roof needs repair? The truth is, that catching issues early can save you thousands of dollars and prevent business disruptions.

In this blog, we’ll explore the most common signs that your commercial roof may need repair, the types of damage to look for, and why acting fast is the smartest move for your business.

Why Commercial Roof Repair Matters

Your roof protects everything underneath it—your inventory, equipment, employees, and customers. When the roof is compromised, it can lead to:

• Water damage
  
  
• Mold or mildew growth
  
  
• Structural deterioration
  
  
• Increased energy bills
  
  
• Lost productivity or downtime
  
  

That’s why knowing when to call in a professional for a commercial roof inspection or repair is so important.

Top Signs Your Commercial Roof Needs Repair

Let’s break down the red flags that suggest it’s time to have your roof professionally assessed.

1. Visible Leaks or Water Stains Inside the Building

This is the most obvious sign something is wrong. If you see water dripping during rain or stains on ceilings or walls, your roof’s membrane or seams may be compromised. Even small leaks can worsen over time and damage insulation, wiring, and drywall.

2. Blistering or Bubbling in the Roofing Membrane

On flat roofs like TPO, EPDM, or modified bitumen, blisters and bubbles in the membrane usually indicate trapped moisture or poor installation. These areas are prone to cracking and leaking if not repaired.

3. Ponding Water That Doesn’t Drain

If water pools on the roof for more than 48 hours after rain, it’s a serious concern. Ponding weakens the structure over time and can lead to roof collapse. Poor drainage might be due to clogged scuppers, sagging, or insulation failure.

4. Damaged Flashing or Seals

Flashing is the metal material used to seal edges, corners, and penetrations (like vents or skylights). If flashing is cracked, rusted, or pulling away, it allows water to sneak in.

5. Rising Energy Bills

Not all signs are visible. If your heating and cooling costs have spiked recently, it could be due to insulation or ventilation issues caused by roof damage. A poorly functioning roof can compromise your building’s energy efficiency.

6. Roof Age or Lack of Maintenance

Most commercial roofs last 20 to 40 years depending on the material and upkeep. If your roof hasn’t been inspected in years, it’s time. Preventative maintenance often uncovers issues before they become expensive repairs.

Common Causes of Commercial Roof Damage in Flower Mound, TX

Here in Flower Mound, commercial roofs face unique environmental challenges:

• Severe thunderstorms and hail (especially in spring and summer)
  
  
• High heat and UV exposure, which causes membrane shrinkage
  
  
• Wind damage can loosen panels or membrane seams
  
  
• Tree debris or clogged drainage systems that lead to ponding
  
  

It’s always a good idea to schedule a roof inspection after a major storm or before Texas' intense summer heat kicks in.

Types of Commercial Roofing Systems & Their Issues

Not all roofs are created equal. Here’s how different systems show damage:

• TPO & EPDM: Look for membrane punctures, seam separation, and wrinkles.
  
  
• Modified Bitumen: Cracks, splits, and granule loss are key indicators.
  
  
• Metal Roofs: Rust, corrosion, uplifted panels, and loose fasteners.
  
  
• Built-Up Roofs (BUR): Blistering, cracking, and gravel displacement.
  
  

A qualified contractor like Lancaster Roofing can determine the best repair strategy based on your roof type and the extent of the issue.

What Should You Do If You Suspect Roof Damage?

Here’s a quick action plan:

1. Document What You See

2. Call a Local Roofing Specialist
   Get a professional inspection from a company that understands Flower Mound's climate and roofing codes.
   
   
3. Don’t Delay Repairs
