The Five Most Expensive Roof Problems That Start Really Small

This blog was written by Craig Rainey, second-generation owner and Executive VP of Supreme Roofing. 

At Supreme Roofing, we help property managers protect their buildings with clear plans that reduce risk and control spending. 

Hello, my name is Craig Rainey. 

I’m the second-generation owner and current Executive VP of Supreme Roofing. I’ve spent my entire life working on commercial roofs across Texas and beyond. 

Over the years, one truth has been proven again and again: most roof emergencies start small.

Catching early warning signs is the key to keeping water out, protecting interiors, and avoiding the surprises that can derail a maintenance budget. 

As we head into a new year, budgeting is top of mind for every property manager. 

Roofs can be one of the most unpredictable line items, but they don’t have to be. 

By spotting small problems before they escalate, you can plan repairs on your terms instead of reacting to emergencies. 

Below are five common issues that start small but often lead to big invoices if left unchecked, you won’t want to miss these! 

Problem 1: Clogged Drains and Ponding Water

Water that lingers on a roof doesn’t just look bad — it shortens membrane life, adds weight to the structure, and finds every crack or seam. 

The most expensive problems start with clogged drains and ponding water.

• Why it gets expensive: standing water breaks down membranes, finds seams and cracks, and adds structural load.
  
  
• Early signs: slow drains, debris circles, algae rings, or soft insulation near low points.
  
  
• Quick checks: clear debris, confirm strainers are in place, and verify positive slope around drains and scuppers.
  
  
• What to document: recurring ponding areas, depth of water after 48 hours, and any sections that consistently back up.
  
  
• When to act: if water remains for more than 48 hours or drains consistently back up during storms.
  
  

Problem 2: Failed Flashings and Penetrations

Most leaks begin at the details, not the field of the roof. 

Flashings and penetrations around pipes, RTUs(Rooftop Units), and curbs take constant stress, and even a small split can become a major leak.

• Why it gets expensive: details are the first point of failure, and water spreads quickly from these areas.
  
  
• Early signs: hairline splits, loose termination bars, cracked caulk, UV cracking, or pitch pans pulling loose.
  
  
• Quick checks: tug test at pipes and RTUs, inspect corners, and confirm termination heights against manufacturer guidance.
  
  
• What to document: penetration type, condition, location, and immediate risk level.
  
  
• When to act: any visible gap, displaced flashing, or cracked sealant near equipment requires immediate attention.
  
  

Problem 3: Open Seams and Laps on Single-Ply

Single-ply seams are vulnerable to movement, wind uplift, and temperature swings. 

What begins as a tiny fishmouth or curled edge can quickly open into a leak path.

• Why it gets expensive: small openings widen under stress, saturating insulation and damaging interiors.
  
  
• Early signs: fishmouths, curled edges, loose welds at corners, or visible membrane shrinkage.
  
  
• Quick checks: probe suspect seams, verify weld continuity, and look for dust lines that mark airflow through openings.
  
  
• What to document: seam length affected, section location, and likely causes such as traffic or thermal stress.
  
  
• When to act: if a seam catches a probe or shows daylight, repairs are urgent.
  
  

Problem 4: Minor Punctures and Mechanical Damage

Not all problems come from the weather, many are caused by people. 

Foot traffic, dropped tools, or loose fasteners can create punctures that look small but lead to expensive damage.

• Why it gets expensive: punctures let water spread laterally, wetting insulation and driving up energy costs.
  
  
• Early signs: cuts near conduit, screws backing out, dropped tool marks, or tracked gravel on single-ply surfaces.
  
  
• Quick checks: inspect ladder landings, service paths, and high-traffic areas under mechanical trades.
  
  
• What to document: puncture size, possible source, and nearby moisture indicators.
  
  
• When to act: immediately, especially if punctures are near drains, seams, or penetrations.
  
  

Problem 5: High-Traffic Areas and Wear Paths

Commercial roofs are working surfaces, and constant foot traffic leaves a mark. Over time, wear paths crush insulation and scuff membranes until reinforcement is exposed.

• Why it gets expensive: repeated traffic creates micro-tears that develop into chronic leaks.
  
  
• Early signs: scuffed surfaces, compressed feel underfoot, exposed reinforcement, or loose and missing walk pads.
  
  
• Quick checks: map the service routes used most often, check around ladders, RTUs, and panels, and confirm walk pads are intact where trades travel.
  
  
• What to document: traffic locations, square footage affected, and details nearby that may be at risk.
  
  
• When to act: add or replace walk pads, reroute paths if possible, and repair scuffs before water intrusion begins.

SUPREME TIP: 

If you ever face an unexpected roofing emergency, our SWAT (Severe Weather Action Team) is on call 24/7, 365 days a year to respond and keep your property protected.

Prevent Roof Emergencies

Roof emergencies rarely appear overnight — they build slowly, starting with issues that seem minor until they become costly. 

That’s why we created the Roof Health & Budget Planning Report. After a short inspection, you’ll receive a clear, boardroom-ready document outlining your roof’s condition rating, near-term priorities, and realistic budget ranges. 

It’s designed to give property managers a tool they can take straight to ownership or accounting to defend budget requests and plan capital projects with confidence.
