Metal roofs are known for their durability, energy efficiency, and longevity, often lasting 40 to 70 years when properly maintained. However, metal roofs are not immune to damage. Metal roof leaks typically arise from aging materials, poor installation, or environmental exposure. Below are common causes metal roofs may leak and their solutions:

1. Improper Fastener Installation

Cause: Overdriven, underdriven, or misaligned screws allow water to seep through.
Solution: Inspect and replace fasteners with the correct torque. Use neoprene washers for sealing.

2. Failed Seams or Laps

Cause: Expansion and contraction from temperature changes loosen panel seams over time.
Solution: Apply seam sealant or install standing seam clamps. Regular resealing is key.

3. Missing or Damaged Sealant

Cause: UV exposure or age breaks down sealant around joints and penetrations.
Solution: Remove deteriorated sealant and apply high-performance, UV-resistant roof sealant.

4. Rust and Corrosion

Cause: Prolonged exposure to moisture leads to metal oxidation.
Solution: Remove rust with wire brushing and treat with corrosion-resistant coating or replace sections.

5. Clogged or Damaged Gutters

6. Improper Flashing

Cause: Incorrect or failed flashing around chimneys, vents, and edges causes entry points for water.
Solution: Replace faulty flashing with correctly sized, watertight alternatives.

7. Roof Penetrations (Vents, HVAC, Skylights)

Cause: Water seeps in where the roof is punctured for utilities or structures.
Solution: Reseal or reflash penetrations using compatible materials and secure closures.

Flat Roof Penetrations – What You Need to Know

Are your commercial flat roof penetrations responsible for costly and inconvenient leaks? Knowing what penetrations are for and how they affect your roofing system helps you keep them from causing leaks and severe structural damage to your property.

New Image Roofing Atlanta gathered information about commercial flat roof penetration purposes, installation, maintenance, and inspection.

What Are Flat Roof Penetrations?

sealing penetrations on flat membrane roofing systems

Flat roof penetrations are any objects or systems that pass through the surface of a roof. These are necessary for the functionality of a building and include systems related to plumbing, HVAC, electricity, and more. Because they interrupt the continuous waterproof membrane of the roof, they must be carefully installed and maintained to prevent leaks and structural damage.

Common Flat Roof Penetrations

hatch penetrations on flat membrane roofing systems

Roof penetrations are essential features that allow necessary building systems to pass through the roof. However, if not properly maintained, each penetration represents a potential water entry point. Commercial flat (low-slope) roofing systems often have multiple penetrations, like:

  • Plumbing vents – Ventilates plumbing systems and prevent sewer gas from entering the building.
  • HVAC units – Rooftop air conditioning units and ductwork often require significant penetrations.
  • Electrical conduits – Provide pathways for power and communication cables.
  • Drains and scuppers – Allow water to exit the roof and prevent ponding.
  • Gas lines – For heating systems or industrial appliances.
  • Roof hatches – Provide access to the roof.
  • Skylights or solar panels – Require penetrations for installation and wiring.
  • Antennae and satellite dishes – Used for telecommunications and broadcasting.
  • Exhaust fans and flues – Removes stale air, smoke, or gases from the building.
  • Lightning protection systems – Grounding systems that require roof access.

How Roof Penetrations Are Flashed

flashing penetrations on flat membrane roofing systems

Roofers use flashing to ensure roof penetrations are watertight. Flashing involves sealing the area around a penetration to prevent water intrusion.

Flashing Techniques Include:

  • Boot flashing – A pre-formed collar, usually made of rubber or metal, that fits around the penetration and is sealed to the membrane.
  • Pitch pans – Small metal containers filled with a sealant material used around irregularly shaped or grouped penetrations.
  • Pre-manufactured flashing kits – Specifically designed for certain types of equipment or systems.
  • Sealant and membrane integration – Roofers may use a combination of liquid sealants and roofing membrane to form a continuous seal around a penetration.

Each flashing method must be compatible with the roofing system (e.g., TPO, PVC, EPDM, BUR) and properly maintained to remain effective.

Preventing Leaks with Roof Maintenance

Penetrations are one of the leading causes of leaks in commercial flat roofs. Regular inspections and proactive maintenance can prevent costly damage and extend the lifespan of the entire roof system.

New Image Roofing Atlanta offers commercial roof maintenance programs designed to:

  • Identify early signs of wear or damage around penetrations

Visual Inspection

inspecting penetrations on flat membrane roofing systems

  • Check for visible cracks or gaps in flashing or sealant
  • Look for standing water around penetrations
  • Inspect for rust or corrosion on metal flashing
  • Examine boots or collars for signs of cracking or UV damage
  • Identify any signs of movement or detachment from the roof

Physical Testing

  • Gently tug on conduits, pipes, or boots to check for looseness
  • Press on flashing edges to assess adhesion to the membrane
  • Tap on pitch pans to determine if the sealant is brittle or cracked

Documentation

  • Photograph all penetrations during inspection
  • Note the condition and flashing type used
  • Record previous repairs or recurring issues

Maintenance Recommendations

  • Re-seal or replace compromised flashing
  • Remove debris obstructing drainage
  • Schedule immediate repairs for high-risk areas
  • Apply protective coatings if UV degradation is present

Commercial Flat Roof Damage – Common Causes

Atlanta Georgia commercial flat roof repair standing water

Commercial flat roofing systems are durable but require regular maintenance and occasional repairs to maintain their integrity. Flat roofs are exposed to harsh weather conditions, standing water, and foot traffic, all contributing to damage. Several factors contribute to flat roof deterioration, leading to necessary repairs, including:

  • Weather Damage – High winds, heavy rain, hail, and extreme temperatures can cause cracks, leaks, and membrane wear.
  • Standing Water – Poor drainage can lead to ponding water, weakening roofing materials and causing leaks.
  • Foot Traffic – Frequent rooftop activity from maintenance crews can create punctures or tears in the roofing system. Read more about roofs with excessive foot traffic HERE.
