A commercial roof is a crucial investment for any business, protecting the property, equipment, and operations beneath it. However, due to their scale and exposure, commercial roofs are vulnerable to specific issues that can cause major disruption if left unaddressed. At Newark on Trent Roofing Repairs, we’ve supported many businesses across Newark on Trent, Nottingham in identifying and resolving roofing problems before they escalate. Here, we explore the most common commercial roofing issues and how to tackle them effectively.

Flat Roof Drainage Problems

The Problem:

Many commercial properties in Newark on Trent are built with flat roofs, which can be prone to poor drainage. Without a sufficient slope, water can pool on the surface, leading to:

  • Structural strain
  • Membrane breakdown
  • Moss and algae growth
  • Roof leaks

The Solution:

  • Install or maintain appropriate drainage outlets
  • Ensure regular roof inspections, especially after heavy rainfall
  • Apply a liquid roof coating to enhance waterproofing and improve drainage performance

Damaged or Aged Roof Membranes

The Problem:

Over time, roofing membranes such as EPDM, TPO, or felt can degrade due to exposure to UV rays, extreme temperatures, and general wear. Common signs include:

  • Cracks or blisters on the surface
  • Seam separation
  • Reduced flexibility in colder conditions

The Solution:

  • Carry out a professional roof inspection to assess the condition of the membrane
  • Repair or reseal damaged sections where possible
  • In severe cases, consider overlaying with a modern membrane or liquid roof covering to restore waterproofing

Roof Leaks and Water Ingress

The Problem:

Leaks are one of the most disruptive issues for any commercial building. These may originate from:

  • Poor flashing around vents and HVAC systems
  • Cracked or punctured membrane
  • Blocked drainage causing overflow

The Solution:

  • Identify the leak source with a comprehensive roof inspection
  • Replace or reseal affected areas, particularly around penetrations
  • Implement a proactive maintenance plan to catch early signs of wear

Poor Installation or Workmanship

The Problem:

A roof is only as good as its installation. Unfortunately, rushed or unskilled workmanship can lead to:

  • Loose or lifting edges
  • Poorly sealed joints
  • Unreliable insulation

The Solution:

  • Hire trusted and experienced roofing professionals for all commercial work
  • At Newark on Trent Roofing Repairs, we only use fully trained teams with commercial roofing expertise
  • Consider a roof condition report if you’ve inherited a property with unknown roofing history

Thermal Movement and Expansion

The Problem:

Commercial roofs, especially those made from metal, expand and contract with temperature fluctuations. Over time, this can cause:

  • Joint and seam stress
  • Fastener loosening
  • Material fatigue

The Solution:

  • Use flexible materials that accommodate movement
  • Incorporate proper expansion joints during installation
  • Regularly inspect joints and fastenings for early signs of stress

Debris and Vegetation Buildup

The Problem:

Roofs located near trees or industrial zones often collect leaves, dirt, and debris. If left unattended, this can block drainage and accelerate membrane wear.

The Solution:

  • Schedule seasonal roof cleaning, especially in autumn and spring
  • Install gutter guards and debris traps
  • Include debris clearance in your roof maintenance plan
