Warning signs

Is Your Commercial Roof Failing?

Visible Leaks or Water Stains

The most obvious sign, often appearing on ceilings, walls, or dripping onto equipment.

Pooling or Standing Water

Water remaining on your flat roof for more than 48 hours is a major sign of improper drainage.

Membrane Damage

Visible cracks, blisters, tears, or punctures in the roof's surface.

Compromised Flashing

Gaps, cracks, or wear around vents, skylights, or parapet walls.

Increased Energy Bills

A sudden increase in costs can indicate compromised insulation in a failing roofing system.

Rust or Corrosion

On metal commercial roofs, rust or extensive corrosion is a clear sign the system is failing.

Mould or Damp

Mould, mildew, or a damp smell inside your building can point to a hidden roof leak.

Commercial Roofing Emergencies
A roofing emergency on a commercial property can bring operations to a halt, putting your assets, inventory, and employees at risk. We understand every hour of downtime costs you money.

Choose wisely

The true cost of cheap work.

A commercial roof is a major investment. The consequences of bad workmanship go beyond leaks — they can lead to operational disruption and costly asset damage.

Improper Material Application

Using the wrong materials or failing to follow manufacturer instructions can void the warranty and lead to premature failure.

Poor Seam Welding

On single-ply membranes, weak or improper seam welds are a guaranteed point of failure and immediate leaks.

Incorrect Drainage

Failing to ensure proper slope and drainage leads to dangerous pooling water that can cause partial collapse.

Failure to Comply with Regulations

Unqualified contractors cut corners that leave your property non-compliant with building and safety codes.

No Structural Assessment

A cheap job might cover up existing structural damage, leading to catastrophic failure.

This depends on the terms of your lease. Many commercial leases include a 'repairing covenant' that makes the tenant responsible. Check your lease or ask your landlord.

EPDM and TPO single-ply membranes are the most popular for flat commercial roofs. The best choice depends on your building type, budget, and usage.
