As local roofing and cladding specialists, we must stress that your roof needs attention before problems appear. If you’re wondering how to repair a commercial roof when you’re patching punctures and fighting flashing leaks, the likelihood is you’ve acted too late.
Far too many commercial landlords take a ‘fit and forget’ mindset, only turning their attention upwards when a water stain appears on a ceiling tile. By then, the damage is done, and the costs are mounting.
Commercial roofing is the primary shield between your tenants and the elements; it protects operations, inventory, and, most importantly, people. Taking a proactive approach from the get-go is the only way to stop problems before they happen.
Take a planned approach to maintenance
The secret to a long-lasting commercial roof is preventative, planned maintenance.
You don’t want to be responding to leaks as and when. With a structured schedule already in place, your strategy shifts from reacting to actively managing the health of your building. You must treat roof care as an ongoing, budgetable requirement.
When maintenance comes as an unexpected capital shock, things can quickly escalate. But prolonging the life cycle of your roofing system can save you up to 50% over the life of a typical 30-year roof compared to premature replacement.
Planned preventative maintenance (PPM) schedules map out exactly what needs doing over a multi-year period, and during this time, it’s essential to keep detailed logs of all checks and repairs. Documenting this history makes budgeting easier.
Recognise warning signs through regular inspection
You can’t fix what you don’t know is broken, and while some problems are immediately visible, others require an experienced eye. Professional assessments should be carried out at least twice a year.
These are typically arranged in the spring to assess winter freeze-thaw damage and in the autumn to clear debris and prepare for harsher weather. You should also arrange ad-hoc checks after severe storms.
Penetration points around HVAC units, skylights, vents, and chimneys are notorious for developing weak spots where waterproof seals degrade. Inspectors will usually be looking for splits, punctures, cracks, lifting edges and areas where the covering appears distorted.
You can’t always assume that water has entered directly above the place where it appears. For example, it can travel through the roof construction or enter through adjoining cladding. Often, you need a professional who can trace the route and address the underlying cause.
Keep the surface and drainage system clear
If rainwater can’t escape, it will pool – that’s why water is the greatest enemy of a commercial roof. Debris accumulation from fallen leaves, branches, silt, and dirt is a major cause of roof deterioration because it traps moisture directly against the material.
Without a clear drainage system, persistent ponding imposes immense structural loads on the building and can even accelerate the breakdown of waterproofing membranes.
Water should drain properly within 48 hours of rainfall, and it’s equally important to address organic growth.
Protect the roof from avoidable damage
Weather isn’t the only cause of deterioration. In fact, many causes of commercial roof damage are entirely avoidable with careful management.
Foot traffic, for example – your roof isn’t a regular floor, and without proper precautions, maintenance personnel servicing HVAC systems can inadvertently cause structural depression.
After work on air-conditioning units or solar panels is complete, check for damage around penetrations. Make sure load-spreading measures, like scaffold boards or walkway pads, are used, especially at access points and ridges.
Repair problems as soon as they’re identified
When an inspection reveals a fault, no matter how insignificant it may seem, act immediately – a small defect rarely improves by itself.
Delaying minor repairs is a false economy that results in costs multiplying tenfold when moisture finally breaches the insulation layer. In the same way, avoid relying indefinitely on temporary patches.
Reactive maintenance should include the immediate replacement of damaged sheets, re-securing loose fixings, and repairing flashing to re-establish a watertight seal around roof penetrations.
