A commercial roof does not usually fail overnight. Most damage builds up over months or years, and by the time water appears inside the building the underlying cause has often been at work for some time. Knowing what to look for means you can act before the damage spreads to insulation, timbers, steelwork or stock.
The most telling early warning sign on a flat roof is pooling water. Flat roofs are designed with a slight fall so that rainwater drains away, but when that fall is lost - because the deck has deflected, or the outlet has blocked - standing water accelerates the breakdown of whatever membrane sits on top. On a felt roof, prolonged ponding softens and eventually splits the felt. On a single-ply membrane, it puts sustained pressure on the laps and seams.
Pitched roofs on farm buildings, workshops and retail premises give their own set of signals. Slipped or broken slates and tiles are obvious from ground level, but the less visible problems are often more serious. Corroded or loose ridge and hip mortar lets water run into the roof void without appearing as an obvious gap. Failing lead or aluminium flashings at chimneys, parapet walls and abutments are a common starting point for leaks on older commercial buildings.
On agricultural and industrial units with profiled metal or fibre-cement sheet roofing, look out for holes around fixing screws - the washers and seals on self-drilling fixings degrade over time, especially on south-facing slopes exposed to UV. Missing or cracked rooflights are another regular source of ingress on this type of building.
Age is the single biggest factor. Standard three-layer felt systems on commercial flat roofs typically last 15-20 years before the surface becomes brittle and prone to cracking. Single-ply membranes have a longer service life when properly installed, but no flat roof lasts indefinitely without maintenance.
Thermal movement is responsible for a large share of seam and lap failures. Commercial roofs cover large areas, and the membrane expands and contracts significantly between winter cold and summer heat. Every movement cycle puts stress on the joints. Roofs with poor or missing expansion provision fail faster at these points.
Foot traffic is underestimated as a cause of damage. Maintenance engineers accessing plant, HVAC units or rooflights walk across the membrane repeatedly, often without protection boards. Concentrated point loads crack felt and puncture single-ply material. Any roof that is accessed regularly should have proper walkway protection laid.
Blocked drainage is both a warning sign and a cause of further damage. A blocked outlet or downpipe turns a flat roof into a temporary pond. Even a shallow layer of standing water adds significant weight and keeps the membrane saturated. On a roof that is already ageing, that is enough to push water through cracks that were previously only surface-level.
If you can see any of the warning signs above, the sensible next step is to get someone up on the roof for a proper look. A visual inspection from ground level will miss most of the detail that matters - blistering, seam separation and early ponding are only visible from the roof surface itself.
Agricultural buildings and commercial units develop roofing problems for different reasons, and what the right repair involves depends on the existing materials, the extent of the damage and whether the deck beneath is sound.
A patch repair is sensible where the underlying deck is solid and the damage is genuinely isolated - a small split near a drainage outlet, for example, or a failed flashing on an otherwise sound pitched roof. It becomes poor value when the membrane itself is at the end of its life and further failures will follow within months. Honest advice at the inspection stage should tell you which situation you are in, so you can make the right decision for your business rather than spending on repairs that only delay a replacement.
Mildenhall Roofers covers Tuddenham and the wider area including West Row, Mildenhall, Lackford, Kentford, Elveden and Holywell Row. If you have noticed any of the warning signs described above - or if you simply cannot remember when the roof was last inspected - call us to arrange a roof survey so you know exactly what you are dealing with.
