Seasonal elements play havoc with building exteriors.   During winter you will hear newscasts  about the potential dangers of snow and ice build-up on flat and low-sloped roofs, especially vulnerable are steel pre-engineered buildings, where snow loads could exceed structural design.  The threat of collapse can literally loom over head during that time of year.  The meltdown of Spring with it's oftimes heavy wind and driving rain brings it's own particular difficulties.   Ponding, serious leakage and subsequent internal damage often occurs.  Your flat roof should be inspected at regular intervals.

Sometimes you can detect potential problem areas.   Here are some things to look for:

1. Abnormal bulging or deflection of roof structural support members.
2. Change in shape of interior ceiling materials.
3. Check all plant, secondary roofs, and porticos -- these locations are not usually designed to handle extreme loads of drifting snow from higher buildings.
4. Formulation of ice under the snow is where hidden weight accumulates.
5. Leaks, of course, are obvious indications of trouble spots.
6. Many industrial or commercial office locations are situated in lower buildings from main plants or facilities.  These places are particularly vulnerable to high drifting, packing snow, meltdown from other sources, and possible roof collapse.  In addition to leaking, the potential of structural failure is likely in these places.   If you notice any leakage inside office areas, protect your technical equipment, machinery, and information first.  Contact a professional for an assessment of your situation promptly.
7. Buildings with low insulation value may experience higher incidents of ice build-up and icicling due to building heat loss.
8. Many employers are having their own staff remove ice and snow from roof tops.   Staff may accidentally fall, damage the roof, or perforate the roof membrane.   This can be very costly, and can expose employees to undue hazard and risk.   Under these adverse conditions, the waterproof integrity of a roof is paramount.

We encourage that all roofs be inspected, as the costs of not acting can be enormous.  We can assist maintenance staff with recommendations for snow and ice clearing.
