All professional roofers will know of the risks involved in roofing, and that’s because every year people are seriously injured by falling through a fragile roof. This is why it’s important to step safely, especially on old roofs which require repairs, and roofs with skylights.
Polycarbonate skylights can resist torrid weather conditions but they’re not always strong enough to withstand the weight of human being, and all roofer should know not to step on a rooflight, unless of course it’s a walk-on glass rooflight.
Repairs should always be carried out working from underneath, while safety nets or harnesses should be used if you have to work on top of a building. Make sure you step safely, and look out for any hidden fragile areas.
