Your GERARD roof can even defy a 160 km/h hurricane, which cannot damage your roof! No more broken tiles! No more tiles torn off your roof by a windstorm with stormproof GERARD roof!
To prove this to you we hired (our sister company in New Zealand) a plane with a 1500 KW aircraft engine. As a wind generator it provided the air stream equivalent of a 160 km/h hurricane. The roof remained firm and intact with no uplift whatsoever. Then we raised the stakes by adding water into the air stream to test leakages on the roof. But water could not get through GERARD!
