On June 8th 2018 hailstorm with extremely huge hailstones of 10 cm (!) in diameter hit South East region of Slovenia. Most devastated was Črnomelj municipality with 1700 distroyed roofs. GERARD roofs proved again to be hail resistant. In spite of extreme size of hailstones, GERARD roofs remained waterproof. At GERARD Europe we did something for a good cause and donated materials for 1000 m2 roof for Kindergarten in Črnomelj.
