ROOF TESTING AND CERTIFICATION
Gerard tiles are consistently tested for quality consistency in both our own laboratories and independent testing stations. Tiles from every batch produced every day are picked at random and tested to ensure our quality standards are met in a series of measures. For international certification, independent external laboratories test Gerard tiles and accessories to ensure they meet the high standards set by them and by countries around the world.
