Good roofing tiles must have the basic qualities like water resistance, and heat resistance. Another quality is that the weight of the tiles should be less. Ideally if the tiles have an anti skid quality it is a great to walk on all year round. So it has to be eco friendly. At Restore we have such brands of tiles that are ideal with anti algae/fungi properties. We also offer high quality roofing tiles that have a superior Surface Regularity (SR) value which is a British standard. Since summers are severe in many places it is required to have roofing tiles with high Solar Reflectivity Index (SRI) too!
