Sovereign roofing products are designed to provide water resistance and integrity. Sovereign K10 is a black or grey roof repair and waterproofing compound. K10 can be used as an emergency roof repair even in poor weather conditions as it can be applied to damp surfaces and is instantly water proof. Sovereign Flashing is a mastic coated aluminium foil for use to provide a watertight seal in various roofing applications. Where lead flashing has been used this should be sealed into its rebate with Sovereign Lead Sealant, a high performance low modulus neutral cure silicone that bonds well to metals and masonry. Where a seal is required during bad weather then Sovereign All Weather Sealant can be used to form a watertight seal around windows, doors, in gutters and on roofing materials.
