Flashings integrate your roof window perfectly into the roofing material, ensuring that your window is completely weathertight, whatever the conditions. We offer a range of flashings designed for different roofing materials. Installing the correct flashing for your roof window also ensures your guarantee remains valid. If you would like to order combination flashings (twin, vertical, triple, combi etc) then please give us a call on 0203 598 6509 to discuss your requirements.
