Our BSI certified lead flashing rolls from UK standard milled lead specialist, Central Milled Lead (CML), is available in codes 3-8 covering every type of thickness you might possibly need for your roofing job.
The primary function of lead flashing is to prevent water egress into a building through the joints. This, for example, might be at a chimney, wall abutment, roof window or valley gutter.
Each application has a recommended flashing code for it. Using the right thickness of flashing will ensure thermal expansion and contraction does not compromise the flashing and cause cracking.
Our lead roof flashing comes in 3m and 6m rolls with widths starting at 150mm rising to 1000mm. However, there is no limit to how specific your lead flashing roll can be.
Any code lead can be cut to size bespoke to your requirements. Naturally, this will come at a slightly higher price than our standard widths, but will mean no extra cutting or waste. Call us on 01303 883108 for made to measure lead flashing.
Lead Flashing Codes
British Standards lead codes should be followed when purchasing your lead. Certain codes are needed for certain applications. Thinner Code 3 lead flashing roll is perfect for soakers, while pitched valleys and flat roofs require a code between 5 and 8.
Regardless of code, best practice states that individual pieces of lead flashing should not be any longer than 1.5m and no shorter than 75mm. Lead any longer than this is more likely to split through thermal movement.
General rule of thumb on lead flashing also dictates lead roof flashing should overlap by a minimum of 100mm when fitting.
Benefits of Using Lead
As well as being the most recycled building material in use today, lead will last longer and age better than other materials.
Lead is quick and easy to install for professionals in most weather conditions and has few laps and joints. This results in a high degree of weatherproofing.
Lead flashing is proven to last up to 100 years- longevity greater than that of lead-free alternatives.
Lead Free Alternatives
We stock lead free flashing alternatives from well-known brands, such as Ubbink and Klober for next day delivery.
The biggest attraction of lead-free flashing is in its cost effectiveness. These aluminium based flashings are cheaper to buy than heavier lead and have no scrap value therefore reducing the likelihood of theft.
Lead free alternatives like BBA certified Ubiflex are also environmentally friendly and nontoxic, making it arguably safer to handle than lead flashing.
Lead free flashing can be used on many of the same applications as lead to provide a waterproof junction.
Ubiflex can be 50% quicker to install than lead reducing time on site and the associated costs, while aluminium soakers are an ever more economical solution when forming a pitched roof against an existing wall.
