If you're new to the roofing market or looking to do a roofing job of your own, your mind is sure to be boggling at the extensive range of lead flashing rolls that are available in a wide range of different thicknesses and sizes. The question you'll most probably be asking yourself is, 'which lead code do I need for my project?'. Getting the right lead code for your project is imperative to the overall finish and lasting performance of your roofing job, and most lead applications will fail if the incorrect lead size has been used. This will almost always happen if you use lead that is applied in sheets, which is where lead rolls in different thicknesses and codes comes into play. Each lead code is designed for a particular roofing job, and all rolls have been manufactured to meet BSEN 12588. So whatever roofing application you have lined up, make sure you're clued up on all the lead codes so you choose the right lead code for your job.
What Are The Thicknesses of Each Lead Code?
Lead flashing rolls are available in 6 different thicknesses, from code 3 up to code 8 and they're a popular choice for lead flashing rolls thanks to its long lasting durability and workable nature, they work exceptionally well for a wide range of roofing applications from flashing to guttering. The lower the lead code the lower the thickness, here are the following thicknesses and weights of the different lead codes:
Code 3 - 1.32mm - 14.97kg
Code 4 - 1.80mm - 20.41kg
Code 5 - 2.24mm - 25.40kg

What Uses Are Each Lead Code Designed For?
Now that you have the run down of each lead thickness it may already give you a better idea at what type of thickness your project requires. As we mentioned earlier, our lead flashing is suitable for a number of roofing applications, as well as being 100% recyclable, flexible and reusable, regardless of the weather conditions that it may face over the course of its lifespan. All of our lead flashing also comes in a popular grey colour which helps to achieve an aesthetically pleasing finish, and a popular choice for use on traditional slate and tiled roofs as waterproof flashing, guttering and water coursing. So, what projects are each lead code designed for? Most of the lead codes do cross over with one another so they can sometimes both be used for the same purpose, but some rolls like code 3 is only designed for use with soakers due to its thickness. Here is a run down of what each code can be used for:
Code 3 - Soakers
Code 4 - Soakers, flashings, pitched valley gutters, dormers, and vertical cladding
Code 5 - Flashings, pitched valley gutters, parapet, box and tapered valley gutters, dormers, vertical cladding, and flat roofing
