It is critical that lead panels are allowed to move freely whilst still remaining watertight. This is best achieved by the use of a wood cored roll joint as illustrated. Multi-roll is supplied in 2.4 Metre lengths and is vac-vac treated against rot. |

| A full range of lead working tools are available, manufactured from beech. The range includes dressers (for flattening lead) bossing sticks, bending sticks and mallets (for shaping lead) setting in sticks (for setting corners) and chase wedges (for compressing lead wedges). | It is often necessary to fix lead with an external fixing, the only decorative way too achieve this is with a lead Dot or Rose. Both are available with or without brass screws, the latter can be fixed to the lead sheet by lead burning |
