Leadwork is an ancient age-old art that has been passed down through many generations throughout the years, and even in the recent advent of non-lead based alternatives, is by far the most commonly used material on our roofs today.
Our team of leadwork specialists take great pride in their work, using their high-level skills and time-served knowledge to ascertain the rates of thermal movement, they are able to not only completely secure any water ingress, but also provide aesthetically appealing workmanship that will stand the test of time.
From the full strip and removal of failed lead valleys, and fully new installed Code 4 lead replacements, complete with new valley boards, to complex dormer windows, full flat roofs, and every aspect of chimney flashings, our specialist teams can cater for all.
The term Flashing refers to thin pieces of impervious material installed to prevent the passage of water into a structure from a joint or as part of a weather resistant barrier (WRB) system. Flashing types are named by their location of uses or shapes:
- Roof flashing is placed around discontinuities or objects which protrude from the roof of a building to deflect water away from seams or joints and in valleys where the runoff is concentrated.
- Wall flashing may be embedded in a wall to direct water that has penetrated the wall back outside, or it may be applied in a manner intended to prevent the entry of water into the wall. Wall flashing is typically found at interruptions in the wall, such as windows and points of structural support.
- Sill flashing or sill pan is a concealed flashing placed under windows or door thresholds to prevent water from entering a wall at those points.
- Roof penetration flashing are used to waterproof pipes, supports, cables, and all roof protrusions. Stainless steel penetration flashings have proven to be the longest lasting and most reliable roof flashing type.
- Channel flashing is shaped like a U or channel to catch water such as where the edge of a tile roof meets a wall.
- Through wall flashing – Spans the thickness of the wall and directs water to weep holes.
- Cap flashing (drip cap) often used above windows and doors.
- Drip edge – A metal used at the edges of a roof.
- Step flashing (soaker, base flashing) – Pieces of flashing material which overlap each other in “steps”.
- Counter flashing (cap flashing) – Covers a base flashing.
- Pipe flashing – (pipe boot, vent boot) A product used where pipes penetrate roofs.
- Chimney flashing – A general term for flashing a chimney.
- Kickout flashing – At the very bottom of a roof/wall intersection, the lowermost step flashing specially formed to deflect water away from the wall.
- Valley flashing – In the valley of two intersecting roof planes.
A structure incorporating flashing has to be carefully engineered and constructed so that water is directed away from the structure and not inside. Flashing improperly installed can direct water into a building, so choosing the right tradesmen is imperative in this particular roofing dominion.
