The up-hill side of a chimney may have a small gable-like assembly called a cricket with cricket flashing or on narrow chimneys with no cricket a back flashing or back pan flashing. Flashing may be let into a groove in a wall or chimney called a reglet.
Before the availability of sheet products for flashing builders used creative methods to minimize water penetration such as angling roof shingles away from the joint, placing chimneys at the ridge, building steps into Break metal flashing sides of chimneys to throw off water and covering seams between roofing materials with mortar flaunching.
The introduction of manufactured flashing decreased water penetration at obstacles such as chimneys, vent pipes, walls which abut roofs, window and door openings, etc. Flashing may be exposed or concealed. Exposed flashing is usually of a sheet metal and concealed flashing may be metal or a flexible, adhesive backed, material particularly around wall penetrations such as window and door openings. In earlier days, birch bark was occasionally used as a flashing Midget slate turkey. Metal flashing materials include lead, aluminium, copper,  stainless steel, zinc alloy, other architectural metals or a metal with a coating such as galvanized steel, lead-coated copper, anodized aluminum, terne -coated copper, galvalume aluminum-zinc alloy coated sheet steeland metals similar to stone-coated metal roofing.
Metal flashing should be provided with Free dildo masturbation ideos joints on long runs to prevent deformation of the metal sheets due to expansion and contraction, and should not stain or be stained by adjacent materials or Online dating sites ratings security chemically with them.
An important type of potential chemical reaction between metal flashing materials is galvanic corrosion. Aluminum is also damaged by wet mortar and wet plaster. Salt spray in coastal areas may accelerate corrosion. Types of flexible flashing products are rubberized asphaltbutyl rubberpolyvinylidene fluoride sometimes known as kylar or hylarand acrylic. No flexible flashing material is designed to remain exposed over the long term as are metal flashing materials. Copper is an excellent material for flashing because of its malleability, strength, solderability, workability, high resistance to the caustic effects of mortars and hostile environments, and long service life see: copper flashing.
This enables a roof to be built without weak points. Soft copper can be specified where extreme forming is required, such as in complicated roof shapes. Thermal movement in flashings is prevented or is permitted only at predetermined locations. It is a relatively malleable material, making it useful for complex roofing connections. It provides normal soft soldering capabilities and delivers easy folding. Soft zinc is said to be an "environmentally friendly" replacement for lead flashing; like lead, it is recyclable, while avoiding lead-contaminated runoff.
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. In the US and UK, at least, lead flashing and fittings are still readily available, despite the environmental concerns associated with bulk use of this heavy metal.
The Lead Sheet Association touts its recyclability and extreme durability, years, compared to modern materials that can fail within 20 years. From Wikipedia, the free encyclopedia.

When I was an architectural intern, working on construction documents, I often used details from previous projects to get started on details for a current project. But when I started writing specs, I learned that brake metal is sheet metal that is formed in a press brake. This metal is often specified for sheet metal flashing and trim.
