Flashing weatherproofing Wikipedia. Weatherproofing seam between a stone chimney and a tile roof on a building in Jersey, Channel Islands. The lead flashing is seen as light gray sheets at the base of the chimeny. 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. In modern buildings, flashing is intended to decrease water penetration at objects such as chimneys, vent pipes, walls, windows and door openings to make buildings more durable and to reduce indoor mold problems. Metal flashing materials include lead, aluminium, copper,1stainless steel, zinc alloy, and other materials.

Strips of lead used for flashing an edge were sometimes called an apron,5 and the term is still used for the piece of flashing below a chimney. 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. PurposeeditBefore 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 the 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. Moreover, flashing is important to ensure integrity of the roof prior to a solar panel installation.

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. MaterialseditIn earlier days, birch bark was occasionally used as a flashing material. Most flashing materials today are metal, plastic, rubber, or impregnated paper. Metal flashing materials include lead, aluminium, copper,1 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 steel, and metals similar to stone coated metal roofing. Metal flashing should be provided with expansion 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 react chemically with them. An important type of potential chemical reaction between metal flashing materials is galvanic corrosion.

Salt spray in coastal areas may accelerate corrosion. Types of flexible flashing products are rubberized asphalt, butyl rubber, polyvinylidene fluoride sometimes known as kylar or hylar, and acrylic. The different types have different application temperature ranges, material adhesion compatibility, chemical compatibility, levels of volatile organic compounds, resistance to ultraviolet light exposure. No flexible flashing material is designed to remain exposed over the long term as are metal flashing materials. Adhesive backed materials are convenient during installation, but such adhesives are not intended for long term water resistance. 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. Since flashing is expensive to replace if it fails, coppers long life is a major cost advantage. Cold rolled to 18 hard temper copper is recommended for most flashing applications. This material offers more resistance than soft copper to the stresses of expansion and contraction. 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.
