Chimney Copper Flashing Contractor Asbury Park NJ 07712

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 Asbury Park NJ 07712.

Copper is an excellent material for flashing in Asbury Park NJ 07712 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, copper’s long life is a major cost advantage. Cold rolled (to 1/8-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 in Asbury Park NJ 07712. Thermal movement in flashings is prevented or is permitted only at predetermined locations.

Soft zinc is another flashing alternative gaining popularity. Soft zinc is an exceptionally malleable material, making it extremely useful for complex roofing connections. This material provides normal soft soldering capabilities and delivers easy folding in Asbury Park NJ 07712. Soft zinc is an environmentally friendly solution for replacing lead flashing; it is completely recyclable and provides 100% clean runoff.

Before the availability of sheet products in Asbury Park NJ 07712 for flashing carpenters used creative methods to minimize water penetration such as angling roof shingles away from the joint, placing chimneys at the ridge, and building steps into the sides of chimneys to throw off water. The introduction of manufactured flashing decreased water penetration at obstacles such as chimneys, vent pipes, walls which abut roofs, window and door openings, etc. thus making buildings more durable and reducing indoor mold problems. In builders books, by 1832 Loudons An Encyclopædia of Cottage, Farm, and Villa Architecture and Furniture... gives instruction on installing lead flashing and 1875 Notes on Building Construction gives detailed instruction and is well illustrated with methods still used in Asbury Park NJ 07712 today.

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 Asbury Park NJ 07712.

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 Asbury Park NJ 07712 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.
