Copper Flashing - 16 oz 24 Gauge 10' Rolls in Various Widths for Roofing, DIY, or Contractor use-Lead Free Copper - can be Used with Pressure Treated Lumber (2" Width)

Product Information

Chimneys need flashing to prevent water pooling between the chimney fixing and the roof. They tend to use a combination of different roof flashing types to create the most effective seal. On nailable sheathing, the flashing should be fastened with wide head nails or cleats. Nailing through flashing prohibits movement and should be avoided when movement is expected. The nail should be driven just above the upper edge of the flashing, allowing its wide head to hold the copper sheet. Nails or cleats should be spaced no more than 12" O.C.

Different slate profiles, roof materials such as corrugated roofing, roof pitches and the number of windows you’re installing all impact which flashing is most appropriate.Adhesives: Type recommended by flashing sheet manufacturer for waterproof/weather-resistant seaming and adhesive application of and compatibility with flashing sheet.

Coordinate work of this section with interfacing and adjacent work for proper sequencing. Ensure weather resistance and durability of work and protection of materials and finishes.

There are several parts of your roof that you may not even think about that require flashing, such as around your chimney or around your windows and skylights. Here are some of the main parts of your roof that you should consider applying flashing to: Fabricate counterflashings and reglets as 2 piece assemblies to permit installation of counterflashing after base flashings are in place. Install expansion joints at frequency recommended by CDA. Do not fasten moving seams such that movement is restricted.Description: Copper flashing is used wherever a wall intersects a roof. Such a system usually consists of copper counterflashing and base flashing in conjunction with roof composition flashing or coping. The counterflashing diverts water to the base flashing, which, in turn, diverts it to the composition flashing. The base flashing is designed to accommodate building movement. It laps the composition flashing at least 4". The composition flashing is extended up a cant strip then up the wall at least 10". Available Products: Subject to compliance with requirements, products that may be incorporated in the Work include, but are not limited to, the following:

Soft zinc" is a newer, proprietary flashing material. 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. [13] Types [ edit ] The flashing visible here is the apron below the dormer and the valley flashing in the open valley. The step flashing (soakers) are properly installed underneath the roof and wall shingles and thus is not visible. Hôtel Demoret Moulins, France Aluminium– Arguably the most commonly used material, it is easy to form and shape as needed and is also lightweight. Copper: Copper flashing is notoriously the most expensive option of the various flashing materials, but for a good reason. Besides being the strongest of the various types of roof flashing, it is perhaps also the most eye-catching—copper is a great color to match the style of most homes. Lead is traditionally used as a flashing material around upstands in roofs, such as chimneys because of its durability. The minimum specification that should be used is Code 4 lead (1.8 mm) which is both malleable and resistant to fatigue splits that could be caused by expansion and contraction. Code 3 (1.32 mm) is thinner, lighter and cheaper, and is commonly used for lead soakers which are the concealed waterproof sections positioned underneath slates and plain tiles.

Drip edges– Installed on the edges of roofs, drip edges guide water away from the fascia, preventing water from getting under the shingles or gutter.

Where required, provide for movement at joints by forming loops or bellows in width of flashing. Locate cover or filler strips at joints to facilitate complete drainage of water from flashing. Seam adjacent flashing sheets with adhesive, seal and anchor edges in accordance with manufacturer's recommendations.The origin of the term flash and flashing are uncertain, [2] but may come from the Middle English verb flasshen, 'to sprinkle, splash', related to flask. [3] Roofing material is an important consideration, but one thing you additionally must consider is your flashing material. You have a number of types of roof flashing to meet a variety of needs and budgets. EDIT EXAMPLES BELOW BY DELETING ITEMS NOT REQUIRED, ADDING OTHERS, OR REVISING TEXT TO CLARIFY DESCRIPTIONS. Fabricate corners from one piece with minimum 18-inch (450-mm) long legs; solder for rigidity if required; seal non-soldered weather joints with sealant.
