Flashing is usually a different material from your roof, but it plays an important function to your home by keeping the more vulnerable spots of your roof safe from the weather. Drawings and general provisions of Contract, including General and Supplementary Conditions and Division 01 Specification Sections, apply to work of this Section.

Product data for flashing, metal, and accessories: Manufacturer's technical product data, installation instructions and general recommendations for each specified sheet material and fabricated product. DESIGN PROFESSIONAL IS RESPONSIBLE FOR DESIGNING SYSTEM, INCLUDING ANCHORAGE, FASTENER SIZE, AND SPACING. EDIT EXAMPLES BELOW BY DELETING ITEMS NOT REQUIRED, ADDING OTHERS, OR REVISING TEXT TO CLARIFY DESCRIPTIONS. Install units plumb, level, square, and free from warp or twist while maintaining dimensional tolerances and alignment with surrounding construction.

After soldering, carefully remove flux and other residue from surfaces. Neutralize acid flux by washing with baking soda solution, and then flushing clear water rinse. Wipe and wash solder joints clean. Provide maintenance data in Operations and Maintenance manual for maintaining applied coatings on copper panels. Counter-flashing– This is paired with base flashing to protect the upper edge of the base flashing, creating a much stronger seal. Flashings and copings are fabricated from cold rolled copper in weights ranging between 16 and 20 ounces per square foot. The required weight depends on the application and is outlined in the discussion related to each detail. Install laminated flashing in accordance with manufacturer's recommendations. 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.Fit flashings tight in place. Make corners square, surfaces true and straight in planes, and lines accurate to profiles. The last two details show typical shelf angle flashing. These follow the same principles outlined in the first detail.

There are a wide range of roof flashing types that are used in different contexts. Some are designed for roofers to install around features such as chimneys, roof windows and vents. Others are designed to protect the roof where it meets the house wall. Fabricator's Qualifications: Company specializing in copper flashing and trim work with three years experience in similar size and type of installations.Most modern construction materials are fairly resistant to moisture penetration. However, many joints between masonry units, panels, or architectural features are not. The effects of natural movement due to settlement, expansion, and contraction tend to compound the problems and may eventually lead to leaks. Flashing is used to prevent moisture from entering at such locations. It is also used to divert to the exterior moisture that has already entered various components of a structure. It’s commonly made from aluminium. Copper is a longer-lasting solution, but is much more expensive. Expansion Provisions: Where lapped or bayonet-type expansion provisions in work cannot be used or would not be sufficiently water/weatherproof, form expansion joints of intermeshing hooked flanges, not less than 1-inch (25-mm) deep, filled with mastic sealant (concealed within joints). SELECT FLASHING, COPING, FASCIA/GRAVEL STOP, SCUPPERS, OR CONDUCTOR HEADS BELOW AS APPROPRIATE FOR PROJECT. Selecting the flashing that is right for your home comes down to your budget and the investment you are willing to put forth for a better and lasting material. Here are just a few of the most common options:

Install expansion joints at frequency recommended by CDA. Do not fasten moving seams such that movement is restricted. Available Products: Subject to compliance with requirements, products that may be incorporated in the Work include, but are not limited to, the following: You probably are familiar with the shingles on your roof, or whichever other type of covering keeps your home dry and safe. However, amidst these popular materials is the perhaps less popular but equally important roof flashing material.Through-wall flashing is used at all points where moisture may enter the wall, and in selected places particularly susceptible to water damage.
