PART 2 - EXECUTION

3.01 BASE FLASHINGS

A. Preparation:

1. Remove existing flashing materials to substrate. Replace damaged material in like kind.

2. Prime vertical substrate with asphalt primer at approximate rate of one gallon per 125 - 150

sq. ft.

3. Install new roofing two inches beyond top edge of cant.

B. Base ply(s):

1. Fully adhere two (2) plies of specified base flashing completely to flashing substrate, cant, and roofing. Flashing should extend a minimum of 8" and maximum of 14” above finished roof membrane.

C. Cap ply:

1. Fully adhere a flashing top ply over base ply(s) in specified flashing adhesive.

a. Flashings may be adhered in specified flashing adhesive or torch applied up to 12" high.

b. Flashings must be adhered in specified asphalt mastic or fully adhered with torch applied above 12" in height.

2. Mechanically fasten top of flashing to substrate, fasten minimum of 8 inches on center.

3. Seal top edge with a 4 inch wide stripping membrane embedded in alternating courses of specified Asphalt Mastic.

4. Strip in bottom edge of flashing with 4 inch wide stripping membrane and specified flashing adhesive.

5. Surface flashing with specified protective coating (if specified).

6. Install specified counterflashing system as per detail drawings.

D. Additional instructions for mineral surface flashing cap.

1. Snap a chalk line 6” from the toe of cant out onto roof membrane.

2. Measure the distance from the chalk line up the wall to where flashing will be terminated.

On sloped roofs, take two measurements 1 meter (39” ) apart.

3. Measure down length of a roll of specified membrane, and cut, in cross machine direction, a section same length. If roof is sloped, start at the bottom, and transfer height measurement to cutting of the flashing cap. Each section is 1 meter (39”) in width.

4. Apply section in specified adhesive using a strapping method, overlapping the exposed smooth selvage with each new section. Bottom of flashing cap must be lined up 6” from toe of cant, on chalk line.

5. The salvage of the last section should be cut flush to the mineral surface prior to the application, ensuring that total flashing surface is mineral surfaced.

6. All areas where excessive adhesive is exposed on side laps may be coated with specified heat reflective coating or granules sprinkled in as flashing sections are installed.

E. Additional instructions for metal clad flashing cap

1. Calculate the length of membrane required covering the flashing or curb.
