3.3 INSTALLATION

A. Install modified bitumen membranes and flashings in accordance with manufacturer's instructions and with the recommendations provided by the National Roofing Contractors Association's Roofing & Waterproofing Manual, the Asphalt Roofing Manufacturers Association, and applicable codes.

B. General: Do not installing modified bitumen membranes at temperatures lower than 40-45 degrees F wherever practicable. Where work is unavoidable at such temperatures the following precautions be taken:1. Take extra care during cold weather installation at ambient temperatures of 40-45

degrees F or below and when ambient temperatures are affected by wind or humidity, to ensure adequate bonding is achieved between the surfaces to be joined. This applies to both material seam welds and adhesion of the applied product to the appropriately prepared substrate as the substrate can be affected by such temperature constraints as well.

2. In addition, unrolling of cold materials, under very low ambient conditions must be avoided to prevent the likelihood of unnecessary stress cracking. Rolls must be at least 40 degrees F at the time of application. Should the membrane roll become stiff or difficult to install, it should be replaced with a new roll from the heated storage area.

C. Commence installation of the roofing system at the lowest point of the roof (or roof area), working up the slope toward the highest point. Lap sheets shingle fashion so as to constantly shed water

D. Base and Ply Sheet Installation:1. Install in a manner approved for the specific product, e.g. fully adhered as self-

adhered or with asphalt adhesive, torch applied or mechanically attached.2. Base or Inter-ply side laps are to be 3 inch minimum and usually delineated by a "lay

line" for mopped, torch or mechanically attached application. End laps are typically 6 inches in all cases.

E. Self-Adhered Application: Base or ply sheet shall be installed per Polyglass specifications and installation guidelines appropriate for the specific substrate type and thickness.

F. Torch Application: The use of shielded "Dragon-wagons", or moveable, flame-resistant wind

07 52 00-33

shields are recommended to keep all surfaces and materials at a suitably warm temperature during torch application.

G. Mop Application: Asphalt handling equipment should be insulated in order to minimize the drop in asphalt temperature.1. Asphalt must be at least 400 degrees F with a target temperature of 425 degrees F or

20 degrees F above the EVT (equiviscous temperature), whichever is higher, at the point of application.

2. If minimum asphalt temperature of 400 degrees F cannot be maintained at the point of application, work should be discontinued.

3. Do not overheat asphalt to compensate for cold weather conditions.4. Mopping should not progress more than 4 feet in front of the roll at any time.

H. Cold Adhesive Application: Install base, ply and cap sheet with Polyglass Polyplus 35 or PG 350 Modified Bitumen Adhesive in accordance with Polyglass specifications and installation guidelines.

I. Fibrous Cant Strips: Provide non-combustible perlite or glass fiber cant strips at all wall/curb detail treatments where angle changes are greater than 45 degrees. Cant may be set in approved cold adhesives, hot asphalt or mechanically attached with approved plates and fasteners.

flashings and sheet metal components.2. Wood nailers should match the height of any insulation, providing a smooth and even

transition between flashing and insulation areas.3. Nailer lengths should be spaced with a minimum 1/8 inch gap for expansion and

contraction between each length or change of direction.4. Nailers and flashings should be fastened in accordance with Factory Mutual "Loss

Prevention Data Sheet 1- 49, Perimeter Flashing" and be designed to be capable of resisting a minimum force of 200 lbs/lineal foot in any direction.

K. Metal Work: Provide metal flashings, counter flashings, parapet coping caps and thru-wall flashings as specified in Section 07 62 00 - Sheet Metal Flashing and Trim or Section 07 71 13 - Manufactured Copings. Install in accordance with the SMACNA "Architectural Sheet Metal Manual" or the NRCA Roofing Waterproofing manual.

L. Termination Bar: Provide a metal termination bar or approved top edge securement at the terminus of all flashing sheets at walls and curbs. Fasten the bar a minimum of 8 inches o/c to achieve constant compression. Provide suitable, sealant at the top edge if required.

M. Flashing: Use Polyglass flashing sheets and minimum 6 inch wide Polyglass stripping sheets. Install stripping sheet with a minimum of 3 inches in both horizontal and vertical surfaces. Install flashing sheets with a minimum of 6 inches on horizontal surface and extended a minimum of 12 inches above finished roof surface.1. Install flashing sheets by the same application method used for the roof membranes.

In hot mop applications the flashing sheets may be installed by heat weld application provided the proper flashing materials are utilized.

2. Heat and scrape granules when welding or adhering at cut areas and seams to granular surfaces at all flashings.

3. Secure the top edge of the flashing sheet using a termination bar only when the wall surface above is waterproofed, or nailed 4 inches on center and covered with an acceptable counter flashing.

4. Items related to re-roofing operations such as sheet metal gravel stops, roof vents, and similar items shall be incorporated into the new roof system in accordance with
