Quality Assurance Contents:
Three Primary Requirements for a Maximum
Performance Roof System
2. Require a Fields Certified Roofing Contractor: Require contractors certified by Fields. These installers are skilled, trained, and familiar with Fields designs and products, and they install the highest quality roof systems. Fields Certified Contractors are the top roofing companies in the United States; They provide the critical installation factors for a roof system that will yield maximum performance.
3. Do Regular Inspections & Timely Maintenance: Do periodic inspections, minimize degrading environmental factors, restrict foot traffic, and complete timely maintenance. A good maintenance program is the best assurance of a successful, long term roof system, that will yield maximum performance.
1. Specifications and drawings have been read and understood by the responsible parties and are available for review on the project site.
2. All required certifications and approvals have been received for deck and roof components and are available for review on the project site.
3. Supplier literature and installation specifications are available on the project site for information and review.
4. Safety precautions and an MSDS for each product have been reviewed and are on the project site during installation.
5. Only the products specified are on the project site and are verified as to the correct quantity and type for the installation of the project.
6. Products are stored on pallets, covered from the weather, and protected from damage.
7. Roofing equipment is in good condition and functioning as designed.
8. Perimeter nailers, curbs, drains, and penetrations are in place prior to starting the roof system installation.
9. Drainage patterns are confirmed to yield positive drainage.
10. Specified fastener pullout tests are verified and the designer has approved the results with written verification on the project site for review.
1. Weather and project conditions are suitable for the roof system installation.
2. The substrate remains dry, frost free, clean, smooth, firm, and ready for installation of the roof system.
3. Nailers, drains, curbs, and penetrations are installed before installing the roof system.
4. Products are stored on pallets, covered from the weather, and protected from damage.
5. Only the products specified are on the project site and have been examined for defects, moisture, and damage.
6. Insulation boards are installed with joints staggered and offset between layers.
7. Insulation and base sheets that are adhered and installed with the specified type and quantity of Fields asphalt.
8. Insulation and base sheets that are mechanically fastened are attached with the quantity, pattern, and type of fasteners specified.
9. Water cutoffs are installed at the end of each day, and are removed before resuming the installation.
10. Asphalts are monitored to ensure that they are the correct class and type per the specifications.
11. Asphalt heating temperatures are maintained in drums, kettles, and tankers so as to ensure that hot applied asphalts are within the correct EVT range at the point of application; and that ambient applied asphalts are between 80° F and 120° F at the point of application.
12. Asphalt thermometers are visible, calibrated, and operating correctly.
13. Machine spreader holes are open and the hot asphalt at the point of application is flowing sufficiently for correct sheet adhesion.
14. A continuous flow of asphalt adhesive is being applied no more than 10 feet in front of the sheets being unrolled.
15. Sheets are being broomed smooth into the asphalt so that a continuous film of asphalt adhesive exists between sheets. No where does sheet touch sheet.
16. Sheet laps are completely adhered into the asphalt with a minimum of 1" asphalt adhesive exposure along the seams.
17. The specified quantities of ply sheets are being installed with the correct shingling of side laps.
18. All sheets are installed so that the flow of water is over or parallel to the seams, but never against the seams.
19. Sheet envelopes are installed at curbs, perimeters, and deck penetrations.
20. Flashing membranes are installed and reflective surfaced or glaze coated by the end of each day up through the completed roof system.
21. Reflective surfacings are applied as specified.
22. In high construction traffic areas, protection boards are in place over the newly installed roof system.
23. Other trades are not abusing the installed roof system.
Asphalt applicators shall be well trained in the specified installation and asphalt application rates. Applicators shall also be knowledgeable of the capacity of asphalt container equipment and the length of the asphalt layers that may be applied ahead of the rolls so as to obtain relatively uniform asphalt application rates and good sheet adhesion.
