ATTACHMENT 1
Please read this disclaimer prior to using the Uplift Pressure / Fastening Pattern Tool referred to here as the "Tool".

This Tool can be used to generate expected uplift pressures on roofs using calculations in accordance with ASCE 7 (05, 10 or 16) standards.

The uplift pressures are used to generate a report that can be reviewed by a licensed Engineer, when required, and/or utilized to determine tested roof assemblies appropriate for a roofing project. The Tool also utilizes these pressures to create a report outlining roof system fastening patterns (for mechanically fastened systems only) which will meet Duro-Last's requirements for the roofing project.

The proper calculation of uplift pressures and fastening patterns is reliant upon information provided by the user of this Tool, the accuracy of which Duro-Last has no control over. The user of this Tool is responsible for seeking assistance, if necessary, in order to provide accurate information.

The user of any report created with this Tool is solely responsible for its content and accuracy with respect to complying with Duro-Last Roofing Specifications, project requirements and all applicable regulatory codes. These calculations do not take precedence over local building codes.

Duro-Last, its employees and independent sales personnel representing Duro-Last EXPRESSLY DISCLAIM any and all responsibility for any errors, omissions or misrepresentations and are not liable for damages (direct or consequential, including but not limited to loss of profits) or damage to buildings or their contents, with respect to the use of this Tool and/or any reports created through its use.

C. Verify that the deck is clean and smooth, free of depressions, waves, or projections, and properly sloped to drains, valleys, eaves, scuppers or gutters.

D. Verify that the deck surfaces are dry and free of standing water, ice or snow.

E. Verify that all roof openings or penetrations through the roof are solidly set.

F. If substrate preparation is the responsibility of another contractor, notify Architect of unsatisfactory preparation before proceeding.

3.2 PREPARATION
A. Clean surfaces thoroughly prior to installation.

B. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.

C. Surfaces shall be clean, smooth, free of fins, sharp edges, loose and foreign material, oil, grease, and bitumen.

D. Re-Roofing Over Existing Single-Ply System:

1. Remove all loose or high fasteners.

2. Membrane contaminated with bitumen must be immediately cleaned. If cleaning does not remove the bitumen, the contaminated membrane must be replaced, or covered with both a slip sheet and new membrane.

4. When the system is smooth or granular-surfaced, any approved slip sheet, insulation or cover board may be used to provide separation of the roof system and new membrane. Duro-Guard fan folds may be used if the surface is pea gravel or crushed stone which is ¼ to 3/8 inch in size and has been leveled and maintained at 4 psf. For larger rock/gravel, utilize an approved rigid insulation or cover board.

5. If rock/gravel surfacing is removed, an approved fan fold, rigid insulation or cover board must be used.

If embedded rock/gravel remains that protrudes out of the deck more than ¼ inch, do not use fan fold board. Instead, use an approved cover board or rigid insulation.

6. When installing polystyrene insulation over coal tar pitch or asphalt-based roof systems, a slip sheet must be used between the insulation and existing roof.
