Roof Materials

The Vail Valley Foundation envisioned an iconic entrance for the amphitheater that not only would accommodate guests, protect against the elements and provide facilities, but also would recognize and celebrate the Ford family and mirror the amphitheater’s atmosphere.

Under the Vail Valley Foundation, Zehren’s team of architects chose approximately 5,500 square feet of PTFE fiberglass membrane canopies to make the vision for The Lobby a reality. PTFE, or polytetrafluoroethylene, is a Teflon-coated woven fiberglass membrane that is durable and weather resistant. The PTFE fiber coating is chemically inert, capable of withstanding extreme temperatures and immune to UV radiation.

Building Report

The Gerald R. Ford Amphitheater is a remarkable outdoor venue nestled along a hillside with a stunning view of the Rocky Mountains. The Lobby, which is adjacent to the Betty Ford Alpine Gardens and Ford Park, serves not only as an impressive entrance to the amphitheater, but also as a shelter from inclement weather, a social gathering point prior to entering the amphitheater, and a place for ticket and bag check. The Lobby allows for a smooth transition into the venue.

Within the Lobby resides a mini-stage that can accommodate pre-show performances, along with a new stand for concessions and restrooms. Around the perimeter of the space rests informal boulder seating, and alpine landscapes border the surrounding walls. Overall, the aesthetics of the space mirror the pristine landscape and enjoyable outdoor atmosphere.

The Lobby also holds a Ford family tribute: a series of symbolic sculptures and interpretive elements intended to pay homage to President and Mrs. Ford and their family. This tribute is a new landmark in Vail celebrating the family’s commitment to their adopted hometown and the positive changes that they made to the community.

Waterproof and Maintenance-free Roof Penetrations

The fewer people with access to the roof, the better chance the roof has at meeting the basic expectation of keeping the elements out of the building.

Pitch pockets are flanged, open-bottomed metal containers, placed around roof penetrations.

Because they make their living on the roof, commercial roofing installers know how to complete a watertight system, one that does not allow damaging moisture into the building. Unfortunately, when the roofing installer finishes the job, more work, perhaps by other trades, most notably HVAC contractors, may be done with possible impacts on the roofing membrane.

Someone has to get on the roof to install that equipment and at that point it’s going to be an equipment installer, not a roofing installer. It’s important to be aware of who is doing what on the roof!

Attaching equipment to the building structure, through the roof, is the most efficient method of attachment, but often such work is done without consideration of waterproofing concerns. Any attachment penetration must not compromise the integrity of the roofing system.

This is why RoofScreen Manufacturing got into the business: to discover and develop a better method for leak-proof attachment for all types of roofing and building structures.

The equipment installer has options. A traditional penetration waterproofing system is what is known as the pitch pocket. Pitch pockets are flanged, open-bottomed metal containers, placed around roof penetrations. They are filled with coal tar pitch, hot asphalt, grout or other chemical sealants. They are effective around odd-shaped penetrations but require maintenance, which means slapping on more sealant when it leaks.

Another method is the caulk and band method, commonly used on round penetrations, which employs a single-ply or soft lead pipe flashing around the penetration. Near the top of the flashing is an adjustable draw-band that clamps the flashing to the penetration. Caulking is applied around the top of the flashing to make the final seal.

Both practices are accepted by the National Roofing Contractors Association. The problem is both require annual or semi-annual maintenance to check if the sealant has cracked or separated from the penetration and addition of sealant as necessary.

RoofScreen offers a patented engineered and leak-proof roof attachment system to ensure the integrity of the roofing system. It starts with a 6- by 6-inch steel base support, available in a variety of lengths to accommodate any insulation thickness. The support is attached with bolts or lag screws to the roof structure through the interior of the base support. Specially fitted flashing boots are then installed and roofed in by a qualified roofing contractor. After roofing is completed, a self-adhesive EPDM gasket strip is applied around the top of the flashing, which provides added protection from snow, ice and splashing water. The final step is to install the Base Cap Assembly, which counterflashes 2.4 inches over the flashing and creates a seal by compressing the gasket. This watertight structural mounting point is ideal for mechanical equipment screens, equipment platforms and solar panel racking systems.

Many roofing manufacturers require penetration flashings to extend a minimum of 8 inches above the roof surface. RoofScreen has performed successful independent lab testing on its roof attachment system with only a 3-inch flashing height and had no leaks. Ultimately, it’s up to the roofing contractor and the roofing manufacturer to determine the flashing height in relation to the roof. Consult with both, especially if there is a roofing warranty involved.

If a base support needs to be raised to meet a required flashing height, RoofScreen offers 5-, 9- and 12-inch versions of the base support, plus 3- and 4-inch extensions. A taller base support should, in most cases, provide enough clearance for the amount of insulation being used. It should be noted the height of base supports impacts the overall design of the frame. RoofScreen provides fully engineered solutions incorporating all equipment screen variables.

In addition to installing a patented engineered leak-proof roof attachment system, RoofScreen eliminates the need for periodic maintenance. There will never be a need to add temporary caulking. With no need for maintenance, there’s one less reason for anyone being up on the roof to compromise the roofing system. That’s a good thing.

ROOF MATERIALS

The AceClamp ML is a standing-seam metal roofclamp system that can accommodate almost any application or roof seam. Its two-piece design allows installation at any point on the seam with a tight vibration-tested grip. All mounting holes are top-loaded, providing easy, quick access for the contractor, completing installation in less than half the time of conventional side-mounting systems. The AceClamp ML also does not penetrate or scratch the roof’s surface, preserving manufacturers’ warranties.
