MFM Building Products Underlayment Can Be Used in Vertical Applications

Ultra HT Wind & Water Seal MFM Building Products, a manufacturer of a full envelope of waterproofing and weather barrier products for the building industry, announces that its Ultra HT Wind & Water Seal high-temperature roofing underlayment can be used for vertical side wall applications.

This self-adhering “self-stick” membrane is composed of a cool white, cross-laminated, high density polyethylene film laminated to a high-temperature rubberized asphalt adhesive system rated to 250 degrees Fahrenheit. According to the manufacturer, this premium product is extremely tough, is self-sealing around fasteners and offers a 90-day UV exposure rating.

The company states that Ultra HT is ideal for vertical applications under metal panel systems and parapet walls capped with metal tiles. The high-temperature adhesive system withstands the high temperatures generated by these systems to ensure complete waterproofing protection. Special installation instructions must be followed for all vertical applications.

Ultra HT has a thickness of 45 mils and is available in a 12-inch, 18-inch and 36-inch by 67-foot length rolls. As a roofing membrane, Ultra HT meets ASTM D 1970, Florida Building Code FL16562, and Miami-Dade County NOA 13-1125.06. The product comes with a 10-Year Limited Warranty.

ROOF MATERIALS

Wagner Roofing was awarded the complete replacement of all roof systems. These included an upper double-lock standing-seam copper roof system, a bullnose copper cornice transition, slate mansard, 34 dormers with double-lock standing-seam copper and fascia metal, eight copper hip metal caps and a continuous built-in gutter with decorative copper fascia. Each of the dormers also had a copper window well.

The upper standing-seam roof was removed and replaced with 24-inch-wide, 20-ounce copper coil rollformed into 1-inch-high by 21-inch-wide continuous standing-seam panels that matched the original profile. The eave bullnose, which also served as the mansard flashing, was removed and returned to Wagner Roofing’s shop where it was replicated to match the exact size and profile.

The 34 dormer roofs were replaced with 20-inch-wide, 20-ounce copper coil formed into 1-inch-high by 17-inch- wide continuous standing-seam panels. The decorative ornate fascia of the dormers was carefully removed and Wagner’s skilled craftsmen used it as a template to develop the new two-piece copper cornice to which the roof panels locked. The cheeks and face of the dormers were also re-clad with custom-fabricated 20-ounce copper.

The oversized built-in-gutter at the base of the slate mansard was removed and replaced with a new 20-ounce copper liner custom-formed and soldered onsite. The replacement included a specialty “bull-nosed” drip edge at the base of the slate and an ornate, custom-formed fascia on the exterior of the built-in gutter. The decorative copper fascia included 85 “hubcaps”, 152 “half wheels” and 14 decorative pressed-copper miters. The original hubcap and half-wheel ornaments were broken down and patterns were replicated. Each ornamental piece was hand assembled from a pattern of 14 individual pieces of 20-ounce copper before being installed at their precise original location on the new fascia. The miters were made by six different molds, taken from the original worn pieces, to stamp the design into 20-ounce sheet copper.

In all, more than 43,000 pounds of 20-ounce copper was used on the project.

ROOF REPORT

Maury Hall was built in 1907 and was designed by Ernest Flagg. Flagg designed many of the buildings at the U.S. Naval Academy, including the Chapel, Bancroft Hall, Mahan Hall, the superintendent’s residence and Sampson Hall. His career was largely influenced by his studies at École des Beaux-Arts, Paris. Examples of Flagg’s Beaux-Arts influence can be found in the decorative copper adorning the built-in gutter on building designs.

Maury Hall currently houses the departments of Weapons and Systems Engineering and Electrical Engineering. The building sits in a courtyard connected to Mahan Hall and across from its design twin, Sampson Hall.
