Faster Roof Sumps

Factory-assembled and pre-cut, the 4-ft. × 4-ft. Target Sump is a prefabricated polyiso panel sloped to direct water to flow to the integral drain. A coated glass facer adds dimensional stability and fire performance and resists mold growth—and it’s compatible with all major roofing membranes and application techniques.

Hartong Homestead in Green, Ohio

Bringing a Historic Roof up to Date

The original slate roof of the 1883 timber-framed Standard Pennsylvania-style barn on the historic Hartong Homestead in Green, Ohio, had deteriorated beyond repair. Braun & Steidl Architects were called in to oversee needed repairs. Single-Width composite tiles with a slate finish were installed. The composite slate was able to recreate the original appearance of the 1883 construction date.   

West Springfield High School, West Springfield, Mass.

Timing Was Everything

With at least 20 different elevation levels, the 146,000-sq.-ft. roof of the new West Springfield High School in West Springfield, Mass., posed some serious timing challenges for both installers and construction managers. Interior contractors couldn’t do finish work until the roof in those areas was watertight, so roofing schedules had to be closely coordinated with other trades. Using DensDeck Roof Board, topped by VapAir Seal 725TR self-adhered air and vapor barrier membrane, provided the necessary waterproofing and allowed interior work to progress while remaining roofing components, including the finishing layer of Sure-Flex PVC membrane, to be installed at their own pace.


Vegetated Solution

Designed to give a pre-vegetated garden roof option with a fully integrated assembly the InstaGreen GT-4 Tray features a uniquely structured bottom element that provides large amounts of water storage for plant use, as well as an aeration feature that helps ensure gas exchange can occur at the bottom of the media column. This water storage area is useful where stormwater management is a consideration.


Like Sunscreen For Your Roof

Duro-Shield Coatings are formulated from 100%- elastomeric acrylic and can seal to a range of single-ply membrane materials, along with metal, wood and built-up substrates, to protect roofs from UV damage and heat build up. The coatings create a bright white finish to reflect the sun.


Cool Roof Spotlight

Colonial Seam, a new residential standing seam metal roofing panel, is a clip-less panel from Accel Roofing Products, a division of ATAS, that offers a traditional standing seam aesthetic with contemporary factory-formed advantages. It is installed by locking the one-piece panel into the previous panel and fastening through pre-punched slots, allowing for expansion and contraction. All fasteners are concealed by the adjacent panel. The positive locking action makes it virtually impossible for the panels to slide apart. Panels are available in widths of 12.375-in. and 16.375-in., with a 1-in. seam height, in 0.032 aluminum and 24 gauge metallic coated steel. Both substrates have the same PVDF


Wear a Coat

Cool roofs can be achieved by other means. Guardian elastomer-based coating options, for example, can cost-effectively transform metal, BUR, modified bitumen and aged single-ply roofs into reflective roofs that can reduce building energy requirements. Roof Guardian RG-170 is a white finish coat with a solar reflectance index (SRI) of 109. Roof Guardian RG-180 is a fibered white coating (SRI 108) that achieves Class A fire rating. Both are Energy Star and CRRC rated. The waterproofing products are formulated using an acrylic polymer base for enhanced adhesion and durability, and both resist cracking and peeling. Roof Guardian products are also useful for gutterways, repairs and other projects

Air It Out

Ventilation and airflow also have their place in effective roof systems. For example, cool roof systems incorporate a combination of tile products designed to increase air flow and ventilation under tile with materials that reflect UV heat from the roof to reduce the amount of heat transferred into the structure. This translates into fewer on/off air conditioning cycles to maintain interior temperatures. Comparative testing has shown a heat transference differential of as much as 45 degrees on the underside of roof decking when simulated solar energy is directed at the tile installations compared to like-colored asphalt shingles using the same roofing materials.

The Phase II expansion includes more than 30,000-sq.-ft. of Snap- Clad panels finished in 3 complementary colors.

Roof Enhances Shopping Center’s Image

The major expansion of the Destin Commons shopping center in Destin, Fla., further establishes its reputation as the premier open air lifestyle center offering the best in shopping, dining and entertainment on Florida’s Emerald Coast. The Phase II expansion adds 100,000 sq. ft. to the 500,000-sq.-ft. family-oriented shopping environment. Destin Commons also includes 70,000 sq. ft. of Class A office suites. And the expansion included metal roofing; there were multiple buildings involved with various applications and complexities. Although Destin Commons is located less than one half mile from the Gulf in the corrosive saltwater environment, steel was selected for the project versus aluminum d


Rio Olympics Play It Cool

Rio de Janeiro played host to the 2016 Summer Olympic games, with 14,850 athletes from 206 countries participating in 32 sporting venues located in four districts of Rio de Janeiro: Barra, Copacabana, Deodoro and Maracaña. Materials for these roofs and façades at five major venues were critical due to the technically demanding nature of these projects, which combine architectural challenges and difficult climatic conditions.
