HRGM was contracted through Whiting-Turner on a two phase project at Van Ness ES. The first phase involved removing the existing 16,000 SF roof and installing a new 80 mil PVC Sarnafil system. The second phase was far more involved including replacing some older roofs, installing new roofing, installing new ACM metal wall panels, Standing seam metal wall panels, as well as copingss, mechanical screen walls, gutters, downspouts, and a 3,000 SF green roof.
HRGM was contracted directly with DGS to remove the existing Modified Bitumen roof and replace it with a 72 mil Sika Sarnafil PVC. This project was very challenging due to the time constraints of completion as well as the very unique flashing and parapet details. The school had historic stone copings that had to be maintained, which led to some unique parapet flashing details. The project size was approximately 40,000 SF and was completed over summer break.
HRGM was contracted directly with DGS to remove the existing gym/multipurpose roof at Raymond ES and install a new White PVC roof and Architectural Decor PVC roof. The total roof size was approximately 8,000 SF, but unique because it used white PVC for the flat non-visible portions and Dark Lead Gray Decor PVC for the visible sloping roof portions. The Decor PVC roof mimics a standing seam metal roof, so it kept the same aesthetics as the previous roof but increased its performance.
HRGM was contracted to perform a complete tear-off and replacement of 3 roofs, 2 walkways, and 2 stairwells totaling approximately 43,000 SF (430 squares). HRGM installed a new, fully adhered fleeceback Hyload system over both structural steel and concrete decking. We installed new flashings, drains, and metal copings.
New construction of Versico 2 metal roofs and 1 EPDM roof. Approximate roof replacement included 30,000SF total. In addition, HRGM installation of metal wall panels, exposed metal trim and fascia units, pre-finished rain water leaders, downspouts and gutters. Metal Wall panels were fabricated onsite due to the length required for each panel.
HRGM performed a combination of new roofing and modifications to the existing roofing system to complete the repair of the River Terrace Elementary School. We installed a new Sarnafil PVC roof complete with radius and arched metal. We installed 100 Solatube skylights, 3 pyramid skylights, and 5 domed skylights. We installed 18,000 SF of route and seal composite metal panels. The total roof size was 86,000 SF.
HRGM was contracted to remove and replace historic natural slate roofing, approximately 16,000 SF, including installation of copper cornice. We tuck-pointed the chimney brick, repaired concrete coping, removed and replaced deteriorated wood. We repaired the decking and installed a WeatherBug HD Weather Station.
HRGM was contracted to complete a tear of of the existing roof. We removed approximately 15,000 SF (150 squares). We installed a new Firestone 60 mil TPO roof with tapered insulation. Work included demolition of skylights, fascia, and metal coping. We fabricated new metal in-house and installed.
HRGM performed a complete tear off and replacement of the existing roof at West Elementary School in DC. We installed new Sarnafil Décor PVC roof. This product is intended to look like a standing seam metal roof and involved careful welding of the Décor strips to membrane. We also fabricated and installed counter-flashing and drip edges.
