Metal Roofing - May 2018

Metal roofing featured in Metal Architecture's May 2018 issue.

Garland’s R-Mer Span structural standing seam metal roof system has a tight curving capability (steel: 20-foot radius; aluminum: 10-foot radius). It can be used on slopes down to 1/4-inch per foot. The R-Mer Span structural standing seam roof system has a 2 3/8-inch-high vertical seam.

Drexel Metals’ DMC 175S metal roof panel has a broad width seam and structural capabilities. The panels are installed with a snap-lock design. The continuous, interlocking roof system has concealed fasteners and clips that allow thermal movement and does not require mechanical seaming.

IMETCO's Series 300 metal roof panels have a symmetrical design that increases production and reduces scrap. The panels may be installed simultaneously in both directions from a central starting point to finish hips and valleys. One-piece clips provide thermal movement. Series 300 panels do not require field-notching or hemming.

Melathron’s Mela_dRain 540 standing seam roof system has drainage joints with dual, overlapping draining channels without fastening holes. The panels are installed with brackets and without sealants or gaskets. Re-flanging panels in the front creates a fold that prevents water from going into gutters and ridges.

McElroy’s 238T standing seam roof system can be used to roof-over an existing roof. It is an easy-to-install symmetrical standing seam system. The standing seam roof system features wind uplift and strength characteristics. Individual panels can be replaced, and panels can be roll formed in long lengths.

Petersen Aluminum’s Snap-Clad metal roof panels are produced in continuous lengths. They are corrective leveled for flatness. An optional factory-applied sealant bead is offered for weather resistance. Their maximum length is 64 feet and minimum length is 4 feet. The panels have a 1 3/4-inch leg height.
