Standing Seam Metal Roof

Standing Seam Metal Roof

Stand Up for Standing Seam

The versatility, long-term durability and low maintenance of standing seam metal roofs have made them a highly popular choice in many new, retrofit and re-roof applications.

Insulating with Dow products boosts the energy performance of the metal roof, further increasing its cost effectiveness. And when paired with rigid foam insulation from Dow (THERMAX™ products or STYROFOAM™ Brand DECKMATE™ Plus Extruded Polystyrene Insulation), WEATHERMATE™ Straight Flashing can provide excellent temporary protection against water penetration before the final roof is installed.
