White metal roofing saves energy costs
Aging commercial metal roofing begin to leak and to rust. This page quickly
illustrates the principal steps in stopping leaks, containing rust
and presenting the customer with an energy-saving white metal roof After
finishing the project, the building interior was cooler during the warm summer
In a private hanger facility, the plane owners expect to
house their beauties in a building free of leaks. Plus the hanger lacks air
conditioning. During the hot days, the coolest possible roofing would be
After pressure washing the entire roof, the crew applies
primer. In this instance the primer is Andek's Polaprime 21.After a full day
to cure, the roof is inspected for breaks and other imperfections.This
Polaprime 21 exhibits two other advantages besides retarding rust: acrylic
adheres better and the metal is reinforced. There is a difference felt as
one walks the roof.
On this roof, more than 40 breaks in the panel surface
were repaired. Vertical seaming consists of a base coat of Andek's Polaroof
AC, then mesh embedded into the base coat, contouring the mesh (a stitchbond
polyester) to the roof profile. The mesh then receives another coat
After the vertical seams, the horizontal seams are next.
This seaming follows the contour of the metal panel. Mesh needs to be
applied loose to adjust to the curing acrylic, yet stretched enough to avoid
Two acrylic coatings are applied to the roof. In most
cases, the coatings are applied by brush, not sprayed. It is true that the
sprayed acrylic goes down faster, but our experience has taught us that
spraying invites customer concern. The concern is that the building owner's
customers--such as plane owners--express considerable concern about
overspray. So we brush.
The top coat is a newly formulated acrylic designed to
maintain the white luster longer. Andek calls this version "XTRA
WHITE".Amazingly, this version of white acrylic is cool to the touch, even
on 90+ days.
