There
are numerous types of metal roof design and material options, ranging
from flat locked copper shingles; to steel Spanish-barrel tile; from
traditional standing or vertical seam; to aluminum and steel products
designed to mimic wood and tile shakes and shingles. Depending upon
the individual product, metal roofs can achieve a vast variety of looks
and can drastically differ in pricing, as well.
Generally, metal roofing products fit into two main categories: structural
or architectural. Structural panels, which are used on low-pitch applications,
are usually installed directly over purlins, effectively becoming both
the deck and the roof. Vertical seam-type panels are the most common
type of structural metal roofing and are almost always used on non-residential
projects. Architectural metal roofing includes all specialty residential
roofing products. Architectural panels are installed over a wood or
metal deck, or in some applications, directly over an existing roof.
ChemTech
Roof & Insulation Systems installs the following types of metal
roof systems:
- Standing
Seam structural panels are used for both residential and non-residential
applications. They can be manufactured in the factory or roll-formed
on the job site. Generally, they are cut to length with raised seams
and secured with concealed fasteners
- Corrugated
panels are a building grade material that is inexpensive. It's fire
protection depends on the quality of installation
- Batten
Seam is also known as “Board and Batten” panel systems.
A continuous vertical clip is fastened to the substrate and clipped
into the panel edges. A metal batten cover is then installed over
the seam
- Flat
Seam is installed on flat, low-slope, very steep or unusually
shaped roofs. The seams are typically locked and soldered
- Bermuda
systems are those in which the joints are horizontal instead of
vertical and are installed from the bottom eave to the ridge
- Metal
Shingles and Shakes are usually made from aluminum, steel, copper
or zinc, specialty metal roof systems are becoming increasingly popular
for residential applications. With superior durability; longevity;
wind and fire resistance; energy efficiency; and beauty; metal shingles
and shake systems outperform and outlast traditional roofing materials
