There are 3 main Installation Systems for installing a Metstar roof.
The system that an installer will use can depend on the pre-existing condition of the roof, and on the profile that is being installed.
All three systems can be installed right over most existing roofs without the extra expense of tear off and landfill waste.
Here is a short video highlighting Systems 1, 2, and 3
This is the most complicated of the three systems, requires battens also called strapping, usually wood 2x2's. It is so solid is can be installed over open raters. With counter strapping this system combines lightweight strength and incredible ventilation. It is also an wasy and effective solution to straighten out existing roofs that have waved decks. System 1 should be installed by an experienced metal roofer.
SYSTEM 1 MANUAL
Same consept as System 1 except the field area is installed using a Build-in Batten thus eliminating horizontal batten strapping. This is a simplification of the same panel used in System 1 but with a batten built into the panel. This system can only be installed on a solid deck not open rafters, most roofs in North America have a solid deck anyway. This makes the installation easier by not having to deal with the carpentry involved in System 1 and still gives you most of the strength, beauty, and durability especially if no extra ventilation or structural repair is required. System 2 panels can also be installed with the same roofers preferred local metal flashings used in System 3. System 2 should be installed by a professional roofer with some experience in metal roofing.
SYSTEM 2 MANUAL
DIRECT TO DECK
Same as System 2 except this is a hidden fastener system that can be combined with innovative flashing designs that are adaptable to each roofing contractor's preferred individual installation method. This system is easiest because it eliminates the need for bending or special tools and installs just as easily as siding. System 3 should be installed by a professional roofer.
