SAFETY AND STORAGE CONSIDERATIONS As with all major construction projects, safety should be a primary concern. The erector or contractor should be sure that all OSHA safety rules are followed and that job safety is strictly adhered to. The following safety equipment is highly recommended when installing metal roofing: 1. Safety rope and harness 2. Hand protection 3. Eye protection CAUTION Care should be taken when cutting sheets. Eye and hearing protection are important.
CARE AND HANDLING OF MUELLER SHEET METAL Delivery: Mueller takes every precaution to ensure that material is delivered to the customer damage-free and fully protected from the elements during shipment. When the material is delivered to the customer it then becomes the customer’s responsibility to protect the material from the elements, possible theft, and other damage.
INSULATION Insulation Installation: When insulation is installed, the outside edge of the insulation should be tight against the outside edge of the rake angle. A starter role of 4’ or 5’ is normally used so that approximately 12” of the leading edge will still be exposed when a new run of insulation is installed. This allows easy access to the vapor barrier lapping of the insulation.
