RESIDENTIAL DESIGN GUIDE
SAFETY
STUDY APPLICABLE OSHA AND OTHER SAFETY REQUIREMENTS BEFORE
FOLLOWING THESE INSTRUCTIONS.
The installation of metal roof systems is a dangerous procedure and should be supervised by
trained knowledgeable erectors. USE EXTREME CARE WHILE INSTALLING ROOF PANELS.
It is not possible for Metal Sales to be aware of all the possible job site situations that could
cause an unsafe condition to exist. The erector of the roof system is responsible for reading
these instructions and determining the safest way to install the roof system.
These instructions are provided only as a guide to show a knowledgeable, trained erector
the correct relationship of parts to one another. If following any of the installation steps would
endanger a worker, the erector should stop work and decide upon a corrective action.
Provide required safety railing, netting, or safety lines for crew members working on
the roof.
Do not use the roof panel as a walking platform. The roof panels will not withstand the weight of
a person standing at the edge of the panel.
Do not stand on any roof panels until the panels have been attached.
The application and detail drawings in this manual are strictly for illustration purposes and may not be applicable to
all building designs or product installations. All projects should conform to applicable building codes for that particular
area. It is recommended to follow all building regulations and standard industry practices.
Metal Sales Manufacturing Corporation is not responsible for the performance of the roof system if it is not installed
in accordance with the suggested instructions referenced in this manual. If there is a conflict between this manual
and the actual erection drawings, the erection drawings are to take precedence.
Prior to ordering and installing materials, all dimensions should be verified by field measurements.
Metal Sales reserves the right to modify, without notice, any details, recommendations or suggestions. Any questions
you may have regarding proper installation of these Residential roofing systems should be directed to your local
Metal Sales representative, (see pages 2 and 3).
Oil canning is not a cause for rejection. Oil canning can be described as the amount of waviness found in the flat
areas of metal panels. Oil canning is an inherent characteristic of light gauge cold formed metal products, particularly
those with broad flat areas. There are many factors which may contribute to oil canning that Metal Sales is not able
to control. These factors include: misalignment of the support system, over driving of fasteners used on the panels,
stress (whether inherent in the panel or induced), thermal expansion and contraction of the panel, improper material
handling, width, gauge, length, color of panels, and improper installation (reference Metal Construction Association
"Oil Canning Position Paper"- Appendix A).
Consult your local Metal Sales Branch for any additional information not outlined in this manual.
This manual is designed to be utilized as a guide when installing a Residential roofing system. It is the responsibility
of the erector to ensure the safe installation of this product system.
