Metal Roof Panels

Use this CSI 3-part SimpleSpecs™ master specification to specify preformed metal roof panels, underlayment, and trim.


Custom metal roofing is specified in SimpleSpecs™ Section 07 61 00 – Sheet Metal Roofing.


Metal Options

This section includes panels formed from aluminum, galvanized steel, pre-coated galvanized steel, and aluminum-zinc alloy coated steel.


Roofing is installed over solid sheathing and an underlayment rather than spaced sheathing or framing.  It is nearly impossible to make sheet metal roofing absolutely watertight due to its high coefficient of thermal expansion.


Metal panels are available from various manufacturers with a wide range of profiles.  The profiles range from interlocking edges where the panels interlock to fasten, while others have simple lapped edges where the panels are face fastened.


What is oil canning?

Roofing is susceptible to waviness in the metal as the metal expands and contracts, referred to as oil canning. Oil canning is primarily an aesthetic issue and is worse on wide, flat surfaces. Placing intermediate ribs between the primary ribs minimizes oil canning, as does detailing the roofing to allow for expansion and contraction. In no case should the roofing be fastened in a manner that prevents movement. Increasing the gage of the metal has little effect on oil canning.  Consult a manufacturers technical personnel for recommendations to minimize oil canning.


Thermally responsive panel clips allow for thermal movement and help to minimize oil canning.  As a general rule the wider the panel the higher the probability of oil canning. Intermediate ribs serve to stiffen the panels to minimize oil canning.



Metal roof panels are installed over solid sheathing and an underlayment where water and air infiltration are of concern, or fabricated to span between framing members, as in canopies.

The SimpleSpecs™ master specs concept
Adding More Words Does Not Make Specifications More Enforceable.    
Design professionals are accustomed to seeing lengthy project specifications, so why is SimpleSpecs™ so short?
Specifications have grown evermore wordy over the years for several reasons:
  1. The mistaken belief that specifications must be lengthy and legal-sounding to be enforceable.  In fact, quite the opposite is true.  Having shorter, easily understood specifications makes us less likely to have problems in the field.
  2. A belief that having lots of words protects us from a Contactor making mistakes.  There is no way to include enough statements to protect yourself from a bad contractor, regardless of the length of your specification.
  3. Our desire to be in control of the project by specifying means and methods instead of including simple, enforceable statements.
Easier to Edit

SimpleSpecs™ is written as a series of Microsoft word files that include statements that affect construction costs or overall quality and are far simpler to edit than other master specification systems.


Each SimpleSpecs™ specification section is non-proprietary and includes three manufacturers that meet the specified reference standards, descriptive, or performance-based requirements. They are written to allow any listed manufacturers to provide the specified products.

Hidden Guide Text

Each SimpleSpecs™ specification section includes hidden text to inform and guide users in editing the specifications to suit project conditions.

Streamlined Editing

SimpleSpecs™ sections are edited using pre-defined options that are contained in [brackets] or by selecting optional text separated by "OR" statements. Paragraph and page numbering are included as automatic codes, eliminating the need to renumber when revisions are made manually.  Global changes to headers, footer, terms, font colors and phrases are easily updated using a third-party search and replace software, available through ZeroDocs.com.
