Have a question? That said, if you want to have a metal roof that is worth its weight in value, that doesn’t come with a ton of problems, the minimum pitch for metal roof applications should be kept at around at least a 3 1/2:12 (three and a half on 12) or above. Speaking about standing seam metal roof slope, it is a general and a self-evident knowledge that the steeper it is, the faster it is for snow, rain or drain to come down the roof.
The metal roof minimum slope doesn’t stray far from other building with different material. Concrete Tile, Barrel, Mission or Two-Piece, Concrete Tile, Barrel, Spanish or S-Shaped, Metal: Metal Roof Panels, Non-soldered, No Lap Sealant, Metal: Metal Roof Panels, With Lap Sealant, Metal: Metal Roof Tiles (Metal Roof Shingles, Interlocking), Metal: Stone-Coated Steel (Metal Roof Shingles, Interlocking), Synthetic (Composite, Plastic) Shingles/Slates/Tiles.
Click Here! The cant strip shown is wood fastened by copper straps, spaced 2'-0" apart, soldered to the copper flashing. This is particularly important to pay attention to when using metal roofing products, such as standing seam metal, which have a multitude of profiles, attachment methods, and seam/lap/joint styles which can affect the recommended slope. Transverse seams should be based on the "low pitch" option. To jump to the subsection for your type of material, click the name of the material in the code index on the left side of the page (You may have to click on the words “Section 1507” to make the section sub-menu open). The optional cleat shown can be used to hold the roofing pans during installation. In this detail the steeper pitched roof is above the one of lower pitch. According to the 2012 International Building Code (1507.4.2 Deck slope), minimum slopes for roof panels need to comply with the following: 1.
Building codes are perhaps the most important driving force dictating the roof slope to choose.
This detail shows a shallower pitched roof joining a steeper pitched roof below. This link will take you to Section 1507 Requirements for Roof Coverings. Change of Roof Slope - Wood Cant.
The ends of each sheet should lap over the preceding one at least 4". Alternately, cleats at 12" O.C. The values given here (except for thatch) are taken from the model International Building Code, although you should always check with your local code authority in case there are local amendments to the code that affect required minimum roof slopes. Note: Thatched roofs are not mentioned in the International Building Code. Special Roofing Design and Installation Considerations, Where ice, snow, and heavy rain do not occur, Neither sealant nor solder is required in seams.
It appears the industry standard minimum pitch for standing seams is 1/4:12 or 1/2:12, depending on which resource you consult. Find the answers to your questions about roofs and roofing. Architecural Manufacturers & Distributors, Architectural Installation Contractors Database, UNS Standard Designation for Wrought and Cast Copper, ASTM Standard Designation for Wrought and Cast Copper and Copper Alloys, European Numbering System for Non-Ferrous Metals, Copper - The World's Most Reusable Resource, Safe Drinking Water Act and Copper Alloys, Toxicological Differences in Lead and Copper, Lead-free Solders for Drinking Water Plumbing Systems, 8.1. Steeper roofs shed water and snow faster and are less likely to have debris accumulate on the roof. The conditions are representative of typical installations. Only flat seam roofing is constructed to be completely watertight, and therefore can sustain standing water. Table 8.1A shows the recommended minimum slopes for various copper roofing systems using the details shown throughout this Handbook. The wood cant is nailed to the sheathing. This detail shows an alternate cant. Table 8.1B shows the minimum recommended slopes using these special details.
It also has a built-in, formed gravel stop. 1. The minimum pitch is typically 3:12, meaning the roof should rise 3 inches for every 12 inches of horizontal foot.
They lap over the lower roof and are lapped by the upper roof. The lap of the upstanding legs of the pans should also be set in sealant. Lower slopes are possible under certain conditions, using modified details.
The recommended minimum thickness of copper is 16 oz. It laps the lower roofing a minimum of 4".
The standard of lower pitch actually ranges between 1:12 to 5:12. The other is $13,786 for 20 oz.
This detail shows a shallower pitched roof joining a steeper pitched roof below. This is particularly helpful on a steep roof.
Roof Slope Equivalents (as rise : run, in degrees, and as percentage) The minimum roof slope allowed by code for any type of roof is ⅛-in-12, applicable only to coal tar pitch roof systems.
Movement can occur as a result of internal stresses due to temperature changes, or from external sources such as wind, ice, or movement in the substrate.
Mansard roofs are usually steep, but they often have changes in their slope.
A cant of some kind is used to raise the roofing material and keep it from direct contact with the copper surface, to minimize line corrosion.

For each type of roofing material, you can see the actual language used in the model 2018 International Building Code at the International Code Council website. 2.
If you need help figuring out the slope or pitch of your roof, we recommend this slope finder on Amazon. Providing an effective path for water to flow in a controlled direction is one of the most important principles in design and construction. Different types of roofs have distinct specifications for installation. It’s important to bridge the individual shingles to get an accurate reading. The lower edge of the flashing is hemmed and cleated to the sheathing at 12" O.C. Description: Flashing a change in roof slope usually involves copper sheets 8 or 10 feet in length. There are many combinations of roofing materials and corresponding numbers of appropriate details for each condition. Lapped, nonsoldered-seam metal roofs without applied lap sealant must have a minimum roof slope of 3:12 (25% slope). About • Contact • *Disclosure Statement • Legal Statement • Privacy Policy. * It’s very inexpensive and very accurate. You can often see such examples of use over metal decks. As an alternate, a lock clip can be used as shown in Detail 9.6D. The details shown are valid for shingle, tile, and slate roofing. See Detail 8.2C.
