For the most part, there are two types of roofs: pitched and flat. Used mostly for industrial, commercial, or manufacturing facilities, flat roofing choices aren’t as plentiful as pitched roofs. Made mostly of bitumen, rubber membranes, or even tar, these roofs have a very slight slope to ensure the water drains away.

There can’t be any spaces, seams, cracks, etc. or else water will find a way through. Ponding is a huge issue, although some flat roofs drain to the middle of the roof to a drain system. There are some residential flat roofs, but slope roofing is much more common.

With pitched roofs, taking water away from the home is a much easier proposition. The steeper the slope, the easier it is for rainwater and other precipitation to find its way to the gutters. If it isn’t a very steep slope, water may not drain away as well, causing issues.

When choosing a roofing covering, it’s important to know what the slope of your roof is. Although different jurisdictions may have different regulations, even flat roofs must have a general slope of at least ¼ inch rise for every 12 inches. From there, different roof surfaces need different slopes.

Metal roofing systems, such as a standing seam roof or a corrugated metal roof, are ideal for low-slope applications that aren’t “flat” roofs. These metal panels come in large sheets that cover the length of your roof from your ridge to your gutter. This means there are fewer opportunities for water to get under the material.

Another advantage of the standing seam or corrugated roof panels is the rainwater is channeled to equalize the weight of the water on the roof. It also minimizes large ponding, providing more protection for the roofing material. For these panels, the generally approved slope is at least 2 inches per 12 inches. More slope is obviously better, though.

For aluminum shingles, the slope reaches 3 inches for every 12 inches. There are more seams and fasteners with shingles, so it makes sense to have a steeper pitch than with the panels. However, this slope can be minimized if additional sealants or special underlayments are used.

For a little perspective, asphalt or composition shingles need a minimum of four inches of slope per 12 inches. The minimum slope for slate and clay tiles is 4 inches per 12 inches and for slate shingles. These pitches may be lessened with approved underlayments. Please check with the codes and specifications in your area.
