Yes, you can use metal roofing for low-pitched roofing. In fact, many contractors recommend that asphalt shingle roofs go no lower than 4:12 slopes, which doesn’t leave you with too many options if your roof slope is any shallower than that. Luckily, metal roof works extremely well in low slope applications.
Can metal roofing be used on a low slope/pitch roof?
The traditional metal roof types, such as 5V-crimp (shown above) and corrugated, are rated by the manufacturers for use down to a 3/12 pitch —three inches of vertical “rise” for every foot of horizontal “run.”.
While I was reading we ran into the question “Can I use metal roofing on a flat roof?”.
Yes, you can put metal on your flat roof. Installing a metal roof over a flat roof area, over a porch, or for other accent purposes is considered an upgrade. With that in mind, it’s actually fairly common for homeowners to put a metal roof over their flat roof or low slope roof.
What are the pros and cons of metal roofing?
Metal roofing typically comes in large sheets, but you can order smaller sizes to fit around unique features or irregular extensions of your roof—for example, small patios or covered stairwells. As with most things, there are some downsides to metal roofs. When it comes time to replace a metal roof, they generally have to be torn out completely.
What do you need to know about low sloped roofing?
Low slope roofs also tend to require less material, so even if you go for a pricier roofing material, your cost will still be lower because you’ll need less material for the job. But most low slope roofs use a material that can be rolled and sealed, which is infinitely easier to do on a flatter roof.

What is the lowest roof pitch for metal roofing?
The minimum pitch for metal roof shingles and lapped, non-soldered panels is 3:12. After that, the minimum pitch for metal panels depending on the methods used to join the panels. Panels joined with an applied lap sealant can go as low as :12.
One of the next things we wondered was what is the minimum pitch of a metal roof?
To get the minimum pitch for a metal roof, the vertical rise per foot is divided by the horizontal slope. Most metal roofs will have minimum pitches of three in twelve, but this might sometimes go down depending on whether there are special installation procedures issued by the manufacturer regarding that particular roofing material.
One more query we ran across in our research was “What is the minimum pitch for a steel roof?”.
The metal roof minimum slope doesn’t stray far from other buildings with different materials. The minimum pitch is typically 3:12, meaning the roof should rise 3 inches for every 12 inches of the horizontal foot. The standard of lower pitch actually ranges between 1:12 to 5:12.
What is the best roofing material for a low pitch roof?
TPO. A relative newcomer to roofing, Thermoplastic Polyolefin (TPO) is a single-ply membrane with many excellent qualities. Before there was TPO, Polyvinyl Chloride (PVC) reigned in the single-ply roofing market. A couple more things to keep in mind: modified bitumen, epdm, and built-up roofing.
Metal Flat Roofing Metal is one of the most popular materials used for flat roof replacement. Metal, specifically aluminum, is known for its durability. Flat metal roofs can last for almost 35 years in ideal conditions.
