Yes, gutters (eave troughs) can be used with steel roofs. In most cases, our advice is to use a heavy duty gutter such as a 6” K-Style gutter produced from .032” aluminum. Additionally, we advise hanging the gutters as high as possible, with appropriate pitch for drainage. In order to avoid interference with the roof system, gutters should be installed using fascia-mounted brackets. If necessary, the roof system drip edge can be notched to allow for the brackets. The drip edge should always direct water into the gutter. Many of the gutter protection and cover systems can also be used with metal roofs though our preference is for leaf control systems that sit inside of the gutter and, again, do not interfere with the roof system.
