Installing gutter guards on a metal roof requires careful attachment to ensure that the guards fit properly without interfering with the roof's edge. Gutter guards should be mounted to the gutter itself, not under the roof panels, to avoid damaging the metal roof or voiding its warranty.

Metal roofs can expand and contract with temperature changes, so it’s important to install gutter guards that are compatible with metal roofing. Ensure the guards are securely fastened to prevent them from becoming dislodged during extreme weather.
