Wrap the aluminum strip tight around the underside of the gutter. Whether you ve got metal roofing roll roofing or sloped roofing it s best to hire a professional for consult and install. One of the biggest challenges involved in gutter installation is establishing the proper slope of the guttering. From a distance gutters appear to parallel the roofline.

You want at least a quarter inch of slope for every 10 feet.
