Things You'll Need
Shingles or panels
Purchase a protective sealant of zinc or aluminum coating to avoid rusting of a metal roof not made of steel. Most of these come with long-term warranties.
Keep your personal safety a top priority. Wear rubber-soled shoes and brace your ladder or use a tie-off one that has non-slip safety steps. If hiring a contractor, make sure the individual or team is licensed and insured. Ask to see documentation of professional qualifications and insurance. Since metal roofing is fairly new, some homebuilders might not have the required experience and can increase the chances for liability.
How to Install Metal Roofing. A metal roof is a good material for your home since it holds up well under dangerous weather conditions, has a top fire safety rating and is waterproof. Many homeowners and roofers are choosing it not only for safety but for durability. You'll have to lay out a substantial amount of money to install this roof, but it's a good long-term investment.

Get the look of a tile or wood roof system by using a shingle. You get a variety of color choices and design patterns with these materials.

Install the metal shingle or panel you have purchased right over your old roof. Check with your manufacturer if this is possible for your home, which in many cases it is.
Attach the starter flashing to prevent leakage. Adhere strips of securing flashing to the roof by nailing it into the fascia trimboard and to the sections of the roof. Apply the counterflashing strips as needed.
