Is it ok to install the metal roof on top of the existing asphalt shingles or should they be removed first?

    Depending on the amount of layers and building codes in your area it may not be necessary to remove the existing shingles. It is ok to put a metal roof over existing roofs, it adds extra insulation. Just be sure to check the building codes in your area.

    You should check with a professional. Even if codes permit, your structure would have to be able to bear the additional weight, particularly if the current shingles were laid over a previous shingle layer.

    Something to consider..... in event of a fire, a metal roof makes it nearly impossible to put the fire out. Most fire departments just let it burn until the tin roof collapses onto the foundation. They pour water on it so that it doesn't spread to other houses but everything inside the house is a complete write off.

    My husband said depending on layers You can put down wood strips or take it off you can't go down on shingles because of the heating and cooling effects Will cut a holes in the metal roof . He's a retired roofer.

    FYI, your cell phone and internet may be worthless with a metal roof. Wish someone had told us before we bought a house with metal roof on house and garage. Picture everyone wandering around 4 acres trying to get bars on heir cell phone.

    I had metal roof, shingles removed. Two houses down shingles also removed. I'm in Fl.

    In some states you cannot have more than four layers of roofing on your house, the recommendation for a metal roof is to leave existing roof on if you don't have to many layers, if you have the the limit allowed in your state then 0ne or two layers will have to come off. The obvious advantage to leaving existing roof on is heating and cooling, but also you increase your chance of never getting a leaky roof.
    There are a lot of roofers out there that claim they know how to put a metal roof on when they don't and you can end up with a lot of problems, so do your homework on the roofers in your area.
