Plastic/perspex roof extention

Hi team, I need more of a roof overhang on one side of my terraced townhouse to kind of guarantee it doesn't become a leaky building. My next door neighbour has a clear plastic/perspex overhang specifically for this kind of purpose. There's a special name for it but I don't know what it is, haha. So basically, could someone quote me for installing such an overhang please. It would be mounted on what looks like a pergola that's part of the building structure so the candidate must have understanding and experience of keeping things weathertight. Thanks, Ian
