As tin roofs age rust starts to appear, which causes the sheets to erode and develop pin holes. Also sheets become loose and need to be secured. If this is not rectified water damage to ceilings can occur.
At Rainbow Roof Restorations we secure loose sheets with tek screws, treat the rust, high pressure water clean the roof and apply a primer and 2 coats of acrylic roof coating.
This is an alternative to the costly expense of re-roofing.
