Metal shingles operate much like asphalt ones. The interlocking tabs must be carefully removed so as not to remove any of the undamaged pieces, leaving them in place for when you're done working on your roof! We'll also look at finding loose or broken nails and screws before applying a sealant that protects against water damage from stormy weather conditions - all while ensuring our customers get their homes protected without an expensive repair job later down the line.
