Selecting and installing a standing-seam metal roof
Are there any disadvantages to installing a metal roof over a single layer asphalt roof? The cost savings of removing the old roof and disposal make this option attractive.
Also, does the heavier 24 gauge metal roof have advantages over a 26 gauge roof? I've heard from other contractors that the heavier gauge is harder to work with and the finish cracks more easily.
