I live in a 1940, single story, single hip roof, 1100 sq. ft. tabby home in coastal Georgia, but not directly on the water. It is my primary residence. The roof sheathing is solid substrate (decking).I have a few questions about replacing my asphalt shingle roof with a properly installed, Gavalume, metal roof
As far as profiles I was thinking of “R- Panel “or “5V Crimp”. Typical of the older cottages down here, there is a slight waviness or imperfections to the roof. Would an r-panel sheet roofing hide blemishes better than a 5v-crimp? The ribs of an r-panel have 11/4 “ tall ribs and 36” panel coverage and are reportedly good for lower sloped roofs. 36 inch coverage would require fewer holes and screws since most 5v crimp has 16 inch coverage.
Or, would 5v crimp be a better sheet roofing choice?
Can Ice & Water shield be used as underlayment? Can metal roofing be installed directly on the Ice & Water shield?
Is 24 gauge metal roofing less prone to “oil canning” than 26 or 29 gauge roofing?
Stylistically, and given my geographical location, which roof style do you think would be better?
Unfortunately, standing seam roof style is more than my budget can afford.
(By the way, as seen in attached photo, I will be removing the existing skylight.)
Your thoughts would be appreciated,
