A parish permit and a ranch roof
Harvey is not a city. The parish permits it. The roofs are straightforward until the deck is not. A ranch with one layer of architectural shingles is a clearer repair-or-replace decision than a slate roof uptown. We still open the question of soft plywood at the eaves before we price a tear-off.
Katrina replacements are about twenty years old now. That is a reason to look, not a reason to replace every house on the block. Pipe boots and ridge vents usually fail first.
