What a real replacement includes
A proper replacement is not just new shingles. The old roof comes off down to the wood deck, the crew replaces any decking that is soft, split, or water-stained, and then goes back with new underlayment, new flashing around every chimney and vent and valley, drip edge along the edges, and the new roof surface on top. If a quote is priced to lay new shingles over the old ones, that is a shortcut called a roof-over, and while it is cheaper today it hides whatever is rotting underneath and rarely lasts.
How to tell replacement beats another repair
One leak is a repair. But when you are patching the same roof every storm season, when shingles are curling or losing their granules across the whole roof, or when a roofer pulls up a shingle and the decking underneath is dark and soft, you are past the point where more patches pay off. A good honest roofer will tell you when a repair is the smarter money and when you are just renting time on a roof that needs to come off.
Materials that actually hold up on this coast
Salt air, hard sun, and hurricane wind are the three things that kill roofs here, and not every material handles all three. Architectural asphalt shingles are the common choice and, in a good wind-rated version, do fine. Metal lasts the longest and sheds wind and salt the best, for a higher price up front. Whatever the material, the wind rating and the quality of the install matter more than the brand name, because most roofs that fail in a storm fail at the edges and the fasteners, not in the middle of the field.
What slows a job down
Weather is the obvious one, since nobody should be tearing off a roof with rain in the forecast. The other is hidden damage: once the old roof is off, the crew sometimes finds decking that has to be replaced, which adds a little cost and a little time but is far better caught now than sealed back up. A roofer who warns you about that possibility up front is being honest, not padding the bill.
- A tear-off to the bare deck lets the crew find and replace soft or rotted wood before it is hidden again
- Wind rating matters more here than almost anywhere, so ask what the system is rated for
- A written workmanship warranty from the roofer, separate from the manufacturer material warranty, is the one to read
Questions people ask about roof replacement
Can new shingles go over the old ones?
It is done, and it is usually the wrong call. A roof-over skips the tear-off, which saves money today and hides whatever the old roof was concealing, soft decking especially. On a coast that tests roofs this hard, paying for the tear-off is paying to know what is under your new roof.
What surprise costs come up mid-replacement?
One, mostly: rotten decking discovered at tear-off. It cannot be seen until the old roof is off, and it must be replaced before the new roof goes down. An honest roofer warns you about the possibility up front and prices the boards in the contract, so the surprise is small and expected instead of a mid-job ambush.
Do I need to be home while the roof is done?
No, and most people are happier elsewhere, because tear-off is loud. Move vehicles out of the driveway, secure pets, and mention anything fragile on walls, since the hammering shakes the house. A good crew finishes with a full cleanup and a magnet sweep for nails.
