What a reroof costs on the Grand Strand
Coastal roofs cost more than inland ones for reasons that are mostly invisible once the job is finished, and that is exactly why bids here need reading carefully.
Two houses, the same size, the same shingle. One in Conway, one four blocks from the ocean in Myrtle Beach. The coastal one will be quoted higher, and if it is not, that is a reason to ask questions rather than to celebrate.
Typical ranges
Straightforward single storey home, full tear off, architectural asphalt, coastal fastening. Bands local companies tend to quote. Not a quote.
| Roof size | Inland, Conway and Loris | Coastal, within a few miles of the water |
|---|---|---|
| 15 to 18 squares | $9,000 to $13,500 | $10,500 to $16,000 |
| 18 to 24 squares | $11,000 to $17,000 | $13,000 to $20,500 |
| 24 to 32 squares | $15,000 to $23,000 | $17,500 to $27,000 |
| Two storey or steep | add 15 to 30 percent | add 15 to 30 percent |
A square is 100 square feet of roof surface, which is always more than the floor area beneath it.
Where the coastal premium actually goes
Fastening. Design wind speeds near the coast are higher, and the fastening schedule reflects it: more nails per shingle, enhanced edge detail, and attention to the starter course and rake that an inland job may treat casually. That is labour and it is the most important money on the job.
Metal that survives salt. Drip edge, flashing, vents and fasteners in a marine environment want corrosion resistant specification. Standard galvanised near the ocean is a false economy measured in years, and it is exactly the sort of substitution that is invisible on completion.
Underlayment. Coastal jobs more often specify a full synthetic or a sealed system rather than felt, which matters when wind drives water sideways under shingles that are doing their best.
Disposal and access. Tighter lots, restricted parking in the beach communities, and higher haulage costs.
If insurance is paying
Roof age drives premiums here and it drives claim outcomes too. Two questions are worth answering before you file rather than after: whether your policy settles at replacement cost or actual cash value, and what your wind and hail deductible actually is, since coastal policies frequently use a percentage rather than a flat sum.
Keep every photograph and every receipt, including temporary repairs. And do not let anybody talk you into starting permanent work before the loss is documented.
Comparing bids
Take the most detailed bid you receive, reduce it to line items, and ask the others to price that exact scope. Most of the spread disappears. What remains is a genuine disagreement about the roof, and that is the conversation worth having.
Specifically check: fastening schedule, corrosion specification on all metal, underlayment type, new versus reused boots and flashing, ventilation, per sheet decking price, permit, and the two warranty lengths stated separately.
Money questions
- Why is a quote here higher than one my cousin got upstate?
Three legitimate reasons. Coastal wind requirements mean more fasteners and different edge detailing. Corrosion resistant flashing and fasteners cost more than standard. And disposal, access and insurance all run higher near the coast. A gap of fifteen to twenty five percent against an inland quote is normal rather than suspicious.
- Will a new roof lower my insurance?
Often, sometimes substantially, and it depends entirely on your carrier and on what is documented. Roof age alone moves premiums in coastal South Carolina. Documented wind mitigation features can move them further. Ask your agent what they credit before the roof is specified.
- Is metal worth it this close to the ocean?
It can be excellent and the alloy and coating matter enormously. Some metals that perform well inland corrode quickly in salt air. If you are considering metal near the water, the specification is not a detail you can leave to preference.
- Can I just repair the damaged side?
Sometimes. Where it gets complicated is matching, since a shingle weathered by salt and sun for a decade will not match a new one, and whether your policy owes you a full replacement for that reason depends on its wording.
