A roof replacement in Charleston should be built for wind, salt and humidity from the deck up. We tear off the old roof, inspect and re-nail the decking, install synthetic underlayment with peel-and-stick protection, replace every piece of flashing, and finish with high-wind rated shingles, standing seam metal or a membrane system for low-slope sections.
Choose the right roof for your home
Most Charleston-area homes get architectural shingles, the best value per year of service. Standing seam and 5V metal roofs cost more but last two to three times longer. Flat roof membranes cover piazzas, porches and commercial buildings, and FORTIFIED upgrades add hurricane protection that may lower insurance premiums. Compare them in the 2026 roof replacement cost guide.

Roof replacement questions
How much does a roof replacement cost in Charleston, SC?
A typical 2,000 square foot roof runs roughly $11,000 to $18,000 with architectural shingles and about $24,000 to $40,000 with standing seam metal. Pitch, the number of layers to remove, decking repairs and access all affect the final price. Every estimate is written and free.
How long does a roof replacement take?
Most shingle roofs are replaced in one to three days. Standing seam metal usually takes three to seven days. Weather and permits can add time.
How long does a roof last in Charleston?
Plan on roughly 18 to 25 years for architectural shingles, 15 to 25 years for flat roof membranes, and 40 to 60 years for metal in the Charleston climate. Salt air, humidity and storms shorten lifespans compared to national averages.
What's the best roof for a Charleston home?
For most homes, high-wind rated architectural shingles offer the best value. Standing seam metal costs more but lasts much longer and handles wind well, and aluminum is the better choice near the ocean. Low-slope areas need a membrane like TPO or modified bitumen.
