How to Choose a Metal Roofing Company Near You That Knows Salt Air
Choosing a metal roofing company near you comes down to whether the roofer matches the metal to your exposure, or just sells the panel on the truck. Charleston Roofs and Windows installs aluminum, steel, copper and zinc, so the recommendation follows your house, not our inventory.
"Eric was great and professional without being pushy. They were willing to do repairs on our roof when several other companies were pushing only a new roof option."
Three Questions to Ask Before You Hire a Metal Roofer
Ask every metal roofer these three questions before you sign.
Which Metal Do You Recommend for How Close I Live to Salt Water?
Salt spray eats the wrong metal from the edges in. At least one major panel maker's Galvalume warranty doesn't cover roofs within 1,500 feet of salt water, marine air or salt spray. A roofer who never asks how close you are to the marsh isn't thinking about your warranty.
How Charleston Roofs and Windows Answers
At your free inspection, Charleston Roofs and Windows walks you through metal type, panel style, rib height and coating, and why each one fits your exposure. Waterfront homes usually point to aluminum. Inland homes have more room for coated steel.
Is This Standing Seam With Concealed Clips or Screw-Down Panels?
Two quotes can both say "metal roof" and land thousands of dollars apart because one is standing seam and the other is screw-down. Make the roofer name the system in writing.
How Charleston Roofs and Windows Answers
We install both systems, and your written estimate from Charleston Roofs and Windows names the panel system, the metal and the finish. No guessing what you're paying for.
Who Supervises the Crew and Walks the Roof With Me?
Metal is less forgiving than shingles. A bent seam or a sloppy flashing cut shows up as a leak or rust streak years later.
How Charleston Roofs and Windows Answers
Every metal roof is overseen by a W2 project manager employed by Charleston Roofs and Windows. He checks the work as it goes in and does a final walkaround with you at completion.
● W2 Project Managers on Every Roof
Project managers like Jared Purcell are employees, not subcontractors, and they carry your job from material delivery to final cleanup.
● BBB A+ Accredited and HomeAdvisor Approved
Charleston Roofs and Windows has held a BBB A+ rating as an accredited business since February 2024 and is HomeAdvisor approved.
Red Flags on a Metal Roof Quote
You can't compare a screw-down price to a standing seam price.
That choice drives the metal, the fasteners and the warranty.
Mixed metals corrode each other.
Exposed fasteners need checking for life.
Standing Seam vs. Exposed Fastener Metal Roofing: Which System Belongs on Your Roof
Standing seam metal roofing is a system of vertical panels joined by raised seams and held down with hidden clips, while exposed fastener roofing screws the panels straight through the face into the roof deck.
Charleston Roofs and Windows installs both, and the right pick depends on the building, the budget and how long you plan to stay.
- How it attaches Concealed clips under the seam
- Thermal movement Panels slide on clips as they heat and cool
- Upkeep Check penetrations and clear debris
- Wind performance Many systems rated in the 140 to 180 mph range
- Typical SC installed cost (steel, 2026) About $10.65 to $13.30 per sq ft
- Best for Homes, coastal exposure, long-term owners
- How it attaches Screws through the panel face
- Thermal movement Panels pull on the screws, which can wallow out the washers
- Upkeep Check and replace screws or washers, often every 5 to 15 years
- Wind performance Lower, and depends on screw condition
- Typical SC installed cost (steel, 2026) About $6.90 to $8.60 per sq ft
- Best for Porches, sheds, barns, workshops, budget projects
Why Standing Seam Is the Coastal Favorite
There are no screw holes in the field of a standing seam roof. The clips let each panel expand and contract through a blazing afternoon and a cool night without tearing at the fasteners. Fewer holes means fewer places for wind-driven rain to find.
Snap-Lock vs. Mechanical Seam
Snap-lock panels click together along the seam and install faster. Mechanical seam panels are crimped shut with a seaming tool for a tighter lock, the better choice for hurricane exposure and lower roof pitches.
Rib Height and Panel Width
Residential standing seam ribs typically run 1 to 1.5 inches tall, with commercial panels at 1.5 to 2 inches. Taller ribs add stiffness and move heavy rain better. Lower ribs give a cleaner, more streamlined look on a house.
Where Exposed Fastener Panels Make Sense
Screw-down panels cost noticeably less and go on fast. Charleston Roofs and Windows recommends them where budget matters more than a 50-year horizon:
- Detached garages, sheds and workshops where a lower price per square foot wins.
- Barns and agricultural buildings on rural and farm property.
- Covered porches and carports that need a quick, durable cover.
- Rental or short-hold properties where you won't own the roof in 30 years.
"Eric and Grady did a very good job replacing my shingle roof with a metal roof. Things went smooth and quicker than I expected once the work got started. Very professional operation."
Aluminum, Galvalume Steel, Copper or Zinc: Matching the Metal to Lowcountry Salt Air
The best metal for a Lowcountry roof is the one that matches your distance from salt water: aluminum for waterfront and island homes, coated Galvalume steel for most inland homes, and copper or zinc for accent roofs and statement projects. Charleston Roofs and Windows installs all four.
Salt Air Fit Excellent. Resists salt corrosion
Upkeep Very low
Best Use Waterfront, marsh-front and island homes
Salt Air Fit Good inland. Some warranties exclude roofs within 1,500 ft of salt water
Upkeep Low with a quality finish
Best Use Most inland homes and commercial buildings
Salt Air Fit Long-lived, weathers to a protective patina
Upkeep Very low
Best Use Bay windows, porch roofs, dormers, accents
Salt Air Fit Long-lived, forms a natural protective patina
Upkeep Very low
Best Use Architectural accents and custom homes
Coatings That Hold Color in the Sun
A metal panel is only as good as its finish. PVDF finishes, sold under names like Kynar 500, are the industrial-grade paint systems that resist chalking, fading and corrosion. Charleston Roofs and Windows explains the finish options at your inspection so you know what you're getting.
Fasteners, Flashings and Mixed Metals
The panel isn't the only metal on your roof. Near the water, stainless steel fasteners are a common salt-air upgrade, often adding a few hundred dollars to the job. Charleston Roofs and Windows can price it into your estimate when your exposure calls for it.
Keep Copper Away From Aluminum and Steel
Copper runoff speeds up corrosion on aluminum and steel it drains onto. Every connecting metal on the roof, from flashing to gutters, has to be compatible.
Penetrations and Skylights Are Where Metal Roofs Leak
Metal panels rarely fail in the open field. Leaks show up at vent pipes, chimneys and skylights, where the flashing has to be cut and sealed by hand. That's where Charleston Roofs and Windows inspection managers spend their time on an existing metal roof.
"We had a metal roof with serious skylight leaks. Jesse came with his crew and they did a review of the roof as well as the skylights and found that there were several problems that needed to be addressed. He took plenty of pictures so I could see what they were talking about."
