Protecting Your Home’s Exterior in Charleston’s Coastal Conditions

Coastal weather, salty air, and humid conditions can take a serious toll on home exteriors in Charleston. Baker Home Exteriors brings over 100 years of experience to help Charleston residents protect and restore their homes against harsh coastal elements. Whether it’s a new roof, durable siding, or ongoing maintenance, we know what it takes to keep a Lowcountry home looking beautiful.

In this post, we’ll walk through the specific challenges Charleston homeowners face, the common types of damage we see, the best materials for coastal conditions, and how our team can help you safeguard your investment.

Why Coastal Conditions Are Tough on Homes

Charleston’s environment is a mix of salt air, humidity, sun, and the occasional hurricane, which can all put extra stress on your home.

Salt

Salt is one of the most corrosive elements a home can face. Found in ocean breezes, salt can cling to siding, roofing, and windows. Over time, it can break down protective finishes and rust the metal in gutters, fasteners, and flashing.

Water

High year-round humidity makes Charleston a paradise for mold, mildew, and rot. Porous materials like wood absorb moisture, which can weaken them and cause visible damage.

Sun

Prolonged exposure to the Carolina sun can cause paint to fade, caulk to dry out, and make plastics brittle. Combined with the salt and moisture, it’s a recipe for serious exterior wear and tear.

High Winds and Hurricanes

When hurricanes roll through, high winds can lift shingles, toss debris into siding, and drive water into vulnerable cracks and seams. These storms can reveal or worsen weaknesses in roofing, siding, and drainage systems.

We built a storm center to help homeowners with storm preparedness, damage assessments, and recovery.

Common Types of Exterior Damage in Charleston

Here are some of the most common types of exterior damage our team sees on homes in Charleston:

Roofs

Asphalt shingles can curl, crack, or blow off entirely after big storms. Metal roofing is popular in Charleston, but if it isn’t installed with proper coatings, the salt air can eat away at it over time. Watch our YouTube video on how to spot roof leaks, especially around bay windows and additions.

Siding

In areas with lots of moisture in the air, wood siding can swell, rot, and require frequent repainting. Vinyl siding can also warp under the intense Lowcountry sun, leading to gaps where moisture seeps in.

Windows and Doors

Salt and moisture can corrode the metal hardware on doors and windows and damage weather seals. Wooden frames may swell, making windows and doors difficult to open or close, while damaged seals allow drafts and water leaks.

Gutters and Drainage Systems

Gutters are especially vulnerable to rust in Charleston’s environment. Big storms can blow debris into gutters, leading to clogs that cause water backup and rot.

Left unchecked, these issues don’t just hurt curb appeal; they can threaten your home’s structural integrity and long-term value.

Best Materials for Coastal Homes

The good news is there are specific building materials designed to withstand coastal conditions like Charleston’s. We work with top manufacturers to install products built to handle the challenges of coastal life.

Roofing Solutions

Aluminum and Galvalume roofs resist salt corrosion better than steel. With proper finishes, they can last for decades near the water.

Brands like GAF and CertainTeed offer high-performance asphalt shingles rated for high winds and algae resistance, making them perfect for the Lowcountry climate.

Siding Solutions

James Hardie fiber cement siding is a go-to choice in Charleston. It’s made to resist rot, termites, and warping, and it can hold paint longer than wood siding. Plus, Baker Home Solutions is an Elite Preferred Contractor for James Hardie products.

Premium vinyl siding is designed with UV inhibitors, which can help prevent warping and fading under intense sunlight.

Windows and Doors

Impact-rated windows stand up to hurricane-force winds and flying debris while also making your home more energy efficient.

And unlike wood, fiberglass doesn’t swell, rot, or corrode, making fiberglass doors a great choice for humid, salty conditions.

Metal Hardware and Fasteners

Stainless steel or coated fasteners that are rust-resistant can help prolong the life of siding and roofing. 

Protective Coatings and Finishes

There are a number of sealants and paints made for humid, salty climates that can add another layer of defense to the outside of your home.

By choosing the right materials, Charleston homeowners can dramatically reduce long-term repair costs and feel more secure when the next storm comes.

Maintenance Tips for Charleston Homeowners

Even the best materials need regular maintenance to stay in top condition. In addition to the routine maintenance our team recommends for every home, Charleston homeowners should also consider:

• Annual Roof Inspections: At least once a year, and after major storms, it’s important to have your roof inspected by a professional to catch small problems before they become big ones. Watch our video on the importance of preventing water damage where your roof and walls meet.
  
• Power Washing: Whether you do it yourself or hire a pro, a power washer can rinse off salt, mildew, and dirt that collect on siding and trim. You can also use a regular water hose to rinse off salt and dirt if you are worried about damaging siding with a power washer.
  
• Reseal Caulking: You should check your windows, doors, and joints for cracks where moisture could sneak in. If you spot any problem spots, reseal them with new caulk. This is a low-cost job that can save you from expensive repairs.
  
• Gutter Cleaning: Keep your gutters clean and free from debris to prevent water backup and roof rot. Make sure to check your gutters after heavy rains or storms.
