Special considerations must be taken when building in coastal regions. This is especially true on coastlines where hurricanes are a yearly threat. Using proper construction techniques and materials can ensure long-lasting structures that hold up against the harsh weather conditions common in many coastal locations.

Planning to Build

Building in a coastal climate isn’t much different than building anywhere else, but there are some considerations to keep in mind.

Foundations: Your foundation will require extra support if you will be living very close to the ocean, especially if your building may have to withstand hurricane-strength winds. Reinforced concrete is a popular choice. Some foundations may also have to be lifted away from flood zones, utilizing stilts or columns.

Materials: You will want to find materials that are designed to withstand not only water saturation but also resist corrosion caused by exposure to salt spray and high-level winds in a storm zone.

Location: Make sure you have your lot assessed for flood and erosion risk. It’s important to purchase land that has stable soil and is sufficiently elevated away from potential flood zones.

Choosing Building Materials for Coastal Builds

Once you have a general plan in place for your building project, it’s time to select the materials you’ll use. Your main priorities will be choosing products designed to prevent corrosion and withstand heavy winds, especially in hurricane zones or areas where your home may be exposed to high winds.

Ideally, you’ll be working with a knowledgeable contractor who can walk you through various building materials. A few to keep in mind include:

Framing and Foundation

Concrete is the winner for stability when it comes to foundations. It is also a suitable material for constructing the walls of your home. Wood framing is also a popular choice, although it may be a good idea to go with marine-grade lumber if you are very close to the saltwater.

Siding

Some siding materials won’t hold up well in coastal conditions. Wood siding, for instance, can rot or require frequent repainting. Cedar shingle siding is one exception, as it holds up better than other wood varieties and isn’t commonly painted. Cement, vinyl, and fiberglass are also durable and corrosion-resistant options.

Roofing

Cement and terra cotta roofing materials hold up well in coastal regions, as they are both resistant to water and corrosion. Some metal roofing, such as aluminum, is also a good choice.

Insulation

Conventional insulation can be prone to mold and mildew in high-moisture regions. Closed-cell foam insulation doesn’t have these issues while still providing the energy efficiency and climate control you need to maintain comfort.

Hardware

Deck fasteners, framing nails, and other hardware should be made from materials such as stainless steel to prevent rusting and corrosion over time.

Windows

If you live in an area at risk for high winds or hurricanes, you will need impact-resistant windows. They are made from specialized glass that prevents shattering during storms.

Other Considerations

Although choosing materials for your project is important from a durability standpoint, it’s important not to discount other factors you may find important as well. Here are a few other considerations you should keep in mind when making a decision:

Budget

In general, longer-lasting materials cost more up front. Modern builders have more options than ever before, so your budget-friendly options that won’t sacrifice longevity are less limited than in previous decades. That said, you should still aim for the highest quality product you can afford to get more for your money over the long haul.

Aesthetics

Many coastal regions have a certain aesthetic appeal you may want to replicate. This may require you to choose certain materials over others. You may also have a specific look in mind for your home that will require finding alternative materials with a similar appearance.

For instance, some wood siding materials aren’t suitable for a coastal environment, but newer composite siding can replicate the appearance of real wood with greater weather resistance.

Ease of Installation

If you are a DIY’er making repairs or doing a building project on your own, you may want to choose materials based on how easy or quick they are to install. Thankfully, there are modern options that can achieve most any style with much simpler installation methods than older options.

Putting it Together

Choosing materials specially designed to withstand coastal weather is essential to ensuring the longevity and beauty of your construction project. Corrosion- and wind-resistant options will help your home or structure stand strong for decades. Additionally, routine inspections and timely maintenance will help your materials perform at their best, allowing your coastal home to remain secure, efficient, and visually appealing for many years to come.

With the right combination of planning, material selection, and upkeep, your coastal build can deliver long-term comfort and protection in even the harshest conditions.
