When it comes to choosing siding materials for your home in Atlanta, composite siding is often seen as a reliable, low-maintenance option. However, despite its many advantages, composite siding may not always be the best choice for homeowners in Georgia's unique climate. At Nelson Exteriors, we've seen firsthand how this popular material can fail in the hot, humid, and unpredictable weather of Atlanta. In this blog, we'll break down the reasons why composite siding may not hold up as well in our region and what alternatives can provide better durability and long-term value.
Understanding Composite Siding
Composite siding, also known as engineered wood siding, is a manufactured material made from wood fibers, resins, plastics, or other synthetic substances. Brands like LP, GP, and Masonite have produced this type of siding for years, marketing it as a durable, low-maintenance alternative to traditional wood siding. It's designed to resist decay, pests, and moisture while mimicking the look of real wood.
However, composite siding has a long history of failing—especially in regions like Atlanta, where extreme weather conditions put it to the test. Despite its initial appeal, homeowners often find themselves dealing with widespread damage that requires full-section replacements rather than minor repairs.
How Atlanta's Weather Wreaks Havoc on Composite Siding
Atlanta's climate presents several challenges for composite siding, including:
- High Humidity & Moisture Exposure
Atlanta's humid subtropical climate is especially harsh on composite siding. The constant moisture in the air can cause swelling, warping, and even mold growth over time. Since many composite siding products are made with scrap wood materials, they are more susceptible to absorbing moisture, leading to rot and decay.

With scorching summers and cooler winters, composite siding in Atlanta expands and contracts frequently. This repeated movement can cause cracking, buckling, and a weakened structure. Prolonged exposure to direct sunlight can also lead to fading and discoloration. - Heavy Rainfall & Water Infiltration
Atlanta sees over 50 inches of rain annually, and composite siding often struggles to hold up against this level of exposure. If not properly sealed and maintained, moisture can seep into the material, leading to further deterioration and mold growth beneath the surface.
The Biggest Problem: You Can't Just Replace a Few Boards
One of the biggest frustrations homeowners face with composite siding is that you can't simply replace a few damaged boards without creating a domino effect. Since composite siding is designed to interlock, removing one piece often compromises the surrounding boards—leading to widespread replacements.
Think of it like pulling a loose thread on a sweater—before you know it, you're unraveling the entire thing. Some contractors may claim they can replace just a few boards, but in reality, they often patch over damage with caulk or filler instead of properly addressing the underlying issue. This temporary fix won't last, and the problem will only resurface later.
Why Choose Nelson Exteriors for Your Siding Needs
At Nelson Exteriors, we believe in long-term solutions, not quick fixes.
