Humidity Control: Tips From Raleigh’s Leading Siding Experts

For those living in the Raleigh-Durham Triangle region, we love our beautiful seasons, vibrant communities, and lush landscapes. But here at Robert Gordon Services, we know our humid subtropical climate comes with a hidden threat to your home: moisture damage. The high humidity levels we experience, especially during summer, can wreak havoc on your home’s exterior if not properly managed.

For homeowners in Raleigh, Cary, and Durham, understanding how humidity affects your siding is crucial for protecting your investment. While water intrusion from storms is obvious, the slow, silent creep of humidity can be just as destructive. Let’s explore why this happens and how you can safeguard your home.


The Science of Humidity and Siding

The Triangle area is notorious for its humidity. Moisture damage begins long before homeowners notice. When warm, moisture-laden air meets the cooler surfaces of your home, condensation occurs. If this moisture gets trapped behind your siding without a way to escape, it creates the perfect breeding ground for mold, rot, and structural decay.

Traditional wood siding and poor installation often exacerbate these issues.

High humidity leads to:

  • Significant expansion and contraction, causing wood to crack and warp.
  • Persistent moisture damage once water infiltrates the wall cavity.
  • Rotting sheathing and framing, resulting in expensive structural repairs.

Why a Siding Moisture Barrier is Critical

One of the most effective lines of defense against humidity is a high-quality siding moisture barrier. Also known as a house wrap or weather-resistive barrier, this layer is installed between the sheathing and the siding.

A properly installed siding moisture barrier performs two vital functions:

  1. Water Resistance: It stops liquid water (like rain) from reaching the structural components of your walls.
  2. Vapor Permeability: It allows water vapor from inside the home to escape, preventing condensation buildup within the walls.

If this barrier is missing or poorly installed, your home is at a high risk for serious moisture damage. Many homes in Wake and Durham counties are suffering from improper wrapping techniques that trap moisture rather than managing it. At Robert Gordon Services, we ensure proper moisture barrier protection with every installation.


Common Signs of Moisture Problems

How do you know if your home is suffering?

Keep an eye out for these red flags:

  • Warping or Buckling: Siding boards that look wavy or uneven.
  • Peeling Paint: Interior or exterior paint that bubbles or peels, indicating moisture trying to push through.
  • Mold or Mildew: Dark spots appearing on the siding surface or inside your home on exterior walls.
  • Rotting Wood: Soft spots on wood siding or trim.

You likely already have moisture damage that needs professional attention. Schedule a complimentary moisture inspection with Robert Gordon Services today and protect your Raleigh home before damage worsens.


Avoiding Moisture Problems with Hardie Siding

Many homeowners are turning to fiber cement products to combat our climate. However, simply choosing the right material isn’t enough; installation matters immensely. While fiber cement is incredibly durable, there can still be moisture problems with Hardie siding if it is not installed according to the manufacturer’s strict specifications.

James Hardie siding is engineered for specific climate zones (The HardieZone® System). For the Raleigh area (HZ10), the product is designed to resist cracking, splitting, rotting, and swelling. But even the best product fails if water management isn’t prioritized.

Ensure your Hardie siding prevents moisture damage with:

  •  Proper flashing around windows and doors
  •  Maintaining correct clearances from rooflines and landscaping
  •  Using the appropriate moisture barrier siding system

Schedule A Siding Inspection Today

Preventing moisture damage requires a proactive approach. Regular inspections, keeping gutters clean, and ensuring your landscaping doesn’t touch your siding are good first steps. However, if your siding is aging or was installed incorrectly, replacement with a new moisture barrier siding system might be the most cost-effective solution in the long run.
