The InterNACHI Roof Inspection Checklist

The InterNACHI Roof Inspection Checklist

Owning a home in St. Louis, MO, comes with the responsibility of maintaining its structural integrity, and your roof is one of the most critical components. Regular roof inspections are essential to ensuring your home stays safe, energy-efficient, and free from potential water damage. Leveraging an InterNACHI-approved roof inspection checklist can provide homeowners with a thorough, reliable approach to roof maintenance, ensuring high standards and peace of mind.

What Is InterNACHI?

The International Association of Certified Home Inspectors (InterNACHI) is the world’s leading association for professional home inspectors. InterNACHI certification represents a mark of expertise and adherence to the highest industry standards. When you choose an InterNACHI-certified roof inspection in St. Louis, you’re ensuring that your property is evaluated using the most comprehensive guidelines available.

Why Are Roof Inspections Important for St. Louis Homes?

St. Louis’s climate, with its mix of humid summers, icy winters, and frequent storms, makes roofs particularly vulnerable to wear and tear. Over time, shingles can deteriorate, gutters may clog, and structural damage can occur.

Regular roof inspections not only help identify issues before they escalate into costly repairs but also represent a proactive approach to safeguarding your home against disasters. According to the 2020 report by National Institute of Building Sciences (NIBS), adopting preventive measures like regular inspections can save $11 for every $1 invested when compared to addressing damages after they occur.

This significant return on investment demonstrates the importance of routine maintenance in reducing repair costs, minimizing risks, and ensuring your roof performs optimally through St. Louis’s challenging weather conditions. Additionally, many home insurance providers require certified inspections to validate claims for weather-related damage.

Having a documented inspection history not only protects your financial interests but also strengthens your case in the event of a claim.

The InterNACHI Roof Inspection Checklist

Using the InterNACHI-approved checklist, homeowners can expect a detailed assessment of their roof’s condition. Here’s what a professional inspector typically evaluates:

1. Exterior Roof Structure

  • Shingles and Tiles: Inspectors look for missing, cracked, or curling shingles that can expose the roof deck to moisture. According to data from the National Roofing Contractors Association (NRCA), asphalt shingles, one of the most common roofing materials, typically last 20–30 years but require regular inspections to prevent premature failure.
  • Flashing and Seals: Proper flashing around chimneys, vents, and skylights prevents leaks. Any gaps or signs of deterioration require immediate attention.
  • Gutter System: Gutters and downspouts are checked for blockages, damage, or improper alignment that can lead to water pooling.
  • Soffits and Fascia: These elements protect the roof’s edges and must be free from rot or damage.

2. Interior Roof Inspection

  • Attic Ventilation: Proper airflow prevents moisture buildup, which can lead to mold and wood rot.
  • Insulation Quality: An inspector evaluates the condition and placement of insulation, ensuring it’s adequate to prevent heat loss during St. Louis’s chilly winters.
  • Signs of Water Damage: Inspectors check for stains, mildew, or mold growth on the attic ceiling or insulation that may indicate a roof leak.

3. Structural Integrity

  • Sagging or Uneven Rooflines: These may indicate underlying issues with the roof’s framing or the building’s foundation.
  • Load-Bearing Capacity: Particularly important in areas prone to heavy snowfall, an InterNACHI-certified inspector ensures the roof can handle the weight of extreme weather conditions.

4. Chimney and Skylights

  • Chimney Flashing: Properly sealed flashing around chimneys prevents leaks.
  • Skylight Seals: Inspectors verify the seals around skylights to avoid water intrusion.

To prepare for your roof inspection, consider this checklist:

  1. Follow Up on Findings: After the inspection, review the report carefully. Discuss any recommended repairs or maintenance with your roofing contractor to prioritize actions based on urgency and cost.
  2. Clear Access: Ensure that the inspector has easy access to your roof and attic. Move any obstacles such as ladders or debris.
  3. Document Previous Repairs: Gather any records of past repairs or maintenance work done on your roof. This information can be beneficial during the inspection.
  4. Know Your Roof Type: Familiarize yourself with your roofing system—whether it’s asphalt shingles, metal roofing, or tile—as different materials may require specific attention.
  5. Schedule Preventative Maintenance: Post-inspection, consider preventive measures like applying a roof coating or sealant to extend the lifespan of your roof. NRCA recommends coatings as an affordable way to protect against UV damage and water infiltration.
  6. Monitor After Storms: St. Louis’s unpredictable weather can cause sudden damage. After severe storms, inspect your roof for visible signs of damage, such as missing shingles, dented metal, or fallen debris. Promptly schedule a professional inspection if any issues are detected.
  7. Plan for Seasonal Changes: Before winter, ensure your roof is equipped to handle heavy snow or ice by clearing gutters and reinforcing insulation. In the spring, inspect for any damage caused by freeze-thaw cycles or snow loads.
