How often does a roof need to be reshingled

As a homeowner, maintaining the integrity of your roof is crucial to protecting your home from the elements and ensuring it remains a safe and comfortable living space. One common question that arises is: how often does a roof need to be reshingled? The answer to this depends on various factors, including the type of shingles, the climate, and the quality of the initial installation. In this comprehensive guide, we will explore these factors in detail and provide insights to help you determine the optimal schedule for reshingling your roof.

Types of Roofing Shingles and Their Lifespans

Different types of roofing shingles have varying lifespans, and understanding these can help you estimate when your roof might need to be reshingled.

  1. Asphalt Shingles: The most common roofing material in North America, asphalt shingles typically last between 20 to 30 years. However, high-quality architectural shingles can last up to 50 years.
  2. Wood Shingles and Shakes: These offer a natural aesthetic and generally have a lifespan of 20 to 40 years, depending on the wood type and maintenance.
  3. Metal Shingles: Known for their durability, metal shingles can last 40 to 70 years with proper maintenance.
  4. Slate Shingles: Among the most durable roofing materials, slate shingles can last over 100 years but require specialized installation and maintenance.
  5. Clay and Concrete Tiles: These tiles can also last up to 100 years, but their heavy weight requires a strong roof structure.

Factors Affecting the Frequency of Reshingling

Several factors can influence how often you need to reshingled your roof:

  1. Climate and Weather Conditions: Extreme weather conditions such as heavy rainfall, snow, hail, and high winds can accelerate the wear and tear on shingles, shortening their lifespan.
  2. Quality of Installation: A properly installed roof will generally last longer and perform better under stress than one that was poorly installed.
  3. Roof Ventilation: Proper ventilation helps regulate temperature and moisture levels in the attic, which can extend the lifespan of shingles.
  4. Maintenance: Regular inspections and maintenance, such as cleaning gutters and removing debris, can prevent damage and extend the life of your roof.
  5. Roof Slope and Orientation: Roofs with steeper slopes and those facing south tend to last longer because they shed water more effectively and dry faster after rain.

Signs That Your Roof Needs Reshingling

Knowing when your roof needs to be reshingled is essential to prevent extensive damage. Here are some signs to look out for:

  1. Curling or Buckling Shingles: Shingles that are curling or buckling are a clear indication that they need to be replaced.
  2. Missing Shingles: If you notice any missing shingles, it’s crucial to replace them promptly to avoid water damage.
  3. Granule Loss: Check your gutters for shingle granules. A significant amount of granules means your shingles are wearing out.
  4. Leaks or Water Damage: Water stains on your ceiling or walls indicate that your roof is no longer providing adequate protection.
  5. Age of the Roof: If your roof is approaching the end of its expected lifespan, it’s time to start planning for reshingling.

The Reshingling Process

When it’s time to reshingled your roof, understanding the process can help you prepare:

  1. Inspection and Assessment: A professional roofer will inspect your roof to determine the extent of the damage and the best approach for reshingling.
  2. Removing Old Shingles: The existing shingles are removed to check the underlying structure for any damage.
  3. Repairing the Roof Deck: Any damaged sections of the roof deck are repaired or replaced.
  4. Installing Underlayment: A waterproof underlayment is installed to provide an additional layer of protection.
  5. Laying New Shingles: New shingles are laid starting from the bottom edge of the roof, ensuring they are properly aligned and secured.
  6. Final Inspection: The completed roof is inspected to ensure all shingles are properly installed and the roof is watertight.

Professional vs. DIY Reshingling

While some homeowners may consider reshingling their roof as a DIY project, it’s often best to hire a professional. Professional roofers have the experience, tools, and safety equipment needed to perform the job correctly and efficiently. They can also identify underlying issues that may not be apparent to an untrained eye.


Determining how often a roof needs to be reshingled depends on various factors, including the type of shingles, climate, and overall maintenance. Regular inspections and maintenance can help extend the life of your roof, but being aware of the signs of wear and tear is crucial to prevent significant damage. By understanding these factors and the reshingling process, you can make informed decisions to protect your home and ensure its longevity.
