Different roof materials can make a huge impact on the lifespan of your roof. So asking how long does a metal roof last and how long does a shingle roof last can result in very different estimates.

What Factors Influence My Roof’s Performance?

When we tackle “How long does a roof last?”, we break down the question into several factors. What type of roof do you have? How is your ventilation? Here are the four biggest factors that influence your roof’s performance over the years.

  • Materials: Not only do different roof materials affect your roof’s performance, but the quality of these materials is also important.
  • Underlayment: Underneath your roof materials is a waterproof layer known as “underlayment”. This can greatly prolong your roof’s lifespan, especially in areas like Illinois with harsh winters.
  • Ventilation: Ventilation is unique to each home, so it’s worth an inspection to find out how to improve your home’s setup. Adding options like power vents, ridge vents, eave vents, and other ventilation systems can help your roof avoid rot.
  • Installation: Choosing the right roofer can make a huge difference in your roof’s performance as well. The right roofer will know the best practices for your region, your roof materials, and your house design.

Longevity of Different Roof Materials

Everything from installation technique to local weather can affect your roof. While some roofs can last 70 years, others may need serious work in 20 years. And while you can’t control the weather, you can choose between a wide variety of roofing materials to suit your local climate. Take a look at some of the different roof materials commonly used in the Chicagoland area:

  • Asphalt shingles: One of the most common and affordable roofing types available, asphalt shingles can last between 15 and 30 years with proper installation.
  • Wood shingles: Though wood shingles need more maintenance than other types of roofing, a properly-maintained wood roof can last up to 30 years.
  • Clay tiles: Clay tiles are an investment, but this material is both durable and low-maintenance. Many options come with warranties lasting well over 30 years!
  • Metal roof: The most durable of all, metal roofs can last over 70 years – but installation can be pricey.
