All roofing systems have average lifespans, and regular maintenance extends your roof’s life expectancy to the maximum length. But what are the different lifespans and how do they vary between roof types? Let’s look at the different types of commercial and residential roofs and their lifespans. Then you can determine what your roof’s lifespan is and where it currently is in that lifespan.
Commercial membranes’ roof lifespans vary depending on the materials used in the membranes. These materials include:
- Thermoplastic Polyolefin (TPO): TPO membranes are roof membranes that last for 10 years at the bare minimum. With proper maintenance, they last for 22 to 30 years. They often deteriorate at their seams, but your roofing contractor can repair any unsecured seams to extend the roof’s lifespan.
- Ethylene Propylene Diene Monomer (EPDM): An EPDM roof membrane is another type of rubber roof membrane. These membranes usually last 22 to 35 years.
- Polyvinyl Chloride (PVC): PVC roof membranes are flat or low-slope membranes that last for about 25 to 30 years. They have a reputation for being extremely durable because they contain materials such as UV stabilizers and cool roof pigments that reduce damage on these membranes.
- Fiberglass and Emulsion Roofing: A fiberglass and emulsion coating goes on top of a flat or low-slope roof membrane. It consists of an asphalt emulsion, fiberglass gun roving, polyester sheeting, and solar reflective shield coating. It adds 10 to 20 years to your existing membrane’s lifespan.
- Metal Roofing: Metal roofs’ lifespans vary widely, often ranging from 20 to 70 years. The roofs’ lifespans vary due to the different thicknesses of metal used in each one. Unlike the flat membranes listed above, metal roof systems are usually steep-slope roofs.
Roof lifespans matter for residential roofs as well as commercial ones. After all, you want your home to keep you safe and comfortable throughout the year. Let’s look at some common residential roof lifespans:
- Asphalt Shingles: Are you wondering, “How long do shingles last on a house?” Asphalt shingle roofs usually last for about 20 to 40 years. There are two main types of asphalt shingles: three-tab and architectural shingles. Three-tab shingles are a lower-priced option, but they don’t often last for a full 40 years. Architectural shingles are often three times thicker than their three-tab counterparts, so they create stronger, denser roof systems. They usually last for up to 40 years.
- Wood Shakes: Wood shake roofs are steep-sloped roof systems that consist of cedar shakes. These shakes are natural roofing materials that come from split cedar logs. These roofs last for about 30 years, though they can last up to 50 years in certain weather conditions. They resist heavy rains, strong winds, thick snowfall, and powerful hailstorms.
- Slate Tiles: Slate tiles last over 100 years when maintained properly. However, they require specialized roofing skills to install and maintain them properly. Roofers often check these systems for cracked or broken tiles that could shorten their lifespans if left unattended.
- Clay Tiles: Clay tile roofs often last upwards of 50 years. Like their slate counterparts, they could have shortened lifespans if they aren’t checked for broken or cracked tiles. They also require specialized roofing knowledge to ensure they receive proper maintenance.
Not sure which roof type fits your building or home? Reach out to us today to find out.
When you choose a new roof, consider what type of roof slope your building or home has, how long each roof type’s lifespan is, and how much you want to invest in roof materials and maintenance. You’ll have to make tradeoffs between these different factors when you select a roof type.
For example, slate and clay tile roofs last for a long time, but they require expensive materials and specialized maintenance techniques. On the other hand, asphalt shingles are much cheaper and require less specialized maintenance, but they don’t last as long as clay and slate roofs do. Reach out to your roofing contractor for advice on choosing the best roofing system for your needs.
