How Long Does a Roof Last?
How long a roof will last depends on the roof, of course. How long a roof lasts depends on how well the roof was installed, the type of roofing material used, the thickness and quality of the roofing materials, maintenance, and the local climate.
An asphalt shingle roof typically lasts around 30 years these days. Copper, clay tile, and slate roofs can last up to 150 years. The latest generation of flat roof membranes last around 30 years.

Factors That Determine Roof Lifespan
There are many factors that go into predicting the length of the useful service life of a roof.
The type of roofing material selected for the roof will set a general limit on the roof’s life expectancy. Some materials simply last longer than others, and all materials have their own design life expectancy. The quality of the materials and the reliability of the manufacturer is also very important when it comes to actually reaching that design life expectancy.
Workmanship, or the quality of the installation, plays a huge part in the life expectancy of a roof system. Roofs that are installed improperly have been known to fail immediately after installation. Seam failure, massive leaking, catastrophic wind blow-off, etc. Even if the workmanship is slightly subpar, the lifespan of the roof will very likely be shorter than it should be as needless problems develop over the life of the roof.
The local environment that the roof will have to endure is also a big piece of it. Roofing materials in coastal regions, with high levels of corrosive environmental salt, tend to deteriorate faster, for instance.
Many types of roof don’t perform well in deserts, with the continual barrage of UV rays. (Asphalt and EPDM rubber should both be expected to last on the low end of the predicted range in a place like El Paso, Texas. Asphalt in general and EPDM flashing material are both highly vulnerable to sunlight.)
The use of proper fasteners and other accessories is crucial to long-term roof performance.
An all-too-common reason for the premature failure of tile roofs, for instance, is the use of low-quality fasteners and battens, which fail long before the tiles themselves would have.
Another significant factor, for flat roofs in particular, is the quality of the roof’s maintenance program. If a commercial flat roof has a rigorous maintenance program that includes full inspections twice a year and addresses maintenance issues as soon as they arise, it can last up to 30% longer than the design life of the system.
All other things being equal, though, it’s the thickness of the material that most affects the expected lifespan of a roof. As a rule of thumb, the thicker the shingle, the panel, the membrane, or the tile, the longer the roof will last.

Length of Roofing Warranties
The warranty periods given in the table are for typical manufacturer’s material warranties. A material warranty only covers the performance of the roofing material itself (basically, it just covers factory defects, which are very rare these days).
The initial workmanship of the roof installation and the performance of other parts of the roof assembly, including the roof deck and any other components not produced by that manufacturer, will not be covered by the manufacturer’s warranty.
Those things will be covered by the roofing contractor’s workmanship guarantee if they are covered at all.
Contractor’s workmanship guarantees last for a much shorter period of time, usually 1 – 5 years.
Many manufacturers have recently changed their warranties to “limited lifetime” warranties, especially for high-end asphalt shingles.
If you read the fine print, however, you’ll see that the coverage becomes “prorated” after 10 – 25 years. This means that the manufacturer starts to guarantee less than the full replacement value of the roofing material at that point, and progressively less and less as time goes by.
About This Roof Lifespan Chart
The following table provides typical expected useful service life durations for various roofing materials and roof systems.
The values for the expected lifespans are based on recent developments in roofing materials technology. The table covers current roofing products, so in some cases the expected service life we give will be significantly longer than what can be expected from older products on existing roofs which were installed years ago.
