How Long Will Your Roof Last? A Complete Guide to Roof Replacement Timelines

With so many roofing companies, types of roofs, and questions surrounding roofs in general, it’s no wonder that people are curious about how often they should replace their roofs.

We are here to answer questions you may have about the roofing industry, its processes, and how often a roof of any type should be replaced. You see, according to the data, the average roof’s lifespan is 25 to 50 years, which in many cases, is generous.

The longevity of your roof comes down to a few factors. We will cover the main factors below.

Typical Roof Replacement Timelines

How Often Does a Shingled Roof Need to be Replaced?

The very first and most common type of roof is the shingled roof. Step outside your door and look around. If you’re in the suburbs, you’re likely surrounded by shingled roofs all the way around. Most shingled roofs are made of asphalt shingles. The asphalt in shingles is mixed with a different binding agent than that of an asphalt road, making it more suitable for its intended purpose.

As we know, asphalt on roads lasts a long time, so that definitely transfers over to shingles. On average, the lifespan of asphalt shingles is 20 to 25 years. 3-tab shingles, however, last 15 to 20 years and architectural shingles, 25 to 30 years.

Asphalt shingles are made by covering a fiberglass sheet with asphalt and then granules are pressed into the hot asphalt. These granules are composed of crushed stone or tiny pebbles. There are different types of granules that can be used in places around the globe, preparing homes for their local climate such as granules that reflect heat for warmer climates or granules that resist algae growth in more humid climates.

The best thing about asphalt shingles is their versatility, affordability, along with ease of installation and repair in comparison with other shingle types.

How Often Does a Wood Roof Need to be Replaced?

A less common type of roof is the wood roof. These types of shingles don’t need to be replaced for an average of 20 to 50 years. Cedar shake is the most common type of shingle for this style of roof and with proper care, a cedar shake roof can last up to 50 years. In most cases, however, this type of shingle will last in the 30 year range. This is because of the maintenance and the quality of the shingle you’ll be receiving.

Wood shingles are cut from several types of wood besides western red cedar; cyprus, pine, and redwood are also very common. To create a shingle, these types of wood are cut into thin and measured pieces.

How Often Does a Metal Roof Need to be Replaced?

What do you know about metal roofs? As of late, they’re becoming more popular by the year. The issue with metal roofs is the expensive cost homeowners incur when purchasing, along with some inflexibility in color and design. On average, a metal roof lasts 40 to 70 years, this depends on the type of metal that is used. The two longest lasting metals for these roofs are copper and zinc. If zinc is used, the roof can last over 100 years with proper maintenance. The problem with metal roofs is not only what was mentioned before, but also that they can be incredibly noisy and easily damaged. In most cases, a metal roof just isn’t practical.

How Often Does a Flat Roof Need to be Replaced?

Flat roofs typically have a lifespan of 15 to 30 years. As mentioned for the other types of roofs, this depends on the quality of workmanship, materials used, and maintenance that the homeowner is doing for the home.

Flat roofs are often one of the easiest types of roof to determine that it needs to be replaced. There will be visible signs of damage, such as pooling water, roof leaks, rusted fasteners, clogged gutters and drains, mold growth, or even structural damage. 

This is why many homeowners opt to install a pitched roof over their flat roof. Pitched roofs withstand the elements better, improving the roofs ability to shed water and snow from its grasp. A pitched roof can also provide additional structural support!

How Often Does a Composition Roof Need to be Replaced?

A composition roof can last up to 50 years. These types of roofs are made using composite shingles which are made from a variety of materials including asphalt, glass fiber, ceramic, wood fiber, slate, and paper. With proper maintenance, a composite roof can be a great choice for a home. Another added benefit to this type of roof is its fire resistance. The only real downside is the cost in comparison to other common roofing types.

When a composite roof is properly maintained, it can bring big savings to your energy bills. A composite roof can also bring the desired curb appeal you may be looking for, as these roofs can be made to look like other types of roofs such as cedar shake or slate roofs with proper molding.

How Often Does a Tile Roof Need to be Replaced?

Tile roofs can last for a long time, 50 to 100 years in fact. However, it’s important to note that like all other roofs in this article, there are factors that swing the lifespan heavily in one direction over the other.

With tile roofs, maintenance is key. If there is not proper maintenance for this type of roof, weather will surely be its biggest concern. With proper maintenance, you will be able to diagnose any issues that may arise from this roof type such as signs of water damage on exposed eaves, or slipped tiles, which may expose underlayment to the sun causing it to burn.

Tile roofs are often made of slate or clay. However, composite, porcelain, or copper are also great options for getting a tile roof that meets your aesthetic and functional needs.
