How Often Should You Replace Your Roof?

Your roof’s lifespan depends largely on the material it is made of. Different materials have different lifespans and are susceptible to different types of damage. Below are some of the most common roofing materials and their average functional lifespans. 

Asphalt Shingles

Asphalt shingles are probably the most common type of roofing material and have the lowest lifespan. Asphalt shingles last about 20 years, though climate conditions can affect their longevity. In particular, asphalt shingles are susceptible to impacts and can fade and crack from excessive sunlight and heat. 

Ceramic Tiles

With appropriate care and maintenance, a ceramic tile roof can last about 50 years on average. Ceramic is highly resistant to water and environmental weathering, although the tiles can crack and shatter from physical impacts and can be ripped from your roof due to high winds. Ceramic tiles are also heavy, so your roof might need additional supports installed to bear the additional weight. 


Slate roofs are made from natural stone and boast incredible longevity. A slate roof can last up to 100 years, making it a good option for homeowners who won’t want to have to reroof in their lifetimes. Slate is also recyclable, making it an eco-friendly option. 


Metal is another durable material that can last around 70 years with proper care and maintenance. Treated roof metals are resistant to chemical and environmental weathering, but they can be tricky to install due to their increased weight.

Membrane Roofing

Flat membrane roofing is made from synthetic materials and can last about 30 years on average. Between TCO, PVC, and EPDM membranes, EPDM is the most durable and has the longest lifespan. Like shingles, membrane roofing lifespan can depend heavily on local environmental conditions. 

Signs You Need to Replace Your Roof

If you notice any of the following signs with your roof, contact an expert roof construction company to discuss replacement options. 


Age is the most obvious indicator of how often you should replace your roof. Even if your old roof is still in decent condition, replacing it can be a benefit as new materials are longer-lasting and more energy-efficient, which can save you money in the long run. 

Curled Shingles

Crackled and curled shingles are a common sign your roof has outlived its usefulness. Curled shingles can expose the roof decking below, creating drafts and points for potential water infiltration. Deformed shingles also create gaps in your roof coverage, which causes more heat to leak out of your home. 


Roofs can also sustain structural damage from wear and tear and storms. If your roof is sagging near the midline, it most likely has structural damage and will require either a partial or full replacement. Roofs with structural damage pose a major safety hazard so contact an expert as soon as possible to address the issue. 

Dark Streaks or Rust

Black streaks on roofs are a sign of algae and mold, and they contribute to the degradation of your roofing materials. Black streaks are most common on asphalt, but they can also occur on stone, ceramic, and membrane roofs. Metal roofs can also develop reddish-brown streaks from rusting. 

High Energy Bills

As roofing materials age, they are less efficient and create more heat leakage. A common sign that your roof is getting old is if your energy bills start to spike more than normal during the summers and winters. 

Benefits of Roof Replacement

Roof replacement is a worthwhile project that carries several benefits. 

Fewer Repairs

After a certain age, roof repairs start providing diminishing returns. New roofs use advanced and tougher materials, so you will spend less on repairs and maintenance over their lifespans. You can use that saved money to invest in further projects to increase your home’s resale value. 

Better Performance

New roofing materials will also perform better. They will do a better job protecting your home and will produce less noise than an old roof with problems. You can rest easy knowing your home will be safe from the environment and comfortable for you and your family. 

Lower Energy Bills

Experts estimate that the average roof is responsible for about 25% of a home's energy leakage, so replacing an ailing roof can greatly reduce annual heating and cooling bills. Advances in roofing material manufacturing make newer materials more energy-efficient. 

Should I Repair or Replace My Roof?

If your roof has sustained damage, you might be wondering whether you should repair the damage or replace the entire roof. It can be tricky to know when your roof just needs some extra care and when it’s time to get a new one. Whether or not you should get roof repair or roof replacement will depend on the total cost of the project. 

As a general rule of thumb, you should replace your roof if the cost of repair is at least 50% of the cost of replacement. In that case, getting a new roof can be the smarter financial decision because you will spend less on repair and maintenance than you would on the older roof.
