How Often Should You Replace A Roof

Replacing a roof is a big project. Most homeowners do not even think about saving money for a project like a new roof. In most cases, homeowners only expect to replace their roof if there is significant damage to it. No matter where you live, a storm can always cause some form of damage. However, you might get lucky and never have damage from a storm. So, does that mean your roof last forever? Probably not. How often should you replace your roof? Depending on the type of roof or the need for a new style, it should last between 15-30 years.

Let’s take a look below at what this means.

How Would I Know

Determining if your roof needs to be replaced should be evident by various signs. Keep in mind that the condition of your roof should be easily determined by a quick inspection. Let’s take a look at the obvious signs you need to replace your roof.

  • Greenhouse – if there is mold, moss growth, or mildew growing on your roof and making it look like a planter bed, this might be a good time to clean your roof. After cleaning the roof you can determine what the damage is to the roof and work towards a solution.
  • Light exposure – if there is suddenly sunlight in your home that is not a result of a window, this might be damage to your roof. Holes in the roof absolutely mean it is time for a replacement.
  • Chimney damage – if the flashing or other chimney parts are damaged, this could mean a roof replacement is not far behind.
  • Drooping or sagging spots – if you notice that your roof decking is buckling in or the shingles are breaking apart, it is time for a roof replacement. Get an inspection to be certain what repairs are needed.
  • Outer damage – damage to the roof can reduce its lifespan. Also, letting the damage go without repair will only increase the likelihood of more damage occurring.
Homeowners might want to try a new roof type. This might be a good time to replace your roof.

What Are The Lifespans For Each Type

Depending on the type of roof you have chosen to install determines the lifespan of your roof. Let’s take a look at which materials last the longest.

  • Wood Shakes – this material is thicker than a shingle and resilient to weather or UV rays. Typically, they last between 35 and 40 years.
  • Wood – your wood shingles will typically last between 25 and 30 years. They require maintenance in order to sustain longevity and they are different from asphalt shingles.
  • Asphalt – when it comes to architectural asphalt shingles you can typically see a lifespan of between 15-20 years. They are more resilient to the elements outdoors because of their design.
  • Slate – a highly durable material that requires quality maintenance for longevity. If you properly maintain your slate roof the lifespan will be at least 100 years.
  • Clay or cement tile – a clay or cement tile roof will usually last between 50 and 100 years. These roofs are very heavy, however, very resilient to the elements.
  • Metal – installing a metal roof is a great idea. Metal roofs allow you to keep UV rays off the home as well as stand up to severe weather conditions. Typically, a metal roof will last you 50 years or more. It all depends on how well you maintain the roof materials.

How Much Do They Cost

Replacing your roof can be a very expensive project. Due to the size and the type of material that you have chosen to use on the roof, the project can be in the high thousands. Most shingled roof replacements are going to cost between $8,000 and $15,000. However, if you have a composition roof, those likely will cost between $20,000 and $30, 000 to replace. Keep in mind that the cost per square foot is typically between $5 and $15.

Other Recommended Maintenance

Now that you are up to speed on when to replace your roof, you can consider getting a roofing inspection checklist put together. Having a roofing inspection checklist saves you from wondering how much the project might cost and what it involves.

Next, it is a good idea to read up on getting your chimney inspected. If you have a fireplace with a chimney, you will want to ensure that it is in good working order. Damage to your chimney can cause damage to your roof. This will reduce the longevity of your roof.

Lastly, while you are getting your roof replaced, you might end up discovering mold in your home. If the mold is substantial you will need to hire a mold remediation company. Now would be a good time to read up on how long mold remediation takes. You might be able to have mold remediation done at the same time as your new roof. This will save time and money.

Always hire a professional when it is time to replace your roof.

When Do I Call A Professional

When it comes to getting a new roof, you will need to hire a professionally licensed roofer. Roofing contractors are available, however, you will want to hire a reputable one. Don’t make the mistake of hiring just any roofing contractor. Call on your local home inspection team so that they can inspect your roof and determine what repairs are needed. Also, they can recommend a reputable roofing contractor.


If your roof is old or you are just looking to change the curb appeal, consider replacing your roof. Keep in mind that your roofing project could take a couple of days to complete. Your roofing contractor must remove the old roof and discard it into a dumpster and then install your new roof. Be sure to save your money so that you can purchase the style of roof that makes your home outshine the rest.
