How Often to Replace a Roof
If you asked most car owners if they would ever let their vehicle go without maintenance work and oil changes, the answer would almost inevitably be no. But if you asked most homeowners how often they performed routine maintenance checks on their roof, you might get quite a different answer. The truth is, most people don’t pay attention to their roof until it springs a leak, or until they start to notice the shingle falling off. Why this is, we’re not really sure, but the truth is, you should be inspecting your roof on a regular basis to identify problems before they occur. So today, we will teach you how to look for “when to replace a roof” signs so that you can prevent small problems before they become big ones.
How often do you need to replace a roof?
The answer to this question really depends on numerous factors including:
- Where you live and the climate around you can play a drastic role in the lifespan of your roof. Let us just say that humidity is your roofs worst enemy. Beyond that, high precipitation levels, including snow, sleet, rain, and hail, can also all decrease the expected lifespan of your roof. During winter when weather is fluctuating in temperatures, freeze thaw cycles can lead to a host of roof concerns.
- Proper ventilation
- In order to protect your roof from the cold of the winter and the heat of the summer, proper ventilation is required. Good ventilation can help to keep air circulating, preventing your roof from getting too hot or too cold, and can thereby extend the lifespan of your roof.
- Routine maintenance
- Just like anything else that you own, the better you upkeep it, the longer it will last. If you are willing to put in regular maintenance work and keep up with small repairs, your roof will last longer. If you aren’t, lifespan can be shortened.
- Dirt, debris, and rodents
- Over time, your roof can attract a lot of dirt and debris. It’s important that you regularly clean your roof to prevent buildup, which can impact your roof’s lifespan. Rodents can also cause a lot of damage to roofs, so it’s in your best interest to keep them away.
Having said all of that, most roofs last an average of between 25-30 years. Depending on the type of materials used to build your roof, this statistic may be higher or lower. So let’s talk a little about roof shingles to give you a better estimate:
When to replace roof shingles:
The type of shingle material you use can drastically impact the lifeline of your roof. As we just mentioned, the average lifespan of a roof is between 25-30 years, but if you go with a less robust shingle like composition shingles, this statistic can decrease to an average of 12-20 years.
On the opposite end of the spectrum, choosing a strong and sturdy material like metal roofing can drastically increase the lifespan of your roof between 50-75 years.
Other roofing materials that fall somewhere in the middle include Asphalt shingles (with an average lifespan of between 15-30 years), and wood shingles (expected to last between 20-25 years).
Signs that it’s time to replace your roof:
So we now know what can impact the lifespan of our roofs, and we have a good estimate of when to replace a shingle roof, but how do you know it’s really time? Here are some key signs that will tell you it’s time for a new roof:
1) Your roof is over the age of its estimated lifespan
2) Your shingles are starting to curl or buckle

Added bonus: When to replace roof decking
Roof decking is the section of your roof by which everything else is placed. It includes things like the trusses and joints, the insulation and coating, the layers, the wood, steel, or concrete, and so on and so forth. Decking materials hold several different purposes including supporting the shingles, preventing fires, providing protection from the elements, and preventing leaks..
Like the shingles themselves, roof decking is subject to damage and will eventually need to be replaced. Signs of decking damage can be very similar to signs that tell you it’s time to replace your shingles. They include:
- The curling or buckling of shingles/missing shingles
- Granular wear of shingles
- Mold or mildew buildup in the attic
- A bouncy feeling when walking on the roof
- Holes in the roof
- Damage found around pipes, chimneys, or other areas
So if you have a roof that is past its due date, or that is showing signs of wear, it may be time for a replacement. But before you replace, call the professionals to take a look – they can tell you whether you need a full roof replacement, or simply just need some maintenance work.
