Are you wondering, how often does a roof need to be replaced? Determining when exactly you need a replacement depends on a lot of factors.
Are you wondering how often does a roof need to be replaced? The lifespan of your roof is dependent on many of factors, including:
Regardless, we have all the answers you’re looking for.
We’ll start by explaining how long your roof should last on average, depending on the materials used. Then we’ll go over the various factors that can affect your roof’s lifespan and what they mean for you.

AVERAGE LIFESPAN OF A ROOF
The different types of roofs have different lifespans. So, we’ll start by listing our estimates of average roof lifespans based on the roofing material used.
Under normal circumstances, 3-tab asphalt shingle roofs should last 15-20 years before needing replacement. However, architectural asphalt shingle roofs are a bit more resilient to the elements due to their design. These may last up to 10 years longer than 3-tab asphalt shingle roofs.
How often does a roof need to be replaced?
Clay/concrete tile roofing is one of the hardiest roofing options there is. Not only are the tiles very resilient, but they’re also heavy. These tiles are installed on top of extra-sturdy roofing reinforcement, which means even more protection for your home.
For these reasons, tile roofing is highly durable and will last from 50 to even 100 years.
Slate is by far the most durable roof you can buy. In most cases, it will last 100 years or longer.
Wood shingles usually last 25-30 years. But they require maintenance, which affects their lifespan.
For example, if you don’t keep the roof clear of leaves and moss growth, they trap moisture against the roofing, encouraging decay. But, if you keep up on the necessary maintenance, you might get 50 or so years out of your wood shingle roof.
Wood roofing is also particularly susceptible to damage by fire. Thus, it is hazardous and illegal to install in specific locations as it can quickly go up in flames.
Since wood shakes are thicker than shingles, they’re more resistant to factors like UV rays and harsh weather. These roofs should last for 35-40 years.
But, again, maintenance is a factor. How well you maintain a wood-shake roof determines how long it lasts.
Metal roofing is another very resilient roofing choice. Standard metal roofing materials, like steel and aluminum, should last 50 years before needing replacement. Other metal roofing, like zinc and copper, can last 100 years or more.
Here are some of the tell-tale signs that it is time to call Grennan Construction to talk about a new roof:
Possible causes: Leaky or inadequate shingle underlayment or deteriorated flashing
Possible causes: Inadequate shingle underlayment or inadequate attic ventilation
Possible causes: Excessive temperature or high humidity due to inadequate attic ventilation
Possible reasons: Inadequate or faulty shingle underlayment allowing leakage or inadequate attic ventilation
Likely cause: Inadequate attic ventilation
Possible cause: Shingles have reached the end of their useful life
Possible causes: Environmental pollutants; vegetation, fungus, or algae; loss of granules due to age of shingles
Possible cause: Insufficient attic ventilation
In warm weather, inadequate ventilation will trap hot air in the attic, causing air conditioning systems to work harder, or leaving your home’s interior hotter and less comfortable. In both hot and cold weather, insufficient attic ventilation may cause moisture in the attic to become trapped and condense on the rafters. This condensed moisture can drip down onto the insulation and reduce its effectiveness. High energy costs can result.
Based on the information in this guide, you should now know approximately how often to replace your roof. Just look up the average lifespan based on the roofing material in the list above. Then, look for the listed signs of damage on your roof.
Of course, you’ll still need to know the age of your roof for this information to be relevant. Thus, you may yet have more questions.
