Costly or cheap, of course, all roofs deteriorate over time, and while the lifespan of each roof is different, it still comes down to how often one should replace a roof.

An average roof can typically last 25-50 years, and that’s how often you should replace it. Depending on the durability and longevity, some roofs, like copper and tile roofs, can extend this time range.

Other factors like the condition of your roof can also determine when you need to change it; we will come to that soon.

In this article, we will look into the average lifespan of different roofing materials, when to replace your roof, and how you can extend the life of your roof for the better.

How Long Does A Roof Last?

The average lifespan of a roof ranges from 25-50 years, but to be more specific, the most common roof in the US is Asphalt shingles, so we are talking about 20-30 years on average here. Considering factors like rain on roof before shingles can also affect longevity.

The lifespan of a roof primarily depends on the roofing material type. You cannot just expect an Asphalt shingle roof to last as much as a slate one does. 

The exact answer to how often your roof should be replaced lies in that.

Average Lifespans Of Different Roofs

The wide range in the lifespans of roofing systems is attributed to the diverse spectrum of available roofing materials. 

Go through the table below:

Roof TypeTime Span
Metal Roof40-70 years
Tin Roof50 years
Shingle Roof15-30 years
Thatched Roof15-30 years

How Long Does A Metal Roof Last?

A typical metal roof can last between 40-70 years. Metal roofs are about twice as expensive as asphalt shingles, but that is understandable considering their energy efficiency and durability.

You can choose anything with different characteristics: aluminum, copper, zinc, or tin roofing. Steel roofs are the most commonly and widely used among the metal roofs family. 

How Long Does A Tin Roof Last?

Tin roofs, originally known as “Tin-plates,” consisted of iron coated with tin and lasted 50-100 years.

Tin roofs have excellent fire-resisting properties and are long-lasting, so it’s worth it if you have your eyes on it.

How Do I Know When To Replace My Roof?

Let me take you through the obvious signs you might need to consider replacing your roof for. 

1. Age Of The Roof

It might deteriorate if you notice your roof requiring frequent repairs for no obvious reasons, like heavy rains or storms. 

And if that’s the case, no amount of repairs will fix that bad boy.The only thing you can do is replace your roof, considering the average time for roof replacement, and that’s for the good, right?

If your roof is still pretty new, you don’t necessarily need a replacement, but there might be some technical problems, like installation issues, that need to be addressed.

2. Sagging Roof

I want you to go out and look at your roof. Does it have that curvy appearance? Like not flat but curved, kind of?

That is probably a sagging roof, the major sign of an aging roof that screams “replacement.”

3. Water leaks

A few leaks in roofs are common over time, but if you have got multiple in yours, you need to replace it before the damage grows and reaches other parts of the house. 

Water leaks can develop if any part of the roof is left exposed to weather elements like the rain or hail, it can soften the decking and cause a financial wreck. 

4. Missing Or Cracked Shingles

If your roof has received massive damage from a falling tree and is now missing shingles up to at least 30%, you don’t have any other option to reflect on but replacement. 

Cracked Shingles

The same goes for cracks, too. Minor cracks in shingles are fine, but if they are large and many, potential leaks can develop, which is why replacement is important.

5. Rust Or Corrosion On Metal Roofing

Rust and corrosion can commonly indicate standing or slow-leaving water. In that case, the shingles can corrode, and you can notice rust on your roof.

Replacement is a good option to avoid further damage to the roof. Other options, like rust-free paints, can only provide a timely solution.

6. Pest Infestation

Pest infestations are common in shaded areas and can decrease a roof’s lifespan by up to 10 years. Years and increased chances of collapse.

What causes pest infestation in roofs? The moisture from elements can cause mildew overgrowth that is an invitation link to wood-destroying insects like termites.

These grow into colonies; the only way to stop them is to replace the roof before they invade your attic space!

  • Cut any long trees in the surroundings that might be blocking the sun from reaching your roof.
  • Make sure that the gutters are not blocked, and maintain routine cleaning.
  • Make sure the attic insulation is fine enough to prevent the damage.
