What is the Average Life of a Roof?

There is no hard and fast rule to determine the life of a roof. There are several factors at play here. Things like weather conditions, roofing material, and periodic maintenance all play a very important role in determining how long your roof will last. Asphalt shingle roofs on average last for around 15 to 18 years given the proper maintenance is done. Not every roof or roofing material will last as long and could run into some serious issues much earlier.

Factor That Determines the Lifespan of Your Roof

Like mentioned before, each roof’s lifespan will depend on various factors. Here we will take a look at some of the important factors that affect the lifespan of your roof.


Roofs made from darker materials will generally absorb more heat and consequently heat up more. This reduces the lifespan to a greater degree. Lighter-colored roofs outlive the darker ones.


While it is a hassle to install high-pitched roofs due to the technicalities involved, they are almost always better than flatter roofs because they brush off excessive moisture very easily and quickly.

Roof Service Orientation

A roof that faces the south will absorb more sunlight especially if there is no tree to cover the sunlight. This means that one side of the roof will become much hotter than the other and in turn affect the overall life of your roof.

Multi-Layer Roof

If a roof is installed on an existing roof, this will definitely affect the lifespan of the roof.

Quality of roof material

This doesn’t need to be said but roofs that are made of quality material will obviously last longer than the roofs that are made from cheaper material


Improper or sloppy installation work will definitely affect the roof in a bad way.

Attic ventilation

A poorly ventilated attic will reduce the roof’s lifespan due to the fact that the moisture is vented properly.

Trees near roof

If there are trees near your roof that come in contact with it, they can brush off the outermost layer of your roof and can make it susceptible to moisture damage.

Harsh climate

If you live in an extreme weather area whether it’s too much heat or cold, it will have a negative effect on the lifespan of your roof. Roofs installed in the moderate climate area last much longer than roofs in the colder or hotter regions.
