One thing that not a lot of people consider is their roof and how long it should last before it needs replacing. It applies to both residential and commercial properties. Indeed, many only ever think about the roof when something goes wrong. Does this sound familiar to you? In light of this, we thought we’d discuss how long a roof should actually last.

Texas-based company 1st Choice Commercial Roofs tell us that the life of any roof will depend on a number of factors. These experts in commercial roof repair say that maintenance is a key element in how long a roof lasts. The type of material it is constructed from is also important.

Roofing Materials

In general, a roof should be guaranteed to last for between 15 and 25 years. That seems quite broad doesn’t it, but it is all dependent on the above-mentioned construction material. It also depends on the climate where the building is situated. For example, if you had an asphalt 3-tab shingle roof, it might last around 25 years in a temperate climate. However, the lifetime of a similar roof could be cut to just 15 years in a state that is prone to storms or one like Texas where roofs are exposed to very strong, direct sunlight.

You can expect a roof to withstand more extreme weather if the material used is stronger; think along the lines of architectural shingles or premium shingles here.

Metal roofing is harder wearing than shingles and is often used in commercial builds. In the right environment and with careful maintenance, metal roofing can last for anywhere up to 50 years. Metal shingles and standing seam are two popular roofing choices, with shingles being the less expensive option.

How to Tell that Your Roof Needs to be Repaired or Replaced

It doesn’t matter if your roof is commercial or residential, if it is damaged it will either need to be repaired or replaced (hopefully the former as a new roof can be very expensive). There are certain signs to look out for that could indicate you have a problem with the roof that needs to be addressed.

Cracked Shingles

Shingles on a roof can crack over time in certain conditions. Southern states like Nevada and Texas have predominantly desert-type climates, which means roofs have to be able withstand strong sunlight. When shingles begin to crack, they do need to be repaired or replaced as soon as possible.


Direct sunlight not only contributes to cracked shingles, it can also cause buckling or curling. If this happens, it is worth calling in roofing experts to check it out. If you are lucky, it may be just a few shingles that need to be replaced.

Missing Tiles

It sounds obvious but if you notice that some of your roof tiles or shingles are missing, it is time to call in the experts to have a look. Leaving the roof with missing tiles/shingles could exacerbate the problem, possibly ending up with a leaking roof.

The Importance of Regular Maintenance

If you are like most, you have never given a second’s thought to the roof on your home or commercial property. Nevertheless, it pays to keep this essential part of your building in good order. Check under the roof regularly to see if you can see daylight coming through. Even if you do not see light, check the insulation to ensure it is not damp. Moisture in the insulation could mean holes in the roof.

A well-maintained roof can last between 15 and 50 years depending on materials used. To get the most out of your roof, get into the habit of having it checked annually.
