The useful life of an asphalt roof is expected to be very durable over time, however, this useful life will depend on the materials used, the quality of the installation, preventive maintenance and the climatic conditions of the location area. An asphalt roof with the aforementioned factors properly applied can last between 25 to 40 years.
One of the most typical roofs are asphalt shingles, which have been around since the 1920’s, are composed of a layer of asphalt over a glass or organic cellulose base which, because of their long durability, are affordable and generate confidence in the choice of roofing material. In the U.S., this type of shingle lasts longer in cold climates than in warm climates.
Factors that affect the life span of an asphalt roof
Is the quality of the material used the best?
The quality of the material offered by the contractor should have the best possible guarantee, the choice of asphalt shingles whether fiberglass or organic cellulose shingles, are different in terms of benefits, cellulose shingles are thicker, heavier because they have more asphalt, more durable, but more expensive, while fiberglass shingles are lighter and are better fire rated.
Is the roofing contractor who performed the work reputable?
A contractor’s reputation is of great value when it comes to installing a roof, based on their work history. This depends on the choice of the best quality materials, warranty, good installation technique, legal knowledge, good work team, among others, which will help to extend the life of the roof.
How are the climatic conditions of the area where you live?
The climatic conditions have a direct influence on the useful life of the roof, depending on the amount of extreme weather it will affect the asphalt of the roof due to the wear and tear to which it is exposed. Shingles are affected by granular loss when they receive small hail in winter, the accumulation of water due to constant rainfall increases the wear of the shingles. In summer with high temperature levels, they limit the useful life of the shingles and other roofing materials.
Is the attic well ventilated?
One factor that affects the life of a roof is proper ventilation. A good attic that allows ventilation of trapped hot and cold air is very important, as this can deteriorate the roof and the solution is to replace it.
Is the roof maintained every year?
The recommended maintenance for asphalt roofs is done continuously and properly once a year, since shingles of any kind are affected by the impact of weather, accumulated debris either from trees or any other sediment such as algae, fungi, poor ventilation or poor installation, this translates into a drastic reduction in the life of the roof.
What color and slope does your roof have?
Light colors are more recommended because they keep heat away, while dark colors reduce the life span because they absorb more heat. If a roof is not sloped, debris buildup is easily retained which causes long-term damage to roofs, so it is recommended that the roof have a steeper slope for longer roof life.
When to replace an asphalt roof?
We’ve already outlined the factors that impact the lifespan of an asphalt roof, but if your roof is beyond repair and you need to replace it, this job can take anywhere from 3 to 5 days, also affected by climate, inclement weather, complexity and size of the roof.
