Ask any commercial roofing company and they will say, a well-installed roof can last for a few decades. Asphalt shingles can last for 40 years while metal roofs can last 70 years. But no matter how sturdy roofs are, if they are not maintained properly, then they won’t reach their maximum lifespan.

As a matter of fact, there are certain factors that can affect the lifespan of your roof. It’s important that these factors are seriously considered when building your home or installing a new roofing system. These factors are as follows:

Weather

The weather in your area plays a crucial factor in the lifespan of your roof. There are elements such as rain, hail, snow, and UV rays that can reduce the life expectancy of roofs. This is the reason why you should always pick local contractors when it comes to installing roofing because they know the general weather condition in the area and would suggest materials that would be more resistant to the elements.

Roof Slope

You may not realize it but the slope of your roof also plays a crucial factor in its longevity. The higher the slope of the roof, the more resistant it is to damages. Lower sloped roofs are susceptible to moisture, which means they easily get damaged.

Insulation and Ventilation

Adequate insulation is required so that the heat, moisture, and air won’t build up and affect the roofing material. Poor ventilation, on the other hand, may lead to blistering asphalt shingles and defective wooden roof deck because of condensation and moisture.

Roof Protective Layer

Roofs use different types of protection and whatever protective layer used affects their longevity. Asphalt roofs use a thin level of protection that could adequately increase its lifespan. As for metal roofs, the right choice of paint is essential, as there are certain colors that can retain heat more than others. Too much heat can damage roofs in different ways.

Maintenance

The way you maintain your roof can maximize its lifespan. All roofs need maintenance so that it won’t deteriorate due to the factors listed above. If you just install the roof and neglect it altogether, then it won’t reach the expected time of functionality. Maintenance starts a couple of months after the roof is installed.

Roof Orientation

The direction your roof faces affects its longevity as well. South-facing roofs tend to receive more sunlight than north-facing ones. So if that’s the orientation of your roof, lower are the chances that it will meet its full life expectancy. North-facing homes tend to keep more snow and moisture on the roof. It is important that these roofs are well-insulated and ventilated in order to last long.

To ensure that your roof maximizes its lifespan, it has to be maintained very well. As the roof ages, the higher its maintenance requirement is. Aging roofs need regular repairs and careful monitoring as problems tend to exist more often on these types of roofs. Roofing contractors should provide homeowners a good assessment whether it is advisable to keep on repairing the roof or if it’s time to install an entirely new one.
