San Antonio Roofing: Article About Factors That Affect The Roof's Lifespan
The roof is one of the most important elements of any home. It keeps the house's structure safe from damages and protects occupants during bad weather or extreme heat. However, roofs will need to be replaced eventually. Reroofing is generally an expensive undertaking. A San Antonio roofing contractor may simply recommend repairs that will help extend the lifespan of the roof and delay the need for extensive reroofing projects.
One of the biggest factors that contributes to the roof's lifespan is its material. For example, asphalt shingles are expected to last about 15 to 18 years depending on the quality of the materials. Metal roofing can last anywhere from 30 to 45 years. Although slate or tile roofing is expected to last about 50 years, these types of roofs can last one hundred years or more when cared for properly.
The roof color and the exposure to the sun also play roles in the roof's lifespan. Intense heat can break down the outer roof materials over time. Darker roofs, such as asphalt roofs or rubber roofs, soak in more sunlight, causing degradation to occur at a much faster pace.

Homeowners who live in hot or humid climates may wish to choose light colored roofs to slow down the degradation process.
While the roof's ventilation system controls the amount of moisture that enters into the attic, it also allows heated air to escape from the attic. This helps to keep the roof much cooler, especially in wet or hot climates. The cooler the roof, the less heat damage it will sustain. A properly ventilated roof will last for a much longer period of time.
Finally, the age of the roof when the home was purchased is a big factor in determining the remaining lifespan of the roof. If an asphalt roof was installed on the home 15 years ago, the home will likely need a new roof within the next few years, even if the roof was well maintained. As such, those looking to purchase a new home should always make sure to have the roof inspected. Once the home is purchased, any repairs that may be needed should be taken care of to extend the roof's lifespan for a little while longer.
A roofer should be contacted to ensure that the roof's support systems and materials are in good order. Additionally, a contractor should be scheduled to inspect the roof regularly to keep it in the best condition possible.
