Roofs are synonymous to life support for any commercial or residential property. Homeowners or commercial property owners invest in new roof installations as it extends the lifespan of a roof. The need for repairs and replacements decrease when the roof is well-maintained. There are, however, certain factors that determine the life expectancy of a roofing system. The blog post discusses a few factors that govern the lifespan of any roofing system.
1. Roofing Material Type
Roofing materials have different life spans which determine how long a new roof installation is going to last. Choosing the right roofing material is the first step towards the increasing the lifespan of any roof. Here are details of the most widely used roofing materials along with their average life expectancy.
Asphalt Shingles- 15 to 18 years
Laminate Shingles- 23 to 30 years
EPDM- 10 to 16 years
Tile- More than 50 years
Metal Roofs- 30 to 45 years
The roof pitch defines the steepness of inclination and the ability of the roof in draining off water and snow to prevent seepage and water leaks. A high pitched roof tends to perform better in the long run as they dry up fast and prevent the saturation of roofing material. When a roof is resistant to water damage, you can expect a steep increase in its life expectancy.
The color of a roof can greatly affect its lifespan. Dark roof colors tend to absorb more heat which may lead to breaking, cracking or have some other deteriorating effects on the roofing material. Light hues reflect heat effectively and extend the lifespan of the roofs.
4. Insulation and Ventilation
The role of a roofing system is not limited to moisture control and extends beyond. An improper insulation and ventilation may cause a buildup of warm, moist air leading to ice dam formation in winters, mold and mildew growth and even rotting of the wood decking.
Heat has a significant impact on any roofing system, especially asphalt roofs as intense exposure to the sun can cause premature aging and crack the shingles. Opt for a green roof during the installation or a cool roof coating to protect the roofing system from heat damage.
The Way Forward
New roof installations can last for years, if you take care of the above factors and also give due importance to frequent inspections and maintenance. Roofs often face the brunt of rough weather and external elements that lead to aging and serious damage, incurring costly repairs. Many people try a DIY maintenance that does more harm than good to their roofing system. Roofing contractors possess the expertise to perform and maintain the new roof installations to ensure you get the maximum protection and value from your roofs.
