What is the Lifespan of a Roof?

Many homeowners want to know one thing when installing a new roof-- how long will it last? This question is not as simple for home roofing professionals to answer as it may seem. A roof's longevity depends on many factors including the materials used, weather conditions, and amount of maintenance performed. Although many of the aspects affecting a roof's longevity are outside for human control, performing regular maintenance and repair is key to ensuring your roof will last as long as possible. Understanding what can damage a roof or lessen its life expectancy is key to maintaining a strong, sturdy home.

What a Roof Does
Roofs keep the elements from damaging the internal structure of your home. Precipitation, ice and wind can severely damage your home if  it is not well protected. The roof's effectiveness and lifespan depend on the installation techniques and materials. Using high quality materials when installing a new roof is the best way to ensure the roof will last for years to come. Although it is tempting to choose roofing materials based on the aesthetics of your home, you should choose the best material for your particular location and roof pitch.

Material Lifespans.
The lifespan of roofs differs greatly depending on the materials used. Asphalt shingles have an 20-30 year life expectancy under the best conditions. Wood shakes usually last for about 14-19 years with proper maintenance. Other materials like slat eand clay tiles will last for five decades if they are properly installed.
