How Long Can You Reasonably Expect Your Roof to Last?
Whether you are building a new home or purchasing a home that’s been around for a while, one of the important questions homeowners want to know is, “how long will my roof last.” There are many factors that impact the longevity of your roof … from materials to climate, and roof installation to maintenance. We’ll give you some things to think about in this installment of our roofing blog!
Numerous factors play a part in the lifespan of your roof, let us help you sort them out.
A big consideration is roofing material
With each type of roofing material there are various grades from low to high quality. Obviously a lower quality, lower cost product will typically lead to more repairs and a shorter life expectancy than a superior product. An experienced roofing professional can help you decide what is best for your home and give you insights into the quality and cost considerations.
When you’re looking at materials, don’t forget to talk about underlayment, a waterproofing layer that protects your home if the exterior surface is damaged. Underlayment prevents moisture and mold buildup so your materials are protected from rot.
Climate plays a part in longevity
Severe weather and sun exposure are factors that play a big part in roof lifespan. In areas with severe and fluctuating temperatures, along with strong storms, the threat to your roof health is major causing cracks in shingles or more drastically, pulling shingles off completely.
Wind, hail and winter storms can leave divots in your roof, compromise the protective granules and leave your home with leaks and/or mold. Trees scraping on the roof and buildup in the gutters are also problematic.
Another consideration is the color of roof you choose. In very hot, sunny areas, lighter materials absorb less heat and reduce wear from overheating.
Ventilation and maintenance are key
Appropriate ventilation is a key to roof longevity. If the roof can maintain a consistent temperature, there is less likelihood of problems from freezing weather and overheating.
Periodic maintenance by a roofing professional can ensure adequate ventilation, as well as identification of any components that have been damaged. Getting a timely repair can mean years in the lifetime of your roof.
Wormanship on installation
Yes, installation can affect the lifespan of your roof! When selecting a roofing contractor, check their qualifications, reviews, and make sure they have appropriate insurance and liability coverage. Choosing the right experienced, licensed pro will help ensure your home health.
HOW LONG DOES THE AVERAGE ROOF LAST IF INSTALLED AND MAINTAINED PROPERLY?
The answer is anywhere from 15 to 50 years, or even longer, depending on the quality and type of material chosen.
Common three-tab asphalt singles are a budget-friendly options, but have one of the lower life spans of 15 to 20 years. Wood shingles tend to last a bit longer, but require maintenance to last up to 30 years. A quality metal roof can protect your home for over 50 years, while architectural asphalt shingles (a thicker, more durable asphalt) can last almost as long. Concrete or clay tiles are durable for over 50 years and slate tiles have the longest average lifespan of well over 50 and sometimes up to 100 years.
Your roofing professional will explain all the options, their life expectancy and price as you make your decisions.
