The lifespan of a roof depends on several different factors. Two major factors that determine how long a roof will last include the roof type and your location. Moreover, workmanship also plays an important role. Expert Alabama roofers will install the roof professionally, which will ensure the maximum lifespan of the roof.
In this blog, you will learn about the factors that influence the lifespan of a roof. Understanding the factors that determine a roof’s lifespan will help you select the right materials for your roofing project.
1. Roof Material
Different roof materials have different lifespans. Some last for more than five decades while others have to be replaced after a decade or two. According to the National Association of Home Builders, the lifespan of different materials are as follows.
- Slate, Tile, and Copper Roofs: 50 years
- Wood Shake Roofs: 30 years
- Fiber Cement Shingles: 25 years
- Asphalt Shingle Roofs: 20 years.
Additionally, a metal roof has the longest lifespan. With proper care and maintenance, a metal roof made of stainless steel can last as long as a century.
2. Roof Underlayment
The underlayment of a roof can extend the lifespan of a roof. Underlayment is installed beneath the existing roof. It offers an extra layer of protection against rain, snow, and other weather conditions.
No matter what type of roof material you install; an underlayment will protect the roof material from the weather elements. Installing an underlayment will make the roof water-resistant. Homes in Huntsville, AL will greatly benefit from an underlayment that is designed to offer protection against tough weather conditions.
3. Ventilation
Ventilation of a roof can also help in extending its lifespan. Eave vents and ridge vents are important for the proper ventilation of the house. These vents remain invisible and don’t affect the look of the house.
A well-ventilated roof can add years to the roof’s life. Ventilated roofs remain cooler during the winters preventing the snow from melting and ice dam formation. Additionally, a ventilated roof will prevent the attic from getting too warm during the summers. It will also prevent moist on the roof that can rot out the roofing material.
Additional ventilation may be required according to the architectural feature of the roof. You should consult an expert Alabama roofer for proper ventilation of the roof.
