Factors that Impact the Average Lifespan of Your Roof 

Type of Materials 

The type of materials you choose for your roof can have a big impact on both the look and the function of your home. For example, shingles made of asphalt are a popular choice because they are durable and relatively inexpensive. However, they don’t offer much in the way of insulation, so if you live in an area with extreme temperatures, you may want to consider another option. Metal roofs are becoming increasingly popular because they are energy-efficient and long-lasting. But if you live in an area with high winds, metal roofs can be susceptible to damage. Tile roofs are another option to consider. They are beautiful and durable, but they can be very heavy, so make sure your home’s structure can support the weight. No matter what type of material you choose for your roof, make sure it is installed by a professional to ensure it will function properly for years to come.

Quality of Materials

Using inferior materials will result in a shorter lifespan for your roof, and it will also be more susceptible to damage from weather and other elements. When you are choosing materials for your roof, be sure to select products that are designed to withstand the rigors of the outdoors. Look for products that are made from high-quality materials and that have been tested to stand up to the elements. Choosing the right materials for your roof will help to ensure that your roof lasts for many years to come.


The underlayment is a layer of material that is installed between the roof deck and the shingles. It acts as a barrier, protecting the roof deck from moisture and rot. It also helps to prevent wind-driven rain from seeping into the house. without an underlayment, a roof would not be able to withstand the elements for very long. That’s why it’s so important to make sure that your underlayment is in good condition. If you’re not sure whether or not your underlayment needs to be replaced, it’s always best to consult with a professional. They will be able to inspect your roof and give you an accurate assessment of its condition.

The Workmanship of Installation

The workmanship of installation is also what guarantees a lasting roof. The first step is a site survey to ensure your home can support the weight of the roofing materials. Then, the roofing team will remove the old roofing material and install new sheathing and flashing. Once the new roof is in place, they’ll install drip edge, valve, and cap flashings.

The Slope of a Roof

Lasting roofs need the right slope to ensure that water and debris don’t pool on the surface of the roof. The slope of a roof is determined by the angle of the rafters. For most homes, a 4:12 pitch is recommended. This means that for every 12 inches horizontally, the roof will rise 4 inches vertically. While this may not seem like much of a slope, it’s enough to ensure that water will run off the roof quickly.


As any roofing contractor will tell you, proper ventilation is essential for keeping a roof in good condition. Without adequate airflow, heat and moisture can build up inside the attic, leading to premature deterioration of the shingles and other components. In addition, poor ventilation can contribute to the formation of ice dams in cold weather, putting even more stress on the roof. That’s why it’s important to make sure that your attic is properly ventilated. If you’re not sure how to do this yourself, hire a professional roofer to assess the situation and make recommendations. By taking these steps, you can help ensure that your roof will last for many years to come.

Different Roof Types and How Long They Last 

Asphalt Shingles 

Asphalt shingles are a type of roofing material made from fiberglass or organic materials (such as paper or wood) that are coated with asphalt and typically embedded with mineral granules.

When properly installed, asphalt shingles can provide years of protection for your home and help to keep your family safe.

Architectural shingles

In addition, the shingles are available in a variety of colors and styles, making it easy to find a look that fits your home.
