Roofs are a major investment for a property. Roofs cost a lot of money to install, and it’s important to understand all the factors that play into the lifespan of a roof. If you’re looking to replace your roof, there are several factors that play into the average lifespan of a roof. From material type to even the color of your roof, it all impacts how long your roof will last. Here are some factors that contribute to the longevity of your roof.
Material type
Most roofs last between 25 and 50 years, but it can depend on many different factors. One of the key elements contributing to the average lifespan of a roof is the type of material used on the roof.
- Metal Roofs: This is an excellent choice for longevity as these roofs can last between 50 and 80 years. With proper maintenance, they can last even longer.
- Asphalt Roofs: Most asphalt roofs last between 20 and 30 years. This is also one of the most common materials used in roofing.
- Wood Shakes: These roofs generally last between 20 and 40 years, depending on the quality of wood and materials, and the climate.
- Rubber Shingles: Rubber shingles are excellent for the eco-conscious consumer. This type of roof can last an estimated 30 years and is easy to repair and install.
- Clay and Concrete Tiles: This is a great option for those who are looking for a long-lasting roof. The average lifespan of this roof is roughly 50 years. And even better, they are fire and insect resistant.
- Slate: Slate is the longest lasting roof and is a heavy duty, premium material. This type of roof can last up to a century.
Slope
Pitch of roof impacts drainage. Poor drainage can involve more frequent roof repairs or replacement. Flat roofs and roofs with low slopes should be more careful to check for water damage, which could lead to mold or fungus growth. Water accumulation can also contribute to roof leaks as well.
Ventilation
Ventilation is crucial to your roof health and proper ventilation can go a long way to ensure your roof is in good repair. Poor ventilation can contribute to your roof overheating or freezing, leading to roof leaks. However, proper ventilation can also make your home or property more energy efficient, costing you less in the long run.
Weather & Elements
The climate and sun exposure to your roof plays a large role in the average lifespan of your roof. By choosing durable options, you limit the impact from those elements. However, conditions such as wind, hail, tornados and other storms can still damage your roof. This is where routine roof inspection services come into play for preventative maintenance.
Quality of Installation
When considering a roof replacement service, it is important to review the qualifications of the contractor conducting the replacement. Other things to consider include whether the contractor has proper insurance and liability coverage as well as their reviews. A bad roofing job can decrease the lifespan of your roof drastically, and no one wants to pay for bad workmanship. Ensuring that the contractor is qualified can go a long way to increasing the lifespan of your roof.
Routine Maintenance
Occasional roof maintenance extends the lifespan of your roof. Roofing inspections can detect any damage that may need a roof repair or other warning signs that a replacement is necessary. Many contractors suggest getting annual roof inspections, and more frequently if you experience storm damage.
Quality of Materials
Another factor contributing to the average lifespan of a roof is the quality of the materials used. Like most things, there are both high- and low-quality materials. A good contractor will suggest quality materials and explain the impact on roof longevity. Low quality materials often lead to more frequent roof repairs and a shorter lifespan, costing more money overtime.
Color of Materials
In some instances, the color of the shingles can impact your roof’s life expectancy. Lighter materials are suggested for warmer climates as they absorb less heat than dark materials. Overheating shingles also experience more wear, contributing to worse ventilation.
Underlayment
Underlayment is another major factor in the longevity of your roof. Underlayment offers a layer of waterproof protection in case the exterior roof gets damaged. It also prevents moisture build up leading to mold and prevents the roofing materials from rotting.
When to Replace Your Roof
Regardless of the average lifespan of each roof type, staying up to date on routine inspections can keep you informed of your roof’s health. There are several warning signs to keep an eye out for including:
- Leaks and water damage
- Pest infestations
- Visible damage to your roof and exterior
- Discoloration of ceilings
- Damage to roofing materials
Improving the Lifespan of Your Roof
Proactive maintenance goes a long way to ensure your roof can withstand the test of time. While an annual inspection is ideal, some companies recommend quarterly inspections as each season brings different issues. Spring and summer often bring storms, wind and hail. Fall brings extra debris, requiring routine gutter cleaning to avoid roof damage. Winter is the time to tell if ventilation is an issue. When ventilation is inefficient, ice dams will build up along your roofline or cause leaking in your home. For flat roofs, it’s crucial to regularly ensure the drainage is effective and there’s no build up on the roof.
Final Thoughts
If your roof is nearing the end of its life expectancy, begin planning and saving. Consider contacting a roof replacement service to discuss replacement options ahead of time. This way, you’ll be prepared and educated on what to expect when it comes time to replace your roof.
