How Long Can Your Roof Last?

The roof is a crucial structural part of your home. It protects you, your family, and your belongings from the elements. When choosing the roofing material for your home, it is important to have something that lasts as long as possible and offers reliable protection. So, how long do roofs last?

While the average service life of a roof is 30 years, different materials have different lifespan. Find out how long different types of roofs last.

Asphalt Shingles

According to most roofing companies, their asphalt shingle installations can last up to 30 years. The actual numbers vary based on different factors. These factors are as follows:

• Type: There are three different types of asphalt shingles. These are Dimensional, 3-Tab, and Premium shingles. Dimensional shingles can last up to 28 years while 3-Tab asphalt shingles have a service life of 22 years. Premium shingles can protect your home for up to 30 years.
• Workmanship: Choosing a roofer with more experience in providing quality installation can help your roof last longer.
• Ventilation: When your attic is properly ventilated it can help preserve your roof by reducing heat and moisture buildup.
• Maintenance: Regular inspection and maintenance can have a big impact on the longevity of your asphalt roof. Conduct a visual inspection of your roof every year and get a professional inspection every five years.

The weather condition in your region also affects your roof’s service life.

Wood Shake Roofs

Wood shake roofs are valued for their aesthetic appeal and longevity. When well-maintained, these roofs can last up to 50 years. However, such a service life applies to roofs made of vertical-grain cedar shingles. If your roof is made of both flat and vertical-grain shingles, it will be more affordable but not last as long.

Your wood shake roof can withstand winds up to 120 mph. Still, you must keep the following things in mind to ensure you get the most out of your roof:

• Proper Installation: When installed properly, these roofs last longer. This means choosing the right type, ensuring proper spacing, and installing correctly.
• Debris Removal: Cedar shake roofs are prone to mold and algae growth when dirt buildup occurs. It is important to prevent dirt from accumulating on wood shake roofs.
• Regular Maintenance: It is recommended to check your roof before the rainy season and winter to clear any organic material.
• Fixed Damages: While cedar wood shakes are quite durable, long-term exposure to dampness can make them weak. So, you should have your roof cleaned regularly and ensure any damages get fixed in time.

Further, it is recommended to avoid power washing your wood shake roof.

Metal Roofs

When it comes to metal roofs, an average homeowner can expect their roofing to last from 40 years to 70 years. Interestingly, with proper maintenance, some metal roofs can last a century.

The different factors affecting the lifespan of your metal roof are as follows:

• Roof Type: While aluminum roofs are recorded to last 40 to 70 years, zinc or zinc-aluminum-coated steel roofs have been found to last 30 to 50 years. Both copper and zinc roofs are known to last up to 100 years when properly maintained.
• Installation: Properly sealing seams and joints and avoiding exposed fasteners can eliminate the chances of premature deterioration and leaks.
• Protective Coating: Having your metal roof coated with protecting layers can increase its resistance to UV radiation, moisture, and corrosion.
• Slope: Roofs with higher pitches allow water and debris to flow off. This helps reduce water damage and increase the roof’s life.
• Maintenance: All metal roofs require regular inspection and cleaning. Addressing issues such as loose panels, debris accumulation, and water pooling in time can help your roof last as long as possible.

Now that you know how long different roofs last, you can make the right choice for your home. Besides, the above-mentioned information can also provide insights into what needs to be done to make your roof last long.
