How long is a roof good for? In this article, we’re looking to discuss the longevity of a roof.
It’s important to note that several factors will determine the lifespan of your roof. These include roof color, material type, roof maintenance, local climate, roof installation, etc.
How Long Should a Roof Last?
Roofs are essential components of homes and buildings and shield against the elements.
Due to their constant exposure, these structural components will inevitably steadily deteriorate with time. So, how long does a roof last? What’s the average lifespan of your roof?
Average Roof Lifespan
In providing a general answer to the question, roofs last an average of 30 years.
However, the lifespan of your roof will be determined by various conditions, as will be discussed shortly. If you’re planning on buying a new roof, this information will help you choose wisely.
One of the things to know when shopping for a roof is that cheap materials won’t last. It’s best to avoid cutting corners when shopping for your construction materials.
How long does a new roof last?
To provide an in-depth assessment of roof lifespan, we’ll need to consider the different factors impacting longevity.
The Longevity of your Roof will Depend on the Following Factors.
How long are roofs good for?
Having mentioned the average roof’s lifespan, it’s time to identify and discuss the multiple factors determining how long roofs last.
These include roof color, material type, roof maintenance, local climate, roof installation, roof usage, ventilation & insulation, and the roof slope.
Factors affecting roof longevity include periodic inspection & maintenance, material quality, and underlayment. With that said, let’s discuss how each of these impact roof lifespan.
How does roof color affect its lifespan? Specific colors like black are known to be more absorbent of heat. So, it’s only logical that black roofs will absorb more heat than those with lighter colors.
With increased heat absorption comes breakage or melting.
With such a reality, it’s safe to say black roofs are more likely to have a shorter lifespan than roofs with lighter or bright colors.
Standard roof colors include black, dark gray, dark brown, dark green, brown, green, gray, blue, red, white, dark blue, dark green, and charcoal.
Different roof materials have varying life expectancies. For example, those made from metal will last anywhere from 40 to 50 years, while concrete tiles will stay an average of 50 years.
For asphalt shingles, with are pretty standard, the expected lifespan is around 20 years. Wood shingles have an average longevity of 30 to 40 years.
Roofs are made from a variety of materials. Examples include solar tiles, roof gardens, rubber slate, spray-on roofs, and slate.
Others have built-up roofs (BUR), felt underlayment, clay tiles, EPDM rubber, concrete tiles, PVC, asphalt shingles, fleeceBack, TPO, metal roofs, wood shingle or shakes, and modified bitumen roofs.
Like other structural components, maintenance is essential to ensure effective functioning.
The absence of care creates a problem in the sense that issues may arise that may not be urgently addressed. These could deteriorate your roof’s lifespan considerably.
It’s essential to have any issues fixed before it gets worse. The only way to do that is by carrying out frequent maintenance services. Of course, expert maintenance is needed.
Roof technicians will advise on ideal maintenance frequency.
Your local climate plays a significant role in determining the longevity of your roof.
Certain areas are known to experience harsher weather conditions than others. Such conditions include hail, snow, strong winds, and sun intensity.
Harsher climates are likely to affect roof longevity. However, the best way to work around this is by using appropriate roof materials for such climatic conditions.
These will last longer when compared to roofs made from materials that aren’t suitable for your local climate.
Who handles your roof installation? This is important because a messy job can be costly in the long run. In other words, poor installation leads to early deterioration and damage.
This is important because even the best quality roofs are likely to deteriorate faster or have a shorter lifespan when not correctly installed.
Here, the solution is simple. To extend your roof’s lifespan, have an experienced and licensed roofing company handle your installation needs.
These have highly skilled technicians who understand everything there is to know about quality installation.
If you wonder how roof usage impacts longevity, you only need to look at what’s installed on them.
Standard roof installations include solar panels. Heavy panels are likely to have a negative impact in the long run. This shortens the lifespan.
Other conditions like overhanging branches slowly put significant pressure on roofs. It’s essential to have them trimmed off. Clogs and gutters are additional problems that can limit the lifespan of your roof.
Ventilation & Insulation
Is your roof properly ventilated? Every roof type has a ventilation requirement that must be met, failure of which leads to a shortened lifespan.
Excess moisture is arguably the biggest problem with structural components, including roofing. This is likely to lead to rapid deterioration.
How is roof slope a problem? To better understand this factor, you’ll need to consider water drainage.
The hill, pitch, or angle of your roof will determine how fast it drains rainwater and snowmelt. You must ensure your roof has a high slope to help drain water faster.
This helps avoid damage and leaks.
Inspection is a critical requirement that needs to be maintained. Without such inspection, problems are left unattended.
However, your roof’s condition is known with periodic or scheduled inspections. This helps with prompt action or intervention to tackle a problem before it worsens.
As with other structural components, a preference for cheaper materials will eventually cost you a lot in damage as these are known to have shorter lifespans.
Consider using high-quality materials to avoid having your roofs replaced more often than required. These may cost more but are worth the investment.
Underlayment serves as an additional layer of defense against moisture.
This becomes evident when the roof exterior gets damaged. A roof without underlayment protection tends to incur damage a lot faster.
Now you know how long different roof types last. We’ve also included information on factors affecting the lifespan of this essential structural component. This guide will help with a better selection of your roofs.
Also, seeking professional advice is something you should be open to.
