Roof Lifespan Considerations: How Often Do Roofs Need to be Replaced?

Roof Lifespan Considerations: How Often Do Roofs Need to be Replaced?

How long should a residential roof last? Fifteen years? Twenty, 30, or more? Roof lifespan is considerably affected by the material used to manufacture it. Certain roofing materials will naturally provide shorter or longer longevity than other types. Replacing a roof is a significant investment. When evaluating different alternatives, a residential homeowner should consider a roof’s expected lifespan.

8 Factors Impacting A Residential Roof’s Lifespan

A new residential roofing system will provide years of worry-free enjoyment. However, several factors are worth noting when questioning how long a roof will last.

A roofing system that breathes properly can prolong a roof’s lifespan. Inadequate ventilation leads to too much heat buildup in the attic and roof areas. Excess moisture can accelerate the degradation of roofing materials.

Today, many modern roofing systems are designed to be low-maintenance or maintenance-free. However, the lack of routine upkeep and performing roof repairs causes premature deterioration of roofing materials.

The long-range effects of persistent solar exposure (UV radiation) can harm your roof’s health and longevity. Excess heat buildup in the attic and roof may hasten the erosion of roofing materials unless they have a special UV-resistant coating.

Regardless of the roofing product’s quality, a roofing system’s performance depends, to some extent, on the weather. A roof in a location subject to weather extremes could age prematurely.

An improperly or underinsulated roof and attic causes a home to experience inconsistent indoor humidity levels and temperatures. Consequently, the roofing system may experience excess moisture and heat buildup, leading to early deterioration.

Reputable roofing professionals understand that the roofing material selected plays a critical role in the performance and longevity of a roofing system. On average, a three-tab shingle will last about 50% as long as an architectural shingle.

A steeper roof allows water to run off much more efficiently than a low-sloped or flat roof. Standing water tends to expedite the erosion process of a roofing material.

Not all roofing installers are alike. Some roofers know the intricate techniques that maximize a roofing system’s performance. Others lack that expertise or “cut corners” to complete a job quickly. Only hire a roofer dedicated to thoroughness.

The Expected Lifespan Of A Residential Roof

At Yellowhammer Roofing, we primarily install Owens Corning asphalt shingles or metal roofing. Although we can utilize other roofing materials, most homeowners choose either asphalt shingles or metal roofing because of their familiarity, availability, aesthetic qualities, performance, and durability.

Asphalt Shingles Longevity

Asphalt shingle roof

Owens Corning is the leading global manufacturer of asphalt roofing shingles. More homeowners turn to Owens Corning than any other roofing supplier because they trust its roofing products to deliver quality and reliability. No matter what option you choose, Owens Corning asphalt shingles provide exceptional, long-lasting results.

Owens Corning produces the Duration Series of high-performance architectural roofing shingles. On average, these shingles offer a 25 to 35-year life expectancy. In many cases, these resilient shingles last longer. Owens Corning proudly backs up its Duration Series shingles with warranties that range from 40 to 50 years.

Owens Corning continues to manufacture its three-tab Supreme Series shingles for more budget-conscious homeowners. They are the standard, smart alternative for balancing wind and weather resistance with added value. Homeowners can access a limited 25-year warranty with this brand.

Metal Roofing Longevity

Metal roof lifespan is between 40 and 70 years. In some instances, depending on the alloy involved, metal is known to last over 100 years. Steel, aluminum, and tin each have an expected lifespan of 40 to 60 years before requiring replacement. Zinc and copper roofing remain solid as much as 60 to 100 years, or more.

Several crucial factors affect metal roof longevity. Basic installation mistakes can shorten a metal roof’s lifespan. Although metal roofing requires minimal maintenance, a routine inspection should be performed to identify potential issues. Also, environmental conditions can affect a metal roof’s lifespan.

Most metal roofing installers will encourage homeowners to select a steeper sloped metal roof. A low-sloped or flat metal roof can lead to pooling water and ice, which may cause premature deterioration of the underlying roofing material. A steeply sloped metal roof will allow rain and snow to slide off the roof quickly.
