How Long Does a Roof Last in South Carolina

The roof is one of the most important parts of the house. It protects us from harsh weather conditions, ensuring safety. However, all roofing materials have a specific lifespan.

A roof’s lifespan depends on the material and installation quality. A metal roof, for instance, lasts longer than asphalt shingles. Clay tile roofs have the longest lifespan of all.

Generally, a high-quality roof in South Carolina will last for an average of 20 to 50 years, depending on the material. Asphalt shingle roofs are the most common, lasting 10 to 25 years.

Factors Affecting Roof Durability

Contact your roofing contractor to advise you on different ways to choose the right material for your local weather. This is because the climate and roof material as the main factors affecting roof durability. Consider the following too.

Material type and quality

Everyone homeowner wants the best roof replacement material. However, your experience depends on the material type and quality. Metal roofs are different from asphalt roofs in terms of longevity. Whereas an asphalt roof can serve you for 15 years, a metal one can go over 30 years.

The underlayment and other parts of the system

You must check to ensure the underlayment is strong enough before an asphalt roof replacement. It is the same for other roofing materials, as the underlayment determines how long the roof lasts. Heavier slate tile roofs and similar systems require stronger underlayment.  

Quality of installation

Hire the most experienced roofer to replace your roof, and it will last the maximum lifespan. Materials like clay tiles are more challenging, and the last thing you want is to deal with roof leaks too soon. Poor installation is among the biggest threats to roof durability.

Whether conditions

A higher quality roofing material has more tolerance for elements than a lower one, although some materials are just less effective. An asphalt shingle roof offers great protection, but it gets damaged too easily, especially without proper installation. Slate roofs, on the other hand, may offer more tolerance.

Roof’s slope

The slope of your existing roof determines how long it will last. Slopped roofs tend to last longer as they allow water to flow off more easily compared to flat roofs. Consider this carefully when installing a new roof.

Ventilation

If you have asphalt shingles or stone-coated steel tiles, improper ventilation can reduce lifespan. When heat is trapped within the material, it can melt away the adhesive or cause other damages. This can lead to expensive roof repairs that may end up in a full replacement too quickly.

Maintenance and care

Your metal, shingle, or tile slate roof will not last long without proper maintenance. Missing shingles, debris, mold growth, and other issues may adversely affect the roof, forcing a replacement too soon. And that is why regular maintenance is necessary.

Shingles

Many roofing contractors choose shingles because they are easier to work with. But most are not very durable.

Standard asphalt shingle

With standard asphalt shingles, you should start considering a full roof replacement once they hit 10 years. These roofs can last for 10 to 29 years, depending on the factors mentioned above.

Organic asphalt shingles

Organic shingles have a lifespan of 15 to 25 years. If properly installed, these roofs can give you an amazing performance. But they are more demanding in terms of maintenance.

Wood Shingles

Architectural asphalt shingles

 Architectural shingles are among the most durable materials for any roof. They offer better tolerance even under severe storms, making them an excellent choice for South Carolina homes.

Composite shingles

Composite, or sometimes slate shingles, provide a durable layer of protection for many homes. It is a type of roof that performs incredibly in cold and sunny climates. These roofs can easily last for 40 to 50 years when properly installed and maintained.

Metal Roofing

Metal roofs can be extremely durable with a professional installation. Thinner sheets can give you 20 to 25 years, while strong metal can last for over 50 years before they start showing warning signs. Proper maintenance makes a metal roof last even longer.

Commercial Flat Roofs

Commercial roofs are designed to handle extreme weather conditions like high winds and UV rays in the best way possible. They can last for an average of 15 years but with proper maintenance. Common types include:

  • EDPM. This is one of the most common synthetic rubber materials for flat roofs. It’s affordable, easy to install, and can last for 25 to 30 years.
  • PVC. The raw materials in PVC can make your roof last for over 20 years. It has great resistance to UV rays, making it excellent for flat roofs.
  • TPO. This is another great choice for flat roof materials. TPO can last for 15 to 20 years. It’s flexible and less expensive than PVC but strong than EPDM.
  • Spray foam. Spray foam is a solution for many factors that affect roof durability. Its lifespan depends on thickness and coating, plus regular maintenance. The roof can last for over 50 years.
