When Does a Metal Roof Make Sense? What Homeowners Should Consider

There is no single “best” roofing material.

Both asphalt and metal systems can perform exceptionally well in South Carolina when properly designed and installed. The key is choosing the option that fits your home, your climate, and your long-term plans.

Metal roofing has become increasingly popular in our area. We see it on barns, shading lake docks and waterfront structures, and of course on houses.

But when does metal truly make sense?

Understanding how metal compares to asphalt helps homeowners make informed decisions — not just react to trends or price differences.

Asphalt shingles rely on layered, overlapping installation to shed water as part of a complete roofing system.

Metal roofing uses larger panels or interlocking sections that channel water quickly off the roof. There are fewer seams, but installation precision becomes especially important.

Both materials can perform very well — they simply manage water differently.

Architectural asphalt roofs often last 25–30 years depending on installation and climate. Metal roofs can last 40–70 years or more.

Metal typically costs more upfront, but some homeowners prefer fewer future replacements. Others choose asphalt because it balances performance and initial investment.

The right choice depends on how you view long-term value.

Metal reflects more solar radiation than traditional asphalt shingles, which can help reduce heat absorption.

However, ventilation remains critical regardless of material. In South Carolina’s climate, airflow and attic design matter just as much as surface material.

Material and ventilation should always be considered together.

Many assume metal roofs are much louder in the rain.

When installed over solid decking with proper insulation, residential metal roofs are not dramatically louder than asphalt systems. Insulation and structure influence sound more than the roofing surface itself.

A metal roof may be a strong option if:

• You plan to stay long-term
• You value durability
• Your home’s structure suits metal
• You prefer its appearance

It may be less practical if:

• You expect to sell soon
• The higher upfront cost outweighs long-term benefit
• The structure or design does not align

There is no universal answer — only the option that aligns with your home, your goals, and your long-term plans.
