Expert insights to help you make an informed decision about selecting the best metal roofing options for your home or project.

Metal roofing is a long-term investment that offers durability, energy efficiency and aesthetic appeal. ASC Building Products, a leading manufacturer in the western U.S., provides insight into the essentials of metal roofing to help homeowners and builders make informed decisions.

Understanding metal roofing basics

Metal roofing comes in two primary types: concealed fastener (standing seam) and exposed fastener (thru-fastened) systems.

Concealed fastener (standing seam)

Standing seam roofing is the preferred choice for residential projects due to its sleek appearance, superior weather resistance and lower maintenance requirements. It features a raised seam where panels connect, offering a streamlined, modern look.

For many residential projects, a snap interlocking panel offers an ideal balance of durability, ease of installation and cost-effectiveness. Mechanically seamed panels, which are more commonly used in commercial settings and regions with extreme weather, provide enhanced security and stability. Mechanically seamed panels, often used for commercial and extreme weather conditions, provide additional security.

Exposed fastener (thru fastened)

Exposed fastener roofing is more economical and easier to install, making it ideal for agricultural buildings, sheds and DIY projects. While these panels offer broader coverage and quicker installation, their fasteners are visible and may require periodic maintenance to ensure longevity.

Colors, coatings and performance factors

One of the standout features of metal roofing is its extensive color range. Light-colored metal roofs reflect more heat, enhancing energy efficiency. Paint systems play a crucial role in durability, with options ranging from Polyester (Good), Silicon Modified Polyester (Better), to PVDF (Best).

Additionally, Solar Reflectance Index (SRI) ratings help homeowners assess a color’s ability to reflect heat, contributing to lower cooling costs. Meanwhile, metallic coatings like ZINCALUME® and Galvalume provide superior corrosion resistance, ensuring metal roofs last decades longer than traditional roofing materials.

Key considerations before installation

• Gauge & material: Metal thickness impacts durability and cost. Residential projects commonly use 26-gauge steel, while coastal areas may require aluminum for superior corrosion resistance.
• Lead times: Unlike traditional shingles, metal roofing panels are made to order (MTO) for precise lengths.
• Warranties: Metal roofing comes with extensive warranties, covering substrate integrity, paint performance and weather resistance.
• Trims & accessories: Flashings, fasteners and sealants play a critical role in aesthetics and longevity.

Making an informed decision

Choosing the right metal roof involves weighing factors such as cost, design complexity and long-term benefits. While metal roofing has a higher upfront cost than asphalt shingles, it boasts 3-4 times the lifespan, making it a wise investment for homeowners looking for sustainability and resilience.

The longevity and ability of a roof to withstand the elements largely depend on the quality of its installation. Choosing a skilled and experienced contractor is essential for achieving the best results. Working with an experienced contractor ensures the best results.

For those considering solar panels, metal roofing offers a significant advantage. Metal roofing provides a long-term benefit for those considering solar panels, as it generally has a longer lifespan than the panels themselves. This reduces the need for re-roofing underneath the solar installation over time.
