Metal roofing has gained significant popularity in the residential roofing industry, with some reports even suggesting that it will surpass asphalt roofing as the most popular material. As homeowners consider this investment, one of the most pressing questions revolves around the lifespan of a metal roof. So, how long does a metal roof last? In this article, we will provide you with comprehensive information about the longevity of metal roofs and the factors that can impact their lifespan.
Metal Roof Lifespan: How Long Does a Metal Roof Last?
The lifespan of a metal roof depends on various factors, including the type of metal roofing system and proper installation. Generally, a metal roof can last around 30 years. However, it’s important to delve deeper into two specific types of metal roofing systems: standing seam and screw down panels.
How Long Does a Standing Seam Metal Roof Last?
A standing seam metal roof is a series of interlocked panels that can freely expand and contract as the metal heats up and cools down. When properly installed with adequate attic ventilation, a standing seam metal roof can last at least 30 years. In ideal conditions, it can even exceed 50 years.
The long lifespan of a standing seam metal roof is attributed to the Kynar 500 painted finish, which not only protects the roof from the elements but also prevents color fading. This durable painted finish is applied through a patented process and comes with a 30-year warranty. Even after the warranty period ends, the Kynar 500 finish continues to maintain its integrity, allowing standing seam metal roofs to last for several decades.
How Long Does a Screw Down Panel Metal Roof Last?
A screw down panel, also known as an exposed fastener metal roof, is installed by screwing down the panels with exposed fasteners. Unlike standing seam roofs, screw down panel roofs lack the ability to naturally expand and contract. Consequently, proper installation and maintenance are crucial for their longevity.
With regular maintenance, a screw down metal roof can last up to 30 years. However, without proper care, its lifespan may be limited to around 20 years. It is important to note that screw down panels do not come with the Kynar 500 painted finish, and the warranty for the paint used on the steel or aluminum panels varies.
Factors Affecting the Lifespan of a Metal Roof
While proper installation is essential for maximizing the lifespan of any metal roof, there are several other factors that can significantly impact its longevity. Understanding these factors will help you make informed decisions and ensure the longevity of your metal roof and answer the question, how long does a metal roof last.
1. Protecting the Painted Finish during Installation
During the installation process, it is crucial to handle the metal panels with care to protect the painted finish. Scratches or damage to the finish can expose the underlying metal to moisture and cause rusting. This can compromise the lifespan and performance of the metal roof. To prevent this, it is recommended to clean the roof daily during the installation process and avoid any cuts or shavings that could lead to rusting overnight.
To ensure the proper installation of your metal roof and safeguard the painted finish, it is advisable to hire a local roofing contractor with experience in metal roof installation. Their expertise will help protect your investment and ensure the longevity of your metal roof.
2. Weather Conditions in Your Area
The climate and weather conditions in your area play a significant role in the wear and tear experienced by your metal roof. Extreme weather conditions, such as heavy snowfall or hail, can weaken the integrity and finish of the metal panels, leading to a shorter lifespan. Similarly, regions with high temperatures can affect the expansion and contraction capabilities of screw down metal roofs, potentially reducing their longevity.
While you have no control over the weather, it is important to discuss with your roofing contractor how the local climate might impact the lifespan of your metal roof. Their insights and recommendations will help you make informed decisions and ensure the durability of your roof in the face of regional weather conditions.
3. Maintenance of the Metal Roof
Regular maintenance is essential for maximizing the lifespan of any type of roof, including metal roofs. However, the extent and type of maintenance required differ between standing seam and screw down panel metal roofs.
A standing seam metal roof generally requires minimal maintenance, with the exception of checking around penetrations, such as vent pipes, for any potential issues. Clearing debris and inspecting the roof annually will help identify and address any maintenance needs in a timely manner.
In contrast, screw down panel metal roofs with exposed fasteners require more maintenance. Over time, the pressure caused by the lack of expansion and contraction can cause the holes in the washers to enlarge, leading to leaks. It is essential to replace the screws every 5–10 years, as failing to do so can result in costly problems and potential roof damage during strong storms.
