Whether a Metal Roof or a Shingle Roof Costs More: A Comprehensive Analysis

Introduction

Homeowners often debate which roofing material is more cost-effective: a shingle roof or a metal roof. The choice typically depends on several factors including the type of shingles, roof complexity, location, and homeowner’s responsibilities. In this article, we explore the additional costs associated with each roofing type, particularly for a townhouse scenario, and provide insights based on expert knowledge.

The Common Misunderstanding

Many homeowners mistakenly think that a shingle roof is always cheaper than a metal roof. However, this is not always accurate. For instance, a typical asphalt shingle roof is rated for 25 years, while a steel roof can offer a lifespan of up to 100 years. This significantly increases the overall value and cost-effectiveness of a metal roof.

Scenario and Key Issues

The question revolves around a townhouse in a row of attached dwellings without an HOA. In such a scenario, the key issue is the need for waterproofing the joint between the shingles and metal roof. This addition can lead to increased costs. Other considerations include dealing with additional runoff, changing the look of the row of dwellings, and the overall aesthetic impact of the building.

Material Costs and Variations

Choosing the right metal roof is crucial. A 29 gauge metal is generally not recommended as it does not meet the requirements for a Class 4 impact-resistant insurance discount. Instead, a minimum of 26 gauge should be used. For commercial buildings, 24 gauge is common, while 22 gauge can be suitable for residential use. These variations can significantly impact the cost. For instance, a laminate shingle might cost around $250 per square, whereas a U or R panel can cost $400 for galvalume and $440 for painted metal. Standing seam roofs, known for their durability, start at around $550 per square.

Labor and Installation Costs

The difference in labor costs is another key factor. Generally, the cost difference between shingles and metal, considering factors like valleys, ridges, and hips, is around 60 percent more for metal. While shingles might be cheaper when installed, the additional labor costs for metal make it more expensive. The final cost also varies based on local labor rates and the complexity of the roofline.

Comparative Analysis and Value

A premium metal roof with a Kynar finish on galvalume, priced at $1.35 per square foot, costs more than the approximately $66 per 100 square feet for shingles. However, the labor cost for installing shingles can be higher, particularly for complex roofs. Additionally, a shingle roof might be 25 percent cheaper to install, but a metal roof often comes with long-term advantages. For example, it offers a 40 year warranty, higher reflectivity reducing attic heat gain, and increased wind and fire resistance, which can lead to reduced insurance rates.

Total, the net cost of a metal roof is often higher initially, but the long-term benefits can make it a better investment. Shingles might be cheaper upfront, but the return on investment from a metal roof is higher, especially considering its durability and energy efficiency.

Final Thoughts

Homeowners should weigh both the initial cost and long-term benefits when deciding between a metal roof and a shingle roof. While shingles might be more affordable in the short term, the increased durability and cost savings from a metal roof make it a more financially savvy choice over the long term.
