Can metal roofing be installed horizontally?

When considering metal roofing, homeowners and commercial property owners often question whether they can install metal roofing horizontally.

Metal roofing has gained popularity over the years due to various reasons. Traditionally, metal roofs are installed vertically, following the natural flow of rainfall and weather elements.

In this blog, we will explore the possibility of horizontal installation for metal roofing. We will delve into the advantages, case study, disadvantages, who can do your installation, and more. 

So, let's dive in and uncover the secrets and possibilities of installing metal roofing horizontally!
What Is Metal Roofing?  It's a roofing material consisting of sheets of metal. There are various types of metal roofing, such as:

• Steel - it's affordable, durable, and easy to install. Available in finishes such as galvanized, galvalume, and painted.
• Aluminum - Lightweight and corrosion-resistant, making it ideal for coastal areas. More costly but has a longer lifespan.
• Copper - A premium and expensive option with a unique look that develops a patina over time. Highly durable and can last up to 100 years.
• Zinc - Versatile and long-lasting, commonly used in architectural applications. Self-healing and naturally resists corrosion.

Typically, manufacturers make metal roofs out of corrugated sheet metal or rolled sheet metal. These sheets have a ribbed pattern that breaks up the wind and safeguards the underlying structure. 
So, Can Metal Roofing Be Installed Horizontally? Yes, it is possible to install metal roofing horizontally. However, the slope of the roof should be very low or completely flat. 

This installation is commonly used in areas without protection from surrounding structures such as walls or chimneys. For instance, patios and porches are often covered with horizontal metal roofs. 
However, it's crucial to keep in mind certain considerations and guidelines when installing metal roofing horizontally. The horizontal lap joints need to be at least 12 inches long, and proper water shedding and structural integrity are essential. 

The building structure must support horizontal installation. Also, ensure a well-designed drainage system to prevent water buildup and maintain the roof's durability.

Factors to Consider for Horizontal Metal Roof Installation
When considering horizontal metal roof installation, certain factors should be carefully evaluated. They include the following:

1. Roof Pitch
The pitch of the roof plays a crucial role in determining the suitability of horizontal metal roofing installation. A low-pitched roof may not be suitable for horizontal installation because it can result in water accumulation or potential leaks. 
Therefore, consult with a professional roofing contractor, like Motor City Roofers, to assess the feasibility based on your roof's pitch.

2. Weather Conditions
Specific weather conditions impact the performance of horizontal metal roofs, despite metal roofing's durability. For instance, heavy rain, snow, or strong winds may have a greater effect on horizontally installed roofing. 

Consider the climate and weather patterns in the Detroit, Michigan, area when deciding on the installation method to ensure optimal performance.

3. Aesthetic Considerations
Installing a horizontal metal roof can provide a unique and modern look, enhancing the overall design and visual appeal of a property. Contemporary or industrial-style buildings may find it particularly suitable. 
However, it is essential to consider how the horizontal lines will integrate with the existing architecture to ensure a cohesive and pleasing aesthetic.

Pros of Horizontal Metal Roof Installation

• Aesthetic appeal. Horizontal metal roofing provides a modern, unique look that complements industrial or contemporary architecture. It's perfect for those looking for a distinctive design to achieve their desired vision.

Cons

• Water drainage. The horizontal installation raises concerns for proper water drainage, as it may allow for water pooling and leakage if there are insufficient gaps between the panels or inadequate sloping.
• Potential for leaks. You need to pay attention to detail during installation is necessary to prevent potential leaks, which may occur from mishandling or panel gaps.
• Limited suitability. The horizontal orientation of metal roofs may not be ideal for buildings in high-rain or snowfall areas, threatening water retention and subsequent damage.  Although traditional vertical metal roofing installation is the most common practice, homeowners can opt to install metal roofing horizontally for an attractive aesthetic that suits specific architectural designs or personal preferences.
