Pros and Cons of Installing Metal Roofing

It’s important to weigh the pros and cons before you install metal roofing. Luckily, we’ve compiled them all for you!

✅ Pros of a Metal Roof

• Longevity: One of the most significant advantages of a metal roof is its exceptional lifespan. Unlike traditional asphalt shingles that may need replacement every 20-30 years, a well-maintained metal roof can last 50 years or more. Some metal roofing materials, such as steel and aluminum, are known for their resistance to corrosion, making them even more durable.
• Durability: Metal roofs can withstand harsh weather conditions, including heavy rain, snow, hail, and high winds. They are also fire-resistant, reducing the risk of a catastrophic house fire. The strength and resilience of metal make it a reliable choice for regions prone to extreme weather.
• Energy Efficiency: Metal roofs reflect solar heat, helping to maintain a cooler indoor temperature during hot summer months. This reflective quality can lead to lower energy bills by reducing the need for air conditioning. Additionally, many metal roofing systems are designed to be energy-efficient and are eligible for tax credits or rebates.
• Low Maintenance: Metal roofs require minimal maintenance compared to other roofing materials. They do not rot, warp, or crack like wood or asphalt shingles. Regular inspections and occasional cleaning are usually sufficient to keep your metal roof in excellent condition.
• Aesthetics: Modern metal roofing comes in a wide variety of styles, colors, and textures, allowing homeowners to choose a look that complements their home’s architecture and personal taste. Metal roofs can add a sleek and contemporary appearance to any building.

Cons of a Metal Roof

• Initial Cost: One of the primary drawbacks of metal roofing is the higher upfront cost when compared to traditional asphalt shingles. However, it’s essential to consider the long-term savings in maintenance and energy bills.
• Noise: Some people may find metal roofs to be noisier during rain or hailstorms compared to shingle roofs. However, proper insulation and underlayment can help mitigate this issue.
• Installation Complexity: Installing a metal roof requires specific skills and equipment, making it more complex than traditional roofing materials. It’s crucial to hire a professional to ensure proper installation.

7 Steps to Install a Metal Roof

Installing a metal roof is a meticulous process that should be carried out by experienced professionals. Here is an overview of the general steps involved:

1) Inspection and Preparation:

Begin by inspecting the existing roof structure to ensure it can support the weight of a metal roof. If needed, make any necessary repairs or reinforcements. Remove the old roofing materials, including shingles or tiles.

2) Install Roof Decking:

Install a solid roof decking made of plywood or OSB (oriented strand board) over the existing roof structure. This provides a stable and flat surface for the metal roofing panels.

3) Install Underlayment:

Apply a high-quality roofing underlayment to serve as a moisture barrier and protect against leaks. Self-adhering synthetic underlayment is commonly used for metal roofing installations.

4) Flashing and Trim Installation:

Install flashing around roof penetrations, such as chimneys and vents, to prevent water infiltration. Custom metal trim pieces are also installed along the edges of the roof to provide a finished appearance.

5) Roofing Panel Installation:

Begin laying the metal roofing panels, starting from the eaves and working your way up to the ridge. Use appropriate fasteners, such as screws with neoprene washers, to secure the panels to the roof decking. Ensure proper overlap and alignment between panels.

6) Ridge Cap Installation:

Install ridge caps at the peak of the roof to seal and protect the roof’s highest point. Ridge caps are specially designed pieces that provide a finished look and prevent water from entering.

7) Quality Control:

Thoroughly inspect the completed metal roof for any imperfections, loose fasteners, or gaps. Ensure all seams and connections are properly sealed and waterproof.

Why You Should Hire a Professional to Install Metal Roofing

While it might be tempting to install a metal roof yourself to save money, there are several compelling reasons to hire a professional roofing contractor:

• Expertise: Professional roofers have the necessary expertise and experience to ensure a proper and long-lasting installation. They are familiar with the specific requirements of metal roofing systems and can address any challenges that may arise.
• Safety: Roofing can be dangerous work, and professionals are trained in safety protocols to minimize the risk of accidents. They have the right equipment and knowledge to work safely at heights.
• Warranty: Many roofing manufacturers offer warranties on their products, but these warranties often require professional installation to be valid. Hiring a professional ensures that your roof is covered by the manufacturer’s warranty.
• Time and Efficiency: Professional roofers can complete the job efficiently, saving you time and ensuring that your roof is installed correctly the first time. DIY installations can lead to costly mistakes and rework.

The Cost of Installing a Metal Roof

The cost of installing a metal roof can vary widely depending on several factors, including the type of metal material, the complexity of the installation, the size and shape of your roof, and your location. On average, you can expect to pay between $7,000 and $15,000 for a metal roof installation on a standard-sized home.

Here’s a breakdown of cost factors:

• Material Cost: Different metal roofing materials come at varying price points. For example, steel and aluminum are generally more affordable than copper or zinc. The style and profile of the metal panels also affect the cost.
• Labor Cost: Labor costs can make up a significant portion of the total expense. The complexity of the installation and the skill level required can impact labor costs.
• Roof Size and Shape: Larger roofs require more materials and labor, which will increase the overall cost. Complex roof designs with multiple angles and features can also drive up the price.
• Location: The cost of living and regional labor rates can influence the cost of your metal roof installation. Additionally, local building codes and regulations may require specific roofing materials or installation methods, affecting costs.
