What to Ask Your Contractor Before Building a Metal Roof 

Planning a metal roof installation is an investment that can protect and enhance your home for decades. With many options for materials, styles, colors, and installation techniques, navigating the landscape of metal roofing may feel a little overwhelming, but there are a few simple steps you can follow to get the answers you need. 

Transparent communication and a clear understanding of expectations are the biggest factors for a successful project. As a homeowner, you should ensure you receive a written contract outlining the scope of work, timeline, costs, and warranty terms. It’s also wise to ask about the contractor’s safety protocols and if they handle permits and compliance with local building codes. 

To help you make an informed decision for a successful roofing project, we have provided critical questions every homeowner should ask their contractor before building a metal roof.  

How Long Do Metal Roofs Last on Average?  

Metal roof durability and longevity are often the top priorities homeowners like to know before making their investment. Unlike other traditional roofing materials, like asphalt, which typically lasts 15 to 20 years, metal roofs can last from 50 years to 70 years with proper installation and maintenance.

Where to Start: Finding the Right Contractor  

Customers should ensure the contractor is licensed, insured, and experienced in installing metal roofs. Dive deep into their professional background by reviewing customer testimonials, requesting or contacting references, and viewing their work on projects similar in scope and complexity to yours. 

While independent product research is valuable, engaging directly with contractors can reveal crucial insights into their technical expertise and professional relationships. Look for contractors who demonstrate specialized knowledge of high-quality brands or systems and maintain strong partnerships with reputable suppliers or manufacturers. These professionals have a depth of knowledge that goes beyond installation and can offer recommendations tailored to your needs and home characteristics. 

Attributes to Keep in Mind 

When selecting a metal roofing contractor, reputation and quality of work should stand at the forefront of your decision-making process. Look beyond surface-level factors and seek professionals whose past work demonstrates consistent quality, precision, and technical expertise. A contractor with a solid reputation and proven results will deliver a roof that looks great and performs well.   

Metal roofs require craftsmanship and experience to install, so be sure to look at prior work. Pay attention to how they communicate, their willingness to discuss project specifics, and their portfolio. This will help determine the alignment with your needs and home.  

Factors to Ask Your Contractor About 

Here are a few things to go over with your contractor to help make the right roofing selection. 

• Material Options: Choosing the right metal panel material is important, whether it be steel or aluminum options. Your contractor should explain the specific material and thickness recommendations based on your location, home structure, and long-term performance. 

• Durability: Determine the metal roof’s resistance to weather and corrosion, and overall longevity. What’s the durability in high winds or heavy snow? Ask about coatings like Galvalume or specialized paint systems that extend the roof’s lifespan and enhance its aesthetic appeal. 

• Energy Efficiency: Ask about the energy benefits and solar applications of metal roofs. Does the metal roofing they install have insulative properties? Are there underlayment options that enhance energy performance? 

• Compatibility: Your metal roof should be suitable for the climate and the existing building structure. Ask about the compatibility with your home’s existing insulation and ventilation systems, keeping in mind the potential for thermal expansion and contraction. 

• Aesthetics: Metal roofing offers endless design possibilities. Be sure to discuss color options, panel styles, finish textures, and color-matching capabilities. 

• Cost & Benefits: While the initial investment is higher, metal roofs offer substantial long- term value. Explore cost comparisons, energy savings, maintenance costs, and warranties—weighing not only upfront cost but long-term return on investment. What are the differences between panel styles and materials, and what are the benefits of each? 

Understanding these factors ensures that you can select a product that aligns with your needs and preferences, while maximizing benefits and return on investment. A knowledgeable contractor will guide you through these choices, helping you make an informed decision.  

Determining Warranty Information 

Consumers should understand both material warranties (coverage for defects or deterioration) and workmanship warranties (coverage for installation issues). Key questions to ask your contractor include: 

• What is covered under the warranty and for how long? 

• Are there maintenance requirements to keep the warranty valid? 

• Who honors the warranty—the manufacturer or the contractor? 

• What happens to the warranty if the contractor goes out of business?

Ensuring Proper Insulation 

While metal roofs offer remarkable reflective and cooling properties, a critical component of this system is proper insulation. By asking your contractor questions about insulation methods, materials, and installation techniques, you gain understanding into how your roof reduces costs, minimizes temperature fluctuations, and creates a comfortable environment. 

Understanding Installation Methods 

Understanding the installation of your metal roof is key to maximizing your investment. Ask questions like: 

• What does the roof replacement process look like? 

• Will you be removing the old roof? 

• What specific steps do you take to prepare the roof deck? 

• Do you use underlayment and flashing, and what types? 

• How do you handle areas like chimneys, skylights, and valleys? 

• Can you explain the fastening system you use? 

• Do you follow manufacturer installation? 

• How long should this installation take? 

Maintenance 

Routine inspections and maintenance, primarily keeping the roof clean and free of debris, can contribute to the roof’s longevity and warranty compliance. A properly trained and experienced contractor should provide clear, detailed answers on what maintenance is required for long-term performance and protection. Make sure to determine this from your contractor by asking questions like: 

• What regular maintenance is required? 

• How often should inspections be performed? 

• Are there specific cleaning or repair techniques to avoid damage? 

• Will you provide a maintenance guide or tips after installation? 

Starting Your Project 

Installing a metal roof can be a significant investment, but it can also enhance your property’s value, boost curb appeal, and provide lasting peace of mind that your home is well protected. 

By having these conversations with contractors, you’ll gain a clear understanding of which metal roof can best maximize the longevity of your home. These factors will guide you to a successful project.
