Metal Roof Installation: DIY vs. Professional Help

professional metal roof installation: necessary equipment

Professional metal roof installation or DIY metal roof? Let’s compare and decide. While the roof is a fundamental necessity, it is not just the house cover, it has a crucial role in the integrity, thermal performance and the visual appearance of the home. For this reason, a roof is a very significant item in the estimated price of a house and it is clearly one of the most strategic interventions to increase the residential property’s market value.

This is particularly true in Toronto and in the Greater Toronto Area (GTA), where the climate ranges from harsh winter cold to scorching summers. Among the different types of roofs, metal roofing prevails as the ideal roof for today’s homeowner. This type of roofing presents unique and enviable qualities of durability and noteworthy good looks.

The main advantages which have been taken into consideration in the growing popularity of metal roofs in metropolitan areas, such as Toronto, Mississauga and Brampton, and in picturesque destinations, such as London, Northern Ontario and Niagara Falls are longevity and resistance. The reflective properties of metal reduce heat absorption contributing to the household energy efficiency, significantly saving on air conditioning costs during the hot summer season.

The choice is how to install the metal roofing – either doing it by yourself or hiring a professional. The method of installment has not only the short term implication of the cost of installation but also has long term implication on the performance of the roof and its maintenance requirement. Understanding of the details of installment of metal roof and a thorough deliberation on the pros and cons of DIY and professionally engaged strategies will broaden homeowner’s awareness of the range of options in home improvement.

Overview of Metal Roofing Types

Sheets or panels made from G90 galvanized steel make metal roofing the most durable option. G90 galvanised steel is the most preferred metal for the manufacture of roofing materials because it is corrosion-resistant and very strong. This is why it is a popular option when it comes to the weather-changing climates of the GTA.

Types of Metal Roofing:

The variety of metal roofing types caters to different aesthetic tastes and architectural requirements. 

  • Metal tiles offer the appearance of traditional ceramic tiles but are lighter and more durable. 
  • Ribbed AG panels, known for their distinctive patterns of raised ribs, provide a sleek, contemporary look and are quick to install. 
  • Standing seam metal roofs are characterized by their raised interlocking seams, which conceal the fasteners, creating a smooth, modern finish that’s both waterproof and visually appealing. 
  • Lastly, metal shingles mimic the look of traditional shingle roofs but with the added benefits of metal, including lower maintenance and better fire resistance.

Key Benefits of Professional Metal Roof Installation:

  1. Longevity: They can last 75 years, five times longer than asphalt shingles.
  2. Weather Resistant: As a destruction-proof, heavy duty roofing system that can stand up against high speed wind gusts up to 240 km/h, the metal roof was precisely designed for constant exposure to harsh weather in coastal and rural areas of Ontario. In houses, buildings and houses that are located in areas with severe weather, the metal roof provides strong protection from storms and heavy wind.
  3. Eco-friendliness: Often made from recycled content and fully recyclable at their lifecycle’s end.

Physical Features

  1. Material Nature: Metal surfaces are engineered to be more resistant to grooves, cuts, scratches and dent, in comparison with other finishing options such as wood or paint.
  2. Energy Efficiency: The reflective nature of metal triggers a reduction in heat absorption, which in turn translates into lower costs for cooling and in return a more eco-friendly carbon footprint.

As these physical features suggest, metal roofing is a great combination of versatility in design with prolonged durability, resistance and eco-friendliness.This makes metal roofing a wise decision for Toronto and the area’s residents who have to contend with alternating weather and urban style every day.

DIY Metal Roof Installation

Installing a DIY metal roof is a great project for the active homeowner who likes to undertake hands-on tasks. Not only is it fun, but it will save a lot of money. When it comes to installing a new roof though, you cannot cut corners. It must be done right.

What DIY Installation Entails:

According to a detailed DIY instruction manual on Forbes, here are some steps you can take to install your very own metal roof:

  • Measuring: Accurately measuring your roof to ensure you purchase the correct amount of materials.
  • Preparation: Removing old roofing materials and preparing the surface for new installation.
  • Cutting and Forming: Cut the metal panels to the correct length; form the metal at any edges and corners if needed. A
  • Material: Also, you will need to shop around for a metal roof supplier willing to write invoices for the metal roofing sheets to people doing their own work, and not just companies.
  •  Securing the panels to the roof: ‘Bollocksing the thing together, making sure it’s plumb, all the panels go together right and the roof’s all tight with a seal so nothing leaks in’.
  •  Putting the final touches: Fitting trim and ensuring every nook and cranny is sealed tight.

Skills and Knowledge Required to do Metal Roof DIY:

Successfully installing a metal roof requires a range of skills and knowledge, including:

  • Basic Carpentry: Understanding how to measure, cut, and attach materials securely.
  • Safety Precautions: Using ladders, safety harnesses, and power tools safely to prevent injuries.
  • Building Codes: Local building regulations need to be understood, e.g., water heater installations have to be at least a specified height in order to meet local building codes.

Pros and Cons of the Metal Roof:

In general, I believe a DIY metal roof will have both benefits and drawbacks. On the one hand, it might be more beneficial than an ordinary roof in some ways and on the other hand, it could have some disadvantages as well.

Let us first discuss the PROS of installing a metal roof in general.

  1. Firstly, a metal roof will be much more durable and keep your home safe compared to a tiled roof and other simple type of roofs.
  2. Secondly, it will also keep your house warmer in cold weather, so you will not have a small temperature inside your home. I believe that these aspects are the most significant advantages.

Moving on to the CONS of a metal roof, these might be the drawbacks.

  1. Firstly, I believe that it will be more difficult to install than a normal roof. You will need at least three people to install it.
  2. Secondly, you might need to address some issues before you install this roof. For instance, you have to be sure that your roof is properly waterproofed.

To conclude, I believe that installing your own metal roof will be both beneficial and disadvantageous depending upon the reasons for choosing this type of roof.

Pros and Cons of DIY Metal Roof Installation:


  • Great Savings: The most compelling reason that anyone should embrace a DIY installation is because an installation professional’s services can cost you a great amount of money. 
  • Personal satisfaction: When you do an entire job from beginning to end, you have a strong feeling of accomplishment and being able to do a job your way. 


  • Risk of improper metal roof installation: Installation done without proper training nearly guarantees a mistake, which can range from a leak, structural damage to repair sooner than expected. 
  • It takes time: DIY can be time-consuming and difficult to fit around other responsibilities.  
  • Safety hazards: It is dangerous to work on a roof in itself but it is more risky when you don’t know how to use some tools and equipment that you have.

Taking these into consideration, it would be more appropriate for DIY metal roof to be installed by someone who has the right level of experience, has the right degree of skill, and understands the risk involved in paying less than half the proportionate cost of hiring a professional. It is important to ask yourself how much time you would want to spend on this project, having taken into consideration the amount of time that professionals take to complete it, and to also consider the risks of the mistakes that you might make (particularly if you do not have the right degree of skill or experience). A lot of people would find that the balance tips on the side of hiring professionals.

Professional Metal Roof Installation

However, there are many reasons to consider professional metal roof installation. It saves the homeowner time, ensures higher-quality workmanship and even peace of mind with the guarantee that 50-year transferable warranty coverage is provided with a professional roofers. This research has provided detailed information about how professional installation is done, the benefits of such installation and the drawback associated with it.

Process of Professional Installation of the Metal Roof:

  1. Initial Consultation and Estimate: Professionals will inspect your existing roof to determine its current condition, paying special attention to any underlying structural issues that might affect the performance of the new roof.
  2. Exact measurements: Measured to the proper dimensions of your roof for precision.
  3. Materials Preparation: Depending on the variant – be it metal tiles, shingles, AG panels, or standing seam – materials will be prepared and customized either off-site or on-site.
  4. Removal of the Old Roof or Preparation for Over-Shingle Installation: In some cases, the roof has to be taken off. But since metal roofing can be installed over shingles, if the structure can support the extra load (which it usually can), significant time and waste is saved while making the installation more green.
  5. Roof Deck Preparation: The roof deck is inspected and prepared, including blowing insulation on to the deck or adhering roof deck vapour barrier. Installation over existing shingles will also include a special purpose adhesive material. If being installed over an existing roof, the shingles are checked for flatness and then spiked into their sheathing to provide a stable working surface.
  6. Professional Metal Roofing Installation: Metal panels or shingles are installed, one at a time, with great attention to their sealing and alignment to each other in order to make them weatherproof, stable and durable. 
  7. Finishing and Clean-up: Edges, ridges, and gutters have been finished; whole area clean, property improved, roof restored.

Benefits of Hiring Professionals for a Metal Roof Installation:

Experience is needed for their expertise. Not all houses have the same pitch angle or the same number of windows. Anyone can attempt to fix other people’s roofs, but only roofers can do it effectively. They are the experts who identify problems immediately and are quick to do it. No amateurish work is done at the peak but only the professional way.

  1.  Warranty: Professional installation of the metal roofs comes with warranties on both the materials and labour, ensuring a relatively long-term protection against product defects and faulty installation. 
  2.  Compliance to Building Codes: The work conforms to the local building codes; this is important because it ensures safety and legality.
  3.  Stress Relief: Having people who know what they are doing install your shingles for you keeps the worry out of making a costly mistake on a major project.

Potential Downsides For Professional Metal Roof Installation

  • HIGHER COSTS: Professional jobs, including house repairs and remodelling, cost more than DIY jobs. However, running from a warehouse with a poorly measured piece of sheet metal, traveling around the world looking for exotic blue gutters, buying a huge amount of roofing accessories just for one small job, renting equipment – all of this can cost even more than hiring a professional.
  • Availability: Getting on a professional’s schedule may require some wait time, especially in the roofing season, which could very well push your project back.
  • Less personal control: Because professionals handle the bulk of the decisionmaking and the work, for some homeowners that means less control over the nitty gritty details of the installation.

Cost Comparison: DIY vs. Professional Installation

Initial Cost Comparison:

Cost savings: DIY metal roofing’s biggest appeal for many is the potential for substantial savings. A huge portion of a roofing job’s cost comes from hiring labourers. By opting to do it yourself, you rid yourself of this expense. However, achieving these savings requires you to pay retail for your materials and perhaps rent specialized tools.

Professional metal roof installation: Obviously, hiring a professional involves a lot more up front. You are paying at least for labour, and most roofing companies benefit from being able to buy materials wholesale so that alone makes things potentially much less expensive. However, overall, although you might get away with spending less on materials, the total will equal more than a DIY job would.

Long-term Cost Implications:


  • DIY metal roofing: While set up costs are cheaper, DIY installations might not always meet high standards of professionalism, which in turn could lead to higher maintenance, and perhaps the need for repairs as a consequence of the lack of professional perfection such as leaks or loose panels.
  • Professionally installed metal roof: get home with a metal roof and it may not have many problems, other than maybe the odd dent, because it has been well installed and has quality materials. This could result in less maintenance cost over the lifetime of the roof. 

Durability and Lifespan:

  • DIY metal roof installation: If you DIY your metal roof, you might not do it correctly, and you might have to replace it earlier or do maintenance on it sooner than expected.
  • Professional metal roof installation of a metal roof means that you will get a return on your investment in 10 years or less because of the extended lifespan – 75 years or more – and the lack of repairs you’ll be giving over the years.

Warranty and Insurance:

  • DIY metal roof installation: A DIY job has no labour warranty at all, and incorrect installation could void material warranties or even affect home insurance coverage of claims related to damage linked to the roof. 
  • Professional metal roof installation: Installations from contractors include a labour and materials warranty, and proper building codes and installation might help lower home insurance premiums and claims.

Repair Needs:

  • DIY metal roofing: The odds of a repair being needed in a DIY project due to installation errors or carelessness are higher than in a professionally installed project. This can lead to a costly repair, specifically one that may require a professional to undo poor foundational mistakes. 
  • Professional metal roofing installation: Although the professional installation costs more in relationship to the immediate installation of the house, in general, the roof is installed correctly the first time around and the need for repairs and the extent of such repairs would be reduced.

It is possible to argue that immediate savings are wiped out in a few years time when more money has to be spent on repairs and maintenance and on replacing the roof at a much shorter life. Secondly, while professional installation involves a higher outlay in the short term, it is more likely to guarantee better quality and reduce the likelihood of surprises in the long term. This alleadge also means that professional installation is inevitably a good investment for home owners who are considering longevity and quality. However, it is not that attractive for those looking for savings in the short term.

Making the Decision

Your decision of how to install a metal roof – whether it’s DIY or hiring a professional – will be based on personal and project-based criteria. This is how to make that decision.

Evaluating Personal Skill Level and Experience.

Think About Your Skills Regarding Metal Roof Installation Process:

  1. Have you undertaken this type of project before? 
  2. Have you installed a roof previously? 
  3. Metal roofing installation is similar to other structural work you’ve done in the home.

If you are untested, consider the time and skill it will take to learn these skills. Errors can be costly and can compromise the integrity of the roof.

Analyzing Metal Roof Installation Complexity:

  • Simple vs Complex Roof Designs: simple roof designs can be done as a DIY job, but those with a lot of slopes, valleys or that incorporate more architectural elements usually present problems that are best handled with professional supervision.
  • Think Through the Home’s Structure: Consider whether your home’s structural integrity (beams, joists, etc) is strong enough to handle a metal roof, especially if you intend to put it over existing shingles.

Budget Considerations:

Upfront Costs vs Long-Term Costs: You might be tempted by DIY system installation, like myself, because it saves you money upfront, but don’t forget that over time you’ll have to pay for maintenance and repairs. The more durable and well constructed a system is, the less you’ll have to spend on maintenance. Does professional installation provide value because it’s cost-effective, or because it’ll last longer and be less hassle to use compared with DIY alternatives?

Selecting the Right Materials:

  • Materials: Metal roofing comes in many different options of coating and colour, which differs based on the climate in Toronto and the GTA, as well as the home’s architecture.
  • Quality over cost: Invest in high-quality materials (even if expensive) that provide more longevity and better performance.

Finding Reputable Professionals For Metal Roof Installation:

  • Ask for licensing and certifications. Make sure your roofer is licensed and insured. 
  • Get estimates from different companies, and be wary of fly-by-night companies. Compare prices and service offerings.
  • Check reviews online to make sure the roofing company has a good reputation. 
  • Never sign construction contract of any kind without first leaving it with your attorney to review. 
  • Look At Past Projects:  Where practical, check out past jobs done by the contractor to see the quality of their work.
