The roof of a building is one of the most important components of its architecture, serving many purposes, from protecting the interior from external elements to defining the aesthetic and structural integrity of a structure. Installing a metal roof is a smart investment for any property owner. Known for their durability, efficiency, and aesthetic appeal, metal roofs can provide decades of reliable service.
Achieving a successful installation requires careful planning and execution. Metal roofing installations can vary greatly depending on the type of existing roof, whether you’re working with exposed or hidden fasteners, and the desired style of the new roof. Here are some essential pro tips to ensure your metal roof installation project goes smoothly and delivers excellent results.
Tip #1 – Choose the Right Materials
The first step to a successful metal roof installation is selecting the right materials. Consider your budget, the climate of your area, and the desired aesthetic when choosing your materials. There are several types of metal roofing, each material has its own benefits and drawbacks:
- Aluminum: Lightweight and resistant to corrosion, making it ideal for coastal areas.
- Steel: Strong and durable, often coated to prevent rust.
- Copper: Highly durable and develops a patina over time, which can be visually appealing.
- Zinc: Long-lasting and low maintenance, but more expensive.
Tip #2 – Proper Measurements and Planning
Always Start Square. When installing a metal roofing panel, it is important to start square — meaning your vertical lines are all squarely aligned with the eave. This is a crucial step because if the first panel is even slightly tilted, the rest of the panels will all be tilted as well.
Accurate measurements are crucial for a successful installation. Begin by measuring the dimensions of your roof, including the length, width, and slope. Calculate the total square footage and add an extra 10% to account for waste and overlaps. Create a detailed plan that includes the layout of the metal panels, the placement of screws, and the location of flashing and trim. This will help you visualize the project and ensure you have all the necessary materials.

Tip #3 – Install a Moisture Barrier
Installing a moisture barrier is essential to protect your home from leaks and moisture damage. Use a high-quality underlayment, such as synthetic underlayment or roofing felt, to cover the entire roof deck. This layer acts as an additional line of defense against water infiltration.
Tip #4 – Use the Right Fasteners
Using the correct fasteners is critical for the longevity of your metal roof. Opt for corrosion-resistant screws with rubber washers. These screws should be long enough to penetrate the metal panels and secure into the roof deck without causing damage. Place the screws in the flat areas of the panels to prevent water from pooling around the fasteners. Always screw fasteners straight in, paying careful attention to not overtighten them. Test your drill tension on a piece of scrap metal or an area that can be easily covered by a ridge cap or other flashing.
Tip #5 — Safety First
Safety should be the top priority during any roofing project. Use proper safety equipment, such as harnesses, safety glasses, and non-slip footwear. Be mindful of weather conditions, and avoid working on the roof during rain or high winds. Wearing protective rubber-coated gloves when installing metal roofs will not only protect you from sharp edges but will also give you a good grip on the materials.
Tip #6 — Inspect and Maintain
Once your metal roof is installed, perform regular inspections and maintenance to keep it in top condition. Check for loose or missing fasteners, inspect the flashing for signs of wear, and clean any debris from the roof surface. While it may seem trivial, these tiny pieces of metal can result in unsightly rust spots where they rest on the roof. Address any issues promptly to prevent more significant problems down the line.
Tip #7 – Attend Metal Roof Installation Training at METALCON
The Metal Roof Installation Training, certified by the Metal Construction Association (MCA), is one of METALCON’s signature and most popular workshops. Hundreds of metal construction professionals have been certified through this program at METALCON since its inception. This two-day, eight-hour introductory certificate program is based on MCA’s Metal Roof Installation Manual.
During the course, participants experience quality time with industry experts, receiving classroom training in topics including substrates, safety, sealants, flashings, panel types and connections, tools, fasteners, maintenance, and more. Following the classroom training, participants then access the Exhibit Hall to experience first-hand what they have just learned, further educate themselves on the metal systems, and network with industry experts. For those new to metal roofing, this program is especially useful to learn about the industry and experience practical training. Upon successful completion of the training program, individuals receive MCA’s Metal Roofing Certificate of Completion.
