Metal roofing is durable, energy-efficient, and low maintenance. Metal roofs can last a long time, depending on the climate and the type of metal used. They can also reflect the sun's heat and reduce cooling costs in some areas. However, installing a metal roof is not easy. It requires careful planning, proper tools, and safety precautions.
Choosing the Right Type
Metal roofing options include corrugated, modular, and standing seam panels. Each type has its advantages and disadvantages, as well as installation methods. For example, corrugated panels are the most affordable and easiest to install. Still, they have exposed fasteners that may leak over time. Modular panels are more expensive and require more skill to install.
Also, they have hidden fasteners and a more uniform appearance. Standing seam panels are the most expensive and complex to install. Also, they have no exposed fasteners and offer the best performance and longevity.
Before choosing a type of metal roofing, you should consider your budget, roof design, preferences, and local building codes. You should also consult with a metal roof installation contractor.
Installing the Underlayment and the Trim
Before the contractor installs the metal panels, they install an underlayment over the roof deck. The underlayment is a layer of material that protects the roof from moisture, wind, and fire. The most common type of underlayment for metal roofing is a self-adhesive ice-and-water membrane that seals around nails and screws.
After installing the underlayment, roofers must install the trim along the roof's eaves, gables, ridges, and valleys. The trim is made of metal strips that cover the roof's perimeter and create a finished look.
Installing the Metal Panels
The contractor will install the metal panels over the underlayment and the trim. It generally involves aligning, overlapping, and fastening them together.
They need to place corrugated panels on the roof so that they overhang the edge. They must align them perpendicular to the edge and fasten them to the sheathing with neoprene washer head screws.
Placing the Modular Panels
The contractor needs to place modular panels on the roof to interlock with each other along their edges. They must align them parallel to the edge and fasten them to the sheathing with hidden clips or screws. They must also space the clips or screws according to the manufacturer's specifications.
For standing seam panels, the contractor needs to place them on the roof so that they snap together along their edges. They must align them parallel to the edge and fasten them to the sheathing with concealed brackets or screws. Once you have installed all the metal panels, you can enjoy your new metal roof for years.
