How to Install Metal Roofing?
Metal roofing can be a good option when replacing an old roof. Metal roofing lasts longer than asphalt roof shingles and is also more energy efficient by better insulate homes.
You should hire a professional to install your metal roof if you are not comfortable with DIY projects. You can do it yourself if you feel confident.
Pre-drilling
It is important to drill the holes before installing metal roofing. This allows the screws to penetrate the panels effectively and secures them in place.
Predrilling is also necessary when attaching panels or boards to solid wood substrate. Predrilling helps reduce the risk of screws being driven at an angle that could cause leaks.
Metal roofs require fasteners in a variety head styles.
Self-drilling Screw Fasteners are also ideal for locations with corrosive environment elements.
Underlayment
The essential step in the roof installation process is underlayment. It provides additional insulation and shields the deck to prevent damage.
Many benefits are available to building owners when using synthetic underlayments. They are fire resistant and durable, and many underlays can also be recycled.
Another benefit is their adaptability. They can be used even in cold temperatures, making them contractor-friendly.
Synthetic underlays are wrinkle-resistant and can withstand sun exposure for long periods of time. This is an advantage for installers since they can install roofs without worrying about it drying out or compromising its performance.
Feltpaper is often used for roofing, and it is also called asphalt-saturated felt. This product is composed primarily of natural fibers orcellulose combined with a waterproofing agents such as asphalt. Felt paper has been a favorite because of its affordability and easy installation. It is ideal for new construction projects.
Panels
Your metal roof's panels are the most important element. The way you handle them can impact their longevity. For panels that are longer than 30 feet, special handling or lifting may be required. In order to avoid any damage during transport, it's a good idea to have multiple lifting points below each panel.
Properly installing metal roofing panels is critical to their longevity. By doing so, you can ensure their modularity. This also helps to maintain their structural integrity.
Once the first panel is installed, position the next one above it so it hangs over it by the recommended amount (usually around 12 inch). Each panel should be fastened with two 24-inch screws at their outer edges.
Install ridge caps to protect your roof from rain damage and freezing. These prevent water leaking from gutters to the ground. For additional security, depending upon your ventilation system you might need closure strips along a ridge.
Flashing
Metal roofing installations do not include flashing. It covers the exposed edges of metal roofing and redirects water away from exterior walls and roofs.
Flashing can be made from many different materials, including metallics. It is most commonly used to seal around joints, roof projections, and may also be placed beneath shingles for additional strength and protection.
A flashing strip is typically applied around the edge of any roof components. It protects the edge from rain, snow, or strong winds that could damage the shingles.
Aprons, which are shaped like an "U", also help to collect water where roof slopes meet walls. This type of flashing is typically made onsite by your Denver roofing contractor.
Aprons are not all that are needed to protect roof penetrations such skylights or chimneys.
