How to Install Metal Roofing
Metal roofing is an excellent choice if you're looking to replace your old roof. Metal roofs last longer than asphalt shingles. They also insulate better, which can help you save energy.
For metal roof installation, it's best to hire a professional if you aren't confident in DIY projects. These guidelines are intended to help you feel more confident about doing this task.
Pre-drilling
Pre-drilling is a crucial step in the installation of metal roofing. Pre-drilling ensures that screws penetrate the panels and are held in place.
If attaching panels onto solid wood substrate, it is important to predrill. This will decrease the likelihood of screws being driven in at an awkward angle which could lead to leaks later.
Metal roof installations may require fasteners with different head styles like flush, flat and countersunk.
These self-drilling screw fasteners do not require any predrilling, making them an excellent choice in areas where there are corrosive environmental elements.
Underlayment
It is essential to have underlayment in order for a metal roof to be installed. It provides insulation, protects the deck against damage, and ensures compliance with building codes.
Many advantages are offered by synthetic underlays to builders. They are long-lasting, fire-resistant, and many of these underlays can be recycled.
Their adaptability is another advantage. They can be installed even in cold weather conditions. This makes them contractor-friendly and increases safety.
Synthetic underlays don't wrinkle, and can withstand long exposure to the sun. This is especially important for installers, as it allows them install roofs without worrying that they will dry out or compromise their performance.
Felt paper is commonly used as an underlayment material on roofs. Also known as roofing paper or asphalt-saturated fel, it's often called roofing tarpaper. This product is made of natural fibers and cellulose, with a waterproofing agent such asphalt. The popularity of felt paper underlayment is due to its affordability, ease-of installation, and suitability for new construction projects.
Panels
The panels are the core of your metal roof. How you treat them can make a big difference in their durability. Long panels (30 feet or more) may need to be handled or lifted with special care. It's best to work together and use multiple lifting points underneath each panel to prevent damage during transport.
For metal roofing panels to last a long time, it is important to place them correctly and squarely. It will protect their modularity, and ensure their structural integrity.
After you have placed the first panel, place the next one so that it is overhanging by the amount recommended by your roofing contractor (usually about 1 inch). Secure each panel by fastening two 24-inch screws to their outside-facing sides.
Install ridge caps at the ends of your roof in order to protect it against rain damage and ice. These prevent water seepage into the gutters and onto ground. You might also need closure strips along the edge depending on your ventilation system.
Flashing
Metal roofing installations require flashing. It covers any areas where leaks are likely and directs water away.
You can make flashing from a variety of materials, including metals. It is often used to seal around roof projections and joints. However, flashing can also be used underneath shingles to provide extra strength and protection.
Flashing is often applied around the edges of roof components before they are attached. This serves to protect the edge from rain, snow, and strong winds that can lift shingles.
Aprons are another type. These look like an "U", and help collect water from roof slopes that meet walls. These flashings are usually manufactured by your Denver roof company.
Aprons are not the only flashings that are used around roof penetrations like chimneys or skylights. Valleys, joints, grooves, and projections should also be protected.
