Tips on How Metal Roofing is Installed

Introduction to Metal Roofing

How are metal roofs installed? This process can be tricky if you've never installed a metal roof before, which is why we offer some tips to help streamline the procedures for this challenging home improvement project. A metal roof can enhance the structural integrity of your home while increasing its value since it's one of the longest-lasting roofing materials available. And with proper installation, it's also the easiest to maintain. Read on to learn more.

Understanding the Advantages of Metal Roofing

Before making a final decision to install a metal roof on your home, it's essential to understand the benefits of metal roofing. The primary reason why metal is such a popular choice is its exceptional longevity. On average, a metal roof can last 25 to 50 years if it’s installed properly and well maintained. Furthermore, higher-end types constructed from materials like copper or zinc can endure for almost 100 years.

Another advantage is how lightweight the material is compared to other roofing options. In fact, if you wonder how metal roof panels are installed when they look so heavy, you might be surprised to find out that the panels are easier for a construction crew to lift and move around. This characteristic, in turn, translates into cost savings on engineering expenses and also saves time, as the installation process is simpler compared to that of shingles and tiles. Furthermore, you'll experience cost savings on your heating and cooling expenses because metal roofs effectively regulate temperature with their reflective qualities. Additionally, metal roofing is fire-resistant, potentially leading to savings on your homeowners' insurance policy.

How Metal Roofing is Installed

Installing a metal roof involves accurately measuring the roof’s dimensions to determine the amount of material needed and ensuring safety equipment like scaffolds and personal fall arrest systems are in place. The process begins with securing a moisture barrier to the roof deck, followed by attaching drip edges and closure strips. Metal panels are positioned starting at the eaves, overlapping each panel to create a watertight seal, with sealant applied beneath the overlaps to prevent leaks. Panels are measured and cut to fit around any roof penetrations, such as vents, chimneys, or skylights. The installation is completed with ridge caps along the roof's peak for added protection and a polished finish, ensuring a durable, secure, and aesthetically pleasing metal roof.

Setting the Roof Structure and Measurements

When it comes to installing metal roofing, one of the most important steps is to measure your roof’s length, width, and rise for one section. To get the rise, you’ll measure the distance between the lowest point of your roof and the highest point. From there, you’ll use the measurement of the rise to get the slope which is calculated by dividing the rise by the run (the distance across the roof). Next, you’ll compute the slope factor by squaring the rise number and adding it to the run’s measurement. After that, you’ll take the square root of that sum and divide it by the run. Finally, you’ll multiply the slope factor number by the area measurement which will give you the square footage for that section and consequently, the amount of material you’ll need to cover it. You’ll need to repeat this process for each section.

Though the process is extensive, getting accurate measurements will save you a ton of money in metal roof installation costs and ensure a successful process.

Safety Precautions and Equipment for Installation

In addition to taking accurate measurements, the roof installation crew must also exercise caution as they work near the edge of the roofing deck while securing the panels. This means that they’ll need scaffolds where they can safely stand while working. Of course, ladders provide access to the top of the platforms or aerial lifts, and in some cases, the roofers will need to use a Personal Fall Arrest System. If they are handling sealants, then they will be required to wear personal protective equipment to prevent exposure to the chemicals.

Addressing Roof Penetrations and Chimneys

Preparation is Key: Before you start installing the panels, it's crucial to ensure a solid foundation. Begin by securing a moisture barrier or roofing paper onto the roof deck. Pay close attention to areas around vents and,  if applicable, the chimney. Additionally, make sure to install drip edges and closure strips before proceeding to the panel installation. Once in place, add sealant tape along the drip edges and then position the closure strips on top, removing the backing paper to secure them

Panel Installation: As you embark on securing the panels, it's best to start at the eaves. Always remember to overlap the larger edges with the smaller edges of each subsequent panel. To ensure a waterproof seal, apply silicone sealant beneath each small edge. During this process, you may need to cut panels to fit around openings, such as vents, chimneys, or skylights. Ideally, you should have measured and marked the panels around these openings at the beginning of the roof installation process. To cut the panels to fit, you can use a circular saw or tin snips.

The Finishing Touch: Finally, when it's time for the finishing touch, don't forget about the ridge caps. To position them correctly, mark their location using a chalk line. Also, be sure to select the appropriate closure strip, whether it's vented or solid.

Final Inspection and Quality Checks

When inspecting the final result, you can start by standing a few yards away from the house and looking for any irregularities, including debris, stains, scratches, or dents. After that, you’ll gradually inspect the roof more closely, first using binoculars and then climbing up to it on a ladder for a walk-through.

Regular inspections should also be conducted twice a year to ensure that no major repairs are needed. Likewise, if you keep the roof free of debris and dirt, including the gutters, it will last for many decades.
