How to Install Metal Roofing
Metal roofs are the best replacements or additions to your construction. Not only are they an attractive alternative to asphalt shingles but are also strong enough to withstand and survive hurricanes and wildfires. Metal roofs are extremely durable with a life span of 50 years or more depending on the type of metal used as well as the climatic conditions. There are several advantages of using metal roofs such as energy savings owing to their ability to reflect the sun’s heat, their tendency to last for decades, strength and durability and much more. Moreover, metal roofing sheets are cost-effective with respect to maintenance and can be easily configured into different profiles. The installation of metal roofing can be a tad bit complicated and can slightly vary based on the brand of panels you select. Bansal Roofing recommends that you seek the help of 1-2 individuals and fall protection equipment designed for roof work. It is important to understand the safety aspect of installing metal roofs. Always ensure prioritizing your own safety when working above the ground. Use gloves and safety goggles and use saws or power drill like materials with utmost safety as well. Ensure no electrical wires or low branches are hanging over the roof. Secure your ladder at the base and the point of contact with the roof. Don’t forget to test the ladder to be certain that it will not shift under your weight. Use proper fall protection equipment and be sure of the system. That it is anchored to your roof studs correctly. Wear appropriate safety shoes. Before getting to the steps of installing metal roofing, it is important to understand the various types of metal roofs that exist. Metal roofs are made from a variety of metals such as tin, zinc, steel, aluminium and copper. Every metal has its own advantages and disadvantages as well as cost consideration like factors. Steel, for instance, is the least expensive option while copper is the costliest. In addition to choices of material, metal roofs are also available in 3 design types; Through-fastened panels known as corrugated panels, Modular panels and Standing seam or crimped panels. While through-fastened corrugated metal panels are the most common of the 3, they are common and readily available roofing that can be installed over roof sheathing or purlins. Modular panels on the other hand are mimics of asphalt shingle and tile like roofing materials and are available in a wide range of colours and styles. Crimped or standing seam panels install over solid or skip sheathing; which is sheathing with gaps in between, and has a very complex installation process. Installing Metal Roofing Panels: #1 – Measure the Roof: Whether you install a metal roof with off-the-shelf corrugated panels or by replacing the special order, it is imperative to have the right length and amount of materials which can be started upon by knowing the square footage of the roof. In addition to knowing the square footage, you must also need to know the length of each section from the ridge to the outer edge of the eave. This distance will give you an idea of how long the panels need to be. For a basic gable roof, start by measuring the rake of the roof which is the point from the ridge to the outer edge of the eaves. For example 14 feet. Now measure the width of the roof: From one side of the roof all the way to the other side, including the eaves on each end. For example 35 feet. Multiply these two numbers to get the area of one side. For instance: 14 x 35 = 490. Multiply the result by 2 to get the total square footage of the roof. For example: 2 x 490 = 980 square feet. Order roofing supplies by the square foot, which shall also lower the chances of any excess or wastage. Try to order panels sufficiently long to run the full length from the ridge to the eave so that seams can be avoided. Be sure to order your roofing screws at the same time as your metal roofing panels so that you’ll match the colours, a service available at Bansal Roofing.

By removing the old roof you will be able to inspect the sheathing and flashing as well as mend any problem areas before moving forward. This reduces the chance of a leak. Begin from the top of the roof and remove the old shingles along with the vents and flashing underlayment. Hammer down or pull off any large nails that are exposed in the open by the removal. Inspect the underlying roof sheathing for damage. Make any needed repairs by using sealants and roofing adhesive. Install a layer of roofing underlayment, including a layer of felt paper or rosin slip sheet, as a personal recommendation from Bansal Roofing. Metal panels expand and contract at different rates than the sheathing, hence it’s important to follow the manufacturer’s guidelines regarding underlayment. #3 – Install Drip Edge and Closure Strips: A comprehensive guide to the same is; Use 1 1/4-inch galvanized roofing nails to install a drip edge along the eaves and rake the roof. Nail into the sheathing about every 16 inches. If installing multiple runs of drip edge, lap them by 1/4 to 1/2-inch and keep the nail back from the lapped joint. If there are gutters installed on the eaves, the drip-edge flashing should be installed to overhang the lip of the gutter by about 1/2-inch. Once the drip edge is installed around the perimeter of the roof, add sealant tape along the top of the drip edge and about 1 inch in from the edge of the drip flashing. With the sealant tape set along the drip edge, remove the top protective
5 Advantages of Metal Decking Sheets
Metal decking or steel decking has become one of the most preferred methods of construction in the recent years and there are various metal deck sheet suppliers that have emerged recently due to its newfound popularity in constructions of multi-storeyed buildings because of the flexibility that it provides combined with high strength. It also considerably speeds up the construction process. Due to such benefits, it has found usage in residential, commercial as well as industrial building constructions. Here are 5 advantages of metal decking that make it a desirable choice for construction. Advantages of Metal Decking: #1 – Less Weight: Slabs made with steel decking have high structural strength compared to traditional concrete slabs. This creates a high strength-to-weight ratio which allows for a massive weight reduction. This proves to be much more beneficial for multi-storeyed buildings as it brings down the entire weight of the construction significantly which can allow for lower foundation sizes. Metal decking makes the slabs lightweight and reduces the amount of work or support props required for slab casting. #2 – Cost Saving: Due to the reinforcement and strength given by the metal deck, in cases of composite slabs, the amount of concrete used in the slabs can be reduced by a large amount while maintaining the same strength. Moreover, the reinforcing steel can be reduced by 25% as the deck profile itself contributes largely to the tensile reinforcing property and thereby saves time and material required. This results in lower costs.

This greatly minimises work on-site and can help in faster construction. Moreover, the laying out of steel decking does not have to obstruct other processes being carried out on various parts of the construction site. In fact, the deck can be used as a working platform during construction and the masonry and other work can be carried out unhindered during and after the casting of the slab thereby reducing cost, time and labour. This allows for speedy and safe construction and requires less manpower to handle the activities. #4 – Easy Installation of Shuttering Material: Metal deck sheets act as composite members and as permanent shuttering resulting in savings of supply installation and installation of shuttering material. Additionally, provisions can be made on the steel decking or metal decking to fix cable trays and pipes which can then be easily laid out once the metal decking is in place. This significantly reduces costs incurred during the installation of these services on conventional slabs.

The strength of the concrete combined with flexible reinforcement of the metal decking serves to provide an all-round stronger slab that can withstand a great amount of load over a long period of time. No major reinforcement is required unless the design parameters demand. The slab thickness can be reduced which can allow for lighter slabs while maintaining the same strength. This makes way for reduced foundation loads resulting in lesser material consumption and thus lowering the cost. Those were some of the benefits of metal decking which have made it such a popular method of construction these days.
