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
Types of Steel Deck used in Green Building Construction
If you were in the construction industry and would like to build a large building structure, then you must have heard the word Metal Deck. And with major heavy documents on the internet, you must have been confused about what it is and how it can be used in construction to make it more cost-effective and to increase the life cycle of the building. Well, this blog will help you break down a few forms and types of steel deck material that will suit your needs. What is Steel Deck? Steel Deck is a cold formed sheet of corrugated steel supported by joists or beams of steel. It is used for supporting a roof’s concrete or insulating membrane. It was developed to provide the roof and floor systems with a structurally efficient product. The design and manufacturing optimize the steel ‘s properties to produce a high strength-to-weight ratio that decreases material handling and erection costs and retains durability. Bansal Metal decks have established over 10 years of satisfactory performance. Even after being a structural component and with its uniform quality these metal decks can provide an attractive appearance, especially when using the properly defined shop and field-applied coatings. Steel deck is also an integral component of several fire-rated assemblies licensed. There is a broad range of metal deck products available in the market today, but it is divided broadly into two categories: roof deck and composite floor deck. The metal deck is an element of the structural panel which acts as a floor or roof surface. The deck is roll-shaped from sheet steel of solid consistency and is designed to stretch over joist or purlins. Variations in a deck like thickness, shape, and depth can be used to fulfill a number of loading conditions and ranges. The supporting structure is fastened to allow it to act as a diaphragm and to provide the lateral bracing for the framework. Types of Steel Deck Sheets: Types of Metal Deck Assemblies: Four types of steel decking are commonly installed in the non-residential steel construction industry throughout the world. These are roof deck, deck form, composite deck, and deck specialty. #1 – Roof Deck: The steel roof deck is the primary part of the framework used in almost all flat roofs. The deck is a structural panel that extends over roof joist or purlins to provide a flat surface where the weatherproof roofing can be applied. For most roofing materials, such as built-up roofing, membrane roofs, or insulated sheet steel roof assemblies, steel deck is the point of convergence. The roof deck has also been used in more rare sloping or curvy structures. A steel roof deck is more than just a roof, a foundation upon which the roofing system depends. The design-engineering purpose is to support the necessary loads structurally as well as the designer-specified roofing membrane system while maintaining the building owner’s and appointed architect’s architectural goals the cost control interests can be calculated. #2 – Form Deck: Steel form deck is used as a framework for holding poured concrete. The structure is a permanent steel foundation for the slabs of the cured concrete floor and needs no cost of removal of the material. This types of steel deck is quick, easy and affordable to install, unlike composite deck. However, the form deck does not add to any strength of the concrete slab. Deck form steel structures are available in different depths. All are widely used as an affordable way in floor and roof construction to protect concrete slabs during building. This different form deck helps eliminate the need for expensive temporary shoring. However, the spacing of structural members directly affects related cost consideration – the deeper the decking higher the cost, the wider the spacing again higher the cost of the structural members. #3 – Composite Floor Deck: When the steel floor deck was first installed, it was mainly used as a fixed, or “stay-in-place” modified version of Traditional Roof Deck Profiles for a reinforced concrete poured into place slab. There were some benefits over conventional removable form-work in cost and shorter construction time for this kind of concrete form-work. However, there were some situations in which the deck had no concrete cover and was the sole load-carrying element. The term for these deck forms is floor deck or non-composite deck. The Deck was the positive moment support in the reinforced concrete slab by interlocking the steel sheet and the concrete slab. Additionally, the deck even acted as the concrete formwork. The resulting combined component was now recognized as a composite slab and the steel plate are known as a composite. The simple steel floor deck in place of the more powerful composite deck is no longer manufactured in any substantial quantity. #4 – Specialty Deck: Specialty decks include a broad variety of styles, levels, depths and combinations of decks. These styles of decks were designed to provide owners and architects with a larger pallet with more choices with decorative, architectural roofing and floor construction. It is the best way to give your building a modern look. But not all manufacturers of decks bear such profiles and others are specialists in this line of items. Contact the nearest metal deck manufacturer or supplier, as it is better to test whether they are holding the type you want. If you are looking for a metal deck also contact Bansal as they provide a wide variety of specialty decks and can customize according to your need.

Types of Metal Decking Material: #1 – Steel Deck: The steel decking can provide additional stability to a structural frame when used as flooring. To maximize strength and support the roofing materials, a narrower rib pattern must be created when used as roof decking. Steel decking is a cost-effective, durable and simple to install alternative for builders. It offers high quality as cold-rolled steel material, with little maintenance. Carbon decking that is exposed
