  • Metal roofing sheets
  • Polycarbonate roofing sheets

Steel roofing solution has in recent times evolved as winner in roofing sheets market due to various factors ranging from Aesthetics, cost effectiveness, recyclability, low maintenance, durability and energy efficiency. Whether you are buying a home or planning of installation, here are some of the few reasons why steel is better than conventional roofing.

  • Light Weight and high strength – As compared to weight of other roofings like cement tiles, the metal roofing sheets are very light weight thus saving on the additional cost of engineering and supportive structure of the building. Metal roofing sheets can also be installed on the already existing structures/ roofs without or with minimum additional support.

  • Superior Aesthetics with design flexibility – The metal roofing sheet enhance the aesthetics of the structure and gives it a stylish look.

  • Fire/Termite resistance – Most of the metal roofing sheets are non-combustible thus proving a good resistance from fire. These are also resistant to termites unlike the conventional roofing sheets.

  • Variety of colours – Colour coated steel sheets come in a variety of aesthetically pleasing colour. One can choose from various options of colours based on their requirement and personal taste.

Roofing for Coastal Areas – Choosing the best roofing material for your projects in saline environments

Metal roofs are ideal when it comes to industrial roofing, due to many virtues it carries. They are tough enough to survive more with minimum maintenance. They are good reflectors of heat and protect from extremities of weather. Especially with colour coated roofing sheets, there are plenty of aesthetically pleasing options available.

While metal roofs will do exceptionally well in hot & wet areas, coastal regions pose a different challenge altogether. Several tests and years of experience have demonstrated the ill effects – such as corrosion – of exposing metal roofs to the salinity found in the air in coastal areas. While it is true that all metal roofs do not corrode at the same rate, the salty air and humidity react with the metal roof and eventually cause damage.

Roofing options for coastal regions;

Metal roofing sheets have evolved in the past few decades. Especially with the different types of coatings that prevent them from getting affected as compared to non-coated metal.

Today there are few options in metal roofing that are drafted for extreme saline or coastal topographies.

  1. Galvanised Roofing

    Galvanized steel is relatively inexpensive and can provide considerable corrosion resistance if installed properly. This roofing material is made of alloyed steel with a zinc coating, which will protect your roof from rust, strong winds, and rain. But the lifespan of galvanised roofs largely depends on the thickness of galvanisation. Higher the galvanisation thickness, greater is the lifespan but this also increases the cost of the roof.


  2. Aluminium Roofing

    Aluminium roofs have grown in popularity recently, due to their resistance to corrosion and their energy efficiency. Aluminium reflects light, emits heat, and can save you some money on heating and cooling costs for your building. While aluminium has greater corrosion resistance, it lacks the strength of steel and is very expensive as compared to other roofing options


  3. Zinc-Aluminium alloy coated steel Roofing

    Zinc-Aluminium alloy coated steel roofing combines the advantages of both galvanised roofing and aluminium roofing and provides optimum performance at lower costs.

    Zinc-Aluminium alloy coated steel is easily available and is widely used all over the world for residential, commercial, industrial and infrastructural applications.

    An advantage that Zinc-Aluminium alloy coated steel has over normal galvanized material is that it has enhanced protection abilities. Over time, Zinc-Aluminium alloy coated steel tends to perform better than galvanized steel, especially when exposed to water or other liquids that can speed up the oxidation process. Even after a few decades, Zinc-Aluminium alloy coated steel will be less likely to rust than normal galvanized steel.


Tata BlueScope Steel manufactures and supplies variant of Zinc-Aluminium alloy coated steel, specifically designed and tested for severe marine climates; COLORBOND® Ultra steel . This products from Tata BlueScope Steel offers you aesthetics and long-lasting performance; with excellent protection from erratic weather conditions.

Thinking about re-roofing, how about a transformation in your roof system

Thinking about re-roofing, how about a transformation in your roof system

Industrial roofing structures often deteriorate due to prevailing weather conditions, exposure to chemicals or pollutants and several other environmental factors. Time and climatic conditions cause a lot of wear and tear of commercial and industrial roofing structures and components. After considerable years of existence, roofing of any given industrial or commercial facility needs an overhaul or complete re-roofing in some cases.

Industrial roofing costs vary widely and may seem expensive regardless of the type or quality. But it is this roofing that is the only thing standing between your business and the harsh environmental conditions. Roofing failures can cause damage to expensive equipment and result in increased downtime. Unattended roof problems can cause financial loses or even spell an end for your profitable business.


So, how do you know that it is the right time to upgrade your Roof?

Here are some important signs that show that your roof needs repairs and replacement

  1. Age of the Roof
    Most experts agree that a typical GI or an asbestos roof will last between 8-12 years depending on the prevailing weather conditions. If it is older that 10-12 years, chances are the roof needs to be replaced
  2. Interior Water Incursion
    This is the most obvious sign of a roof damage. If left unattended, the problem aggravates and turns into serious water incursions. Reaching out to a professional for an assessment is the right thing to do in such a situation
  3. Deteriorated asbestos roofs
    There are many industrial clusters in India which were established in the 1990s. Many buildings were built by using asbestos roofs. These buildings now definitely need their old deteriorated roofs to be replaced
  4. Deterioration Of Roof Supports and sagging roofs
    If there are signs of such dips, low spots or sagging of roofs and areas on roof with water pooling, this may indicate that the underpinnings and supports of the roof have been damaged. In case of insulated roofs, the insulation is soaked wet and contracted and the joists and rafters holding up the roof are broken or sagged.
  5. Corrosion and blistering
    Humid climate, proximity to sea and pollution can cause corrosion in metal roofs. The corroded roofs are prone to leakages, higher maintenance and further result in damages to equipment under the roof.

Assessment and allocation of funds is only the initial step a facility manager or owner takes while planning for a Re-roofing project. Selection of the right roofing materials and hiring a capable roofing contractor is the most important factor to make sure the re-roofing project is completed successfully.


Selecting the Right Roofing service provider

In India, the process of re-roofing is indeed complex and facility owners or managers often face many challenges during the process. Fragmented suppliers, absence of one-stop-solution and lack of scalability as per project requirement; are some of the issues faced while taking the right decision.

While considering re-roofing services, it can be tempting to go for the lowest bid. The lowest bid holder may save your business capital in the short term but over time such a decision can have an adverse effect and result into higher losses. In an effort to offer a lower price, the contractor may use cheaper materials, unsafe work practices and untrained manpower or the contractor may be uninsured which can further lead the fate of project into uncertainty.

Below are some of factors to consider while selecting a roofing contractor

  1. Installation expertise and quality workmanship
  2. Cost effectiveness
  3. Quick turnaround time
  4. Usage of high quality roofing products
  5. Re roofing techniques that enable minimal downtime of your business operations
  6. Insurance, licences and certifications
  7. Recommendation and references

Factors to Be Considered While Designing A Roof System

Selecting & specifying the most appropriate roof system for a project requires solid past experience with several of the available materials and an understanding of roof assembly materials and system options. This article aims to provide design guidance for high-performance industrial roofing sheets. Shared below are the factors to be considered while designing an industrial roof system.

  1. Load Acting on The Roof: Roofs are constantly under pressure. A roof must be built to endure both upward and downward pressure acting on it. Here are a few weights that industrial roofing sheets are subjected to:
    • Dead Load: This includes the weight of the roof structure itself, self-weight of sheeting and purlins, rooftop solar, platforms and walkways along with all the permanently attached materials or structures. Metal roofing sheets in general, are stronger, yet lighter as compared to other roofing options.
    • Live Load: People walking or working on the roof contribute to a load of around 75kg/sqm (as per IS 875: Part 2)
    • Collateral Load: Any hanging load from purlins
    • Wind Uplift Load: Wind uplift load refers to the weight that hits the wall of a building and disperses upwards, creating an uplift force on the roof. This load is resisted by the roof’s downward pushing dead load.
  2. Effective Roof Slope
  3. Roof slope and Roof length play an important role in the selection of profile as well as in gutter design. An increase in the roof slope increases the discharge speed of the water, thereby affecting the gutter and downspout design measurements. A Shallow roof slope and a longer roof length with many numbers of end laps increase the vulnerability of water leakages as the wind will always carry water which will try to penetrate the end laps. In case of a longer roof with lesser crest depth, heavy rains will lead to greater accumulation of water towards eave gutter. This water will try to escape from side laps. If the site is located in a geography where there are high day and night temperature differences, the metal roof will undergo thermal expansion and contraction which will enlarge holes around the screw and lead to leakages. The best bet for shallow roof slope and longer roof will be concealed site roll formed single length panel.

  4. Choosing the Right Roof Profile and Its Thickness
  5. Roof profile sheets constitute a large part of a building surface and contribute to its aesthetics. It serves as a protection to the basic structure from dampness. Choosing the right roof profile includes considering both, the roof slope and the general view of the building. Low-slope roofs require wide-based profiles to allow the rainwater to discharge. Steeper slopes enable to use more patterned profiles. Thickness of the roof profile  plays an important role based on the purlin spacing.

  6. Effective Purlin Spacing
  7. Purlins are secondary members mounted on Columns and Rafters. Usually, Roof Purlins support the Roof Sheets, Insulation, Vapour barrier etc.  Design of purlins depends upon the Loads on the roof, hanging (collateral) loads under the purlin and Span of the purlin. Some commonly used purlin shapes are ZEE, ZED and CEE purlins which are required for Steel Buildings. Purlin spacing varies basis the roof slopes.

  8. Optimized Purlin Section
  9. Based on wind pressure, every building structure has 2 zones: end zones & intermediate zones. For both the zones, purlin shape and thickness are designed to match the loads. Tata BlueScope Steel has 3 kinds of Purlins:

    1. CEE Purlins
    2. ZED Purlins
    3. ZEE Purlins

    The purlin spacing is adjusted based on the calculation of complete wind load in any building.

  10. Coating Mass and Paint System of Roof Materials
  11. Roof coatings are designed for adding a protective layer to the roof. It increases the service life of roof assemblies LYSAGHT® range of premium pre painted roofing sheets and wall cladding sheets are manufactured from high-strength steel; COLORBOND® steel and ZINCALUME® steel for longer lifespan. Zn-Al alloy coated steel ensures excellent corrosion resistance that enables longer life under extreme weather conditions, specifically for Industrial buildings, Pre Engineered buildings, infrastructure applications, Light Gauge Steel framing systems and commercial applications Wall cladding and roofing products made from COLORBOND® steel roof sheets are termite and fire-resistant.
