Roofing for steel buildings: What to consider

When it comes to choosing roofing for steel buildings, selecting the right material is crucial if you wish to ensure longevity, durability, and overall structural integrity. 

Here at Hamilton Steel, we believe that structural steel stands out as the perfect material for the framework and cladding of agricultural, commercial or industrial buildings, ensuring the longevity of any structure. In this guide, we will explore various roofing options for steel buildings.

Factors to consider 

When it comes to choosing roofing for a steel building, there are a number of factors that you will need to consider when making your choice.

  • Weather-resistance: Your steel building will most likely face exposure to diverse weather conditions, from heavy rain and snow to intense sunlight. The roofing material and design therefore needs to be able to withstand these elements without deteriorating over time.
  • Weight: Steel structures are designed to be lightweight yet incredibly strong. However, weight should still be a key consideration when you are choosing your roofing, and it is advisable to opt for a material that won’t compromise the overall structural integrity of your building.
  • Durability: One of the major advantages of steel buildings is their inherent strength and durability. As such, the roofing that you choose should complement these qualities in order to maximise the overall strength of the building
    Cost-effectiveness: How cost-effective your chosen material is doesn’t just depend on the upfront purchase and installation costs, but how cost-effective the roofing is over time. This will, in part, depend on aforementioned factors such as weather-resistance and durability, and how often your roof requires repairs as a result of its performance in these areas.

Choosing your material

  • Metal roofing sheets: Metal roofing sheets are a top contender for steel buildings due to their exceptional durability, versatility, fire-resistance, and low maintenance requirements. Available in materials such as galvanised steel, aluminium, and zinc, these sheets offer superior weather resistance, preventing issues like rust and corrosion. They are also very lightweight, making installation easier and putting less stress on the steel structure of the building.
  • Built-up roofing (BUR): Built-up roofing, commonly known as BUR, consists of multiple layers of roofing felt or fabric alternated with layers of bitumen (asphalt) and finished with a top layer of a material such as gravel. While BUR can be durable and offer good waterproofing, it tends to be quite heavy, potentially exerting a considerable load on the building’s steel structure.
  • Concrete roof tiles: Concrete roof tiles offer a durable and fire-resistant option. However, their weight can be a concern for steel buildings, potentially requiring additional structural support. Concrete tiles may also crack over time due to their rigid nature, leading to maintenance issues and costly repairs.
