Winterproofing Series: Roofs

Winterproofing Series: Roofs


There is a growing interest in preserving historical structures, understanding historical architecture, and using traditional building materials and techniques in a sustainable way. With colder snaps already sweeping across the UK, we will be taking a look at some ways in which you can winterproof your historic buildings with sustainability and preservation in mind.


This week we’ll be looking at roofs and how we should react to damage, along with looking at ways we can be proactive before damage is inflicted.


The materials used to roof historic buildings have varied over time and depending on the location of the building. Some of the most common materials include:

  • Slate: Slate is a natural stone that is durable, fire-resistant, and water-resistant. It is also relatively easy to work with, which made it a popular choice for roofing historic buildings.
  • Tile: Tile is another durable and fire-resistant roofing material. It is also available in a variety of colours and shapes, which makes it a versatile choice for roofing historic buildings.
  • Metal: Metal roofs are becoming increasingly popular for historic buildings. They are durable, fire-resistant, and water-resistant. They are also relatively lightweight, which can be important for older buildings that may not be able to support the weight of a heavier roof.


The style of a roof can also provide clues about the building's history and use. Some of the most common roof styles for historic buildings include:

  • Gambrel: Gambrel roofs are characterised by their two-sided slopes, which create more usable space in the attic. They were often used on barns and other farm buildings.
  • Gable: Gable roofs are the most common roof style for historic buildings. They are characterised by their two triangular slopes that meet at a peak in the centre of the roof.
  • Hip: Hip roofs are characterized by their four triangular slopes that meet at a point at the top of the roof. They were often used on larger, more formal buildings.


When thinking about repairing roofs, it is important to consult a qualified roofing contractor who has experience working with historic buildings. They should possess knowledge of traditional materials, techniques, and preservation guidelines. A good place to find contractors is the National Heritage Roofing Contractors Register which contains a list of qualified and experienced heritage roofing contractors at the level of Roof Master, Craft Roofer or Craft Roofer Operative.


Once a suitable contractor has been obtained, work with them to understand your building better.

  • Preservation: The primary goal should be to preserve the original materials, craftsmanship, and architectural integrity of the roof. This may involve using salvaged materials, replicating original techniques, and consulting with preservation specialists.
  • Compatible Materials: Choose roofing materials that match the original appearance and performance characteristics of the historic roof. Consider materials like slate, tile, or metal that are compatible with the building's style and period.
  • Reversible Repairs: Whenever possible, employ reversible repair techniques that allow for future maintenance and potential restoration. Avoid irreversible modifications that could compromise the historical character of the roof.
  • Documentation and Records: Thoroughly document the repair process, including the condition of the roof before and after repairs, the materials used, and the techniques employed. Maintain records for future reference and preservation purposes.
  • Compliance with Regulations: Adhere to local regulations and guidelines for historic building renovations. Listed building consent is likely to be required.
  • Long-Term Maintenance: Establish a regular maintenance plan to monitor the condition of the roof, address minor issues promptly, and extend its lifespan. This may involve regular inspections, cleaning, and preventive maintenance.


Remember, repairing a historic building's roof is a delicate task that requires careful consideration of preservation principles, compatible materials, and expert craftsmanship. By prioritising preservation, using compatible materials, employing reversible repairs, and engaging qualified contractors, homeowners can ensure that their historic roof is sensitively restored while preserving its historical integrity.
