When to Replace the Roof of a Historic Building

Historic buildings are tangible links to our past, each brick and beam whispering tales of bygone eras. Maintaining these structures is about safeguarding cultural heritage for future generations. An important aspect of this maintenance is the roof, a building's first line of defense against the elements. However, time and weather inevitably take their toll, necessitating roof replacement. Here are the key reasons you might need to replace the roof during a historic building restoration.

Preserving Authentic Architecture: A Commitment to Heritage

At the heart of any historic building restoration project lies a commitment to preserving authentic architecture. Replacing a roof is not merely a functional necessity; it's an opportunity to honor the building's history and craftsmanship. Careful consideration must be given to selecting materials and techniques that are compatible with the building's original design and construction. This might involve consulting with preservation experts, researching historical records, and employing skilled artisans who specialize in traditional roofing methods. 

Enhancing Energy Efficiency: Balancing History and Sustainability

Historic buildings are often perceived as energy inefficient, with drafty windows and poorly insulated roofs. However, modern roofing solutions can significantly improve energy performance without compromising historical integrity. Incorporating insulation during a roof replacement can reduce heating and cooling costs, making the building more comfortable and sustainable. This aligns with contemporary environmental concerns and can contribute to the long-term viability of historic properties by reducing operating expenses. Choosing materials and techniques that balance historical accuracy with energy efficiency is crucial for responsible restoration.

Preventing Water Damage: A Shield Against Decay

The most immediate and pressing concern for any building, especially a historic one, is water damage. Leaky roofs can lead to a cascade of problems, from rotting structural timbers and plaster damage to mold growth and compromised foundations. In historic structures, where original materials are often irreplaceable, even minor leaks can have devastating consequences. Replacing a deteriorated roof ensures that the building remains watertight, protecting its irreplaceable features from the insidious creep of moisture-related decay. 

Meeting Modern Codes: Ensuring Safety and Compliance

Building codes evolve to reflect advancements in safety standards and construction technology. Historic buildings, while cherished, must still adhere to these codes to ensure the safety of occupants and the public. Replacing an outdated roof provides an opportunity to bring the building into compliance with current regulations. This might involve upgrading structural support, improving fire resistance, or incorporating modern insulation techniques. 

Revitalizing a Landmark

Over time, weathering, damage, and previous repairs can detract from the original beauty of a historic roof. Replacing the roof allows for restoring its original appearance, revitalizing the building's character and enhancing its visual appeal. This might involve sourcing historically accurate materials, replicating original detailing, or employing traditional craftsmanship techniques. 

A real-life Example: The Château Laurier, a landmark in Ottawa, ON

The Château Laurier, a landmark in Ottawa, ON, is one of Canada’s most iconic historic hotels. Located in the heart of downtown next to the Parliament Buildings and overlooking the Rideau Canal, this masterpiece of French Gothic Châteauesque design was commissioned by the Grand Trunk Railway between 1909 and 1912. Although its commissioning president tragically perished aboard the Titanic before seeing it completed, the Château Laurier opened to the public in 1912, officially unveiled by Prime Minister Wilfred Laurier. With its granite walls, white Italian marble, and travertine staircases, it became a premier destination in Canada’s capital.

The Need for a Roof Restoration

Over time, the Château Laurier’s distinctive copper roof began to show its age. More than 30 years had passed since the last major work, and the roof required extensive repairs to preserve the building’s structural integrity and historical character. Recognizing the significance of the restoration, Fairmont, the hotel’s current owner, brought in Heather & Little to lead the copper roofing replacement in collaboration with Cooke Engineering of Ottawa.

Restoring the Copper Roofing for the Château Laurier

The restoration was a multi-year effort spanning six years. The team installed 16-ounce standing seam copper roofing with 20-ounce copper valleys and water tables. Enhancements included a modern air vapour barrier, snow restraint systems, copper air intake louvers, and the reproduction of ornate copper elements. The challenging roof pitch and limited access required much of the work to be completed from bosun chairs, showcasing the precision and expertise of the craftsmen involved. The result was a roof that not only protects the building but also enhances its architectural grandeur.
