When maintenance is no longer an option for your roof, proper planning for replacement is critical. As a certified and experienced installer of all roofing products and systems, Semple Gooder will review your specific requirements to develop the optimal roofing system for your facility. Our goal is to deliver durable and long-lasting roofs to our clients while minimizing impact to operations and keeping buildings safe and watertight throughout the construction process.

Many of our re-roofing operations occur over occupied spaces in industrial centres, or difficult to access roofs ranging from historical buildings to high-rise towers in the urban core. For over seventy years owners have trusted Semple Gooder with their re-roofing needs.

New Roofing

  • Multi-use Industrial, Commercial & Institutional
  • Automotive Facilities
  • High Rise
  • Education Facilities

Gambling with inadequate roofing can lead to a costly lesson. Professional experience and demonstrated skills are a priority when installing a new roof. While there are a myriad of roofing systems on the market, we install and warrant only those that have proven performance.

Our professionals choose the most appropriate system and proper specifications to accommodate client requirements, which are then carried out by our certified tradespeople with detailed accuracy, ensuring a weathertight solution.

Historic restoration will restore a building to its original sound, serviceable condition when undertaken properly. A detailed survey will identify locations of the roof where the building has had problems over time. Modification of those locations will allow the building to perform better in the next several decades, while leaving other details similar to the existing where no concerns are present. A combination of traditional and modern materials and techniques are incorporated to improve on the traditions that have stood the test of time. A flexible, co-operative teamwork approach with Semple Gooder will address unique site conditions, while attaining success for the building project. Our historical roofing and sheet metal division is one of the most well respected companies in this field and has delivered landmark projects. We employ only the most skilled craftsmen with generations of experience.


  • Vegetative Plantings
  • Cool Roofing
  • Sustainable products
  • Lightweight Insulating Concrete
  • Solar

With so much available roof space in cities, Green roofs represent opportunities with significant social, economic and environmental benefits. Green roofing is commonly associated with several types of vegetative plantings. The term green roofing is also used to indicate roofs that use some form of “green” technology, such as a cool roof (white or solar reflective), sustainable construction assemblies or a roof with solar photovoltaic panels. Cool roofs reduce both building cooling loads and the urban heat island effect. Solar paneled installations minimize our dependency on non-renewable energy sources and also reduce the negative effects of carbon-based emissions. Sustainable construction assemblies (Lightweight Insulating Concrete) significantly reduce the impact on landfills and optimize the life cycle performance.
