We use new breathable underlayment standards on all roof pitches 7/12 and under (owner may request on steeper pitches), resulting in virtually no callbacks.

Ice and water shield is installed under all bathroom fan vents and plumbing flashings.

Valleys are pre-finished metal (black or brown) with ice and water shield underlayment.

All vents are steel and pre-coloured. Extra vents will be added as required per sq. ft.

If your roof needs more soffit ventilation, plywood or boards will be removed, and Moore (baffle) vents will be installed. This will help your roof breathe properly.

We carry full liability insurance; all roofers are certified in Working at Heights and Basic Supervision Training.

Metal Roofing

Metal roofing is a durable product that can withstand strong winds, pounding rain, scorching sun, and more. Metal roofs are easier to maintain as debris is easier to sweep off, and they are not as flammable, an increasing concern as wildfire season gets more intense yearly. Goreski Roofing is experienced in installing and repairing metal roofing systems. To request a quote, please give us a call.

Here are the benefits of metal roofing:

  • Durability
    Metal roofs are renowned for their exceptional durability. They can withstand extreme weather conditions, including heavy snow, hail, and high winds.

  • Longevity 
    Investing in metal roofing is similar to a long-term investment in your property. With a lifespan that can easily surpass 50 years, metal roofs often outlast conventional roofing materials by decades.

  • Energy efficiency
    Metal roofs are highly reflective, efficiently reflecting the sun's rays and preventing excess heat absorption. This lowers energy bills as your home or business stays cooler in summer. 

  • Environmentally friendly
    Metal roofing is one of the most eco-friendly roofing options available. Many metal roofing materials are recyclable, reducing the environmental impact. 

  • Increased property value
    The durability, longevity, and energy efficiency of metal roofing can significantly enhance the value of your property. Potential buyers often pay a premium for a home or building with a durable, low-maintenance roof that will last generations.

Flat Roofing

Flat roofing is a common system for commercial buildings. Flat roofs often come with lower construction and repair costs. There is a wide range of flat roofing systems, and Goreski Roofing can install and maintain many of them. Please give us a call today to request a quote.

The benefits of flat roofing are:

  • Cost-effectiveness
    Flat roofing is often more cost-effective to install compared to pitched roofs. The materials are typically less expensive, and the installation process is generally quicker. 

  • Versatility
    Flat roofs provide a versatile platform for various purposes. They can be transformed into usable spaces such as rooftop gardens, outdoor lounges, or even solar panel installations. This versatility allows homeowners and businesses to maximize the functionality of their property.

  • Space efficiency
    Unlike pitched roofs, flat roofs do not have steep slopes that limit interior space. This design allows for more usable space within the building landscape.

  • Accessibility and maintenance:
    Flat roofs are easily accessible, making inspections, maintenance, and repairs more straightforward. This accessibility means that issues can be identified and addressed easily.

  • Aesthetic 
    Flat roofs offer a modern and sleek aesthetic that can enhance the overall look of a building. They can be designed with various finishes and materials to complement the architectural style.



Shingles are the most common type of roofing. They’re versatile, cost-effective, and energy efficient. Plus, shingles come in a variety of styles and colours. We provide repairs and replacements for residential shingle roofs. Give us a call today for a quote.  

The benefits of shingles are:

  • Weather resistance
    Shingles are designed to offer excellent protection against harsh weather conditions, including rain, wind, hail, and snow. They are engineered to provide a reliable barrier during severe storms.

  • Easy repairs and maintenance
    In the event of damage, individual shingles can be replaced relatively easily, making repairs straightforward. This means that maintenance and upkeep are convenient.

  • Energy efficiency
    Certain types of shingles, such as asphalt shingles with reflective coatings, can help improve your home's energy efficiency. By reflecting more sunlight and absorbing less heat, these shingles can contribute to lower energy bills.

  • Cost-effectiveness
    Shingles are a cost-effective roofing option compared to some other materials. Their initial installation cost is generally lower, and their long lifespan ensures excellent value for your investment over time.
