Welcome to our FAQ section, where we address common queries and concerns to provide you with comprehensive information about our products and services. Whether you’re curious about installation processes, maintenance tips, or product specifications, our FAQ section is designed to offer clear and concise answers to help you make informed decisions. Explore our frequently asked questions to find valuable insights and solutions, and feel free to reach out to our team for further assistance.

How Long Do Metal Roofs Typically Last Compared To Traditional Roofing Materials?

Compared to traditional roofing materials, metal roofs are the clear winners in the longevity department. While asphalt shingles, the most common choice, typically last 15-30 years, metal roofs boast a lifespan of 40 to 70 years, with some champions like copper lasting well over a century. This impressive durability stems from metal’s resistance to harsh weather, rot, and insects, making it a low-maintenance option that keeps your home protected for decades.

How Can I Choose the Right Metal Roof Colour for My Canadian Home?

Selecting the perfect metal roof colour for your Canadian home involves several practical considerations beyond just aesthetics. The colour you choose can impact your home’s energy efficiency, maintenance needs, and overall curb appeal. Lighter colours like white or light grey reflect sunlight, keeping your home cooler in the summer and potentially reducing cooling costs. However, darker colours like brown or black can absorb more heat, providing passive solar heating in colder climates but potentially increasing cooling costs in the summer. Understanding your climate, considering maintenance requirements, and ensuring compatibility with your home’s architectural style are all crucial factors in making an informed decision. Consulting with a qualified metal roofing contractor can provide tailored guidance to help you choose the ideal colour for your home.

Are their energy saving benefits associated to metal roofs?

Yes, there are significant energy-saving benefits associated with metal roofs. Metal roofs are highly reflective, meaning they can effectively reflect solar heat away from the building, reducing the amount of heat absorbed into the home. This reflective property helps to keep the interior of the building cooler during hot weather, reducing the need for air conditioning and lowering energy costs. Additionally, metal roofs can be installed with insulation materials, further improving energy efficiency by reducing heat transfer between the interior and exterior of the building. Overall, metal roofs contribute to lower energy consumption for cooling, making them an environmentally friendly and cost-effective option for homeowners.

How to Choose the Perfect Metal Roof for My Region?

Selecting the right metal roof for your home involves considering various factors tailored to your specific region. Understanding your local climate and weather patterns is crucial, as it influences the type of metal, coatings, and finishes best suited for your needs. Additionally, assessing local building codes and HOA regulations ensures compliance with guidelines regarding materials and styles. Considering the aesthetic appeal of different metal types and understanding their pros and cons helps in making an informed decision. The roof’s pitch and style, energy efficiency, environmental sustainability, installation costs, longevity, and maintenance requirements are also essential considerations. By prioritizing practicality, aesthetics, and expert advice, you can choose a metal roof that not only protects your home but also enhances its curb appeal, tailored to your region’s specific needs.

Why Should I Choose Professional Metal Roofing Installation?

When it comes to installing a metal roof, opting for professional installation offers numerous benefits that can help you avoid DIY disasters. Professional roofing contractors prioritize safety, ensuring that the installation is conducted securely and efficiently, reducing the risk of accidents or injuries. Their expertise and attention to detail guarantee high-quality workmanship, ensuring that your metal roof is built correctly the first time and lasts for years to come. Professional roofers also have access to specialized tools and equipment, expediting the installation process and saving you time and effort. Additionally, they can enhance your metal roof’s energy efficiency and ensure its longevity and durability, providing you with a long-lasting, low-maintenance roofing solution that protects your home effectively. Say goodbye to DIY catastrophes and welcome a stunning, durable metal roof with professional installation.

We had a great experience with this company. The price was competitive, and the roof looks great. The installation process went smoothly and on-time. Special thanks to John O., who took the time to answer all my questions in an honest and straight-forward manner.
Nadine Charrington
Love our new steel roof from GMR. Mike our sales person was friendly, knowledgeable, and very helpful in choosing the best style. The installation crew of Serge, Anthony, and Deidrich…the best. They took time to answer questions, explain what they were doing, and clean up was amazing. I highly recommend GMR as the first and only company to call. Thank you.
Kim Voisey
Absolutely would recommend this company…
Beatrice Amenyo
We got our roof done by Green Metal Roofing and Manufacturing Inc. recently. The GTA manager John, and their installation team (Paul, and company) did a fantastic job. They answered all of our questions, friendly service, and overall we love it! I highly recommend them!
Jeff Lee
I highly recommend Green Metal Roofing and Manufacturing Inc. Their staff is very professional, courteous and knowledgeable. The workers did a fantastic job and ensured the surrounding area is clean of all debris daily. Also, they finished the job as scheduled on time. You couldn’t ask for a better company. John Olczak came out, and his knowledge of the product made me feel at ease that I am selecting the right company. He came back after the job was completed and did a final inspection. We are delighted with our new roof.
Brian Canham
Salesman John and his team of installers were excellent to deal with and did a great job installing our new metal workshop roof at Highland Yacht Club. They were clean, efficient and honoured their install date as promised. I would highly recommend them for a metal roof installation.
Ivan Wong
Green Metal roofing was absolutely wonderful to work with from initial contact to completed installation of our metal roof. Everyone from their company was friendly, professional, knowledgeable, and accommodating. Ray, who was our first point of contact, was always willing to meet with my wife and I when it worked best with our schedule. The installers that they sent, Handel and Malik, both did a great job with the installation. It took them fewer days than predicted to complete the job, and they even helped us put in a few new lightbulbs on the underside of the roof while they were up there. And finally, Greg made sure everything regarding payment, delivery of the materials, and the timelines for installation were well coordinated, shared with us and followed up on when needed. We could not recommend Green Metal enough if you need a new roof installed.

Had my roof done about 4 years ago salesman knew exactly what to say genuine and honest. Delivery and installation was prompt to the quote two guys did the installation amazing brothers prepped and started it one day and completed it the next I mentioned this because I've seen other people in my neighborhood get similar metal roofs from other companies and it takes five or six guys five or six days to do the same size roof I would strongly recommend this company
J Shan
Got my roof done in the summer of 2022, the service was great from that start. Greg H. provided all the details in a timely manner with utmost professionalism. The install team was superb as well; Eric, Dave & Rob. Price was competitive and would highly recommend them to anyone looking to get a new metal roof.
Paul Wornham
Green Metal Roofing installed a beautiful new roof and eavestroughs on our home this fall. From the sales experience with Ray to the installers, Dave (roof) and Abe (eavestroughs), we couldn't be happier with the new roof. Our home has never looked so good and we're worry free for the rest of our time in the house. Thanks Green Metal!
