Insurance Rates:
Metal roofing can also lower your insurance rates and save you money because of its fire resistance. Metal roofs boast a contemporary style, extensive warranties and are very durable. Even in extreme conditions such as fire, heavy snow and hail; metal roofs are extremely protective of your home and investment. It takes an advanced knowledge to properly install metal roofs and we pride ourselves on constantly striving to be the very best in Canada.

Energy Savings:
You can save an estimated 15% on energy savings with a metal roof. This is because a metal roof takes less heat from the sun, keeping your home cool in the summer and well insulated and protected in the winter.
Buyer’s Long-Term Savings:
There is often zero to little maintenance needed for a metal roof. This helps save money over time in not having to do costly repair jobs for patches. In addition, asphalt roof homeowners will also have to replace their roof at least three times before a metal roof homeowner needs to replace their roof once.
Environmentally Friendly:
A metal roof is the environmentally friendly decision. This is because of its long-life span, which avoids large build ups at landfills due to the short-life cycle of asphalt shingles. Choosing metal roofing also means reducing our consumption of non-renewable resources. Over time, this contributes to huge savings to the environment and planet.

Double lock standing seam metal roofing is the best type of metal roof that exists.

Double Lock Standing Seam

Double lock standing seam metal roofing is the best type of metal roof that exists. A double lock seam is a historic joinery method to lock two pieces of materials together. Long before solder or welding were ever invented, guild member tins smiths would travel from country to country throughout western Europe fastening metal buckets, cups, and castle roof flashings. Utilizing techniques similar to origami, ancient craftsmen discovered the various methodology and knowledge required to fold metal together in ways that allowed the metal to fold around complex shapes by joining different pieces of metal together using various types of folds and locks.

Today these historic techniques are referred to by craftsmen from around the world as “traditional double lock standing seam methods” or “European Guild approved double lock standing seam methods”. Although old, these methods of joining metal together remain far superior to any methodologies which relies on caulking, solder, or petrochemical sealants. One of the main benefits of double lock standing seam technology is that it allows for the expansion and contraction of the metal, because the seams can “breathe”.  This means that if thick copper sheets are used, the roof can last for over 600 years!. For example, the copper roof of St. Mary’s Cathedral in Hildesheim was installed in 1280 A.D., and survived until its destruction due to bombings in World War II; which is an impressive 662 years.

Merlin’s Roofing Co. studies these ancient techniques which have been perfected and improved upon over the last millennium. European Guild techniques are now taught by various masters throughout the world. Merlin’s Roofing Co. works closely with the foremost master/expert in Canada, Peter Steetz from Steetz Copper craft, as well as various European masters from around the world including Russia, Sweden, Germany, and more via the internet. We are constantly studying to improve our techniques so that we can be leaders in bringing sustainable, environmentally friendly, roofing solutions for the full life-span of the structures they protect. Merlin’s Roofing Co. manufactures and installs standing seam panels for all types of materials, including steel and copper.

Merlin’s Magic Lock Standing Seam

Merlin’s Magic Lock Standing Seam is a contemporary take on the traditional double lock standing seam. These panels fall into a category called “snap lock” standing seam. They are 100% manufactured by us in Canada, using only high quality 24G or 26G steel, with a 40 year paint warranty. We are able to manufacture our roofing panels on-site, or in our Poltimore, Québec shop. We can then ship them to anywhere in the provinces of Québec and Ontario.
Our steel panels come with a 40 year paint warranty. In addition to this, we utilize European Guild techniques at the ridges and around any penetrations, such as plumbing stacks and chimneys. This means that all Merlin’s Magic Lock panels are engineered to last a minimum of 100 years! Only a simple re-paint is needed at 40 years. Merlin’s Magic Lock panels can also be sold to DIY enthusiasts. The reason for this is because of the relative ease of installation and also because the specialty tools required for this are much less expensive than for other products.
Aesthetically, Merlin’s Magic Lock panels look almost identical to the traditional double lock standing seam and snap lock style standing seam panels, which are the most common type in the metal industry. Other companies, such as Ideal Roofing and Vicwest also manufacture snap lock standing seam style panels with the Heritage profile and Prestige profile respectively. In comparison to other manufacturers though, Merlin’s Magic Lock Standing Seam panels have some key benefits.
First, we only use high quality 24G and 26G steel, which is very thick and resistant to fire, hail, trees/debris and wind damage. Other companies use 28G and 29G in their products, our 24G and 26G steel is more than 60% thicker! This translates to a far greater protection for your home and investment. We also offer our panels at competitive rates to other manufacturers who would otherwise offer a thinner metal, thus enabling a better product to be sold to the customer. Another advantage of Merlin’s Magic Lock panels is that they utilize a floating clip system. This means the panels can expand and contract freely. Other manufacturers use an integrated “nail strip” which is attached to the panel and does not allow for thermal contraction. As a result, this is primarily responsible for metal fatigue and premature roof failure. Merlin’s Roofing Co. offers our Magic Lock panels as fully installed systems or as a supplier of materials only, to DIY enthusiasts and other roofing contractors.
