Costs and Lifespan

Does a Metal Roof Cost More Than a Traditional Roof?

Metal roofing is an investment in a maintenance-free, durable roof that comes with a rock solid lifetime warranty. Although the cost of a traditional asphalt shingled roof may be a fraction less upfront, costs grow over time due to regular maintenance and the need to ultimately replace within 10 to 15 years, especially in a climate like Alberta’s. This roof pays for itself over time and it adds value to your home. It’s the last roof your house will have.

Will I Save Money on Utilities?

Metal roofing is a fantastic way to add much greater climate control to your home. KasselWood Metal Shingles are coated with BASF technology with a reflective pigment making it a cool roofing system contributing to a much more environmentally responsible living space.

How Much Longer Does a Metal Roof Last Compared to Other Materials?

Supreme Roofing Solutions offers the full line of KasselWood Metal Shingles and roofing materials that are engineered to last a lifetime, come with a lifetime warranty, and have received the highest ratings for resistance against wind uplift, fire, hail, and snow. Metal roofing stands up to even the most extreme weather in Alberta.

Will a Metal Roof Rust Over Time?

KasselWood Metal Shingles are made of 29-gauge galvanized steel, which has been third-party tested and certified to inhibit rust for hundreds of years. Today’s metal roofing systems are built to last. Steel metal roofing has a “metallic coating” made of either zinc or a combination of zinc and aluminum. This metallic coating prevents rust from forming and is bonded to the steel at the factory.

Will a Kasselwood steel roof last long than common roofing products such as asphalt and wood?

Asphalt and wood shingles are temporary roofing products. When used, they begin to deteriorate the day of installation. The asphalt roofing industry sets the average life of a traditional shingles at 12 to 17 years. Heavily pro-rated or limited warranties on these products bring little or no value to homeowners. Wood shingles deteriorate quickly, too. A Kassel & Irons steel roof carries a long-term warranty on both the base metal and its high quality coatings. You can expect our steel roofs to last for a lifetime.

How will the penetrations, such as skylights and roof vents on our metal roof be flashed?

Many roofing materials are heavily dependent upon sealants to seal around chimneys, skylights, attic vents, and pipes. While sealants will be used on your metal roof, they should not be the sole line of defense against water intrusions. We will ensure long term performance without sole dependence on sealants.

Is underlayment used beneath a steel roof?

All of our roofs require solid decking. Whether the installation is over old shingles or directly over wood decking, underlayment should be used. Roofing underlayment is required by the International Building Code and it helps protect the back side of the metal from any rough surfaces below the roofing material. Generally, one layer of synthetic underlayment is used or one layer of 30-pound felt. In certain areas, as required by code, ice and watershield products or fire-retardant underlayments will be used.

Installation

Can I Customize a Metal Roof to Fit my Home or Business?

The answer is yes! KasselWood steel shingles are crafted for maximum curb appeal. Authentic detail produced a visually stunning roof that enhances the beauty of any home or business. You will love looking at your roof as it stays fresh in appearance over the long term. Metal roofing comes in more design options and colors than ever before and can be cut to fit any style or design. Just take a look at one of the hundreds of properties we have serviced throughout Alberta.

What is the minimum roof pitch on which a Kassel & Irons Roof may be installed?

No roof should ever be installed at a pitch lower than that recommended by its manufacturer. Our metal shingle products require a 3:12 pitch. If you have a roof section that is lower pitched, standing seam roofing solutions are available for that area and can usually be used down to 2:12 pitch.

Why not just go to a Big Box home improvement store and purchase metal roofing for my home?

At Supreme Roofing, we are dedicated to providing high quality, beautiful, and durable product that last a lifetime. Homeowners who choose to purchase “big box” products can be disappointed not only in the performance of the metal roof, but in the installation process, lack of color and finish selection, and certainly in the warranties offered. We know Alberta, and we install the Kasselwood metal roofing products that are best suited for Alberta homes and businesses.

Weather

How much rain noise can we expect on a metal roof?

Our steel shingle products are textured, and avoid much of the noise expected from rain hitting a a flatter metal roof. For normal construction methods, steel roofing does not create any objectionable noise during rainstorms. Ventilation and attic air space have an impact on sound absorption, as can roof roof underlayment materials.

How does a steel roof handle hail?

The heavily-textured beauty of our steel shingle roofing systems adds strength and prepares them to take whatever the weather dishes out. Our warranty provides specific hail protection including protection against finish damage and leaking due to hail. Additionally, unlike most other roofing materials, metal does not lose impact resistance with age – this is a real bonus over other products which become more susceptible to damage with each passing year.

Because of our Class IV UL 2218 Impact Resistance Rating, you might even be eligible for a discount on your homeowner’s insurance. In the event of an especially severe storm, if an indentation does occur, it can often be repaired easily and invisibly by capping over the damaged shingle panel with a new panel.

Will a Kassel & Irons steel roof attract lightning?

Metal roofing does not create or attract lighting and poses no additional lightning risk to homes and other structures it protects. For more information on this subject, here is a technical bulletin from the Metal Construction Association.

What about fire?

Steel roofs are non-combustible and provide great protection from external fires. The extremely low weight of a steel roof minimizes any cave-threat that might occur in the event of an exterior house fire.

Miscellaneous

Will gutters be used with a steel roof?

Yes, gutters (eave troughs) can be used with steel roofs. In most cases, our advice is to use a heavy duty gutter such as a 6” K-Style gutter produced from .032” aluminum. Additionally, we advise hanging the gutters as high as possible, with appropriate pitch for drainage.

In order to avoid interference with the roof system, gutters should be installed using fascia-mounted brackets. If necessary, the roof system drip edge can be notched to allow for the brackets. The drip edge should always direct water into the gutter. Many of the gutter protection and cover systems can also be used with metal roofs though our preference is for leaf control systems that sit inside of the gutter and, again, do not interfere with the roof system.

Will a metal roof interfere with phone reception and other electronic transmissions inside my home?

If you have fair to excellent cell phone reception and internal system signals within your home now, a metal roof should not have any noticeable effect. Chances are that you currently use your cell phone and other devices inside of metal roofed buildings now, such as restaurants, stores, your bank…maybe even your workplace. Your home environment, with a metal roof, should be about the same.

Can we walk on a Kassel & Irons metal roof?

Our high-strength steel, combined with deep texturing, don’t loose their strength over time, making our roofs resistant to foot traffic and even hail, even as they age. Your product representative can give you instructions on how to safely walk on your roof. It is also important to note that the random texture of our steel shingles will mask any minor indentation that may occur.

What happens when dirt collects on my metal roof?

The PVDF coatings used on quality metal roofs consist of a very tight molecular bond that encourages dirt to wash off of the roof. In most environmental conditions, these roofs stay very clean over the long term. However, while these coatings will not support the biological growth that leads to dark streaks and stains on granular surface and shingle roofs, there are certain environmental conditions which can cause dirt to collect on the roof. The worst situations are in areas with surrounding trees, and this is made worse by trees that lose sap which can stick to the roof and then hold dirt or even support biological growth over time.

Additionally, heavy pollen or airborne fungus can land on a roof and stick there. Areas prone to heavy and frequent dew (such as waterfront or near-waterfront properties) can also exacerbate this issue by creating a sticky or gummy coating on the roof. We always tell folks to imagine letting your car sit out in the area of your roof and not washing it. The results on it, over time, will be similar to what will happen on your roof. In some cases, folks like this because it helps the roof to take on a more “woodsy” or “natural” appearance. The resulting grime on the roof, while it can be cleaned by scrubbing or light power washing, will not normally be something that damages the integrity of the roof system or its finish.

Is a Kassel & Irons roof environmentally-friendly?

Our roofs are made from 35% recycled steel and their long life expectancy guarantees sustainability. Add in energy efficiency and the ability to be installed over most existing roofs (avoiding landfill disposal of old materials) and you have a very environmentally-friendly roof that can be a major contributor to LEED points. In comparison, temporary roofing materials use up precious natural resources and pollute the earth by sitting in landfills.
