Kasselwood Permanent Roofing : FAQ


Below are some questions we have been asked in the past, and our answers to them.

How does a metal roof compare in cost with other roofing materials?

A Kasselwood permanent roof is an investment in your home which provides an immediate and ongoing increase in home value. While it has a higher upfront cost (2 or 3 times asphalt price), homeowners who plan to remain in their home through at least one re-roofing cycle (usually 7– 12 years), will see a significant financial benefit from a Kassel & Irons roof that will not have to be replaced during that time or even long after. Our roofs will also save you money on ever-increasing home energy bills as well as costly and messy re-roofing with temporary roofing products.

How much longer will a Kassel & Irons roof last in comparison to common roofing like asphalt or wood shingles?

With temporary roofing products, your roof starts to deteriorate the moment it is installed. According to the asphalt roofing industry, the average lifespan of traditional shingles is 7-12 years! Heavily pro-rated or limited warranties on these products bring little or no value to property owners. Wood shingles also deteriorate quickly. Our roofs carry meaningful long-term warranties on both the base metal and their high-quality coatings. We invite you to read the details of our warranty – we believe it is solidly the best in the industry!

Will a Kasselwood roof rust?

Our premium KasselWood roofs are made of 29 gauge galvanized steel. The galvanizing process has been proven rust inhibitor for more than 300 years. Couple this with the latest protective coating technology makes a Kasselwood permanent roof a rust free system.

Are our roofs heavier than other roofs?

Here’s a comparison:

  • KasselWood Shingles: 85 lbs./square
  • Standard Composition Shingles: 210 lbs/square
  • Cedar Shake: 220 lbs/square
  • Architectural Shingles: 340 lbs/square
  • Slate: 600 – 700 lbs/square
  • Clay/Concrete Tile: 600 – 1000 lbs/square
Will the color fade over time?

KasselWood’s color palette uses PPG’s Duranar UltraCool advanced paint system. Combined with Kynar500 coatings, each KasselWood steel single comes with a 30-year fade resistant warranty making certain that your roof colors will remain vibrant for decades.

Is underlayment used beneath a steel roof?

First of all, our roofs require solid decking. Whether the job is over old shingles or direct over wood decking, underlayment should be used. 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.

Can we walk on it?

Our high-strength steel combined with deep texturing, doesn’t lose strength over time, making our roofs just as resistant to foot traffic and even hail when they are many years old as they are when they are new.

Can you install attic vents on a steel roof?

For most homes, attic ventilation is critical. It helps avoid unhealthy high moisture levels which can result in condensation and even mold. It helps reduce home heat gain and air conditioning costs in warm weather. And it also plays a huge role in avoiding winter rooftop ice dams in northern climates. So, yes, your Kassel & Irons roof can, and usually should be, vented. Most commercially available roof and ridge vents can be incorporated into our roof systems. When a home is being re-roofed, we suggest that all vented be replaced rather than re-used.

Can skylights be installed with my Kassel & Irons roof?

Yes. Normal types of protrusions through the roof do not pose a problem. They need to be flashed and detailed properly. Skylights must be curbed, not flush-mounted. If there are existing skylights that show deterioration or if the existing skylights are 10 or more years old, we suggest new skylights be installed. Even the best skylights have 20 year warranties. It does not make sense to install a long term roof with a skylight that will soon need to be replaced.

What will happen to a metal roof in a lightning storm?

Lightning occurs from the highest object in an area, regardless of the material from which it is made. Metal roofing does not create nor attract lightning and poses no additional lightning risk to the structures it protects.

What about hail?

The heavily-textured beauty of our metal shingle roofing systems adds strength and prepares them to take whatever Mother Nature 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.

What about fire?

Steel roofs are non-combustible and provide great protection from external fires. Additionally, the extreme low weight minimizes any cave-in threat which might occur in the event of an interior house fire.

Will a Kasselwood roof offer energy savings ?

Yes. A Kasselwood roof has a higher energy efficiency than another roof because it’s a cool roof. Kasselwood shingles use PPG’s Duranar Ultra Cool® advanced paint system offering more heat reflectivity than virtually any other roofing material available. This allows to keep the roof cool, even with a dark color, and reduce the temperature into the attic and the house.

What is the difference between buying a Kassel & Irons steel roof and purchasing sheets of metal roofing through a national home improvement chain?

Homeowners who purchase big box products can be severely disappointed by the lower quality metals, coatings, and product designs they purchased. By choosing Kassel & Irons, you are assured top-quality products, serviced and installed by the best. Many of the “big box” products also have exposed fasteners rather than concealed fasteners.

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. In comparison, temporary roofing materials use up precious natural resources and pollute the earth by sitting in landfills.
