Another great testimonial for Interlock metal roofing, Bloomington, Minnesota

It’s All About the Details

A roofing system is only as good of what all the components are made of.

Video testimonial:

After noticing a leak, replacing hand-split cedar shakes on his roof was an immediate priority for a retired engineer in Bloomington, Minnesota. The quality of the all the components made Lloyd very happy.

“Details are the difference between good stuff and great stuff. “

– Stephen Brewster

Homeowner Lloyd W. was very pleased with the quality of the components we use on all our Interlock® Lifetime Roofing Systems, especially looking at that quality from the viewpoint of a mechanical and design engineer.

With much craft and care Lloyd designed and built his own house.

He expected his hand-split cedar shakes to last about 50 years. They lasted about 30.
And the garage, which he built first, is where he noticed the first leak.

Now in research mode for roofing materials he was considering including stone-coated steel, Lloyd discovered aluminum roofing companies were now very much in the mix.

After comparing all the different products, Lloyd found the reason we love aluminum. It does not rust like steel.

Lloyd explained, “I was becoming partial to the weathering effect and the corrosion resistance of aluminum. I couldn’t find any alternatives, even steel.”

He continued “They gave me a lot of assurances of how good the coating was (with steel) and how long it would last… yeah, maybe it will last for 50 years, but the aluminum I know will last virtually forever.”

Lloyd has a good story on why he feels that confident in aluminum in the video.

Home Repair for the Holidays

The Installation

Lloyd had a very pleasant early holiday gift when the installers came to install his roof even though the winter weather wasn’t ideal.

“We had a rough patch of winter before Christmas last year, and getting into the holidays the weather didn’t look good at all, and we had decided to wait until the 1st of the year, and on the 21st at 7:30am in the morning, the installers showed up and wanted to take my roof off, we decided ‘let’s go for it!’” said Lloyd.

“We had some tough weather in there, we had the holidays, we had wet snow, we had dry snow, we had the shortest days of the year … both my garage and house are two storeys…”

“I put the original roof on so I know what it’s like to work up there … but with moss coated shake … and around freezing weather, it had to be tough working up there.”

“Al and his guys did a fabulous job.”

“It did take them 10 days, and I couldn’t be happier.”


The Details

As a retired engineer, Lloyd was fastidious about the details and was happy to uncover the very high standard of quality we use for *all* our materials.

“Most people aren’t engineers like me, and probably aren’t interested in details like these … but one thing I was pleasantly surprised about with Interlock was the quality of the fasteners and the quality of the underlayment that they used … the ice guards, the quality of the snow guards… they are cast metal, the fasteners were stainless steel…. I couldn’t find out from anyone (the competition) if they used stainless steel or not… (and) are the materials you use to fasten stuff on are going to be as rugged and reliable over the long term as the main roof? I was probably the exception in wanting to know that, but I did spend a long time looking for information … but I was pleasantly surprised with the quality of the fasteners that Interlock used… and I couldn’t be happier.”

The Cost.

When getting quotes, Lloyd ran into some frustrations.

With a competing metal roofing company Lloyd said “their price wasn’t competitive I didn’t think”.

The roofing company offering stone-coated steel wanted Lloyd to “replace the skylights, which I didn’t think needed to be replaced.”

Even though the quotes were about half the price Lloyd noticed asphalt in his neighborhood wasn’t lasting as long as it used to. “I’ve noticed that some asphalt roofs put on 15 years ago, are lucky to last 15 years.”

“…and with inflation, even though it’s low now, prices go up … so it’s important not to have to replace it for a long time.”

With his mind set now firmly on aluminum, Lloyd said “I found alternative prices that were the same but I felt Interlock, with the aluminum, was superior.”

“looking in the economics of replacement, and the reliability, and the comfort level of knowing what you’ve got on there …”

“I think a lot of people look for the cheapest alternative first … then don’t (think about) all the aspects that I did …”


Fact. In 1994, over 5000 original steel window frames of the Empire State Building were replaced with aluminum frame. The 1930 original steel frames had deteriorated, allowing for frosting, water and air leakage. –

How the new roof looks.

“I wished it showed more. I’m on top of a hill, and it’s a two storey garage and house, so unless you really look for it … it’s hard to see it.”

Final thoughts

The single biggest thing Lloyd is happiest about his new roof?

“Everybody always looks at the shingle.” but Lloyd expressed that he was most happy about
”(the) way that they flashed everything. All the flashings were around chimneys, the gable ends, the eaves … the quality … the size of them, and the fact that they were the same material thickness … I know it protects my fascia boards a lot better than the original stuff I had on it.”

“They did a tremendous job on it.”
