We did our house with steel. The insurance company knocked off 150.00 a year on our home owners policy.

My father grew up in a house with a slate roof, built in 1930.
House is now owned by a cousin and the slate roof is still good.

In 1984 my mother wanted to buy a newly built house with a cedar shingle roof, as were all nearby houses.
My father went along with her wishes but said many times: “Cedar shingle roof is a fire hazard and will not last long.”

In 2014 we replaced the cedar shingles because we were worried about the underlayment,
but it turned out all the original plywood was good.
Cedar shingles could have gone 5 more years, maybe slightly more.
There are still 2-3 houses in the sub-division with cedar shingle roofs, but 90% have been replaced with asphalt shingles.

4 years ago a hailstorm damaged over 20 of these new asphalt shingle roofs nearby which were replaced and paid for by insurance claims.

I just paid $242 a square for tearing off three tab and installing a Certanteed heavy laminate. Those three tabs are useless in windy west Texas. I think I got a good deal. He charges the same for three tab because the labor is harder. Even though the laminate cost more in material.

approximately 1800sqft garage and house done with steel because our 1872 original slate on the house finally gave out in multiple places, and we couldn't find anyone to repair it.
it cost a tick over 12k, which also included an addition to the roof over our deck.
we are very happy with it because it's the type of roof [i forget the name of that style] that has no exposed fasteners that could potentially cause a leak in the future.
it is also one of those "one piece" deals, in that the crew had a machine on site that formed the coil[s] to the exact length and shape needed for each piece.

Just had my 40 sq Architectural roof removed and replaced with 40 year Architectural shingles $11,000. Removed replaced and cleaned up in a day. Dumpster was on property less than 24hrs. Well worth the price.

I sometimes think these roofing companies just pull a number out of the phone book.

I've forgotten the exact size of our roof but I seem to recall it was about 30 sq +/-.

We did it about 5 yrs ago and I was getting quotes for 30 yr shingles in the $10k range installed. If you put 30 yr shingles in the house instead of on the roof you still can't get 30 years out of them. At the time shingles were about $70 a sq. I could buy steel from a supplier I knew for similar money so it's a no brainer. Called a couple of contractors to quote just the install and it's STILL $10k and I'm supplying the steel and all the assorted doodads.

I see an ad for a steel roof installed all in for 2.60ish a sq ft. He measures it up and we pick the color and profile, $8100.

Typical roofer, he says it will be done in August and he shows up in December. Lol. Did an excellent job, cleaned up all the mess and repaired a rafter and replaced part of a sheet no charge.

Best of all, it don't leak anymore.

Retired May 1st after 28 yrs in the insurance industry.. The last 11 as a catastrophe rep. Every region of the country that I worked roofers would install architectural shingle for the price of a 3 tab. Last place I worked cost was $250-265 a sq.
