Okay, I need to replace the shingles on the house. I don't want to do it. I already fell off once. Here's what I'm dealing with.

It's 40 feet long and 28 feet deep. 12/12 pitch. I just got a quote for $14K for 40 year shingles, $15K for 50 year shingles and $28K for seamless steel. This all seems completely out of line to me. Tell me what you know.
You should really take the shingles off and inspect the wood underneath.
Construction is expensive:
Cost of skilled labor
Permits AHJ
Insurance
Contractors license
Skyrocketing price of wood materials. There has been considerable increase lately.
Delivery of materials.
And on top of this, contractor must also make a profit.
You would probably benefit from increasing the thermal and moisture barrier underneath the shingles.
Newer materials could help drop your heating costs considerably and save a lot of energy.
I would investigate whatever is available to upgrade and weigh cost VS energy consumption, before calculating a final price.
Yes I have been to contractor management school / college.
But it really makes you realize that there is a lot more to it than you see on the surface.
The costs are a lot higher when you add in everything / calculate energy efficiency, etc.
When this roof was built -heating cooling costs were ridiculously low.
Now energy costs are multiplying, and there is a serious need to predict future operating cost VS materials used, and what advantages you could gain.
