There are only 2-3 companies that make shingles in the US. For the most part poor installation does not affect life of a shingle

You can buy the shingles to do 100 square feet for $120, so it’s $480 for labor? That probably come to $300-$400 a man hour. Lucrative business. I had a 3 bedroom double (6 bedrooms in all) in Ohio done for $5200 last year.

If your true interest is cost let me, make a suggestion.
A few of my neighbors and I had our roof down before Milton hit.
Our roofs stayed intact, other neighbors who did not have the work done suffered damage.
My whole deductible was $500 from Farmers Insurance, some of my neighbor paid a bit more.
But after Milton damage countless roofs, the cost of repairs skyrocketed.
If you did not suffer damage, you should wait until the demand subsides.

I thought architectural shingles were the standard shingle in The Villages. They have a 3-D appearance. If you installed flat, non-architectural shingles, your house would stand out like a sore thumb, and I doubt that ARC would allow them. Am I missing something?
