UPDATE: Contractor installed Class 3 shingles instead of Class 4 (plus siding damage). Held the $22k balance—and won

Hey everyone, wanted to drop an update here since my original post got a lot of traction and great advice.

Quick Recap: Contractor accidentally (or intentionally) installed standard Owens Corning (Class 3) shingles instead of Class 4 thatt I contractually paid for. To make matters worse, they left a jagged mess on my siding. I held 100% of the final balance ($22,000) while we sorted it out.

Here is how the negotiation went down over the last 12 hours or so:

The project manager/GM broke her silence and initially offered a $2,600 credit ($1,100 to refund their wholesale material cost savings + $1,500 to cover "insurance discount difference").

I immediately realized that refunding the $1,100 wholesale difference was just them giving back money they shouldn't have kept—it wasn't a true penalty for permanently downgrading my roof line.

Here is the kicker, I finally FINALLY got some answers from my insurance company. Now that the roof was complete they could fully quote the new premium(s). I had them quote Class 3 AND Class 4 since at the time I was speaking with them I had not made up my mind if I was going to keep Class 3 as-is or get the Class 4 installed. And guess what? After all of this my insurance actually pools Class 3 and Class 4 into the same tier, meaning the $1,500 insurance credit was free money.

So I countered with a polite email. I called out the material cost BS and noted that the GM/project manager was personally on-site the morning of the install and walked right past the wrong pallets. I anchored high, demanding a $10k credit to avoid the massive headache, stress, and heavy cost to them of a total tear-off and replacement.

The Resolution: Within a couple of hours, they scrambled and asked to meet in the middle. We officially settled on a flat $8,000.00 credit off the final bill (bringing my total due down to $14,000).

The agreement is strictly contingent on them completing the repairs that I requested, and for an extended warranty.

Once the work is done and inspected, I release the adjusted funds.

The Takeaway: Cash is king. If I had already handed over that final check, I would have had a 0% chance of getting them to care about the shingle swap or the siding damage. Holding that $22,000 gave me the leverage to get my property fixed, and keep $8k in my bank account. this was never taking it "to the man" or being a dick. Just to get the best resolution.

Thanks to everyone who chimed in on the original thread! Always check the wrapper on your shingles before they nail them down. And $$$ is king.
