Up to now, you have made all the right decisions. The roofer's estimate should clear the way for you to make an informed decision on how best to proceed.
It may be time for your RE agent to step up and help negotiate an amount that doesn't leave you "holding the bag." You'll likely hear that as long as the present roof is not presently leaking a replacement is not necessary or that a patch or easy repair will take care of the problem.
Be sure to get a written evaluation from the roofer that speels out the nature of the problem, scope of work needed to correct the problem, cost for the work to be done, and most important of all....their recommendation. It would certainly help your cause by having more than one contractor providing the same recommendation.
Right now the problem belongs to someone else. Make sure that it doesn't become yours.....
Take the highest work proposal and ask for this amount as credit from the sellers. By the way, are you working with a real estate agent? They should have recommended this for you.
Why are you not speaking to your agent about this? Also, your mortgage professional should be able to help with the credit limit answers.
I would recommend getting a few different roofing bids. As far as the roof being a deal breaker, what do you think. If the seller gives you a credit do you feel you are prepared to move forward and get the work done yourself? You can always request that the seller do the work prior to closing. Then you could have an inspector reinspect the repair work. Negotiating repairs can be stressful. I hope that this helps.
