URGENT Help Needed: 15 Year Roof Question

[Samantha M.]

Just finished looking at a house today. Need to make an offer sometime tomorrow afternoon. The house has a 15 year roof (the "flat" looking shingle tabs) and the roof is now 19 years old, so over its life expectancy. So common sense would say, its time to replace; however, given its age its in great condition. Granules are still there, no wind damage or anything of that nature.

If you were me, based on information I have given you, would you project a re-shingle into the project or would you push it down the road a bit? My exit strategy for this property is a rental.

Trying to see if i can shave some money of my estimated repairs in the short term to get a better offer in.
