In GA due to hot and cold weather extremes the roofs expand and contract and wear out much faster than the warranties.How many layers of shingles are on the roof now??

The tree it turns out roughed up the roof a bit so we trimmed it and repaired some shingles. 

I was jumping back & forth between dimensional shingle & tile.  

Asphalt shingles leach material during rain storms, and can leach material not great for ground water. 

Looks to me like it could use new shingles, new paint, new landscaping, etc.

I am going to be using LP smartside instead of vinyl siding which is going to cost an extra $3,000-$4,000.I suppose when I build a spec house I would opt for asphalt shingles ($1.50/square foot) and do good double pane windows for half the cost of triple pane and still have it be good quality, energy efficient, and attractive.  

But taking a closer look at the inspection report, there appears to be a lot of issues and defects in areas that I wouldn't have expected for a newly rehabbed property, which calls to question their quality of work.For example, the report found some shingles damaged on the roof, but the roof was supposedly new?

If anyone needs a roof fixed or a new roof altogether, I can get really good deals..my guy does high volume so they can afford to give 130 mph architecture shingles at the same cost of 3 tab 60 mph shingles. 

A new upgraded arch shingle roof last year.

That's probably not too far off right now. 30 year shingles at Lowes before tax are running about $110/sq, add in your felt, nails, sealant, tear off/lay down labor and I'm not shocked by your quote.
