@Eric CreagerI dont know of a specific resource but in general you want to look at the big ticket items first.Foundation - cracks, settling, moisture (basements)Roof - age remaining life, condition- missing shingles, leaks improper valleys and flashing Hvac -age useful life left.

Inspection report says :The shingles appear to be nearing the end of their serviceable life.Sealing of all roof penetrations is recommended.Is this a major item and should I negotiate on price or request the seller to fix it.

Is maintain moisture area a home that diffcult?

Don't get the engineered stuff because if you puncture the veneer and moisture gets in it, it will buckle and swell.

The water mitigation company has now expressed concerns that moisture may be seeping into the wood strut wall foundation from the outside (their numbers of saturation went up during a rain storm).

Basically the company will close off the known penetrations and slightly pressurize the tank.  

Both leaks are nowhere near penetrations!

Corporate protection can be penetrated by good lawyers for many reasons.

A contractor may tell you it will last as long as block and could be true, it's a cost savings to build wood but to me all the moisture is there and could be a problem in the future.

Even though the plank itself is reasonably waterproof, the glue and the seams are still prone to moisture.
