Swamp coolers may be affective enough, just remember they are pumping even more moisture into the house on top of the natural humidity.

If there is no ventilation, adding a vent that turns on with the light could be a huge help in limiting moisture levels in a bathroom, if nothing else it will pull fresh air into the bathroom and help get rid of any odors.  

Laminate is made from MDF which does not do well when exposed to moisture. 

I actually have a camera also, but a good camera is a bit pricey. in Utah, and other areas they used lead to seal the pipes and trees like to penetrate the lead and create havoc.

A good inspector will have a moisture detector and can point out any water trapped in behind walls, which could indicate potential mold or rot issues.  

A fiberglass system costs more, but provides more durability over the long term and reduces the chances of a negligent tenant not making a water penetration issue notice to management.  

3 plex flat roof property has leaks on the inside, had a few roofers looked at it.the scope of work involves:1.Existing roof has many years of patching and patching and needs replacement, considering a tapered insulation system to give a bit of slope for rain runoff.2.Many of the joists are rotted on their ends due to moisture damages and neglect, so a significant number of those need to be repaired by sistering a longer piece to tie it back tobwhere the members are solid.3.Some plywood decks if rotted may need replacement, no telling now many until roofing membranes are torn off.4.All wood fascia are to be replaced due to rot.5.Repaint new fascia.Am I correct that I should request two invoices two "jobs", item 1 is new roof to be depreciated, item 2-5 are repairs that may be expended one time?

Their personal space requirements are much larger but you can have a powerful impact if you learn how to penetrate their barrier(s). 

I don't like the idea of moisture down there at all, but I don't want to overspend under the house when the gutter situation may resolve it.

The sprayed loose foam packs down over time and becomes massively less effective; especially if it comes in contact with moisture.
