I'm from Houston which is a much larger city that has 3 perimeters now. 

They come out and treat the ground before you pour your slab and then they come back in one year to treat the perimeter.

I'll most likely target areas south of the Perimeter as I'm most familiar with that part of town.  

I'm considering using landscape style uplighting around the perimeter, or, since the roof is being re-decked anyway, having some soffit lights installed. 

This is standard architectural shingles, ice and water up 3' to code, felt, shingles, ridge vent, drop edge all around, new boots, flashing at chimneys and walls, no soffit work.To get close on roof SQ find he perimeter of the house dimensions and get the SF of that (not just house SF as two stories, added garages etc all factor in). 100SF is a Sq and that's how roofing is usually priced.

You may find that the perimeter of the foundation is fine but stop gaps (like the cinder block and jacks) were used to prop-up sagging floors - and that an immediate corrective action is not needed. 

Also—a hump in the middle if the room is usually one of two things:-the floor was saggy and owners jacked up the middle but overcompensated-the exterior walls have settled deeper than the middle because the exterior perimeter soil is wetter over the years due to rainfall off the eaves

Contact Mike O'Conner at Perimeter Property Management.You can also go to www.narpm.org to search their directory of managers.

I've had the same problem with a couple of wood laminate floors that were not installed with expansion room around the perimeter. 

I live on the north-end of Atlanta but do most of my investing inside the city-perimeter.
