Tear off, ridge vents, GAF Timberline HD shingles.

Wheat Ridge uses IRC 2006, and I assumed it was from there.

The REIA meets at Oriental Buffet (McIntosh & Bee Ridge) Wednesdays at noon, and then there are two monthly meetings, one in Bradenton, one in Sarasota for the Landlord Association - but that has a yearly due schedule to attend - however the speakers there make the $50/year well worth it.

For Rehabbing I would stick to East Nashville, Madison, Hermitage, Goodlettsville, Spring Hill, MurfreesburoAreas to avoid for rehabbing would be, Antioch, Cane Ridge, La Vernge, North Nashville, Whites Creek, Joelton, Pegram.This is based on data I pulled from the MLS and my observation.

I live in View Ridge area of Seattle where Ive owned my home since 2003.

Join the local REIA, we meet Wednesdays at the Oriental Buffet on Bee Ridge, at McIntosh, you can learn a TON from the minds that converge on that room! 

Especially area near tech ridge.

@Brandon Baker, In LR bet you would like Broadmoor, some pockets of Midtown around Markham especially, SWLR off of Stagecoach/Colonel Glenn, Yorkwood, a few great pockets down Geyer Springs, lots of pockets down Vimy Ridge, in Shannon Hills, and also Mabelvale. 

I would assume that the old system uses R-22 refrigerant, and the new will be R-410 which will be much more energy efficient.I would recommend getting a price from both Blue Ridge Heating & Air, and McGrady Perdue.

I've read quite a bit about how dangerous the southern area of Montclair is, specifically near Bloomfield Ave and Glenfield Park, by the Glen Ridge border, and that it should be avoided.
