If the edges are curling or the granules have worn off, it is time to replace it.  

With the mass upzones of the 2040 plan, the city is trying to find ways to track/record every bit of housing data (so they can granulize all the fee's and penalties they'll use to zap multifam owners in a more efficient way).

These are but a few granules of information.

Here's the pertinent info:Apartment: 500 sq. ftFoundation: Assume no repairs neededRoof: Some surface granulation failures, will need to be repairedFull gut renovation of kitchen, living room, bedroom, and bathroom.Appreciate any and all thoughts.

After the inspection on saturday was finally completed, i recognized the need to get estimates on a new roof because of granule loss and missing asphault shingles.

However, since they just moved in, I would probably provide them with some ant traps or granules to get started.

At that time we meet with a company and have them do an annual service where all switch and outlet plates are removed and granules put in, they pull back the appliances and drop granules, treat the hinges of the kitchen cabinets and also do a perimeter spray.This really works!

Active ingrediant Fipronil is the way to go.Termidor - external spray (termites and ants)Phantom - internal spray (ants and roaches and household pests)Gel bait - internal roaches and ants (only reason to use this is if you want to spray cupboards or counters but there are dishes etc on them)granules - gets rid of fire ants on entire treated area.. awesome stuff ie.. your yardThe spray and gel work the same.

On most units like you describe, you could have Mod Bit (Modified Bitumen) with colored granules, or it could be smooth; could be the white TPO material, but if aging it needs attention. 

Then place the granules in the holes - rain will take care of the rest.
