In nearly all of the continental US,
1) roundup will kill everything
2) seed will not germinate in November
3) in December you'll have frozen dirt and no grass.
+1......
Crab grass is an annual. Absolutely no reason to kill when next years crop comes seed.
Aerate, seed then cover with straw in the fall. Mid- September into early October works well in our area. Or..... my preferred method, wait until late February, early March and let the freeze, thaw cycle work the seed into the ground. Then use a fertilizer with a crab grass preventive in the Spring.
