I know that I'm supposed to wait 1 week after removing existing grass, weeds, debris before laying sod. My question is: How important is that 1 week timeline? What if I wait 2 or 3 weeks? What if I wait less than 7 days?
Seriously, I have never heard of waiting a time period before laying sod. Except maybe if a herbicide was used that might effect the root development of the sod. But even at that, I have sprayed glyphosate (41%) over the soil just for insurance and waited maybe two days, but that was more of a scheduling thing of waiting for the sod delivery or maybe waiting a day or so for a rain front to come in and try to lay the sod just before.
If it's worth doing, it's worth doing right. If you wouldn't put your name on it, it ain't done right!
