Cleaning Verification

If a renovator uses the required practices to remove containment and clean a work area, then performs successful cleaning verification, can the balance of the project then be done using uncertified workers and without reference to the work practices required by the RRP Rule?
My firm is replacing windows on the second floor of a 90 year old home. The windows are built into a bay that projects out from a steeply pitched slate roof. When setting up exterior containment for this job, does the RRP Rule require me to install plastic on the roof under the windows?
Typically, interior clearance is achieved by means of dust wipe sampling by a certified inspector or risk assessor using single surface dust wipes. This is required on all HUD jobs. EPA rules at 40 CFR 745.227(e)(8)(ii) allow for composite sampling in clearance testing. Under the RRP Rule, is composite sampling acceptable for clearance in lieu of cleaning verification?
