To answer your questions correctly if a runway is “overhauled”, repaired, other major work performed the compass rose has to be re-certified. Below is some guidance material.
Compass swing procedures for non-electrical compass systems (systems that require no electrical power to operate and/or indicate) are in Advisory Circular 43.13-1B, Change 1, and 150/5300-13, Appendix 4, paragraph 3.
CAUTION not all compass roses are legal to use just because they are painted on the ground there is more to it than tha.
For pavement construction, the applicable portions of AC 150/5320-6 should be used. The following additional information is important:
a. Do not use magnetic materials, such as reinforcing steel or ferrous aggregate, in the construction of the calibration pad or of any pavement within a 300-foot (90 m) radius of the center of the site. If a drainage pipe is required within 300 feet (90 m) of the center of the site, use a nonmetallic or aluminum culvert.
b. Each of the radials is oriented within one minute of the magnetic bearing indicated by its markings.
c. Mark the date of observation and any annual change in direction of magnetic north durably and legibly on the surface of the calibration pad near the magnetic north mark. It would be well to establish a permanent monument at some remote location on the true north radial for future reference.
d. The U.S. Geological Survey of the Department of Interior is available to conduct the necessary surveys to determine the difference between true and magnetic north and the uniformity of this difference. The cost for this service is that necessary to cover the expense to the U.S. Geological Survey. Request for this service should be made to the following:

There are also many other competent registered surveyors or engineers who are capable of performing these surveys. It is recommended that a qualified engineer be employed to lay out the work in the field and to design the pavement for the critical aircraft that can reasonably be expected to use the pad.
e. After all construction work on the compass pad is completed, it is advisable to have the pad magnetically resurveyed to guard against the possibility of objectionable magnetic materials being introduced during the construction.
f. Magnetic surveys of existing compass calibration pads should be performed at regular intervals of 5 years or less. Additional surveys should be performed after major construction of utility lines, buildings, or any other structures within 600 feet (180 m) of the center of the pad.
7. VOR CHECKPOINT.
At some airports, it may be advantageous to collocate a VOR checkpoint with the compass calibration pad. In such instances, the requirements presented in paragraph 201.3212 of FAA Handbook OA P 8200.1, United States Standard Flight Inspection Manual, should be followed.
