The home is in good condition overall. The exterior of the house is well sealed and painted and the drainage is good. All systems, to the extent that they could be inspected, were in working order at the time of the inspection.
The roof is the only system in question. There are several locations were nails were not correctly installed and were patched; the patch material is cracking. Several other locations were noted where shingles were damaged. The roofing underlayment was not applied correctly to the eve drip edge and was cut too short to go over the drip edge flashing. One location was noted where there was no kickout flashing to help prevent water from entering where a horizontal and vertical edge meets.
As we discussed, some shingle manufacturers do not warranty their shingles if water from one surface is discharged directly onto another roof surface. I recommend that you determine the make and model of the shingles on your home and check with the manufacturer. If the manufacturer does not allow water to discharge this way then the drainage system will need to be modified.
Infrared thermography of the structure at the time of the inspection did not reveal any locations where moisture levels were elevated. Conditions were good for finding leaks since it had rained earlier in the morning, but none were detected. The attic was accessed and no moisture intrusion was found. There is one location where moisture intrusion may be possible on the west side of the house at the bottom of the shingle valley. Additional flashing/protection of this area is necessary to ensure against moisture intrusion.
No carbon monoxide detectors were noted, however, the smoke detectors also are carbon monoxide detectors. There is no need for additional detectors.
