Pipe boots and sealant
Pipe boots come first. On the Charlotte and Union County roofs we inspect, what we find most often is a boot or a sealant bead gone while the shingles still have years in them. Every plumbing vent through the roof has a rubber collar around it, and those collars split long before the shingles wear out, on most roofs we look at anyway.
Then sealant, the beads at the counter flashing and the vent caps, and the exposed nail heads on the ridge caps and the last course. Old sealant gets cut out and renewed, not smeared over.
Debris and attic ventilation
Debris collects in the valleys, the low spot behind a chimney and the gutter guards. Leaves and shingle granules both collect there, and wet debris in a valley keeps water sitting on the shingle mat. We clear it on the maintenance visit; the reviewer with the drainage problem was told the cause was most likely debris in the gutter guards.
Attic ventilation gets checked too. No ridge vent or a blocked soffit intake means a hot attic and condensation on the decking in winter, and attic venting repairs are work we do.
Planning a replacement ahead of time
Maintenance is also when a replacement gets planned ahead of time. If the shingles are losing granules across whole slopes, or the decking is soft along the eaves, we tell you that with photos.
You get a replacement estimate to keep on file, with no pressure to act on it. One Google reviewer wrote that when they had to put their project on hold our owner did not try to pressure them into doing it sooner.
Storm season and home sales
The other time it pays is storm season, because the details that leak in a heavy rain are the same boots and sealant beads the maintenance visit renewed. If you are buying or selling a home in Charlotte the maintenance inspection doubles as the roofing answer for the home inspection report, and the repair-and-seal items on that report are work we handle. After any hail or high wind the same inspection becomes the photo record your insurer would need; see Storm Damage & Insurance Claims in Charlotte for how that works.
