Why riverside roofs need a closer look
Air along the river holds more humidity year-round, and that moisture clings to north-facing slopes, settles into shaded valleys, and feeds the moss and algae that slowly pry shingles apart. Add the freeze-thaw swing that comes with sitting right on the WA/ID border with Newport, and you have water expanding inside hairline cracks every cold night.
Our inspection is built around that reality. We look for the slow, hidden damage riverside humidity causes - not just obvious storm hits - so small problems get caught while they are still cheap to fix.
What we check on every inspection
A DG Contracting roof inspection covers the full system from the deck up:
- Shingles and field: lifting, cracking, granule loss, and moss colonies along shaded edges
- Flashing and penetrations: chimneys, vents, and skylights where river-fed moisture tends to concentrate
- Valleys and low slopes: the spots that stay wet longest after rain or snowmelt
- Attic and decking: staining, soft sheathing, and signs of trapped humidity
- Gutters and drainage: whether water is actually leaving the roof or backing up against it
You get a plain-language report with photos, not a sales pitch.
Ice dams and snow load on the Idaho side
Winters near Oldtown bring real snow, and the freeze-thaw cycle along the Pend Oreille River makes ice dams a recurring threat. Meltwater refreezes at the cold eaves, then forces itself up under the shingles where it can rot decking and stain the rooms below.
We check insulation balance, ventilation, and eave protection so your roof sheds snow the way it should instead of holding a frozen ridge of water along the gutter line all winter.
When an inspection makes the most sense
Schedule one after a wind or hail event, when buying or selling a home, or any time you spot a stain that wasn't there last season. River-adjacent homes especially benefit from a look every couple of years even with no obvious symptoms, because humidity damage builds gradually rather than all at once.
If the inspection turns up work worth doing, we explain your options clearly. Our roof replacement projects include a 15-25 year workmanship warranty and are backed by a 15-25 year workmanship warranty plus the GAF Golden Pledge.
