Roof and attic ventilation
Airflow that stops condensation and ice dams
Valleys carry water from two roof planes into one channel, which means they handle more volume than anywhere else on the roof and fail accordingly. Debris packs into the channel, water backs up under the shingle courses on either side, and the leak shows well below where it entered. Repair means opening the courses on both sides to reach the valley metal underneath, which is more work than a surface patch — and the reason a valley leak costs more than a boot.
Mount Vernon sits close enough to the water that salt air is part of the roofing equation, and it is the part most people miss. Salt accelerates corrosion on every metal component up there — flashing, fasteners, drip edge, vent collars — so the parts of a roof that are supposed to outlast the shingles often do not. Add hurricane exposure, where Montgomery County takes both the wind and the horizontal rain that comes with it, and the older housing stock near the water with its steeper pitches, slate and tile sections and complex roof geometry, and the result is a market where leaks cluster at the junctions rather than in the open field of the roof.
Mount Vernon has a population of about 1,990, and the housing stock here sets the pattern for what fails first on a roof.
Because reaching the valley metal means lifting shingle courses on both slopes and reinstating them correctly afterwards. A patch on top of the valley does not address what is underneath and tends to fail within a season.
Yes, and it is worth doing annually anywhere with overhanging trees. Most valley failures start as a blockage that backs water up under the courses; clearing it is far cheaper than the repair it prevents.
