Roof and attic ventilation

Attic ventilation works as a pair: intake low at the soffits, exhaust high at the ridge. Get the balance wrong — or block the intake with insulation pushed into the eaves — and the roof space stops breathing. The result shows up as condensation on the underside of the decking, as shortened shingle life from trapped heat, and in colder parts of the state as ice damming, because a warm roof melts snow that then refreezes over the cold overhang. A lot of apparent leaks are actually ventilation problems.

What the job involves

  • Calculation of required intake and exhaust area for the roof
  • Inspection of soffit vents for blockage by insulation or paint
  • Assessment of ridge, gable or static vent capacity
  • Correction of mixed exhaust types that short-circuit airflow
  • Baffles at the eaves to keep the intake path clear

Signs you need it

  • Frost or water droplets on the underside of the decking
  • Ice building along the gutter line in winter
  • An attic that is markedly hotter than outside on a summer day

Questions

Can poor ventilation cause what looks like a leak?

Routinely. Condensation forming on cold decking drips onto insulation and shows up as damp patches that behave almost exactly like ingress. The tell is that it tracks cold weather rather than rain.

Is more vents always better?

No. Mixing exhaust types — ridge vents and powered fans, say — can make a fan pull air from the ridge instead of the soffits, which short-circuits the whole system. Balance between intake and exhaust matters more than total area.

Describe what you are seeing

On the coast the metal usually fails before the shingles do. Salt corrodes flashing and fasteners from the moment they go on, and the leak shows up at a junction rather than in the middle of the roof.
