Attic Insulation & Air Sealing

An attic that leaks air or has thin, settled insulation makes a home work harder to stay cool in the summer and can leave moisture sitting where it shouldn't. SmithBuilt Roofing and Exteriors looks at insulation and air sealing as part of the roof assembly, not a separate system, since gaps at penetrations, soffits, and the attic floor affect how the roof deck itself holds up over time.

What We Look At

Air Leaks — Gaps around penetrations, top plates, and attic access points that let conditioned air escape and outside air in.
Insulation Coverage — Thin, compressed, or missing insulation that no longer performs the way it should.
Moisture Signs — Damp decking, rafters, or insulation that point to a leak or condensation issue rather than normal wear.
Ventilation Balance — Whether intake and exhaust venting are working together or fighting each other.

How We Check It

Handheld infrared cameras trace temperature differences across the attic floor and roof deck, which helps locate where air is moving or where insulation has gone thin. Wood moisture meters give us a direct reading on decking and rafters, so any repair recommendation is based on actual moisture content rather than a guess.
