Most homeowners don’t know the state of their attic until someone actually goes up there and looks. We do that on every job.
Common Questions About Insulation & Air Sealing
Why do you check the attic during roofing jobs?
Because the attic is where roofing problems often start and where you lose the most energy. Improper ventilation causes ice dams in winter and accelerates shingle aging. Catching it during a roof job costs far less than finding it later.
What R-value does my attic need?
For Maryland, the current code recommends R-49 to R-60 in attics. Many older homes in Frederick County fall well short of that. We'll measure what you have and tell you exactly what the gap is.
What's air sealing and why does it matter more than insulation?
Air sealing plugs the gaps where conditioned air escapes: around wiring, pipes, top plates. Insulation slows heat transfer; air sealing stops air movement. They work together, but most contractors skip the sealing step.
Can you combine an attic insulation job with a roof replacement?
Absolutely. This is actually the ideal time to do it. Deck access makes air sealing easier, and we're already up there. We'll scope both in a single estimate.
