Check your attic ventilation
Bad attic ventilation cooks your shingles from underneath and drives up your cooling bill.
What you'll learn
- Why a 150°F attic shortens shingle life by years
- What proper intake and exhaust flow looks like
- The #1 most common vent problem (soffits blocked by insulation)
- When moisture staining on sheathing means act now
Step by step
- On a warm afternoon, pop the attic hatch. Should feel warm, not blistering.
- Look for soffit vents under the eaves — they should be clear, not painted shut.
- Look for an exhaust path — ridge vent, gable vents, or powered attic fan.
- Check for moisture signs — dark staining, rust on nails, mold.
- Check insulation is not blocking soffit vents.
Safety note
Soffit vents blocked by insulation are the single most common ventilation issue. Fixing it is often a 1-hour job. It protects your entire roof investment.
