What does a roof replacement involve?
A full replacement strips the old roofing down to the deck, checks the wood for damage and builds the new roof back up in layers.
- Tear off the old shingles, underlayment and worn flashing.
- Inspect the roof deck and replace any soft or rotted boards.
- Install underlayment and a water barrier at the eaves, valleys and other weak points.
- Fit new flashing around chimneys, vents, skylights and walls.
- Install the new roofing material, then the ridge cap and ventilation.
- Clean up the yard and sweep it with a magnet for stray nails.
Details vary by roof and material, so ask for the scope in writing. Ventilation matters a great deal in an Austin attic, where summer heat builds up fast and cooks the roof from underneath. A good plan covers intake and exhaust, not just the shingles on top.
