What does a roof replacement involve?
A full replacement means taking the old roofing down to the deck, not laying a second layer on top. In most cases the steps run like this:
- Protect landscaping, windows and the driveway, then strip the old shingles and underlayment.
- Inspect the roof deck and replace any soft or damaged boards.
- Install ice and water barrier along the eaves and in valleys, then underlayment over the rest of the deck.
- Fit new flashing around chimneys, skylights, vents and walls.
- Install the new roofing, ridge cap and ventilation.
- Clean up, sweep the yard for nails and check the gutters.
Colorado codes and local building departments can call for specific details, such as underlayment type, ventilation and fastening. Your quote should say which materials and brands are included, in writing.
