What moves a South Bay bid?

  • Tile: often redone by lifting tiles to replace worn underlayment, then relaying them, a different job from a tear-off (tile guide).
  • Eichler and flat roofs: membranes, insulation choices and drainage (flat roofs).
  • Cool-roof product: required for most reroofs here; compare qualifying products, not just the cheapest shingle.
  • Solar: remove and reinstall (solar and a new roof).
  • Two-story tracts: more staging and safety setup.

Do tile roofs always cost more?

Relaying existing tile over new underlayment is a different scope than a shingle tear-off; get it priced specifically.

Are cool-roof shingles more expensive?

Prices vary by product line and color. Most reroofs here need a rated product anyway.

Can you price my roof from the form?

No. The form gets a licensed roofer to measure and inspect; their written estimate is free.
