What best describes your home?

What moves the price

  • Permit and inspection fees, which vary more between towns than people expect
  • Ventilation work, if the old roof was cooking itself from underneath
  • Access — a truck that cannot get near the house adds hours to every load
  • Where you land in the season; crews discount when the phone is quiet
  • How many old layers have to come off before the new one goes on

Locally

The south and west slopes fail first and fail visibly. Everything else follows some years later.

Ask where the water goes and what happens when the drain blocks. On a flat roof that is not a detail, it is the design.

These are estimates, not quotes. They are compiled from national installed ranges adjusted for California costs and for how Perris is built. No contractor is bound by them.

Questions about price

Can I just put a new roof over the old one?

Often you legally can, and it is usually a poor idea. Overlaying hides the condition of the decking, adds weight, shortens the life of the new shingles by trapping heat, and doubles the cost of the next tear-off.

Is this really free?

It is free to you. Contractors pay to receive homeowner requests in their area. That is the entire business model, and we would rather say so plainly than pretend otherwise.

Can I stay in the house while it is done?

Yes, though it is loud, and things will fall off shelves in the garage. Move cars out of the driveway and take anything fragile off the walls of the top floor.

It is free, and nothing obliges you to hire anyone.
