Different buildings need different crews, so this is the first thing a roofer asks.

What moves the price

  • 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
  • Warranty tier, which is really a question about who honours it in fifteen years
  • Pitch — anything over about 7:12 needs staging and slows a crew down
  • Ventilation work, if the old roof was cooking itself from underneath

Locally

It is why two identical houses on the same street can be ten years apart on the same roof, depending on which way they face.

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.

Questions about price

How long does a re-roof take?

Two days is typical for asphalt. Add days for steep pitch, multiple layers to strip, tile work, or a roof with a lot of valleys and penetrations.

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 moss on the roof a problem?

It matters more than it looks. The damage is not the moss, it is the permanent damp underneath it. Kill it and brush it off gently; never pressure wash asphalt.
