The eastern Pacific hurricane season runs from May 15 to November 30, and it is most active from late August into September, which is also the wettest month here. A house that has just been through a season shows you everything you need to know.

On the roof

  • Flat roofs need a real slope and clean scuppers. Look for water stains on the ceiling under the drains and at the corners.
  • Check the waterproofing membrane: cracks, bubbles or patches tell you when it was last redone.
  • Ask when the roof was last sealed and by whom.

Around the lot

  • Arroyos are dry most of the year and run hard after a storm. See where the water crossed the land, and whether the access road was cut.
  • Look at retaining walls and the base of exterior walls for erosion or new cracks.
  • On a lot, ask the neighbours what the last storm did. They remember.

Metal, glass and salt

  • Rust stains on exposed concrete, especially on the ocean side, mean the steel inside is working. Have an engineer look at them.
  • Railings, hinges and window frames: marine-grade stainless or galvanised steel survive; plain steel shows rust after one season.
  • Large sliding doors: check the tracks and their drainage — sand and salt jam them first.

Water and power

Ask how the house managed water and electricity during the season: cistern size, pump, a generator or batteries. In a storm, these are what make a house liveable.
