Prepare a Tile Roof for Heavy California Rain

A tile roof should be checked for visible damage and drainage problems before prolonged winter rain. Do not assume that a tile surface is trouble-free because it looks intact from the street. Ask a qualified roofer to inspect the roof if you see broken or displaced tiles, signs of a leak, or a history of repairs.

What to look for from the ground

Look for tiles that are cracked, missing, or out of line, along with debris in valleys and around roof openings. Check inside the home for new ceiling stains or signs of moisture after rain. These clues do not prove the exact source, but they are reasons to get a closer assessment.

Avoid walking on roof tiles. A roof can be slippery or unsafe even when it appears dry, and a professional can examine the surface and areas beneath it.

Ask about the whole roof system

When a roofer assesses a tile roof, ask what was found at the roof covering, flashing, penetrations, edges, valleys, and drainage points. If repairs are recommended, ask why the proposed work addresses the issue and whether concealed conditions could change the scope.

If several areas show wear or recurring leakage, request both a repair scope and a replacement scope when appropriate. A new roof should be recommended because of the roof’s condition, not simply because El Niño is forecast.

Clear drainage before storms

The California Coastal Commission recommends inspecting roofs for wear or damage and clearing gutters and drains before severe weather (California Coastal Commission guidance). Clear accessible debris safely from the ground or hire someone equipped to work at height. Do not attempt roof work during rain or high winds.
