Surface temperatures run far above the air reading, day after day, for months. As a rule, debris in Mission District valleys holds what little moisture arrives against the covering, which is where rot usually starts. As a rule, roof coverings in Mission District bake.

Thermal cycling does the damage in Mission District — hot afternoons, cool nights, and materials expanding and contracting against their fixings all year. Expansion and contraction loosens fixings on Mission District roof coverings long before the material itself gives out. It is the same story on most Mission District streets. Attic ventilation on a Mission District property is not optional — trapped heat cooks the covering from underneath. That is as true in Mission District as anywhere in San Francisco County.
9The Mission District Maintenance Year
Skylight seals on Mission District roof coverings want checking annually, as they give out quietly and drip into the ceiling cavity. Walking a Mission District tile roof damages it; inspection should be from the edge, a ladder or a drone. It is the same story on most Mission District streets. Realistically, trimming back branches over a Mission District roof removes the debris that holds moisture against the covering and shortens its life. Flashings at the chimney on an older Mission District house usually call for attention well ahead of the covering does. Most Mission District roof coverings that give out early give out at a penetration someone could have resealed for a few hundred dollars. Keeping a dated maintenance file on a Mission District property pays for itself the first time a claim is questioned.
Policies covering Mission District properties generally pay for sudden damage and not for age, so the report has to separate the two clearly. Actual cash value and replacement cost behave very differently on an older Mission District roof covering, and the policy wording decides which applies. Realistically, emergency tarping on a Mission District roof is normally covered, and receipts should be kept for it.
