Dry summers and wet winters concentrate water intrusion into a few months, so flashing and drainage details that hold are what matter most.
Most leaks are not the field of the roof. They are penetrations and transitions - step flashing at walls, pipe boots, valleys, chimney counterflashing. A roof can look sound and still leak at a boot that has gone brittle.
A tear-off versus an overlay is not just cost. A second layer hides the decking, so soft sheathing stays buried, and it holds heat that shortens the new shingles' life.
What the job includes
- Full tear-off and replacement
- Leak diagnosis and targeted repair
- Flashing, valley and boot replacement
- Decking repair and ventilation
- Metal and low-slope systems
- Storm damage documentation for claims
Homes in San Jose and roofing work
Public figures for the city of San Jose in Santa Clara County, not the metro, and the general practice that follows.
The median home in the city of San Jose was built in 1976, older than the U.S. median of 1980 and about the same as the California median of 1976.1 Somewhat more of San Jose's housing predates 1980 than the national share: 60% against 50%, with 9% built since 2010.1 On a roof of that vintage a contractor should check the decking before quoting - a tear-off rather than an overlay is the usual recommendation so soft sheathing is found, not buried. Annual precipitation is low, about 13 inches.2,3 Low rainfall does not mean low wear: sun and heat age shingles and sealant, so an inspection looks at granule loss and cracked boots rather than water stains.
Summer heat is moderate: about 16 days a year reach 90°F.2,3 San Jose is about 23 miles from the ocean or Gulf coast in a straight line.4,5 Near the coast, fastener grade and wind rating matter: ask for stainless or hot-dipped galvanized fasteners and for the installed wind rating of the shingle system. Owner-occupied homes in San Jose are older than rentals: a median build year of 1973 against 1979.1 Where owner-occupied homes skew older, a repair-versus-replace conversation is the usual starting point rather than a like-for-like swap.
Building permits in San Jose are normally issued by the city building department.6,7 Re-roofing permits, where required, are filed by the contractor with the city before work starts.
