Insulation in San Jose: what to know
Eichlers with flat or low-slope roofs often have little to no insulation above the ceiling, making summer heat and winter chill hard to control. Rigid foam added during a roof replacement is a common fix, while traditional ranch homes in Almaden Valley and Cambrian Park benefit from blown-in attic insulation and air sealing. Late spring is ideal before hot spells, and work tied to reroofing often needs a permit from the city.
