Roof replacement begins with an inspection and photos, followed by a written scope and price.
One call to (855) 512-1072 reaches Roofers Hotline for roof replacement in San Jose and 5 towns across Santa Clara, San Mateo and Santa Cruz counties. Calls are answered 24 hours a day and every estimate is put in writing before work starts.
With 61% of homes inside the city limits built before 1980 by Census estimates, a repair estimate often comes with a replacement estimate.
With 61% of local homes built before 1980, by Census estimates for 2019 to 2023, many roofs already carry more than one covering. The tear-off takes everything down to the deck, and the old material is hauled away. Ask for the layer count in your written estimate.
The metro averages 16.1 inches of precipitation a year in the 1991 to 2020 climate normals, and a slow leak in a roof built around the 1975 median can soften the boards below. Once the old layers are off, the deck is checked and soft sections are replaced. Call to book that inspection.
The metro gets about 2 freeze days a year and no measurable snow, so the ice-dam risk is Low. The layers under the new roof still matter, because federal disaster declarations here have included severe winter storms and flooding. Ask which underlayment and drip edge go on your roof.
Hail here is rare, with no hail events of one inch or larger in NOAA's county records since 2015, so you can choose a covering for looks, weight and heat. The metro logs about 21 days a year at 90 degrees or higher. Call to compare shingle, metal and tile in your estimate.
How the job runs, call by call, is explained under how roof replacement works.
Hail is not what sends San Jose roofs to replacement. Santa Clara County logged no hail events of 1 inch or larger in NOAA's Storm Events record since 2015, and only 2 damaging thunderstorm wind events. The largest hail in that record was 0.75 inches. What wears roofs out here is age and rain, which is why replacement is usually a question of the existing covering reaching the end of its life. Roofers Hotline handles roof replacement here: tear-off of the old layers and disposal, decking inspection, new underlayment and drip edge, and new shingles, metal or tile.
San Jose's housing stock is old. The median home was built in 1975, and 61% of homes were built before 1980 (ACS 2019-2023), which means many roofs are on at least a second covering. Annual rainfall is 16.1 inches and the 1991-2020 normals at the local station show only 2.2 freeze days a year and no snow, so ice damming is not the issue. Sun is: the station averages 21 days a year with highs of 90 F or more. Older decking under years of heat and rain is worth inspecting during tear-off.

In San Jose, watch for shingles past 20 to 25 years with widespread granule loss, since decades of sun exposure and a housing stock with a median build year of 1975 make that common. Repairs every season on different sections point to a roof failing across the board, not in one spot. Sagging deck lines visible from the street can follow years of moisture in older decking. Multiple layers already on the roof are also a sign, and they are more likely on homes built before 1980.

Why call
Because San Jose gets only 2.2 freeze days a year and no snow in the 1991-2020 normals, a replacement is not tied to a winter cutoff. Rain is the timing factor: the most recent federal declaration for the county, Severe Winter Storms, Straight-Line Winds, Flooding, Landslides, And Mudslides on April 3, 2023, was one of 15 from 1977 to date. If your roof is past 20 to 25 years or needs repairs every season, call before the wet months so the old covering is not exposed during tear-off. Calls are answered 24/7.

Questions
Rarely. NOAA's Storm Events record for Santa Clara County since 2015 shows no hail of 1 inch or larger, and the largest hail recorded was 0.75 inches. Replacement here is usually driven by age, sun and rain, not hail.
The housing stock is older. The median home was built in 1975, and 61% of homes predate 1980 (ACS 2019-2023), compared with 60% across the county. Many of those homes are on at least their second roof covering.
Roof replacement includes tear-off of the old layers and disposal, decking inspection and replacement where soft, ice-and-water shield, underlayment and drip edge, and new shingles, metal or tile with manufacturer-rated fasteners. You get a written estimate before any work starts.
California requires roofing contractors to hold a CSLB license, usually the C-39 Roofing classification. Look up any license at CSLB before you agree to work. Deductibles are never waived or rebated, so be wary of any offer that says otherwise.
A common question across the metro is How long does a roof last?
Our local guide to the roof problems seen most here draws on the same county storm and housing records. The same county storm and housing records feed our local guide to when a roof problem cannot wait.
