Roof replacement begins with an inspection and photos, followed by a written scope and price.
For roof replacement in Riverside and 5 towns across San Bernardino County, Roofers Hotline takes one call at (855) 512-1072. The line is answered around the clock, and you get a written estimate before work starts.
Census figures put 56% of homes inside the city limits before 1980, so a replacement estimate is written beside most repair estimates.
Replacement starts by stripping the roof down to the deck and hauling the old material away. About 56% of local homes were built before 1980, by Census estimates for 2019 to 2023, so extra layers under the top one are a real possibility. Call to book a roof inspection and get a written estimate that covers tear-off and disposal.
Once the old roofing is off, the deck underneath gets checked board by board, and soft or damaged sections are replaced before anything new goes on. The metro's median home was built in 1976, so decking has had decades of heat to wear it down. Ask for the decking line on your written estimate before work starts.
Underlayment and drip edge go down over the clean deck to keep water out at the edges and seams. The metro averages about 10 inches of precipitation a year in the 1991 to 2020 climate normals, so rain is occasional, but a leak in a dry climate often goes unseen for months. Call to confirm which layers your roof gets.
You choose the finish material, and it is fastened with manufacturer-rated fasteners so it holds up in wind. NOAA's storm records show 4 damaging thunderstorm wind events in the county since 2015, so fastening matters here. Call to compare shingle, metal and tile options in one written estimate.
Step by step, from the first call to the written estimate, the work is explained under how roof replacement works.
More than half of Riverside's homes, 56% by the ACS 2019-2023 estimates, were built before 1980, and the median home dates to 1976. Roofs on houses that age have often been replaced once already, sometimes with the old layers left underneath. Roof replacement here starts with a tear-off of the old layers and disposal, then a check of the decking, with soft sections replaced. New underlayment and drip edge go down before shingles, metal or tile are fastened to the manufacturer's rating. Call for a written estimate before any work starts.
Riverside's housing is older than the rest of the county. The median home here was built in 1976 against 1990 county-wide, and 56% of homes predate 1980 compared with 30% across the county. Older houses are more likely to carry several roof layers and decking that has aged under the sun. The climate adds to it: the metro Fire Station 3 normals for 1991-2020 show 110 days a year at 90 F or higher, with only 10 inches of precipitation. Heat, not hail or snow, does most of the wearing.

With 110 days a year at 90 F or higher, the signs to watch for are widespread granule loss on shingles past 20 to 25 years and repairs needed every season on different sections. Sun exposure wears a roof evenly, so trouble tends to show up across the whole surface rather than in one patch. Also look for multiple layers already on the roof, which is more likely on homes built before 1980, and for sagging deck lines visible from the street.

Why call
Storm risk here is modest. The county record since 2015 shows 4 hail events, 4 damaging wind events and 6 tornadoes, and hail peaks in April. FEMA lists 25 disaster declarations including the county from 1965 to date, the latest being Tropical Storm Hilary on November 21, 2023. Because the freeze risk is low, with 2 freeze days a year, replacement can be scheduled around the weather. Call when repairs keep recurring or after a storm leaves visible damage.

Questions
The metro's median home was built in 1976, and 56% of homes predate 1980. Many have had a roof replaced already, and some still carry old layers. Add 110 days a year at 90 F or higher, and shingles can wear out and decking can age before the house itself does.
It includes tear-off of the old layers and disposal, and an inspection of the decking with soft sections replaced. Ice-and-water shield, underlayment and drip edge go on next, followed by new shingles, metal or tile with manufacturer-rated fasteners. You get a written estimate before any work starts.
Some, but not much. The county record since 2015 shows 4 hail events, with the largest hail at 1 inch, plus 4 damaging wind events and 6 tornadoes. Tropical Storm Hilary was the latest federal declaration, on November 21, 2023. Sun and age are the bigger factors.
