Country clubs, large custom homes and the foothills of the Santa Rosa Mountains, in a city the county places inside a special wind region.

Conditions
Riverside County Building & Safety names Rancho Mirage in the special wind region list in its July 2021 handout, which gives 130 mph for Risk Categories I and II at Exposure C. Major A. Ronald Button, who bought land here in 1944, called it the most wind-free area he could find in the desert; the county’s design list says otherwise. Confirm current site criteria before specifying tile fastening and edge details.
Rancho Mirage was formed from cove communities at the foot of the mountains, and a 1979 flood on the Magnesia Spring Creek fan caused a death and about $7 million in damage before concrete spillways were built. For a single house, the question is whether gutters, downspouts and roof valleys carry a cloudburst away from the walls. Check those routes together.
Summer highs above 108 °F are common and can pass 120 °F, while annual rain averages under 5 inches. The permanent population is about 17,000, but the seasonal population can exceed 20,000, so many homes stand empty through the hottest months. Arrange inspection access with whoever looks after the property so a slipped tile or failed seal is found before the next storm.
The roofs here
Thunderbird Country Club opened in 1950 and Tamarisk followed in the same decade, then Sunrise, The Springs, Mission Hills and Morningside between 1974 and 1982. Homes in those clubs span several decades of roof systems, and many have been re-roofed at least once. Establish what the current assembly is, and what each earlier repair changed, before deciding whether to repair or replace.
Much of Rancho Mirage’s housing sits inside gated clubs with their own architectural rules. Tile profile, color, ridge detail and even working hours may need the club’s approval as well as a city permit. Confirm those requirements before ordering material, so the written scope matches what the association will accept and the schedule allows for its review.
Custom homes in the city often have long hips, multiple valleys, towers and roof-mounted equipment. Each junction is a place where tile, underlayment and flashing have to work together, and where water finds its way in first. An inspection should lift tiles at valleys, walls and penetrations instead of judging the roof from the open field.
Local building patterns help guide an inspection. Your roof’s actual condition, materials and repair history determine the recommendation.
Code and permits
Confirm the requirements for the building and proposed roof assembly. The links below go directly to the relevant authorities.
92270 falls in California building climate zone 15. Climate zone, building type and roof slope help determine the energy requirements for a proposed roof. California’s climate-zone rules do not apply to our Arizona service region.
The CEC's climate zone listCalifornia’s 2025 Energy Code took effect January 1, 2026. Cool-roof requirements vary by building type, climate zone, roof slope and project scope. Check the applicable path and the product’s CRRC rating before choosing a roof surface.
A single reflectance or SRI threshold does not apply to every roof. Confirm the current requirements and any exceptions with the building department.
Title 24 at the Cool Roof Rating CouncilRiverside County Building & Safety names Rancho Mirage among the communities lying inside an ASCE 7 special wind region in its July 2021 handout. That document puts the gust there at 130 mph for Risk Category II, Exposure C, against 100 mph in the parts of the county that are not. Wind load rises with the square of the speed, so that is about 69 per cent more load — carried by the fastenings, the perimeter and the edge metal.

What we do
Large tile roofs need their valleys, walls and underlayment checked, and club rules shape the visible choices. Compare repair, re-laying and replacement from the inspection.
