True Guard Roofing serves homeowners and businesses throughout San Bernardino County — from the Inland Empire cities of Ontario, Rancho Cucamonga, and Fontana to the High Desert communities of Victorville, Apple Valley, and Hesperia. San Bernardino County is the largest county by area in the contiguous United States, and we cover it all.

San Bernardino County's roofing environment is demanding: the Inland Empire experiences intense summer heat that degrades roofing materials faster than coastal areas, while the High Desert adds extreme temperature swings between day and night. The mountain communities of Big Bear and Lake Arrowhead require roofs built to handle heavy snow loads — a very different challenge from the valley floor.

We install and repair asphalt shingles, concrete and clay tile, TPO flat roofing, modified bitumen, and metal roofing across all of San Bernardino County. Every estimate is free and written — no obligation.
