Madera County.

Madera County transitions from flat valley agriculture in the west to Sierra foothill terrain in the east. The city of Madera sits at 272 feet elevation in the heart of the San Joaquin Valley, sharing the same extreme heat and agricultural dust conditions as neighboring Fresno County. But the county's eastern reaches climb toward Yosemite, bringing mountain weather patterns into play.

Wine grape and almond production dominate Madera County agriculture, and both industries generate seasonal dust during harvest. The county's position between the valley floor and the Sierra Nevada also makes it a corridor for wildfire smoke, which deposits acidic particulates on rooftops during fire season. These deposits accelerate the breakdown of asphalt shingle compounds.

Many Madera County homes were built during the agricultural boom of the 1960s and 1970s, with original roofing materials well past their rated life. A reroof here typically involves a full tear-off to inspect the decking, since decades of heat cycling often warps the original plywood. We install cool-rated materials and balanced ventilation on every Madera County project, accounting for the valley heat that defines this region.
