Heat Ready Exteriors in La Habra Heights

For an inland suburb like La Habra Heights we lean on metal vents, flashing and screens, then size attic vents so ember mesh still lets the heat escape.

We plan La Habra Heights work by its general category, an inland suburban part of the San Gabriel Valley. As a broad rule, an inland house is worked harder by heat than by damp, so our choices lean toward metal and mineral products that tolerate sun. Heat also makes attic ventilation a design question the moment ember screening goes in, and we answer that question on paper before a single vent is ordered.

Metal where it lasts

With little damp air to drive corrosion, galvanized steel and aluminum hold up well on an inland exterior, so we specify metal for gable and foundation vents, window head flashing, drip edges and weep screeds. Metal does not burn either, which counts at every opening an ember could reach. Walls get cement plaster or fiber cement, both noncombustible and both stable under strong sun, finished with a mineral coat in a light color that reflects heat. Joints take a high movement sealant, because a wall that warms and cools each day works its joints hard.

Venting with ember mesh

Fine ember mesh stops sparks, and it also slows air. A screen with openings near 1/8 inch passes noticeably less air than the coarse louver it replaces, so swapping vents one for one can leave an attic short of the net free area the code sets for ventilation. We count the existing vents, read the net free area printed on each replacement, and add eave or ridge openings where the total comes up short. A cooler attic is easier on the roof deck and on the rooms below it, and the ember screening stays whole.
