Wind, heat and exposed ridges
Moreno Valley is known for a gusty reputation. Wind funnels along the freeway corridors and off the surrounding hills, and fall gusts can be strong. Tiles on exposed ridges and hips are vulnerable, shingles can lift at the edges and loose flashing starts to flap.
Heat is the quieter enemy. Summer sun dries sealants and plastic vent parts, and rubber boots around pipes crack. Flat roofs on commercial buildings expand and contract all day, which strains seams. Large warehouse roofs are especially exposed, and drain clogs after a windy week can turn the first rain into a ponding problem. Looking for debris and loose pieces after every strong wind is a sound habit.
