🌡️ It Is 98 Degrees in Orange County — And Rain Is Coming This Weekend
If you checked the forecast this week, you already know. Temperatures across Orange County are pushing close to 100 degrees today, and by Sunday there is a real chance of rain. That combination is not just uncomfortable. It is one of the worst things that can happen to a roof that is not in good shape.
At Fox Roofing Company, we call this Santa Ana season. Hot, dry, inland winds push temperatures up, pull moisture out of every roofing material on the surface, and then rain arrives before anything has had a chance to settle. For a roof with any existing weaknesses, that sequence accelerates damage faster than most homeowners expect.
What This Week's Heat Is Doing to Your Roof Right Now
1. Sealants Are Drying and Cracking
At near-100 degree temperatures, the sealants around chimneys, skylights, pipe vents, and wall flashings are under serious stress. Materials that were marginal heading into fall are cracking open right now. When Sunday's rain arrives, those gaps are entry points.
2. Tiles Are Expanding Under Extreme Heat
Concrete and clay tiles absorb and hold significant heat. The thermal stress from temperatures swinging nearly 30 degrees between daytime highs and overnight lows puts pressure on mortar at ridges and hips. Tiles that were already slightly out of position can shift further this week.
3. Underlayment Is Being Pushed Past Its Limit
Extreme heat is one of the final stressors on aging underlayment. On tile roofs throughout Irvine, Mission Viejo, Newport Beach, and across Orange County, underlayment that has been quietly deteriorating can reach the point of failure during a week like this one.
Why the Rain on Sunday Changes Everything
Dry heat and rain back to back is one of the most revealing combinations a roof can face. Roofing materials contract when temperature drops. Sealants that cracked in the heat cannot seal back up on their own. Water finds those gaps immediately.
If your roof has any unresolved issues from earlier this year, this weekend is when they show up inside your home.
What to Do Before Sunday
If you have noticed anything on your roof this summer, a cracked tile, a small stain on the ceiling, flashing that looked like it was separating, this week is the time to make the call. Not after the rain. Before it.
