First Freeze in the Brazos Valley Lands 27 to 29 November. What to Check Before It Does

The first light freeze of the season typically arrives in the Brazos Valley between 27 and 29 November. That leaves most homeowners in Bryan, College Station and the surrounding towns about three months of comfortable working weather to deal with anything on the roof that a freeze would make worse.

Here is the short version. Before the end of November, check five things: that the gutters and downspouts run clear, that the flashing around every penetration is sound, that no shingle or panel is lifted or missing, that the attic is dry and ventilating, and that exposed sealant has not cracked. None of that requires you to get on the roof. Most of it is visible from the ground with a phone camera, or from inside the attic with a flashlight.

The reason to do it before the freeze rather than after is straightforward. Water that sits in a blocked gutter or behind failed flashing expands when it freezes. A hairline separation becomes an opening. An opening that goes through a winter becomes a stain on a ceiling in February.

Why this particular winter is worth moving up the calendar for

On 13 August 2026 the NOAA Climate Prediction Center issued an El Nino Advisory, citing a greater than 90 percent chance of a very strong event during the Northern Hemisphere fall and winter of 2026 to 2027, and a 69 percent chance that the event reaches historic strength during October through December.

What that tends to mean here is more moisture. NOAA's drought monitoring describes a typical El Nino winter as one in which an extended Pacific jet stream brings wetter and colder conditions to the southern tier of the United States.

The qualifier is NOAA's own and it matters: El Nino "usually (but not always)" coincides with cooler, wetter conditions in the southern United States, and the historical record in Texas is genuinely mixed. Some El Nino winters have broken droughts here. Others barely registered.

So this is not a forecast about your roof. It is a reason to do the walk in September or October instead of letting it slide to December, because a wetter winter puts more water through every joint in the building, and the joints are where roofs fail.

The five checks

1. Gutters and downspouts

Look for standing water, sagging sections, and granules piled at the downspout outlet. A gutter that holds water in November holds ice in January, and the weight pulls the fascia away from the house. Granule buildup is worth noting but is not by itself alarming on a roof that was installed recently.

2. Flashing at every penetration

Every place something comes through the roof is a place water can get in: chimney, plumbing stacks, exhaust vents, skylights, and the valleys where two planes meet. From the ground with a zoom lens, look for lifted metal, gaps, or sealant that has pulled back from the edge.

3. Lifted, cracked or missing material

On shingle roofs, look for tabs standing proud of the course below, corners curling upward, and bare spots. On metal, look for backed out fasteners and any panel that has moved at the seam. Photograph anything you find, with something in frame for scale.

4. The attic

This is the check most people skip and the one that tells you the most. On a dry day, go up with a flashlight and look at the underside of the deck. Dark staining, rusted nail shanks, damp insulation and any daylight you can see through are all worth a call. While you are there, confirm that the soffit vents are not packed with insulation, because a roof that cannot breathe in winter sweats from the inside.

5. Sealant

Exposed sealant is a maintenance item, not a permanent one. Where it has cracked, shrunk or lost adhesion, it stops doing its job before it looks dramatic.

If you find something

Photograph it, note where it is, and get it looked at while the weather still allows unhurried work. Anything found in September gets handled on a normal schedule. The same thing found in January gets handled around rain and cold, and the interior damage has had two months to develop.
