We live a few streets from Oak Forest Elementary, the school on Kingwood Glen in Humble. Humble ISD opened it in 1995, and many nearby homes date from the 1990s and early 2000s. Every school morning, I watch kids stream past our driveway. Last summer, I noticed something else. Our upstairs rooms felt like an oven by 3 p.m.
At first, I blamed the AC. It ran all day and never caught up. Then a friend asked me a simple question. When did I last look in my attic?
I had no good answer.
What I Found Up There
I climbed the ladder on a Saturday morning. It was already sticky and hot up there. The insulation looked fine at first. But near the eaves, it was packed tight against the roof deck. I could not see any light coming through the soffit vents.
I also found a few dry, dark spots on the wood near the ridge.
Our house is not new. Plenty of homes around the school have roofs that have seen a lot of Texas summers. If your attic has never been checked, it may be hiding the same problem.
Our power bill had crept up every summer, too. Poor attic ventilation in Humble homes is easy to miss when you never go up there.
Getting a Second Opinion
I wanted someone who would explain things, not just sell me a roof. My husband wanted a GAF-certified installer, since our shingles are GAF. A coworker suggested STX Roofing. They are a veteran-owned, GAF Master Elite company out of Huffman, and the owner used to work as an insurance adjuster. That mix sounded right for us.
Their inspector spent most of his time in the attic, not on the roof. He pointed out that insulation was blocking our soffit vents. Hot air had nowhere to go. It was cooking our shingles from below.
He also checked the bath fan. It was venting into the attic instead of outside, adding even more moisture up there.
Why Airflow Matters So Much
I did some reading after the visit. The clearest explanation came from a shingle maker. The GAF guide on why attic and roof ventilation matter says cooking, showers, and even breathing push moisture into the attic. Without good airflow, that moisture gets trapped. Over time, it can hurt your insulation and the roof itself.
The same guide gives a rule of thumb. It suggests at least 1 square foot of vent space for every 300 square feet of attic floor. That space should be split between intake and exhaust. Intake vents sit low, near the soffits. Exhaust vents sit high, near the ridge.
That balance was what we were missing. With the soffits blocked, fresh air could not get in to push hot air out.
What We Changed
We had the insulation pulled back from the eaves. Baffles went in to keep the soffit vents clear. The roof itself had some life left, so we held off on new shingles for now.
The difference showed up fast. The AC cycles off now, and the rooms cool down by evening.
A Few Tips for Neighbors
If you live near Oak Forest Elementary, here is what I would check first:
- Look for daylight at the soffits from inside the attic.
- Check if insulation is stuffed against the roof deck near the eaves.
- Watch for dark stains on the wood near the ridge.
- Notice if upstairs rooms stay hot long after sunset.
None of these mean your roof is failing. They are just clues.
I wish I had climbed that ladder years ago. It would have saved us a few very long summers.
