When Summer Heat Hits Hard… Inside Your House



If your upstairs rooms feel like a sauna in July, or if your AC seems to run nonstop with little relief, the problem might not be your HVAC system. It might actually be your roof.

Homeowners are often surprised to learn just how much roof design, materials, and ventilation affect indoor temperatures. A poorly ventilated attic can trap heat, turning your upstairs into an oven and forcing your cooling system to work overtime. Let’s break down why that happens and what you can do about it.

The Hidden Heat Trap: Your Attic

Your attic acts as a buffer between your roof and your living space. When it’s working properly, it allows hot air to escape and keeps your indoor temperature more stable. But in a lot of older homes, or homes with aging roofs, ventilation just wasn’t a priority.

Here’s what can go wrong:

• Hot air has no way to escape. Without ridge vents or soffit vents, heat builds up fast.

• Your insulation can’t keep up. Even good insulation can only do so much when the attic is 120+ degrees.

• Moisture becomes an issue. Trapped air = trapped humidity, which can lead to mold and damage.

The result? A hot, humid attic that radiates heat downward and into your home.

Roofing That Works With Your Home, Not Against It

At Brown Roofing, we replace roofs with complete roofing systems, not just shingles. When we’re on the job, we make sure your attic can breathe and your home can handle whatever the Connecticut summer throws at it.

Here’s what we install:

• Ridge vents at the top of the roof to let hot air rise and escape

• Soffit vents to bring in cooler air from below and keep the cycle going

• IKO Dynasty shingles in lighter colors like Frostone Gray to reflect more sunlight

• Velora One synthetic underlayment for superior heat resistance

• And proper insulation/sealing guidance to keep your attic functioning efficiently

Signs You Have a Ventilation Problem

You might not spend a lot of time in your attic, but the symptoms can show up throughout your home:

• Hot, stuffy upstairs rooms

• Sky-high energy bills in summer

• AC running constantly without cooling properly

• Curling shingles or moisture damage in your attic

• Ice dams forming in winter (yes — poor ventilation causes issues year-round!)

What to Do Next

If your attic is unbearably hot, or your home just doesn’t stay cool in summer, it’s time for a professional roof inspection. At Brown Roofing, we don’t just look at the surface. We check:

• Shingle condition

• Attic ventilation

• Underlayment and insulation

• Roof age and performance history

Sometimes, better ventilation or minor repairs can help. Other times, your roof may be past its prime and holding your whole home back. Either way, we’ll give you honest, expert advice and clear next steps.
