5 Late‑Summer Home Projects to Tackle

As summer winds down here in Connecticut, now is a golden opportunity to tackle home improvement projects with maximum return. Late summer offers warm, dry days that are perfect for outdoor work before the wet chill of fall sets in. Here are five smart projects every homeowner should consider while there’s still daylight (and deck furniture to enjoy).

1. Exterior Painting or Staining

August and early September give you cooler, less humid weather which are ideal conditions for paint and stain to dry evenly without peeling or blistering. Whether it’s freshening up siding, restoring your deck, or repainting trim, late summer ensures the new finish cures properly for a long-lasting result.

2. Roof Inspection & Minor Repairs

Summer storms can loosen flashing and shingles, and if left unchecked, those small issues become leaks once the snow flies. A roof check now helps you avoid water damage and insulation headaches. Plus, contractors in Connecticut can often still fit this work into their schedules before fall gets busy.

3. Gutter Cleaning & Guard Installation

Leaves haven’t started falling yet, so now’s the best time to clean out your gutters and downspouts. While you’re at it, consider adding gutter guards. This prepares your home for leaf season and keeps you off the ladder in cold weather. It’s an investment you won’t regret. 

4. Window Sealing or Replacement

Drafty windows? Now’s the time to replace or seal them before the heating season hits. Caulking and weatherstripping stop cold air in its tracks, while double‑pane, energy-efficient replacements reduce your heating bills. Connecticut homeowners can tap into rebate programs for these upgrades. Check out Energize CT for information.

5. Driveway Sealing or Repairs

Sealcoating your asphalt driveway protects it from salt, freeze-thaw cycles, and ice damage, just what Connecticut winters bring. Asphalt requires daytime temps above 50 °F to cure; late summer givesplenty of time before cooler weather sets in.

Late summer may feel like the calm before the leaf blowers, but it’s also prime time for smart homeowners to take care of the jobs that will protect and preserve their homes into the colder months. A little time and effort now can go a long way toward keeping your home dry, warm, and efficient all season long.

Ventilation 101: How to Keep Your Attic from Turning Into a Sauna

Most homeowners don’t think about their attic unless something goes wrong. But during the hot, humid summer months in Connecticut, poor attic ventilation can cause a lot of problems. Some you’ll feel in your cooling bills, and others you might not notice until it’s too late.

Here’s why proper attic ventilation matters and how to know if your home needs an upgrade.

Why Your Attic Needs to Breathe

Your attic should be the same temperature as the air outside. That might sound surprising, but it’s true. In the summer, without proper airflow, your attic can easily reach 130°F or higher. That heat doesn’t just stay in the attic - it radiates down into your living space, forcing your air conditioner to work harder and driving up energy costs.

Hot, stagnant air can also cause your roofing materials to age prematurely. Shingles can blister, underlayment can warp, and moisture can build up, leading to mold, mildew, and even wood rot.

Good ventilation helps control both heat and moisture, keeping your attic and roof in better shape, and your home more energy-efficient.

The Basics of a Ventilation System

A well-ventilated attic has two things: intake and exhaust. These work together to create a continuous flow of air.

• Intake vents (usually located in the soffits under your roof overhang) pull fresh air into the attic.

• Exhaust vents (at the roof ridge, gables, or high up on the roof slope) allow hot, humid air to escape.

This system relies on the natural movement of air—cool air in, hot air out.

Common Ventilation Types

• Ridge vents: Run along the peak of your roof and are often paired with soffit vents. They’re effective and barely noticeable from the street.
  Soffit vents: Located under your eaves, they bring in cool outside air.

• Gable vents: Installed on the walls of the attic, often used in older homes.

• Powered attic fans: Use electricity to actively pull hot air out. These can be helpful but aren’t always necessary if passive ventilation is working properly.

Signs of Poor Attic Ventilation

• Your upstairs rooms are always hotter than the rest of the house.

• You notice high energy bills in the summer.

• Your roof shingles are curling or deteriorating faster than expected.

• There’s mold or a musty smell in the attic.

• You see frost or condensation in the attic during winter (yes, ventilation matters year-round).

Here in Connecticut, we deal with humid summers and cold winters, which means both heat and moisture are issues. That makes proper attic ventilation even more important. It’s not just about comfort, it’s about protecting your roof, improving air quality, and saving on long-term energy costs.

If you’re unsure whether your attic is properly ventilated, a quick inspection by a professional can help. It’s one of those home systems that’s easy to overlook, until it’s not.

Why Is My Roof Streaky? Here’s What You Need to Know

If you’ve noticed black streaks, moss, or patches of discoloration on your roof, you’re not alone. These stains are common and may seem like a minor issue at first, but they can lead to bigger problems if ignored.

The most common cause of roof streaking is algae, specifically, a type called Gloeocapsa magma. It spreads through airborne spores and tends to thrive in warm, humid environments. Once it lands on your roof, it starts to grow, especially on shaded areas where moisture hangs around. Over time, you might also see moss or lichen, which can cause even more damage by holding moisture against the surface of your shingles.

These growths aren’t just cosmetic. Algae and moss can wear down your roofing materials, shorten the life of your shingles, and in some cases, lead to leaks or water damage. That’s why regular roof cleaning is important.

So, what’s the best way to clean your roof? It’s not a job for a pressure washer. In fact, using high-pressure water can damage your shingles and lead to costly repairs. Professional roof cleaners use a method called soft washing, which combines low-pressure water with specially formulated cleaning solutions that safely remove algae, moss, and dirt without harming your roof or surrounding landscaping.

A proper roof cleaning usually takes just a few hours and can dramatically improve the look and health of your roof. It also gives a roofing professional the chance to inspect for other potential issues like cracked flashing, loose shingles, or clogged gutters that could cause problems later.

It’s also important to pay attention to any warning signs that there might be a deeper issue. If you notice a musty smell in your attic, signs of water damage on your ceiling, or poor ventilation, there may be moisture getting inside. That could mean your roof needs more than just a cleaning. It might be time to check insulation, repair parts of the roofing structure, or even have the roof replaced. 

Having your roof inspected and cleaned at least once a year, especially in the spring or early summer, is a smart habit. It helps catch small issues before they become bigger problems, protects your home, and keeps your roof looking its best.

And remember, roof work can be dangerous. Between the height, the angle, and the risk of damaging your shingles, it’s not something you want to tackle on your own. Always call a licensed professional who has the right tools, training, and safety equipment to get the job done right.

Your roof is a big part of what keeps your home safe and dry. A little regular care goes a long way in keeping it that way.
