Winter in Pittsburgh is no joke. Between heavy snow, freezing rain, high winds, and rapid temperature swings, your roof takes a beating from December through March. A little preparation now can prevent leaks, ice dams, and expensive repairs once the cold weather hits. Here’s a complete guide to getting your roof winter-ready and making sure your home stays dry, safe, and energy-efficient all season long.

How to Prep Your Roof for Pittsburgh’s Winter

Why Winter Roof Prep Matters

Pittsburgh winters bring constant moisture and fast freeze-thaw cycles. As temperatures drop at night and warm up during the day, your roof expands and contracts. If there are hidden issues like loose shingles, soft decking, clogged gutters, or poor ventilation, winter weather will make those problems much worse. Preparing ahead of time helps extend your roof’s lifespan, protects your attic’s insulation, and prevents things like ice dams and leaks that often go unnoticed until spring.

How to Prep Your Roof for Pittsburgh’s Winter

Inspect Your Shingles Before the First Snowfall

Shingles are the first line of defense against winter weather. Damaged or missing shingles create weak points where melting snow can seep into your roof system. Take time to visually inspect your roof from the ground or have a professional do a full inspection.

Look for:

• Missing or lifted shingles

• Cracked or curling shingles

• Granule loss

• Exposed nail heads

• Visible sagging or soft spots

Catching these issues early prevents water from freezing under shingles and causing leaks.

Clear Gutters and Downspouts

Gutters clogged with leaves or debris prevent melting snow from draining properly. When water backs up and refreezes, it forms heavy ice dams along the roof edge. These ice dams can push water under shingles and cause interior leaks and drywall damage.

Before temperatures drop:

• Remove all leaves

• Flush gutters with water

• Ensure downspouts are directing water away from the home

Winter storms happen fast in Pittsburgh, and clogged gutters are one of the top causes of ice dams.

Your attic plays a bigger role in winter roof protection than most people realize. Poor ventilation traps warm air inside the attic, melting the snow on the roof. When that melted snow refreezes along the cold roof edge, ice dams form. Proper insulation and ventilation work together to keep your roof surface cold and consistent.

Signs of poor ventilation include:

• Frost forming inside the attic

• Musty odors

• Uneven melting on the roof

• Mold or moisture staining on rafters

Good airflow extends the life of your shingles and helps regulate indoor energy costs.


Trim Back Overhanging Branches

Trees add shade and beauty, but during winter they can become a major risk. Heavy snow and ice can cause branches to snap and fall onto your roof, damaging shingles and gutters.

Trim branches that:

• Hang directly over the roof

• Touch or scrape against shingles

• Drop excessive leaves into gutters

Keeping trees trimmed also reduces the risk of animal activity on your roof during colder months.


Seal Roof Penetrations and Check Flashing

Chimneys, skylights, and vent pipes are common areas where winter leaks start. The flashing around these penetrations can loosen over time or develop gaps that allow water to sneak in.

Before winter:

• Check chimney flashing

• Inspect around skylights

• Look at all vent pipe seals

• Reseal any visible gaps or cracks

A small amount of preventative sealing goes a long way in keeping your attic dry.


Schedule a Professional Roof Inspection

Even if everything looks okay from the ground, there may be hidden issues only a trained eye can spot. A professional winter prep inspection includes checking your roof system, gutters, attic ventilation, insulation levels, and identifying areas that may fail under winter stress.

Winter storm repairs can be costly, so an inspection before the season hits is a smart investment.


Prepare for Winter Emergencies

Pittsburgh weather can be unpredictable. Having a winter roof preparedness kit can save you time (and stress) during a storm.

Keep on hand:

• A roof rake for clearing snow

• Spare ice melt (safe for shingles)

• Flashlight and batteries

• Extra attic insulation if needed

• Emergency phone numbers for roofing services

Being prepared ensures small issues don’t turn into big problems during a blizzard.
