Essential Winter Care Tips for Flat Roofs

Philadelphia winters can be tough, especially on flat roofs. Heavy snow, ice buildup, and freezing temperatures can lead to costly damage if your roof isn’t properly maintained. At Riley Roofing, we’ve seen how harsh winters can take a toll on flat roofs. That’s why we’ve put together these essential winter care tips to help Philadelphia homeowners and businesses keep their roofs in top shape all season long.

Why Winter Care is Crucial for Flat Roofs

Flat roofs are more vulnerable to winter weather than sloped roofs because they don’t allow snow and water to naturally slide off. This can lead to:

Ponding water that causes leaks
Ice dams that damage roofing materials
Structural stress from heavy snow loads

Proper maintenance can prevent these issues, saving you from expensive repairs and extending the lifespan of your roof.

1. Clear Snow and Ice Regularly

The Problem:

Heavy snow accumulation adds extra weight, putting stress on the roof’s structure. Ice buildup can block drainage systems, leading to water damage.

What to Do:

Use a Roof Rake: Safely remove snow with a long-handled roof rake designed for flat roofs.
Avoid Metal Tools: Never use sharp tools that could puncture the roofing membrane.
Call Professionals: For heavy ice dams or large snow loads, it’s safer to contact Riley Roofing for professional removal.

2. Check for Drainage Issues

The Problem:

Flat roofs rely on internal drains, scuppers, and gutters to remove water. Blockages can cause ponding, leading to leaks and structural damage.

What to Do:

Inspect Drains Frequently: Clear away leaves, debris, and ice that could block water flow.
Ensure Proper Slope: Make sure the roof has the correct slope for effective drainage.
Install Heat Cables: In areas prone to freezing, heat cables can keep drains clear.

3. Inspect for Cracks and Blisters

The Problem:

Freezing and thawing cycles cause roofing materials to expand and contract, leading to cracks, blisters, and membrane separation.

What to Do:

Regular Inspections: Look for visible signs of damage, especially after snowstorms.
Seal Minor Cracks: Use roofing sealant for small issues, but consult Riley Roofing for larger repairs.
Schedule Professional Inspections: An annual winter check-up can catch problems early.

4. Address Ponding Water Immediately

The Problem:

Standing water can weaken the roof structure and lead to leaks. In freezing temperatures, it can turn into ice, causing further damage.

What to Do:

Remove Water Quickly: Use a squeegee or pump to eliminate standing water.
Improve Drainage: Ensure drains are clear and consider adding additional drains if ponding is frequent.
Consult a Roofing Expert: Persistent ponding may indicate deeper structural issues.

5. Monitor Roof Flashings and Seals

The Problem:

Roof flashings and seals around vents, HVAC units, and edges are vulnerable to winter weather. If they fail, water can seep into the building.

What to Do:

Inspect Flashings: Check for rust, cracks, or loose areas.
Re-seal as Needed: Apply roofing-grade caulk to minor gaps.
Call for Repairs: For extensive damage, Riley Roofing can provide expert repairs.

6. Trim Overhanging Tree Branches

The Problem:

Snow-laden branches can break and fall onto the roof, causing damage. Overhanging branches also drop debris that can clog drains.

What to Do:

Prune Before Winter: Trim back any branches that hang over the roof.
Check After Storms: Inspect trees for damage that could pose a risk to your roof.

7. Schedule a Professional Winter Roof Inspection
