1. Ensure Your Roof Has Proper Drainage

Flat roofs don’t shed water like sloped roofs, making drainage a top priority. Without it, water can collect and cause leaks or structural damage.

✅ Keep Drains and Scuppers Clear – Debris like leaves, dirt, and twigs can clog drains and prevent water from flowing off your roof. Regular cleaning—especially in the fall—is essential.

✅ Check for Ponding Water – If water remains on your roof for more than 48 hours after rain, it may be a sign of poor drainage. A roofing professional can help determine if regrading or additional drains are needed.

✅ Install or Maintain a Tapered Insulation System – While flat roofs may look level, they should have a slight slope to guide water toward drains. If your roof doesn’t drain properly, adding tapered insulation can help.

2. Prevent Ice Dams in the Winter

Philadelphia winters bring freezing temperatures that can cause ice dams, leading to water backup and roof damage. Ice dams form when heat escapes from your home, melting snow on your roof, which then refreezes at the edges and blocks proper drainage.

✅ Improve Your Roof’s Insulation – A well-insulated roof prevents heat from escaping, reducing the chances of snow melting unevenly and refreezing at the edges.

✅ Seal Air Leaks – Gaps around vents, skylights, or chimneys can allow warm air to escape, contributing to ice dam formation. Sealing these areas helps maintain a consistent temperature on your roof.

✅ Use Roof-Safe Ice Melt – If ice dams form, avoid using rock salt, which can damage roofing materials. Instead, use calcium chloride or a roof-safe de-icing product.

3. Apply a Protective Roof Coating

A high-quality roof coating can extend the life of your flat roof and protect it from water damage.

✅ Waterproof Coatings – These create a barrier that helps prevent moisture penetration and leaks.

✅ Reflective Coatings – These help regulate roof temperature, reducing freeze-thaw cycles that lead to ice dam formation.

✅ Seal Small Cracks – Roof coatings can help prevent minor cracks from turning into larger issues that allow water infiltration.

4. Schedule Regular Roof Inspections

The best way to prevent serious roofing problems is to schedule professional inspections at least twice a year—before and after winter.

✅ Spring Check-Up – Identify and repair any winter damage, like small cracks or weakened drainage areas.

✅ Fall Maintenance – Ensure your roof is ready for winter by clearing drains, checking insulation, and making necessary repairs before freezing temperatures arrive.

5. Remove Snow & Ice Safely

Philadelphia homeowners must be proactive in managing snow accumulation on their flat roofs.

✅ Use a Roof Rake for Snow Removal – A long-handled rake can help clear excess snow without damaging roofing materials.

✅ Hire a Professional for Heavy Snow Removal – If snow builds up too much, it can stress your roof. A professional can safely remove it without causing damage.

✅ Avoid Using Metal Tools – Shovels or ice picks can puncture roofing material, leading to leaks. Use plastic or rubber tools designed for roof maintenance.
