In Philadelphia, flat rooftops are the norm—and spring is the perfect time to give them a fresh start. After months of harsh weather, your roof could be hiding debris, moisture buildup, or early signs of damage. At Riley Roofing, we specialize in flat roof care and are here to help Philly homeowners prep their roofs for the season ahead.

Here are our top tips for spring cleaning your flat roof like a pro.

Leaves, twigs, dirt, and even trash can pile up over winter. On a flat roof, that debris traps moisture, leading to rot, mold, and membrane damage.

• Use a soft-bristle broom or a leaf blower to gently sweep debris off the surface.
• Avoid dragging tools that could puncture the roofing membrane.
• Don’t forget to check roof corners and around drains where debris collects most.

Flat roofs are especially vulnerable to wear from snow, ice, and standing water.

Here’s what to look for:

• Ponding water that doesn’t drain within 48 hours.
• Blisters or bubbles under the membrane.
• Cracks, splits, or punctures in the surface.
• Soft spots or sagging that indicate moisture beneath the roof layer.

If you see any of these issues, call Riley Roofing for a professional inspection and fast repairs.

Blocked drains are one of the top causes of roof leaks in Philadelphia homes.

• Remove leaves, sediment, and other gunk by hand or with a scoop.
• Pour water into the drain to ensure it flows freely.
• Make sure downspouts are securely attached and directing water away from your home’s foundation.

Riley Roofing can also install drain covers to prevent future clogs.

Flat roofs often have multiple penetrations for HVAC units, skylights, vents, and chimneys—all of which are sealed with flashing and roofing tape.

• Look for cracks or peeling around these areas.
• Check metal flashing for rust or detachment.
• Reapply sealant or contact Riley Roofing to reseal and secure vulnerable areas.
