Flat Roof Maintenance

Our Flat Roof Maintenance Process

What does professional flat roof maintenance look like in action? We use specialized tools such as moisture meters and, when needed, thermal cameras to spot trapped water under the surface. Safety matters, so our crews use harnesses, non-slip shoes, and follow OSHA guidelines on every project. Here’s how we approach it for Maryland property owners:

1. Visual inspection and documentation: We start by walking the roof, looking for issues, and taking detailed notes and photos.
2. Clearing debris and cleaning: Branches, leaves, trash, and dirt get cleared away to prevent clogged drains and water buildup.
3. Checking seams, flashings, and penetrations: Seams are a common weak spot, so we check every inch, along with any roof edges or details like skylights.
4. Inspecting drainage and gutters: We flush drains and check for blockages. On flat roofs, one blocked drain can flood a large area.
5. Minor repairs (patches, resealing): If we find small cracks, loose flashing, or minor tears, we handle them right away to prevent bigger problems.
6. Scheduled maintenance plans: Some clients prefer twice-a-year visits (spring and fall). Others need monthly or quarterly checks, especially for busy commercial buildings.

Common Flat Roof Issues We See in Maryland

Our climate is tough on flat roofs. In spring, rain and pollen clog drains. Summer’s heat causes surface materials to expand, and UV rays speed up wear. Winters bring freeze/thaw cycles that can crack membranes and pull seams apart. We see a lot of:

• Standing water or “ponding” (usually from clogged or undersized drains).
• Cracks, blisters, and surface splits in TPO, EPDM, or Modified Bitumen membranes.
• Separated seams or loose flashing around HVAC units, pipes, or skylights.
• Punctures from dropped tools, roof traffic, or falling branches.
• Algae, moss, or organic debris that holds moisture against the surface.

These aren’t rare occurrences; they’re regular calls we get from property owners who notice stains on ceilings or see water pooling after a storm. We’ve helped clients in Baltimore, Columbia, Annapolis, and smaller towns who didn’t realize how quickly small issues can escalate.

Here’s what our maintenance visits typically include:

Our climate, with its mix of hot summers, cold winters, and stormy springs, puts every roof to the test. If you own or manage a building with a flat roof, you’ve probably noticed that even a tiny problem can quickly turn into a big expense.

We’ve seen it firsthand: a clogged drain, a little ponding water, or a single weak seam can lead to water stains on the ceiling or a full-blown leak inside the building. Regular flat roof maintenance stops those problems before they start. Our team at RoofPRO helps Maryland property owners stretch the life of their roof, cut emergency costs, and avoid headaches. That’s why we take roof maintenance seriously.

• A full inspection of the membrane, seams, flashing, and penetrations.
• Removal of leaves, branches, and debris from the roof and drains.
• Minor repairs such as resealing exposed seams or patching cracks.
• Review of drainage flow and recommendations if pooling is present.
• Photos of problem areas with written notes and repair suggestions.

For commercial clients, we also offer optional infrared moisture scans to detect trapped water beneath the membrane. This service is especially helpful for schools, medical facilities, and multi-tenant buildings.
