Signs Your Flat Roof Needs Attention
- Water pooling on the roof long after rain has stopped
- Blisters, bubbles or cracks in the roof surface
- Splitting or lifting seams
- Leaks or ceiling stains inside the building
- Damaged flashing at roof edges, vents and rooftop equipment
Catching these early often means a repair instead of a full replacement. We'll inspect the roof and give you an honest recommendation.
