How to Identify When It Is Time for a Flat Roof Replacement
Flat roof systems are seen more often in commercial buildings. But they may also be seen in older houses in some areas. A flat roof has a pitch of 1 to 10 degrees. So, they look flat but have a minimum slope of one-fourth of an inch per foot. This minimum slope facilitates water running off the roof to prevent roof damage.
Large commercial buildings benefit from flat roofs where steep-sloped roofs are impractical. Inspection is more manageable in commercial buildings needing frequent roof inspections. Flat roofs require regular maintenance; failing them may result in roof damage, leading to a need for a roof replacement. They also allow more usable space for installing solar panels or HVAC components. Flat roofs may also be energy efficient depending on the materials used and building location.

Signs on the Rooftop Indicating That It May Need a Flat Roof Replacement
Pools of water
Standing water on the roof indicates that a roof replacement may be needed. The moisture can enter the inner layers and collapse the roof if water pools. The accumulated water means water is not draining off the slope as it should. A roofer can inspect and determine the need for a roof replacement or other roofing services.
Cracks in tar
The tar on the flat roofing system may shrink and crack as time passes, which leads to expansion and protrusion at the roof joints. The changing weather causes alternate freezing and thawing of the flat roof, leading to cracks. Cracks in the tar should warn the homeowner to contact a roofing company.
Damaged flashing
Flashing is the metal edge detailing along the perimeter of flat roofs, which seals the gaps and areas through which water can enter. So, the flashing helps maintain the structural integrity of a building. When the flashing appears bent and looks to be separating from the roof, the property owners need to be aware of the possibility of roof damage that needs repair or a roof replacement.
Loosened fasteners
Fasteners hold the covering material on the roofing structure in place. When any fasteners get loose, they can fall off and cause the covering to move in the wind, eventually exposing the underlying structure to elements that can cause roof damage.
Signs in the Interior of the Building Indicating That a Flat Roof Replacement Is Needed
Water stains on the ceiling
Water stains can develop when water leaks into the building after roof damage. It is a warning that the roof damage is severe enough to need a roof replacement.
Mold on walls and ceilings
Moldy patches on the wall or ceilings indicate that moisture is most likely entering through a defect in the roof.
Bubbling and blistering
Bubbling or blistering on walls or ceilings indicates that water may be trapped beneath the surface of the flat roof. When sunlight heats this trapped moisture, the material near it expands and cracks. Water can seep into the building material and damage the building.
