Inspection and Assessment

Regular inspections are crucial for flat roofs. We conduct detailed assessments to identify potential issues before they become serious problems. Our team checks for common concerns such as:


  • Ponding Water: Areas where water collects can weaken the roof structure.
  • Damaged Membrane: We look for tears or blisters in the roofing material.
  • Flashing Damage: Flashing protects seams and joints; damaged flashing can lead to leaks.


After our assessment, we provide a clear report on the roof’s condition. We make recommendations based on our findings to help you plan for necessary repairs.

Signs of Flat Roof Wear and Damage

Identifying issues with your flat roof early can save us time and money. We should watch for visible leaks, surface erosion, and problems with the roof membrane and flashing. Here are some key signs to look out for.

Visible Leaks and Water Damage


One of the most obvious signs of flat roof damage is visible leaks. We should inspect the interior for water stains or wet spots on ceilings and walls. These indicate that water is penetrating the roof.


Additionally, check for pooling water on the roof surface. Standing water can lead to larger leaks and structural damage. Regular inspections help catch these issues early, protecting your property and preventing costly repairs down the road.


Surface Erosion and Blistering


Surface erosion is another sign you cannot ignore. Over time, weather conditions can wear down the roofing material. This may lead to cracks and blisters forming on the surface.


If you notice these blisters, it's essential to act quickly. Left untreated, they can expand and create further damage. You should also inspect for any smooth or shiny patches that indicate erosion. Maintaining the roof's surface prevents leaks and extends its lifespan.


Membrane Shrinking and Flashing Issues


Membrane shrinking occurs as roofing materials age, which can lead to gaps and leaks. You must regularly check for any signs of this shrinking, especially around edges and seams.


Flashing, which seals joints and edges, can also deteriorate over time. Look for rust, cracks, or missing pieces in the flashing. Properly functioning flashing is crucial to prevent water from seeping into the building. Timely repairs in these areas can maintain the integrity of your flat roof.
