While they fulfill the same purpose, flat roofs differ from sloped residential roofing systems and have different care, maintenance and inspection requirements. Here’s what typically happens during a flat roof inspection.
Roof leaks usually happen in areas where flashing is installed. These strips of metal or membrane may look simple, but to get a watertight seal, they need to be installed by a considerably skilled roof installer.
Flashing is installed on breaks on the roofing plane or where an object penetrates the roof. Rubber boots are a type of flashing that’s installed where vent pipes and similar protrusions penetrate the roof. During a roof inspection, these areas are thoroughly inspected. Damaged flashing is marked for repair once the inspection is completed.
Vertical surfaces like walls, chimneys and dormers meet the roof at some point. Single-ply roofing is typically installed in such a way that it covers the meeting point with a 90-degree overlap. Folds and overlaps are not a problem with rigid roofing materials like sheet metal used in metal roofing installation. It’s a different case with flat roofs. Depending on the material, folds may result in cracks over time, which will need to be repaired as soon as possible.
Punctures are not easily spotted unless someone with a trained eye is looking for them. Punctures can occur due to sharp stones, debris or footwear with sharp edges, and can be problematic, especially on ballasted single-ply roofs. Since this type of roofing system has loosely laid outer material, punctures would allow water and wind intrusion, which could easily spread throughout the roof.
Fortunately, once punctures are found, repair work is relatively simple. Patches can be installed over the punctures. These patches are made of the same material as the outer roofing and can be installed using heat, adhesive or a combination of both. When conducted by a capable roofing contractor, repairs can done as soon as possible, minimizing risks of greater damage.
