15 Tampa Bay roofs flagged after this week's storm cluster.

visibly worn. Large commercial flat roof showing widespread discoloration, apparent membrane degradation, and numerous white streaking/staining patterns radiating from HVAC units and penetrations, consistent with ponding water drainage paths and possible membrane cracking or coating failure.

• · Extensive white streaking patterns radiating outward from multiple HVAC/mechanical units, consistent with ponding water trails or efflorescence from membrane degradation
• · Uneven patchy gray tonal variation across the membrane surface suggesting inconsistent weathering or prior coating application
• · Multiple large rooftop mechanical units with visible weathering and possible rust staining at their bases

visibly deteriorated. This flat commercial roof shows apparent membrane degradation with multiple lighter-toned patches, possible ponding or delamination areas, and general surface weathering consistent with significant age.

• · Large irregular lighter-colored areas across the main roof field, consistent with membrane delamination or coating failure
• · Multiple HVAC units visible with surrounding areas showing possible discoloration or water staining
• · Uneven tonal variation across the entire roof surface suggesting inconsistent membrane condition

visibly weathered. This flat-roof structure shows substantial discoloration, dark staining, and uneven surface patching across most of the membrane, consistent with significant aging and possible ponding water damage.

• · Large dark stained zones across the central and lower portions of the flat roof membrane, consistent with ponding water or biological growth
• · Upper-right section of roof shows distinctly different coloration (tan/rust tones) compared to the gray main field — possible separate roof section or differential aging
• · Surface appears mottled and uneven throughout, consistent with membrane degradation or prior patching

heavily weathered. The central home's roof shows a deep reddish-brown discoloration across most visible slopes, consistent with heavy algae or biological growth, with significant tree overhang contributing to moisture retention and surface degradation.

• · Deep reddish-brown discoloration across the majority of visible roof slopes, consistent with heavy biological staining or algae/moss growth
• · A separate metal or light-colored panel visible on one section of the roof — possible detached structure or addition with a different roofing material
• · Heavy tree canopy directly over and around much of the roof, increasing debris accumulation and moisture risk

moderately worn. Large commercial flat roof showing visible surface weathering, uneven tonal patterning consistent with membrane aging or ponding water staining, multiple large HVAC units and penetrations, with several darker patchy areas suggesting possible membrane degradation or prior repairs.

• · Widespread horizontal banding/streaking across the main roof deck, consistent with ponding water or membrane surface cracking
• · Multiple darker rectangular patches scattered across the field, possibly indicating prior repairs or localized membrane failure
• · Apparent surface discoloration and tonal variation across the full roof plane suggesting significant age and UV degradation

moderately worn. Large flat commercial building with a white single-ply membrane roof showing visible surface soiling, irregular tonal patterning, and possible ponding water stain areas, consistent with a mid-to-mature age membrane in need of inspection.

• · Irregular gray and white tonal patterning across membrane surface, consistent with dirt accumulation or possible ponding water staining
• · Several HVAC/mechanical units visible on roof with associated curbing and possible flashing areas
• · Faint linear patterns across the membrane surface possibly indicating seam lines or prior repair sealing

moderately worn. Large commercial flat roof with a white reflective membrane showing multiple areas of apparent soiling, discoloration, and possible ponding stains distributed across the field, suggesting mid-to-mature service life.

• · Multiple dark staining patches scattered across the main roof field, consistent with ponding water deposits or biological growth
• · Apparent discoloration concentrated in a cross-shaped pattern near the center of the larger roof section
• · Several circular dark spots visible across the membrane, possibly around roof penetrations or drains indicating pooling

moderately weathered. Large commercial flat roof showing widespread surface weathering, apparent streaking and discoloration across most of the membrane, with numerous HVAC units and penetrations that increase leak-point risk.

• · Horizontal streaking patterns consistent with membrane weathering or surface oxidation across the majority of the roof field
• · Uneven tonal variation throughout — darker blotchy areas interspersed with lighter zones, possibly indicating moisture retention or prior repairs
• · Multiple large HVAC rooftop units creating numerous penetration points and flashing exposure
