10 Fond du Lac roofs flagged after the 2026-07-01 storm.

530,532 Luco Road

Town of Fond du Lac, WI 54935

moderately worn. The two central homes display tile roofs with a notable pinkish-purple tonal cast across large portions of the field, consistent with fading, discoloration, or possible algae/biological growth on aging tile surfaces, warranting an in-person inspection.

• · Pronounced pinkish-purple discoloration covering the majority of the main roof fields on both center structures, possibly consistent with algae or lichen growth on concrete tile
• · Contrast between lighter gray hip/ridge areas and darker discolored field tiles suggests uneven weathering
• · Roof edges and ridgelines appear intact with no obvious large-scale missing tile sections visible

37 5th Street

Fond du Lac, WI 54935

visibly aged. The center home's multi-plane roof shows apparent uneven coloration and tonal variation across its several roof sections, consistent with a mature asphalt roof showing differential weathering and possible granule loss.

• · Distinct color variation across roof planes — some sections appear darker gray-brown while others show a lighter muted purple-gray tone, suggesting uneven weathering or aging
• · Multiple roof planes with visible valleys meeting at center, increasing flashing/leak risk areas
• · Apparent tonal patchiness across the main roof field consistent with granule loss or surface degradation

513 Sherwood Avenue

Fond du Lac, WI 54935

moderately worn. The building appears to be a commercial or institutional structure with a low-slope membrane roof showing apparent discoloration and uneven tonal variation across the surface, suggesting moderate wear or possible ponding areas.

• · Uneven color variation across the membrane surface — lighter at edges, darker/more saturated toward center — possibly consistent with ponding water or differential aging
• · Single central roof penetration visible (likely an HVAC stack or vent)
• · Perimeter edge appears to have a raised parapet or edge flashing detail with darker fascia band

63 5th Street

Fond du Lac, WI 54935

visibly aged. The bright red metal roof shows apparent tonal variation and possible surface oxidation or fading across multiple panels, suggesting mid-to-mature age with some wear, though resolution limits precise damage assessment.

• · Uneven color variation across the red metal surface, consistent with possible oxidation or fading in patches
• · Roof appears to have multiple planes with visible seam lines running across the surface
• · Small white feature visible near center of roof — possible vent or penetration

617 East Scott Street

Fond du Lac, WI 54935

moderately worn. The roof displays a notably uneven purplish-mauve coloration with tonal variation across the main field, suggesting possible algae discoloration or granule inconsistency consistent with mid-to-mature age shingles.

• · Pronounced tonal variation across the main roof field — lighter upper section and darker purplish lower section may indicate uneven granule wear or possible algae/discoloration
• · Apparent color banding visible across the slope, possibly indicating different aging rates or a prior partial re-roof
• · Roof surface color differs noticeably from neighboring homes' gray roofs, suggesting heavier weathering or staining

88 Prestige Circle

Fond du Lac, WI 54935

moderately worn. The roof shows apparent uneven coloration across its surface with a notable two-tone appearance suggesting differential weathering or aging, warranting an in-person inspection.

• · Distinct two-tone color split visible across the roof surface — upper portion appears darker gray while lower portion shows a lighter purple-gray tone, possibly indicating a partial re-roof or differe
• · Several small white dots visible on the lower slope, possibly penetrations or vents
• · One larger white square visible near center of roof, consistent with a skylight or HVAC unit

528 Sherwood Avenue

Fond du Lac, WI 54935

moderately worn. This long, low-slope commercial or multi-unit residential building shows a two-toned roof with a notable color contrast between the upper gray section and lower pink/lavender section, suggesting either differential aging, prior partial resurfacing, or significant discoloration ac

• · Pronounced two-tone color division across the roof field — upper half appears gray/weathered, lower half shows a distinct pink/lavender tone, consistent with differential aging or a prior partial repa
• · Apparent uneven surface texture across the gray portion suggesting possible granule loss or surface weathering
• · Overall roof color variation and mottling consistent with a mature-age asphalt surface

29 5th Street

Fond du Lac, WI 54935

moderately worn. The central home's roof shows a dark, unevenly toned surface with possible discoloration and granule wear consistent with a mid-to-mature age roof, warranting closer inspection.

• · Uneven tonal variation across the main roof surface, possibly indicating differential granule loss or algae staining
• · Darker central section contrasting with lighter perimeter edges, suggesting uneven weathering
• · Adjacent property to the right shows visibly multi-toned roof with distinct color patches, possible prior partial repair

562 East Scott Street

Fond du Lac, WI 54935

visibly aged. The main roof appears to be a mature asphalt shingle roof with an unusual pinkish-purple discoloration across the primary field, suggesting significant weathering, possible algae staining, or granule degradation; moderate tree overhang adds debris and moisture risk.

• · Pronounced pinkish-purple tonal shift across the entire main roof field, consistent with heavy discoloration or granule loss/oxidation
• · Apparent single penetration visible near the center of the roof
• · Heavy tree canopy overhanging the front-left and rear portions of the roof, increasing debris and moisture retention risk

224 West Follett Street

Fond du Lac, WI 54935

moderately worn. The central home's roof shows apparent mid-to-mature age with uneven tonal variation and possible discoloration across multiple planes, suggesting a roof in the latter half of its service life.

• · Uneven color across roof planes — darker patches on certain slopes consistent with possible algae or granule loss
• · Purplish-gray tonal variation on the main front slope, possibly indicating differential weathering or granule depletion
• · Roof appears to have multiple intersecting planes suggesting complexity and more valley/flashing exposure
