10 Marshall roofs flagged after the 2026-06-15 storm.

114 East Main Street

Marshall, MN 56258

heavily weathered. The large light-gray roof surface shows pronounced uneven discoloration, dark blotchy patches across a broad central area, and apparent granule loss consistent with an aging, weathered asphalt roof in need of evaluation.

• · Large dark blotchy patches spread across the central and lower portions of the primary roof plane, consistent with possible algae growth or granule loss
• · Uneven, mottled gray coloration across the main roof surface suggesting non-uniform aging or weathering
• · Contrast between lighter perimeter areas and darker central zones may indicate differential wear or moisture retention

1410 Birch Street

Marshall, MN 56258

moderately worn. Large flat-roof commercial building with a dark membrane surface showing apparent uneven tonal variation, numerous rooftop penetrations, and possible ponding or wear zones across the field of the roof.

• · Numerous rooftop penetrations (vents/HVAC units) visible as white dots scattered across the membrane surface
• · Uneven tonal variation across the membrane — darker patches possible ponding areas or aged sections
• · Parapet wall visible with crenellated/stepped profile along the front edge

268 South 4th Street

Marshall, MN 56258

visibly aged. The main roof surface shows uneven tonal variation and apparent discoloration across the field, consistent with a mature asphalt shingle roof showing general weathering, though low image resolution and monochromatic rendering limit confident damage identification.

• · Uneven tonal variation across main roof plane suggesting non-uniform weathering or possible granule loss in patches
• · Darker mottled areas mid-roof consistent with possible algae or moisture staining
• · Tree canopy casting shadows over portions of the roof, increasing debris and moss risk

448 West Main Street

Marshall, MN 56258

visibly aged. Multiple roofs visible in this dense urban block; the primary structures show dark, uneven tonal variation consistent with aging asphalt shingles, with apparent discoloration and possible granule loss, though low image resolution limits confident assessment.

• · Uneven dark tonal variation across multiple roof planes, possibly consistent with granule loss or algae streaking
• · Several flat or low-slope roof sections visible with apparent discoloration
• · Multiple detached garage or outbuilding structures visible behind main homes

1001 Pearl Avenue

Marshall, MN 56258

visibly weathered. The structure appears to have two distinct roof sections — a dark flat or low-slope section and a lighter-toned large flat section — both showing apparent weathering and surface irregularities consistent with age.

• · Large lighter-toned flat roof section with multiple small dark circular spots consistent with punctures, debris, or penetration points
• · Dark upper roof section with very different tone, possibly a different material or heavily soiled/algae-covered surface
• · Apparent surface texture variation across the lighter roof section suggesting uneven wear or patching

202 North 1st Street

Marshall, MN 56258

moderately worn. This appears to be a large multi-unit residential building with dark asphalt shingles showing apparent uneven tonal variation and possible mild discoloration across multiple roof sections, consistent with mid-to-mature age wear.

• · Uneven tonal variation across the lower roof section, with lighter and darker patches suggesting possible granule loss or differential weathering
• · Numerous rooftop penetrations (vents/stacks) visible across both roof planes, each a potential flashing wear point
• · Apparent darker streaking or shadowing along the center of the lower roof plane, possibly algae streaking or soiling

901 Pearl Avenue

Marshall, MN 56258

moderately worn. The roof appears to be in moderate condition with visible tonal variation and several dark spot anomalies scattered across the surface that warrant closer inspection.

• · Multiple dark circular spots scattered across the upper slope, possibly consistent with debris impact marks, vent caps, or localized granule loss — in-person inspection needed to differentiate
• · Apparent uneven coloration across the field of the roof, suggesting possible differential weathering or granule loss in patches
• · Light streaking or tonal variation running along portions of the slope, possibly consistent with mild algae growth or shadowing

Mall Street

Marshall, MN 56258

moderately worn. The primary gabled roof section appears mid-to-mature aged with uniform but faded gray coloration and some tonal variation, while lower attached sections show a more weathered tan/brown appearance consistent with additional aging or different material.

• · Primary roof section shows uniform gray-blue coloration with possible light fading across the entire surface
• · Lower attached roof sections appear significantly darker and more weathered with an uneven tan-brown texture
• · Apparent tonal variation across the lower roof sections possibly consistent with granule loss or heavy soiling

City Side Townhomes

Marshall, MN 56258

moderately worn. This appears to be a mid-to-mature age asphalt shingle roof on a commercial or institutional building with multiple roof sections showing uneven tonal variation and some apparent weathering across the field of view.

• · Noticeable tonal contrast between darker and lighter roof sections, consistent with uneven aging or possible granule variation across planes
• · Several distinct roof planes visible with what appear to be multiple dormers or shed sections showing darker coloration relative to main field
• · Lighter gray sections on lower slopes appear relatively uniform, while upper/darker sections show more mottled texture

1600-1604 Windstar Street

Marshall, MN 56258

moderately worn. The roof shows visible aging with apparent tonal variation and mild discoloration across multiple planes, consistent with mid-to-mature age asphalt shingles warranting an in-person inspection.

• · Uneven tonal variation across multiple roof planes, with darker and lighter patches suggesting differential weathering or possible granule loss
• · Heavy shadow coverage makes full assessment difficult, but exposed planes show muted gray coloring consistent with aged shingles
• · Multiple valleys visible with apparent darkening at valley intersections, possibly indicating moisture accumulation or debris buildup
