Frequently Asked Questions

Rotted sheathing hidden under old shingles causes new material to fail early. Older St. Louis neighborhoods like Florissant and Ballwin often have compromised decks that need replacement before installation. Deck inspection and sheathing replacement are part of the install process, not an upsell added after tear-off.

Freeze-thaw cycles, hail events, and spring rainfall volume all accelerate shingle failure here. St. Louis sits in a high-frequency hail corridor, and temperature swings cause thermal expansion issues metal roofs must account for. Ventilation problems amplify heat damage during summer, shortening lifespan further.

Full replacement quotes include a ventilation audit — improper attic airflow causes premature shingle failure most contractors skip. The quote covers tear-off, deck inspection, sheathing replacement if needed, new material, and proper ventilation assessment. This prevents the hidden cause of early roof failure.

Repair works when damage is localized and the deck underneath is solid. Attic inspection reveals moisture intrusion and deck rot that makes patching pointless — new material over compromised structure fails within a season. If the deck's compromised or shingles are past their cycle, replacement prevents throwing money at a temporary fix.

Improper fastening and missing thermal expansion engineering cause panel movement failures. St. Louis temperature swings require panel profiles and fastening systems that account for expansion and contraction. Storm-chaser crews skip this step, leaving penetrations that leak and panels that separate after one season.

Sizing is based on roof pitch and square footage, not a standard 5-inch default. St. Louis spring rainfall volume overwhelms undersized gutters, causing fascia rot and foundation wash. Properly engineered sizing prevents overflow failures that show up as basement seepage and erosion around the foundation.

Ice damming pulls gutter hangers loose, especially in Florissant and South City. Hangers spaced too far apart can't handle ice load, and improper slope prevents drainage before freezing occurs. Structural repair re-spaces hangers and corrects slope, not just seals visible leaks.

The contractor documents damage during the adjuster inspection, catching what adjusters may miss. This includes hidden deck damage, ventilation failures, and secondary issues like gutter and flashing damage. Claim-ready documentation gives homeowners an advocate before the check gets written, not after.

Moisture intrusion visible from the attic reveals deck rot that makes surface patching pointless. A patch over rotted sheathing fails within months because the structure underneath can't hold fasteners. Inspection-first repair prevents patch-over-rot situations that waste money and fail early.

Flat roof membrane selection depends on building drainage design and ponding risk. St. Louis spring rain events cause ponding on improperly drained flat roofs, especially in Clayton and Creve Coeur commercial properties. Membrane type, seam placement, and drainage slope are all engineered to building-specific conditions.

Trapped heat in poorly ventilated attics cooks shingles from underneath, causing premature aging and granule loss. St. Louis summer heat amplifies this effect on homes built in the 1970s–1990s with insufficient ridge or soffit vents. Ventilation audits identify airflow problems before new shingles go down.

Seamless gutters are formed on-site with no joints except at corners, reducing leak points. Sectional gutters use pre-cut pieces with seams every 10 feet that separate over time. Seamless systems last longer in St. Louis freeze-thaw cycles because there are fewer failure points where ice can separate joints.
