St. Louis's historic housing stock includes thousands of brick chimneys built between 1900 and 1960. These masonry structures seem fireproof, but intense heat causes internal brick cracking and mortar failure that remains invisible from the exterior. Clay soil settlement common throughout St. Louis already stresses chimney structures. When fire adds thermal shock to existing stress cracks, chimneys can fail catastrophically weeks after the fire is extinguished. Our structural roof fire analysis includes flue inspection and masonry integrity testing that prevents delayed collapse and carbon monoxide intrusion into living spaces.
St. Louis building codes require engineered assessments for fire-damaged structures before re-occupancy permits are issued. The city's inspection department will not approve general contractor estimates or insurance adjuster reports as sufficient structural certification. Property owners need documentation from qualified construction professionals with specific fire damage expertise. Our team works directly with St. Louis building officials and understands their documentation requirements. We provide the certification letters and structural calculations that satisfy permit requirements, preventing delays and allowing you to return home or reopen your business as quickly as safety allows.
