I am a Florida CBO who recently had a housefire that heated the interior of the building to over 900 degrees for approx. 45 minutes. The fire did not penetrate the drywall membrane of the trusses, but did dry-out the core of the drywall (calvinization). There was bat insulation which held residual heat for hours beyond the period of time the fire department extinguished the fire. The trusses have shown signs of charring and discoloration of the gusset plates of the trusses. As a professional, I hired a structural engineer to access the damage and he concluded that the fire compromised the trusses and since more than 30% of the trusses require replacement, this is now a Level - 3 Alteration according Florida Building Code Existing. Insurance company states that the trusses just don't look that bad and they have repaired worse. I have attached a Fire Model for those of you interested in heat damage to trusses. Your comments are welcome and appreciated. Particular comments to why trusses don't have to look so charred to be compromised would be especially helpful.
I believe this is an issue because I have Code Insurance on my policy and if they agree to the truss replacement, they will then have to bring the entire structure up to current code.
