The Fifth Circuit certified unanswered questions on the concurrent causation doctrine to the Texas Supreme Court. Overstreet v. Allstate Vehicle & Prop, Ins. Co., 2022 U.S. App. LEXIS 13582 (5th Cir. May 19, 2022).

The insured alleged that a hail storm damaged his roof. The roof was three years old when he purchased a policy from Allstate. An adjuster sent by Allstate valued the loss at $1,263.123, less than the policy deductible. Allstate contended that the roof damage was due to uncovered causes, namely a combination of wear and tear and earlier hail storms that hit the roof before the insured purchased the policy. The insured disagreed because the roof had never leaked before the hail storm, but only after the storm. The insured's expert inspected the roof and determined it had been damaged by hail. The district granted Allstate's motion for summary judgment because the insured had not carried his burden of proving how much damages came from the hail storm alone.
