Hensel Phelps Construction Co. sued Royal American Services, Inc. and Arrowall Company in Harris County, Texas, after a January 2012 water intrusion event at the Houston Methodist Hospital Outpatient Center allegedly caused property damage. The pleadings frame the dispute around whether Royal American’s roof work and Arrowall’s door-related scope contributed to the leak, along with claims tied to warranties and indemnity obligations. In the trial court, the defendants sought leave to designate Houston Methodist Hospital, Broaddus & Associates, and WHR Architects, Inc. as responsible third parties, asserting the damages were caused or contributed to by others rather than the defendants’ acts or omissions.
After a bench trial, the trial court rendered a take-nothing judgment in favor of Royal American, and the First Court of Appeals of Texas affirmed in a 2017 decision. The appellate record centers on a construction-defect fact pattern involving a roof area and a door leading to the roof, with competing positions on whether flashing was installed, removed, or implicated in the water infiltration. In this context, forensic engineering is a useful term for the fact-focused examination of building components and installation details such as roof-to-wall transitions, flashing conditions, and door interfaces used to assess competing causation explanations tied to the reported water intrusion and resulting damage.
A severe rain event was reported to have led to water intrusion and property damage at the Houston Methodist Hospital Outpatient Center in Harris County, Texas. The dispute that followed focused on building-envelope details tied to a rooftop area, including a door leading to the roof and the presence or absence of roof flashing around that doorway. The parties’ later filings framed the event as a causation dispute about what allowed water to enter and what work scopes were connected to those conditions.
Hensel Phelps Construction Co. filed suit against Royal American Services, Inc. and Arrowall Company in the 11th Judicial District Court in Harris County. The pleadings alleged negligent performance of work at the outpatient center, breach of express warranties, and failure to satisfy indemnity obligations tied to the water intrusion event. The defendants, in turn, disputed causation and responsibility for the claimed damage.
With the case set for trial on June 15, 2015, the defendants moved for leave to designate Houston Methodist Hospital, Broaddus & Associates, and WHR Architects, Inc. as responsible third parties. The motion described Royal American’s scope as roof installation and Arrowall’s scope as door installation, and it advanced competing explanations for how water infiltration occurred, including contentions about flashing and door configuration. These filings narrowed the litigation toward allocation of responsibility for the water intrusion and resulting damage.
The First Court of Appeals of Texas affirmed a take-nothing judgment for Royal American after a bench trial that proceeded only against the roofer, and it noted a pretrial settlement between Hensel Phelps and Arrowall for $110,000. The opinion also states the trial court awarded Royal American $4,500 in damages, plus prejudgment interest and attorney’s fees, on a counterclaim for unpaid repair work.
The court described competing technical proof: Hensel Phelps’s engineer pointed to the claimed lack of anchor holes for flashing and said water could possibly enter through roof-membrane conditions, while Royal American’s engineer relied on a membrane impression and sealant or adhesive at the threshold to support that flashing had been installed and later removed; the opinion also discussed investigation testimony citing a dark impression and residue viewed as consistent with prior flashing and acknowledging the conclusion was preliminary without further requested investigation, with analysis consistent with a forensic engineering approach to roof flashing and door-interface conditions.

The court described competing technical proof: Hensel Phelps’s engineer pointed to the claimed lack of anchor holes for flashing and said water could possibly enter through roof-membrane conditions, while Royal American’s engineer relied on a membrane impression and sealant or adhesive at the threshold to support that flashing had been installed and later removed; the opinion also discussed investigation testimony citing a dark impression and residue viewed as consistent with prior flashing and acknowledging the conclusion was preliminary without further requested investigation, with analysis consistent with a forensic engineering approach to roof flashing and door-interface conditions.
Engineering Expert Witness (Plaintiff and Defense)
Plaintiff: The record identifies an engineering witness who testified for Hensel Phelps on whether roof flashing was installed at the rooftop door threshold. The testimony described relying in part on physical indicators, including the claimed absence of anchor holes that would be expected if flashing had been fastened. The witness also discussed observed conditions in the roof membrane and stated that water could possibly enter through those conditions, using cautious wording rather than certainty.
Defense: The record identifies an engineering witness who testified for Royal American and opined that flashing had been installed at the threshold. The testimony referenced an impression pattern in the roof membrane and observations of sealant or adhesive consistent with flashing under the door threshold. The witness connected the water intrusion to the absence of flashing at the time of the storm and attributed that absence to later removal rather than an initial failure to install.
Building-Envelope Investigation Expert Witness (Fact Witness)
The record describes testimony from a Zero/Six Consulting employee who participated in the post-event investigation. The witness testified that certain observations, such as a dark impression consistent with prior flashing placement and residue consistent with earlier installation, supported a view that flashing had existed at one time but was later removed by an unknown party. The witness also testified that the conclusion was characterized as preliminary and that additional investigation would have been needed to reach a stated level of certainty, but further work was not requested.
Architectural Engineering Expert Witness
An architectural engineering expert is often engaged in water intrusion disputes involving roof-to-door transitions to assess interface detailing, drainage pathways, and how roof assemblies tie into door thresholds. They commonly compare as-built conditions to intended details and evaluate how minor configuration changes can affect water management under heavy rainfall. Their work typically supports causation analysis focused on building-envelope performance.
Forensic Engineering Expert Witness
A forensic engineering expert witness is often engaged to integrate the observed roof conditions, threshold interface details, and the sequence of work into a structured causation analysis. In water intrusion disputes, they typically review investigation notes and photos, assess competing explanations such as missing flashing versus membrane discontinuities, and explain how each scenario could relate to the timing of reported leaks.
Prioritize causation proof tied to observable site conditions (Houston, Texas).
This record shows the dispute turning on physical indicators at a roof-to-door threshold, including whether flashing was present and what membrane impressions or residue suggested. When the fact pattern depends on competing explanations, attorneys benefit from locking down what was observed, when it was observed, and by whom. Framing those observations in a forensic engineering approach can help keep causation arguments anchored to verifiable conditions rather than broad narratives.
Manage “responsible third party” strategy early to protect allocation defenses (Harris County).
The defendants pursued designation of additional parties as responsible third parties, which can affect how fault is argued even when claims are pursued against a narrower set of defendants at trial. Counsel should align the designation theory with specific, source-supported causation pathways, not just general references to other participants. In water intrusion disputes, that often means tying design roles or site changes to the same interface details under review in the engineering testimony.
Treat bench-trial posture as a key driver of appellate risk (Texas First Court of Appeals).
After a bench trial, the trial court’s resolution of conflicting testimony can be difficult to disturb on appeal when the record supports more than one view of the evidence. Attorneys should plan for that deference by building a clear record on disputed technical points and addressing the opposing theory directly. Where the dispute resembles forensic engineering work flashings, thresholds, membrane conditions precision in terminology and exhibits matters.
Address counterclaims and contract payment issues alongside defect claims (Houston area projects).
The record reflects that the defendant recovered on a counterclaim for unpaid repair work, along with prejudgment interest and attorney’s fees, reinforcing that payment disputes can materially affect final outcomes. Plaintiffs should evaluate lien waivers, change orders, and payment documentation early, while defendants should align repair invoices and scope narratives with the work actually performed. Keeping the payment story consistent with the technical causation story avoids internal tension in the proof.
Use settlement and party narrowing deliberately, while preserving the core liability theory (Texas construction disputes).
The case posture included a pretrial settlement with one defendant and proceeded to trial against another, which can streamline proof but also concentrates causation disputes on fewer actors. Attorneys should reassess how exhibits, testimony, and the remaining theory fit together once parties exit, especially when the central dispute is a roof interface condition. A carefully bounded forensic engineering narrative focused on what the physical evidence supports can reduce overreach and improve credibility.
The Hensel Phelps v. Royal American Services dispute closed with a take-nothing judgment for Royal American that was affirmed on appeal, ending the case with Royal American recovering on an unpaid repair-work counterclaim for $4,500 plus prejudgment interest and attorney’s fees, while Hensel Phelps had reached a pretrial settlement with Arrowall for $110,000. At its core, the litigation turned on a narrow causation fight tied to a rooftop door threshold and whether flashing was present at the time of a January 2012 storm, along with how later changes and site conditions were interpreted. The outcome reflects how construction defect and water intrusion cases can rise or fall on the trial record developed around specific physical conditions and the court’s resolution of conflicting testimony.
For attorneys evaluating similar Houston, Texas water intrusion disputes, the record shows why technical proof must stay anchored to what was observed at the roof-to-door interface, including impressions, sealant or adhesive residue, and other site indicators referenced in testimony. In this setting, forensic engineering is best understood as the structured review of physical conditions and work sequence used to evaluate competing explanations for water entry, rather than a label automatically applied to every engineering witness. When the dispute is framed around whether flashing existed and how the roof membrane and threshold details performed under heavy rainfall, carefully bounded technical testimony and clear documentation can help keep causation arguments precise and consistent with the record.
What was Hensel Phelps v. Royal American Services about in Houston, Texas?
It was a construction dispute arising from a January 2012 water intrusion event at the Houston Methodist Hospital Outpatient Center. The case focused on whether work at a rooftop door threshold and related roof flashing conditions were connected to the reported leak and resulting damage. The litigation also involved warranty, negligence, and indemnity-related claims in the trial court record.
What was the final outcome of the case?
After a bench trial, the trial court entered a take-nothing judgment in favor of Royal American, and the First Court of Appeals of Texas affirmed that result in 2017. The record also reflects a pretrial settlement between Hensel Phelps and Arrowall for $110,000. In addition, Royal American recovered $4,500 on a counterclaim for unpaid repair work, plus prejudgment interest and attorney’s fees.
Why did roof flashing at a rooftop door threshold matter in this dispute?
The case turned on a causation question: whether flashing was present at the time of the storm and how the roof-to-door interface performed during heavy rainfall. The parties presented competing explanations tied to physical indicators at the threshold area, including impressions and residue described in testimony. These details mattered because the court’s fact findings depended on how that evidence supported one causation theory over another.
What does “responsible third party” mean in a Texas construction case like this?
In this case, the defendants sought to designate additional entities as responsible third parties, which is a procedural step that can affect how responsibility is allocated in the litigation. The motion named Houston Methodist Hospital, Broaddus & Associates, and WHR Architects, Inc. as proposed responsible third parties in the trial-court record. The filing positioned the dispute as involving multiple potential contributors to the conditions tied to the reported water intrusion.

What kinds of proof tend to matter most in Texas water intrusion claims?
The record shows a focus on site-specific conditions at the alleged entry point, including the roof membrane and the rooftop door threshold area. These cases often turn on what can be documented about the interface details and how those conditions relate to the timing of leaks. In practice, a forensic engineering approach refers to assembling and testing causation explanations against observable conditions and the sequence of construction changes reflected in the record.
What should attorneys take away from this Houston-area construction dispute?
The appellate outcome reflects how a bench trial can end with the trial court choosing between competing factual accounts when the record supports more than one interpretation. It also shows why claim framing and evidence organization matter when the dispute centers on a narrow set of roof-interface conditions. Keeping the narrative grounded in documented site conditions and a disciplined forensic engineering lens can help avoid overreach and keep causation arguments precise.
