Coastal climate and exposure detailing: principles and terminology
Where coastal salt comes from and how far it matters, why the side facing the sea and the sheltered undersides behave as they do, the Texas windstorm inspection frame, and the safety boundary for roof and edge inspection.
You will be able to: Explain how salt spray reaches and corrodes metal near a coast, which building surfaces suffer most, how the Texas windstorm program frames coastal work, and who decides what on a coastal project.

Coastal climate and exposure detailing: materials, standards and design constraints
Texas code editions from April 2026, what Exposure D does to wind pressure, what FEMA and IBHS say about fasteners, zinc and stainless, why metals in contact matter by the sea, and how warranty documents define coastal for themselves.
You will be able to: Identify the code editions, wind exposure terms, fastener and metal guidance, and warranty distances that govern coastal sheet-metal work, and say whose document each one is.

Coastal climate and exposure detailing: methods and worked application
An eight-step coastal exposure review, a worked example of three assumed sites tested against three documents, a worked wind exposure example, and how to choose fasteners, plan inspection and keep the evidence.
You will be able to: Run a documented coastal exposure review in eight steps, testing assumed sites against the documents that govern each product and recording assumptions, units and evidence.

Coastal climate and exposure detailing: defects, verification and case study
How to read a coastal defect, the common ones (rust at galvanized fasteners, sheltered undersides, copper run-off, edge lift), the safety boundary for inspection at height, a yearly inspection card, and a constructed case study.
You will be able to: Diagnose a plausible coastal corrosion defect from symptom to mechanism to evidence, explain corrective options as the designer's choice, and run the method on a constructed project.

Practical task
Produce a documented coastal exposure review for one assumed project near the Texas coast: set out the site, the rules and the exposure inputs, list every metal and its governing document, test the distances, and write one defect analysis.
Hand in
- A decision rationale: the documents that govern each metal, coating and fastener (maker, form or data sheet, and date), each named, and the distances and exclusions you checked
- A marked-up sketch of one edge or eave showing the ocean-facing side, the rain-washed faces and the sheltered undersides
- An assumptions sheet with units: distance from the closest building feature to each shoreline type, the shoreline type, mean roof height and the exposure the designer declared, each labelled measured, from the designer or assumed
- A yearly inspection checklist for the building and a record sheet that holds photographs, dates and the packaging, data sheet or invoice for each fastener
- A defect analysis for one plausible coastal defect: symptom, mechanism, evidence and options, with the decision left to the designer of record
Rubric
| Criterion | Meets the standard when |
|---|---|
| Governing documents | Every metal, coating and fastener names its maker, form and date, and the distance and exclusions in that form were checked rather than assumed. |
| Whose number it is | Every value is labelled as FEMA, IBHS, TDI, a maker, AFS or assumed, and nothing is presented as a code requirement that is guidance. |
| Exposure and wind | Risk category, wind speed and exposure are shown as coming from the designer of record, and no value is invented. |
| Sheltered and exposed | The sketch marks the ocean-facing side and separates rain-washed faces from sheltered undersides, with a reason for each. |
| Defect analysis | The analysis links symptom to mechanism to evidence, and leaves the corrective choice to the designer of record. |
| Safety | The inspection plan names fall protection before work at height and cites the 6 foot trigger in 29 CFR 1926.501. |
