NRCA Tile Installer

It tests the whole tile roof assembly, not just laying tile. Expect questions and practical tasks on safety and fall protection, deck and underlayment selection, tile types and standards, flashing at walls, valleys, and penetrations, layout and fastening, hip and ridge details, low-slope transitions, repairs, and reading plans and code. The practical portion asks you to build a compliant assembly.

The exam combines multiple-choice and written questions with a performance-based practical assessment. In the practical, you install a tile roof assembly that includes typical details such as underlayment, flashing, and tile attachment. The written portion checks your knowledge of materials, code, and sequencing. The official body publishes the current format and any updates on its site.

It is demanding because it is hands-on and time-limited. You must demonstrate correct underlayment laps, proper flashing integration, consistent exposure, and code-compliant fastening without direct coaching. Candidates who have only installed field tile and rarely detail valleys or penetrations often struggle. Building a full mockup repeatedly before the exam is the best preparation.

Failures cluster at water-shedding details: backer flashing at sidewalls, valley treatment, pipe boot installation, and underlayment laps at transitions. Other common errors are overdriven or missing fasteners, incorrect fastener type for the deck, uneven course layout, and poor ridge or hip ventilation. Safety violations during the practical can also end the assessment early.

Start with safety and fall protection, because it frames everything else. Then study deck and underlayment, followed by tile materials and standards. Move to flashing and waterproofing, then layout and fastening, and finally eaves, rakes, hips, ridges, and valleys. Finish with steep- and low-slope applications, repair, and print reading and code. Practice each detail on a mockup as you go.

The official body publishes the current time limit and question count. These figures change, so confirm them on its website when you schedule. Do not rely on numbers from older candidates or training forums. Plan your study around the published domain weights rather than a question count.

Retake policies, waiting periods, and any fees are set by the official body and are published on its site. Check there for the current rules before you schedule. In the meantime, ask for your score report, identify the weakest domains, and rebuild your mockup practice around those details before attempting again.

The official body publishes the tool and material list and any restrictions. Review it carefully and practice with the same tools you will use. Bring appropriate personal protective equipment and be ready to work at height under observation. Confirm whether materials are supplied or you must provide them, and arrive early to set up.

The exam reflects the code edition and standards adopted by the certifying body at the time the exam was developed. Codes update on a cycle, so study the edition named in the current candidate handbook. If the handbook does not name an edition, ask the official body before you study.
