NRCA Tile Installer study guide
NRCA Tile Installer · Work through your exam, one topic at a time.
The NRCA Tile Installer credential is a professional certification for roofers who install clay, concrete, and other tile roof assemblies. It is intended for experienced installers, foremen, and supervisors who want to demonstrate competence in code-compliant, watertight tile roofing. The NRCA Tile Installer study guide has 9 sections and about 3,143 words.
01Safety, Fall Protection, and Jobsites
The exam checks whether you can keep a tile crew legal and alive on steep roofs: OSHA fall-protection triggers, acceptable systems, access rules, and the jobsite hazards unique to heavy clay and concrete tile. Under 29 CFR 1926 Subpart M, a worker exposed to a fall of 6 ft or more to a lower level needs guardrails, safety nets, or personal fall arrest.
411 words, about 2 min02Roof Deck, Underlayment, and Substrate Preparation
Tile is one of the heaviest roof coverings, so the sheathing must be sound, flat, and thick enough for the span. Code sets a minimum wood structural panel thickness for tile, and many manufacturers plus NRCA call for 3/4 in.
358 words, about 2 min03Tile Materials, Types, and Standards
Clay roof tile is specified under ASTM C1167, which grades tile by weathering resistance; Grade 1 is the severe-weathering grade used in heavy freeze-thaw climates. Concrete roof tile falls under ASTM C1492.
333 words, about 2 min04Flashings, Penetrations, and Waterproofing Details
Step flashing is the backbone of tile sidewall details: each piece turns at least 4 in. up the wall and 4 in.
367 words, about 2 min05Tile Layout, Attachment, and Fastening
Tile length equals exposure plus headlap, and the headlap must meet the manufacturer's minimum, commonly about 3 in. Establish a level starter course at the eave, snap horizontal chalk lines at the gauge, and snap vertical lines to control coursing.
317 words, about 2 min06Eaves, Rakes, Hips, Ridges, and Valleys
At eaves, an eave closure or bird stop closes the gap under the first course, the drip edge sheds water into the gutter, and the overhang is kept within the manufacturer's limit, commonly 1 to 2 in. Rake edges use rake tile, barge boards, or a trim piece fastened mechanically to the barge or fascia, not held by mortar alone.
350 words, about 2 min07Steep-Slope and Low-Slope Tile Applications
Tile is a steep-slope covering. Under the International Residential Code, clay and concrete tile is limited to slopes of 2.5:12 and steeper; anything flatter requires a different roof system or a documented manufacturer approval.
344 words, about 2 min08Repair, Restoration, and Maintenance
Water travels, so a ceiling stain rarely sits under the leak. Start uphill and work down: check penetrations, sidewall and chimney flashings, valleys, and ridge details before blaming field tile.
332 words, about 2 min09Print Reading, Estimating, and Code Compliance
Start with the title block, scale, and north arrow, then read the roof plan for slope notation, because 6:12 means 6 in. Plan dimensions give plan area, not roof area.
