1According to NRCA guidelines, which underlayment system is standard for most clay and concrete tile roofs in low-to-moderate wind zones?

A.Two-ply hot-mopped or self-adhering underlayment (ASTM D1970)

B.Single layer of 15-lb felt stapled directly to the deck

C.30-lb felt installed with cap nails alone

D.Synthetic underlayment only, no secondary layer required

Explanation: NRCA's Roofing Manual: Steep-Slope and the FRSA/TRI installation manual specify a 2-ply hot-mopped system or a self-adhering underlayment meeting ASTM D1970 as the standard for tile roofs. These systems provide redundant waterproofing and are critical under the heavy, rigid tile that prevents simple leak inspection.

2ASTM D1970 governs which type of underlayment used in tile roofing?

A.Self-adhering polymer-modified bitumen underlayment (ice-and-water type)

B.Organic felt base sheets impregnated with asphalt

C.Fiberglass-reinforced 30-lb dry felt

D.Perforated felt underlayment used under composition shingles

Explanation: ASTM D1970 is the standard specification for self-adhering polymer-modified bituminous sheet materials used as steep-slope roofing underlayment. Under tile, it functions as the primary waterproofing membrane in a two-ply system or as a full self-adhering underlayment approach.

3A tile installer must choose between battens and direct-to-deck installation. Which statement about battens is correct?

A.Battens elevate tiles off the deck to promote drainage and air circulation beneath the tile

B.Battens are used only on slopes greater than 12:12 to prevent tile slippage

C.Battens eliminate the need for underlayment on concrete tile roofs

D.Battens are required only for mortar-set installations, not mechanically fastened tile

Explanation: Wood battens installed horizontally over the underlayment create a drainage plane that allows water infiltrating beneath the tiles to escape rather than ponding on the deck surface. They also allow air circulation, reducing thermal stress on the deck. Battens are used on both low- and steep-slope tile applications and do not replace underlayment.

4Which tile attachment method is the primary mechanical fastening approach for most concrete and clay tile installations?

A.Two nails per tile driven through the nail holes provided by the manufacturer

B.Foam adhesive applied at three points on the underside of each tile

C.Mortar dabs at the head and tail of every course

D.Metal clips installed at the head of each tile only

Explanation: Standard practice per the NRCA Roofing Manual and FRSA/TRI manual is to nail each tile using the manufacturer-provided nail holes, typically two nails per tile for field tiles. The nail penetrates the batten or deck directly. Nailing is the baseline attachment method, with supplemental foam, clips, or mortar added in high-wind areas.

5In hurricane-exposure zones, the FRSA/TRI manual and Florida Building Code require enhanced wind-uplift attachment for tile. Which combination is most commonly specified?

A.One nail plus foam adhesive applied per the tested system's approval

B.Mortar bedding alone without mechanical fasteners

C.Stainless steel clips with no underlayment modification

D.Two nails only, with no supplemental adhesive or clip

Explanation: High-velocity hurricane zones (HVHZ) require tested systems — typically one nail per tile combined with polyurethane foam adhesive applied in a specific pattern (one or two 4–6 inch beads) that together achieve the required wind uplift resistance per SSTD 11 or NOA testing. The foam-and-nail combination is the dominant approved system in Florida HVHZ markets.

6What is the primary purpose of polyurethane foam adhesive when used in tile roofing attachment systems?

A.To supplement mechanical fasteners in achieving required wind-uplift resistance

B.To replace the need for underlayment on low-slope tile applications

C.To eliminate ponding water under S-tiles in valley areas

D.To bond mortar at ridge caps without the need for nailing

Explanation: Two-component polyurethane foam adhesive is applied to the underside of the tile before placement and bonds to the batten or deck/underlayment surface. In tested assembly configurations, this significantly increases wind-uplift resistance compared to nails alone and is required in many coastal and HVHZ markets.

7Concrete roof tiles typically impose a dead load on the structural framing of approximately:

A.9 to 12 pounds per square foot (psf)

B.3 to 5 psf

C.15 to 20 psf

D.1 to 2 psf

Explanation: Concrete roof tiles weigh approximately 9–12 psf depending on tile profile and manufacturer. This is significantly heavier than asphalt shingles (~2–3 psf) and requires verification of the roof structure's load capacity before installation. The structural engineer of record must confirm the framing can support tile loads.

8Clay roof tiles typically impose a dead load on the structural framing of approximately:

A.7 to 10 pounds per square foot (psf)

B.9 to 12 psf

C.2 to 4 psf

D.12 to 16 psf

Explanation: Clay tiles are generally lighter than concrete tiles, typically ranging from 7–10 psf. While lighter than concrete, clay tile still imposes a substantial dead load compared to asphalt shingles and requires structural review before retrofit installations on existing structures.

9An eave flashing for a tile roof must be designed primarily to:

A.Direct water that travels under the tile at the eave back onto the roof or into the gutter

B.Increase the wind-uplift resistance at the bottom course of tile

C.Serve as the sole waterproofing membrane at the eave

D.Prevent ice dam formation in all climate zones

Explanation: The eave or 'bird stop' area of a tile roof requires flashing or a birdstop closure that channels wind-driven or gravity-fed water that has traveled beneath the tile back out to the gutter or roof edge. Eave flashing works with the underlayment system; it does not replace underlayment as the sole waterproofing layer.

10A 'birdstop' in tile roofing refers to:

A.A closure piece at the eave that seals the open space at the bottom of the first tile course while allowing water drainage

B.A metal flashing installed at the ridge to prevent bird nesting only

C.A type of foam adhesive applied at the eave to supplement nailing

D.A code-required pest barrier installed at gable rake edges

Explanation: A birdstop (also called an eave closure) is an interlocking or foam/metal closure installed at the eave of a tile roof. It fills the gap at the bottom of the first tile course created by the tile's profile, preventing birds and pests from entering while still allowing water that drains behind the tile to exit. On S-tile and barrel tile, this gap can be significant.

NRCA Tile Installer Study Tips from Top Performers

1Know the two underlayment systems: two-ply hot-mopped (ASTM D312 Type III/IV asphalt) and ASTM D1970 self-adhering — both require correct lap dimensions (2-inch side, 4-inch end for hot-mopped)

2Memorize minimum slopes: 2.5:12 for flat/interlocking tile, 4:12 for two-piece barrel (mission) tile

3Tile dead loads: concrete 9–12 psf, clay 7–10 psf — always evaluate structural capacity before re-roofing

4HVHZ: all tile products and attachment systems must have a current Florida NOA; the bead pattern for foam adhesive must match the tested NOA configuration exactly

5OSHA 29 CFR 1926.1153 requires wet cutting (engineering control) for all tile cutting to suppress crystalline silica dust — dry cutting is prohibited

6Weatherblock foam closures are preferred over mortar for ridge/hip caps in seismic zones because they accommodate differential movement without cracking

Frequently Asked Questions

What does the NRCA ProCertified Tile Installer exam cover?

The exam covers the full scope of clay and concrete roof tile installation per the NRCA Roofing Manual: Steep-Slope and the FRSA/TRI Concrete & Clay Roof Tile Installation Manual. Topics include two-ply underlayment systems (hot-mopped and ASTM D1970 self-adhering), batten and direct-to-deck installation, tile attachment methods (nails, clips, foam adhesive), HVHZ wind-uplift requirements and NOA-tested systems, flashings (eave, rake, valley, step, counter, chimney), ridge and hip details (mortar and weatherblock), tile dead loads, anti-ponding details, birdstop closures, wet-saw cutting, walkability techniques, and OSHA silica and fall protection requirements.

What is the FRSA/TRI manual and why is it important?

The FRSA/TRI Concrete & Clay Roof Tile Installation Manual is co-published by the Florida Roofing, Sheet Metal and Air Conditioning Contractors Association and the Tile Roofing Institute. It is the primary installation standard for clay and concrete tile roofs, referenced by the International Building Code and Florida Building Code. It specifies underlayment systems, minimum slopes, attachment methods, flashing details, and HVHZ wind-uplift requirements. NRCA's tile installer exam is based on this manual and the NRCA Roofing Manual: Steep-Slope.

What is the minimum slope for tile installation?

Per FRSA/TRI, the minimum slope for flat and interlocking tile (S-tile, flat concrete tile) with a standard two-ply underlayment system is 2.5:12. For two-piece barrel (mission) tile, the minimum is higher at 4:12 due to the open profile's greater vulnerability to wind-driven rain. Below these minimums, additional waterproofing measures or alternative roofing materials are required.

What are the tile dead load requirements I need to know?

Concrete roof tile typically weighs 9–12 psf; clay roof tile weighs approximately 7–10 psf. Both are 3–6 times heavier than asphalt shingles (2–3 psf). Before re-roofing a structure with tile, a structural engineer must verify the existing roof framing can support the increased dead load. This is the first critical evaluation step before any tile re-roof project.

How is tile attached in hurricane zones (HVHZ)?

In Florida's High-Velocity Hurricane Zone (Miami-Dade and Broward counties), tile products and attachment systems must have a current Notice of Acceptance (NOA) from Miami-Dade County. The dominant tested system is one nail per tile combined with polyurethane foam adhesive applied in the specific bead pattern described in the NOA. Deviating from the NOA-tested pattern invalidates the approval. All products must be approved before installation begins.

What is a birdstop and where is it used?

A birdstop (also called an eave closure or profile filler) is a closure piece installed at the eave of a tile roof. It fills the open void created by the tile profile at the bottom of the first course, preventing birds, bats, and insects from nesting beneath the tile while still allowing drainage of water that travels behind the tile. Different tile profiles (barrel, S-tile, flat) require different birdstop shapes, and manufacturer-specific closures are often available.
