IntroductionThe instructions and drawings included here are intended only as a guide for the installation of DECRARoofing Systems’ Villa Tile profile. The materials and methods specified help maintain the overall integrity ofthe roofing system. These instructions are not intended to address all aspects of roofing installation; a qualityinstallation is ultimately dependent upon the workmanship of the roofing contractor. Information regardingalternative situations not covered in these instructions can be obtained by contacting DECRA Roofing Systems.SafetyAdhere to recommended safe roofing practices. Wear appropriate clothing and use safety equipment, suchas protective eyewear. Light, soft-soled shoes are recommended. Use proper tools and keep the roof clear ofdebris as you work.ToolsDECRA panels and components are best cut with tin/aviation snips, a steel roof panel cutter shear, or apower saw with circular blade designed for use with metal roofing – also known as a ‘cool cut’ blade.Abrasive concrete/metal cutting blades in a power saw or high-rpm angle grinder can generate high frictionheat at the cut edge. This will reduce anti-corrosion zinc/aluminum alloy coating effectiveness to “heal” thecut edge, exposing premature corrosion. In all cases, wear eye protection!Estimating SheetThe DECRA Villa Tile Estimating Sheet is available at DECRA.com.Codes & RequirementsRefer to local codes and/or ICC Reports. A link to DECRA ICC reports is available at DECRA.com.Roof SlopeInstall of roof slopes of at least 3:12. Roof slopes less than 3:12 are considered decorative and panels must beapplied over a roof system complying with local codes.UnderlaymentOne Layer of Underlayment is required before installing ALL DECRA products in both New Constructionand Reroofing applications.Underlayment shall comply with ASTM D 226, Type I or Type II, ASTM D 4869, Type I or Type II or ASTMD 1970. Check local code requirements as ice and water shield and additional requirements may apply.Deck PreparationThe deck must be level and square for proper installation. If it is not, shim to make any adjustments. It isrequired that a layer of underlayment be used before applying the DECRA Villa Tile panels.New Construction: Prepare roof deck to meet local building codes.Re-Roof Tear-off (Skip/Spaced Sheathing) or Over Asphalt Shingle: If tearing off old roof, clean andprepare deck to meet local building codes.Panels may be installed over existing asphalt shingles or applied over existing spaced sheathing provided thespace between the boards is filled as necessary to provide a base for fastening.If installed over existing asphalt shingles, cut shingles back from the eaves and rake/gable edgesapproximately 8”. Remove existing hip and ridge material. In situations where code allows reroofing over 2layers of asphalt shingles, follow the local code.05/21 DECRA.comGeneral Installation - DECRA Villa Tile3

FastenersScrews: Use a minimum of at least 4 corrosion resistant screws minimum #9 Hex (1/4” hex head) x1-1/2” long. Use fasteners of sufficient length to penetrate through the sheathing (deck) by at least 1/2”.Recommended length is 1-1/2” long. For High Wind details, see website.Venting PreparationIf using DECRA Ridge Vent material, prepare the deck for ridge venting (without center beam) by cuttingboth sides of the plywood 3/4” from the center of the ridge to expose attice space, or as required by localcodes. Refer to Venting section or DECRA Ridge Venting wrapper for additional installation details. IfDECRA Villa Tile panel vents will be used, See Panel Installation - Installing Panel Vents and Venting.Measuring and Cutting PanelsMeasuring: Measurements are made on the roof, however, the panels are normally marked and cut on theground. Panels may be cut with a table saw or circular saw with concrete or metal cutting blade or tin snips.If the panels are cut on the roof, all residue and shavings must be completely removed.Panels: The DECRA panels are formed from corrosion resistant aluminum-zinc alloy coated steel witha protective coating of ceramic coated stone granules that provide an attractive appearance. The Tile Hip& Ridge, End Cap, both Bird Stops and Flat Sheet are produced in a similar manner. The Villa Underpan,DECRA Channel, and Villa Valley are also produced in the same manner, but are not stone coated.DECRA Villa Tile PanelPre-PunchedFastening TabsPansFactoryEdgeBack FlangeOverlap Area(Shaded)NoseFactoryEdgeOverlap Area(Shaded)Installed Exposure: 14-1/2” x 39-1/2”Panels per Square: 25.2Installed Weight: 160 lbs./squareVilla panels are not designed to be installed over irregular surfaces.Do not rack panels.Avoid creating a pattern with the light or dark color patches unless it is aesthetically pleasing.Do not create a pattern.Do not use LEAD or COPPER with this steel roofing systembecause they are dissimilar metals and are not compatible.4General Installation - DECRA Villa TileDECRA.com 05/21

Preparation for Panel Installation2 x 2s at Gables, Hips and Ridges: Over a prepareddeck, position two stacked 2 x 2s flush along the rake/gables, up the center of the hips and along the ridges.Additional lumber (1 x 2 or 2 x 2) may be needed ontop of the two 2 x 2s at the hips and the ridges to allowfor proper attachment of the Tile Hip & Ridge Piece,determined by roof pitch.Pre-paint vertical/exposed portion of DECRAChannel as needed prior to installing panels.2 x 2sStackedDECRA Channel: Install DECRA Channel at rake/gable (see diagram left), roof-to-wall and alongboth sides of the two 2 x 2s at the hip (see diagram right). Overlap channel pieces 6”. Fasten to deck bypositioning fasteners just inside the last rib. Apply roof sealant to the fasteners. DECRA Channel is brokenunder 90 degrees to fit at the hip; hand bending will be required to fit tight along the 2 x 2s or at the gable.Make sure the DECRA Channel extends beyond the fascia at least 1” or onto a lower roof area. DECRAChannel extension over facia may be bent at a downward angle.

Place padding between jack and panel to avoid scuffing.One 1 x 4 will be attached under the top of the roof jack and intothe roof deck above the last course of panels. The second 1 x 4will be placed in the pan of the panel of the last installed courseto support roof jack. Install the next course of panels by notchingthe nose of the panel at the jack location and folding it up (do notcompletely remove the piece). When removing the roof jack, foldthe nose of the panel back into place and finish using a roofinggrade sealant/adhesive and a Touch-Up Kit.1x41x4High WindIn areas prone to hurricanes and high winds, installation must meet local standards and codes.Freeze / ThawIce and water shield is recommended in all areas susceptible to freeze/thaw conditions.Foot TrafficAvoid walking on side laps. Foot traffic on Villa Tile Panels should be kept to the tile pans or low points, noton the high points. See walking instructions at DECRA.com.SealantsA roofing grade sealant/adhesive should be used with this roofing system. Where possible, the sealant shouldbe covered by the roofing system or with matching stone granules. Sealant should not be used torefinish damaged panel surfaces. Touch-Up Kits are available in colors matching the various stone coatedpanel finishes.Cleaning & RepairsAfter installation is complete, be sure to clean all debris off of the roof, especially any metal shavings.In cases where it is necessary to touch up or repair a panel, DECRA Touch-Up Kits are availablein all of the colors matching the stone coated panel finishes.
