JOINT DETAIL


10/06; Rev.7

The following subjects are applicable to the SDP 175metal standing seam roofs and should be reviewed inregard to the specific project.

GENERAL GUIDELINES

Wind uplift (negative) loads for roof slope, buildingheight, and shape must be reviewed as required by localbuilding code. Areas at roof eave, ridge, peak, and gableedges usually have about two times the negative load ofthe interior area. Supports are usually at 1/2 typical spac-ing in these areas.Diaphragm stiffness is not provided for by the SDP 175in the plane of the roof when attached directly to openpurlins or bar joists. Adequate bracing should be includedin the building structure.Bottom flanges of C and Z shaped open purlins and barjoists are in compression when subjected to high winduplift (negative) loads. Stabilization may be required.Panels must be fixed at eave, ridge or intermediate location. Purlins at fixed locations must be reinforced toprevent roll-over due to in-plane live load component andresistance thermal movement.Standard AISC alignment tolerances are not acceptablefor roof structures supporting standing seam roofs, espe-cially very low slopes. Industry standard for standingseam roofs is 1/4” from eave to ridge and is necessary toprevent binding of the sliding parts of the floating clipsduring thermal movement and to minimize oil canning.Compliance with UL 580 Class 90 Constructions limit SDP175 spans to 4’-0” maximum over open purlins or over rigid boardinsulation with bearing plates. Maximum clip spacing over plywooddeck is 3’-0”.Steel deck supporting rigid insulation will have concen-trated loads from panel clip locations, not uniform loads.requires a minimum of 22 ga. steel deck.Plywood sheathing must be a minimum 5/8” CD,required when UL580 Class 90 is specified.

SUBSTRUCTURE

SDP 175 panels are designed for application over openpurlins and blanket insulation.Purlins should be reinforced at fixing lines to prevent roll-over. Maximum purlin spacing is 4’-0” for UL580 Class 90.22 gage minimum deck can be used to support rigidisoboard insulation with Factory Mutual or UL label. Avapor retarder is required over the deck to prevent con-densation on the underside of the SDP 175 roof panels. 4”x 4” x 16 gage G90 steel bearing plates are used over theisoboard and under each panel clip. Maximum clip spac-ing is 4’-0” on center.Substructure must be on an even plane from eave toridge to avoid panel distortions. Maximum tolerance is1/4”.

SDP 175 panels may be installed over nominal 5/8” CD ply-wood deck with a 3” : 12” minimum slope. Maximum clipspacing for UL 580 Class 90 is 3’-0” on center.

CAUTION: SDP 175 panels are not designed to be work plat-forms. Avoid foot traffic on panels over open purlins and blanketinsulation by using a temporary deck or walkway.

INSULATION & THERMAL SPACERS

Thermal spacers are recommended as a means of increasingthe R-values of blanket insulation. (See R-value table below.)Thermal spacers prevent pillowing of the flat portion of thepanel when blanket insulation is compressed over purlins.Blanket insulation cannot be compressed by a snap seampanel such as SDP 175. Thermal spacers must be used withany thickness of blanket insulation.Nominal 1” x 3” wood spacers may be used. DO NOT USEPRESSURE-TREATED WOOD SPACERS. The chemicalsretained in the wood are potentially corrosive to purlins andclips.Rigid foam board must be listed by Underwriters Laboratory(UL), or a 15-minute fire barrier (such as gypsum board)must be used over the steel deck.

VAPOR BARRIERS

The vapor barrier must be specified on the warm side of blanket insulation and must be complete with all tears and holes repaired with vapor barrier tape to prevent condensation on the underside of the roof panels.A vapor barrier should be specified over steel deck used inconjunction with rigid foam board insulation.

THERMAL MOVEMENT

Maximum Roof Panel Length

Maximum length of roof panel is 40’-0” due to shippingrestrictions.One-piece clip offers unimpeded thermal movement anddoes not restrict length of multiple panel runs.

Panel Fixing Information

Standing seam roof panels must be fixed at eave, ridge,peak, hip, or an intermediate location for longer length pan-els. (Note structural requirement for reinforcing supports atfixing lines.)

Steel panels fixed at an intermediate location should haveadequate fasteners for the loading conditions. (The in-planefastener load will consist of the panel dead weight compo-nent and roof live load component in the plane of the roofslope. Note the structural requirement for reinforcing sup-ports at fixing lines.Multiple steel panel lengths up to 75'-0" may be fixed at eaveor ridge, peak or hip with a floating detail at the oppositeend. (Note structural requirement for reinforcing supports atfixing lines.)Multiple steel panel lengths up to 150'-0" may have a mid-run fixing line at an intermediate location up 75'-0" fromfloating eave or ridge, peak or hip. This may require the useof two or three adjacent purlins at the mid-point to be usedas fixing points depending on structural evaluation.Projects with multiple panel lengths over 150'-0" should besubmitted to for review.See graph (Fig. 1) for steel thermal movement for temperature changes from 50° F to 150° F.

RECEIVING

Upon arrival at the job site, the contractor is responsiblefor inspecting the shipment for damage and shortages. If damage or shortage is observed, a claim must be filedwith the carrier at once and the driver’s delivery docu-ments must be noted. If there is concealed damage orshortage, the carrier must be notified and a formal mate-rial inspection report requested of the carrier within 15days after delivery. Photographs and/or sketches of thedamaged components in their original packages will beneeded in submitting claims.

HANDLING

Metal roofing products must be carefully handled at alltimes to prevent damage to the surfaces, edges, andends. Exercise caution in handling bundles with fork lifttrucks or cranes. Use nylon band slings, minimum 4”wide, in a vertical position around the entire bundle orcrate, so as to safely balance the load and prevent com-ponents from sliding. Employ the use of a spreader bar tomaintain a vertical position of the slings. Do not lift bun-dles by the collars. Do not use cables to unload.

KEEP PANELS DRY

Any moisture that enters the bundle can affect the product finish. Remove any moisture from the bundles by breakingopen and allowing the individual building products to dry. Place tarpsor shrouds over the bundles in a manner that allows for good air cir-culation. Tightly covered or encapsulated bundles may create a“greenhouse effect” with temperatures greatly exceeding the sur-rounding air temperature. Combined with moisture, this conditioncan result in bacterial and chemical damage to the finish.

MINIMIZE STORAGE

Keep storage of roofing products to a minimum. Roofingproducts that are normally utilized within eight weeksfrom shipment can be placed at convenient locations tominimize handling during installation. Keep these bundlesand packages a minimum of 6” off the ground. Place ontimbers with one end elevated to permit drainage. Stackbundles no more than two high, with collars in verticalalignment. If collars do not align, place 2” x 6” woodplanking longitudinally between bundles. Store undershelter from sun and rain, while permitting good air circu-lation around and between bundles.

LONG TERM STORAGE

Roofing products that will be utilized in the work betweeneight weeks and 12 months after receipt must be storedand protected in a covered, dry location that providesgood air circulation around and between bundles, shield-ed from direct sunlight and free from the effects of mois-ture and other corrosive environments.

EXTENDED STORAGE

Storage of roofing products in excess of 12 months afterreceipt is not recommended.

SDP 175 is a handed (asymmetrical) self-interlocking roofpanel with concealed clips. Available in standard 16” or18” widths. Details are shown for left to right installationbut are reversible when the panels are turned 180°.Directional finish should not be used when panels areinstalled in two directions.Installation for simple rectangular roofs may start at thegable end with a partial or full panel and continue on to theopposite gable end. When there are hips at exterior cor-ners or valleys at interior corners, a “starter” panel may bemade by field-modifying a standard panel using a factory or field-cut adaptor to allow installation in both

directions as shown in Fig. 2. A starter panel may also beused at the middle of a very long roof so that the last cutpanels will be nearly equal.Standard factory panel length is 40’-0”. Lengths up to 60’-0” are possible on special orders with special provisionsfor transportation. When longer eave-to-ridge dimensionsare required, panels with factory flared upper ends for endlaps are available. A field-notched end lap detail may alsobe used.

End laps in adjoining panels must be offset byone support length to prevent build-up ofmaterial dimensions (Fig. 3).

SAFETY PRECAUTIONS

1. Comply with OSHA regulations.2. Metal surfaces are slippery when wet or covered with

dew or snow.3. Especially on slopes of 3” : 12” and higher, dry metal

surfaces are slippery.4. Protect electrical cords and equipment from shorting

with structure and panels.5. SDP 175 panels are not designed to be work platforms.

Avoid unnecessary foot traffic. Use pad, deck, walkway, etc.,with adequate temporary attachment.

ALIGNMENT

1. Check supporting roof structure for squareness,slope, and purlin locations.

2. Check for additional supports (shorter spans) ateave, ridge, gable edge, and corners.

3. Maximum out-of-plane tolerance from eave to ridgeor peak is 1/4”.

4. Check alignment of supports at hips and valleys.

PANEL INSTALLATION

1. See Material Handling (page 43).2. Check panels for proper location and perpendicular

alignment with eave.3. Fasteners in the flat area of the panel are applied

sequentially in the direction of installation to avoidbuckling and oil canning of the panel.

4. As a means of simplification, typical panel details donot show insulation or every sealant condition thatmay be required for weathertight installation. Typicalsealant applications are shown with the respectivedetails. Additional sealant details, when necessary,should be provided with the project shop drawings.

5. Immediately remove steel drill shavings from panel surfaces to prevent scratches and rust marks.

6. Protect finish surfaces from abrasion scuff marksand denting from tools and shoes.

7. Seal each panel at eave, valley, and end lap as it isbeing installed. Remove excess sealant with iso-propyl alcohol or xylene solvent. Do not use steelwool or abrasive pads.

8. Do not load panel crates or other heavy materials oninstalled panels.
