Each specification in this section is eligible to receive a JM Peak Advantage Guarantee. Refer to Section lc on "Peak Advantage Guarantees" in the current JM Single Ply Roofing Systems Manual or contact a JM representative for additional information. Positive drainage of water off any roof membrane is neces- sary to prolong the service life of the system. JM, therefore, has the following policy: Drainage: Design and installation of the deck and /or mem- brane substrate must result in the roof draining freely, to outlets numerous enough and so located as to remove water promptly and completely within 48 hours.

This can lead to entrapped moisture, which can cause premature failure of the roofing system. Phase construction is unacceptable with any application. Good roofing practice dictates that no more roofing area be started than can be completed that day. This means that the finished membrane MUST be installed and seamed all in the same day. Water cutoffs must be installed at all exposed edges and removed when application is restarted. 3- 333 Scott County, MN y a i 1 1 ' + #g� , i 15750 N iT. €.k h 3 § x fl 4 'q Y . y i , rte ,, '" fi t, This drawing is neither a legally recorded map no a survey and is not Map Scale N intended to be used as one.

JM strongly recommends that the following guidelines be used when applying roofing systems in cold weather. 1. Let the membrane "relax" longer, and work on sunny days, if possible. 2. Keep all adhesives warm so that they can be applied in a thin, uniform film. 3. Keep all seam tapes, cements and sealants at room temperature until they are used, so they can be applied properly. 4. Allow adequate time for the solvents in the cements, and primers to "flash off" so that the laps will be properly fabricated. Check the "dryness" of the applied cements and primers carefully before joining the surfaces together. 5. Make sure that all frost and dew has evaporated before covering the roof deck and /or insulation with the mem- brane to prevent the entrapment of moisture within the finished roofing system. 3 -334 0 co 0 �� 0 m D' 0 Q- m o c v n� v m .� G H v m 'i 0 C N -IO 0— c jfl: P .- c 0 i m 7 .- 0 v o 3 m '3 o o 'c� ° n o_o 0o vm � _ ° v y o0 3 � u� a W N S @ VJ C 00 0 N m �"0 0 7c) o o_ c Q av 3 3 3 H - 3 y c kin c C./) 0. 6p '.
