invention relates to. .snap:in flashing adapted for use ona parapet wall ortwo-level roof.

While many types of flasliin g have,heretofore been devised, .many of them arounsatisfactory for -use where a flashing ,is desiredawhich, .canbe quickly;inserted into position or detached, and which ;,c ombines gpleasing architectural design with t economy of manufaeture and installation.

According to this v inv nt ior1,,such .a flashing ,is supplied by .pr'ovidingananchor sectionhavingafiat metal body portion arranged to ,fit between adjacent icourses got a Wall with two flanges depending therefrom,;gthis.anghor section.,cooperatinglwith @a skirt f flexible-metal, {the p -ed o hi h-fits be w en th s 1sss=a ba bent-over edge "engaging I an outwardly protruding .edge on the inner flange of the anchor member. Such a flashing is of pleasing architectural :appearance,,and;=,the lower edge of the skirt -is -for ,ced .into engagement with the adjacent wall surface by the 'flexibilityof the metal. Also, the skirt is readily detachable -wi-thout specialtools, jbut the construction is such that -it will not unintent-ipnal ly become :disengagedfrom the anchor section.

' The portion-ofthe anchor member can advantageously be formed from a double thickness of metal, thus providing for economy in manufacture of the entire anchor section from a single metal piece. The inner edge of the double thickness of metal can be readily turned up to simplify locking the anchor section into position and provide improved water sealing.

Accordingly, it is an object of the invention to provide an improved flashing which can be readily snapped into position or removed.

It is a further object to provide a flashing of attractive appearance which has a low cost of manufacture and in stallation.

Various other objects, advantages and features of the invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings in which:

Figure 1 is a perspective view of the flashing installed on a two-level roof;

Figure 2 is a vertical sectional view of the anchor section; and

Figure 3 is a vertical sectional view of the flashing skirt.

Referring now to the drawings in detail, a spandrel beam supports a plurality of courses 11 and 12 of a wall which, in the example shown, is formed from concrete blocks. This may be a parapet wall, or a vertical wall joining two horizontal sections of a split-level roof.

A horizontal roof section 13 extends to the spandrel beam 10, and boards 14 to fill up the space between the vertical edge of the roof and the spandrel beam. The joint between the vertical wall and horizontal roof is covered by a sheet 15 of fabric, tar paper, or like construction material which, in turn, is covered by a layer 16 of roofing material, such as tar containing gravel, asphalt or the like.

Where the edges 23, 26 'intersec t at an :acute angle and the edge"23' is stiffer-than the edge 26, removal of the skirt is facilitated.

The flashing can be constructed in relatively short pieces of standard length, using lap joints 30 between adjacent anchor sections and staggered lap joints 31 between adjacent skirt sections. This assures weather tightness and complete freedom for thermal expansion and contraction.

It will be evident that I have achieved the objects of the invention in providing flashing which terminates a built-up roof -at a wall juncture with an architecturally attractive weather proof design. Due to the shape of the parts, and the flexibility of the metal, frictional engagement holds the skirt firmly in position yet permits it to be readily removed for roof inspection, repair work, or new roof installation. Finally, all parts of the assembly can be readily fabricated on simple equipment available in all sheet metal shops, or it can equally well be made on mass production equipment at very low cost.

While the invention has been described in connection with a present, preferred embodiment thereof, it is to be understood that this description is illustrative only and is not intended to limit the invention.
