A roof ridge vent for covering an opening at a peak of a roof. The roof ridge vent includes a top panel portion having first and second opposed lateral edges and having first and second opposed ends. The roof ridge vent includes a plurality of support members depending downwardly from the underside of the top panel portion, and the roof ridge vent also includes first and second lateral ventilation louvers respectively disposed adjacent the first and second opposed lateral edges. The vent also has first and second undulating sidewalls respectively downwardly depending from, and adjacent to, the first and second opposed lateral edges, with each of the sidewalls being non-planar and undulating along its said respective lateral edge such that the roof ridge vent may be flexingly rolled lengthwise into a spiral roll prior to installation and further may be unrolled lengthwise during installation over the peak of a roof. A method is also described for weldedly bonding sections of roof ridge vent by heating adjacent ends of successive sections above the melting point of the thermoplastic material, then abutting the heated ends, and then allowing the ends to cool below the melting point of the thermoplastic material. A variety of additional ways are shown for joining successive sections of roof ridge vent so as to create an elongated rollable length of roof ridge vent. |

DETAILED DESCRIPTION OF THE INVENTION Referring to FIGS.
1-5, the shingle-over roof ridge vent 20 of the present invention, a so-called "shingle-over roof ridge vent" is seen to comprise a top panel portion 22 having first 24 and second 26 opposed lateral edges and having first 28 and second 30 opposed ends.
The top panel portion 22 has an underside 32 and a topside 34 and further has a midsection 36 substantially parallel to the first and second lateral edges 24 and 26, with midsection 36 preferably being flexible along a centrally longitudinal region 38 substantially parallel to first and second lateral edges 24 and 26 so that roof ridge vent 20 may longitudinally flex along midsection 36 so as to rest across the peak or apex 40 of a roof 42 and thereby accommodate varying roof pitches.
The roof ridge vent 20 is preferably constructed of a plurality of five foot (1.
52 meters) long and 14.
5 inches (36.
8 cm.
) wide injection-molded flexible and substantially identical plastic sections made of a thermoplastic material, such as a polypropylene copolymer with an elastomeric additive, preferably a so-called thermoplastic olefin ("TPO") material, with the sections being subsequently welded end-to-end in a manner hereinafter described so as to form a continuous and rollable length of roof ridge vent, typically 20 feet in length (6.
1 meters) and 14.
5 inches (36.
8 cm.
) wide per roll, with the typical thickness of top panel portion 22 being approximately 0.
05 inches (1.
27 mm.
).
Roof ridge vent 20 is adapted for covering a well-known opening 44 at the peak or apex 40 of roof 42.
In a manner well-known to those skilled in the art, roof 42 is formed with a longitudinal main beam 46 supported by a plurality of transverse cross beams such as cross beams 48, and cross beams 48 support well-known plywood decking panels 50 thereover, with decking panels 50 being covered by a plurality of shingles 52 and roofing paper (not shown) affixed to decking panels 50 as by nails or the like, in a manner well-known to those skilled in the art
