FIELD OF THE INVENTIONThe invention relates to roof drip edge and coverings for fascia.
DESCRIPTION OF THE RELATED ARTMany buildings include a plurality of upstanding walls covered by a roof. The roof is typically downward sloping and covered by a plurality of shingles. The section of the wall near the roof is often covered by a fascia strip for protection and also to allow installation of a gutter to collect water and other debris that rolls off of the roof.
A disadvantage of such roof constructions is that water often seeps between the gutter inner wall and the fascia strip, causing rot and deterioration of the fascia strip. Moreover, in some types of construction, water can seep between the fascia and the side wall of the building, causing even more extensive damage. Water can also seep in between the roof shingles and the roof boards, causing rot and deterioration of these structural elements.
In an attempt to ameliorate these problems, drip edges are sometimes installed. A simple drip edge may be a planar sheet of plastic or metal inserted between the shingles and the roof which extends out over the edge of the roof, at the same downward slope as the roof. In this way, water and other debris from the roof is directed away from the building. Commonly, the water and other debris are directed into a gutter.
Heretofore, roof drip edges have been formed of aluminum or galvanized steel, and generally come in ten-foot lengths. Due to their length and material composition, such drip edges and fascia coverings are difficult to handle and to install and are also easily dented or bent. Such dented or bent edges when installed can be unattractive and can form undesirable gaps, which allow water to work its way back up under the roofing shingles. Roof drip edges of rigid plastic material have also been recently used in order to eliminate the denting and bending which occurs in metal edges. However, plastic is subject to buckling and puckering with changes in temperature, particularly where the material is vinyl.
There is a need for a means to install vinyl drip edge and fascia coverings that exactly match the color and material of commonly installed vinyl siding. There is also a need to enable covering pieces for fascia and drip edge to accommodate expansion and contraction of the material due to temperature changes.
SUMMARY OF THE INVENTIONA drip edge according to the invention is adapted to be mounted to a roof, and comprises a frontal piece and a mounting flange. The mounting flange has a flexible portion, and the frontal piece is formed of a polymer having more rigidity than the flexible portion. Thus, the frontal piece will be able to move relative to a roof to which it is mounted so that it will not buckle with thermal changes. Preferably, the drip edge is formed of vinyl.
The frontal piece is typically rigid enough to resist deflection under force. Preferably, the frontal piece is colored. Also, the flexible portion has a color that contrasts with the color of the frontal piece. The mounting flange and/or the frontal piece can have a strengthening portion. Further, the flexible portion can be disposed between the frontal piece and the strengthening portion. The flexible portion is preferably disposed about 1 inch from the frontal piece. The strengthening portion will comprise at least one strengthening rib.
In another aspect, the drip edge can be part of a system that can also have a face that covers a portion of a fascia cover when the drip edge and fascia system is mounted to a structure. Also, preferably, the thickness of each of the fontal piece and the mounting flange is in a range of 0.8 to 1.3 mm, and both parts can be but need not be the same thickness. The fascia cover is preferably mountable to a fascia cover mounting bracket by snap fit.
In another aspect of the invention, the drip edge and fascia system can include a drip edge mounting bracket adapted to be mounted to a roof, where the drip edge is mountable to the drip edge mounting bracket in a manner to be independently moveable relative to the drip edge mounting bracket. In this way, the drip edge will not buckle with thermal changes.
A further aspect of the invention is found in an improvement in a structure having a roof and a fascia board with a drip edge mounted to the roof, and a fascia cover for covering the fascia board. The improvement lies in the drip edge comprising a frontal piece and a mounting flange. The mounting flange has a flexible portion, and the frontal piece is formed of a polymer having more rigidity than the flexible portion. Thus, the frontal piece will be able to move relative to the roof so that it will not buckle with thermal changes.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to
The drip edge and fascia system 10 comprises four separate components: a drip edge mounting bracket 16, a fascia cover mounting bracket 18, a drip edge 20, and a fascia cover 22. The drip edge mounting bracket 16 is best illustrated in
The drip edge mounting bracket 16 comprises a mounting flange 24 adapted to rest flat against the roof sheathing 12. The mounting flange 24 extends from a support channel 26. The support channel 26 comprises an upper arm 28, a bight section 30, and a lower arm 32. Preferably, the mounting flange 24 extends from the bight section 30 at the same angle as the pitch of the roof sheathing 12. The junction of the mounting flange 24 and the support channel 26 can be fixed, or it can be a flexible hinge to enable the drip edge mounting bracket 16 to be mounted to any roof, regardless of pitch. It will be understood that shingles (not shown) will be mounted to the roof over the sheathing 12 and the mounting flange 24.
One of the arms 28, 32 (here the lower arm 32) has a shoulder 34, which together with the bight section 30, defines a recess 35. Depending from the bight section 30 generally at a right angle to the support channel 26 is a guide channel 36, defined by a rearward arm 38 and a facing arm 40. The arms 38, 40 can be the same length as shown, or they can be different lengths to better accommodate receiving a fascia cover 22 as explained below. At least one end of the drip edge mounting bracket 16 has the support channel 26 and the guide channel 36 ending before the edge 37 of the mounting flange 24 and the rearward arm 38. Thus, an adjacent piece of drip edge mounting bracket 16 can overlap to inhibit migration of moisture between the drip edge mounting bracket and the roof sheathing 12 or fascia 14. If desired, a sealant can be interposed between overlapped portions.
The fascia cover mounting bracket 18 is best shown in
The fascia cover mounting bracket 18 comprises a mounting flange 42 extending at a right angle from a support flange 44. The mounting flange 42 is adapted to be nailed to the front of the fascia board 12. Depending from the support flange 44 is a support channel 46, defined by first and second arms 48, 50 spaced from each other. At a terminal end of each arm 48, 50, is an inwardly facing shoulder 52 which can be barbed as shown, or straight.
Both the drip edge mounting bracket 16 and the fascia cover mounting bracket 18 are preferably formed by extrusion. Because of the importance of inhibiting the intrusion of water from the roof to the sheathing beneath it or to the fascia, adjacent pieces of drip edge mounting bracket and the fascia cover mounting bracket are preferably overlapped.
The drip edge 20 is best illustrated in
The fascia cover 22 is best illustrated in
Preferably the drip edge 20 and the fascia cover 22 will be formed of the same material as the siding on the building to which it is installed. For example, the drip edge 20 and the fascia cover 22 can be formed of extruded vinyl with matching color. Similarly, they can be formed of aluminum if the house were to be sided with aluminum. When mounted, as shown in
A second embodiment of a drip edge and fascia system 100 according to the invention is shown in
The drip edge mounting bracket 102 comprises a mounting flange 110 adapted to rest flat against the roof sheathing 12. The mounting flange 110 extends from a support channel 112.

The mounting flange 302 comprises a flexible portion 315 extending away from the terminal edge 313, and a strengthening portion 316 extending from the flexible portion. The strengthening portion 316 includes one or more strengthening ribs 318 generally parallel to the strengthening rib 314. Two are shown in
Preferably, the mounting flange 302 and the frontal piece 304 are formed by co-extruding one or more polymers. The flexible portion 315 will have a formulation that, for example, includes softeners to enable it to be flexible, whereas the frontal piece 304 and the strengthening portion 316 will typically have a formulation that is more rigid. Preferably, the more rigid formulation will be similar to that used for window vinyl trim, and be made of more virgin compounds than is typically used for vinyl siding.
Color is immaterial to the strengthening portion 316 so the formulation needs no coloration for the strengthening portion. On the other hand, the frontal piece 304 will be visible, and therefore will preferably have coloration that matches or complements the coloring of the siding of the structure to which it is to be mounted. In order to better identify the flexible portion 315, it will preferably have a contrasting color such as black if the strengthening portion 316 and the frontal piece 304 are lighter. Thickness of both the mounting flange 302 and the frontal piece 304 will preferably be in a range of 0.8 to 1.3 mm. Ideally, both components will have the same thickness, although such is not critical to the invention.
