alternatively referring to fig3 if neither the use of slots 332 or 432 or the bottom edge 344 of the lowest rows of apertures 326 and 426 extend below plane 442 to allow water to drain into gutter 302 another embodiment of this invention is shown an inherent opening 771 is formed between the trough 330 and 430 of covers 300 and 400 the adjacent edges of 334 and 434 of both covers form flaps from the overlapping of the troughs 330 and 430 which because the angles of the front walls 334 and 434 are different and inherent space 771 is formed between them which serves to deliver any water in trough 430 into the gutter 302 during rain fall conditions temperatures outside the gutter 302 and covers 300 and 400 are cooler than temperatures inside the gutter 302 and cover 300 and 400 this difference in temperatures creates a minor pressure difference such that the pressure inside the gutter 302 and covers 300 and 400 is lower pressure than the pressures outside the gutter 302 and covers 300 and 400 the combination of this pressure differential and surface adhesion causes any water in the trough to be drawn through the inherent opening 771 the opening is sufficiently small enough to keep debris from entering the gutter 302 fig4 depicts a third embodiment of the present invention fig4 depicts a cover 500 installed under the roofing shingles 504 of a building 506 typically the building 506.
