Our next illustration shows using the full-width starter strip (below) when installing asphalt shingles that have a greater than 6" exposure. Note that it's installed after and atop the bottom edge starter strip along the eaves. Similarly here's GAF showing laying the starter strip along the rake edge (gable end edges). Nothing in GAF's tutorial suggests that extra adhesive is necessary in that location. With shingle nails placed this close to the roof eaves edge or rake edge (1 1/2 to 3" ), it's not likely that you need to add additional adhesive below the starter strip. It was this cellophane on the under-side of the starter strip and close to the roof edge, that prompted your question about using further adhesive. The nails are 1 1/2 to 3" above the bottom edge of the roof. Notice where the nails are placed on these special starter strips. Roofing underlayment and drip edge have of course been applied first. The half-width full length starter strip is nailed with a 1/4 to 1 1/4" overhang past the drip edge or roof edge. This position of the glue strip combined with nailing the starter strip as instructed is intended to give good resistance against wind up-lift at the roof edges in areas of high wind zones. When nailing on shingles that use an exposure of less than 6", this full-sized shingle is perforated at its center and is to be separated into two half-width pieces before installation.Īs you see in our next illustration (again from GAF) below, the yellow line is showing the proper position of the exposed glue strip near the starter strip's lower edge. Notice the position of the glue strips in two rows on the full 12" width (nominal, products may vary) starter strip, but don't be mis-led. Or consider using a peel-and-stick starter strip like the starter strips shown here, excerpted from from GAF's high wind resistance roofing starter strip tutorial that we cite in detail below. The cellophane strip is less than 1" in width.įor best adhesion of the shingle at the roof edges, I'd be sure that my adhesive contacted more of the shingle's lower edge, over the drip edge, than just the cellophane. However I agree that a more wind-resistant roof would be glued down right at the very lowest edge (and also at the gable end edges) - a detail I've seen specified in some hurricane zone roof instructions. When they're applied to the roof the cellophane won't be in a position to get in the way of the glue on the underside of that same shingle strip. The cellophane is, as you recognize, intended to keep the shingle strips from sticking together when in the bundle. Thanks for an interesting question that I'd not considered. This question was posted originally at CELLOPHANE STRIP ADHESIVE ADEQUACY in HIGH WIND AREASĪ reply to this question was (by my error) posted originally at ASPHALT SHINGLE CELLOPHANE STRIP REMOVAL as discussed by private email. (The glue was touching the cellophane protective strip and not the underside of the starter strip itself!) Under hurricane conditions on leading edge of roof, will this cellophane-protective strip peel away from the underside of the starter strip leaving the glue only sticking to the metal drip edge and not the underside of the starter strip itself? Is it ok using Liquid Nails Fuze it at this 3 inch area will where the glue is on the metal drip but the glue is also touching the cellophane-protective strip on the underside of the starter strip. Nails are 3 inches from the edge of the starter strip. Starter strips bottom side have a cellophane protective strip that touches the metal drip edge. Question: ok to use liquid nails to glue the shingles onto the drip edge? The illustration shows a GAF asphalt shingle starter strip - the GAF QuickStart®. Installing Asphalt Shingle Starter Strips We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. We answer the question: " Should we remove the cellophane strip over the shingle adhesive when nailing shingles or should it be left in place?" We cite authoritative research from industry experts as well as from shingle manufacturers themselves to give a definitive answer to the asphalt shingle release strip removal question: leave it in place. We explain the purpose of this cellophane strip. This article describes the cellophane strips found between individual asphalt roof shingles - atop the glue strip.
