BXI Flashing Roll Tape Membrane, 2 inches X 32 Feet Thick Waterproof Patch Seal Tape, Self-Adhesive SBS Modified Rubberized Asphalt, Deck Seam Joist Leak Sealant for Roof Window Gutter Repair Outdoor

I used this 6” flashing on the roof of my insulated alumawood patio cover seams. It was easy to apply and worked out perfectly. The old flashing was 4” so I ordered the 6” so I would have a 2” coverage on either side. The reason I replaced it was the old flashing was starting to curl in a few places so I cut out the curl to make it as smooth as Possible. The patio cover is 15 years old and I’m sure this product should last as long.It looks like the same as the old flashing.

#1 Top quality with extreme adhesion

The width & length of the material is perfect allowing me to run the length of the dormer in one piece therefore no seams. Adhesive is very sticky and sealed over the original aluminum flashing pieces that were leaking. No more leaks.

After a year of use I noticed some shrinkage in the sun on roof of rv

Flashing along wall was really beat up (lots of patched holes, edge no longer sealed to roof, etc.) as it was not replaced when I had my roof reshingled. In hindsight I should have had that done at the time; however, doing so would have been a big job. I was getting ready to get out the caulking gun, several tubes of roofing seal, and a gallon of rubberized roofing cement when I came across FLASHBAND which looked like a superior solution. Flashing was 5" wide so I overlapped two courses of the 4" FLASHBAND (about 50'). I installed the lower course first which extended an inch or more over the shingles below the flashing edge and then the upper course overlapping the lower course by an inch per the directions. I had already removed all the old cement patches (big bumps) and screwed down the flashing edge with 1 1/2" deck screws so the surface would be clean and smooth. The FLASHBAND went down very easily and adhered really well to the shingles and flashing. Time will tell how well it holds up. The 4 stars for installation ease was due to the thin foil backing which would frequently separate while unrolling the FLASHBAND - minor annoyance. Two of the 4 rolls I purchased had sturdier clear cellophane backing which did not separate at all so it looks like the manufacturer already rectified that problem. I plan on spray painting it black later. Only beef is that I was unable to get large width FLASHBAND from Amazon. Several widths are manufactured but only 4" is available on Amazon.

This is a really nice product, keep in mind that when applied you will want to apply quite a bit of pressure while putting it down on your roof. Also, go slow as you apply pressure- only touching the exposed sticky side of the tar like tape to the surface as you are (in a sense) molding it to your uneven surfaces. If you lightly apply it first and then go back over it, you’ll have air gaps created in other areas as you apply pressure (the piece of tape will pull up elsewhere while you push down in another spot). My best advice, go slow. It’s a great product.
