Unfortunately, the flashing on the southern exposed roof was deteriorating rapidly.
I used Eternbond tape to reseal the roofing to the stucco and to seal the top of the flashing to the siding after removing the old trim.
After sealing the top of the flashing, I screwed down the bottom where it was buckling and then resealed the seam with Loctite 375 a very low VOC construction adhesive.
I found it difficult to figure out which sealants and adhesives have the lowest VOC content. The Lowes store did not allow a search for low VOC adhesives and even their descriptions did not include the Material Safety Data Sheets that describe the VOC content. I was able to find a low cost low VOC adhesive by viewing the documents on the Loctite Product Site.
I concentrated my research on the Loctite brand because it was the only brand that Lowes sold that had low VOC content. The VOC content of 375 is < 0.1 %; < 2 g/l (calculated) which is very low. Low VOC’s are defined for paints and coatings as under 50 g/l. Construction adhesives can be up to 70 g/l. The LEED program requires the use of low VOC construction materials according to the California South Coast Air Quality Management District Rule #1168
