Hi We just had a bad windstorm that completely removed 2 whole shingles & 2 smaller shingles that had been shaped to fit along the sheet metal that joins 2 slops. I have reinstalled all the shingles but would like to now add an adhesive to the shingles since the adhesive strip along the bottom underside of the shingles has lost it's adhesive power. What would be the best adhesive to use for this job? thanks

Hi - Just checking to see if anyone has any other suggestions on what DIY options I have in repairing my roof. In the past, my roof had a problem with leaks and ponding water near the edge of the roof (see picture). That area is pretty flat with a slight slope that lead water to the drain. Last summer, I applied a very thick layer of Gaco silicone white coating (the white stuff in the picture). I dont think that Silicone coating was meant for repairing leaks but it did the job for the past year. I checked the roof this past week and the silicone coating still seem to be in very good shape. No cracks no fissure. I just dont know how long this will last. So I want to know what DIY options I have that is more of a longer term solution (3-5yrs) ? How does the pros handle a roof like this ? Is it an option if I lay a roll of aluminum sheet over the area ? Like using [URL="https://www.homedepot.com/p/Amerimax-Home-Products-14-in-x-50-ft-Aluminum-Valley-Flashing-68014/100015545"]this[/URL] If I cant find another solution, I',m thinking about applying another layer of the GACO Silicone coating just for maintenance and cover up a few spots that I missed. Is there any reasons why this solution is not advisable ? The product is quite expensive ($250 for 5gal.) and I dont think it is meant for making leaks repair, but at the same time it is the only easy solution I can come up with.
