i need a way to seal this section of roof. ive used various silicone/putty/foam sealers to seal off nails, seams, etc. and theyve work mostly. but now the problem is the WHOLE section of roof. ive thought of using a clear liquid/spray sealer but reviews say they yellow/has a ugly cloudy look, even though the product says it doesnt yellow. example being flex seal that yellowed on me. maybe i can add another uv resistant product on top of the sealer? second option is lay a giant tarp over the whole roof. can anyone suggest a product that truly doesnt yellow due to sunlight over time or looky ugly, or any other solution
