Answer: 
Depends on the substrate. If it's metal, then yes. It it's EPDM rubber, then no. The safest bet would be to use our Henry 885 Tropi-Cool 100% Silicone Seam & Repair Roof Sealant or Henry 887 Tropi-Cool 100% Silicone Roof Coating. These work on most substrates and are great for RVs. For more info, check out www.henry.com or contact product support at 800-486-1278.

I have a flat rubber roof and lately I have been having trouble with leaks. I went up to the roof to see if I could find any holes or cracks and did not see any. I was hoping this would help me stop the leaking, will it? And if not, can you please make a suggestion! Thank you!

I am re-shingling a cottage in a New England coastal region with very high marine winds. In addition to nailing the shingles, I plan to cement all the tabs down. Is this the best Henry product for that purpose? Thanks.
