Questions about Roof Sealant01 How Long Does Roof Sealant Typically Last Before Needing Reapplication?
We typically find that roof sealant lasts 10-15 years before needing reapplication, but we'll help you track its condition. Environmental factors and quality of installation can affect its longevity so regular inspections are important.
02 Can Roof Sealant Be Applied During Winter Months?
While we can apply roof sealant in winter, we don't recommend it. Most sealants need temperatures above 5°C to cure properly. For best results, we suggest scheduling applications during warmer, drier months.
03 Will Roof Sealant Change the Colour of My Roof Tiles?
No, we'll guarantee your roof sealant won't alter your tiles' original colour. Our high-quality sealants are designed to be clear and transparent, maintaining your roof's aesthetic while providing excellent protection. Call us at 044 505 67 69.
04 Is Roof Sealant Safe for Collecting Rainwater From My Roof?
We recommend waiting at least two weeks after applying roof sealant before collecting rainwater. After that, it's safe as the sealant fully cures and won't contaminate your water. Call us at 044 505 67 69 for details.
05 Can I Walk on My Roof After Sealant Application?
We recommend waiting at least 24-48 hours before walking on your sealed roof. If you must access it sooner, please contact us at 044 505 67 69 for specific guidance about your sealant type.
