Roof sealant is one of the fastest fixes, but also one of those things that can go wrong so easily. Most failed sealant jobs can be traced back to avoidable mistakes in prep, timing, or application – not to the product itself.
Common mistakes when sealing the roof (and tips to avoid them)
1) Seal without actually finding the real leak
Water will often travel before it manifests internally. Only root at the spot – sealing another part means the leak will resume. Start from the source and work outwards, looking at neighbouring joints, edges and flashings. For Roof sealant, contact www.ct1.com/product-applications/ct1-the-ultimate-roof-sealant
2) Putting down sealant over a wet, dirty or dusty surface
Sealant needs a clean bond. It will peel off, either due to moss or grit, or it may be moisture that unsticks it. Scrub off loose debris, sweep and dry completely.
3) Never apply a sealant that is not compatible with the roof
Compatibility requirements can vary with the different materials such as felt, EPDM rubber, GRP/fibreglass, metal and tiles. You should always select a sealant formulated to suit your rooftop coverings (and if needed, follow primer instructions).
4) Sealing over loose or failing materials
If the membrane is blistered, lifting, or cracked over a bigger expanse as well, sealant will commonly be merely a band-aid. You will be resealing again soon if you do not first fix the underlying issue.
5) Too thin (or also thick)
If it is too thin, it won’t span gaps; and if too thick, it will just skin over soft. Use layers if needed, and follow coverage guidance from the manufacturer.
6) Treating the weather and curing time as a thing of fantasy
High humidity with cooler temperatures accompanied by rain can prohibit proper curing. Choose a dry window and wait out the complete treatment time to see nothing but waterproofing.
