Guardian Seal is a revolutionary new liquid membrane roof coating that works on many different roofing surfaces in various conditions; Guardian Seal has a large number of applications however if the underlying condition of the roof isn't sufficient to support the membrane a warranty cannot be provided on the application.

Guardian Seal and Guardian Seal Pro have different warranties dependent on the circumstances that can vary depending on the application. Provided the underlying roof condition is sufficient to support the membrane typically a 2 coat application will have a warranty of 10 years or a 3 coat application that will have a warranty of 15 years. We will clarify the warranty on a case by case basis and include this information in your quote for your reference.
Guardian Seal liquid membrane applications start with a chemical clean to kill moss and mold, then a thorough water blast to clean the entire surface. From there patching, masking and drop sheets are used to prepare the surface & a rust buster treatment is applied to stop any further degradation of the roofing material. Two coats of self priming liquid membrane coatings follow and complete the coating system. This process typically takes between 2-4 days end to end and is weather dependent.
Scaffolding is not often required for Guardian Seal installations under 25 degrees however health and safety compliance is on a job by job basis and we will discuss this with you in person and include the requirements in your quote to ensure safety protocols are upheld across all applications and your quoted price is all inclusive of everything needed to get the job done.
