Liquid-applied membranes are especially effective for renovation, complex detailing and projects where a seamless system offers practical advantages. But not every roof is automatically suitable.
A cool roof combines waterproofing with high solar reflectance. On large flat roofs in particular, this can be relevant for thermal load, comfort and sustainable renovation.
Completely stripping an existing roof is not always the only option. Under the right technical conditions, a liquid renovation system can extend service life with less intervention.
