Sarnafil Lead Alternative
All roofing systems will, at some stage, reach the end of their
functional life. However the cause of a roofing failure may not solely be down
to the roof waterproofing failing. Mechanical damage, storm damage, poor
design and poor installation are all factors that can affect the integrity and
performance of the roof waterproofing. Each of these factors, and more, need to
be assessed when an existing roofing system is deemed to have failed.
When selecting the replacement roofing system, compliance with the
Building Regulations needs to be achieved and the refurbishment solution needs
to be durable, have minimal environmental impact and be installed by fitters
trained in the products installation.
