Liquasil’s cut edge corrosion treatment has been developed by our Chartered Building Surveying practice to overcome the common problem of cut edge corrosion in metalprofile roofs on commercial property.
We appreciate that other systems are available and that there is a long-established procedure to treating cut edge corrosion.
However, our surveyors noticed after inspecting many different metal profile roofs, that the generally accepted methods can actually cause corrosion, rather than solveit.
By actually lifting roof sheets and examining the undersides, it became apparent that roof sheets tend not to rust from underneath and in most cases, the rust is confined to the top of the uppermost sheet.
Consequently, ourbuilding surveyors embarked on a study of older roofs that had previously received cut edge corrosion treatment on overlapping sheets, where the gaps between them had been sealed with a mastic or sealant.
On this previously treated and sealed roof, moisture became trapped, resulting in the extensive rusting of both top and bottom sheets. Still think gap sealing is a good idea?
In most cases, it became apparent that rather than solving the problem of cut edge corrosion, the sealing of the overlapping joints can actually create as many issues as it solves.
The reason is simply that by walking on the roofs, the seal between the roof sheets is often broken, though this break can rarely be seen by the human eye, unless pressure is placed on the roof sheets to identify the break.
Even installers of these systems agree with our analysis and often report that they hear a characteristic “popping sound” of the seal breaking as they walk across the roof during their installations.
The result is that during rainfall,water enters the broken seal through capillary actionand becomes trapped between the upper and lower roof sheet and rust begins to form from underneath. Eventually rust breaks through the original treatment.
Closer examination of these surface rust spots often identifies a much larger rust problem than originally existed with the cut edge corrosion.
Our own tests on previously sealed edge shave consistently shown that water becomes trapped and rust develops from the underside of the roof panels, rusting both top and bottom sheets in the process.
We therefore question the logic of sealing overlapping roof sheets and our discussions with metal lurgists and roofers back up our assumptions.
Consequently, the Liquasil cut edge corrosion treatment system has been designed to treat only the topsheets and not to seal overlapping roof sheets.
This results in a far easier application method, significant material and labour savings and an altogether more robust solution to cut edge corrosion problems.
We do, however, offer an optional gap sealer (lapsil),to satisfy building surveyors who prefer to specify sealing the overlapping roof sheets.
Because Liquasil Ltd is owned by building surveyors, our liquid roofing solutions are designed to actually solve the problems associated with commercial roofs.
The Liquasil Cut Edge Corrosion System is so good, that from November 2016, all installations with a contract value exceeding £10,000 will come with a 12-year latent defects warranty as standard, when installed by a Liquasil Approved Installer.
