Many factors will affect the total roof repair or installation time include the degree of existing substrate repair needed, the complexity of the roof (protrusions, vents, upstands, etc) as well as the total roof area. Predictably the most reliable estimate of time will come from your appointed contractor following an initial site visit. However for comparative purposes, one of Kemperol’s great advantages is that it is applied ‘wet on wet’ – and so, on a like−for−like basis, can be completed more rapidly and more thoroughly than many cold liquid waterproofing systems. Because optimum wet−out is visible to the contractor (as the fleece becomes visibly impregnated with resin) you can be assured that there will be no, potentially weak, ‘thin spots’ that may occur with other ‘wet on dry’ systems that rely on the use of gauges to test depth of cover. Traditional Hot−applied systems will typically take longer to lay than Kemperol due to the numerous laminations used in the build up. As a general rule, the more complex the roof – configuration, upstands, penetrations and plant – the more efficient is the use of Kemperol compared to other systems, with time and cost savings of up to 10% indicated. This increases when there are many penetrations, for the reinforcing fleece is simply cut and folded to form a seamless membrane, where (for example) single ply systems require the application of some form of hot welded or mechanical fixing. |
