SDS is owned and operated by a journeyman roofer and waterproofing installer out of Marysville WA with well over a decade of experience in the commercial industry And in the PNW where it is known to rain ... A LOT!!. This is how we know just how detrimental even one small leak can be to a contractor or building owner. We have seen it too many times. The day a tenant (whether a business or housing unit) has to be relocated, the costs can start stacking at thousands of dollars a day. We strive to save you both time and money by combining roofing knowledge, the highest quality testing with the highest quality equipment, and dedication to delivering exceptional service. We will not leave the job until it is finished and you are satisfied with the results.
Please contact us if you cannot find an answer to your question.
No we do not.
No! it's not something that can be calibrated. The equipment sends out 9 volts of electricity and also must grounded to a conductive substrate. If there is a breach in the membrane, the circuit closes and an alarm sounds.
Almost any low slope roof or waterproofing membrane i.e. TPO, hot rubber or a number of cold fluid applied products. The substrate directly under the membrane must be conductive so if it's not installed on concrete, a conductive primer must be applied directly under the membrane.
