• � . <br /> Certified�: <br /> Moisture Testing <br /> Interpreting Moisture Levels <br /> Wood/Fiberboard/OSB(Scale 1) <br /> 19%is the moisture level construction lumber must have when removed from the drying kilns.After <br /> construction has been completed,the wood frame of the home will continue to dry and stay dry if not exposed <br /> to moisture intrusion. <br /> 6-15%: Normal dry readings in sound firm wood or fiberboard sheathing. <br /> 15-19%: Readings in this range show slight moisture intrusion,a small leak or limited exposure with the <br /> ability to dry <br /> 20-26%: Moisture at this level is a sign of moderate moisture intrusion occurring through a larger leak or as <br /> a result of limited ability to dry quickly. Identifying how moisture is entering the wall and stopping the <br /> intrusion can prevent damage to your home. Circled blue areas show moderate moisture intrusion.At this <br /> level,maintenance procedures typically remedy the issues. <br /> 27-40%: Areas with moisture levels greater than 27%over periods of time have or eventually will have <br /> � moisture damage.Circled orange areas show where higher levels of moisture were found and where <br /> �'� structural dama e is hi hl <br /> g g y possible OR LIKELY. <br /> None: The sheathing in areas where moisture intrusion has been occurring over time is likely to have <br /> sustained structural damage. Deteriorated sheathing not strong or firm enough to probe causes the test <br /> probes to easily punch through to the wall cavity behind. With no material to probe,the moisture reading <br /> will be noted as 0. In areas where a stud or other material is located behind the deteriorated sheathing,a <br /> moisture reading will be taken in the stud or the wall cavity and noted as,for example, 12/None. Circled red <br /> areas show where the inspector has assessed the areas to have structural damage. <br /> Gypsum Board/Sheetrock(Scale 3) <br /> 0.1-0.6%: Normal dry readings. <br /> 0.7-1.5%: Readings in this range mean moderate moisture intrusion is occurring. Identifying how moisture is <br /> entering and stopping the intrusion is necessary to prevent damage. Circled blue areas show signs of slight <br /> to moderate moisture intrusion. <br /> 1.6-50%: Areas with moisture levels greater than 1.6%have or eventually will have moisture damage. <br /> Circled orange areas show where higher levels of moisture were found. <br /> None: Areas where moisture intrusion has been occurring over time are likely to have sustained structural <br /> damage. Deteriorated sheathing not strong or firm enough to probe causes the test probes to easily punch <br /> through to the cavity behind. With no material to probe,the reading will be noted as 0. Circled red areas <br /> show where the inspector has assessed the areas to have structural damage. <br /> Weather Considerations <br /> Meteorological conditions affect moisture measurements in various ways,all of which are factored into our <br /> assessments.After a rain, leaks into the wall system will lend higher moisture readings.These higher readings if <br /> given the opportunity to dry before the next rain will change to lower readings. During drought conditions, it <br /> becomes necessary to rely primarily on the damage assessment and visual observations to determine points of <br /> intrusion.Colder weather also tends to result in slightly drier readings than in the warmer months. High humidity <br /> levels do not typically affect moisture readings unless long term high humidity levels are maintained. <br />
