Mark Parlee

Mr. Parlee is a building consultant with 47 years in the construction trades, having worked as a framing and siding carpenter, homebuilder, remodeler, and exterior renovator. While working in these trades he has built, or dismantled and replaced, the exteriors on several hundred homes. This has allowed him to see what works, and to also see the problematic details that have led to moisture intrusion into the building envelope and to effect corrections. Mr. Parlee currently uses the expertise gathered over his life’s work as a consultant on construction defects and moisture intrusion as an expert witness, and as a seminar presenter for inspection organizations for continuing education credits, and for builders looking to better their quality. He is EDI (Exterior Design Institute) certified as an EIFS, Stucco and Stone Inspector/Moisture Analyst/Quality Control and is also certified by EDI as a Building Envelope II, Steep Slope Roof Inspector and was one of the instructors of the first EDI Stone Veneer Inspection Certification seminar. As a member of the Board of Directors for EDI, he is involved in updating the curriculum and writing new curriculum to keep courses in step with the most current technologies. Mr. Parlee is a certified Level I Infrared Thermographer and Certified Residential Thermographer. He has been a guest lecturer for Architecture Forensics at Iowa State University. Mr. Parlee has also attained certification as a Building Envelope Investigator through BESI (Building Envelope Science Institute). His articles in Journal of Light Construction have been numerous, including “Rescuing a Manufactured Stone Wall” (Dec ’08), “Repairing a Rotting Roof” (June ’10), “A Rot-Resistant Chimney Chase” (Nov ’11), “Mixing Cladding and Stick-On Stone” (Aug ’13), “Best Practices: Adhered Masonry Veneer” (Oct ’13), “Best Practices Stucco” (Dec ’14), “Common Siding Failures” (Oct ’15), “Getting Kick-Out Flashings Right” (Apr ’16), “Common Roofing Errors” (May ’16), and “How to Destroy a Wall in Two Easy Steps” (Sep ‘17). Mr. Parlee has culled his archives of thousands of photos of exteriors in need of repair and addressed the needed proper correction in power point driven presentations for continuing education credits to the National Association of Home Builders Remodelers Council, the American Institute of Architects Iowa Convention, Minnesota Society of Home Inspectors, MidAtlantic Chapter-ASHI (NJ), St. Louis ASHI (MO), Indiana ASHI, Garden State ASHI (NJ), Keystone ASHI (PA), NoVA ASHI (VA), Professional Home Inspectors of Missouri, Oklahoma Residential & Commercial Inspection Association, HouseMaster (CO), JLC Live Northwest (OR), American Society of Home Inspectors National Convention (Inspection World 2015 through 2020), and Alliant Energy Builder Training (2015 through 2017), and local and regional chapters of ASHI.

Course Title: Course Title: Moisture Intrusion in Construction

Delivery Method: Live Online

Course Description: This course examines several common design and construction practices that can lead to moisture intrusion into structures. At the conclusion of the course, learners will understand why and how these practices fail, how to test for and document moisture intrusion, and the proper protocol for repair of moisture damage.

Learning Objectives:

Learning Objective 1:
Learners will be able to identify commonalities in failures, the health and safety hazards posed to building users, and techniques for preventing moisture intrusion when working with exterior insulation and finish systems (EIFS), stucco, manufactured stone veneer (MSV), brick, lap siding, flashing and windows.

Learning Objective 2:
Learners will be able to identify the most common moisture intrusion locations, and avoid and mitigate damage due to roof leaks and failures, poor drainage around foundations, and water infiltration into basements and crawl spaces.

Learning Objective 3:
Learners will be able to identify building code requirements for moisture barriers and insulation, and discuss and reference case studies of various repair protocols for specific types of moisture damage.

Learning Objective 4:
Learners will be able to discuss and reference technical manuals, building codes and industry design standards that design and construction professionals can use to avoid moisture intrusion into buildings and structures.
