Im starting the moisture intrusion course

Good work, Lenard. I feel this is a most useful course, and as a home inspector will run into moisture intrusion quite often.
Take notes and keep us posted.
Good luck.

You are quite welcome, Leonard.
Learn about measuring moisture in building materials. Seeing residential one and two story homes structures are wood based. Purchase a relatively inexpensive moisture meter for now.
Moisture intrusion through the envelope. Leaking roof membranes. The need for flashing throughout the exterior assembly.
Keep us posted with analytical remarks. Here is a sample: Wood moisture content, or the amount of water in wood, is a crucial factor, especially for construction. Typically ranging from 6-19% depending on the application and location.
Acceptable Moisture Levels in Wood – Moisture Content
Thanks again,and yes wood can soak in alot of water.I found a window recently that was 48 % water on my meter.I think the wooden frame around window was water logged. Leonard Clemens

I grew up in Portland and have spent a lot of time at the coast. When I got into building inspections I quickly realized contractors and inspectors there deal with all the problems we have in the valley 10-fold. Rain, wind, salt… houses there age in dog years!

Yes ,I have owned a house in Portland,and I spent alot of money to keep the water out.I have thought of moving back.The price of houses is way up.Could be more money for home inspectors
OK, I got a question on the course.
So, here I am in Section 2.3.1. What Is a Weather-Resistant Exterior Wall Envelope (WRE)?, at Table 7 and I’m not clear in how to calculate the Overhang Ratio.
W = Overhang
H = Height of walls
The problem is that the table does not specify if both are measured using the same measurement unit or if the overhang is measured in inches or feet divided by the height measured in feet. If they are both measured in the same unit, you would almost never get the higher overhang ratios except on a porch or something.
