The roof catches and sheds a tremendous amount of water over the course of a year. How a builder details that roof impacts that buildings ability to handle that load with attention paid to:proper shingle install, valley, step flashing, cricket installation, proper sealing of penetrations and proper attic ventilation.
A home's mechanical systems play and important part in keeping it dry and free from moisture problems that can cause callbacks for builders and health and comfort problems for homeowners. In this video we will take a look at the following systems and their interrelationships;
Outside air intake
Proper PVC and copper install
Sealing/flashing wall and roof penetrations
How insulation is installed and detailed also impacts the management of moisture in a new home. A number of issues must be properly addressed, as in this video and: Kraft faced insulation, insulate behind tub/shower units, proper sealing of penetration, caulking and seal where you see light.
Like the roof, the walls and their exterior finish must be properly detailed to shed a tremendous amount of direct, run-off and wind-blown rainfall. In order to properly handle that water, care must be taken with the following details;
Wood (Vinyl/Aluminum Siding, Hang Siding, Proper J channel/starter & strip installation)
Head and bed joints
Maintaining a clean air space
Double layer weather membrane
Proper door and window flashing
|Flashing and Runoff Controls
Finally, dealing with the holes in the various building elements and how we direct water away from them and the main building elements is critical to moving the water out. In this video we take a look at a number of these issues, including: window and door flashing/sealing, review all roof and wall penetrations, proper gutter and downspout sizing and installation, splash blocks and final grade details.
