When Inspecting old homes I often come across interesting methods for shoring up sagging floor joists.
This is an example of one way not to repair a crumbling porch. Over time the elements got to the outer later of this porch brickwork. Mortar and bricks became loose and fell out. What the home owner did was to provide bracing to keep addotionam courses of block from falling out.
As stated in the video, we had over 40 inches of snow here in Rochester during the month of December. Then to top it off we had above freezing weather and rain. This resulted in ice daming on most all homes in the area.
We had a lot of snow this past winter and apparently the load exceeded the design specifications of this garage roof. Or maybe deferred maintenance caught up with structure. Whatever the case, it appears this garage is near the end of it's useful life ;-).
Your home inspector saw this as I was passing by and couldn't resist stopping and taking a picture.
Ice dams can be a problem this time of year here in the Rochester MN area. Snow melts on the roof and freezes at the eaves leaving a dam. Continued melting will pool up behind the dam and has the potential to seep under your shingles, resulting in water damage to both the roof deck, as well as the walls and ceilings.
When a basement wall starts to crack, and those cracks open up horizontally, it can be a sign that the wall is being pushed inward. Many times the horizontal cracks will line up with the frost line in the outside soil.
This video shows the impact of hydraulic forces on a basement wall. What are hydraulic forces...Water and frost pressures.
Most home inspections find that the dampness in basements can usually be traced back to lack of gutters and downspouts and/or poor drainage at the foundation. By correcting above-ground problems you can help to prevent structural damage to your home, as well as dry up those basement damp spots.
