Solid evidence of the crime.

leakingHome inspectors will often look for “circumstantial evidence” of issues around the home.  Things like water stains will be identified as evidence of at least past moisture conditions or possibly ongoing moisture issues.

For example if it has not rained for 2 months, a roof that leaks and stains a ceiling below might test negative for moisture at the time of inspection, but the client should be cautioned as to concluding the roof does not leak.

Other stains might only become active under specific conditions that are not duplicated at the time of inspection.  For example, it is raining hard outside but the only time the stain would test positive for moisture is when the wind is blowing form the east instead of the more usual West.  This is why most home inspectors are not going to crawl out on a limb and categorically state the roof does not leak.  This is especially true if there is no actual physical explanation for leaking can be found at the exterior.

Stains should be monitored for signs of ongoing leaking, or if stains reappear after proper repairs the area should be further evaluated for.

Inspectors will often note stains at the corners of roof overhangs, the soffit area, and typically test them for moisture content with a moisture meter--if they can get to them.  Gutter corner-seams often leak, and unless it is raining the leaking might not be noticed, especially if there is no mark on the ground consistent with leaking above.

I tell clients the best time to check your gutters for leaks and overflowing is when it rains---it likely will be difficult to tell definitively otherwise.  We want “solid proof” not “circumstantial evidence” as to what is going on.

When it is really cold outside, solid proof gets a little easier to identify because perhaps the evidence actually remains after it has stopped raining.

Carpenter Ants and Grow-Ops
Seems like this would be an odd juxtaposition because the last thing our houses would need would be Carpenter Ants on drugs. Carpenter Ants are interesting because they don’t eat our houses they merely mine the wood and other materials as a place… more
Getting high and why we don’t get high enough—often enough!
One of my pet peeves about building homes is that they are rarely built high enough. There are minimum clearance, to finish grade, requirements that would be so easy to comply with if houses were built two to four inches higher than they are. Why… more
When you are loopy and you can’t figure out why
In the scheme of things this is not a big deal, but there is a concept known as “best practices” for a reason. Take a look at the following picture and see if you can tell what is “wrong. ” Well, in the picture there is actually nothing… more
OK---so now let’s see if we can get the repairs repaired!
It is not unusual for home inspectors to call for repairs on the homes we inspect. This does not surprise anyone. It is not even unusual for homeowners to call for repairs of work they have done to their homes—even if a home inspector is nowhere… more
How about Electric Rodent Traps?
Once rodents have gotten established in your home, or should we say, once rodents have made your home their home, it can be very difficult to get rid of them. They can make a big mess of an attic or a crawl space resulting in thousands of dollars… more
When downspouts spout off!
I have always commented in my inspection reports on the termination of upper roof drains at lower roof surfaces. The theory is that directing a heavy flow of water in a concentrated area will produce more wear than the rest of the roof will see… more
The electrical inspection was like poetry
It is not very often that I can say this about the electrical system of any building. Considering the building had five tenants, and 11 electrical panels, the electrical issues were pretty minimal. This is often the case with commercial… more
Thinking like a six-year-old
I find that homeowners often have dangerous things around their homes that they are unaware of. This post is done in the spirit of keeping homeowners vigilant as to serious safety issues--and in particular combustible gas issues. If you have… more
Avoiding your own premature cremation.
If you think electricity is always trying to “go to ground”—you may be the victim of urban legend. For a home inspector this has to be one of the ultimate “urban legends. ” It is a widely held belief (that is further promulgated by inspection… more
