Roofs can't roll---so they gather plenty of moss.

       

To state that we see a lot of moss on the roofs of houses in the Northwest would be an understatement.  One of the recommendations to reduce the amount of moss growth is to install zinc strips to help control the moss.  This sometimes seems to work while other times it seems to have almost no effect.  I have no clue as to why this is.  Perhaps there are different strains of moss and some are controlled by zinc and some are not.

     In this picture of a very moss covered roof it is very clear that the various galvanized plumbing vent-pipe penetrations are in fact reducing the moss growth in the areas beneath them.

Moss on a Roof 

     In this next picture, the black algae discoloration---another type of vegetative growth that occurs on roofs----can also be affected by zinc given off by nearby galvanized components on the roof.  In this case the chimney restraint brackets and chimney flashings are helping to keep the roof clear of algae in a distinctive pattern that corresponds to the bracket and chimney installation.  It almost looks as if someone got up there and cleaned that area.

Algae on a Roof 

     Left and right of the clean area you can see the distinctive marks of where someone has pressure washed the roof---but not really consistent with the area cleaned by the zinc from the galvanized components.

     So why don't we see more zinc strips on roofs?

     I think the main reason is because they are "unsightly"----people don't like the way they look and if they aren't installed about every 3 feet on the roof they will not keep the entire roof free of moss & algae growth.  Note how in the second picture the roof is only "totally" clean about three feet below the bracket?

     I know you are waiting for my recommendation for an easy solution----but alas I have none.  Some roofing materials supposedly have zinc granules included in the roofing materials itself, and the effectiveness of this approach has yet to prove itself to me.  It would seem to me that these roofs would stick out like a sore thumb in the NW but I have yet to see this.  As near as I can tell the algae doesn't represent much of a problem for the roofing materials itself----unlike the moss which should be controlled.  Sweeping the roof during the dry season seems to be effective.  Pressure washing should always be avoided as it will take far more years off the life of the roof than sweeping will.

     The most important thing I can say about moss on your roof?----be careful up there.  Only people experienced to work on roofs should do maintenance work on roofs.

An Electrifying Anagram!

     

Last week I did my first of what I hope will be occasional, ongoing picture quizzes----if I can figure out a way to make them "psychometrically" valid.  

     Actually that isn't really as important as everyone having fun and learning something----myself included.

     I expect that the inspectors out there will have the most fun with this one as it is on the overly "technical" side.  I think everyone else should give it a go too-----and at least you can get a sense of what inspectors do.

     This time there are "five" pictures that have a "best" match in the set of "nine" pictures that follows.  The interesting thing about this quiz that is BETTER than the previous one is that the correct answers form an interesting anagram that is consistent with life----and perhaps the quiz.

     So here goes:

Electrical Quiz

 

 

     So here are the nine choices:

Electrical Quiz

 

 

 

 

  And the anagram is________________?

With the leg bone connected to the knee bone.....

    I thought I would try a little bit different sort of contest----sorry no prizes----hopefully just a little fun.  This is about seeing a picture of something and then identifying which other picture "goes with" that picture the "best."  First of all I will present 6 pictures numbered "1" through "6."  The next part is to identify which of the pictures lettered "A" through "J" "goes with each of the original pictures.

    I know it isn't fair to have three pictures that "don't count"----but don't you want this to be a challenge?  Some of the matches are very easy, while a few others I hope will make some of the Rain inspectors scratch the heads for at least a few seconds.  I am also fully prepared for a barrage of disagreement and keep in mind that this contest may have very little to do with any "defects" that may or may not be in the pictures----it is simply which ones "belong" together more than any of the others.

     So here goes:

Quiz                                                                                                                                      

     Now here are 9 pictures to pick 6 picture from that have the "best relationship" to the first 6 pictures.

quiz 

     So submit your conclusions----and "be prepared" to defend them.

Round and round she goes, where she stops, nobody knows...

     In the Bellingham Technical College, Residential Home Inspection Course (which I, along with fellow Rainers, Steve Smith, David Helm, and Rick Penn,  teach part of) one of the things we continually hammer home to the students is to:  "document, document, document."  Even when something seems unimportant or ancient history it is important to all parties involved in the transaction to document these past conditions to provide a clear picture of the home. 

     This is not so much to "project" what is coming down the road but to "document" what has happened so that if it happens again there was at least some warning---and that some areas may need to be monitored.  Perhaps the basement no longer leaks but the staining all around the paneling indicates that at some point it did.  Perhaps new perimeter drains have been installed----which might be documented as well----and flooding is no longer likely.  The staining still should be noted.

     This lesson came home to roost at a recent inspection.

     In the early fall I inspected a home and noted in the crawl space that a new interior drainage system had been installed (which was noted in the report).  Also, at several points around the foundation, there were indications of past moisture intrusion----as can be seen in the "muddy tan" discolorations in this picture (which was noted in the report).  The rusting form ties visible in the photo on top of the footing are further indications that this area has been wet.

water intrusion 

     Whether this happened during construction, after construction, or is ongoing or seasonal is difficult to determine at just one visit to the home. 

     The hole through the foundation is what we call a gravity drain.  Builders will sometimes install these drains so that prior to building the home the foundation does not become a swimming pool.  These gravity drains can admit lots of water to the crawl space if the exterior ground water is not properly drained away.  In this case a feeble attempt at making a place for any incoming water to go has been installed and connected to newer interior drainage that runs to a sump pump on the other side of the crawl space.

     There was a rotted support post, due to past flooding, that needed to be replaced, so I was called back to check the repairs about a month later----after nearly two weeks of constant rain.  Here is a picture of that same area taken at the time of the re-inspection.

Water intrusion 

     While you can see that the footing is now all wet, you can't tell from the photo that there is a little river running under the pipe and into the crawl space----enough water to pretty much require that the poor little sump pump run continuously.

     A very curious condition was causing this to happen.  Apparently this gravity drain was tied to the footing drain on the other side of the foundation.  This footing drain runs around the home to where it runs out into the back yard "somewhere."  Well apparently the drain in the back yard was somehow blocked.  This was evidenced by when the sump pump turned on water came up out of the ground like a little geyser and flowed on the surface into the back yard.  The sump drain terminated in the underground footing drain and because the drain was not draining the sump water had no place to go except up and to also fill the perimeter drain pipe back around the home and into the crawl space.  Round and round she goes, where she stops, nobody knows...

     This is a good example of how some defects are just not going to be found during a Standard Home Inspection but by documenting "everything" we can sometimes get hints of other issues.  In this case the termination of the footing drain had to be repaired to eliminate recycling the ground water back into the crawl space.

How big is your view----who are you willing to vote off the island?

A "Poli-sophical" Rant----and tribute to Wordless Wednesday's "Balloon Girl"

 The Bigger View

     Given these extraordinary economic times it is sometimes difficult to step outside of ourselves and look at the big picture.  After all, when things get tough it is more than natural to focus inward in self interest.  What this does is narrow our view to such an extent that we can no longer benefit from the many advantages of having a bigger view of what is going on.  

     As we focus on survival, of paying the bills, of feeding our families and paying the mortgage it is very easy to forget that we are all on this ship together.  When times are "tough" it can be easy to think of the people around us as somehow less important---even unnecessary.  (Some people seem to make this a way of life regardless of how tough the times are.)  We become egotistical, ethnocentric and nationalistic.

     Even our definition of the "Bigger Picture" is defined by our own limitations.  How many people's "big view" stops at their state borders, their country's borders, their religion's borders or some combination of them all?

     I would argue that none of these things are even close to the biggest view we can have. 

     Is it not so that any view that does not include everything is, by definition, going to exclude someone or something?  (The worst version of this has to be people who are "born" excluded.)  Who are we willing to vote off the island?  I would rather ask, "Who are we willing to vote off the planet?"  There may come a time when we discover that even a "planetary view" is not big enough, as there may very well be other planets that are willing to vote Planet Earth out of the solar system.  I think we need to be a lot more careful about what individuals, religions or countries we decide to vote off the island.  One of the points of a "bigger view" is that everything changes and one day it may be us that gets voted off the island.

     The tough questions are not whether this or that person is the cause of all our problems but rather how can we get everyone to see how inter-related we all are.  How much of our precious resources are we delegating to this endeavor?  Precious little I would argue.  As a species, one step at a time, we have come to where we are in history.  I think we are all culpable----to think otherwise is to define the trap our mind is in.  One way to look at this is to see us all as "one being" and that our individual separateness, while real on one level, is an illusion on the level of the bigger picture.  Do we cut off our arm to spite our face? 

     What would it take for the entire planet to see that Economic richness in one part of the globe requires poverty in another?

     What would it take to see that plenty of food in one area requires that there be inadequate food supplies in other areas? 

     What would it take to see that polluting the farm lands in the land of Dorothy will ruin the shrimp harvest in the Gulf of Mexico?  All over the planet we have all these not so subtle versions of, "f___ you" going on with only lip-service given to "caring."  Does anyone seriously doubt the relationship between "Hummers" on the streets of America and "Humvees" around the world?

     There will always be this balance between the extremes.  It would seem that a larger view on the part of all of us would enable the extremes to be somewhat moderated.  The endless waves, or cycles, of existence can't be changed; and, it is my opinion that the extremes can be lessened to the point that we neither have people so rich that they don't even know how rich they are, nor children that die before they are weaned from their starving mothers.

     It is this lack of a bigger view----a view outside of the selves---that has created the tremendous gulf between the "haves" and the "have-nots" around the world, and has radicalized many people to the point where they have no room for a bigger view----where all that matters is their small view----survival----and "Pink Balloons."

     No matter what our economic position this should sound familiar to everyone on the planet.  We all get trapped in our own small view.  We all at times say, "My way or the highway."  We expect our leaders to maintain our small view----to kill other people and their small views in order that our own small view survives.  We do this in the name of "progress" or "religion" or "race" or "country."  It really doesn't matter what clothes we dress it up in as long as it allows us to "dehumanize" those with undesirable views; and, make starvation, disease, and poverty somehow palatable.

     I think some reasonable questions to ask of ourselves are:  does my view open doors or close doors; and, does my view require that others be like me----or else?

     "But, but, but.......," you say. 

     It would seem to me that all "buts" are merely attempts to maintain the way things are----to define and bolster a smaller view.

     We expend vast resources to maintain this poor approach.  What good does it do a people to have tremendous physical wealth if they are morally and spiritually bankrupt?

     The real question is:  Do we have the balls as a planet to act in a way that everyone is benefited?  Are we capable of a "HUGE VIEW"----bigger than individuals, states, countries, religions, races and even the Beatles?

     The answer for me is actually quite simple:  "We must." (Or----to quote someone smarter than me, "Yes we can.")

The "I canduit" conduit!

      I have done posts in the past about improper wiring to disposals.  It is a defect that I see so often that repetition is warranted. 

     Anyone can go to the Big Orange Tool Box or similar types of home maintenance stores and buy a garbage disposal.  How difficult can it be to hook up a disposal?

     The part of the installation that I find wrong the most is the electrical hook-up.  This is especially true when there is no plug-in type cord, and instead the disposal is "hard-wired."  All "hard-wired" means is that the unit can't be unplugged----and instead is wired continuously all the way to the breaker panel.  When wired this way it is important that the wire that runs from the wall to the disposal be of proper type and be properly protected from mechanical damage.  Often this wire is run in flexible conduit from the connection at the wall. 

     Installers that don't know proper connection methods (aren't electricians) sometimes just hook the wire that comes through the wall directly to the disposal.  In this picture we can see where the wires have been run inside flexible conduit but the conduit is badly damaged at the wall in the background and is not connected properly to the disposal in the foreground.  Notice also that the ground wire is not connected to the disposal.  It is important for disposals to be properly grounded to prevent persons contacting the disposal from being the shortest path to ground in the event of a short in the unit.

Bad wiring to disposal 

     In this case it would seem that the installer knew the wiring should be in conduit but they just didn't know how to make the connections at the ends of the conduit----more like "I cantduit."

Everyone loves "What is wrong with this picture?" type contests.

     Now I am sure this will be easy for all the inspectors out there so I would appreciate it if they would all refrain from commenting to give everyone else a chance to have some fun.  So the question is:  What is wrong in this picture.  And let's see who can come up with the most "creative" excuse for how the defect got to be this way.

What is wrong in this picture

Do you have parts that need support?

     Well support comes in all shapes and sizes.  There is moral-support, child-support, spousal-support, support-hose, military-support, and athletic-support-----we can all use a little support here and there.  This is about "foundation-support" and how without enough of it, bad things can happen.  Not always "REALLY" bad things----as in this case----but perhaps bad enough to make the floors springy or squeak; or for doors to not close properly.  In some cases, all it might mean is that all of one's marbles would run to the same place.

     Many homes that have crawl spaces have support posts spaced along central carrying beams.  These posts, depending on the spans and sizes of beams, might be anywhere from 4 to 10 feet apart.  Modern requirements call for these support posts to be attached at the top and the bottom.  The concrete footing for the support post in the following picture is out of sight under the plastic ground cover.  We can clearly see that it is not attached at the bottom----in fact the post is ¾" from touching anything. 

Support post 

     Looks like it is time to bring out the "lumber-stretcher" and make that post long enough to make contact with the footing and then we can properly attach it.  Again, this is brand new construction----the contractor hasn't even packed up his truck yet----better get him back down here.
