Exhausting! The building codes and their limitations.

Seems like a “cut-and-dryer” case of what were they thimkin?!

As anyone that regularly reads my posts knows---I love standing seam metal roofs.  Inspecting them is difficult if they are steep, but because a fair amount of skill is necessary to install them, they usually don’t have a lot of issues that are not going to be apparent from the eaves---assuming you can get to the eaves.  I was able to get to the eaves at two locations on this duplex, and overall the roof looked great.

The pitch is 7/12---not an exactly friendly pitch for an asphalt roof---and certainly not for a steel roof.  A slippery slide at the playground is not much steeper than this---some are less steep.  Add to that, that it was raining at the time of inspection, guaranteed that I would not be venturing onto the roof.  From the eave one thing was noted on this 5 year old home.

The dryer exhaust cap.

How is anyone going to do routine maintenance on this vent cap?  While the installation meets code requirements, I still find the installation wanting.

Dryer Exhaust cap 

Even with the best filter/screens in dryers, these caps will eventually plug with lint.  Cleaning at least a couple of times a year is necessary.  At least there was no screen in the cap. 

The “close-up” of the cap shows a fair amount of lint building up inside the cap---who can tell whether the flap opens properly or not?

Plugged exhaust cap

I have no clue as to a viable solution to this problem, when the dryer is not located on an outside wall of the home---but surely some solution is warranted.  If no other route for the exhaust can be found, then establishing a maintenance program with someone trained and qualified to be on this type of roof a couple of times a year may be warranted.

Perhaps it is time to make an adjustment to the codes---and/or common sense.

The receptacle pictured below is a standard dryer receptacle. It is installed next to the stacking washer dryer and was likely used for the dryer, previous to the dryer being converted to gas. What is a handy sort of guy to do with a left… more

Being grounded is not just a statement of one’s well being.
There was a time, in the not so distant past, when the only means of grounding the house electrical system was accomplished by connection of the grounding conductor to the metal water pipe coming to the house. There are still a large number of such… more
6000 sq ft of nasty!
Most inspectors will tell you that they don’t like crawl spaces. Like Mickey Rourke in Barfly would say (not about crawl spaces, but about cops), “I just feel better when they are not around. ” The problem is that crawl spaces represent a… more

No testing necessary!

Time to pull the plug on this installation!
Personified, bona fide, certified, deep fried, electrified---or more accurately---mortified! The first thing that stood out as I looked at the house was the cool wood box under the roof overhang. It had a nice pull handle, a… more
So you think you know what your roof gutters are for?
As one can imagine, in the lush and green Northwest---stuff grows! It does not take long for houses to become buried in vegetation. Since people are unwilling to install a moat of pavement all around their homes, to keep vegetation at… more
Unpleasant odors in the bathroom? Just turn on the fan!
It used to be a very common practice to terminate bathroom exhaust fan ducts at the screened bird-blocking of the roof overhang. Everyone has likely seen bird-blocking and knows what it is. Bird-blocks are essential components of the roof… more
