#2 IN AN OCCASIONAL SERIES

Well, I was up on the roof of that 1960's contemporary in Chevy Chase, MD again yesterday, and the problem is MUCH worse than I imagined.  In addition to water vapor questions, we now know that the roof is actively leaking at every skylight (there are ten) and at the chimney.

In every case, the problem is faulty "flashing" - the material (aluminum, copper or bituminous membrane) used to protect joints between the main roofing material and the various items that pass through the roof.  Now, I've seen a lot of roof problems over the years, but this beats them all, hands down. 

We cut test holes into the flashings and water just poured out.  Not a little trickle, but like when someone cuts an artery; the water spurted-out in streams.  In twenty five years as a residential architect, I've never seen such a total failure of roof flashing. 

This bears a quick note about flashing; in all roofing systems, flashing is inherently the the most vulnerable link because it manages the joint where the main roofing material is interrupted by something else -- like skylights, pipes, chimneys, etc.  Roofs rarely leak in the main body of the roof, but more often leak at these joints, where flashing is the primary defence.  Faulty flashing = leaky roof. 

And a word in defense of skylights:  to paraphrase the NRA, "Skylights don't leak on people -- People (installing bad flashing) leak on people".  Most modern skylights are so water-tight you could use one for a boat.  And properly designed and installed flashing WILL NOT LEAK.   So don't shy away from skylights; but DO invest in quality and make sure a true professional is in charge of specifying and supervising the installation.

Final thoughts... Do not hire a roofing contractor just because a friend had a good experience with them.  That's just putting your fate in the law of averages - and sometimes you'll wind up on the wrong side of that average.

Our client - a single female professional - purchased an old rambler on a hillside lot overlooking the Potomac River; but the house practically ignored the landscape. It made no attempt to take advantage of the extraordinary site - in fact this house could have been in a subdivision just about anywhere.

In expanding and re-considering the design of this home, we took the opportunity to create a cottage that reaches out into the landscape and enfolds the homeowner in nature. Ample windows and/or doors on at least two sides of each room provide panoramic views at every turn, while the mass of the house is broken-down into smaller components, ensuring that the house is "of" the hill rather than on it. It is a magical thing to float above the azaleas, among the trees.

Before & After:

THEY DON'T BUILD THEM LIKE THAT ANYMORE!

I love that phrase.  It usually escapes from a new client, when we are touring another client's just-finished renovation.   Sometimes we're admiring an exquisitely crafted stair railing or mantelpiece.  Or it might be a lovely paneled portal or a fabulous cast iron grille.  My personal favorite was a pocket-screen-door, that disappeared into the wall, next to a front door.  In each case, my new client pauses and looks wistfully at some such detail and observes "They don't build them like that anymore."  It's the sort of detail that they don't expect to find in today's construction... except we've just built it!

That's one of the most satisfying moments for me.  I'm always so proud of our carpenters and architects, for refusing to give in to the myth that true craftsmanship is not achievable today; there's simply no reason why that should be so.  Instead, I'd argue that given the enormous technological advances of our time, homeowners should expect new renovations and additions to be both designed and constructed better than an older home.
