#3 IN AN OCCASIONAL SERIES:

It looks like that 1960's contemporary in Chevy Chase is going to get a new roof and a new lease on life!  I am very happy for the homeowners, because the roofing contractor has agreed to tear-off  his new roof as well as the old roof beneath, and replace everything from scratch, to my specifications.  That's the right thing to do and I applaud him for stepping-up -- particularly because it is going to be very expensive for him.

Even so, the homeowner has spent money for structural restoration work that could have been avoided, if only the roof had been properly installed.  Not to mention the cost of my time in diagnosing the problems and negotiating the solution.  If there is any silver lining, it is that we caught the problem before it spread into the living space.  And we will take advantage of this opportunity to increase the insulation of the roof and greatly reduce heating and cooling costs in the long-run.  Still, it was an expensive lesson for my clients I'm afraid; but given the enormity of the problem it is a pretty good resolution and I'm glad I could help.

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.

I am often asked if it makes sense to remodel a home in phases; and the answer is an unequivocal... it depends. 

On one hand, there are some great deals to be had today while the remodeling market is depressed; you'll get more for your money now than you will later when the market recovers. And it always costs more to build a project in parts than it does to build it all at once.  Think "economy of scale".

One the other hand, there's plenty of situations where phasing the work is a good way, if not the only way, to go.  As an architect devoted to residential remodeling, I'm seeing a strong up-tick in people taking this course lately. 

So here are a few issues that commonly factor-in when considering a phased renovation:

• Timing - A smaller project can finish sooner.  If you have a baby on the way, that's a strong motivator!
• Financing - If you are funding your renovations with a home equity loan, you might first want to tackle projects that deliver the maximum boost in home value.  Then the house will re-appraise at a higher value, your equity will increase, and you can tap that new equity for the next phase.
• Uncertainty - For any number of reasons, people are sometimes unsure if they want to commit to the entire project now; but they still want to get something done and feel like they're "moving ahead".

Many of my clients in the older neighborhoods of Washington DC and surrounding suburbs (Bethesda, Chevy Chase, Potomac, etc) choose this path with great results.  But the critical step is to first develop a "Master Plan" -- a vision of what you want the home to eventually be, and how you are going to get there. 

This bears repeating: YOU NEED A MASTER PLAN!  Do not try this yourself at home -- someone's gonna get hurt.   Seriously, you can waste a ton of money if the phases are not thoughtfully planned with an eye on the big picture.  A small up-front investment in architectural design will reap huge dividends.

I was up on a client's roof in Chevy Chase the other day (this is what an architect does for relaxation) when I ran into my old nemesis - the phrase "That's how we always do it", and I was reminded yet again of the infinite  ways that homes can be tragically damaged by ignorance - even by those who are well meaning.

Houses are complex; they are living, breathing organisms that stretch, shrink, vibrate, and sweat - just like people.  But too many architects, contractors, and homeowners don't understand the science behind houses and what keeps them healthy.  All too often, they use a stock answer to solve a unique problem.

In this case a roofer installed a new built-up roof over an existing one, not realizing that his new roof would act like shrink wrap and trap moisture beneath it.  He didn't think through the particular needs of this 1960's contemporary, with heavy timber beams and exposed roof decking, which served as the ceiling for the house. 

Humid air from inside the house was rising through the roof deck, through the old roofing via thousands of nail holes made when installing the new over-roof.  Here the moisture condensed into water and seeped back through the many holes into the structure below.  Gradually the water collected at the eaves, where it rotted the roof decking and the heavy timber beams. 

I was looking at a total failure of a 4-year old roof as well as heavy damage to the underlying roof structure.  The repair will be complex and expensive, but the real tragedy is that it was completely avoidable.   When I asked one of the roofers why they installed the roof this way, he uttered the dreaded phrase "That's how we always do it".  But most installations of this type of roof occur over a ventilated attic - not over a cathedral ceiling of exposed timber frame - and that difference is everything.

Washington, DC and the older suburbs of Bethesda and Chevy Chase are home to an astonishing variety of house types, each with particular problems and needs.  So the next time you hear "That's how we always do it", call an expert.  It's never that simple.
