A New Roof at Westview

In a perfect world, all fixer-uppers would have a new roof and those of us crazy enough to take them on wouldn't have to worry about that one little detail.  Unfortunately, when people give up on a house, it seems that the expense of replacing a roof is one of the reasons they give up.  The house we live in had multiple leaks when we first bought it and the remains of some really bad attempts at plugging up missing flashing with roofing tar and caulking.  We got the flashing fixed and a few roofing tiles replaced and we've been dry ever since.


At the Westview project house, we knew there were roofing issues when we bought the house.  The blue tarps were the first clue.  The old curling asphalt shingles that blew off in the mountain winds were the second.  We've had a roofer lined up for several months now, but since we're in no hurry, we told them they could put us later in the queue.  Well, this week, they finally got to us.  They took the old roof off Monday morning.  Fortunately, despite the terrible condition of the old roof, it hadn't been leaking enough to damage the oak decking so little work had to take place before replacement could begin.  As of yesterday afternoon (prior to the thunderstorms, fortunately), we had a new asphalt architectural shingled roof!  Very nice, except that it highlights the peeling paint on the attic windows. 


The other slight problem was that the power line to the house was rather precarious and the debris coming off the roof pulled the power line free from the house.  So, we called to have the power company look at it since the roofers mentioned it had sparked when it pulled free and we didn't want to burn the house down.  The power company came by, took one look at that old power line, cut it, and took the meter.  Sooo, now we have NO power.  We only had one operational outlet anyway because the wiring in the house was downright dangerous, but this sets us back a bit since we don't own a generator.  We're investigating now how to get minimal power for construction.  At least painting windows can be done without a power source!

What's in the Walls?

An interesting thing about gutting an old house to add insulation and new wiring, plumbing, and HVAC is what you find (or don't find) in the walls.  Our project house is definitely a vernacular house added onto and built with whatever the carpenters had.  Some walls had plaster, others old sheetrock.  When we got to the studs, we found that none of the walls had insulation and that the sheathing was flipped over and reused painted siding from another building.  Must've been pretty cold and drafty in there with the mountain winds blowing in winter.

We've also found that you can look straight up the wall cavities from the first floor to the second.  In other words, we've got balloon framing.  Today's buildings generally use platform framing where each floor is a platform extending to the outside wall and the wall studs are attached to the floor above and sit on the floor below.  With balloon framing, longer studs are used that reach from the base of the first floor to the second floor ceiling.  The floor joists are nailed to the wall studs.  The structure will usually have some bracing and the sheathing also helps to strengthen balloon framing.

Balloon framing doesn't meet today's building codes because the open walls create a chimney that can transfer smoke and flames throughout the building quickly and with devastating results.  So, one of our tasks is to add fire blocks in the walls.  We'll be insulating, which will reduce the chimney effect, but we'll also be adding 2x4 blocks that fit between the stud bays to further block airflow.  Since we've got real 2x4s and the distance between studs is probably not uniform, we won't be able to simply use big-box-bought lumber and cut all the pieces to the same size.  It'll be time consuming, but worth it in the long run for the safety and comfort of the new occupants.

Beware the Electricity in Your Old House

If you are rehabilitating an old house, it's a good bet that the wiring in the house is downright scary.  And, since bad wiring can cause a fire and burn down your new investment, it's best to have a professional assess the situation and give you the bad news about rewiring.  As the DIY'er, here are a few red flags that suggest your wiring is probably not up to snuff:

  • The electrical panel is on the porch.  For some reason, this was really popular in our area and many old houses still have the panel on the front porch near the front door.  The panel is outdoors so it's susceptible to wind-driven rain, temperature swings, insects, rodents, and anything else that might be on your porch including someone with less than legal intentions.  Seems like an episode of CSI just waiting to happen.
  •  The electrical panel contains fuses instead of circuit breakers.  This can be okay if it signifies that the house's wiring has not been changed in any way.  However, an electrician with experience in older wiring systems should be consulted to be sure that hi-amp fuses haven't been installed that could cause wires to overheat.
  • There are a mixture of old and new outlets in the house.  When many of old houses were wired, electricity was still a luxury.  There is often just a single outlet and switch in each room.  Today, our lifestyles demand many more outlets for lights, TVs, computers, clocks, this gadget, and that.  Old knob and tube wiring can not be safely grounded or spliced with new wiring so if you see a mixture of outlet types, investigate further.  
  • The wiring looks dangerous.  If the wiring looks dangerous, it probably is.  With the main circuit breaker off, open up one of the outlets and gently pull it away from the wall.  Is it frayed?  Is it even the appropriate kind of wire?  We found one outlet in our project house wired with speaker wire.  Not appropriate.
  • There are bare wires protruding from the wall or ceiling.  Don't touch them!  It's quite likely they are live and you'd rather find out with an amp meter than by shocking yourself, wouldn't you?   
  •  There's charring on the framing near an outlet.  Turn off the circuit breaker.  Do not turn it on again until you get the wiring inspected!
  • The electrical wire servicing your meter hangs low over your house.  It might touch your roof or you could reach out a window and grab it.  This is an electrocution hazard.  Talk to your electrical company about moving the wire.  If it's hanging over the roof, that means it's a danger for someone roofing the house.  If you can reach it out the window, than a child may try.  Get it moved.
  • You don't have any GFCI outlets.  These are code today and important for safety in kitchens, bathrooms, and anywhere else that water and electricity might mix.  They automatically shut the juice off to prevent electrocution on a ground fault.  Add them.
Don't mess with electricity yourself.  Call an electrician and have the wiring inspected and corrected to preserve your investment!

A Credo for Do It Yourself Shows

We watch a fair amount of DIY shows (some would probably say too many), and here's the thing: there are a lot of yahoos out there that take these shows as gospel.  They don't have a clue about how to actually do anything, but they see it on TV and think they can do it too.  If for no reason other than that, it is the responsibility of all DIY shows to do it right:
  • Be a good example.  If you don't work safely and responsibly, how can you expect your viewers to do so?
  • Don't mock the homeowner who got himself in too deep.  You are the expert.  That's why you have the show.  Mocking that one homeowner makes other homeowners feel like they shouldn't ask questions which leads them to more trouble.
  • Use the safety gear you hate.  The safety glasses?  They make you look like a total geek.  The mask?  It hides your luscious lips.  The gloves? They make you seem oh so much less manly.  The ear plugs? What?  USE THEM!  ALWAYS!  If you don't, your viewers won't.  And then you can feel responsible for the lost eyesight from the spraying tile saw, the inhaled fiberglass insulation causing an asthma attack, the mangled fingers during demolition, and the deaf ear from the jack hammer.  Pretend OSHA is looking over your shoulder.  For your newby viewers' sakes.
  • Use the right tool for the project.  No axes for demolition please. That just gives me the heeby jeebies.
  • Get a building permit.  This part is often not shown on DIY shows so many homeowners don't even know they need a building permit for the work they are doing.  That can cause all kinds of problems when the cease and desist orders start flying. 
  • Work with the building inspectors and historic district commissions instead of indicating that they are just there to derail your project.  Building inspectors and historic district commissions are there for a reason: your safety and the integrity of your home and the neighborhood.  Often they will work with you.  If you ask.  Not if you try to power your own idea of code through and expect them to accept it.  Having a good working relationship from the beginning is far better than an adversarial one that begins three quarters of the way through the project.  Make your viewers aware there are building codes and there might be other covenants on the property before the inspectors strike.
  • Salvage what you can.  In our new greener world, don't replace all of the windows, and doors, throw out the old fixtures, wood paneling and trim, or destroy the radiators.  If you really can't reuse them in your project, bring them to an architectural salvage yard or a ReStore.  Someone else can often reuse these things and keep them out of the landfill.  But only if you don't throw sledge hammers at them or shatter them in the dumpster.
  • Make it clear that if you don't have experience, you shouldn't do it at home.  There are certain jobs that should be left to the pros.  There's been a lot of DIY wiring going on on shows lately that makes me cringe.  People are shocking themselves and laughing it off.  They could die.  They could burn their houses down.  If you don't know what you are doing with something as potentially dangerous as electrical wiring, hire an expert!
  • Don't glorify the yahoos who shouldn't be doing it at home by giving them their own shows, it just encourages more yahoos.  'Nuff said.

Check One Task Off the (Long) List!

Not to dwell on (or in!) the attic, but we finished the insulation!!  We'd like to think we did such a great job that the gas company will be paying us this year, but that's probably just a bit optimistic.  It is good to have a clean attic with clean and fluffy insulation to keep our heat in the house.  We've got our plywood laid out up there to store Christmas decorations and such, so we're already using the vast storage space that it is for now.

While we were up there, not only did we have the chance to remove the insulation, but also the old knob and tube wiring and other unused fixtures.  One of our first tasks before we ever moved into the house was to rewire.  So all of the old wiring had been cut, but at that time, the only access to the attic was through a very small hatch into a very dirty space so the knobs and tubes remained up there.  Another removal was what was probably the ballast tank for the radiator system.  It's still up there because it's too big to get down, but also because it's pretty cool with all of the rivets that hold it together.  It's a great design piece that we'll find some use for.

We were hoping to find a million dollars hidden in the attic.  No such luck, but we did find a few interesting things that we'll incorporate into a "museum" case in the wall when we finish the space.  Our most recent finds were an envelope postmarked December 1913 - the year the house was built and a christening dress.  The dress was in perfect shape, just dirty from being under the insulation.  It's nothing fancy, but does have some embroidery on the yoke.  I'm thinking we could come up with a gothic novel about how the dress found its way up there, but then I might get a little nervous when I hear normal creaks from above!
