Charcoal Timberline shingle roof with standing seam copper porch

Tuesday, April 26th, 2011

There are many houses in Arlington and Alexandria that are virtually identical to this one, most were built  50 to 70 years ago; this house was probably on its third or fourth roof. As you can see, the existing light gray shingles are old and worn and are at the end of their life. The Owner of this house will soon outgrow it, so it was important to install a new roof that will protect the property but will also add some curb appeal when the day comes to sell it and move on.

Here you can see the pitted and cracked shingles from the side porch.

First: Off with the old roof; once the old shingles are removed we inspect the roof deck for rotted or split boards.  Generally these houses are really solid, most of them have old growth 1×6 pine or sometime oak roof decks; the density of the boards resists rot even when the roof is neglected for years. This house needed a few deck boards replaced because of cracking and a little warping; so far these boards have had at least 18,000 roofing nails driven in and pulled out of them and they look like they can take 18,000 more.

When replacing a roof we have to act as if it’s going to rain any minute-even with bright blue skies, we work quickly to cover the house from rain. That’s why we focused on the main house roof first before working on the lower porch roofs.

The main house is covered first

Once the main house was waterproof I started on the lower porch, to add some curb appeal the Owner opted for a standing seam copper roof on the small front porch. When installing an accent roof like this symmetry and scale are of the utmost importance. I made these 16 oz copper panels in the shop, they divide the roof into five equal segments; if you look around you’ll see metal roofs that were installed from one end of the house to the other, without evenly dividing the roof you wind up with a full size panel on the left and a little skinny panel on the right. Asymmetrical layout can look ridiculous or it can be just a little off , bothering anyone looking at it-even if they don’t know why.

To keep the roof as compact and graceful as possible I turned the standing seam panels up the wall in one continuous seam, the technique takes time and practice but it looks perfect. The panel is never cut into, I fold pleats into the copper and then double lock the seams for a completely waterproof joint that requires no sealant or solder; its taken years to perfect this technique and no I won’t show you how to do it.

At the end of one very long day we have a finished beautiful roof.

Shingle roof repair or replacement? What’s best?

Wednesday, March 9th, 2011

This roof took a beating in high winds. When looking over the necessary repairs it became obvious that replacing the missing and damaged shingles would make the roof look terrible. The roof as you see it below is around 15 years old, and like most things left outside for 15 years, it has a good amount of algae and dirt accumulated on it. Installing new, clean shingles into a dirty roof would look terrible.

The homeowner decided she didn’t want to see the front of her house looking even worse than it does with the missing shingles. The one new shingle from a previous repair (you can see it above the chimney) is glaringly obvious, based upon the age and probable plummet in curb appeal, my client decided to replace the roof.

Step one: Tear off. After the old shingles were removed we replaced some rotted and cracked pieces of roof decking.

Step two: We installed new drip edge and waterproof underlayment.

Step three: We install new GAF Timberline shingles in Pewter Gray. We also installed new copper flashings on the chimney, new pipe collars on the plumbing vents, a new ridge vent and ridge caps. We also reset the satellite dish, cleaned and re nailed the gutters and flushed out the downspouts.

Step four: Final clean up, we sweep the yard, the flower beds and the driveway with a magnetic nail bar (yellow handled bar) to pick up any bits of metal left behind. My goal is to leave nothing but a beautiful new roof behind.

There are about 165 more steps than what I’ve shown you here; but I’ve found that most homeowners don’t want to read about psi settings on the compressor or flashing techniques. However, if you want to hire a roofer who cares about compressor settings, european flashing techniques and making your house beautiful then you should call me; I promise I won’t bore you with all the details (unless you want me to).

From metal to membrane- low slope roof replacement

Monday, March 7th, 2011

This is standing seam tin roof, probably around 40 years old.  During high winds the eave edge of the roof was peeled back and flipped over on itself; the owner did his best to push it back and laid bricks across it to hold it down. When the panels flipped over it split the metal along the seams, there was really no repair option, the roof needed to be replaced.

The majority of the roof is a charcoal asphalt shingle, this area was the only one with metal. This portion of the roof has a very low slope, too low to replace the metal roof with shingles. This area is also invisible from the ground so there really wasn’t any reason to install another metal roof. My client chose TPO membrane, TPO is a bright white material that will perform perfectly in this application.

The pictures below will take you step by step through the job, click on any to enlarge.

We removed all of the old metal roofing and found that the roof decking was all in great shape. The panels you see being laid out is 1″ thick polyisocyanurate rigid insulation board; it has two functions, first it protects the roofing membrane from the rough bumpy roof deck and it also provides good R-value.

polyisocyanurate insulation board

We fastened the insulation board with plates and screws, the round silver plates act almost like washers, giving more surface area for the center screw to clamp the insulation tightly to the roof.

TPO membrane comes in a variety of widths to suit most common applications. To keep seams to a minimum we chose a 10′ x 100′ roll of TPO; it is secured to the roof with screw and seam plates; these are smaller than the insulation plates but perform the exact same function.

The second course of TPO is installed  and the overlap is welded with a hot air welder; once welded the seam is as strong as the field of the membrane. This seam requires no glue, no caulk or sealant and no maintenance.

The edges of the roof are secured with drip edge, it’s an L shaped piece of painted aluminum that waterproofs the roof edge and secures the membrane at the perimeter. You can also see a TPO pipe flashing installed and welded to the membrane.

After the drip edge is installed we cover the fasteners with white TPO cover flashing. This entire roof system is designed to overlap and enclose all exposed fasteners, this will make a roof virtually maintenance free.

We use matching shingle ridge caps at the peak of the roof, this will look perfect from the street.

All done; this roof will provide good service for a least 20 years with minimal maintenance from the owner. The bright white membrane surface and insulation board will also keep the upper floor cooler in the summer and a little bit warmer in the winter.

Wind damaged roofs

Thursday, December 30th, 2010

Perhaps you’ve just returned from your holiday to find some roof shingles in your yard; they might be from your roof or they could be from a house on another block.

Northern Virginia has had some incredibly high winds over the past week, some in excess of 80 mph. The same winds that knock down trees and power lines can send a few of your roof shingles sailing away as well; don’t panic its usually an easy fix.

If you find a few shingle tabs in your yard step back a bit and look at the color; does it match your roof ? Look up at the roof, especially at the ridge line; see any bumps that weren’t there before?  Ridge vents and furnace flues can sometimes get loose in high winds, they should all look straight.

This furnace flue got pushed over in the wind; you can see how the corner of the flashing was pulled up.

Wind damaged shingles Wind reaches its highest speed at the edges of a solid object (like an airplane wing); the most common place for shingles to be damaged is at the ridge/peak of the roof.

Sometimes the missing shingles can be hard to see.

This shingle tab bent back and over in the wind; asphalt shingles aren’t flexible, they only bend back once, the second time a shingle bends back it cracks off and flies away.

If you suspect that your roof has taken a beating in the winds you can call us anytime, we will go up  and inspect for damage. We will take pictures of the damage (if any) and let you know the level of urgency for any repairs. Call us now 703-299-8888.

Roof in a Can

Wednesday, October 7th, 2009

This is one of those classic examples of a “Roof in a Can”.

Roof in a Can is a term we came up with when describing a repair job we’ve seen; it’s when the person working on the roof can’t figure out the right way to do something so he just squirts caulk over the problem. I have a collection of these pics somewhere, I’ll put them up someday.

Before:

Leaking pipe collar and caulk

These plumbing vents are really close together; too close for the installer to use two pipe collars. The pipe collar is installed on the pipe on the left, the pipe on the right got the Roof in a Can treatment.

I would love to know how the person decided which pipe got the collar and which one got the caulk. Flip a coin? Did he ask a coworker? Did he think the larger pipe was mocking him?  Maybe he just wanted the smaller pipe to have the collar, pulling for the underdog on the roof.

copper pipe flashing

This took me about thirty minutes; it’s made out of 16oz copper and will last for the next three roofs. No caulk to dry out and crack, just copper and lead solder. Solid.

There they stand ready to face the weather again. Both pipes treated with practical dignity; flashed with copper and installed with pride.

Caulk is not a roof and caulk doesn’t last, don’t let someone “repair” your roof with a caulking gun.

If you have leaking pipes on your roof give us a call.
