5V Metal Roof

We recently replaced a section of metal roofing in North Raleigh.  The recent rains this summer in the Triangle produced several leaks in an old 5V metal roof.  Due to the roof's age we determined the best approach was to replace it.

The original roof slope was comprised of a 7' and 4' section, transitioning into a lower 2/12 pitch slope.  Most of the leaks were in the transition. After removing the metal panels, we installed "ice and water shield" along the 30' horizontal transition.  Instead of replacing the metal panels the same way, we decided to use a 12' panel, folded at the transition, extending 12" into the lower panel,  providing seamless, water-tight protection for the client.

Here is a photo of the completed project.

A Roof Replacement May Require Removal and Reinstallation of Gutter Protection

When considering installing a gutter guard, which is installed under a row of shingles, the inspection of the roof is a necessary component.  If the shingles are brittle or curling, or if the homeowner knows that their 15-year shingles are now 20 years old, serious consideration should be given to replacing the roof  first.  This is an important consideration to avoid a removal and re-installation of gutter guards in the near future.

Gutter covers have to be taken off before a roof is replaced. In many instances,  in order to not void the warranty, you must have the installing company do the removal and re-installation. Most companies will not be comfortable with warranting other company’s re-installation of their gutter guards.  It is not uncommon for a roofing contractor to volunteer with the best of intentions to remove and re-install the gutter protection for free.  Then when the systems fails and the homeowner calls the original installing company, they find out that the system was reinstalled improperly.  In some cases, the system was damaged and unusable due to improper removal and re-installation. We see this all too often.

There usually is a charge for this service.  The removal and subsequent installation involves the gutter installation crew to come out twice, once for the removal and again for the re-installation.  The installing company incurs set up fees twice for each service. 

Sometimes material has to be replaced.  Gutter covers don’t always go back on properly, once they are removed, especially if you are dealing with an inexperienced crew or a crew which has never worked with that type of guard.  Sometimes, the color of the roof is changed, so the color of the gutter protection is changed as well requiring all of the panels to be replaced.

There is usually a nominal fee for the removal and re-installation.  A gutter cover installer or contractor has already made a profit on the original installation and usually just covers the cost on materials and labor.  Some gutter cover installer or contractors that also do roofing will perform the service at no charge as long as you purchase your new roof from them in the future.  This is a good situation if you really need gutter protection, and your roof still has a few years of life left to it.

You can avoid an unpleasant surprise in the future if you consider the condition of your roof before purchasing a gutter protection.  You need to plan out what is going to happen when you eventually replace your roof to avoid extra expense or loss of warranty.

Chimney Cricket not Jiminy Cricket Installation

There are time when we receive calls at Allen and Deans about leaking chimneys.  In most instances the metal flashing has rusted or corroded allowing water to enter.  However, there are times when the chimney is positioned at the eave (bottom of the roof) and there is no cricket.  Rain water flowing down the roof hits the back of the chimney.  Over a long period of time, water will begin to infiltrate or penetrate in or around the metal flashing, which is the last line of defense for the chimney.  This is usually the case in older homes here in Raleigh.

Here is a photo of a brick chimney we worked on recently. Note how wide the chimney is.  It almost serves as a dam for water as the water runs directly into the back wall.

Add some pine straw or leaves behind the chimney and you can easily see how water and moisture can stay behind the chimney and not flow away to the sides and off the roof.

A cricket is nothing more than a wooden structure consisting of 2"x4" lumber for the base structure and 7/16" OSB for the angled platform.

The last photo is the cricket completed with "ice and water shield", new metal step and counter flashing and new, 3-tab, self-sealing shingles.

Now when it rains, the water is safely directed to either the right side or the left of the chimney falling harmlessly into the gutters below.

Bradford Creek Golf Course

We recently had the opportunity to work with The Parks and Recreation Department of The City of Greenville..  The clubhouse roof at Bradford Creek Golf Course was severely damaged as a result of Hurricane Irene, earlier this summer.

The project featured a CertainTeed LandMark 30 architectural shingle.

Here is a photo prior to the start of the project.

Here are some photos after the roof was installed.

Chimney Flashing Repair

We recently received a request to repair a leaking chimney. We could have simply caulked the perimeter of the counter flashing and "called it a day". However, it has been my experience that caulking a chimney does not provide a long term solution. In many cases, it does not provide ANY solution at all.

We took a much different approach to solving the flashing leak. We removed all the shingles, felt and metal flashing. Upon cleaning the perimeter very thoroughly,
we installed a weather barrier or generically referred to as "ice and water shield" around the perimeter as you can see below.

You can see how we installed the "ice and water" on the wall and then folded it so it laid flat on the roof deck on all 4 sides of the chimney.

We then installed new step flashing, which is covered up by the new, black counter (outside) flashing.

Once the counter flashing has been caulked, we then finished the repair by installing shingles along all 4 sides of the chimney.

This flashing process will provide problem and leak free service for many years to come.

But wait a minute. Something doesn't look right here. Can you tell what is wrong in the last couple of photos? Look carefully. Do you see it?

You are right. It is the shingles. They don't match, do they? The shingles on the back slope are regular 3-tab shingles. The front shingles are a CertainTeed Horizon shingle, which unfortunately were discontinued a couple of years ago. In order to make the front slope of the roof (look) presentable, we kept and in some instances "reused" the Horizon shingles from the back roof slope whenever possible. We simply installed the new shingles on the back slope where they would not be as noticeable or visible.

Pipe Boots: A Small Item Which can Create LARGE Roof Problems

There are several items on any given roof. One of the smallest items are pipe boots or pipe collars. These are the black rubber and PVC units you see on the bottom of those white (vent)pipes protruding from your roof. Their purpose is to prevent water from penetrating through the hole in the roof deck.

As you can see here, this boot is severely cracked. As a result, every time there is rain, the attic below is getting wet. Left unchecked, penetrating rain water will begin to rot the plywood or OSB (Orient Strand Board)decking creating a more serious leak issue.

Generally the pipe boots will start to deteriorate in 7-10 years after they are installed. Certainly their exposure to the sun will increase the deterioration process. The seal on top becomes brittle and begins to crack.

In a sense, pipe boot failure is much like brake failure on your car. Rarely, do the brakes go bad on both wheels simultaneously. The same is true with pipe boots. Not every boot on your roof will fail at the same time. But with some time, all the other boots will begin to fail as well.

However, just like brakes, your mechanic will recommend replacing both or all brakes simultaneously. It is wise to replace all pipe boots at once. By doing so, you will have the satisfaction knowing your roof will be "water-tight" at those vent pipe (boot) penetrations.

If you have a pair of binoculars, why not have a look at the pipe boots on your roof? If you do not see any indication of cracking you can be sure they are doing their job. If there is evidence you should contact you roof contractor to have the boots removed and replaced.

Roof Leaks in Your Attic

The Good News here in the Triangle is we finally got our rain.
The Bad News is it has probably uncovered some roof leaks in our
homes.

This is an outstanding time to go into your attic and inspect the roof
sheathing for leaks. Take a flashlight with you so you can better see
into those dark nooks otherwise known as rafter bays.

Carefully scan the plywood or OSB sheathing with your flashlight. You
are looking for "dark" stains or even dripping water. The darker and
wetter the stain, the longer that area has been leaking. Check very
carefully around penetrations through the roof, such as, chimney, white
PVC vent pipes or bathroom or kitchen exhaust vents. Those are most
the likely areas to have problems.

Hopefully you do not find anything concerning in your roof. However,
if you do, you should contact a professional to evaluate the situation in
greater detail.
