Leaking roof valley strategy


If you have a roof valley in your home, then you may find that your lead valley starts to leak, or even to allow water to run onto the ceiling of the floor below. If you find that this is a problem, then you will need to repair your roof valley before anything serious happens, such as plaster loss, or even major water damage. A lead valley is a particularly difficult item to dispose of, as lead is toxic, and so a repair may involve simply patching up your lead roofing. Following some basic rules will give you a quick and simple way to repair your lead valley roof.

Step 1 - Find the Cause

Find the place where that leak is coming from. Many roof valley leaks are caused by roofing nails that have been poorly placed, and are acting as a dripper, feeding water through from the roof above. The roofing nails are fine so long as the lead of the roof valley is intact, but once it starts to crack or fracture due to water pressure, corrosion or other damage, the nail...

Roof valleys are a frequent source of leaks in older houses. Installation procedures differ depending on the roof type and materials used. We will look here at the basic installation of an open lead lined roof valley.

A roof valley is basically a gutter set between two meeting pitched roofs. Depending on the roof area it serves, the valley is the exit point for a large volume of water so extreme care should be taken with installation. If the roof has been leaking for a while or if there are any signs of rot, you will need to start by replacing the valley boards. Lead sheet is not self supporting and should be placed on treated roofing boards of sufficient strength to hold a large person. (Most roofing contractors are big guys!) Fit boards of sufficient width to accommodate the lead plus 100mm either side. This will give you something to nail the roofing batons to.

The top of the valley boards should be at the same level as the top of the roof rafters. If you lay the...

Waiting for repairs to pop up and make themselves visible to you is a gamble. A huge gamble. You can then choose to patch the problem, and if it is truly minor, you’re good to go. If it is major, then the patch is just buying time. Instead of years, think of it as months.

If you can't see any telltale flow marks, and since the stain is fairly small, look at the underside of the roof for 'shiners.' A shiner is a nail that missed the framing member, in this case when the carpenter nailed the roof sheathing to the rafters. Moisture that escapes into the cold attic from the rooms below often condenses on cold nails. Sometimes you can spot this if you climb up into your attic on a cold night.

Valley leaks:

Leaks in or near valleys are some of the most difficult leaks to track down and repair. Experience and understanding of the leaks frequency can help determine if the valley is leaking or if the roofing above the valley is leaking (and then showing at the valley). When roofing a home we recommend a closed valley system where the tiles overlap at the valley with ice/water shield underlayment underneath for added protection. As water runs down your main roof and picks up speed when it comes to a closed valley, the water runs onto the adjacent underlying roof. If 2 roof pitches are equal in pitch and size the water will cancel out at the valley. If wind blows water under the overlapping roof at the seam, gravity will eventually pull water back down (as long as the valley is shingled properly). The visual inspection by a professional roofer includes knowing where all factory seams are to find possible seam on seam mistakes and determine where shingles stop beyond...

I have a corrugated metal roof. There is a leak at the eave near the end of the valley. I've pulled off one of the soffit panels and see that water is leaking in that area. I've run a garden hose over the valley area and can't seem to find where the leak is at. I'm sending a picture of the valley. The leak occurs underneath the area at the end of the valley. I can also send a second picture of the leak under the eave. Thanks, James

Lead valleys are one of the oldest and most durable forms of roof valley construction. A well fitted roof valley constructed from lead sheet will outlast all other roofing materials. If your lead valley needs replacing, chances are it is either over 70 years old or it was installed incorrectly in the first place. Poor installation is the number one cause most roof valleys fail. For information on roof valley replacement and repairs, please view our website.

Valley boards

The valley boards should be strong enough to support the valley and the weight of a large person to allow future maintenance. (minimum 18mm ply) The boards should be treated against rot and insect manifestation. If you are replacing a roof valley and you intend to re-use the origional boards, make sure the boards are free from old nails.

It’s important to take care of your roof just like it takes care of you and your loved ones. As such, you need to be aware of what constitutes the entire roof and ensure that every part is in good working condition. Failure to do this may mean that you pay attention to some areas of the roof and leave others out, and this could leave your roof vulnerable to damage in one way or another.

One of the frequently overlooked areas of the roof is the roof valley. The fact that it is a part of the roof where an intersection is formed makes it very sensitive and prone to damage. Its function also exposes it to various dangers. If you are wondering what a roof valley is, the following article gives an in-depth understanding of the nature and function of a roof valley:

Though roof valleys are common leak sites on shingle roofs, it’s typically fairly easy to fix these problems with a little know-how.

Roof valleys are channels designed to drain runoff water, and like any other part of your roof, they can degrade over time with exposure to the elements. In other cases, water can become trapped under shingles which have been overlaid to create the valley trough.

In either situation, the leaking roof valley can be fixed by removing affected shingles and structural elements and upgrading your roof’s flashing. A flashing is a transitional roofing material that connects the roof material to some other building material or to another part of the roof. And flashing is behind most roof leaks.

We have been in the roofing business for 25 years. We may not know how to spell, but roofing we know best.

Most roofers know how to install shingles, but many have no clue how to do a valley. The materials they use in valleys are inferior. We use rubber roof membranes. Because of our experience in flat roofs we use better materials and techniques.

In the following pictures, we show the process of repairing a valley area. When a valley is flat like this one in the image, it is more problematic. Water like to follow the valley to the edge and flow back under the valley.

Valley areas are prone to leak due to the lack of using proper materials. Most roofers that do shingles will use a heavy base paper instead of a rubber...

Roof Repair, Infrared

I am really impressed with the prompt response, great professionalism and a job well done on my roof repair today.

My parent's house has a pretty bad leak that has been going for a few years. Because of money and other issues with the house I need to try do an improvement myself if at all possible. Getting a new roof (or house, since everything else is outdated/has an issue) may be possible down the line but not right now.

One thing slightly in my favor is this is in San Diego so it rains infrequently.

I have included some pictures. In the last you can see where I pulled some of the ceiling down where it was mostly soft/mushy. Asbestos test was negative.

Estimators have suggested the issue is definitely with the valley and one of them recommended I could install flashing in/along/under (not sure what he meant) the valley to improve the situation. I purchased a roll of aluminum flashing. I am not clear on exactly where to put it though.

The examples I see on youtube when I search 'roof...

A leaking roof caused by roof penetrations is a problem for roofers and their customers. It can result in hours of lost productivity and customer disappointment. This roofer’s problem has been around since cavemen first thought it a good idea to let the smoke out of their shelter but not let the rain in.

Luckily there is a simple trick, not taught at technical colleges, which can help roofers avoid a common error when dealing with roof leaks caused by roof penetrations.

The problem for many plumbers new to metal roofing, is the seemingly simple process of installing a Dektite® flashing to seal a roof penetration from a slow combustion heater flue or plumbers vent pipe.

A Dektite®, also known as a pipe boot, is a rubber cone with an aluminium backed flange strip that attaches to the roof and elegantly solves another common roofer’s problem: how to seal the penetration of a roof by a round pipe or post.

Lots of things can go wrong with roofs: bad flashing can cause leaks, a poorly designed valley can turn into a slow-moving glacier, and misplaced gutters can do more harm than good. Experienced roofers see a lot of stupid roofs.

Soon after I dropped out of college in 1974, I got my first construction job. I was hired by Edward J. Thornton Roofing Company in Newtonville, Massachusetts. The company paid me $3.50 an hour. For the next 12 months, I installed countless bundles of asphalt shingles and mopped acres of tar-and-gravel roofs with hot asphalt. Every now and then, I also helped Ed, the company’s sheet-metal worker, to install copper valleys and copper-lined cedar gutters on slate roofs.

Most of the time, I was installing asphalt shingles, back in the days before nail guns and portable compressors. We used heavy wooden extension ladders. My staging consisted of 2x12 planks laid on hardwood shingle brackets; each bracket was secured to the roof with three 16d...
