Dead valleys may apply to both the old houses and the new architectural designs. Other contemporary houses have elaborate roof lines that are pretty but inadvertently they form drainage bottlenecks. In the case where several slopes of roofs are empty in a small area, the water falls on a single tight area having no place to go. Knowing what dead valleys are and what are Dead Valley Roof Solutions, how can they save you the trouble of protecting your house, preventing leaks and putting your roof into action as it is meant to.
Each roof is of a different form, gradient and construction. Although the majority of these design characteristics are to enhance drainage and guide the water in the right direction and out of your house, there are areas that need additional care. Such a space is the dead valley -a place on the roof where the water finds it difficult to drain.
People tend to believe that a dead valley is trouble waiting, but that is not necessarily the case. Even a dead valley, properly designed and constructed, can be safely used, at any rate over years. Only in case of poor design, aging of the roof, or unsuitable materials used, problems occur.
Two most significant components of a roof are ridges and valleys. The ridges are the most elevated and represent the intersection of two roof planes. The lower points are known as valleys and this is where roof planes intersect each other to direct water downwards. Valleys naturally gather leaves, needles and debris due to their form.
Unless constructed properly, or the rubble swept up, water remains longer than it ought. A valley ceases to drain successfully and the water starts to stagnate or flood with stagnant water, then it becomes a dead valley according to roofers.
What Are Dead Valley Roofs?
The dead valley occurs when water in the various roof areas flows to a single restricted area where it can drain. In most instances, it is a design decision especially in houses with steep roofs or where a roof plane is attached to a wall which is vertical. Rather than flowing into a gutter with smooth flow, water flows into a narrow space, a flat space or a narrow angle of motion.
A typical example of dead valley is that where a roof is run up to an adjoining side of a taller wall. Water flows down the roof, strikes the wall and gets stuck in a minute wedge-shaped area. This means that the water does not drain but instead it remains stagnant without being flashed, waterproofed, or corrected in terms of slope. In other situations, two valleys can combine at an angle that retards the movement of the water and hence it will start stagnating and saturating the roofing material.
It is not only the standing water that is the problem of dead valleys, but the moisture, debris, shade, and limited airflow. Leaves, pine needles and small branches are likely to accumulate in these places. The accumulation of debris causes the water pools to continue extending, forming the ideal condition where the shingles rot and the wood decays. With time, the water may leak through the layers of the roof and get to the plywood decking. Once that occurs, it means that leaks will occur, although the appearance of shingles may be okay at the surface.
Complications with dead valleys are another aspect that makes them a bother since people who own homes usually fail to see them. The damage goes on silently since most of them are often seated in a location that cannot be easily spotted on the ground, until they show their symptoms on the interiors. When your ceiling stains or when the sheetrock on your wall starts to crack, the water probably has been getting into your house for a long time.
Poor craftsmanship is not necessarily the cause of dead valleys. There are other times when the architecture merely forms inevitable low points. Of interest is the manner in which these areas are constructed, strengthened, and sustained.
What Dead Valleys Mean to Your Home?
There are numerous dangers that dead valleys can present to your home unless it is done properly. Being the largest factor of threat to the long-term health of a roof, any stagnant water area is a weak point. Even small pools may damage wooden framing and cause growth of mould and are likely to weaken shingles gradually.
Shingle deterioration is one of the first signs of the dead valley problem. Shingles become soft or brittle when they have been sitting too long and losing their granules. This in the long run causes moisture to leak under and get to the underlayment. In case the problem is not addressed, the water finally reaches the plywood decking. After the decking has accumulated sufficient moisture it starts to rot, warp or sag.
The interior symptoms can consist of the brown ceiling stains, peeling paint, or a wet drywall around the location of dead valley. A lot of homeowners can be shocked when a roofer informs them that the root cause is outside when the roof appears normal when viewed using the ground. The hidden damage formed by dead valleys usually manifests itself only when the situation proves more serious.
The other hazard is the accumulation of debris. The dead valleys themselves are habitats of the leaves, pine needles, and dirt. When organic material decomposes, it has a greater moisture content forming a thick, wet layer on the roof. This hastens the deterioration of the shingles, and exposes the roof further to the heavy rain or snow.
Dead Valley Roof Solutions
The positive thing is that it is possible to repair, reinforce, and redesign dead valleys to work safely. The appropriate remedy lies in the extent of the problem, the type of set up of your house, and the kind of materials already employed on the roof. A qualified roofing company like the Northwest knows the way water acts on complicated roofs and how effectively to fix such problem areas.
In case of simple dead valley issues, the process of Dead Valley Roof Solutions and repairing it will be to take off the damaged shingles and properly clean the area. After clearing the material, the roofer checks plywood and structure around it. Learn how to protect your damage roof.
In case the decking has rot or it is affected by moisture, it has to be changed first before any further work is done. The roofer then uses a waterproof cover on top of the plywood as soon as it is rejuvenated by adding wood back to the wood. This membrane is a covering that the water can not soak into the wood even when it accumulates over it.
Once the membrane is installed, application of new underlayment and shingles by the roofer is done. When properly done, it results in a smooth surface which facilitates water to slide off easily and safeguards the building during rainy seasons.
More materials might be necessary in more complicated dead valley scenarios. The roofer can also use metal flashing that will divert the water into a managed channel. Flashing provides a long lasting groove that assists in the water moving through the gutter rapidly rather than languishing on the roof.
In the case of extremely poor drainage areas, one can use modern roofing materials, such as TPO (thermoplastic polyolefin) or special waterproofing membranes. These products are engineered to have a very long life span when exposed to moisture hence are suitable in roofs with very low slope or which experience continuous pooling problems. When fitted, they also do not allow water to stay in the roofing system and ensure that the area remains dry over a number of years.
Why is Dead Valley Repairs not a Do-It-Yourself Project?
The dead valley repairs involve expertise in roof structure, roof waterproofing materials, slope management and drainage design. It is not a safe action to get up to a roof using the wrong tools or little experience and doing the wrong part may make the situation worse. The point is that many homeowners attempt to clean up a dead valley or do it themselves only to find out that some moisture was lurking under it and damaging the area.
As a Northwest Roof Maintenance Inc professional roofer, someone knows the flow of water over every section of your roof. They are aware of the most likely areas of leaks, the distance to which the moisture can have moved, and the material that is necessary to cover the area efficiently. Dead valleys are risky areas, and thus, they need to be fixed using durable products and installation.
The Importance of Frequent Roof Inspections
The problem is that most homeowners do not realize that there is a leak in the dead valley until the leak causes damage to the interior of a home. This is the reason why it is necessary to call in annual roof inspections. We suggest that one check up of storm damage, loss of the granules, loose shingles, accumulation of debris and early indication of dead valley problem should be done annually.

FAQs
1. How do I know if my roof has a dead valley?
Dead valleys will usually conceal themselves in corners, the back of walls or in low-lying areas of the roof. When you observe piled debris, water accumulation or inside leaks towards roof walls facing walls, you are likely to have a dead valley. It can best be confirmed by a professional inspection.
2. Can a dead valley be redesigned or permanently fixed?
Yes. The slopes can be rebuilt by roofers, metals flashing installed, waterproof membranes or the drainage path redesigned to allow water to flow properly. The permanent solutions would be determined by the construction of your roof and the intensity of the issue.
3. How soon should a dead valley repair be done?
As quickly as possible. Damage caused by moisture propagates without noise. The more time the water will take in a dead valley, the higher will be the possibility to encounter wood rot, development of molds, or costly structural maintenance.
