St Louis Roofing: Article About Major Causes Of Roofing Leaks
There is no such thing as an insignificant roofing leak. What appears to be a tiny leak is simply the precursor to more significant damage to the roof if the problem is not addressed in a timely fashion. Once the roof has sprung a leak, there will be a need to speak with a St Louis roofing expert to determine the best course of action. An ounce of prevention is worth a pound of cure. Understanding the primary causes for leaks will allow homeowners to take preventative measures that can reduce the risk of leaks in the first place.
There are some common causes of roof leaks, and understanding what these causes are will help eliminate, or at least lower, the risk of experiencing roofing leaks. A cracked flashing is a common cause of leaks. The flashings are thin pieces of metal that are placed immediately under the shingles at the joints of the roof. These pieces of metal are there to create a waterproof barrier. These barriers can be either exposed or concealed, but they perform the same task. The flashings normally become cracked because the tar that is used by roofers to seal the flashings together can potentially corrode as time progresses. The risk of corrosion is exacerbated by exposure to certain elements, such as wind and rain. Having the roof periodically inspected can help guard against this type of erosion, and guard against the development of leaks.
Broken or busted shingles will also lead to leaks.

The good thing about this particular cause is that it is easy to spot. Because shingles serve as the exterior of the roof's structure, it is easy to visually detect abnormal wear and tear. When shingles are broken, a person will be able to see a change in the color of the roof. Another sign of damaged shingles is finding pieces of shingles laying on the ground. Heavy rains and high winds are generally the culprit when it comes to damaged shingles. The good news is that a qualified roofer can replace the damaged shingles in a relatively short period of time.
Improperly sealed valleys can lead to leaks in the roof too. Valleys are where two different planes of the roof merge, and when the connected planes are not properly sealed, water can seep through, especially considering that most roofs are sloped and water will be running down these slopes to the valleys. There are many reasons for the break in the valley seals. It could be that the sealing was not done properly during the initial roofing job, or the sealing product could have been substandard. It is also possible that the seal could have cracked as someone on the roof inadvertently stepped on it. Detecting a poorly sealed valley will be a bit more difficult, but it can be detected during a routine roofing inspection, which homeowners should have done periodically.
There are a number of additional causes of roofing leaks; however, all of these causes can be mitigated by having a qualified roofing professional conduct a periodic examination of the roof on a regular basis.
