When you need roof repairs, make sure to work only with a roofing professional who can fix the root cause of the leak, and not only a quick fix, temporary solution to your problem.
Having said that, here are the most common causes of roof water damage, and how you can fix them:
• Valley Damage – The inside angle of your roof where 2 faces meet is called a valley. It is a weak area in the roof, and rainwater can be channeled through it. You can prevent issues with your roof valleys by having a professional roofer install an open valley or closed-cut style roof.
• Flashing Malfunction – Flashing is the thin sheet of metal installed at specific roof points such as the point where the roof and a vertical wall meet. Although it may be counter-intuitive, flashing can sometimes be overly secure.
Steel expands and shrinks, depending on the temperature. If the flashing is nailed to the wall and the roof, deformation may result. This will then leave some space for water to get in. When warped, your flashing must be replaced, and not merely repaired.
• Roof Feature – Anything that penetrates the roof decking is known as a roof feature. Examples are chimneys, vents, skylights, as well as anything that lets light or air to travel on the roof from side to side. These areas of the roof are vulnerable as they directly lead into the home. Water can get in through them. To keep water out, flashing must be installed properly in these areas.
• Damaged Shingles – In most cases, a roof leak arising from damaged shingles happen either right after installation or after the shingles have been installed on the roof for a very long time.
When they happen immediately, problems are often because of improper installation or manufacturing defects. The problem can be easily fixed by an experienced roofer.
On the other hand, if the shingles have long been on the roof, and they now look ripped, curled, thin, or are starting to fall off, the problem may be due to the effects of normal wear and tear. It may now be the right time to replace them. If you opt not to replace them, leaks may start to develop in different parts of your roof. Thus, complete replacement may be the better option.
Roof water damage can be messy and expensive to fix, especially if ignored and allowed to go on for a long time. A lot of problems can be avoided if the problems are addressed as soon as they are detected. Through regular roof maintenance, early signs of wear and tear that can lead to future problems can be spotted early.
