Four Common Problematic Roof Areas To Watch Out For

Some parts of the roof experience problems more commonly than others. You need to pay more attention to these problem areas so that you can take care of any teething issues before they become full-blown problems. Here are some of these problematic areas:

Roof Valleys

Common in complex roof systems, roof valleys are V-shaped sections of the roof where two sections of the roof meet. There are three main reasons why roof valleys tend to experience more problems than other sections of the roof. First, the roof valleys are joints and any roof joint will always be weaker than continuous sections of the roof. Secondly, the most water that falls on the roof end up in the valleys before flowing into the gutters; this increase the risk of corrosion and water damage on the valleys. Lastly, most debris on the roof, such as leaves and dirt, will also end up in the valleys first. 

Roof Penetrations  

A roof penetration is anything that protrudes from the surface of the roof. Examples of roof penetrations include chimneys, communication antennas, vents, and rooftop HVAC units, among other things. Roof penetrations are dangerous because:

  • They break the continuity of the roof's surface
  • They create weak points on the roof
  • Interfere with roof drainage

It is easier, for example, for a leak to occur around a roof penetration than on other sections of the roof.

Roof Flashing

A roof flashing is a piece of metal used to create a water-resistant barrier on the roof. Flashing is commonly used to waterproof roof joints such as the area between a roof penetration and the rest of the roof. It shouldn't be surprising that roof flashing is also problematic since, by their nature, they are installed on areas that are already weak. Flashing may get torn during a storm accident or it may lose its waterproofing ability over time due to normal wear and tear.

Roof Gutters

The last examples of problematic roof areas are the gutters. Gutters are probably problematic because all roof debris, water, and lose materials end up in the gutter due to gravity. Fallen tree leaves, water from melting snow, and windblown debris on the roof, for example, eventually end up in the gutter. This increases the risk of gutter misalignment, gutter clogging, and gutter corrosion, and gutter detachment — all of which interferes with the gutters function.  

Being careful with how you get your roof installed and repaired can help you avoid most of these issues from the start. Find a roof installer like Premier Roofing Co that will do a good job and avoid putting in any problem areas.
