Roof Valley

Installation or Repair, VA

 Look around at the rooftops in the neighborhood where you live. It’s highly likely that you will see roofs with various shapes and angles. The shape of a roof gives a house a unique appearance, adds to its aesthetics and increases the value of the home. For a homeowner in Virginia, an interesting roof is an important addition to the appearance of your home, but it also presents a challenge when it comes to a roof repair. The roof valleys are the low places on your roof where various sloped sections of the roof meet and these areas are very susceptible to the development of a leak.

 The problem can start during installation of the metal flashing used to cover the seam. If the roofing nails are placed too close to the seam this puts pressure on the shingles, causing them to crack. Not using enough nails allows the wind to force up the flashing and loosen the few nails present. Obviously, flashing that is too short or not wide enough will allow rain to seep into the roof valley joint.

 The UV rays from the sun and the other natural elements take a toll on the entire roof, including the flashing covering the seams. Over time the adhesives used to seal the flashing and keep the roof watertight shrink and crack, causing the metal strip to lift and buckle.

 This part of the roof, since it is lower, tends to be the gathering place for blown off leaves and other organic debris. It’s really important to keep your roof valleys clear of organic material. As it decomposes, it has a corrosive effect on the flashing, creating pinholes that allow water to trickle down into the seam and follow a path into the attic.

 The slopes on your roof are designed to whisk away the rainwater and direct it downward toward the gutters. The valleys fill with rushing torrents of water moving with speed and force during a storm. The tiniest gap between the flashing and the shingles acts like an open door, inviting the water to leak through the roof deck.

 We recommend you call us today to schedule a free roof inspection for your Northern VA home. Damage to your roof valleys can be handled with a minor roof repair and this goes a long way to keeping your home dry throughout the seasons.
