Flow Down The Roof

The metal roof forms a valley where one roof meets another.

Flow down the roof. Penetrations can include plumbing and roof vents chimneys dormers or anything else that projects through the roof. Look for potential entry points like roof vents valleys loose nails and mark the area with chalk so you can examine the exterior of your roof after it quits raining. The slope of a roof or pitch is determined by how many inches the roof rises over 1 foot or 12 inches. This is worst when there is a door or a window below and water can seep behind the trim.

If you have attic access the easiest way to track down a leak is to go up there with a flashlight and look for the evidence. Look for damp spots on the underside of your roof. Hot air exhaust vents located at the peak of the roof allow hot air to escape. Numerous people have tried ideas but none have worked.

Intake vents located at the lowest part of the roof under the eaves allow cool air to enter the attic. Drip edge is available at hardware stores and it is made. To put it in perspective the angle of this slope would be around 30 degrees. Kick out flashing is critical where a roof edge meets a sidewall.

If the slope of the roof is reduced a point will be reached at which pressure on the windward slope becomes zero. Place a piece of standard metal drip edge onto a table or between a pair of sawhorses. Bring a 20 foot sewer auger onto the roof. This means that the rise of the slope goes up or down 8 inches for every 12 inches.

Insert the head into the vent opening and feed it down until you encounter resistance. This valley shoots rain in a flume during our frequently heavy downpours. Without it roof runoff flows down the wall and possibly into the wall. Follow the water uphill till the wood is no longer wet.

They can be several feet above the leak or to the right or left of it. An example for a steep sloped roof is 8 12. Also look for a thin stream of water flowing down one of the rafters. Turn it upside down so the lip edge faces upwards.
