Discover 5 roof leak prone areas

Homeowners find roof leaks a major nuisance.  This is because not only are they challenging to diagnose, but the location of the leak depends on weather changes. Many roof coverings use the gravity principle to operate, thus make it easy for you to notice the source of a leak. However, if you have horizontal roof boards, it may be tricky for you to discern the area that is leaking.  Since a leak might be eight feet sideways from the spot where you see wet ceiling, it is important to hire Roof Repairs at PMC Roof Contracting experts, to diagnose the leak. Some of the common leak locations may include:

The shingles field

In case your roof is old, the leak might be in the roof field. This implies the area around the shakes, slate and shingles.  You can easily walk on your roof if it is asphalt.  However, in case your roof is made of materials such as clay tile, concrete tiles, or slate, it is not advisable to walk on it as it may crack. With regular shingles, check the tops of the upright knockouts. Check for cracks, missing colored granules, or a missing nail. Basically, check for any possible cause of the leaking roof.


Roof planes intersect on a line known as a valley. Some homeowners use rolled roofing, or metal flashings on the valley. If your roof shingles are not well trimmed, valleys can pose big problems. Trimming shingles for valleys gives you chisel points on the shingles ends. If you do not make a second cut, the point looks like an arrow point, and water may get into your house though the chisel.


Water mainly finds its way into the house through the chimney. Chimneys have four distinct types of flashing. All these flashing must be well installed. Also, the counter flashing, which leads to your brick mortar joint, should be well. In case the flashing develops any crack, you should hire roof repairs at PMC Roof contracting experts to prevent flow of a large amount of water behind the flashing.

Head wall flashings

If your roof rests on a vertical wall, you should have a metal flashing to direct the streaming of water down the wall. The flashing might be at the front of a wall made of brick or behind wood siding. To prevent any leaks, ensure the flashing over the shingles are about three inches wide.

Plumbing vent flashing

Many newer vent flashing integrates a rubber seal that has an aluminum flashing. This rubber may fail within a shorter period of ten to fifteen years. Check the plumbing pipes to see if there is any cracked rubber.

Before you blame your roof for any leak, it might be important to hire roof repairs at PMC Roof contracting experts to diagnose the leak. At times, you might think that your roof is leaking, while it is fine. For instance, you may experience attic condensation.  This occurs when high humidity leads to rain and condensation to fall on the attic. It may also make the roof’s underside appear wet. This may make you think you have a leaking roof.
