Roof Flashing: Its Importance

Installing a new roof, or repairing an existing one, may require this very important part of the roofing material puzzle piece. A properly installed roof is not just shingles, metal panels and a whole bunch of nails. Seems that the Earth’s gravity pulls the elements downward and possibly into crevasse and channels that are the right size for moisture. While the shingles or metal panels are the most visible and the most discussed when discussing a new roof, your contractor understands there is more to proper installation than nailing down the visible flat coverings.

Roof flashing can be described as a thin metal material that roofers install to direct water away from certain areas of your roof. Examples can be exterior walls, chimneys, roof valleys, vent caps) Flashing is a crucial roofing material that every roof needs to have. When discussing the new installation of your roof with your sales contractor, bring up the subject of what to expect when the installers are on your roof and what they will do to protect the adjacent angles.

Also of importance, if you having your roof repaired, and not fully reinstalled, discuss with the roof repairman if the need for repair is associated with the previously installed flashing. Ask the contractor to check other areas of flashing concerns. What do the vents look like; how about the flashing around the chimney if you have one; can the contractor do a double check for the flashing behind gutter (most times referred to as drip edge).

Roofing installers are not always the ones installing drip edges, the team that installed the gutters should see to this but the roofing contractor may see a concern just from his/her experience.

Chimney Flashing

Your chimney is in almost perpendicular angle from the surface of your roof. Even if someone neatly snugged up your shingles or metal panels to the chimney surface, moisture (rain, melting ice, snow) will find its way in to the wooden decking. Flashing is laid down prior to the shingle/metal application to cover the angle. Sealant is applied to keep the moisture from getting in behind the flashing, then the shingles are applied over the “horizontal’ plane. The moisture from the elements are controlled and will not penetrate the perpendicular angle.

Like the other roofing materials, flashing and the sealant can age from the climate. Inspection of a roof should include the health of this aspect also.

Vent Flashing

Roof vents can be attached to kitchen range vents, water heater exhaust, bathroom exhaust fans, attic ventilation. Each one must be tended to individually and precisely.

Valley Flashing

Two adjacent plains of a roof may meet at an angle forming a valley at the junction. Since your roofing materials (shingles or metal panels) cannot be made to curve or bend the meet edge should be protected by a formed angle strip of metal that again is nailed to the decking, sealed as previously, then uniformly covered with shingle or metal panels.

To finish, when you have your initial sit down with your roofing contractor or roof repairman, remember to discuss this crucial element of roof protection. Flashing is not just a quick subject to mention then revert back to the visible shingles. Take time before the contractor visit to step out in your yard and take note of what all your home’s roof has “springing” from it. Notice the number and placement of vents; if you have a chimney, at what angle does the decking follow; if there are angles where different plains meet, will the existing valley flashing need to be replaced.

Flashing, shingles, metal panels, underlayment, wooden decking, ventilation. There are a number of elements in protecting your home. Chris Quarrier and his CQ Roofing team is extensively seasoned in all these aspects in connecting the puzzle pieces.
