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.
