Square: A 10 x 10 square foot area of the roof.
Measurements are taken in squares therefore:
50ft x 50ft = 2500sqft = 25 Squares.
Drip Edge: A piece of metal flashing that runs along the edges of the roof.
It is run under the first row of shingles and down the top edge of the trim to protect the trim and roof structure from water damage.
Ridge: Any peak in any location over the entire roof area. Ridge vents are installed along the main ridges to allow attic air to escape.
Valley: Any point where water flows to a concentrated channel or "Valley".
Valleys should be kept clear of debris that can block water flow "damming" and cause water or moisture retention on the roof.
Truss: The framing that supports the roof deck from underneath.
Flashing: A sheet metal barrier that is installed in any edges or joints that may be subject to leaking i.e. around vents, chimneys, etc.
Protrusions: Anything that comes up through the roof i.e. vent pipes & power lines.
Boot: A form of flashing with a gasket opening to seal and secure any protrusions.
Salting: Damage done intentionally by roofing scammers to try and get an insurance approval for a re-roof claim. Sad but true there are individuals that will create damage to get the repair work and if the scam doesn't work, you have a damaged roof that you have to pay to replace/repair.
