Ultimate Roofing

Just in case you were wondering, flashing is the thin metal (usually aluminum or galvanized steel) installed at roof transitions and penetrations — around chimneys, skylights, pipes, and where a roof meets a wall. Its job is to seal these vulnerable areas against water intrusion. Most roof leaks don't originate from failed shingles; they start at failed or improperly installed flashing. Step flashing, counter flashing, and valley flashing are the main types, each suited to a specific location and purpose. Flashing can get damaged from ice or storms and it is important to have a thorough roof inspection done each year to ensure your roof and flashing are in great shape!
