Expert Verdict — Reviewed by the SuperArbor Pro Desk

For curb-mounted skylights, lap the flashing into the roofing underlayment and shingles so water shed off the curb rides over, not under, the roof plane. Build the curb with proper slope or follow the skylight manufacturer's curb detail, and seal the skylight-to-curb joint as instructed. Use the kit variant that matches the exact curb size designation.

Use fall protection when installing flashing at roof level, and follow the manufacturer's flashing sequence to keep the assembly watertight.
