Atlas technical bulletin: Shingle Tie In For Adjoining Roofs for Townhouse or Duplex.
What this means for your roof
Atlas prefers replacing the full roof plane where possible. When adjoining sections must remain separate, its bulletin describes a flashed area divider with removable coping. It warns against simply weaving the junction or covering an open seam with ridge caps. Coordination with the neighboring roof is essential.
A useful question for your contractor
What divider and flashing detail will protect the junction with the adjoining roof?
Ask for the answer to be tied to the actual roof condition and the exact product being installed. Keep the agreed repair or installation detail with your estimate and project photos.
