New shingles make a roof look renewed. Some of the most important junctions may still be the old ones.
Ask for a junction-by-junction scope
Have the roofer identify wall intersections, chimneys, roof openings, and penetrations. Ask which flashings are expected to remain, which are being replaced, and what might only be decided after opening the area.
IKO's flashing guidance calls for assessing existing flashings and signs of leakage during reroofing. Condition and the proposed installation detail matter more than a blanket claim that old flashing is always fine or always wrong.
Include the adjacent wall work
Replacing a roof-to-wall detail can involve cladding or masonry work. Ask who handles that restoration and whether it is included. A quote for new flashing is incomplete if it leaves access to the junction or the wall repair undecided.
Record the final decisions
- Locations where existing flashing remains and why.
- New materials and junction details where work changes.
- Associated wall, chimney, or siding repairs.
- Photographs before the new covering conceals the work.
Ask how these choices relate to the roof-system instructions and the written warranty. Do not assume a new shingle warranty covers every old junction in the house.
Our preference is an explained decision for each important intersection. The roof should work as an assembly, even when some sound components remain. A uniformly new appearance is pleasant; a coherent water path is the actual objective.
