Aggressive, shallow, wide-ranging surface roots that heave driveways, sidewalks and patio slabs, and elms in general are on every plumber's list of species that find old clay and tile sewer laterals. It also suckers off those roots, so an untreated stump regenerates and seedlings colonize gravel, fence lines and mulch beds every spring.
50 to 70 ft tall with a broad, open, irregular crown, and it gets there fast — a 25-year-old Siberian elm is already a full-size removal. It is short-lived for its size, commonly under 60 years in the Midwest, so many are structurally spent while still looking like a healthy shade tree, and that combination pushes removals into the high-cost crane-or-rigging bracket.
