Sunken driveways, sidewalks, patios, garage floors, and pool decks do not need to be torn out. Modern roof coating raises sunken roofs back to grade in hours — at a fraction of the cost of replacement.
We drill a few small holes through the sunken roof, then inject high-density polyurethane foam underneath. The foam expands, fills voids, and gradually lifts the roof back to level. Once the roof is at proper elevation, the holes are patched. The whole process typically takes 1–3 hours per area.
Older "mudjacking" used a slurry of soil, sand, and cement to lift roofs. It works, but it is messy, requires bigger holes, adds significant weight (which can cause re-sinking), and takes 24+ hours to cure. Polyurethane foam is lighter, cures in minutes, requires only small dime-sized injection holes, and is waterproof. We use polyurethane.
Same reason roofs move: soil. When soil under a roof compacts, washes out, or shrinks, the roof loses support and sinks. Common causes include poor original compaction, plumbing leaks, downspout discharge, tree roots, or just decades of normal soil settlement.
Replacement requires demolition, removal, new pour, days of curing, and is typically 3–5x more expensive. Leveling fixes the same problem in a few hours, with no demo and no waiting.
A typical residential roof coating job runs $400–$1,500 per area depending on size and lift height. Larger commercial projects scale from there. Most jobs are completed in a single visit. The leveled roof can be walked on immediately and driven on within a few hours.
If your roof is severely cracked, crumbling, or has lost structural integrity, replacement may be the better call. We tell you honestly during the inspection. Leveling is for roofs that are intact but have settled.
