Lean-to and addition bays in Erie County, PA
22 townships covered
Open bays and enclosed additions hung off an existing building — with the snow-drift engineering that junction demands here.
This comes up often enough around here that most post-frame builders have a settled way of handling it.
How this normally starts
- Firewood, trailers, or implements that need a roof but not walls
- A barn that filled up the year after it was built
- A building that works except for the one bay it's missing
- Livestock that needs shade and a windbreak more than a full barn
What the work involves
A lean-to hangs a single-slope roof off an existing post-frame wall, or stands on its own posts alongside. The critical part in this climate is making sure the existing trusses and the new connection can take the drifted snow that piles where two roofs meet.
What your project actually costs can only be settled by a registered builder who sees the site. Footprint, sidewall height, doors, finish level and ground conditions all move it.

Townships we cover for this
Only the areas where this work actually applies.
Lakeshore and grape belt
The narrow plain between the lake and the escarpment — vineyards, orchards, and the heaviest lake-effect snow in the county.
Inland farm country
South and east of the escarpment: dairy, crops, horses, and hill ground where elevation adds to an already serious snow load.
