Exterior Work in Mt. Lebanon
What we actually find on Mt. Lebanon houses, who issues your permit, and how long it takes us to get there.
Top Dog Exteriors is an exterior contractor based at 4607 Library Rd in Bethel Park, PA, working in Mt. Lebanon. Mt. Lebanon is a home rule township in Allegheny County, and building permits for exterior work here are issued by Mt. Lebanon Inspections, Permits & Zoning. We install roofing, siding, decks, windows, doors, gutters and concrete, and every roofing and siding installation carries a written, transferable 5-year workmanship warranty on our labour.
What Mt. Lebanon houses actually need
Slate and tile roofs are genuinely common here, not a rarity. Tile and slate were the most expensive roofing money could buy in western Pennsylvania in the early twentieth century, and a properly maintained slate roof lasts anywhere from 75 to 250 years. Patching one with asphalt or corrugated metal is the visual mistake you cannot undo.
- The National Register historic district listed in 2014 covers roughly 4,400 properties across 38 subdivisions. Contributing buildings sit inside the boundary and were built before 1945.
- The street-tree canopy in the oldest neighbourhoods is 90 to 120 years old. Mt. Lebanon maintains around 10,000 street trees and replaces removed ones as policy — beautiful, and hard on gutters.
- Pre-1945 houses were not built for modern gutter sizing or modern flashing details. Most of what we correct here was correct for 1928.
The housing stock
A streetcar suburb. The first subdivision was platted in 1901 and the Liberty Tubes opened in 1924; the population went from 2,258 in 1920 to 13,403 in 1930. Historic-district buildings date from 1874 to 1945.
Tudor Revival and Colonial Revival dominate, alongside Georgian, Renaissance Revival, Arts and Crafts, Spanish Mission and French Medieval, with Craftsman bungalows and Foursquares in large numbers.
Permits in Mt. Lebanon
Permits for work here are issued by Mt. Lebanon Inspections, Permits & Zoning. Mt. Lebanon runs its own inspection department rather than contracting it out.
We pull the permit and meet the inspector. We deliberately do not publish permit fees — municipalities revise them, sometimes annually — so we confirm the current figure with the office while we are writing your estimate rather than quoting you something out of date.
Getting there
About 3 miles, roughly 8 minutes from our shop on 4607 Library Rd in Bethel Park.

The crew did an outstanding job — extremely clean, highly professional, and impressively efficient. Their communication throughout the project was excellent, keeping me informed at every step. They had repaired my roof last year, and when a severe storm came through, I knew exactly who to call. The owner was on site to check the workmanship, which gave me even more confidence in the quality of the project. The roof looks fantastic, and the entire process was smooth and well-executed. I couldn’t be happier with the results.

Answered my request for an estimate to repair storm damage to my home with inspection, and estimate in two days. When I confirmed and signed work started next day. Work was completed within two days and I added other items as the quality and attention to detail was first rate. I recommend.
