Your Mt. Lebanon Roofing, Deck & Exterior Contractor
Top Dog Exteriors serves Mt. Lebanon from our shop on Library Road in Bethel Park — close enough that estimates come back fast and warranty calls do not sit in a queue. Roofing, decks, siding, windows, doors, gutters, concrete, additions and site work, all under one contract.
What we see on Mt. Lebanon homes
Historic-district homes and slate-era rooflines need a contractor who respects the architecture.
Western Pennsylvania is hard on the outside of a house. Freeze-thaw cycling works at every seam and every slab. Heavy wet snow loads valleys. Summer storms come through with enough wind to lift a poorly nailed shingle course, and the mature oak and maple canopy across Allegheny County fills gutters faster than almost anywhere else in the state.
That is the environment we build for. It is why we detail flashing and kick-outs before we hang siding, why we size gutters to actual drainage area instead of defaulting to 5-inch everywhere, why we specify air-entrained concrete mixes, and why we dig footings below frost line rather than to whatever depth is convenient.
Every trade, one contractor
Most exterior companies in the Mt. Lebanon area sell one trade and hand the rest off. We cover ten — roofing, decks, siding, windows, doors, gutters, concrete, additions, excavation and painting. Many of our crews specialise in one specific type of that work and have done it for years; some carry more than one speciality. Whichever of them is on your house, when your roof meets your siding and your siding meets your gutters, there is exactly one company responsible for the seams.

I’ve worked with Top Dog Exteriors on multiple roofing projects as a general contractor, and they have consistently delivered excellent results. Their team is professional, responsive, and takes pride in the quality of their work. They show…

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.
Mt. Lebanon Homeowner Questions
Do you serve Mt. Lebanon, PA?
Yes. Mt. Lebanon in Allegheny County is inside our core service area. We are based at 4607 Library Rd in Bethel Park, so Mt. Lebanon is a short drive — which means faster estimates, faster scheduling and faster warranty response than a contractor coming from across the county.
How fast can you get to a Mt. Lebanon property?
Estimates in Mt. Lebanon are typically scheduled within a few days and returned within 24 hours of the visit. Emergency roofing and storm damage calls are triaged the same day. Project scheduling depends on the trade and the season — roofing and gutters move fastest, decks and additions book further out.
Do you pull permits in Mt. Lebanon?
Yes. We pull the municipal permit and meet the inspector on any project that requires one — decks, additions, and structural work all typically do. Every municipality in Allegheny County handles setbacks, footing inspections and framing sign-off a little differently, and knowing that in advance is most of the job.
What does a roof replacement cost in Mt. Lebanon?
Most full architectural shingle replacements in the Mt. Lebanon area run between $9,000 and $22,000 depending on square footage, pitch, layers of tear-off and decking condition. Standing seam metal typically runs two to three times an asphalt roof. Our instant roof quote tool gives you a real range for your specific Mt. Lebanon address in about 60 seconds.
Are you licensed and insured in Pennsylvania?
Yes. We are registered with the Pennsylvania Attorney General as contractor PA193451 and carry general liability and workers' compensation insurance on every job. Certificates are furnished on request.
