We’ve been climbing roofs in Mount Lebanon since 1984. Pete Navarro started this company with the belief that a roofer should be someone you call once and trust forever, not a stranger who blows through town after a hailstorm. The homes here deserve that steadiness. Tudor Revival cottages on Lenox Road, stately Colonials along Washington Road, the brick-and-stone Craftsmans tucked into Sunset Hills - these weren’t thrown up fast. Neither is our work.
Why Ridgeline Roofing Co. Is Mount Lebanon’s Preferred Specialty Roofing Company
Mount Lebanon homeowners know their roofs. Many have lived under the same slate for thirty or forty years. They notice when a patch doesn’t match, when a valley starts weeping after January’s freeze-thaw cycle, when the copper flashing has lifted again. We don’t talk down to that experience. We add to it.
Our reputation here was built one repair at a time. Homeowners in 15228 call us back because we show up in uniform, photograph every inch of the roof from a ladder, and explain what we’re seeing without pushing a sale. The 90-Day Done Right Promise means if something isn’t right, we make it right - no forms to mail, no arguments, no runaround. That’s been our standard since 1984.
A live person answers our phones 24 hours a day, including the middle of a February ice storm when water starts threading through a cracked Vermont slate at 2 a.m. We don’t do callback windows. We don’t leave you stranded. Our technicians are background-checked and trained in-house, apprentice to journeyman, the same path Pete Navarro walked.
We know the local conditions that punish Mount Lebanon roofs: Pittsburgh’s South Hills absorbs brutal freeze-thaw cycling, temperatures swinging above and below freezing dozens of times each winter. That pattern cracks brittle aged slate, lifts copper valley flashing, and drives ice dams along the deep eave overhangs that make Tudor-style homes so distinctive. Annual snowfall averaging 30-40 inches loads steep rooflines that were designed for it but are now supported by century-old framing. This isn’t theoretical for us. We’ve repaired it, documented it, and stood behind our work through it.
Our Specialty Roofing Services in Mount Lebanon
Slate Repair and Matching
This is the work that defines our Specialty Roofing team in Mount Lebanon. The borough’s core neighborhoods - Sunset Hills, Virginia Manor, the streets fanning off Washington Road - hold an unusually high concentration of original slate and clay-tile roofs from the 1920s through 1950s. Homeowners here overwhelmingly prioritize slate repair and matching rather than replacement with asphalt, and that preference shapes everything we do.
On Lenox Road, we found a 1930s Tudor Revival with a zinc-strip patch over a cracked Vermont slate; the homeowner had tried three contractors who mismatched the color. We sourced a near-identical Gettysburg green slate from a Pennsylvania quarry, repaired the copper valley flashing, and restored the roof’s historic pattern without a full replacement. That kind of quarry-matching skill separates a specialist from a generalist. We carry sample boards of regional slates - Vermont purples, Pennsylvania grays, New York reds - so we can match in place, not guess from a catalog photo.
Typical slate repair in Mount Lebanon runs $2,800-$7,500 for partial restoration, while full slate replacement on a medium-sized Tudor Revival ranges $18,000-$24,000.
Modified Bitumen Roofing
Modified bitumen serves Mount Lebanon’s low-slope additions, sun porches, and garage roofs - the secondary structures that many 1940s and 1950s homes acquired as families grew. These areas collect snow melt and ice dam runoff from steep main roofs, so the membrane has to handle standing water and thermal movement. We install torch-applied and self-adhering systems from GAF and CertainTeed, layered for the freeze-thaw abuse this climate delivers. A typical modified bitumen installation on a Mount Lebanon garage or porch roof runs $8,500-$14,000.
Built-Up Roofing (BUR)
For flat sections on older commercial buildings along Washington Road or the borough’s institutional structures, built-up roofing still outperforms many modern alternatives when installed by crews who understand the craft. We lay multiple plies of asphalt-impregnated felt, hot-mopped and surfaced with gravel or a reflective cap sheet. It’s labor-intensive, but on a structure that will stand another century, the longevity justifies the investment. Built-up roofing in Mount Lebanon typically ranges $12,000-$20,000 depending on square footage and access.
Solar Ready Roofing
Mount Lebanon’s preservation-minded homeowners increasingly ask about solar, but they’re rightly cautious about drilling mounting hardware into 90-year-old slate. Our solar-ready assessments evaluate whether the existing roof can support panels, whether the framing and sheathing need reinforcement first, and whether integrated solar shingles from CertainTeed might preserve the historic profile better than rack-mounted panels. We won’t bolt panels onto a roof that needs restoration first. That’s not a sale; that’s a judgment call, and we make it honestly. Solar-ready preparation and structural reinforcement in Mount Lebanon runs $3,500-$8,000 before panel installation.
TPO and EPDM Roofing
For contemporary homes in Mount Lebanon’s newer sections and for commercial properties, we install white TPO and black EPDM single-ply membranes. These aren’t the right choice for a 1925 Tudor, but they serve their purpose on flat or low-slope applications where cost and energy efficiency matter. TPO installation in Mount Lebanon averages $9,500-$15,000; EPDM runs $8,500-$13,500.

Trusted Brands We Service in Mount Lebanon
We are authorized installers for GAF, CertainTeed, Owens Corning, Atlas, Tamko, and Boral - seven manufacturer lines, no substitutions without your written approval. For Mount Lebanon’s slate work, we source directly from regional quarries and specialty distributors whose inventory isn’t available through big-box channels. That local supply relationship matters when you’re trying to match a 1930s Gettysburg green or a 1940s Vermont purple. We stock common copper flashing profiles and lead-coated valley metal for the repair work that keeps Mount Lebanon’s historic roofs alive. Most specialty material orders arrive within three to five business days, and our crew schedules the repair as soon as it hits the truck.
Common Specialty Roofing Problems We See in Mount Lebanon Homes
- Freeze-thaw cracking of original Vermont slate. Pittsburgh’s South Hills winters deliver 30-40 inches of snow and dozens of freeze-thaw cycles annually. Water seeps into hairline fractures, expands when it freezes, and widens the crack over seasons. By the time a homeowner spots a leak, the slate may have been compromised for years. We inspect with photos from the roof surface, not the driveway.
- Lifted copper valley flashings from ice dams. The deep eave overhangs on Mount Lebanon’s Tudor-style homes create dramatic shadows and architectural character - but they also trap meltwater that refreezes at the eave edge. That ice works under copper valley flashings, lifting them from the substrate and opening channels for water to enter at lower roof slopes. We’ve repaired this pattern on homes throughout Sunset Hills and Virginia Manor.
- Mismatched slate patches from prior DIY or non-specialist repairs. On streets like Lenox Road, we routinely find three or four different slate colors and thicknesses layered onto a single roof plane. Each patch tells a story - a homeowner in the 1970s who grabbed what was available, a contractor in the 1990s who didn’t know Pennsylvania slate from imported synthetic. That patchwork history is actually useful: a knowledgeable contractor can read it to date the roof, identify the original quarry region, and source correct replacement slate. It’s a conversation that resonates with Mount Lebanon’s preservation-minded homeowners, and it’s a skill that simply doesn’t apply in neighboring suburbs with newer housing stock.
- Structural load concerns on century-old framing. Those steep rooflines were engineered for slate, but 90 to 100 years of moisture, insect damage, and deferred maintenance can weaken rafters and sheathing. Before we recommend any specialty roofing work, we assess whether the structure can still carry its intended load - and we tell you plainly if it can’t.

FAQs - Specialty Roofing in Mount Lebanon
Your roof likely carries patches from multiple repairs over 50 to 70 years, each using whatever slate was available locally at the time. In Mount Lebanon, we’ve found up to five distinct slate types on a single roof - some from Vermont quarries, some from Pennsylvania, some modern imports that weather differently. Our crew reads that patchwork to identify the original slate source and match it correctly. Call (844) 563-1816 and we’ll assess your roof’s history - estimates are free.
Repair is usually the better investment if the underlying structure is sound and less than 30% of slates are damaged or mismatched. Full replacement becomes necessary when widespread delamination, rotted sheathing, or failed structural support makes patching uneconomical. In Mount Lebanon, where original slate contributes significantly to home value and historic character, we recommend repair-first evaluation. We’ll photograph the roof and show you exactly what we found - no guesswork, no pressure. Call for a free assessment.
Lifted copper valley flashings from ice dam formation along deep eave overhangs. Pittsburgh’s freeze-thaw cycles drive water under flashing edges, and the steep lower slopes of Tudor designs concentrate that runoff. We repair the flashing, improve ice dam prevention, and match surrounding slate so the fix disappears visually. Same-day emergency service is available - call (844) 563-1816.
Sometimes, but rarely without structural preparation first. Slate roofs from the 1930s were not framed for panel loads, and drilling mounting feet through historic slate destroys material that cannot be matched. We assess framing, sheathing, and slate condition before recommending either reinforced racking or integrated solar shingles that preserve the roofline. Solar-ready preparation runs $3,500-$8,000. We’ll tell you honestly if your roof is a candidate - call for a free evaluation.
Original Vermont slate on Mount Lebanon homes typically shows finer grain, more consistent thickness, and specific weathering patterns - a soft, even fading rather than the blotchy discoloration of lower-grade imports. Our crew can often identify the quarry region by color, texture, and how the slate has aged on your specific roof exposure. That identification lets us source matching material rather than approximating. Call (844) 563-1816 to schedule a documented inspection.
Done right - and if it’s not, we make it right. That’s been our standard since 1984. If your Mount Lebanon home has a slate roof showing its age, mismatched patches, or winter leaks along the valleys, call Ridgeline Roofing Co. at (844) 563-1816. A live person will answer, day or night, and we’ll get you scheduled for a free, photo-documented estimate. We plan to be repairing roofs in this borough for decades.
