Fast, Reliable Specialty Roofing Across Forest Hills
Specialty roofing in Forest Hills, PA typically costs $8,500-$18,000 for a full system installation, with most jobs completed in two to four days depending on whether your home has hidden slate layers beneath old asphalt. We answer our phones live at (844) 563-1816, every hour of every day, and our crews are usually on Forest Hills roofs within 24 hours of your call.
We’ve been working the borough’s hills since 1984, and we know what waits under those shingles. Forest Hills’s streetcar-era homes, built mostly between the 1920s and 1950s, carry a secret that newer suburbs don’t: original slate roofs buried under decades of asphalt overlays, masonry chimneys with flashing worn raw by Allegheny County’s freeze-thaw cycle, and north-facing slopes that stay damp through March. Our Specialty Roofing team doesn’t guess at what’s underneath. We inspect, photograph, and tell you exactly what your roof is holding before we quote a number that won’t change.
From Ardmore Boulevard up to the slopes near Braddock Hills, we travel Forest Hills’s narrow, tree-lined streets with trucks sized for tight borough lots. Pete Navarro started this company on the principle that a roof should be done once and done right, and that means showing up prepared for what Forest Hills actually builds, not what the textbook says.
Why Ridgeline Roofing Co. Is Forest Hills’s Preferred Specialty Roofing Company
Forest Hills homeowners call us back because we answer the phone. A live person, 24/7, including the night a February ice dam starts dripping through your bedroom ceiling. No voicemail tree, no “we’ll call you back between 8 and 5.” We’ve served this region for over 42 years, and our technicians are background-checked, uniformed, and trained to document every inspection with photos from your actual roof, not a sales pitch in your driveway.
Our 90-Day Done Right Promise means what it says. If something isn’t right, we make it right. No paperwork to file, no argument about whether the problem existed before we touched it. That promise has kept us in business since 1984, long after storm-chasing crews left Pittsburgh for the next hail event.
We hire local crews and train apprentices into journeymen. Our trucks carry stock for GAF, CertainTeed, and Atlas systems, so most Forest Hills repairs don’t wait on parts. And our upfront pricing means the estimate we leave on your kitchen table matches the invoice we hand you at completion. A square deal: the price we quote is the price you pay.
Our Specialty Roofing Services in Forest Hills
Modified Bitumen Roofing
Modified bitumen is our go-to recommendation for Forest Hills homes with low-slope additions, dormers, or enclosed porches that original builders roofed with whatever was cheap in 1947. These areas sit on older homes that were never designed for modern membrane systems, and Pittsburgh’s wet winters punish them hard. A properly torched or self-adhered mod-bit system gives you the flexibility to handle the thermal movement of a 90-year-old structure without the brittleness of aging asphalt. Typical installation on a Forest Hills porch or dormer runs $4,200-$7,800, including tear-off of whatever failing material we find underneath.

Built-Up Roofing (BUR)
Built-up roofing still earns its place on Forest Hills’s flat-roofed garages, rear additions, and occasional commercial buildings along Ardmore Boulevard. The multiple-ply construction handles foot traffic and resists the ponding that happens when borough gutters clog with oak and maple debris. We install BUR with coal-tar pitch or asphalt, depending on the structure and your preference, and we always inspect the underlying deck for the rot that decades of Pittsburgh precipitation can hide. A standard Forest Hills garage BUR replacement typically falls between $3,800 and $6,500.

TPO Roofing
TPO’s white reflective surface makes sense for Forest Hills homeowners battling summer heat in upper-floor bedrooms, especially on south-facing slopes that catch full sun above the borough’s tree canopy. We install TPO from GAF and CertainTeed with full adhesion or mechanically attached systems, depending on your roof’s structural capacity. On older Forest Hills homes, we often encounter decking that can’t handle the weight of a traditional system, and TPO’s lighter profile solves that without sacrificing durability. Single-story flat or low-slope TPO installations in the borough generally range from $5,500 to $10,000.

Solar Ready Roofing
Forest Hills’s mature tree canopy blocks panels on some lots, but the south-facing slopes above Braddock Hills and along the higher elevations near the borough’s eastern edge get enough sun to make solar viable. Our solar-ready installs use decking and flashing systems engineered for the additional penetrations and load, so you’re not re-roofing twice when panels go up. We coordinate with your solar contractor on attachment points, waterproofing, and warranty compatibility. A solar-ready specialty roof in Forest Hills typically adds $1,200-$2,800 to a standard replacement, depending on system size and penetration count.

EPDM Roofing
EPDM rubber membrane remains a cost-effective choice for Forest Hills’s detached garages and small flat-roofed additions where the homeowner wants 20-year performance without premium pricing. The material handles Pittsburgh’s temperature swings well, and repairs are straightforward when a falling branch punctures the surface. We install fully adhered and ballasted systems, and we always replace edge metal and coping caps as part of the job, since those are the failure points we see most often on older borough structures. EPDM garage roofs in Forest Hills generally run $3,200-$5,800.

Green Roofing
Green roofs are uncommon in Forest Hills, but we’ve installed them on two borough homes where the homeowner wanted stormwater management and the structural engineer confirmed the load capacity. The 1920s framing in most Forest Hills homes cannot support a full intensive green roof without reinforcement, so we typically design extensive systems with shallow growing media for drought-tolerant sedum. These projects start around $15,000 and require a structural assessment as the first step.

Trusted Brands We Service in Forest Hills
We are authorized installers for seven manufacturer lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Forest Hills homeowners, that authorization matters because it means your warranty is factory-backed, not dependent on a contractor who might not answer next year. We stock GAF and Atlas membranes and shingles at our local warehouse, so most Forest Hills repairs don’t wait on delivery. When we quote a system, we specify the exact product line, not “or equivalent.” You get what we promise, installed to the manufacturer’s specification, with paperwork that protects your investment.
Common Specialty Roofing Problems We See in Forest Hills Homes
- Hidden deck rot under layered asphalt-over-slate roofs. Forest Hills’s 1920s-1950s homes frequently have original slate buried under two or three asphalt overlays, adding 2-3 tons of dead weight and trapping moisture against decking that was never designed for it. We find soft or compromised plywood on roughly one in three tear-offs in the borough, and we won’t install a new system until the structure is sound.
- Failed masonry-chimney flashing from freeze-thaw damage. Allegheny County crosses 32 degrees more than 90 days per year, and that cycle works step flashing loose from brick and mortar that was already aging when Eisenhower was president. Water follows the path of least resistance, often appearing as stains on bedroom ceilings far from the chimney itself.
- Ice dams overwhelming old valley flashing on north- and east-facing slopes. Forest Hills’s tree canopy and eastern-hill elevation keep these slopes shaded and damp through winter. Insufficient attic insulation, common in pre-1950 construction, melts snow from below; the water refreezes at the eave, backs up under shingles, and finds your ceiling.
- Abnormal structural loads from surprise slate discoveries. We recently worked on a Schoenfield Street colonial where the homeowner noticed a sag in the ridge line. Our tear-off revealed three layers of asphalt over original slate, with deck rot near the chimney. We removed all layers, repaired the deck with 5/8″ plywood, and installed a CertainTeed asphalt shingle system with new step flashing. The job took three days instead of the usual two because of the extra debris and structural assessment.

FAQs - Specialty Roofing in Forest Hills
Yes, all layers must come off. The original slate adds 2-3 tons of dead weight your framing was never engineered to carry indefinitely, and it traps moisture that rots decking from below. We won’t install a new system over hidden slate because we can’t warranty work on a compromised structure. Removing everything lets us inspect, repair, and build a roof that will last. Call (844) 563-1816 for a free inspection and exact quote.
Look for rust stains on the brick, gaps where step flashing meets mortar, or granules collecting at the chimney base. On Forest Hills’s 90-year-old homes, freeze-thaw cycles work flashing loose long before water reaches your ceiling. We inspect chimney flashings as part of every roof evaluation and document condition with photos. If you see any of these signs, call before the next hard rain.
It’s likely Gloeocapsa magma algae, which thrives on damp, shaded surfaces and is extremely common on Forest Hills’s north- and east-facing slopes that rarely dry between November and April. The streaks themselves don’t damage shingles immediately, but they hold moisture that accelerates granule loss and invites moss colonization. We treat affected areas during roof replacement and can recommend zinc or copper strip installation to prevent recurrence. For a diagnosis specific to your roof, call for a free inspection.
Sometimes, but only if the underlying structure is sound and the damage is isolated. On Forest Hills’s aging housing stock, we frequently find that what looks like a small leak points to widespread deck rot or systemic flashing failure. We offer honest assessments: if a patch will buy you five years, we’ll say so. If the roof is telling you it’s done, we’ll show you the photos and explain why. Our $89 Seasonal Tune-Up includes a full inspection to help you decide. Call (844) 563-1816 to book.
Steep pitches add 10-25% to labor costs because they require additional safety equipment, slower work pacing, and more material waste. Forest Hills’s 1920s-1950s homes are almost uniformly steep-gabled, so we price for this reality upfront rather than surprising you later. The structural integrity of these older roofs, not just the pitch, is what determines final cost. We assess both during your free estimate.
