Oakmont’s housing stock isn’t like the suburbs that came later. The borough’s streets hold some of the most architecturally distinctive roofs in Allegheny County - steep pitches, multiple valleys, dormers that catch snow and river fog alike. We’ve been working these homes since 1984, long enough to see what lasts and what fails when the wrong material gets installed on a roof that was originally designed for slate. Our Specialty Roofing team doesn’t guess at what’s under your shingles. We inspect, photograph, and tell you exactly what we find before we quote a dollar.
Why Ridgeline Roofing Co. Is Oakmont’s Preferred Specialty Roofing Company
We’ve been serving Oakmont and the surrounding river towns for over 42 years. Pete Navarro started this company in 1984 with the idea that a roofing job should outlast the contractor who sold it - and that means showing up after the work is done, not disappearing to the next storm zone.
Our reputation here is built on repeat customers and neighbors telling neighbors. Homeowners in the 15139 ZIP code call us back because the 90-Day Done Right Promise means something: if it’s not right, we make it right. No forms to mail, no voicemail trees, no arguing about whether the leak was “in scope.” We return, we fix it, we stand behind it.
Response time matters in a river-bottom town where a small leak can turn into a ceiling collapse during one of Oakmont’s hard spring rains. Our phones are staffed live 24 hours a day. Technicians arrive in uniform, background-checked, with photo documentation from your actual roof - not a sales pitch in your driveway based on satellite imagery.
Our Specialty Roofing Services in Oakmont
Solar Ready Roofing
Oakmont’s mature tree canopy and north-facing slopes can make solar tricky, but a proper solar-ready roof starts with decking that can handle the load and flashing that won’t leak where panels penetrate. We install Owens Corning and CertainTeed solar-ready systems with reinforced attachment zones, so when you’re ready for panels, your roofer (or solar installer) isn’t cutting into a 15-year-old shingle field. On a 1920s colonial revival on Allegheny Avenue, we found that a previous contractor had installed GAF architectural shingles directly over original slate skip sheathing. The fasteners had popped, and moisture had rotted the decking; we fully rebuilt the deck with solid plywood before installing a CertainTeed Landmark solar-ready system. That roof will outlast the panels mounted on it.

Green Roof
Green roofs aren’t common in Oakmont, but they’re possible - and surprisingly well-suited to the borough’s flat-roofed commercial buildings and certain low-slope additions on older homes. The river-valley humidity that causes so much trouble with asphalt shingles actually supports sedum and native groundcover once the drainage and root-barrier layers are engineered correctly. We’ve installed modular green roof systems on properties near the Allegheny where stormwater management is a priority. The key is structural load assessment: these systems weigh 15-25 pounds per square foot saturated, and Oakmont’s legacy framing sometimes needs reinforcement. We don’t greenwash a sale. If your structure can’t handle it, we’ll tell you straight.

Modified Bitumen
For flat or low-slope sections on Oakmont’s older homes - often rear additions, porches, or converted carriage houses - modified bitumen is our go-to when TPO or EPDM isn’t the right fit. The torch-applied or self-adhering systems we install from IKO and CertainTeed handle the freeze-thaw punishment better than old-school built-up roofing, and they repair cleanly when ice dams or ponding cause damage. Oakmont’s river-bottom position traps cold air and moisture, making ice dam formation at eaves and in valleys especially severe on the north-facing slopes common here. Modified bitumen’s multi-ply construction and granulated cap sheet resist the thermal cycling that splits lesser materials.

TPO Roofing
White TPO membranes reflect summer heat and hold up well on commercial buildings and larger residential flat roofs in Oakmont. The heat-welded seams create a monolithic surface that doesn’t rely on adhesive tapes that can fail in our humid summers. We install TPO from GAF and CertainTeed with proper insulation packages - critical in a climate where winter cold penetrates and summer sun bakes. For properties near the river where cooling costs spike in July and August, the reflectivity pays back over time.

EPDM Roofing
Black EPDM rubber roofing remains a cost-effective choice for detached garages, sheds, and certain low-slope residential applications around Oakmont. The material flexes without cracking through our 40+ annual freeze-thaw cycles, and repairs are straightforward when punctures occur. We favor ballasted or fully-adhered installations over mechanically fastened in high-wind exposure zones near the Allegheny.

Built-Up Roofing
Some of Oakmont’s oldest commercial buildings and institutional structures still carry built-up roofs - layers of tar and felt that have been patched for decades. We repair these where it makes sense and replace with modern systems when the substrate is saturated. The 1930s-built structures along Allegheny River Boulevard often fall into this category. A full built-up replacement runs higher than a mod-bit conversion, but for historically designated properties or owners committed to period materials, we’ll quote it honestly.

Trusted Brands We Service in Oakmont
We’re authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - seven manufacturer lines, no substitutions without your written approval. For Oakmont customers, this means we stock common accessory pieces locally: ridge vents sized for steep-pitch colonial revivals, valley flashing that handles our heavy snow loads, underlayment rated for the sustained moisture that river fog drives into roof assemblies. We don’t order from a catalog and hope it arrives Tuesday. Our trucks carry what Oakmont’s housing stock typically needs, which shortens most jobs to a single visit once materials are staged.
Common Specialty Roofing Problems We See in Oakmont Homes
- Moss and algae colonization on north-facing slopes. Oakmont’s river-valley microclimate traps morning fog on roofs far longer than inland Allegheny County boroughs. That persistent moisture breeds moss and algae that eat asphalt granules, exposing the fiberglass mat beneath and cutting shingle life by half. We see this most severely on homes above Hulton Road and along the hillside streets where shade from mature oaks never lifts before noon.
- Fastener failure on slate-skip-sheathing conversions. Roofers working the streets closest to the Allegheny - where 1920s homes sit just above the flood line - routinely find that previous contractors installed standard 3-tab or architectural shingles directly over original slate decking boards (spaced skip sheathing, not solid), which voids warranties and causes fastener failure. Any re-roof in lower Oakmont almost always requires a full deck rebuild before new shingles can go down. We photograph the condition and show you before we quote.
- Ice dam formation at eaves and valleys. The combination of humid river air, shaded lots from mature tree canopy, and frequent freeze-thaw creates some of the most aggressive granule loss and premature aging conditions in the immediate Pittsburgh metro. Heat escapes through poorly insulated attic floors, melts snow on the upper roof, and the water refreezes at the cold eave - backing up under shingles and into wall cavities. We address the roofing symptoms and advise on ventilation and insulation improvements that reduce the root cause.
- Undersized asphalt on steep legacy pitches. Many of Oakmont’s early-20th-century homes were originally slated, and roofers here regularly encounter converted-to-asphalt jobs where the original steep pitch and valley geometry were designed for slate drainage, not asphalt’s moisture tolerance. Standard architectural shingles on a 12:12 pitch with complex valley intersections simply don’t shed water fast enough. Specialty materials and enhanced underlayment systems are often the right fix, not another layer of the same.

FAQs - Specialty Roofing in Oakmont
Your shingles are aging faster because Oakmont’s river-bottom position traps fog and moisture against north-facing roofs for hours each morning, accelerating moss growth and granule loss beyond what inland Pittsburgh neighborhoods experience. The mature tree canopy that makes Oakmont beautiful also shades roofs and extends that wet period. If you’re seeing bald patches or gutter sediment after just 8-12 years, it’s likely this microclimate, not defective shingles. Call (844) 563-1816 and we’ll inspect, photograph the damage, and recommend whether cleaning and treatment will extend life or if it’s time for a moss-resistant specialty system.
No, not if the slate is laid on skip sheathing, which is what we find on nearly every pre-1940 Oakmont home near the river. Spaced boards don’t provide solid fastening for modern shingles, and every major manufacturer voids warranties on skip-sheathing installations. We remove the existing layers, install solid plywood decking, and then apply your new roof system - done right, with full warranty protection. The additional cost of deck rebuild is typically $3,000-$6,500 for an average Oakmont home, and we include it in every quote where inspection indicates it’s needed. Call for a free assessment.
Repair if the substrate is dry and less than 30% of the field is compromised; replace if you have saturation, alligatoring across more than half the surface, or recurring leaks at seams and penetrations. Built-up roofs on Oakmont’s riverfront commercial and mixed-use buildings often lasted 40+ years because the multiple tar layers were forgiving, but once water reaches the insulation, patch jobs become money thrown at a sinking structure. We’ll inspect with moisture mapping and give you an honest repair-versus-replace recommendation. Our written estimate for either path is free - call (844) 563-1816.
No, not on a steep slope as your primary roof system - green roofs require near-flat surfaces (typically under 30 degrees) for drainage and media retention. However, if your colonial revival has a flat porch roof, dormer, or rear addition below 6:12 pitch, a modular green roof may be feasible after structural assessment. Oakmont’s humidity actually supports sedum well once established. We evaluate load capacity, drainage paths, and waterproofing integration before quoting. Call to discuss your specific roof geometry.
A solar-ready roof won’t directly prevent ice dams, but the comprehensive deck rebuild and enhanced ventilation that solar-ready installation requires often resolves the heat-loss and airflow problems that cause them. In Oakmont, ice dams form because warm attic air melts roof snow, which refreezes at cold eaves - and many legacy homes have blocked soffit vents, insufficient insulation, or bathroom fans dumping moisture into rafter bays. When we install a solar-ready system, we address decking, ventilation, and often recommend insulation upgrades as part of the scope. The result is a roof that’s ready for panels and less prone to winter damage. Call (844) 563-1816 for an inspection that covers both concerns.
