Why Ridgeline Roofing Co. Is Plum’s Preferred Roof Replacement & Installation Company
We’ve been serving Allegheny County homeowners for over 10 years, and Plum has been part of our route since the beginning. Pete Navarro, our owner, still reviews every major replacement estimate personally. We’re not a storm-chasing crew with out-of-state plates - we’re the company that hires local apprentices and trains them into journeymen who know how Plum’s hilly terrain traps ice on north-facing slopes.
Our customers in Plum call us back because we show up when we say we will. Our 90-Day Done Right Promise means if something isn’t right, we make it right - no paperwork, no arguing. Background-checked, uniformed technicians document every inspection with photos from your actual roof, not a scary speech in your driveway. And a live person answers every call, including the middle of the night when that ice dam finally lets water through your ceiling.
Our Roof Replacement & Installation Services in Plum
Full Roof Replacement
Most full replacements we do in Plum involve homes built in the 1960s and 1970s whose original roofing systems are hitting end-of-life all at once. The borough’s primary residential buildout produced a dense concentration of split-level and ranch homes now 50-60 years old, and we’re seeing that wave of simultaneous failures across neighborhoods like Liberty Hills and the areas near Boyce Park. A typical full replacement on a Plum split-level runs $10,500-$16,000 for asphalt shingles, with metal systems starting around $18,000. We handle permits, debris removal, and material staging - critical on acreage properties with long, sloped service drives where a standard dump trailer won’t cut it.
New Construction Roofing
New builds in Plum are less common than replacements, but we do handle them - particularly on the larger acreage lots where homeowners are adding detached workshops or guest structures. We coordinate with framers and general contractors to ensure proper ventilation and ice-and-water shield placement, especially on low-pitch garage sections that will catch runoff from steeper main roofs. The same freeze-thaw cycle that damages aging roofs will test a new one just as hard if it’s not built right from the sheathing up.
Asphalt Shingle Installation
Asphalt shingles remain the workhorse choice for Plum’s housing stock, and we install them with specifics this climate demands. We favor CertainTeed Landmark PRO and GAF Timberline HDZ systems for their performance in heavy snow load and algae resistance - important given Plum’s humid summers and dense tree canopy. On north-facing slopes, which stay frozen solid through multiple melt-refreeze cycles, we extend ice-and-water shield well beyond code minimums. A standard architectural shingle job on a Plum ranch runs $8,500-$14,000. The price holds. What we quote is what you pay.
Metal Roofing
Metal roofing makes particular sense for Plum’s acreage properties with detached workshops. The material sheds snow faster than asphalt, which matters when you’re dealing with cascade designs where one roof section dumps onto another. We install standing seam and metal shingle systems from Tamko and Atlas, properly flashed at every transition. Metal runs $18,000-$28,000 for a typical Plum home, but it carries a longer lifespan and performs better on low-slope sections where asphalt struggles. For workshop buildings that see heavy use, it’s often the smarter long-term investment.
Flat Roofing
Flat and low-slope sections are the hidden vulnerability in Plum’s split-level architecture. The low-pitch roof over your garage or rear addition collects runoff from the steeper main roof above, and it’s almost always where we find soft decking, failed flashing, and interior ceiling stains. We install TPO, modified bitumen, and built-up systems designed for this exact challenge. On Plum properties, we never treat the flat section as an afterthought - it’s frequently the most critical part of the job.

Trusted Brands We Service in Plum
We’re authorized installers for seven manufacturer lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Plum’s climate, we most often specify GAF and CertainTeed asphalt systems with enhanced ice-and-water shield packages, or Tamko and Atlas metal products for workshop and outbuilding applications. We don’t substitute materials without your sign-off. What we specify is what arrives on your roof, and we stage everything properly - especially important on acreage properties where a missed delivery means lost hours on winding roads.
Common Roof Replacement & Installation Problems We See in Plum Homes
- Ice dam damage at low-pitch transitions. The cascade design common on Plum split-levels - steeper main roof draining onto a shallower garage roof - creates predictable failure points. Snowmelt from above refreezes on the colder lower section, backing water under shingles and into decking. We inspect these transitions first on every Plum inspection.
- Algae and moss degradation from shaded, wooded lots. Plum’s heavy tree canopy blocks sunlight and traps humidity, accelerating granule loss on asphalt shingles. North-facing slopes are particularly vulnerable. We specify algae-resistant shingles and recommend proper limb clearance where practical.
- Detached workshop roofs replaced in isolation. Homeowners often address a leaking workshop roof months or years after the main house, missing the chance to coordinate materials, crew scheduling, and hardware upgrades in one efficient project. We bundle these jobs when it makes sense for the homeowner.
- Premature opener and spring failure on oversized workshop doors. Standard residential garage door hardware isn’t built for the 10-foot or 12-foot doors common on Plum acreage workshops. The heavier doors strain under-equipped systems, and we’ve seen springs fail within two years of installation by contractors who didn’t ask the right questions.

FAQs - Roof Replacement & Installation in Plum
Yes. We regularly bundle workshop roof replacement with main-house jobs on Plum’s acreage properties, coordinating materials and crew scheduling so everything’s done in one trip. This saves you money and avoids the headache of managing two separate contractors across Plum’s winding roads. Call (844) 563-1816 to schedule a walkthrough of both structures - estimates are free.
We specify algae-resistant architectural shingles with enhanced ice-and-water shield for Plum’s shaded, north-facing sections. CertainTeed Landmark PRO and GAF Timberline HDZ both perform well in this application. The algae resistance matters because those slopes stay damp longer, and the extended ice-and-water shield protects against the freeze-thaw cycle that defines Allegheny County winters. Pete Navarro reviews every specification personally to match materials to your home’s specific exposure.
Yes, though we always inspect the main roof’s condition and the flashing where the two sections meet. The garage roof fails first because it catches all the runoff, but the transition flashing is often the real culprit. If the main roof has five or more years of life, a targeted garage replacement with upgraded transition detailing can be the right call. We’ll give you an honest assessment - no pressure to do more than necessary.
We stage materials in a dedicated laydown area close to the work zones, never blocking your drive or creating hazards on sloped approaches. On challenging Plum properties, we use smaller delivery vehicles or multiple trips rather than risk a stuck dump trailer on a wet, winding drive. Our crew lead walks every property beforehand to plan the safest, most efficient approach. We’ve learned this the hard way over 10 years - preparation prevents delays.
Yes. Standard residential hardware fails quickly on the 10-foot and 12-foot doors common in Plum’s workshop buildings. We install heavy-duty torsion spring systems and appropriately rated openers as part of our bundled workshop service. On a recent job in the Liberty Hills area, we upgraded a homeowner’s workshop springs while completing their roof replacement - all in one crew trip, one coordinated schedule. Call (844) 563-1816 to discuss your workshop door specifications.
