We’ve been working on Medford roofs since 1984. Pete Navarro started this company with the belief that a roof should be done once and done right, and that a handshake still means something. In Medford, that philosophy matters more than most places. The triple-deckers along High Street, the Colonial Revivals tucked behind Medford Square, the bungalows climbing toward the Fells - these houses weren’t built yesterday, and they deserve a roofer who understands what they’re built on.
Why Ridgeline Roofing Co. Is Medford’s Preferred Roof Replacement & Installation Company
Medford homeowners don’t call us for flashy sales pitches. They call because their neighbor called, or because they remember the last contractor who disappeared. We’ve earned that trust over 42 years by showing up, doing what we said we’d do, and standing behind it.
Our crews live in the communities we serve, not in trucks that follow storm damage from state to state. When you call (844) 563-1816, a live person answers - 24 hours a day, including the middle of a February Nor’easter when ice dams are pouring into your third-floor unit. Our technicians are background-checked, uniformed, and trained to document every inspection with photos from your actual roof, not from the driveway below.
We back every job with our written 90-Day Done Right Promise. No paperwork to file, no runaround, no arguing. If it’s not right, we make it right. That’s the standard Pete Navarro set in 1984, and it’s the standard we hold today.
Our Roof Replacement & Installation Services in Medford
Full Roof Replacement
In Medford’s 02155 ZIP code, the dominant pre-1935 housing stock - triple-deckers and Colonial Revivals - often still has original skip-sheathing designed for slate, which complicates tear-offs and demands careful deck evaluation before any re-roof. We don’t nail new shingles over rotted wood or insufficient fastening surfaces. Our crew inspects every square foot of decking, replaces what’s failed, and installs proper sheathing where skip-boards won’t hold modern fasteners. A full replacement on a typical Medford triple-decker runs $18,000-$28,000; a single-family Colonial Revival generally falls between $14,000 and $22,000.
Flat Roofing
On the triple-deckers clustered around Medford Square and High Street, the flat or near-flat roofs over third-floor enclosed porches were often built without proper crickets or interior drains. When gutters on the main pitched roof dump water onto these flat sections in a Nor’easter, the ponding routinely forces water back under the fascia into the top-floor unit. We install fully adhered TPO and modified bitumen systems with proper drainage - not patches that’ll fail next season. Flat roof replacement on a Medford enclosed porch typically costs $4,500-$9,500 depending on access and drainage complexity.
On a triple-decker near Medford Square, we tore off three layers of old asphalt shingles to find original skip-sheathing over a back-porch flat roof. The ponding from a Nor’easter had forced water under the fascia into the top-floor unit, so we installed a fully adhered TPO membrane with interior drains, resolving a chronic leak that had baffled previous contractors.
Asphalt Shingles
Asphalt shingles remain the practical choice for most Medford pitched roofs, but the wrong shingle on skip-sheathing is a recipe for blow-offs. We specify architectural-grade products with proper nailing patterns and, where decking requires it, full sheathing replacement first. For Medford’s humid microclimate, we favor algae-resistant granules - the streaking here is worse than in drier towns west of the river. A typical asphalt re-roof on a Medford two-family runs $12,500-$19,000; single-family homes generally start around $11,000.
New Construction
Whether it’s an addition off a Spring Street Victorian or a new build on a subdivided lot near the Mystic, we install from the deck up to manufacturer specifications. No shortcuts on ventilation, no missing ice-and-water shield at the valleys. New construction roofing in Medford typically ranges $9,000-$16,000 for asphalt on standard footprints.

Trusted Brands We Service in Medford
We install GAF, CertainTeed, and Owens Corning systems - proper materials, no substitutions. These aren’t just brand names to us; they’re products we’ve watched perform through Medford’s wet winters and humid summers for decades. We stock common accessory items locally, so when a Medford job needs additional ridge vent, drip edge, or ice-and-water barrier, we’re not waiting on a truck from two states away. That matters when a Nor’easter is 48 hours out and your tear-off is already half-done.
Common Roof Replacement & Installation Problems We See in Medford Homes
- Ice dams along eaves and gutters worsen freeze-thaw cycles due to cold-air pooling in the Mystic River valley, damaging flashings and underlayment. We see this annually on river-adjacent streets where the topography traps cold air that suburban Arlington simply doesn’t experience.
- Flat or near-flat roofs on enclosed porches of triple-deckers lack proper crickets or drains, causing ponding that forces water under fascia into living spaces during Nor’easters. This failure mode is so common in Medford that we inspect for it on every multi-family estimate.
- Skip-sheathing from original slate roofs complicates nail placement for asphalt shingles, leading to poor fastener hold and blow-offs if decking isn’t replaced first. We evaluate every deck before specifying materials.
- Algae streaking and moss colonization accelerates on north- and east-facing planes in Medford’s elevated-humidity microclimate, shortening shingle lifespan and creating unsightly - and eventually damaging - surface growth.

FAQs - Roof Replacement & Installation in Medford
In most cases, yes - skip-sheathing spaced for slate won’t hold modern asphalt shingle nails properly, and we’ve seen blow-offs within two years when contractors nail over it. We evaluate every deck during tear-off; if boards are sound and properly spaced, we may install plywood over them, but rotted or insufficient decking gets replaced. Call (844) 563-1816 and we’ll inspect your specific roof - estimates are free.
The elevated humidity and ponding from main-roof gutter overflow demand fully adhered membranes with proper drainage, not torch-down patches or rolled asphalt. TPO or modified bitumen with interior drains and crickets handles Medford’s conditions; inferior systems fail repeatedly. We specify materials rated for ponding water and install drainage that moves water off the roof, not into your top-floor ceiling. Call (844) 563-1816 for a flat-roof assessment.
Medford’s valley topography traps cold air along low-lying streets, extending the freeze-thaw window and keeping roof edges below freezing while upper roof sections warm and melt snow. Arlington’s higher elevation drains cold air more readily. That temperature differential drives meltwater to the eaves, where it refreezes into dams that back up under shingles. We install proper ice-and-water shield and evaluate ventilation to mitigate this - but the geography doesn’t change. Call (844) 563-1816 before the next freeze.
If the substrate is dry and the drainage geometry is correct, targeted repairs may last. But on Medford triple-deckers with chronic ponding and no interior drains, we’ve found repairs typically buy 12-18 months before the same leak returns. Full replacement with proper membrane and drainage solves the root problem. We’ll give you an honest assessment either way - call (844) 563-1816 for a free inspection.
GAF Timberline HDZ and CertainTeed Landmark PRO both offer algae-resistant granules and full nailing zones that perform well on re-sheathed or properly prepared decks. For skip-sheathing that must be covered rather than replaced, we prefer Owens Corning Duration for its SureNail strip and wind resistance. We never substitute unauthorized materials - what’s specified is what arrives on your roof. Call (844) 563-1816 to discuss options for your house.
We’re here when you need us. A live person answers every call to (844) 563-1816 - 24 hours a day, 7 days a week. Whether you’ve got active leaks, suspect your skip-sheathing is failing, or just want an honest assessment of how many seasons your current roof has left, we’ll come out, climb up, and tell you what we see. No pressure, no surprises, just a square deal from a company that’s been standing behind local roofs since 1984.
