CertainTeed Roofing in Detroit, CA | Ridgeline Roofing Co.
We provide independent CertainTeed roofing service across Detroit’s core ZIPs - 48231, 48232, 48201, and 48202 - with OEM-compatible parts stocked for same-day starts on most repairs. The one thing that makes our CertainTeed work here different is that we expect the unexpected beneath the shingles: original 1×6 tongue-and-groove plank decking so rotted from decades of deferred maintenance and moisture migration off vacant neighbors that full deck replacement is routine, not rare. Call (844) 563-1816 - a live person answers, including nights and weekends.
Why Detroit Residents Choose Us for CertainTeed Service
Pete Navarro, our owner, grew up in Eagle Rock and learned this trade at Los Angeles Trade-Technical College before spending twenty years on roofs across the San Fernando Valley and Eastside. He started Ridgeline Roofing Co. in 1984 because he was tired of watching homeowners get talked into materials they didn’t need and flashing that got shortcutted. That same plainspoken approach is what we bring to every CertainTeed sales & service call in Detroit.
We’re not a CertainTeed authorized contractor, and we don’t pretend to be. What we are is independent technicians who know these product lines inside out - Landmark, Presidential, Independence, Symphony Cedar - and who understand how they behave in Detroit’s pre-1950 housing stock. Our crews are background-checked, uniformed, and trained to document every inspection with photos from your actual roof, not the driveway below. When we quote a job, the number on the estimate is the number on the invoice. And every job carries our written 90-Day Done Right Promise - if it’s not right, we come back and make it right, no paperwork, no arguing.
Phones are staffed by a live person 24 hours a day. Not a callback window. Not a voicemail tree. A real voice, because a leaking roof doesn’t wait for business hours.
Common CertainTeed Roofing Problems We Solve in Detroit
- Algae discoloration on lighter Landmark shingles - Detroit’s dense east-side blocks, where homes sit shoulder-to-shoulder and adjacent structures block afternoon sun, create permanent shade bands across roofs. We see this most on north-facing slopes in 48205 and 48211. The algae doesn’t hurt the shingle structurally, but it makes a fifteen-year roof look thirty. We stock darker Landmark Pro colors for replacement sections and can treat affected areas without a full re-roof when the granule layer is still sound.
- Premature granule loss on Independence shingles - These are thick, premium shingles designed for impact resistance, but Detroit’s severe freeze-thaw cycling is harder on them than the design spec anticipated. Granules shed most aggressively during March and April thaws, when daytime sun hits frozen shingles and the expansion-contraction cycle loosens the bond. We inspect Independence roofs annually after the second thaw and replace individual tabs before the asphalt substrate is exposed.
- Edge curling on Landmark Pro shingles - The pre-war bungalows and two-flats throughout 48201 and 48202 were built before modern attic ventilation standards. Retrofitted soffit vents often don’t pull enough air through original 1×6 plank decking, especially when insulation has been blown in without baffles. Heat and moisture build at the eaves, and the shingle edges curl upward within eight to twelve years. We fix the ventilation first, then replace the affected courses.
- Fishmouthing in Presidential shingles - These heavy laminated shingles telegraph every imperfection in the substrate. On Detroit’s historic homes with original wood plank decking - which is most of them - the planks cup and crown over a century of seasonal movement. Presidential shingles installed directly over this surface develop characteristic half-moon gaps at the tab edges. We won’t install Presidential over plank decking without first laying structural OSB or plywood over the planks.
- Accelerated deck rot from adjacent vacant structures - This one is Detroit-specific and we see it constantly. In densely built east-side blocks, a still-occupied home shares a party wall or sits within feet of a vacant house with a collapsed roof. Moisture migrates through shared walls and across narrow gaps, rotting the occupied home’s sheathing from the inside out. The shingles look fine from the street. We find the damage during inspection and rebuild the deck before any new CertainTeed product goes down.
CertainTeed Service in Detroit: What Local Conditions Mean for Your Roof
In Detroit’s east side ZIPs like 48205 and 48211, roof work must account for moisture intrusion from neighboring vacant homes. We often discover that deck rot on an occupied home originates from an adjacent collapsed roof - a pattern almost unknown elsewhere. You can stand in the attic of a well-kept bungalow on Gratiot Avenue and watch the sheathing darken from the inside out, even though the CertainTeed shingles above are only twelve years old and the homeowner has maintained them properly. The failure isn’t in the product or the installation. It’s in the context.
This changes how we scope every Detroit service area job. We don’t assume standard sheathing. We don’t quote from the curb. Our technicians inspect the attic interior, the shared wall conditions, and the neighboring structure’s roof status before we recommend shingle replacement, full roof replacement, or flashing repair. A roof doesn’t lie - it just waits until the rain to tell you the truth. In Detroit, sometimes the truth is coming from next door.
For CertainTeed owners specifically, this means warranty claims can get complicated. Manufacturer defect coverage typically excludes damage from “external moisture sources,” and an insurance adjuster may argue that adjacent vacancy is maintenance-related rather than storm-related. We document everything - photos, moisture meter readings, neighboring structure condition - so you have a complete file if you need to pursue coverage.
CertainTeed Models & Products We Service in Detroit
We work with all major CertainTeed residential lines:
- Landmark Series - including Landmark, Landmark Pro, and Landmark Premium; the workhorse line we see most often on Detroit’s bungalows and two-flats
- Presidential Series - heavy laminated shingles popular in historic districts for their slate-like appearance; require rigid substrate preparation on Detroit’s plank decking
- Independence Shingle - impact-rated for severe weather; granule loss monitoring is essential in freeze-thaw climates
- Symphony Cedar - synthetic shake for specialty applications; limited Detroit inventory, but we can source within 48 hours
We use OEM CertainTeed shingles for color matching and warranty continuity, but we’re honest about flashings and underlayments. When CertainTeed-brand accessories don’t improve durability over quality aftermarket alternatives, we say so. Our Detroit warehouse stocks Landmark and Presidential in the most common Detroit colors - Weathered Wood, Colonial Slate, Georgetown Gray - so patch jobs and partial replacements don’t wait on factory shipping.
CertainTeed Service Pricing in Detroit
Detroit’s housing conditions push our pricing higher than suburban estimates you might find online. Here’s what drives cost:

FAQs - CertainTeed Roofing in Detroit
No. We are an independent CertainTeed service provider, not a manufacturer-authorized contractor. Only CertainTeed-certified installers can register and transfer the full SureStart Plus warranty. We provide our own written 90-Day Done Right Promise on workmanship, and we use OEM shingles that maintain the product’s base material warranty. For full SureStart coverage, you’d need to work with a CertainTeed SELECT ShingleMaster. Call (844) 563-1816 and we can explain the difference - estimates are free.
We address the heat loss first. Ice dams form when warm air escapes through pre-war attic floors and melts snow at the ridge; water runs down and refreezes at the cold eave. On CertainTeed roofs, this lifts shingles, rots fascia, and backs water under flashing. We install proper intake and exhaust ventilation, seal attic bypasses, and replace damaged shingles with matching OEM product. In severe cases we recommend ice-and-water shield at the eaves during full replacement. Call (844) 563-1816 for an inspection before the next thaw.
Sometimes, but rarely in Detroit’s core ZIPs. Michigan code allows one overlay, but the condition of the original wood plank decking underneath makes overlay risky here. We often find rot, moisture damage from adjacent vacancies, or previous patchwork that an overlay would conceal. We recommend tear-off in most cases so we can inspect and replace decking as needed. The homeowner in Boston-Edison whose Landmark Pro we installed last spring originally asked about overlay; once we showed her the nailer strip condition in the photos, she understood why tear-off was necessary.
Landmark Pro for most applications. It carries a 50-year product rating, has thicker laminate layers than base Landmark, and the color palette works with Detroit’s brick housing stock. For homes in historic districts with clay tile or slate originally installed, Presidential Series gives the dimensional look without the weight structural concerns. Independence is worth considering if you’re in a heavily treed area with branch-drop risk. We don’t recommend products based on margin - we recommend based on what your roof structure, your neighborhood, and your budget can support.
No. We operate independently and do not partner with authorized contractors for warranty handoffs. If your roof was installed by a CertainTeed credentialed contractor and you’re within the SureStart period, you should contact that installer or CertainTeed directly for warranty service. We come in when the original installer is gone, when the warranty has expired, or when you need an honest second opinion on whether the problem is material defect or installation error. Our Free Second Opinion on Any Written Estimate applies here - bring us another contractor’s scope and we’ll review it with you, no charge.
