We’ve worked on roofs in Tenafly since the mid-1980s, back when many of the borough’s grand Tudors and Colonials were already fifty years old. We know the difference between a slate roof that needs three new courses and one that needs a full restoration. We know which valleys on Knollwood Lane ice up every February, and why the north-facing slopes off Englewood Avenue stay damp enough to grow moss in July. This is not generic suburban roofing. Tenafly’s housing stock demands specific knowledge, and we’ve built our reputation here one honest repair at a time.

Our Roof Repair Services in Tenafly
Valley Repair
Tenafly’s pre-war Tudors and Colonial Revivals were built with complex multi-valley layouts that channel massive volumes of meltwater during freeze-thaw cycles. These valleys are the hardest-working joints on your roof, and they fail first when ice dams back up behind under-insulated attic spaces. We replace valley metal with custom-formed copper or lead-coated copper on historic homes, or with matching color-profile steel on newer construction. On a recent job near Hardenburgh Avenue, we stripped a failed woven valley on a 1938 Tudor and installed a proper open valley with soldered copper flashings - the kind of detail that lasts forty years, not four.
Flashing Repair
Chimney flashings, dormer cheeks, and wall abutments on Tenafly’s older homes were often done in copper or lead that has now thinned after ninety years of acid rain and freeze-thaw. We form replacement flashings on-site to match original profiles, and we understand the permit expectations Bergen County inspectors have for historically appropriate materials. On a steep, north-facing slate roof on Knollwood Lane, we found legacy copper flashings at a chimney corroded and replaced them with new formed copper, then spot-replaced tin-clad slates damaged by a falling limb. We also installed a zinc strip to inhibit future moss growth, matching the adjacent original 1920s slate.
Leak Repair
Leaks in Tenafly rarely come from obvious holes. They travel. Water enters at a failed vent boot, runs along a rafter, and drips from a light fixture three rooms away. Our inspections trace the actual path. We see the same patterns repeatedly: ice dam infiltration behind complex valleys on hillside lots, wind-driven rain through lifted cedar shakes on east-facing slopes, and slow seepage at dormer sidewalls where caulk has hardened. We fix the source, not just the symptom.
Flat Roof Patch
Tenafly has fewer true flat roofs than neighboring towns, but the ones that exist - typically on additions, porches, or carriage houses - are often original built-up roofing from the 1950s or 1960s. We patch with matching modified bitumen or TPO, depending on the substrate condition, and we always check that the drainage scuppers are clear. Standing water on a flat roof in Tenafly’s tree canopy means leaves, and leaves mean accelerated membrane failure.

Trusted Brands We Service in Tenafly
We are authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - and we stock repair materials for all seven lines at our Bergen County warehouse. For Tenafly homeowners with premium original materials, this matters. When we repair a cedar shake roof, we source matching hand-split shakes from Tamko or Atlas inventory. When we patch an asphalt shingle roof on a home that originally had CertainTeed Grand Manor or GAF Camelot, we do not substitute a builder-grade tab. We match the existing course. That is how you maintain a roof’s integrity and appearance without a full replacement.
Common Roof Repair Problems We See in Tenafly Homes
- Moss-accelerated spalling on north-facing slate. Tenafly’s mature oak and maple canopy keeps north-facing slate and cedar roof damp for hours after rain, fostering moss and lichen colonies that accelerate shingle spalling and lift far more aggressively than in sunnier neighboring towns like Cresskill. We clean with low-pressure methods and install zinc or copper strips at the ridge to inhibit regrowth without damaging historic material.
- Ice dam damage from under-insulated attics. Many pre-war homes in Tenafly still have original attic insulation conditions that contribute to ice dam formation. Warm air escapes, snow melts at the ridge, water runs to the cold eave, and refreezes. The resulting dam backs water under shingles and into valleys. We repair the damage and recommend targeted ventilation and insulation improvements that do not require gutting the attic.
- Corrosion at copper or lead flashings. Prolonged dampness from tree canopy and minimal winter sun on north- and northeast-facing planes accelerates the thinning of century-old flashings at chimneys, dormers, and wall abutments. We replace with formed copper or lead-coated copper, soldered properly, to match original life expectancy.
- Wind lift on cedar shakes with advanced lichen colonization. Lichen roots penetrate cedar shake surfaces, loosening the bond and creating entry points for wind-driven rain. On 1950s cedar roofs in the East Hill area, we see this regularly. We replace individual affected shakes and treat surrounding areas to slow colony spread.

FAQs - Roof Repair in Tenafly
You likely need both. Moss that has taken hold for multiple seasons usually lifts slate edges and accelerates spalling, so cleaning alone leaves damaged courses that will leak within a year. We clean with low-pressure, non-abrasive methods, then spot-replace spalled or lifted slates with matching reclaimed or new slate, and install a zinc strip at the ridge to slow regrowth. Call (866) 756-1978 for a free inspection - we will tell you exactly how many slates need replacement before any work starts.
On a pre-war Tudor with complex dormers, we almost always replace the full valley rather than patch it. Patches in woven valleys fail at the next freeze-thaw cycle because the underlying problem is usually inadequate valley metal and ice dam backup from attic heat loss. We strip to the decking, install proper ice and water shield, and lay in new open valley metal - copper on historic homes, color-matched steel where appropriate. The repair takes one day and carries our 90-Day Done Right Promise.
We address ice dams in two stages: repair the damage they caused, then reduce the conditions that create them. For repair, we replace compromised shingles, flashings, and decking at eaves and valleys. For prevention, we inspect attic insulation and ventilation, then recommend targeted improvements - often adding soffit vents and sealing bypasses without major demolition. On Tenafly’s hillside lots with minimal winter sun exposure, this combination is more effective than heating cables alone. Call (866) 756-1978 to schedule a pre-winter inspection.
Yes, if the underlying structure is sound and the lichen has not penetrated more than 30-40% of the roof area. We remove individual affected shakes, treat adjacent areas with a zinc-based solution that inhibits regrowth, and install matching hand-split cedar from our Tamko or Atlas inventory. We also trim back overhanging branches where possible to increase airflow and sun exposure. If lichen has compromised the majority of the roof, we will tell you honestly that repair is no longer economical.
We match the existing product line whenever possible: CertainTeed Grand Manor or Belmont for slate-look profiles, GAF Camelot or Slateline for dimensional replacements, Owens Corning Berkshire for heavy-weight applications. We do not substitute downgrades. As authorized installers for all seven major brands, we can source exact matches or the closest current equivalent, and we document the specification in your written estimate. If your original roof used IKO or Atlas products, we maintain stock for those lines as well.
