CertainTeed Landmark PRO Pewterwood Mansard Roof — Narragansett Ave, Jamestown

Pinnacle makes every roof affordable with monthly financing options to make your home project affordable with low monthly payments, including 0% interest for 18 months.

The former Jamestown Press building at 45 Narragansett Avenue in Jamestown needed a complete mansard roof replacement. A mansard roof is a distinctive architectural feature — steep, nearly vertical sides that function as both wall and roof — and replacing one requires specialized knowledge that goes beyond standard residential roofing. Pinnacle Roofing performed the full tear-off and re-roof with CertainTeed Landmark PRO shingles in Max Def Pewterwood, plus trim repairs to refresh the entire exterior.

Scope of Work

The crew stripped the worn shingles from all mansard faces, inspected the underlying sheathing and framing, and installed the complete CertainTeed Integrity Roof System — ice and water shield, synthetic underlayment, starter strip, Landmark PRO shingles, and matching hip and ridge caps. The steep angle of a mansard demands extra attention to starter course alignment, wind resistance at the transition points, and flashing where the mansard meets the flat or low-slope upper roof. Pinnacle also completed trim repairs along the eaves and rake edges to ensure the entire exterior was refreshed alongside the new roof.

What We Installed (And Why)

CertainTeed Landmark PRO is a heavy-weight architectural shingle with a Class A fire rating, 130 MPH wind warranty, and algae-resistant granules. The Max Def Pewterwood color provides a natural, weathered wood appearance — multiple granule tones layered to create the look of aged cedar without the maintenance. On a mansard roof, the shingle color is especially visible because the steep faces function as exterior walls, making color selection as much an aesthetic decision as a performance one.

As a CertainTeed ShingleMaster Premier, Pinnacle qualifies to offer the SureStart PLUS extended warranty — 50 years of non-prorated coverage including the first 15 years at full replacement cost. That warranty level is only available through credentialed contractors and only when every component in the system comes from CertainTeed.

Good To Know

Mansard roofs present unique challenges that standard residential roofers don’t encounter often. The steep faces (often 70 degrees or steeper) require careful starter course alignment to prevent shingle slippage, and the transition where the mansard meets the upper roof is a critical flashing zone where leaks often originate. Wind behavior around mansard geometry is also different — the nearly vertical faces catch wind directly, creating uplift forces that are more severe than on a standard slope. That’s why wind-rated shingles and proper nailing patterns are essential on mansard applications. Not every roofing contractor has the experience to handle these details correctly.

Why This Approach Works

A mansard roof is as much about the building’s appearance as its weather protection. The Pewterwood color was chosen because it evokes the natural, weathered wood look that fits Jamestown’s coastal village character — without the maintenance burden of actual wood shingles. The CertainTeed Integrity Roof System ensures every component is matched and warrantied together, and the trim repairs complete the exterior refresh so the building looks unified from street level.
