GAF Slateline Antique Slate Gray — Wilbert Way, North Kingstown

Like most Pinnacle roofing projects, the work was completed in a single day — minimizing disruption for the homeowner.

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.

This new pool house at 76 Wilbert Way in North Kingstown needed a roof that matched the existing home and outbuildings. The homeowner selected GAF Slateline shingles in Antique Slate Gray — a designer-grade shingle that replicates the look of natural slate at a fraction of the cost. Pinnacle Roofing installed the Slateline shingles to match the rest of the property, giving the new pool house the same premium appearance from day one.

Scope of Work

Pinnacle installed the full GAF roof system on the new pool house — underlayment, starter strip, GAF Slateline shingles in Antique Slate Gray, and matching hip and ridge caps. The crew coordinated with the builder to ensure the new roof matched the existing home and other structures on the property — same color, same shingle line, same installation standard. On a new construction pool house, the goal is seamless visual integration with the existing property.

What We Installed (And Why)

GAF Slateline is a designer shingle that’s engineered to replicate the dimensional look of natural slate. The oversized tabs, tapered cut-outs, and bold shadow lines create a profile that mimics hand-cut slate — an effect that standard three-tab or even architectural shingles can’t achieve. The Antique Slate Gray color uses a specially formulated granule palette that blends gray, charcoal, and subtle warm tones to match the weathered appearance of aged natural slate.

The key advantage of Slateline over actual slate is practical: real slate weighs 800 to 1,500 pounds per square (100 sq ft) and requires specialized structural support, installation by a trained slate roofer, and individual piece replacement when repairs are needed. Slateline delivers the aesthetic at roughly one-fifth the weight and a fraction of the cost, with standard installation techniques and straightforward maintenance. For a pool house that needs to match an existing slate-look roof, it’s the right choice.

Good To Know

Designer shingles like GAF Slateline occupy a tier above standard architectural shingles but below genuine natural materials. They’re engineered to replicate the look of slate, shake, or tile using asphalt shingle manufacturing technology — which means they install like standard shingles, weigh roughly the same, and don’t require structural reinforcement. The trade-off is that the look, while convincing from the ground, doesn’t have the exact texture and aging character of real stone or wood. For most residential applications — and especially for matching an existing roof across multiple structures — designer shingles provide the visual impact of premium materials at a practical price point and maintenance level.

Why This Approach Works

When a new outbuilding needs to match an existing home, consistency matters — same shingle product, same color, same installation quality. The GAF Slateline in Antique Slate Gray gives the pool house the same premium appearance as the main home from the day it’s finished. The shingles weather at the same rate, so the color match improves over time rather than diverging. Using one roofing contractor for all structures on the property ensures consistent installation standards across every roof.

Why Pinnacle

Pinnacle Roofing is skilled at installing specialty shingles from CertainTeed, GAF, and Owens Corning — including designer lines like GAF Slateline that require specific installation techniques for the oversized profile. Not every crew handles designer shingles regularly, and the installation details — starter course alignment, exposure spacing, and hip and ridge integration — are different from standard architectural shingles. Whether it’s a new construction match project like this one or a full residential roof replacement, the quality standard stays the same. With over 100 five-star Google reviews and an A+ BBB rating, our track record speaks for itself.
