Composite Shake Roofing in Southern Maine

Composite (also called synthetic) shake is an engineered polymer tile — typically a blend of virgin resin, recycled polymer, UV stabilizers, fire-retardant additives, and color pigments that runs all the way through the tile rather than sitting on the surface. The premium lines are molded from actual hand-split cedar shakes or quarried slates, so the surface texture, the chamfered edges, and the irregular profile are real — not a printed pattern.

The lines we install most often: DaVinci Roofscapes (multi-width and single-width shake, Bellaforté slate), Brava (cedar shake, old-world slate, barrel tile), and F-Wave Revia (a true-shake-profile synthetic with a strong warranty and a more accessible price point). All Class A fire, all Class 4 impact, all 50-year-or-better warranties.

1. Full tear-off and deck inspection. Composite tiles need a sound, flat deck — soft spots come out and get replaced.
2. Ice & water shield + synthetic underlayment. Same Maine assembly as asphalt and metal: ice & water at eaves, valleys, sidewalls, and penetrations; synthetic over the field.
3. Manufacturer-specific starter and battens. Each composite line has its own starter strip and exposure spec — we follow it exactly, because that's what unlocks the warranty.
4. Tile placement and nailing pattern. Composite shake is installed with a specific nailing pattern (typically four nails per tile, in marked locations) using ring-shank stainless or hot-dipped galvanized nails — never staples. Tile exposure is set per the manufacturer's spec.
5. Stagger and width variation. For shake profiles, we vary tile widths across each course so no two courses repeat — this is what makes a composite shake roof read as natural cedar from the street.
6. Hip, ridge, valley, flashing. Manufacturer hip and ridge tiles (not asphalt caps), open or closed valleys per design, sidewall and chimney flashing in copper or coated aluminum.
7. Cleanup and magnet sweep. Same as every job.

Polymer doesn't absorb water — so freeze-thaw cycles that destroy real cedar in 10–15 years on the coast have no effect on composite. Color is molded through the tile, so chips and edge wear don't show. Class A fire ratings exceed what cedar can achieve. Class 4 impact ratings often qualify for insurance discounts. And because the tile is dimensionally stable, you don't get the curling, cupping, and granule loss that ages an asphalt roof from the street.

Coastal capes, shingle-style summer homes, historic colonials, and any home where the look of cedar shake or slate is part of the architecture but the maintenance and lifespan of real cedar isn't worth it. Composite is also a strong call for homeowners who want a premium roof without committing to the metallic aesthetic of standing seam. Less ideal for budgets where premium architectural asphalt would hit the mark, or for very simple ranch homes where the profile detail is wasted.

Manufacturer material warranties run 50 years (DaVinci, Brava) or limited-lifetime (some F-Wave product lines), with strong transferability to subsequent owners — a real factor at resale. Class A fire and Class 4 impact ratings often unlock insurance premium reductions. Our workmanship warranty covers the install. Realistic service life: 50+ years on the coast with effectively zero maintenance.
