Seamless Gutters and Leaf Guards on a Coventry Landmark PRO Colonial Slate Roof

A roof is only as good as the water management around it. On this Coventry home, Pinnacle completed the picture — pairing a CertainTeed Landmark PRO roof in Colonial Slate with a full seamless gutter system and leaf-guard protection, so every inch of the roof drains cleanly and the water is carried away from the house instead of down its walls. Pinnacle roofs go on fast — often as a one-day roof replacement — and flexible financing keeps a project like this within reach, with plans as low as 0% interest for 18 months.

With the Landmark PRO roof in place, the focus turned to drainage: continuous seamless gutters formed on-site, matching downspouts, and leaf guards sized for Coventry’s heavy tree cover. This project is in Coventry, Rhode Island, finished in CertainTeed Landmark PRO — Colonial Slate.

Scope of Work

We installed CertainTeed Landmark PRO on this project. Gutters are the last line of a roof system, and we install them as part of it rather than as an afterthought. On this home the crew formed continuous seamless aluminum gutters on-site from a single coil of stock, cut and shaped to each roofline so there are no mid-run joints anywhere along the runs. Hanger spacing was matched to the local snow and rain load so the troughs stay rigid under a heavy New England downpour or an ice-laden winter, and every run was set to a deliberate pitch that moves water steadily toward the downspouts instead of letting it stand. Downspouts were routed to discharge well away from the foundation, and leaf guards were fitted across the full system so Coventry’s tree canopy cannot pack the troughs with debris. Just as important, the gutters were integrated with the roof’s drip edge and gutter apron, so water leaving the last course of shingles is handed directly into the trough with no gap for wind-driven rain to slip behind the fascia.

What We Installed (And Why)

Seamless gutters solve the single biggest weakness of ordinary sectional gutters: the joints. Sectional systems are assembled from short pieces snapped together, and every one of those seams is a spot that eventually loosens, leaks, and stains the fascia below. A seamless gutter is rolled on-site from one continuous length of aluminum, so the only joints are at the corners and outlets — dramatically fewer places to fail over the life of the system. We install a K-style profile, which both looks like traditional crown molding from the ground and holds significantly more water than a rounded half-round gutter of the same width, so it keeps up with the volume a full roof sheds in a hard rain. The leaf guards then keep the whole system self-clearing, which matters enormously on a wooded Coventry lot where oak and maple debris would otherwise clog an open gutter within a season. Overhead, the Landmark PRO roof anchors it all: 130 mph wind resistance, a Class A fire rating, and CertainTeed’s Max Def color process, which layers darker shadow bands beneath the surface granules to give Colonial Slate the multi-tonal, slate-like depth that a flat single-color shingle can’t match.

Good To Know: Why do clogged gutters cause so much more damage than most homeowners expect?

When gutters clog, water does not simply spill over the front lip and disappear — it backs up under the roof edge and pours down behind the gutter, soaking the fascia board and the roof sheathing right at the eave. That is the exact area a new roof is built to protect, and it rots quietly from behind where no one sees it. In winter the same standing water freezes into ice dams that force melt-water back up under the shingles. Overflowing gutters also dump concentrated water at the foundation, which is how basements start to leak. Sealed, guarded gutters keep the water in the system and moving, protecting the roof edge, the walls, and the foundation all at once.

Why This Approach Works

Coordinating the drip edge, gutter apron, and new gutters as one project — by the same crew that laid the roof — is what makes the eave watertight. When gutters are added later by a separate company, that critical roof-to-gutter handoff is a guess; done together, it is engineered, with the shingle, the metal, and the trough all lapping in the right order so water can only go one way: out.

Coventry, Rhode Island

Coventry is Rhode Island’s largest town by area, and much of it is wooded — beautiful, shaded lots of oak, maple, and pine that drop a steady load of leaves and needles onto every roof each fall. That tree cover is exactly why gutter protection matters so much here: an open gutter on a Coventry lot can pack solid in a single season, while a seamless, guarded system keeps working with almost no maintenance. Pairing it with a durable Landmark PRO roof gives a Coventry home a water-management system built for its setting. Explore our work across Coventry roofing services.
