Project Overview
Landmark Pro shingles
on a Vermont log home.
This large log home in Underhill got a full tear-off and shingle replacement using CertainTeed Landmark Pro architectural shingles, along with skylight replacement as part of the scope.
The multi-gable roofline and log construction called for careful flashing work around every valley and penetration, with full ice & water shield coverage throughout to protect the timber structure below.
- Full shingle tear-off and disposal
- Skylight replacement
- CertainTeed Landmark Pro architectural shingles
- Ice & water shield at eaves, valleys, and penetrations
- Synthetic underlayment throughout
- New ridge cap and ridge vents

How It's Done
The complete shingle system,
layer by layer.
A proper shingle replacement in Vermont isn't just swapping old shingles for new ones — it's installing a fully engineered roofing system designed to handle decades of freeze-thaw cycles, heavy snow loads, and ice dam pressure. Here's how we built this Underhill roof from the deck up.
Tear-Off and Deck Assessment
Every full replacement starts with stripping the existing roofing system down to bare sheathing. We inspected every square foot of the Underhill roof deck for rot, delamination, soft spots, and failed fasteners before any new material went on. Damaged or saturated sheathing sections were replaced before the layered system was installed.
Ice & Water Shield
This self-adhering membrane bonds directly to the deck and seals around fastener penetrations, creating a continuous waterproof barrier that holds even when ice dams force standing water beneath the shingles. We installed it at all eaves, valleys, and penetrations — Vermont's freeze-thaw cycles generate serious ice dam pressure, and this layer is what stops it from becoming a leak.
Synthetic Underlayment
Synthetic underlayment was installed across the full roof deck as a secondary moisture barrier — lighter and more tear-resistant than traditional felt, and stable across temperature extremes without wrinkling or going brittle.
CertainTeed Landmark Pro Shingles
CertainTeed Landmark Pro was selected for this Underhill home for its reinforced nailing zone and dimensional profile — strong wind resistance, resistance to premature granule loss, and a clean, substantial finished appearance that holds up in Vermont's harsh UV and freeze-thaw environment.
Ridge Cap, Ventilation & Flashing
New ridge vent was installed along the full ridge line to complete attic ventilation, reducing moisture buildup and helping prevent ice dams at the eaves. All flashing — step, counter, and drip edge — was replaced rather than reused, since corroded or improperly lapped flashing is one of the most common sources of roof leaks.
