Vermont Roofing FAQ

These are the two most common residential roofing choices in Vermont, and both are solid options — the right one depends on your budget, how long you plan to stay in the home, and your roof's pitch and geometry.

Our take: If you're planning to stay in the home for 20+ years and have experienced ice dam problems, the math on standing seam often works out — lower lifetime cost, fewer headaches, and better snow performance. For most other situations, a quality architectural shingle installed correctly is an excellent roof.

Ice dams form when heat escaping through your roof melts snow at the ridge, water runs down to the cold eaves, and refreezes. The result is a wall of ice that traps water and forces it under your shingles.

Immediate fixes

After heavy snow, use a roof rake from the ground to pull snow off the lower 3–4 feet of your roof. This eliminates the fuel source before a dam can form. Never use a metal tool on shingles or climb on a snow-covered roof.

For an existing dam, lay calcium chloride in a nylon mesh tube or old pantyhose across the dam — it melts a drainage channel without damaging shingles. Avoid rock salt, which corrodes metal flashing and kills plants below.

The real fix

Ice dams are almost always an attic insulation and ventilation problem. If your attic is warm, your roof deck is warm, and that's what melts the snow. The solution is to make the entire roof deck cold:

• Add insulation at the attic floor to stop heat escaping from your living space
• Ensure soffit vents and ridge vents are clear and providing continuous airflow
• Air-seal any gaps around light fixtures, pipes, or hatches in the ceiling below

When we do a roof replacement on a home with a history of ice dams, we always run ice-and-water shield further up the roof than code minimum — typically 6 feet from the eave — as added insurance. But that's a band-aid. Fixing the attic is the cure.

The Owens Corning Duration shingle line comes with four warranty tiers. The tier you receive depends on how many OC components are installed and your contractor's certification level. All tiers are lifetime warranties on the shingle material — what differs is how long labor is covered and whether the TRU PROtection non-prorated period is 10 years or 50 years.

*After thermal sealing. Wind coverage applies to blow-offs and wind damage within the stated speed. See owenscorning.com/warranty for full terms.

What Forthright provides on top

Regardless of which OC manufacturer tier applies, Forthright provides a 10-year workmanship warranty on all shingle roof installations. This covers installation errors — the most common real-world failure point — for a full decade. For standing seam metal roofs we provide a 3-year workmanship warranty.

Key things to know

• "Lifetime" is owner-tied. On resale, coverage converts to 40 years. A one-time warranty transfer is available for a fee.
• OC components matter. To qualify for System Protection and above, a minimum of 3 Owens Corning component categories must be installed (underlayment, ventilation, ice & water, hip & ridge, or starter shingles).
• Register within 30 days. All tiers above Standard require registration with OC after installation. We handle this at project closeout so nothing falls through the cracks.
• Algae coverage at 25 years requires OC-approved hip & ridge shingles. Without them it drops to 10 years.

Englert offers one of the widest color selections in the standing seam metal industry, with over 40 standard colors in their Kynar 500 PVDF coating line. Kynar coatings carry a 40-year finish warranty against fading, chalking, and peeling — critical in Vermont's UV and freeze-thaw environment.

Popular Vermont choices

Englert also offers custom color matching for projects requiring a specific match to existing trim or siding. Lead times on custom colors run 4–6 weeks. For standard colors, lead time is typically 1–2 weeks.

Important: Digital swatches don't capture the metallic sheen accurately. We strongly recommend ordering physical samples before finalizing a color decision — we do this as standard practice on any metal roofing estimate.

You don't need a contractor on your roof to get a preliminary read. Here's what to look for:

From the ground (binoculars help)

• Curling or cupping shingles — edges turning up or centers buckling are a sign of age or moisture damage
• Missing shingles — gaps in the field, especially after wind events
• Visible dark patches — where granules have worn away, exposing the asphalt mat
• Moss or algae growth — indicates moisture retention and organic breakdown
• Sagging areas — suggests decking damage or structural issues below

From the gutters

• Heavy granule accumulation in gutters on a roof more than 10 years old — shingles are shedding their protective layer

From the attic

• Daylight visible through roof boards — immediate concern
• Water stains or streaks on rafters or sheathing
• Soft or spongy sheathing when pressed — rot has set in

Age

A standard 3-tab shingle roof over 20 years old is on borrowed time. Architectural shingles installed correctly can go 25–30 years. If you don't know the roof's age, check permit records at your town office — roof permits are public record in Vermont.

We offer free assessments with no obligation. A 20-minute visit from one of our crew will give you a clear picture.

Add 1–2 days if significant decking replacement is needed — we won't know the full extent until tear-off is complete, but we flag likely areas during the estimate.

Vermont weather caveat: We don't install in rain, and we coordinate carefully around forecast windows. We won't leave your house exposed overnight without full temporary coverage — a tarp secured properly is not a problem, but it's something we plan around, not something we leave to chance.

Total project timeline from signed contract to completion is typically 2–4 weeks, accounting for material lead time, permit if required, and crew scheduling. We give you a target window at signing and communicate any changes proactively.

Asphalt shingles are the most widely installed roofing material in Vermont — and for most homeowners, they're still the right answer. Here's why:

• Cost-effective. Lower material and labor cost than metal, tile, or slate. For a homeowner on a realistic budget, asphalt delivers a quality roof without overinvesting relative to the home's value.
• Repairability. A wind-damaged section, a wayward tree branch, or a flashing failure can be addressed without touching the rest of the roof. Metal roofs are more durable but harder and more expensive to repair when something does go wrong.
• Improved performance. Modern architectural (dimensional) shingles bear little resemblance to the 3-tab shingles from 30 years ago. Today's dimensional shingles are thicker, heavier, impact-resistant, and rated for 110–130 MPH winds. Premium lines include algae-resistant granules, which matter in Vermont's moist climate.
• Design flexibility. Asphalt comes in dozens of profiles and colors that complement Vermont's traditional home styles — from New Englander colonials to cape cods and farmhouses.
• Proven Vermont track record. Installed correctly — with proper ice-and-water shield, ventilation, and flashing — asphalt shingles perform reliably in Vermont's climate for 25–30 years.

A modern architectural asphalt shingle has four main layers, each serving a specific function:

1. Fiberglass mat core — the structural backbone, providing dimensional stability and resistance to tearing
2. Asphalt coating on both sides of the mat — provides waterproofing and bonds the surface granules to the shingle
3. Ceramic-coated mineral granules on the exposed surface — protect the asphalt from UV degradation (the primary cause of shingle aging) and give the shingle its color
4. Release film on the back — prevents shingles from sticking together in the bundle during storage and handling

The quality and weight of the asphalt layer is the primary determinant of shingle longevity — heavier shingles hold more asphalt and last longer. Premium shingles like Owens Corning's Duration series also include a SureNail reinforcement strip — a woven fabric layer in the nailing zone that dramatically improves fastener holding in high-wind events, which is relevant anywhere in Vermont.

Yes — but the details of installation matter more in Vermont than almost anywhere else.

Vermont's primary roofing challenges are ice dams, heavy snow loads, and freeze-thaw cycling. None of these disqualify asphalt shingles, but they do require specific installation practices:

• Ice-and-water shield must run from the eave edge a minimum of 24" past the interior wall line (Vermont code). On homes prone to ice dams or with lower slopes, we run it further — often 4–6 feet up the roof.
• Attic ventilation is critical. Without continuous soffit-to-ridge airflow, heat builds up in the attic, accelerates shingle aging, and promotes ice dam formation. We check ventilation on every job before we put a shingle on.
• Drip edge at eaves prevents water from wicking back under the shingle edge — a common failure point in freeze-thaw conditions.

Where asphalt has a legitimate disadvantage versus metal in Vermont is snow shedding. Standing seam metal sheds snow naturally due to its smooth surface. Asphalt holds snow, which increases the thermal load at the eaves and ice dam risk on lower-slope or poorly ventilated roofs. On a well-ventilated steep-pitch roof, this is much less of a factor.

Most of the work is ours — but a few things on your end make the job go smoother:

• Clear driveway access for crew vehicles and the dumpster or material staging area
• Move vehicles from the garage if possible — tear-off vibration transfers through the structure
• Remove wall hangings and items on upper-floor shelves — vibration from tear-off can knock things loose
• Cover attic items if the space is accessible and has anything stored in it
• Let your neighbors know — a full tear-off starts early and is loud. A quick heads-up goes a long way
• Notify your alarm company if you have a monitored security system — roof work can trigger motion sensors
• Plan to be home at the start so you can do a quick walkthrough with the crew lead and confirm any specific concerns

We handle everything else — permits, material delivery coordination, daily cleanup, and final site walkthrough. Our goal is to leave your property exactly as we found it, minus the old roof.

Warranty coverage depends on what failed and which warranty applies. Here's how to think through it:

Manufacturer warranty

Covers material defects — premature granule loss, cracking, or delamination not caused by an external event. Does not cover: wind damage (unless you have an enhanced wind endorsement), ice dam damage, improper installation, or lack of maintenance.

Forthright workmanship warranty

Forthright provides a 10-year workmanship warranty on all shingle roof installations and a 3-year workmanship warranty on standing seam metal. This covers installation errors for a period far exceeding the industry standard of 1–2 years. This is one of the most important questions to ask any contractor before signing — get it in writing.

Homeowner's insurance

Covers sudden storm damage — hail, wind, falling trees. Does not cover wear-and-tear, age-related failure, or deferred maintenance. After a major storm, always document damage with photos before any temporary repairs, and contact your insurer before authorizing full replacement — some policies require their adjuster to assess first.

We review all warranty documentation with clients at project closeout and handle product registration so your coverage is fully activated from day one.

A missing shingle exposes the underlayment — the secondary water barrier beneath. Modern synthetic underlayment will resist water for a period, but it is not designed as a permanent roofing layer.

In Vermont, the risk compounds quickly:

• Exposed underlayment in winter is subject to ice formation and freeze-thaw cycling that can lift adjacent shingles
• Wind can get under the exposed edge and peel back neighboring shingles, turning one missing shingle into several
• Water infiltration into the decking causes rot, which turns a shingle repair into a partial re-deck

A missing shingle after a wind event should be addressed within days, not weeks.

If you discover missing shingles and can't get service immediately, a temporary fix: lay a waterproof tarp over the affected area and secure it with furring strips screwed through the tarp into the roof deck at each side — not stapled into the shingles themselves. This protects the area without causing additional damage.

It depends on how much, and when.

Normal and expected

New shingles shed loose granules for the first few months after installation — you'll see them in your gutters after the first rain. This is a manufacturing characteristic, not a defect, and nothing to worry about.

Worth investigating

Significant granule loss on a roof that is 5–15 years old is a concern. Causes include:

• Hail impact — look for dime-to-quarter sized bare spots with a consistent pattern across the roof
• Manufacturing defect — accelerated loss across large areas of relatively new shingles
• Foot traffic or improper maintenance

Check the shingles themselves: if you can see the dark asphalt mat through the granule layer, the shingle's UV protection is compromised. Asphalt without granule cover dries out, becomes brittle, and cracks.

End of life signal

Heavy granule loss in gutters on a roof over 20 years old is a normal sign of age — the shingle is releasing its granules as the asphalt oxidizes. Not an emergency on its own, but a clear indicator that replacement planning should start.

A properly installed Vermont roof is a system, not just shingles. Every layer serves a purpose, and cutting corners on any one of them shortens the life of the whole assembly.

From the bottom up:

1. Roof decking (7/16" or 1/2" OSB or plywood) — the structural base. Any soft, rotted, or damaged sections are replaced during tear-off before anything goes on top.
2. Drip edge — metal flashing installed at eaves and rakes that directs water away from the fascia and prevents wicking.
3. Ice-and-water shield — self-adhering waterproof membrane applied at eaves (minimum 24" past interior wall per Vermont code), in all valleys, and around every penetration. This is the most critical Vermont-specific component.
4. Synthetic underlayment — covers the rest of the roof deck as a secondary water barrier and slip surface for installation.
5. Field shingles — installed in overlapping courses from eave to ridge per manufacturer specifications and local code.
6. Flashing — step flashing at all wall/roof intersections, counter flashing at chimneys, pipe boots at penetrations. This is where most roof leaks originate when they fail.
7. Ridge cap shingles — specifically designed shingles (not cut field shingles) that seal the ridge and complement the overall profile.
8. Ridge vent — installed at the peak, combined with soffit vents, to create continuous attic airflow. This keeps the attic cold in winter, reduces ice dam risk, and extends shingle life by preventing heat buildup.

Every one of these components is included in a Forthright roof replacement. We don't skip steps — and we're happy to walk through the spec with you before we start.
