How to prepare your roof for winter in Lakewood

A Lakewood winter does its damage slowly. Snow sits on the roof, melts a little on a sunny afternoon, refreezes at the eaves overnight, and repeats the cycle until water finds a way under the shingles. The roof that survives winter best is the one that went into it with clean gutters, sound flashing, and an attic that can breathe. This is the fall checklist that gets it there.

Why Lakewood roofs take a beating every winter

Lakewood sits at the edge of the Front Range, where winter is not one long freeze but a long series of freeze-thaw cycles. Snow loads to the City’s 30 psf design ground snow load. Daytime sun melts the snow on the upper roof; the water runs down to the colder eaves and refreezes; the ice builds into a dam; and the next melt has nowhere to go but under the shingles. That cycle, repeated all winter, is what ice dams are — and it is why a roof that looked fine in October can be leaking by February.

The housing stock makes it worse. The median Lakewood home was built in 1977, and 1960–79 construction is 40.2% of the city’s housing (U.S. Census Bureau, American Community Survey 2024 5-year). Many of those homes have ventilation and insulation that predate modern practice, which means warm attic air melts roof snow from below — the exact condition that builds ice dams.

Start with a winter roof inspection in Lakewood

Book the inspection in October, before the first lasting snow. The inspector checks what winter will attack first: flashing at chimneys, valleys, and walls; pipe boots and vents; ridge caps; and the decking where it is visible. They also check the attic, because attic temperature is what decides whether snow melts from below. If the attic is warm and the ventilation is poor, the roof will build ice dams no matter how new the shingles are.

The inspection also sets the baseline for spring. A written assessment with photos, taken in October, is the record you will compare against after hail season. See our roof inspection page and our guide to how often to schedule an inspection.

Clear gutters and downspouts before the first freeze

Gutters are the most overlooked part of winter preparation, and the most consequential. A gutter full of leaves and granules cannot drain, so the first melt freezes in place, the gutter fills with ice, and the water backs up under the eaves. Clear the gutters and downspouts in October, after the leaves are down, and check that downspouts discharge away from the foundation.

While you are there, look at what the gutters are telling you. Heavy granule deposits mean the shingle surface is wearing, and dents in the gutter are the signature of the last hail season. Both are worth noting for the inspection. If gutters need work, see our gutter installation and gutter repair pages — gutters are roofing-adjacent work for us, and they matter most in winter.

How to prevent ice dams in Lakewood

Ice dams are a ventilation and insulation problem before they are a roofing problem. Warm air leaking into the attic melts snow on the upper roof; the water refreezes at the cold eaves; the dam grows. The fix is to keep the attic cold: seal air leaks from the living space, make sure insulation is even and complete, and make sure intake and exhaust ventilation are balanced so cold air moves through the attic. Our roof ventilation and ice dams page explains the whole system.

Two things worth knowing about Lakewood specifically. First, the City’s adopted code does not require an ice barrier under the shingles — January mean temperatures here run about 32–33°F, above the code trigger — so the roof’s defence against ice dams is ventilation and flashing, not a membrane. Second, heat cables and roof rakes are stopgaps, not solutions: they manage the symptom while the attic stays warm. Fix the attic, and the dams mostly stop forming.

Winter roof maintenance checklist for Lakewood homeowners

• October inspection. Flashing, boots, vents, ridge caps, and an attic check. Written assessment with photos.
• Clean gutters and downspouts. After the leaves are down, before the first freeze. Check discharge direction.
• Trim overhanging branches. A limb heavy with snow can break onto the roof, and branches that rub the shingles wear them through.
• Check attic ventilation. Ridge and soffit vents clear, insulation even, no warm air leaking up from the living space.
• Look for interior signs. Ceiling stains, peeling paint near the eaves, and musty smells in the attic are ice-dam warnings.
• Know the snow-load limit. Lakewood’s design ground snow load is 30 psf. If snow is piling unusually deep, do not climb up to clear it yourself — call a professional.

Roof snow damage prevention in Lakewood

Snow itself rarely collapses a Lakewood roof — the 30 psf design load is generous for a typical Front Range winter — but snow causes damage in quieter ways. It hides hail bruises and cracked shingles until spring, it adds weight to gutters that are already full of ice, and it melts and refreezes in the valleys where flashing is weakest. The prevention is the same as the preparation: keep water moving off the roof, keep the attic cold, and do not let snow sit against the eaves for weeks.

If you use a roof rake, use it from the ground and only on the lower few feet of the roof, and never use a metal rake or a shovel on the shingles themselves. A scratched shingle is a shingle that will fail early. And never climb onto a snow-covered roof: you cannot see the ice, the footing is unreliable, and a fall from a two-storey Lakewood home is a serious injury.

Common mistakes we see every November

• Waiting for the first snow to think about the roof. By then, the roofer’s schedule is full and the gutters are already freezing.
• Cleaning the gutters but not checking the downspouts. A clear gutter with a blocked downspout is still a blocked gutter.
• Sealing the attic vents to “keep the heat in.” Blocked ventilation makes the attic warmer, which makes ice dams worse, not better.
• Chipping ice off the eaves with a hammer or shovel. You will damage the shingles and the flashing, and the dam will come back.
• Ignoring a ceiling stain until spring. A stain in January is water getting in now. It does not wait for the thaw.

When to call a professional

Call a roofer in October for the pre-winter inspection, and call right away in winter if you see a ceiling stain, a sagging gutter full of ice, or water running down an interior wall. Those are not wait-until-spring problems. Call (720) 817-3348 to book a fall inspection, or if winter has already found a weakness. Roof Authority LLC works on residential roofs across Lakewood, including Kendrick Lake and Morse Park, and our roof maintenance page covers the ongoing work that keeps a roof winter-ready.

Frequently Asked Questions

How do I prepare my roof for winter in Lakewood?

Book an inspection in October, clean the gutters and downspouts before the first freeze, check attic ventilation, trim overhanging branches, and look for interior signs of ice dams such as ceiling stains near the eaves.

Does Lakewood require an ice barrier on roofs?

No. Lakewood adopted code does not require an ice barrier, because January mean temperatures run about 32-33 F, above the code trigger. Ice dams still happen here, and the defence is ventilation, insulation, and flashing.

How do I prevent ice dams on my Lakewood roof?

Keep the attic cold: seal air leaks from the living space, keep insulation even, and make sure intake and exhaust ventilation are balanced. Heat cables and roof rakes manage the symptom, not the cause.

When should I get my roof inspected before winter?

In October, before the first lasting snow. The inspection checks flashing, boots, vents, and ridge caps, and sets a photo baseline for spring.

Is it safe to remove snow from my roof myself?

Use a roof rake from the ground on the lower few feet only, and never use a metal rake or shovel on the shingles. Never climb onto a snow-covered roof.
