Hey everyone, it\u2019s Jake here from your go-to wood shingles supplier \u2014 and let\u2019s cut to the chase: I get this question every single winter, usually from roofers, homeowners, and even property managers staring at snow piling up on sloped roofs. \u201cWill this heavy white stuff wreck my wood shingles? What about that ice that forms when temperatures swing above and below freezing?\u201d Today, I\u2019m breaking this down real \u2014 no fancy jargon, just the straight facts I\u2019ve picked up working with wood shingles for over 10 years. Wood Shingles<\/a><\/p>\n

<\/p>\n

First off, let\u2019s get one thing clear: not all snow and ice damage is the same. A lot of people mix up \u201clight, fluffy snow\u201d with \u201cwet, packed snow\u201d or \u201cice dams,\u201d and that\u2019s where mistakes happen. As a supplier, I\u2019ve seen both small, fixable issues and big, expensive replacements \u2014 mostly because someone didn\u2019t understand the difference between harmless winter buildup and the stuff that actually does damage. Let\u2019s start with the basics of how wood shingles are built, because that\u2019s key here. Most quality wood shingles (the ones we sell, anyway) are pressure-treated or naturally durable \u2014 cedar, redwood, maybe pine that\u2019s been coated with a weatherproof sealant. They\u2019re not invincible, but they\u2019re built to handle a lot, especially when installed right.<\/p>\n

Light, dry snow \u2014 like the stuff you get when it\u2019s 20\u00b0F or below, with low humidity \u2014 is actually not a big problem. It\u2019s light, it blows off easily, and it doesn\u2019t put that much pressure on the shingles. I\u2019ve had customers tell me they left 12 inches of that powdery snow on their roofs all winter, and when they cleared it come spring, the shingles looked almost exactly like they did in November. Why? Dry snow has a lot of air pockets, so it\u2019s not dense at all \u2014 think of comparing a bag of packing peanuts to a bag of bricks. That said, I don\u2019t recommend leaving snow on there forever, but it\u2019s rarely an emergency.<\/p>\n

The trouble starts when snow gets wet. Wet snow is way heavier \u2014 like, three to five times heavier than dry snow. That\u2019s the stuff you get when temperatures hover around freezing, where snow melts a little during the day and refreezes at night, turning into slush that packs down tight on roof slopes. I remember a job last year in a small town up north: a guy called me panicking, saying his roof sagged a little after a week of that wet, heavy snow. When we sent a roofer out, he measured the load \u2014 that wet snow was pushing 25 pounds per square foot, and most residential roofs are designed for a max of 20 to 30 pounds per square foot, depending on the pitch. Wait, but why does that matter for wood shingles specifically, not just the roof structure? Because that constant, heavy pressure from packed wet snow can make shingles warp, curl at the edges, or even crack if the roof has low spots where water pools. Those curled edges are a whole other problem \u2014 once they lift, water can get under the shingles, which leads to rot before you know it.<\/p>\n

Now, the big one that everyone talks about: ice dams. If you\u2019ve lived somewhere with harsh winters, you\u2019ve seen \u2019em \u2014 those thick, icicles hanging off your gutters, and the big buildup of ice along the eaves. Let\u2019s keep it simple on why ice dams form, because there\u2019s no need for a physics lecture. Ice dams happen when warm air from inside your attic melts snow on the upper part of your roof, and that melted water runs down to the cold eaves (where there\u2019s no warm air seeping through) and refreezes. That refrozen ice blocks the next layer of melting snow, so the water has nowhere to go \u2014 it backs up under the shingles. And that\u2019s where the real damage kicks in.<\/p>\n

I\u2019ve seen first-hand how ice ruins wood shingles. The water that backs up is constant, seeping through the smallest gaps in the shingle\u2019s seal. Over time, that moisture makes the wood swell, then shrink when it freezes, then swell again \u2014 that cycle is a death sentence for untreated or poorly sealed shingles. The edges split, the surface cracks, and before you know it, you have to replace half the roof. One trick I tell all my customers about ice dams? They\u2019re not just a winter problem \u2014 when that ice finally melts in spring, the sudden rush of water can blast the already weakened shingle edges right off the roof. I had a customer last year who came home from a weekend trip to find 20 or 30 shingles gone, scattered in his yard \u2014 all because of an ice dam he didn\u2019t notice until it was too late.<\/p>\n

Wait, but let\u2019s not blame all of this on snow and ice alone. Most of the time, damage happens because of pre-existing issues with the shingles or the roof, not the winter weather itself. For example, if your wood shingles are old and have never been resealed, they\u2019re way more likely to absorb that melted water. Or if your attic is poorly ventilated \u2014 that\u2019s a big one \u2014 warm air gets trapped, which is exactly what causes ice dams in the first place. I\u2019ve had people call me saying \u201cmy wood shingles are ruined by snow\u201d when really, it was a gap in their attic insulation that let heat escape. That\u2019s why I always tell customers: don\u2019t just blame the weather, check the basics first.<\/p>\n

Now, what can you actually do to protect your wood shingles from snow and ice damage? Let\u2019s get practical, since that\u2019s what everyone wants. First, if you have a steep roof, you might not even need to clear light snow \u2014 but if you have a low-pitch roof (under 4\/12, which means it rises 4 feet for every 12 feet of horizontal length), packed snow is way more likely to pool. So go slow when you clear it: use a plastic roof rake, not a metal shovel \u2014 metal can scratch or gouge the shingles, which is a whole other way to let water in. Never climb on the roof yourself, by the way \u2014 hire a pro, it\u2019s not worth the fall.<\/p>\n

For ice dams, prevention is key. Make sure your attic is properly ventilated and insulated \u2014 that stops warm air from melting the upper roof. Some customers use heating cables along the eaves, but I\u2019d recommend checking with a roofer first, because if they\u2019re installed wrong, they can actually damage shingles too. And if you do get ice forming, don\u2019t hack at it with a hammer \u2014 that\u2019s another way to crack shingles. Wait for it to melt naturally, or use a safe ice melt made for roofs (the kind that\u2019s not harsh on wood, like calcium chloride, not salt) if you need to speed it up a little.<\/p>\n

As a supplier, I also want to tell you that not all wood shingles are created equal when it comes to winter damage. The cedar shingles we carry, for example, have natural oils that make them more resistant to moisture and freeze-thaw cycles than, say, untreated pine. We also recommend a marine-grade sealant for anyone in areas with heavy snow or ice, because that extra layer keeps water out without making the wood feel heavy or weird. I\u2019ve had customers tell me their cedar shingles with sealant have gone 15+ years with almost no winter damage, while their old untreated pine shingles needed replacement every 5 years. That\u2019s a big difference, right?<\/p>\n

Wait, let\u2019s address a common myth I hear all the time: \u201cWood shingles are too fragile for snowy climates.\u201d No, that\u2019s not true. They\u2019re actually one of the most durable roofing materials out there, as long as you get the right type and maintain them properly. I supply wood shingles to homes in Minnesota, Maine, even parts of Canada where winter brings 2 feet of snow and temperatures drop to -30\u00b0F \u2014 and most of those roofs are still going strong after 20 years. The problem isn\u2019t the shingles themselves, it\u2019s when people buy the cheap, thin shingles from the big-box store that don\u2019t have proper treatment, or skip the maintenance, or wait too long to clear packed snow and ice.<\/p>\n

Another thing I want to mention: ice damage isn\u2019t just about the water. When ice forms on shingles, it expands \u2014 that\u2019s physics 101, water expands when it freezes. So if ice gets into any tiny crack or gap in the wood, it pushes that crack wider over time. That\u2019s why a small scratch or split in a shingle in fall can turn into a big hole by spring, all because of that freeze-thaw cycle. That\u2019s why regular inspections (twice a year, before winter and after) are so important. I always send a free quick tip sheet with every order that has a checklist for winter maintenance \u2014 things like checking for lifted shingle edges, clearing debris from your gutters (clogged gutters make ice dams way worse!), and making sure your attic vents aren\u2019t blocked by insulation.<\/p>\n

Let\u2019s wrap this up with what I want you to take away. Can snow and ice damage wood shingles? Yep, absolutely \u2014 but only when it\u2019s the wet, packed snow or ice dams, not the light fluffy stuff that blows off. And most of that damage is preventable, right? Choosing the right type of wood shingle (like the durable, treated ones we supply), maintaining your roof, clearing snow safely, and stopping ice dams before they start will go a long way toward keeping your shingles in good shape for decades.<\/p>\n
