The Hidden Dangers of Snow Accumulation on Your Roof: A Guide for Cumberland, MD Homeowners
There's something beautiful about waking up to a fresh blanket of snow covering Cumberland. The hills around Allegany County look like a winter postcard, and that layer of white on your roof adds to the charm. But here's the thing, while it might look peaceful up there, snow accumulation can actually create some serious problems for your home.
Let's talk about what's really happening on your roof this winter and how you can keep your home safe and sound.
Snow Is Heavier Than You'd Think
Here's something that surprises most homeowners: snow is heavy. That fluffy stuff that just fell? It weighs about 7 pounds per cubic foot. But as it sits there and gets packed down, or worse, when it gets wet, it can weigh up to 20 pounds per cubic foot. And ice? That's a whopping 57 pounds per cubic foot.
To put that in perspective, if you've got a typical 1,500 square foot roof with just one foot of packed snow on it, you're looking at over 15 tons sitting up there. That's like parking 10 cars on your roof! Some of the older homes in Cumberland's historic neighborhoods weren't necessarily built with that kind of weight in mind, especially when we get hit with storm after storm without much melting in between.
Ice Dams: The Sneaky Problem
If you've lived in Cumberland for any length of time, you know our winter temperatures love to bounce around. One day it's 40 degrees, the next it's 20. While that variability is just part of life in the Allegany Highlands, it creates perfect conditions for something called ice dams.
Here's how it happens: Heat from inside your home rises into the attic and warms up your roof. That warmth melts the snow up top, and the water trickles down toward your gutters. But when it reaches the colder edges of your roof, it freezes again. Over time, you get a ridge of ice that acts like a dam, and water starts backing up under your shingles.
The result? Water where it definitely shouldn't be:
- Stains appearing on your ceilings and walls
- Paint starting to peel or plaster getting damaged
- Insulation getting soaked (which means higher heating bills)
- Potential mold growth in your attic
- Shingles getting loosened or damaged
Not exactly the kind of indoor water feature anyone wants!
What to Watch For
You don't need to be a roofing expert to spot potential trouble. Just keep an eye out for these warning signs:
Sagging or uneven rooflines - This is the big one. If your roof looks like it's drooping or your ceiling seems bowed, that's serious. Time to call in the pros right away.
Water stains inside - Those brown spots on your ceiling or walls? They're telling you water is getting in somewhere.
Icicles hanging from your gutters - Sure, they're pretty, but big icicles usually mean you've got ice dams forming or your attic insulation needs some attention.
Strange creaking or cracking sounds - Your house talks to you. If it's making unusual noises during or after a snowstorm, it might be telling you it's under stress.
Why Cumberland Weather Makes Things Tricky
Living in Cumberland means dealing with that freeze-thaw cycle we mentioned earlier. When temperatures swing above and below freezing, water gets into tiny cracks, freezes overnight, and expands. It's like nature's way of prying things apart, slowly damaging flashing, loosening shingles, and creating openings for more water to sneak in. Over the course of a winter, this cycle can do a real number on your roof.
The Right Way (and Wrong Way) to Remove Snow
When you're looking at all that snow piled up on your roof, your first instinct might be to grab a ladder and start shoveling. We totally understand the urge, but please don't!
Here's the safe approach:
Stay off your roof - Seriously, icy roofs and ladders are a dangerous combination. It's not worth the risk.
Use a roof rake from the ground - If you've got a roof rake, you can carefully pull snow down from the ground level. Just pull straight down and avoid yanking at angles, which can tear up your shingles.
Work in small sections - Don't try to clear the whole roof at once. Taking it section by section is easier on both you and your roof structure.
Leave a little behind - Keep about an inch of snow on the roof to protect your shingles from the rake itself.
When It's Time to Call for Help
Some situations just need a professional touch. Give E&E Exteriors a call if:
- You see any sagging or structural concerns (don't wait on this one!)
- Ice dams are causing leaks inside your home
- You've got more than 2 feet of snow up there
- We've had multiple storms without much melting between them
- Your roof is getting up there in age (15+ years) and you're worried about the load
You've got a flat roof or complex roofline that's not draining well

An Ounce of Prevention
You know what's better than dealing with winter roof problems? Not having them in the first place! Here are some things that really make a difference:
Good attic insulation and ventilation - This is huge. Proper insulation keeps your heat where it belongs (inside your living space), and good ventilation keeps your attic cold so snow doesn't melt on the roof surface. This combo is your best defense against ice dams.
Clean gutters - Before winter hits, make sure your gutters are clear. They need to be able to do their job when snow starts melting.
Pre-winter roof check - Having someone take a look at your roof before the snow flies means you can fix small problems before they become big, expensive problems.
Trim those tree branches - Any branches hanging over your roof are just waiting to come down when loaded with snow and ice. Better to trim them now.
Let's Talk Before There's a Problem
Most folks wait until they see water stains on the ceiling before they call. By that point, the damage has already spread to places you can't see, insulation, wood framing, maybe even electrical systems. It's always less expensive (and less stressful!) to prevent problems than to fix them after the fact.
