Rooftop Snow Removal

How Much Snow is Too Much Snow on Your Roof in Rochester, NY?

The main reason you should keep your rooftop as snow-free as possible is that it’s crucial for preventing ice dams from forming on your roof, so you don’t need Rooftop Snow Removal.

Ice dams can’t form without snow.  If you’re able to prevent ice dams, you’re far more likely to prevent your roof from leaking and damaging the inside of your home.

Another reason rooftop snow removal is so important is that it’s a good idea to keep all that excess weight off your roof.  As a rule of thumb, one square-foot of snow that’s one-inch in depth weighs about a pound.  If your roof has 12 inches of snow on it, that could easily amount to thousands of pounds of stress on your roof.  That’s not even counting the weight of any ice dams that may form as a result of leaving the snow on your roof; just one cubic foot of ice weighs 57 pounds, and a typical ice dam can weigh thousands of pounds.  Minimizing the stress placed on your roof is a great way to minimize the risk of leaking and cave-ins (the latter of which occur more frequently than you might think).

Weight of the Snow (Not ‘How Much’) Is What Matters

The critical factor in determining excessive snow loads on your roof isn’t the depth of the snow, it’s the weight.

That’s because wet snow is a whole lot heavier than dry, fluffy snow. In fact, six inches of wet snow is equal to the weight of about 38 inches of dry snow. That’s a huge difference!

The good news is that your roof is required by building codes to withstand the heaviest snows for your part of the country.

“Theoretically, if your roof is built to code, it’s built to support more than the normal load of snow and ice.

How to know if you’ve got wet or dry snow?  You back will let you know. Simply heft a few shovelfuls — you should be able to quickly tell. Plus, local weather forecasts should alert you if snow loads are becoming excessive.

Your Doors Will Tell You If There’s Too Much Snow

Your interior doors are a really good clue. If they begin to stick, that signals there’s enough weight on the center structure of the house to distort the door frame (yikes!).

Ignore doors on exterior walls but check interior doors leading to second-floor bedrooms, closets, and attics in the center of your home. Also, examine the drywall or plaster around the frames of these doors for visible cracks.

Homes that are most susceptible to roof cave-ins are those that underwent sloppy renovations. Improper removal of interior load-bearing walls is often responsible for catastrophic roof collapses from snow.

If You Decide the Snow Must Be Removed From Your Rooftop

Don’t do it yourself if it means getting on the roof.

“People die every year just climbing ladders. “Add ice and snow and you’re really asking for trouble.”

Instead, call a professional Rooftop Snow Removal Expert to safely do the job.

Check to make sure they are insured — that immediately sets them apart from inexperienced competitors.

For Rooftop Snow Removal Expect to pay $250 to $500 for most jobs. That’s because they need special gear, including sturdy extension ladders, properly anchored safety harnesses, and specialized snow and ice-removal tools.

Don’t expect (or demand) a bone-dry roof at job’s end. The goal is to remove “excessive” weight as opposed to all weight. Plus, any attempt to completely remove the bottom layer of ice will almost always result in irreparable damage to your roofing.

Tips for Getting Snow Off Your Rooftop From the Ground

If you have a small, one-story bungalow where the roof is just off the ground, taking matters into one’s own hands may be safe — if you can work entirely from the ground and have the right tools.

Long-handled snow rakes work great on freshly fallen snow, and at $45 they are relatively affordable. Look for models with sturdy telescoping handles and built-in rollers, which keep the blade safely above the shingles.

Other versions work by releasing the snow from underneath. These models slide between the roof and snow, allowing gravity and the snow’s own weight to do most of the work. These are more pricey, rising well above $100. But it’s a good idea to rethink their use. Eakes points out, “They tend to work their best on light, fluffy snow — the kind that probably doesn’t need to be removed in the first place.”

A couple of tips if you’re going to remove snow from the roof yourself:

1. You’ll need to anticipate where the snow and ice will fall as you pull it off your roof — you won’t want to pull a load of heavy, wet snow down on top of yourself or any helpers.

2. Remember, the goal isn’t to remove all visible snow and ice, but rather just enough to relieve the excessive load on the roof.
