Why Do Properties in Bedford, NH Need Snow Guards?
December 17, 2025
If you own a home or business in Bedford, New Hampshire, winter can bring heavy snow and dangerous roof problems. This part of the New Hampshire coast gets big snow events from nor’easters and coastal storms. These storms can dump a lot of snow all at once and make the snow on your roof push, slide, or fall suddenly. Snow guards help stop snow and ice from sliding off roofs and hurting people or property below.
Data from the ASCE shows that ground snow loads (how heavy snow can be) in New Hampshire require careful planning for roofs to stay safe under snow weight.
What Is the Main Safety Benefit of Snow Guards?
The biggest reason to install snow guards is safety. Without them, large chunks of snow and ice can slide off a roof all at once. This can hit people walking below, cars in driveways, decks, or bushes near a home.
Snow guards slow the snow down and hold it in place so it melts safely. This makes sidewalks, driveways, patios, and places where people walk much safer during the deep winter months.
How Do Snow Guards Protect Your Property?
Snow guards don’t just help people — they also help your building and landscaping. Big snow slides can pull gutters off the edge of a roof or bend the edges of a roof. Snow that slides off suddenly can break outdoor lights, damage shrubs, or crack walkways.
By holding snow on the roof and helping it melt slowly, snow guards make sure the snow drains in a controlled way. This reduces the chance of ice dams forming — frozen blocks of ice that can push on your roof and walls.
How Heavy Is Snow in Bedford, NH?
Bedford gets real snow every winter. In some winters, snow totals across New Hampshire can be above 90 inches for the season. Even near the coast, towns like Portsmouth and Bedford see several inches of snow during the first storms of the winter. Because the snow keeps coming all season long, it’s important that snow guards are strong enough for high snow weight.
Where Should Snow Guards Be Placed on Your Roof?
Snow guards should be put in specific spots so they do the best job possible.
Key spots include:
- Above walkways
- Over doorways
- Near driveways
- Above places where people stand a lot (like decks)
Most installers place snow guards within about three feet of the edge of the roof to help catch snow before it slides off.
Does Roof Type Matter for Snow Guards?
Yes — the type of roof makes a big difference.
Metal Roofs
Metal roofs are very slippery. This means snow can slide off quickly once it starts to melt. Snow guards on metal roofs are super important. Some guards clamp on without drilling holes, which helps the metal expand and contract without damage. Others are pipe or fence‑style snow guards that hold heavy snow best.
Asphalt Shingles, Wood, or Tile
These surfaces have more friction than metal. This means they don’t shed snow as fast, but snow guards are still helpful. Often, pad‑style snow guards are used for these roof types.
For any roof steeper than about 22 degrees, more guards are usually needed to stop snow from running off suddenly.
How Should Snow Guards Be Installed and Meet Rules?
Snow guards must be installed on clean, dry, frost‑free roofs and should be made from non‑rusting materials to last many winters.
It’s also smart to talk to the Town of Bedford Building Department to check if there are local requirements for snow retention systems, especially for bigger buildings or structures near public sidewalks or streets. Local codes sometimes require special systems for safety.
Can Snow Guards Look Good on My House?
Yes! Snow guards come in a variety of styles and colors. This means they can match your roof so they don’t stand out. A well‑chosen snow guard system protects your home and can even help your house look better.
