Holiday decorating is one of the best parts of winter in every part of the world, same in Maryland. Lights, yard displays, and seasonal setups add a nice touch to a home. But there’s something many homeowners don’t realize until it’s too late: some holiday decorations can harm your roof if they’re placed the wrong way or in the wrong spot. A few little mistakes result in loose shingles, gutters clogged, or water finding their way to places they should not reach. A call to your roofing company is probably not on your Christmas wish list.
This guide breaks things down in clear, understandable steps to help with safe decoration and avoid any issues in the winter months.
Why Holiday Decorations Can Create Roof Trouble
Most roof issues around the holidays come from added weight, poor placement, or blocked drainage. These are simple things to prevent once you know what to avoid.
1. Heavy Inflatables Can Wear Down Shingles
Large inflatables may look fun, but they’re not for the roof. Their weight and movement can:
- Loosen shingles
- Rub off protective granules
- Add pressure to the older or weaker spots
- Hold snow and moisture in place
GAF indicates that inflatables are never to sit directly on the shingles.
Better choice: Place inflatables on the lawn or porch instead. They’re easier to fasten there, and they won’t weigh down the roof.
2. Holiday Lights Installed the Wrong Way Can Lift Shingles
Lights on their own are harmless-the problem is how they’re attached. Anything that gets nailed, stapled, or tucked under a shingle can lift it enough to let water slip in later.
GAF recommends plastic clips. These keep everything off the roofing surface.
Avoid:
- Staples, nails or screws
- Clips pushed under shingles
- Dragging light strings across shingles
Use instead:
- Gutter clips
- Eave clips
- Clips for brick or railings
If your gutters are already appearing uneven or loose, it’s best to get them checked before installing lights.
3. Decorations Can Block Gutters and Cause Water Backup
Even lights decorations-such as garlands or big bulbs-can potentially block the lip of the gutter or add extra weight. This, when the winter weather hits, can easily cause a water overflow or ice forming in wrong places.
Angi highlights that roofline garlands are getting more popular, making this issue more common.
Tip: Clean gutters before decorating. And if they already sag or hold water, schedule an inspection.
4. Walking on the Roof Can Crack Shingles in the Cold
Roofs in Maryland often collect frost, thin layers of ice, or wet leaves. Shingles also stiffen in cold weather, making them easier to crack.
Walking on the roof to hang decorations can lead to
- Broken shingles
- Loose granules
- Slip hazards
Safer plan: Use a ladder and stay on the edges you can reach without stepping onto the roof.
5. Screws and Fasteners Can Let Water In
Any decoration that needs to be drilled or screwed into the roof should be avoided. Even small holes can let water in once it snows or rains.
This includes:
- Wooden cutouts
- Santa/sleigh displays
- Signs
- Anchored projectors
Use only those that fix to gutters, railings, or even the ground.
How to Decorate Safely This Holiday Season
- Use plastic clips only: Skip nails, staples, or anything that attaches to shingles.
- Keep inflatables on the ground: They stay secure and don’t put stress on your roof.
- Clear gutters before decorating: This helps prevent winter backups.
- Avoid walking on the roof: Winter makes surfaces slick and shingles more fragile.
- Keep heavy items away from gutter lines: Extra weight can pull gutters loose.
- Check for loose shingles or sagging gutters: If something looks off, have it checked before decorating.
