Christmas Decorations on Your Roof: A Myrtle Beach Roofer's Guide

By the Weather Shield Roofing team · Published November 2, 2026

The short answer

• Yes, you can put decorations on a Myrtle Beach roof. The rule is simple: nothing goes through the roof surface.
• Inflatables and Santa figures are sails. Tie them to ground stakes, porch posts or seam clamps, never to a nail in the shingles.
• On shingles, use clips on the shingle edge or the gutter. Skip nails, screws and staples. A cold morning makes shingles brittle.
• On standing seam metal, use clamps that grip the seam. On exposed-fastener metal, use magnetic clips on the screw heads. No new screws.
• On flat or low-slope sections, use weighted bases on a protective mat. Keep weight off drains and out of standing water.
• Projector lights, wreaths on walls and figures on the lawn give the look with nothing on the roof at all.
• Take it all down after New Year's and check for lifted shingles, holes, scratches and bent gutters. Call us if you find any.

Roof decorations in Myrtle Beach by the numbers

What can go on a roof, and how to attach it

Search this question and you get idea boards, retailer listings, video how-tos and a few roofer posts. Here is the same list from the roof's point of view: what each decoration is, where it can go, and what it does to the surface under it.

Clip types are real products: shingle clips, gutter clips and all-in-one clips for C7 and C9 bulbs (Christmas Lights Etc). Seam clamps for metal roofs are the same hardware used for snow guards and solar mounts (Sheffield Metals). The rest of the table is general roofing practice, not a figure from a study.

Weight, wind and where to tie down

Myrtle Beach winters are mild, but they are not calm. The numbers below are from the National Weather Service station at North Myrtle Beach, read from the daily wind columns of its monthly climate reports (November 2025, December 2025).

• The National Weather Service station at North Myrtle Beach recorded a peak gust of 41 mph in November 2025 and again in December 2025.
• In December 2025 the daily peak gust reached 25 mph or more on 14 days, and 30 mph or more on 5 days. November 2025 had 10 days at 25 mph or more.
• The monthly average wind sounds tame, about 6 mph both months, from the daily averages in the same reports. The gusts are what pull a decoration loose.
• Horry County's building code wind lines run from 140 mph in the west to 150 mph along the beaches. Your roof is built for that. A plastic Santa is not.
• An inflatable is a bag of air with a fan. In a gust it acts like a sail, and the only thing holding it is whatever you tied it to.

The county wind lines come from the SC Building Codes Council map for Horry County. For what those lines mean for a roof, see our SC wind zone roofing guide.

Where to anchor, by surface

• On the lawn: stakes and sandbags

  The safest spot for an inflatable is the ground. Use the stakes that came with it, or longer ones in sandy soil. Add a sandbag over each foot. Sand here drains fast and stakes loosen when it is dry.

• On a porch or deck: posts and rails

  Strap to a post, not a rail cap. Use ratchet straps or rope with a knot you can undo, and pad the strap where it crosses a painted surface.

• On a shingle roof: the chimney, the ridge vent zone, or nothing

  Loop straps around a brick chimney with corner pads. Never drive a stake, nail or screw into the shingle field. If there is no chimney, keep the inflatable on the ground.

• On a standing seam metal roof: seam clamps

  Clamps that grip the raised seam hold without a single hole. Sheffield Metals, a metal roof maker, points to this kind of non-penetrating mount for anything added to a standing seam roof.

• On a flat or low-slope roof: weighted bases on a mat

  Set a rubber mat or carpet scrap under a weighted base. Keep the weight off drains and scuppers. Do not use concrete blocks straight on the membrane.

• Every night the forecast says wind

  Unplug the fan and let the inflatable lie down, or bring it in. A deflated Santa cannot sail. Watch the forecast for gusts over 25 mph.

Asphalt shingle roofs: clips, cold mornings and the sealant strip

Architectural shingles hold a decoration fine as long as you work with the shingle, not through it. The cold-weather points come from the Asphalt Roofing Manufacturers Association, the shingle makers' trade group.

• Use clips that hook the bottom edge of a shingle or the gutter lip. Christmas light sellers make shingle clips, gutter clips and all-in-one clips for C7 and C9 bulbs.
• No staples, no nails, no screws. Christmas Lights Etc, a lights retailer, says plainly that staples and nails can damage your home and your lights.
• Cold makes shingles stiff. The Asphalt Roofing Manufacturers Association says shingles become less flexible as temperature drops and may crack when handled.
• Decorate on a mild afternoon, not a frosty morning. December 2025 had nine mornings at or below freezing at North Myrtle Beach.
• Walk as little as possible. ARMA warns that roof traffic in cold weather can break the sealant bond between shingle courses, and curved or buckled shingles break underfoot.
• Do not pry up a shingle tab to slide a clip under it. The sealant strip is what holds that shingle in a gust, and once broken it may not re-seal on its own.
• Keep figures and bases off the shingle field. If a sleigh has to sit on the roof, put it on a wide base at the eave with straps to a chimney or the deck below.

Metal roofs: standing seam and exposed fastener

Metal roofs are common on newer coastal homes here. There are two kinds, and the rules differ. The system descriptions below come from Sheffield Metals, a metal roof panel maker, and its maintenance guide.

• Standing seam (raised seams, no visible screws)

  Use clamps that grip the seam. Sheffield Metals describes standing seam as a concealed-fastener system with no holes in the panels, and names non-penetrating clamps as the way to mount solar, snow guards and other add-ons. Light clips that pinch the seam work the same way.

• Exposed fastener (screws through the panel)

  Use magnetic clips on the screw heads and ribs, or clips on the eave trim. Sheffield says exposed-fastener panels already carry many holes and that leaks at those holes are the system's most common problem. Do not add more.

• Never drive a new screw

  A screw through a panel is a permanent hole. Sheffield's maintenance guide says any penetration added to a metal roof should be handled by a professional roofing contractor.

• Protect the paint

  Dragging a strap, a ladder or a sleigh base across a painted panel scratches the finish. Sheffield's guide notes that scratches and scuffs on the paint system are typically not covered by the maker. Pad every contact point.

• Oil canning is not your fault

  Wavy flat areas on a metal panel are called oil canning. Sheffield links it to restricted thermal movement of the panel, which is one more reason to keep anything you add at the seams and eaves rather than pinned to the field of a panel.

• Metal is slick

  Dew, frost and salt haze make a metal roof slippery. Do not walk on a metal roof to decorate it; work from a ladder at the eave or from the ground with a pole.

Found a screw hole, a loose panel or a long scratch after the holidays? That is what our metal roof repair service is for. For the differences between the two systems on a coastal house, see standing seam vs corrugated metal.

Flat and low-slope sections: no punctures, weighted bases, no ponding

Porch roofs, additions and many condo buildings along the Strand have flat or low-slope sections covered by a membrane. A membrane forgives nothing sharp. These are the rules that keep a low-slope roof watertight through December.

• No punctures. A TPO, PVC or modified bitumen membrane is a set of sheets joined at lap seams, and the field and the seams are both the roof. A stake, screw or dropped bracket opens it.
• Use weighted bases on a mat. A rubber mat or a scrap of carpet under each base spreads the load and keeps grit from grinding into the membrane.
• Keep everything away from drains and scuppers. A base, a cord or a loose net over a drain backs water up onto the roof.
• Watch for ponding. Water that sits more than a day or two after rain is a roof problem on its own. Decorations that trap leaves make it worse.
• Mind the seams. Set bases on the field of the sheet, not across a lap seam, where the extra weight and movement works at the bond.
• Lift, do not drag. Dragging a sleigh or a weighted base across the membrane scuffs the top layer.

One more metal note that applies here: Sheffield says exposed-fastener metal needs at least a 3/12 slope so water sheds instead of pooling on the screw holes. If your low-slope section is screwed-down metal, keep every decoration off it.

Gutters and fascia: light loads only

• Gutter clips hang lights from the lip without a hole. They are made for C7, C9 and icicle strings. Weight stays light.
• Do not hang inflatables, garland rolls or figures from the gutter. Gutters here are held by spikes or hidden hangers meant for water, not for a sail.
• Keep extension cords out of downspouts. A cord in a downspout blocks the next rain and a December storm here can drop close to an inch in a day.
• Clean the gutters before you clip to them. Full gutters are heavier, and you will be back on the ladder in January anyway.
• Fascia hooks are fine for a wreath on a gable, as long as they screw into the fascia board and not into the drip edge or shingles.

The rain figure is from the same NWS report: the biggest one-day total at North Myrtle Beach in December 2025 was 0.95 inch (NWS F-6, December 2025).

Lights, cords and outlets, briefly

This guide is about decorations, so we keep the lights short. Two of the rules below are the CPSC's (Nov. 2024 holiday release): never string more than three incandescent sets together, and never overload an outlet. The rest is general outdoor-wiring and placement practice.

• The CPSC's rule for incandescent strings: never connect more than three sets end to end, and never overload an outlet. LED sets carry their own limit on the tag. Follow it.
• Plug outdoor strings and the inflatable's fan into an outdoor-rated outlet with ground-fault protection. If your exterior outlets are the old kind without a test button, an electrician can swap them.
• Use cords marked for outdoor use, and route them so they never cross a walkway, a gutter outlet or a downspout.
• Point C9 bulbs out or down so the socket drains. A socket that holds water on a roofline trips the circuit.
• Metal roof? Put the cord on the trim and clamps, never under a panel edge where it can chafe.
• A roofline string is a decoration, not a fastener. Never use it to steady a figure or an inflatable.

The no-roof-damage options

Plenty of well-decorated houses never put a thing on the roof. From the street, these read the same.

• Projector lights from the lawn. Snowflakes, stars or a full scene on the roof, with nothing touching it.
• A lit wreath on each window or gable, hung from a wall hook or a fascia hook.
• Santa, sleigh and reindeer on the lawn or across the front walk, staked where you can reach them.
• A column of inflatables along the driveway, each one tied to two stakes and a sandbag.
• Gutter-clipped lights along the roofline, which read as a lit roof from the street.
• Lit garland on the porch rail and columns, where you can plug it in at ground level.

Falls, fires and ladders

The injury and fire numbers are national, from the CPSC (and its 2014 breakdown) and the NFPA. The ladder rules are the American Ladder Institute's.

• The CPSC counts about 160 holiday decorating injuries a day in the US, and over 40% involve falls. About 14,800 people went to emergency departments in the 2021-22 season.
• In the CPSC's earlier breakdown, falls were 34% of decorating injuries, cuts 11% and back strains 10%.
• The NFPA counts an average of 835 US home fires a year that started with decorations other than trees, causing 3 deaths, 29 injuries and $18 million in damage.
• Ladder rules from the American Ladder Institute: firm, level ground; a duty rating above your weight plus tools; never stand on the top rung; keep three points of contact.
• Do not carry anything in your hands on the ladder. Hoist it on a rope after you are up, or pass it to a helper.
• Hire it out when the roof is steep, metal, two stories or wet. A pro display installer or a roofer with a harness is cheaper than a fall.

What decorations do to a roof, and what to check in January

A roof leak that shows up in January and only when it rains hard can trace back to a December fastener hole or a lifted shingle. When the decorations come down, look for these six things from the ground or a ladder, never from the roof itself.

• Fastener holes

  Any nail, screw or staple that went into shingles, a panel or a membrane. Each one needs sealing or a patch before spring rains.

• Lifted or torn shingle tabs

  Clips pulled hard, straps dragged or a figure slid off the roof. Lifted tabs lose their seal and go first in the next storm.

• Scratched or dented metal panels

  A scratch through the paint rusts from the edges. A dent at a seam can hold water. Both are worth a touch-up or a look.

• Bent or pulled gutters

  A gutter that sags or pulls away from the fascia after the holidays was carrying more than lights.

• Membrane scuffs, cuts or ponding

  On a flat section, look where bases sat and where cords ran. Standing water after a dry day means a drain or low spot needs attention.

• Debris and clogged drains

  Nets, cords and bases trap leaves. Clear every valley, gutter and scupper when the decorations come down.
