Hang lights from clips made for your roof edge, gutter or fascia, never from nails or staples driven through roofing. Stay off tile roofs, because walking cracks tile. Set the ladder at a 4 to 1 angle, away from power lines, and never string more than three sets of incandescent lights together.
The lights are going up and you want the roof to come through the season unharmed. Here is what damages a roof, what does not, and how to do it safely.
Clip them to the edge of the house with clips made for that edge, work from a ladder, and stay off the roof surface.
The roof's job is to shed water. Anything that punches a hole in it, or wears it down, works against that. Most holiday-light damage comes from two things: fasteners driven through roofing, and feet on the roof. Both are easy to avoid. Here is the who, what, when and where in plain terms:
IBHS, the Insurance Institute for Business & Home Safety, says sunshine can drive roof temperatures over 200°F. A Florida roof in a mild December can still be hot enough to be hard to handle on a sunny afternoon. Clipping at the edge keeps you off that surface. For tile owners it also keeps you off a roof that can crack under your weight. See our guide on walking on a tile roof without cracking tiles.
Coastline can inspect the roof and send a written photo report. On a tile roof, Josh usually flies a drone over it first so nobody has to walk on the tile. Coastline Roofing works all over Florida (license CCC1331076).
None of these needs a big accident. Small habits cause the problems.
A nail or staple through a shingle, a tile or a roof edge is a hole in the roof covering. Pulling it out in January leaves the hole behind. It may not leak right away. Our guide on nail pops shows how fasteners affect a shingle.
Tile can crack under foot. Tile can crack under foot, and the Tile Roofing Institute (TRI) says tile roofs should be installed by a certified professional roofing contractor. Josh usually flies a drone over a tile roof first, so no one has to walk on it to find out what is wrong.
IBHS describes granules as coated rocks that protect the fiberglass from UV rays, and says rain and age loosen them. Boots grind them off. Where granules are gone, the shingle ages faster. See granules in the gutters.
IBHS says the sealant that holds shingle tabs down weakens enough after 7 to 10 years to cut wind resistance. On a worn roof the lights are not the problem. The climb is. Our guide on signs a roof has 2 to 3 years left helps you judge.
The U.S. Consumer Product Safety Commission says never string together more than three sets of incandescent lights and never overload electrical outlets. Check the label on any other type of light for its limit.
NIOSH reports that about 40 percent of ladder fall cases involve the ladder sliding at the base, and says many ladder injuries happen at home. The roof is not the only fall risk. The ladder you used to avoid the roof is another.
Work from the ground or a ladder at the edge. Use clips. Test the lights first. Set the ladder right.
Light the eave, the gutter line or the fascia rather than the ridge or the slope. The lower the line, the less risk to you and to the roof.
Look for clips labeled for your gutter, shingle edge or fascia, and read the package to see which roof type each fits. Do not use nails, staples, screws or hooks that go through the roofing.
Plug them in on the ground and replace any dead or frayed strand before it goes up. Never connect more than three sets of incandescent lights together, per the CPSC, and do not overload outlets.
OSHA says to set a ladder at a 4 to 1 angle, one foot out at the base for every four feet up to the eave, and when you step onto a roof the ladder should extend three feet above the roof edge. NIOSH advises about a 75 degree angle for extension ladders. Use level, firm ground and have a helper hold the base.
OSHA says to treat every overhead power line as live, and not to use a metal ladder near power lines or energized equipment. Carry the ladder flat and keep the light strings off the lines.
Pop the clips off with your hand and do not yank. Then check what was left behind: a stray nail or staple, a lifted tab, a cracked tile. Fix those before the next rain.
If your roof is tile, steep or high, hire a lighting installer and ask two questions: how do you attach the lights, and do you walk on the roof? A good answer is clips at the edge and no.
Match the attachment to the roof, and when in doubt ask the person who installed it.
| Roof type | Where lights can attach | What to avoid |
|---|---|---|
| Asphalt shingle | Clips on the gutter or fascia, or clips made for the shingle edge. | Nails, staples or hooks driven through shingles, and boots on the slope. See shingle cupping and curling for how edges lift. |
| Tile | Clips made for tile, or clips on the eave, gutter or fascia, from the ground or a ladder. | Walking on the tile. Tile can crack under foot. |
| Metal (standing seam or 5V crimp) | Ask the installer or manufacturer which clips they approve. | Drilling or screwing through panels. See metal roof screws leaking. |
| Low-slope or flat (TPO) | A wall or parapet, not the roof membrane. | Any hole through the membrane, and foot traffic where the surface is not meant for it. |
Coastline installs standing seam and 5V crimp metal roofs and works on shingle, tile and low-slope roofs. If you are not sure what your roof can take, send us a photo and say what you plan to do. The answer may be as simple as clipping to the fascia.
Look from the ground for anything that changed, and check the ceilings after the next rain.
Walk around the house with a phone camera or binoculars. NRCA recommends assessing a roof from ground level and leaving closer checks to a professional roofing contractor, which is good advice here too. Look for these things:
If you used nails or staples, or if anyone walked a tile roof, a roof inspection with a written photo report is a sensible way to catch a surprise leak early. See our roof inspection page and roof inspection cost in Florida. Our roof maintenance page covers what routine upkeep looks like.
"Josh was especially amazing. He was professional, patient, and took the time to explain everything clearly so I felt comfortable and informed throughout the entire process. You can tell he genuinely cares about his customers and takes pride in his work."Madison T.Roofing customer
"Good communication and did a great job."Rick R.Roofing customer, Florida Gulf Coast
"Highly recommend. Great communication. Great quality of work and very personable. Easy to work with. Will use again for home renovations."Justin S.Roofing customer, Florida Gulf Coast
We would not. IBHS says sunshine can drive roof temperatures over 200°F, tile can crack under foot, and OSHA's guidance for workers says not to stand on a roof steeper than 4 in 12 without fall protection. Clip lights to the edge from a ladder or the ground instead, or hire an installer who does not walk the roof.
Remove them by hand and look at the hole. A fastener hole in a shingle or tile is a path for water. Watch the ceilings under that spot after the next rain. If you want it checked, Coastline can inspect the roof and send a written photo report showing what was found.
The CPSC says never string together more than three sets of incandescent lights, and never overload outlets. For other kinds of lights, the label on the package gives the limit. Replace damaged strands before you hang them.
Yes, at the edge, with clips made for tile or for the eave or fascia, from the ground or a ladder. Do not walk on the tile. The Tile Roofing Institute says tile roofs should be installed by a certified professional roofing contractor, and tile cracks under foot.
Look from the ground for a lifted shingle edge, a cracked tile or a fastener left in the roof, then check ceilings after rain for stains. A stain days after the lights came down is worth a call. Our guide on ceiling water stains helps you tell roof leaks from plumbing.
Coastline will inspect it and send a written photo report with a straight answer on what, if anything, needs attention.
