Clay and concrete tiles are great roofing materials since they’re more durable than shingles, but they can break or crack if you apply too much pressure while you’re walking on them. Plus, on old roofs, you can run the risk of breaking a batten, which are the wooden beams the tiles are placed on. While it’s usually best to stay off your roof if possible, you can still walk on the tiles if you need to make repairs. Place your feet where the tiles overlap (usually the bottom third) and always walk on two tiles at a time, parallel to the ridge (peak) of the roof. We'll explain it even more in depth, below, and provide advice for safely getting up to your roof.

How to Safely Step on a Tile Roof

Place each foot on the bottom third of two tiles, perpendicular to the tile and parallel to the ridge (top) of the roof. If the tiles are domed, step on two of the peaks at once instead of on the valleys. Avoid walking on broken tiles and rain channels, which run vertically through the tiles.

  1. This helps you gain traction on the roof. [1] Wearing open-toed shoes, soles without grips and smooth fabrics can increase your chances of slipping.
  2. The bottoms of the tiles overlap with the tiles below them, so they’re better able to support your weight. The middle and tops of the tiles don’t have any supports underneath them, so they can break easily if you apply too much pressure. [2]
    • Don’t jump or move quickly between the tiles since you could break them if you step down too hard.
    • Leave about 1 centimetre (0.39 in) between your foot and the edge of the tile. While it’s supported by the tile beneath it, it’s more likely to chip off if your feet overlap it.

  3. This helps reduce the weight you put on each tile. [3] If your tiles are curved, put your toes on the peak of one tile and your heel on the peak of another.
    • Never put both feet on the same tile. It will apply too much pressure and likely cause it to break.
  4. Walk normally on the roof without lowering your center of gravity. Each time you step, apply pressure slowly to the foot you’re keeping on the roof. [4]
    • Walk diagonally up and down the roof to help keep your feet parallel to the ridge (peak of the roof) and to make it easier to step on two tiles at once.
    • If you’re afraid of falling off the roof, have vertigo, or have bad balance, you’re more likely to lower your center of gravity and break a tile. You can use one of your hands to steady yourself and “bear crawl” on the roof, but consider hiring someone else to do your work for you.
  5. Inspect the tiles that you want to step on to see if they have any cracks or damage. Avoid putting pressure where the tiles intersect side by side (the water channel) or where you notice damage. Stepping on broken tiles can also increase the chance that you’ll slip and fall. [5]
    • If a tile has been cut in any way (like where two planes of the roof meet) don’t walk on it. The cut makes the tile weaker.
  6. Only walk on the ridge, or peak, of the roof if it’s supported by concrete. If your ridge is reinforced, you’ll be able to see the mortar under the tiles. [6] Don’t walk on the hips (corners where two planes of the roof meet), because the tiles are often cut and more prone to cracking.
    • The tiles on the hips aren’t always secure, either, and you could risk slipping if one becomes unstuck. [7]

Walking on an Old Tile Roof

  1. The biggest risk of walking on a roof is sliding off. [8] Keeping your hands free helps you steady yourself on the roof. Wear rough pants, like jeans, to increase your traction.
    • If the pitch of the roof is very steep, avoid walking on it at all costs.
  2. When you’re on an old roof, you run the risk of breaking battens, or the beams that hold up the tiles. Check under your eaves to see how far apart the rafters are. When you walk on the roof, keep your feet as far apart as the rafters are spaced. [9]
    • This helps you make sure you’re always either on a rafter or straddling a rafter, which helps take pressure off the battens.
    • You can also check the rafters by looking at the ceiling of your attic.
    • Nowadays, rafters are usually spaced 24 inches (61 cm) apart, but spacing is more variable with old roofs.
  3. Step on the lower third of the tiles, perpendicular to the tiles and parallel to the peak of the roof. [10] By keeping your feet at least one row apart, you reduce the stress on any individual batten.
    • The bottom parts of the tiles are supported by the tiles beneath them, as well as the batten.
  4. If a tile is raised, that means there’s something under it. If you step on a raised tile, it will break as it shifts over the object holding it up. [11] If a tile is out of line with the other tiles in its row, that means that it’s loose and can slip out from under you.
    • Check for these tiles before walking across the roof.
  5. Keeping at least three points of contact on the roof spreads your weight out even further and reduces your chances of breaking a tile. [12] Keep your feet as far apart as the rafters are set, and place your hand in the middle.
  6. Don’t put one foot in front of the other. Instead, move your back foot slightly forward, then move your front foot slightly forward. [13] Bring your hand(s) forward as necessary.
  7. If you’re not sure where the rafters are, place one foot on the edge of the roof (but not the hip, where the tiles come to a peak) and the other one rafter space away. [14] Keep your feet sideways on the tile, and use both hands as you climb.
    • Go down the roof the same way.
  8. If you know how far apart the rafters are but aren't able to see them while you’re on the roof (or have a friend on the ground see them), start at one edge of the roof and walk over from there. You can measure the length between rafters with a tape measure. [15]
    • There will always be a rafter at the edges of the roof.
    • If the rafters are visible under the eaves, have a spotter on the ground to tell you where they are.

Getting on Your Roof Safely

  1. Tiles have a flat, smooth surface, so they don’t offer a lot of grip when you step on them. Once tiles get wet, they become even slicker and could cause you to slip and fall. If it rained recently or your roof is wet, wait 1-2 days for the tiles to dry before you stand on them. [16]
    • Never get on your roof while it’s wet since it increases the likelihood that you’ll fall.
  2. Use a ladder that extends 3 feet (0.91 m) taller than the edge of your roof. Place the base of the ladder on level ground, ¼ of its height away from your home. As you climb the ladder , maintain 3 points of contact at all times so you’re less likely to lose your balance or fall down. [17]
    • For example, if you have a 16 ft (4.9 m) ladder, you would place its base 4 feet (1.2 m) feet away from your home.
    • Ask a helper to hold the ladder in place while you climb it so it’s less likely to fall down.

    Warning: Avoid standing on the top 2 rungs of the ladder since you could easily lose your balance and cause it to fall.

  3. Put your legs through the loops on the safety harness and tighten them around your thighs. Put the top of the harness around your waist and tighten it so it’s secure. Tie a rope around a sturdy object on the roof, like a chimney, or a Ridge Pro hooked over the ridge of your roof. [18]
    • You can buy a safety harness online or from a home improvement store.
    • You can also make a harness with ropes .
    • While you don’t need a safety harness for a roof with a gentle slope, you can still wear one to reduce the risk of falling down.
    • If you don’t have a chimney or sturdy object on your roof, slide 2-3 tiles on your roof up so you can access the rafters underneath. Screw a harness anchor onto the rafters and tie the rope to it.

      Tips

      • Remove loose tiles from the roof. If a tile has come out of place and is just sitting on your roof, throw it off (when no one is beneath it) to let rain freely fall off of the roof. Having an obstruction can cause a leak, especially if the roof is in bad condition. [19]

      • Don’t walk on plywood. While it can distribute your weight, it’s very easy for plywood to slip off the roof, taking you with it.

      • Avoid stepping in the middle of a tile since it doesn’t have any support underneath it.
