Lay roofing shingles made of bitumen

Roof shingles are usually found in Germany on smaller buildings that are not intended for living. Laying roofing tiles made of bitumen is a demanding activity for the experienced do-it-yourself enthusiast. Therefore, we have provided you with detailed instructions on how to lay roofing shingles made of bitumen.

Bitumen shingles are mainly found on the following building types.

  • garden shed
  • toolshed
  • terrace roofs
  • entrance canopies

Before buying the bitumen roof shingles

Even before you buy the roof shingles, make sure that the bitumen shingles are suitable for the roof pitch angle of your roof to be covered. The shingles are classified according to different angles of inclination and concomitantly in their shape.

  • Roof shingles for an inclination angle equal to or greater than 15 degrees
  • Roof shingles for an inclination angle equal to or greater than 20 degrees
  • Roof shingles for an inclination angle equal to or greater than 25 degrees

In addition, you can also choose the shingles made of bitumen by color. In addition, you need bitumen membranes, for example V13, for undercoverage for an optimally prepared substrate. These bitumen membranes act as a vapor barrier to the wooden substrate and ensure good ventilation of the roof shingles.

Step-by-step instructions for laying bitumen shingles

  • Bituminous membranes, 100 cm wide
  • Roof shingles made of bitumen
  • bitumen adhesive
  • End plates for fireplace and wall finish
  • Roofing pens, galvanized
  • possibly eaves moldings for verge and eaves
  • hammer
  • Stanley knife with hook blade
  • Iron or metal profile for cutting the shingles
  • Meterstab
  • Easel or site manager

1. Preparatory work

The surface, usually a wooden roof or formwork, must be completely clean and dry. If you use eaves moldings, attach them to the eaves now.

Start with the lowest bituminous membrane. Allow the strips to protrude about 10 cm at the verge and at the eaves. Lay the next track with a longitudinal overlap of 50 cm. Use as few nails as possible to fasten the bituminous sheets. The last bituminous membrane should be folded symmetrically over the gable.

2. Laying roofing shingles made of bitumen

The first row of shingles

Cut the first row of shingles lengthwise at the level of the cut ends of the individual shingle tabs. Now nail the shingles with an overhang on the verge and eaves of about 8 to 10 mm. The nails should be positioned about 2.5 cm to the left and right and 2.5 cm above the incision ends.

The second row of shingles

From the second row of shingles, cut the tongues halfway down the length of the tongue. At the same time remove a complete half shingle tongue across. Lay the shingle so that the half-cut tongues end exactly at the incision ends of the first shingles.

From the third row of shingles

From the third row of shingles you do not have to cut any more shingles lengthwise. However, now remove half a shingle tongue more, so a total of a complete tongue. With each new row of shingles, you always remove half a shingle, that is now a shingle, then 1½, then 2, and so on. Lay the shingles down to below the gable.

3. Lay the gable with shingles made of bitumen

It is often advised to use the same shingles for the gable as for the roof. However, this is only true for rectangular shingles. If you have laid beaver or triangular shingles, also use rectangular bitumen shingles for the ridge series.

To do this, cut off all the shingles at the incisions. Then cut the part behind the tongue in a trapezoidal shape and tapering outwards to the left and right. The tip of the Schindelzunge shows left and right on the verge outward. Now work from the inside out. For the last shingle use only the gable tongue cut to the rectangle.

4. Lay roofs with bitumen shingles

In roof gutters, let the shingles overlap alternately from right and left by about 30 cm. In the upwardly facing corner of the overlapped shingles, insert a roofing felt pin for attachment.

5. Fireplace and wall finish

On wall closures and chimneys you use the end plates. These are glued to the bitumen, then the roof clapboard is glued to it. Proceed with each individual row of shingles along the corresponding ends.

Tips & Tricks

Depending on how flat or steep the roof pitch angle is, you can attach the shingles made of bitumen with different numbers of nails. On the packaging of the manufacturer, there is information on which positions you hit the Dachpappstifte exactly.

Always hit the roofing felt with emotion. Under no circumstances may you sink the pin head in the bitumen shingle.
