Installing shingles on a valley roof

To make a roof valley waterproof you will need to pay great attention. The roof valley is where all the water and snow will gather and this area should be very durable and well covered. Paying special attention to this part of your roof will ensure that you will not have any problems with water.

Here are the tools and materials needed:

  • Metal flashing
  • Shingles
  • Roofing nails
  • Roofing hammer
  • Roofing tar
  • Chalk line
  • Mineral roofing felt
  • Tin snips
  • Roller

Metal flashing

Before installing the shingles, you will need to install a metal flashing for better protection. It has to be at least 18 inches wide. It is best if the flashing is made from aluminum to allow bending and easier installation. Secure it with roofing nails. To waterproof it, use roofing tar along the edges.

Mineral roofing felt

Now roll out the roofing material and make it 18 inches wide, from the center of the valley. Roll it down and then secure it with roofing nails.

Shingle lines

Lay a shingle on the valley without fixing it and see how the rest of them should be installed. You can draw a line for reference.

Installing the shingles

Now begin laying the shingles, from the top of the valley. Cut the tabs off of one shingle and then lay it with a 1/4 inch overhang the bottom edge. Make sure that the shingle is flat along the surface and then nail it in place. Continue moving up with the shingles. Overlap each of the shingles, at least 4-5 inches.
