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.
- Metal flashing
- Roofing nails
- Roofing hammer
- Roofing tar
- Chalk line
- Mineral roofing felt
- Tin snips
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.
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.
