Traditional shingles have three tabs or three parts to it, each approximately a foot long. If you look at them from the ground they look like they have lines in them. These lines are actually ‘cut outs’ of the shingle to give it’s unique look.

Nowadays the majority of homes are using what some call ‘designer shingles’. Very pretty and in a variety of colours. All shingle manufacturers seem to have their own line of designer shingles.

Recently I’ve had to do some ‘needle in a haystack’ (no obvious signs of roof leak source) repairs that were on a designer shingle roof.

There was nothing wrong with the roofing shingles. There was everything wrong with the shingle installer’s placement of nails on or in the shingle.

The proper placement of nails on a shingle is written on the shingle wrapper. Some ‘roofers’ in our neck of the woods choose not to read them.

There’s even a line on the shingle showing you where to nail.

Shingles are staggered. One shingle butts up against another. Water can run between where the shingles butt up to each other. You DON’T put a nail where the water is going to run…period.

You can research this easy enough. After you do that, perhaps give your roofer a little test on it BEFORE he installs your new roof. If he fails the test and despite the good price he may have given you, reconsider.

Some say Roofing is an unregulated trade. There’s no roofing school for shinglers. Buyer beware. If they don’t know where to put a nail in a shingle I doubt if they’ll come back to fix all their roof leaks…in fact they don’t.

I know the first thing I would do to test a roofer’s expertise nowadays is…throw a shingle down on the ground and say ‘Show me where you would put your nails in that shingle ‘. If he failed that simple fundamental…he’s out the door!

Nails in the right place DON’T cause leaks. Nails in the right place keep shingles from blowing off.
