Roofing in St. John's, layer by layer

A roof is a stack.

The Black Label mark is a stack of chevrons, and a shingle roof is built the same way. Here is the general order, from the top down.

1. 1ShinglesThe surface you see from the street. It sheds rain and snow and takes the wind and sun.
2. 2UnderlaymentA membrane laid over the deck, beneath the shingles. If water gets past the surface, this is the next line of defence.
3. 3Roof deckThe plywood or OSB sheathing the roof is fastened to. Everything above it depends on the deck being sound.

That is a general guide to a shingle roof, not a description of any one job. Black Label’s project album on Facebook shows shingle roofs and underlayment going on, and new framing under a gambrel roof.

Have these ready when you call.

• Your street or neighbourhood in St. John's or the surrounding area.
• Where you see a problem, such as a leak, a stain or missing shingles.
• A few photos of the roof, if you can take them safely from the ground.
• When you would like the work done.
