Asphalt roofing

The life span of an asphalt-shingle roof is somewhere between 15 and 30 years, depending on the quality of the materials and the climate in your region. Wind can often cause as much damage as water, cold temperatures and sun. Manufacturers offer a wide range of products each with its own properties.

Sky's the limit when it comes to choice. There is something for everyone - all sorts of shapes, colours, levels of quality and price. The guarantee will generally depend on the quality. But even there you have lots of choice. Depending on the product and the manufacturer you can have a guarantee anywhere from 10 to 35 years. Generally, the heavier the shingle the longer it will last.

Choosing the right style

You really do need to bear in mind the type of architecture and the style of your house when you're choosing your roofing shingles. You'll also want your siding (brick, aluminum, vinyl, wood) to harmonize with the roof. You should expect a guarantee of 20 to 35 years, depending on the quality.

Three-tab shingle

The three-tab shingle is the most popular these days. It is very economical and has sort of become the standard. You can get it in any one of 15 colours and three different qualities.
For a country-style home the shake shingle looks every bit as effective as cedar shakes. The style is pretty well similar from one manufacturer to the next. This is a high-quality product designed to give years of elegance.

Victorian shingles

These shingles are really coming back into style, particularly with the new rage for Victorian houses everywhere. The tongues of these shingles are rounded and the large dark patch gives a feeling of relief and creates an interesting effect in the sun.
The shape and irregular texture of these shingles make them look like real slate. What's more, they come in just about the same colours as natural slate: grey, blue, black, taupe, etc.

Interlocking shingle

These shingles act like a suit of armour on your roof because they are specially designed to resist high winds. Each piece locks into the next creating an interesting geometric effect.

Architectural-style shingles

These shingles feature shading and vertical lines drawn on them to give a sense of relief and volume to the roof. The effect is modern and original.

Shingles for slow-pitched roofs

Once they are down, shingles for slow-pitched roofs look just like the standard three-tab shingle. But they have a wider section covering the adjacent shingle and the technique used to lay them is a bit different. They are suitable for roofs with a pitch less than 4" to the foot and up to 2" to the foot.

Reroofing with asphalt shingles

If your house was built in the 70's or in the beginning of the 80's, it's probably time to change your shingles. A few simple and obvious signs may lead you to come to an informed decision. Below, you will find a description of the principal symptoms that appear in a worn-out roof. Before beginning to repair the roof, we advise you to properly plan the job. You will need to remove the old shingles and dispose of them properly. Consult your local municipality to obtain the required permits. Try to have the help of at least three other people, as working on the house roof is never easy.

Broken shingles

When shingles are broken, they no longer protect the house from water infiltration, particularly on low-pitched roofs, where water drains more slowly.

Wavy shingles

A problem originating from warping of the roof support structure, which is often caused by poor attic ventilation.

Warped shingles

Natural aging produces this deformation. Once more, the warped sections are very vulnerable to wind, hail and ice.

Raised shingles

When the shingle edges become raised, they become vulnerable to wind. This problem is common to old roofs.
