Types of Roofing

Asphalt shingles ($)

Asphalt shingles will last for about 15–30 years. They are, far and away, the most popular roofing material because of their cost effectiveness.

When it comes to durability, though, be careful. Never choose the cheapest asphalt shingles, even if cost is a major issue for you. Look for shingles that have a decent hail rating, a good indicator of impact resistance and overall durability.

Roofing material manufacturers are not legally required to report their hail rating, so if you don’t see one, this isn’t a good sign. Hail rating is particularly important with asphalt shingles. Because they’re so common, their quality ranges wildly.

Unfortunately, asphalt is a petroleum-based material. This means that it’s not the most sustainable roofing material option available. Fortunately, asphalt shingles are recyclable—just find a local shingle recycling center and they’ll ensure that your asphalt shingles don’t end up in a landfill.

Wooden shingles and shakes ($$)

This roofing material should last between 30 and 50 years. Wood shingles are typically made of fire-resistant woods such as cedar or redwood.

While they last longer than asphalt shingles, they are not as durable. Although they are fire resistant (and can be sprayed with fire retardant), they are not fireproof. Wood shingles and shakes are also prone to cracking, so keep your eye out for a manufacturer with a good hail rating.

When it comes to energy efficiency, wood is a natural insulator—wood shingles are naturally about two times as efficient as asphalt shingles. And because they’re 100% natural, asphalt shingles are one of the most sustainable roofing materials on the market.

Metal ($$)

Metal roofing materials will last about 30–50 years. Made of steel, copper, zinc alloy, or aluminum, metal roofs are slightly more expensive than their asphalt and wood counterparts. That said, they are significantly more durable.

Metal roofs are impact resistant and will serve you well in inclement weather (plus, the sound of rain on a metal roof is wonderful). Also, they need a lot less maintenance than most roofing materials. They are very energy efficient—while asphalt shingles tend to hover around the outside temperature (whether high or low), metal roofs act as a natural insulator. This keeps your home cooler during warm weather and warmer during cold weather.

Finally, their recyclability is unparalleled. Not only are most metal roofs created from recycled materials, many are also 100% recyclable themselves.

Plastic Polymer ($$$)

Plastic polymer roofs will last for 50+ years and are an incredibly durable roofing material. Polymer roofing shingles are created to look like slate or wood shingles, but they require significantly less maintenance.

Plastic polymer roofs have high hail ratings and they’ll hold up well in inclement weather. Unfortunately, they’re so durable because plastics are built to last, which makes them uniquely unsustainable.

If you decide to use plastic polymer, look for manufacturers that use recycled materials. That said, they are very energy efficient. Plastic roofs, like metal roofs, reflect energy rather than absorb it. This will keep your home cooler during the summer and warmer in the winter.

Slate ($$$$)

A roof made from slate can last as long as 75–150 years. One of the oldest roofing materials, slate is also one of the most expensive.

When it comes to durability, slate stands out from the competition. It’s both fireproof and virtually invincible in most inclement weather. Note that installation should be carefully executed—slate tiles can crack under the weight of the average person.

Slate is one of the most expensive materials because it will last for the better part of a century, and if the roof is properly constructed, more than 150 years. Because of this, slate is an incredibly sustainable roofing material.

Roofing waste (specifically asphalt shingle waste) accounts for 3% of all waste in landfills. This is because homeowners have to replace most roofing materials every 30–50 years. A roof that could last three times as long as its competition is much better for the environment.

And slate is a naturally occurring material, which means that the manufacturing process doesn’t introduce toxins. Finally, because slate is one of the densest roofing materials on the market, it’s incredibly energy efficient, helping to regulate your home’s internal temperature.


Cellulose Insulation – the Greener Choice

Is cellulose insulation new?

Cellulose has been around for 60+ years. With increased awareness about being environmentally responsible and reducing energy costs and the ease with which it can be installed in hard-to-reach areas, homeowners, architects, engineers and builders have discovered that cellulose is a superior approach to traditional glass or mineral fiber insulation.



Which Kind of Insulation Is Best?

Insulation is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value of thermal insulation depends on the type of material, its thickness, and its density. In calculating the R-value of a multi-layered installation, the R-values of the individual layers are added.



Roofing Repairs

Fluctuating temperatures, animal damage, ice dams and premature roof failure can be serious and cause damage to your insulation and home,. A yearly inspection of your roof is recommended More…

Why Insulate a Garage?

Even though garages are typically the largest un-insulated room in the house, garage door insulation is often overlooked. Insulating your garage door is a very wise answer to rising costs in heating and utility bills.



Attic Insulation what to know?

It is important to consider insulating your attic however there are important things to consider such as:

Cellulose vs. Fibreglass.

Cellulose is the insulation of choice.  Fibreglass is good, too, but it has a lower insulative value. Cellulose is made from recycled materials, is fire resistant  class-1 fire rating thanks to its treatment houses that catch fire burn slower with cellulose installed than with fiberglass. Cellulose provides better sound insulation than fiberglass – homes are less noisy with cellulose.

Fibreglass is a suspected carcinogen and carries a hazard warning label. Cellulose is much near benign. Many fiberglass installers “fluff” the fiber with extra air, so you don’t get as much insulation as you’re supposed to. This trickery can’t easily be done with cellulose, and certainly not to the extent that as with fibreglass. Fibreglass settles much more than cellulose, like a box of cereal. So over time you actually get fewer inches of fiberglass than you paid for resulting in more heat loss to your attic.

Attic Ventilation.

Ventilation might seem like a minor consideration, but when done properly, it can extend the life of your attic, insulation, roof structure and shingles saving you hundreds of dollars in repair costs.

In the summer, hot, moist air in the attic can effect roof sheathing and cause shingles to deteriorate. A hot attic also makes a home more difficult to cool, results to over worked air cooling and in added energy costs.

In the winter, heat loss in an attic melts snow and can form ice dams at the roof edge. Water can back up under your shingles, wetting, damaging, insulation and eventually the structure of the roof itself. Ice dams can even cause leaks inside your home, resulting in drywall damage. Mould also flourishes in humid attics.

Drafts & Air Leakage

Ensure exhaust venting is insulated, pot lights are protected, electrical wires & fixtures are sealed to prevent drafts and heat loss to attic. It will also help prevent the establishing of mould growth caused by moisture.

Attic insulation with proper ventilation and sealing drafts etc. provides you more comfort and will save 30-40% in energy bills.
