When choosing the type of roofing for you home or business, two factors to consider are the longevity of roof materials and pricing. Here are some of the different materials available and their life expectancy and how cost may affect your choice:
ASPHALT SHINGLES
Asphalt shingles have been around a long time and typically last 20 years, however high quality asphalt shingles are now warrantied for up to 50 years, expect to pay a premium for long life products.
ARCHITECTURAL SHINGLES
Architectural shingles last about 30 years on average.
WOOD SHAKES AND SHINGLES
Depending on the climate last about 30 years but could last longer in moderate climate conditions. With Vancouver’s heavy rain 30 years is a good benchmark.
METAL ROOFING
The International Association of Certified Home Inspectors project metal roofing to last between 40 and 80 years. The Metal Roof Alliance give a life expectancy of at least 40 to 60 years.
SLATE, CONCRETE AND CLAY TILES
Each of these products is rated for a life expectancy of 100 years or more although do not expect a maintenance free roof. Tiles occasional crack and will need periodic cleaning.
PROS & CONS OF EACH PRODUCTS
Asphalt is the most widely used and is relatively inexpensive and available in a wide variety of colors and patterns.
Shingles that are architectural are relatively new and have the look of wood shakes or slate tiles and are much less expensive than the natural products they imitate. Their chief drawback is a shorter life.
Metal roofs weigh about half as much as asphalt shingles and the problems they present are the same as most other other products, leaks, punctures, tears or pooling of water. Metal roofs are much more expensive than asphalt shingles.
Wood shakes or shingles tend to warp and curl from the constant wetting and drying process they experience. In Vancouver’s climate wood shake roofs will need more maintenance than the other products. Cedar shakes are also quite expensive compared to Asphalt.
The main drawback to a slate roof is its weight. Slate and tile roofs require a much more substantial roof deck to support the weight. A heavy roof is much more prone to damage your home in earthquakes.
INCREASING THE LONGEVITY OF YOUR ROOF
- Keep your roof clean by performing a once yearly inspection of your roof or consider hiring someone to do it for you.
- Carefully climb onto your roof and clear any debris, leaves and tree branches that may have been deposited there during seasonal storms.
- Although many products today contain moss inhibitors, you will still find moss or algae build up and you should take measures to carefully remove it.
- Trim any overhanging branches as they can crash against the roof and cause major damage to your roof during storms.
- Lastly, check your gutters to ensure they’re clear and directing water away from your roof.
