Owens Corning Shingles 2011 – Our Review in General

Owens Corning Shingles, by default, are a substantial and predictable manufacturer of shingles – Owens Corning is obviously a substantial company. However, in Canada, at least in Western Canada, Owens Corning hasn’t been represented until now, in a way that say IKO or BP shingles have. IKO has significant distribution roots in Western Canada being they are originally from the Calgary, AB area – so our confidence in a predictable representation in the IKO shingle is “very high”, and BP Shingles have been well represented through stores like Home Depot and traditional roofing suppliers for some time in Western Canada.

Owens Corning Shingles now have significant representation in Western Canada as of 2011, in that Lowes has them stocked on its shelves. Lowes stores have popped up all over Western Canada. This increases our comfort level with shingle style and colour availability, and warranty/service support locally in Western Canada.

Owens Corning Shingles have always performed well and are a predictable shingle product. In the same way that we would review the performance, quality, and choice of shingles in our IKO Shingle Reviews on this blog…. we encourage homeowners with specialized or specific requirements from their shingles to look at alternatives in the market also. The Owens lineup is wide and represents designer, luxury and algae resistant requirements, but specific to those and other particular needs we always encourage homeowners to look at alternatives to be sure the right choice of shingle is made. For example, if you are re-roofing a shake roof (be it cedar shake or a pine shake roof) and you are looking for a really nice looking shake shingle that is specific to your “preference” to replace your shake roof, then you want to look at the alternative shingles available in the higher price range to be sure your preference is met – luxury or specialty shingles, especially the true shake looking shingles with the right profiles, are a significant expense.

In summary, Owens Corning Shingles are a solid choice for homeowners that require a modest, mid, or mid-high shingle for their home. The higher end more costly shingles meet more scrutiny in the marketplace and choice of shingle becomes more specific to personal preference. Malarkey, GAF, etc. have high end offerings that should be considered as well. And now that stores like Lowes are carrying the Owens Corning Shingles in Western Canada, the representation, supply, types, and colors of shingles readily available will be predictable for homeowners.

Our Review of Owens Corning Berkshire Shingles

The Berkshire Shingle line are a high end shingle product; classic, elegant and showing great street appeal. This would be a competitive shingle offering to IKO’s Royal Estate Shingle that became available in 2011. Colour choice with shingles is limited, which is common at this level of quality. I believe there are five colours currently available. Owens Corning has a 10 Year “Tru Protection” period on their shingles (which would be similar to the 15 Year no grief protection IKO Shingles carry), and the Berkshire shingle has a Limited Lifetime Warranty coverage.

Our Review of Owens Corning Woodmoor Shingle 

The Owens Corning Woodmoor Shingle Collection is for the shake to asphalt conversion market. The Woodmoor Shingle would be a similar shingle offering to the IKO Armourshake, the Certainteed Presidential TL, and others from shingle manufacturers like GAF and Malarkey.

Many of our clients in Alberta, in areas like Calgary and Edmonton, have a real shingle re-roof dilemma if they are re-roofing a Pine Shake roof. Short story is that not all Pine Shake roofs in Alberta performed as represented. The challenge these homeowners face is replacing a Pine Shake roof that has a thick profile and texture and getting that same look in an asphalt shingle. When they price out Cedar Shake costs or Pine Shake Costs quite often they look to this category of Shake Look-Alike Shingles. Then the price of the high profile shake looking shingles can become price prohibitive. We encourage homeowners in this category of shingle shopping to consider all options.

In high wind areas such as the open prairies it is also nice to consider a heavier shingle like the Shake Looking Shingles, and in areas like North Vancouver, Squamish, Whistler our clients consider the Shake Shingle Look of the Owens Corning Woodmoor and similar shingle offerings to be appropriate to the surroundings and provide excellent street appeal. We have even convinced areas with Architectural Controls for the roofing material being used to re-consider some of the shingle offerings that show a great shake look. Whistler for example has a Shake consideration in the Architectural Controls as does Fairmont, BC where we recently completed a Shake to Shake Looking Shingle Conversion in one of these areas.

Our Review of the Owens Corning WeatherGuard Shingle

The Owens Corning WeatherGuard Shingle is a true high performance shingle. Impact resistant (our clients in southern and central Alberta get a hail beating every year), HIGH WIND RATING IS 130 MPH, and we have many homeowners that constantly struggle with high wind areas and blow offs, etc. Coming home after a vacation to find your shingles blown off and a major leak and moisture in your home really is not fun. The Owens Corning WeatherGuard Shingle is one of the best in its class – hand down. This shingle is available in lots of colours, has great texture, it’s a good looking shingle, and it has a moderate price point.

Our Review of the Owens Corning Duration Shingles

The Duration Shingles from Owens Corning would be a similar offering to the IKO Cambridge Shingles, BP Harmony Shingles, etc. It is the standard laminate shingle offering in the mid range that most homeowners purchase. The price of the Owens Corning Duration shingles is competitive, the performance is competitive, and the shingle profile and texture Owens Corning Duration is a good looking laminate shingle. A great shingle product for the average homeowner in Western Canada.

Owens Corning Shingles – Oakridge Shingles

The Oakridge line of Owens Corning Shingles is a laminate similar to the Duration Shingles above but the entry step up from the 3 Tab Shingle offerings below.

Owens Corning Supreme Shingles

The Supreme Shingle offering from Owens Corning is the traditional 3 tab shingle. There are many colors available and they are inexpensive. The perform as well as any other offering on the market for 3 Tab shingles. Our only word of advice as it applies to a 3 Tab Shingle, be sure to know what you are doing before you start shingling. Learning how to shingle a 3 Tab shingle is different than the Laminate Shingle offerings above.

First Annual GRS Shingle Sale – Beat the Cost of Rising  Prices with GRS’s Shingle Dutch Auction Sale!

General Roofing Systems Canada (GRS) will be holding its First Annual Shingle Dutch Auction Sale starting November 1, 2011. Save Up to 20%. The sale will not end until all roof replacements are sold out!

Along with the rising prices in our supermarkets and gas pumps, we now can see them in our shingles and roofing materials.  2011 brought a number of price increases from our suppliers and we were shocked to see how drastically they increased.

The staff at GRS decided that it is unfair to our customers to make them pay for new market increases, so we have developed a way to assist our customers who are looking for reasonably priced roof replacements. With doing this it not only benefits the customers, but our roofers as well by keeping them busy during slow periods.

Conditions for the Roof Shingle Dutch Auction Sale:

  1. Start Date: The First Annual GRS Dutch Auction Shingle Sale will be posted on November 1st, 2011.
  2. Sale Limitations: this sale will only have 100 shingle roof replacements available
  3. Shingle Sale Countdown: On November 1, 2011 GRS will post the 100 Shingle Replacements that are available and as the replacement orders are received, the counter showing the amount left  will go down until no shingle roof replacements are left. This is sale that you do not want to miss and should plan accordingly. If you wait too long to place your order, you face the possibility of it not being processed due to not having enough time to meet the sale deadline.
  4. Shingle Sale Discounts: the “Dutch Auction” Sale Component. Starting November 1, 2011 the shingle roof replacement discount will begin at 1%, as the days go by, the discount will increase. So by November 19th, you would receive a 19% discount. This sale will continue from the 1st to the 20th or until the shingles are all sold. Which ever event occurs first.
  5. Shingle Sale Estimates: All  sales will be calculated and completed by the way of satellite imaging.  Measurements will be taken by our shingle estimating staff  which will count the initial shingle volume and provide the cost estimate. After a shingles order is received, satellite measurements will be taken of your home, the shingle requirements  will be estimated and the cost established per discount for that day, and your order will then be placed. At some point between your order and your shingle installation date, a roof assessment and inspection will be completed of your roof by one of our  experts. This is to ensure all the measurements taken via satellite are accurate and standard inspection practices were followed. This helps us to ensure our customers achieve 100 % satisfaction with our work. If the measurement on site concludes that more or less shingles are required, your estimate will be adjusted accordingly at the sale price.
  6. Shingle Sale Material Choices – Volume Shingle Purchasing: To be sure we are able to supply 100 homes with shingles in such a short period, while still being able to cut the cost via mass volume purchasing, GRS will only be offering two specific models for  each variation. For the laminate version we are offering a  asphalt type while the other is a SBS modified laminate shingle. There will also be two 3 Tab shingle types – one asphalt and one SBS modified 3 tab shingle. The shingle options will be posted to this blog prior to the sale commencing. All shingle installations will follow our premium, high-end installation specifications which can be found at the following link: https://www.grscanadainc.com/Roof_Replacement_Home_Guide.html.
  7. Shingle Sale Installation Dates: All shingles sold under this cost reduction program must be installed by GRS between the dates of Jan 2, 2012 and Mar 30, 2012. Our primary installation season is from May to December each year,  with installing the cost reduced shingles from Jan 2, 2012 to Mar 30, 2012 will keep our  installers busy through the slower time of the year. The shingles will have to be installed on warmer days and are required to follow the guidelines of the permissible temperatures of installation by the manufacturer. If we do not get enough nice days prior to Mar 30, 2012, we will continue installing into April of 2012 to complete the orders.
  8. Shingle Sale Terms of Payment: All shingle roof replacements must be paid in full upon completion of the  installation, There are no deposits required.  A credit card, letter of intent or a post dated cheque will be requested in order to secure the shingle sale order. NO DEPOSITS will be taken from your credit card, as no deposits are required. All cancellations for orders will be honoured at any point up until the point of  installation or the shingles being loaded to the roof of your home. The intent of the  sale is to keep our shingle installers busy during the slower time of the year and to give our customers an opportunity for cost savings on shingles. After the roof is installed,  payments are due in full.
  9. Shingle Sale – Keeping Shingle Prices in Perspective: General Roofing Systems Canada have unusually high specifications that are standard for our roof replacements. Our everyday pricing for shingles will typically cost between 3% – 15% more than our typical competitor. This is due to the cost of material required to perform  shingle roof replacements to our complete specifications.

We are only mentioning this fact to you in order to provide proper clarity and understanding with our materials and Prices. Your quotation that you receive with GRS during this sale, may also be found with another company.

There is no magic way to reduce the price of a shingle installation. A high quality shingle re roof simply costs more.
