Re-Roofing Roof Shingles The Right Way

General Roofing Systems Canada Offers Expert Re-Roofing with our Exclusive GRS Re-Roofing Specifications in Toronto, Calgary, Red Deer, Edmonton, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Kelowna, Vancouver, Whistler, and points between.

GRS Canada has an unusual residential re-roofing specification standard – interestingly enough… it works!

Ask us for re-roofing client references that will tell you all about how our systems keep their homes completely, perfectly water tight without any concern.

Re-Roofing With Premium 44" Ice and Water Underlay to Roof Eave and Wall
Re-Roofing With Premium 44″ Ice and
Water Underlay to Roof Eave and Wall

In the photo above, a premium 44 in. Ice & Water membrane (IKO Goldshield Ice and Water Protector) is applied at the roof edge (eave) and to the wall area to the deck and up & under the step flashing onto the wall. The roof eave protection avoids backup from water and ice at the eaves-trough during freeze, thaw, and ice damming. The ice and water membrane is a peel and stick self-adhered membrane that sticks to the roof deck, blocking ice and water penetration, thus mitigating roof rot. The Ice & Water under the step flashing at the wall and up the wall also protects the deck, wall, and vapour barrier from ice and water penetration.

Also of note in the photo is the high gauge coloured metal eave drip edge flashing (GRS re-roofing standard), the wall area step flashing (galvanized metal that meets the wall) will be coloured when the re-roofing process is complete as the profile of the previous pine shakes were higher than the new laminate shingles, and finally of note in this photo is the ultra premium synthetic underlayment  (Titanium Synthetic Underlayment) to the rest of the roof deck (also a GRS standard re-roofing specification).

Titanium synthetic roof underlayment is many times lighter and twenty times stronger than standard roof felt. It doesn’t break down like felt in UV, doesn’t expand/contract or get brittle like roofing felt, contributes to LEED points, and is 100% recyclable.

The photo to the right shows an Ice & Water membrane to the back side of the gooseneck roof vent and to the top side areas, and again this membrane is along the wall and step flashing of the roof (GRS standard).

and Side of Roof Openings

Under that gooseneck vent is a premium Karnak caulking bead for added protection.

Have Ice & Water “necktie” all roof openings avoids ice/water backup under the shingles at the back of the vent area and under the vent onto the roof deck and into your attic and home. That is the number one repair our technicians undertake when repairing shingles roofs – likely 8 out of every 10 emergency roof repair calls we receive in sloped shingle roofing is for this reason (or some form of underlayment deficiency).

The photo to the right shows another GRS specification. A premium 44 in. Ice & Water membrane is applied to the roof sheathing in the valley, then a high

Re-Roofing Master Spec - Ice and Water is applied to the roof deck, then high guage valley metal (coloured) and the premium ice and water membrane to edges of valley metal to ensure "monolithic" type seal.

metal to ensure “monolithic” type seal.

gauge coloured metal is applied over the membrane. For extra confidence, a “monolithic” type roof seal is created using another Ice & Water application to the edges of the valley metal. The premium synthetic roof underlayment is then run into the valley area.

If the metal has a crimp at any point, and when the metal expands and extracts (which metal does), it happens to snap – this is where a lot of roof leaks occur. When this occurs, we do not have to worry about this as our metal is a heavier than normal gauge and should not snap, but we also have a premium quality membrane underneath the metal valley.

Also, if ice and water backs up in our valleys and gets under the shingles, which regularly occurs, we have yet more sealant again at the edges of the valleys, which seals the roof valley. In this way, it cannot leak, as water cannot get around the side of the valley metal to the roof deck.

Finally, even when we close the roofing valley with shingles, we still use this underlayment re-roof specification so that when the roof shingles fail in the valley from age or when someone walks on the shingles in the valley, we then have the Ice & Water and metal underneath the shingles. We apply this method when some homeowners want a re-roof to show only shingles and no valley metal in the roof valley. Our specification mitigates shingle deterioration in the roof valley area first, as that is where most roof water runs and ice builds up.

Solar Roof Shingles

Dow Announces First Markets in USA to have Powerhouse Shingles Installed

In Canada, we’ve been waiting for the DOW POWERHOUSE Solar Shingles to become available.

An article in the Denver Business Journal this week announced the availability of solar shingles by DOW to be first launched in Colorado. The Denver Business Journal lists three local roofing companies that have been selected to be the first installers of the Powerhouse Solar Shingles.

Article Link: Denver Business Journal Dow Solar Shingle Article

Earlier this year, the Hall family in the US received the solar shingle installation. Follow-up articles on both the internet and in print state that the family is pleased with the shingles.

The Dow Solar Shingle website page has updates and articles that keep homeowners up to date with the shingle roll out. As DOW is making the new solar technology available in various markets, solar shingle availability areas will be posted at this page.

The Asbestos Debate Heats up on the News and in the Roofing Crew Trucks

Anthophyllite asbestos,  Scanning electron microscope pic
Anthophyllite asbestos,
Scanning electron microscope pic

 When it comes to the safety aspect of the roofing occupation, the truth remains obvious.  Roofing is a dangerous. However most roofers don’t stop and discuss it on a regular basis . In fact I often wonder if some of my co-workers are in denial (I think to myself regularly when on the roof, “the stats don’t lie – roofing is most definitely dangerous”).

Just a few weeks back, a co-roofer friend of mine was re-roofing a home (not co-worker as he works elsewhere), he came screaming off a residential two story home and ended up shattering his feet. He was incredibly Lucky that he only sustained those injuries it was not some thing much more serious. With accidents like that you learn to appreciate having to endure broken bones rather than having some one tell your wife and kids that dad won’t be coming home.

When the recent asbestos stories started hitting the news, what I found interesting as a roofer is that the roofers began actually talking about safety in the workplace. The recent public asbestos debates have increased conversations with the roofers around me, and when contractors and “suits” visit I’ve noticed the management, architects, engineers and the like discussing the same issue.

What is peaking the interest of the roofers and management alike is the obvious very present potential danger of asbestos in the roofing material itself…

Common questions and comments around the water cooler (so to speak) go like this;

“We rip these roofs off every day, is there asbestos in the  materials we’re ripping off these buildings?”


“Asbestos in roofing materials?” 


“Are there risks to the roofers?” 


“What about home-owners and business owners, what are the risks to people inside

In consideration to GRS starting the 2012 roofing season with a complete over-haul/ revamping of the safe work practices. We thought it would be best to include information regarding the current debate of asbestos into the safe work place packages.

All GRS safety packages will include articles from this blog, written by other team members about our crews personal journey and experiences towards our effort to make GRS and roofing in general, a safer work environment.

The contributions from the GRS staff will include articles aimed towards safe-work practices in roofing, the equipment we use, and the safety training and certifications roofers can acquire. The GRS staff will also be trying on, testing, and reviewing a number of new safety equipment brands and types of equipment in an effort to broaden our crew equipping horizons. All of which we will share on our blog.

We will keep this article short. But before we go, and prior to follow-up articles, we thought it would be best to provide some background for folks to consider. Listed below are some interesting links to information we found on the internet as it relates to understanding asbestos, asbestos in roofing, what period of time asbestos has been used, what forms of asbestos are considered dangerous, and simple definitions.

Product Review: Malarkey Shingles

Malarkey Shingles are one of the top rated shingles on the market and tend to be a favorite for our roof installers for projects requiring replacements/ re-roofing. The malarkey shingle line up is considered to be one of the “best bought” as they are the most predictable shingles available for the 2011 roofing season.

Roof Conversions – Shake Roof Replacement

Shake roof replacement / re roofing decisions can be more complicated than shingle to shingle re roof decisions. For shake to shingle conversions of either Cedar shakes or Pine Shakes, the Malarkey Legacy shingle is one of the many options available. Although they are not as thick and they do not have the same shingle texture and profile that other shake to shingle replacement options offer, Such as Shingles from companies like Certainteed, IKO, and GAF.  The Malarkey Legacy shingle is an excellent SBS laminate shingle that demonstrates well in its category of shingle.

Malarkey Shingles

Malarkey XL Review

The Malarkey Northwest XL Shingle is a respectable Asphalt Laminate Shingle. It is a 3M Scotchgard Algae Resistant Shingle. LOW SLOPE ROOFING – The Northwest specifications state that it can be installed onto slopes as low as 2:12 if you follow Malarkey underlay specifications for low slope roofing (pending upon your local building codes). The Malarkey Northwest is also a heavy shingle – a 4  bundle shingle that has a high tensile strength. Also, the Malarkey Northwest has the “Zone” technology that really assists with the application as the nailing zone is much larger than other conventional shingles. All in all, GRS installers recommend the Northwest Malarkey shingle when a strong, asphalt, laminate shingle is wanted.

 

Malarkey Legacy Review

Our overall review of the Malarkey SBS Rubber-Modified Asphalt Laminate Shingle states that it is often preferred by our installers. The SBS Modified Shingle component is an excellent selling feature of this shingle, not to mention the Zone nailing technology and the performance of the Malarkey Legacy.

The Malarkey Legacy shingle also has the 3M Scotchgard Algae Resistance and Malarkey allows Low Slope Roof installation to 2:12 as long as the Malarkey Shingle Installation Specification is followed.

Malarkey Highlander Review

The Highlander series are a asphalt laminate shingle which are considered by Malarkey as their “economical shingle”.  The cost savings of this shingle are the primary reason to not choose the Malarkey Legacy. It is important to note that the Malarkey Legacy is not an expensive shingle – but the Highlander shingle from Malarkey is most definitely a great cost effective choice if cost is the determining factor. The Malarkey Highlander would compete with shingles such as the IKO Cambridge laminate and the BP Harmony laminate shingle.

Malarkey ECOASIS Shingle Reviews – ECOASIS Premium AB Shingle (SBS Modified Shingle) and Malarkey ECOASIS Shingle (Asphalt Shingle):
Due to having never installed the Malarkey Solar Reflective shingle offerings named ECOASIS and ECOASIS Premium, due to the market being primarily based in the US, we are unable to provide an accurate and honest review. However,  GRS has great confidence in Malarkey shingles so we are very confident the ECOASIS shingle series is excellent.
Malarkey 3 Tab Shingle Reviews
In regards to reviewing the Malarkey 3 Tab Shingle offerings, there are not many comments to be mentioned as all the 3 tab products are of excellent quality with no conflicting qualities. We have not had many experiences with the Dura-Seal Malarkey (Fiberglass mat with Asphalt Shingle), yet we can say for certain that the Hurricane SBS Modified 3 Tab and the Malarkey Alaskan SBS Modified 3 Tab shingles are excellent choices.

Problems with SBS Flat Roof Installation

From our Calgary branch comes a report detailing problems that can arise from a poor SBS roof installation. Our roofing services are available in Toronto, Calgary, Red Deer, Edmonton, Lloydminster, Saskatoon, Regina, Medicine Hat, Lethbridge, Canmore, Kelowna, Vancouver, Whistler and points between.

 

Problems with Repair 1
SBS Modified Torch on Roof / Residential / Many Problems with Installation of Roof

Here’s a report from the field today in which one of our flat roofers in Calgary, AB had run into classic torch on (SBS Modified Bitumen) flat roof installation problems. Of course, for the homeowner that has a flat roof on their home that is paying the cost for improper installation practices, this is not a positive occasion. Nonetheless, the leaks on their flat roof will now cease and the homeowners will know that their flat roof repair is completed is in good shape to serve them well in to the future – it could have been worse!

Here’s the roof repair report;

“When I arrived I spoke to both the customer and his wife about the problems they were having with the roof leaking. I walked around the perimeter of the house and they had showed me the places the moisture was coming in to their home. The roof is a SBS roof – modified torch on. I found several problems; almost all of the roof membrane seams had no bleed out, I had bent down to check and observed cap sheet was torched down past the salvage edge between 1/2 and 1 1/2 inches, and the seam is sitting on the granules instead of torched down to the salvage edge. Where I pulled up on the seam or used a trowel I could lift it up. Also any corner of the sheet I wanted to I could pull up as well. The real kicker is the perimeter edge around the whole roof was completed wrong – the people that did the roof replacement did not prime the perimeter flashing when torching to it so it does not stick to the metal at all. Also I found the capping membrane was not buttered in at the metal so there is no termination point at the roof metal, the roofing installers didn’t granulate it either because it wasn’t torched properly. The homeowner had put some sort of water proofing gum or mastic around the perimeter of the roof and has stopped whatever problems they would have had earlier, but over time (no UV protection i.e. granules) the roof is starting to crack and the roof is failing and leaking – leaks from the improperly torched roof. I had observed in one location on the roof where the SBS meets the metal at a lifted corner – I pulled it up and saw that it was a definite leak spot so I temporarily repaired with mastic and granules. The chimney and vent stack should be re-caulked as well. The home owners were very happy I was there to figure out their problems with the roof and to explain to them how and why they are having roof leaks that require immediate repair. I also told them the office will be in contact with them with reports, pics, quotes and costs for permanent repairs to the roof. ”

Roofing in Western Canada Has Been Unusual This Spring

Our roofers in Calgary, AB were yesterday enjoying the spring weather and getting back to work before a large wind storm arrived. The storm literally blew roofs off houses – just when our Calgary roofers thought spring roofing season was here. There are roofs damaged all over the city – shingles were flying everywhere yesterday.

The Calgary Herald ran a story this morning:

http://www.calgaryherald.com/news/Windstorm+causes+damage+across+city/4598487/story.html

And then, just when our Alberta roofers thought their roofing projects would gear up full steam (I know our Project Management had every roof project perfectly laid out and scheduled with the roofers booked), mother nature sends the roofers one last spring surprise. 10 – 15 cm of snow are expected in Calgary, Red Deer, Leduc, Edmonton and other areas of Alberta over the next 48 hours – once again the roofing projects will grind to a halt and then start again for a few days before the spring rains come – a roofer’s life. The Saskatchewan roofers look to be in the best shape to get roofs done over the next week as the Vancouver area roofer’s will be dealing with 10-15 mm of rain a day over the next few days.

The season will get under way for our roofers soon and when it does I suppose we will just have to get more done with about one month now missing from our roofing project calendar for 2011.

Which brings this roofing weather blog to one last point, or a tip for those considering a re roof on their home this spring.

Storm Nailing Shingles and Ice & Water Roof Underlayment

When you hire your roofing contractor to re roof your house this spring, be sure the roofers storm nail the shingles. Every roof should be storm nailed, because you just never know when the storms will come as evidenced in Calgary yesterday. And a high quality roofing underlayment will go a long ways when your shingles fail to protect your home and keep the water out.
