A. Tested & Proven, Dr. Shields Canadian Roof Armor is a clear acrylic spray-on shingle protectant manufactured specifically to extend the lifespan of fibreglass shingle roofs. It does this by glueing the granules to the shingle and by stoping water infiltration into the asphalt which in turn stops the oils from leaching out. Also proven to be very effective on torch-on and tile roofs.
A. Yes, Dr. Shields Canadian Roof Armor is a permeable acrylic allowing the roof deck to breath. Your attic should be breathing through your soffits & roof vents.
A. No, this is a tested & proven product designed specifically to extend the life of fibreglass shingles by simply stopping granule loss and the drying out process of the asphalt.
A. This is caused from the tiny ceramic stones (Granules) dislodging from the sun, rain, wind, ice, snow, hail, moss. Once the ceramic stones or (Granules) come off, the layer of asphalt is exposed to UV rays. The asphalt dies out even with the granules in place however the drying out process snowballs as more of the granules due come off the shingle which then quickly dries out, curls, cracks, which in turn promotes faster granular loss on the rest of the shingle. And around, around it goes, until the shingles are completely dried out past the point of repairing, cleaning or weatherproofing (sealing).
A. Shingle manufacturer warranties cover manufacturer defects only. Manufacturer defects are not specifically disclosed in their warranty literature. They do state that if a manufacturing defect occurs along with a leak and if you can prove it, then you have a warranty claim. The term 30, 40, or 50 year shingle does not imply from the manufacturer that the shingle will last that long. For whichever number length (30 year, 40 year, 50 year) any shingle manufacturer's chooses, their limited, prorated warranty, will only cover manufactures defects, not durability. By the time (15-20 years) your roof has deteriorated naturally you will probably never have a manufacture defect on your roof. Do not be mislead. Durability is up to the owner and the only way to make a shingle more durable is to weatherproof it with Dr. Shields Canadian Roof Armor.
A. No, normal weathering (Granule loss, asphalt drying) is not covered in any shingle warranty.
A. Our 10 year warranty gives you the coverage you were looking for, covering durability of the shingles themselves. We project that the lifespan of roof shingles will at least double just with one coat.
A. Dr. Shields Canadian Roof Armor trumps the manufactures warranty by stopping the very thing that the shingle manufacturers do not cover, normal aging, weathering, drying out & granule loss. Durability.
A. Shingle manufactures are not as interested in your roof lasting, as much as you are. If the shingles lasted to long, they would not sell as many.
A. Slippery when wet, yes. However a professional will have the proper equipment and footwear to walk on any roof in any condition. When the roof is dry it will actually be easier to walk on then if your roof was not sealed. When your roof is not sealed the granules slide off from under your feet making it hard to make a sure foot. When roof shingles are sealed this does not happen. We recommend wearing deck boots, or a flat, soft souled shoe/boot.
A. No, if a roof is to dried out with the edges curling up, you are better off to spend your money on a having a new roof installed & then sealed. However if you do catch it in time you will add years, save thousands and you may never have to re-roof again. In areas with more granule loss simply apply extra sealant.
A. It is not the age of the roof rather the condition of it that determines weather sealing is beneficial or not. If you are uncertain about the condition of your roof we will arrange to inspect it to determine if weatherproofing will be beneficial or not. Rule of thumb is before the edges are curling up.
A. Yes, however your roof in this case must be cleaned (de-mossed) using water & low pressure to safely prepare the surface area for weatherproofing (sealing). The Great Canadian Roof Doctor Specializes in Roof Cleaning & Sealing (weatherproofing). You can also do it yourself just use common sense.
A. No, you should never use chemicals to clean shingle roofs. Cleaning chemicals dry out the asphalt in the shingles faster then the natural drying process. The Great Canadian Roof Doctor Inc. uses only water & the appropriate pressure along with the a bag full of experience to safely prepare the roof surface for sealing.
A. It is true that bleach will clean your roof. The problem is that, if the asphalt in shingles dry out naturally on their own, then it only makes sense that bleach will accelerate the drying out process. This in turn also accelerates the granule loss. This is NOT a responsible recommendation and should not be followed. Even if the shingle manufacturers do know that their recommendation is aiding in drying out your roof, we must ask ourselves, is it in their benefit for shingles to dry out? Well, yes it is, because they in turn get to sell more shingles.
A. Of course we don’t recommend that just anybody set out to clean a roof using a pressure washer. With water & pressure you can cut through steel, conversely you can blow the dust off a book, depending on the amount of pressure, the attachments, & the technique performed by a trained professional. Roof cleaning is a very delicate job and should generally be done by someone who is comfortable with the task. We have talked to many homeowners who have had no problems going up on their own roof using a pressure washer to clean it. Common sense is a big one here. Start with low pressure, use a fanned tip, shake the want fast enough so you are not in one spot to long and pay close attention. Its not rocket science. Just a lot of hard work. Those who are not afraid of hard work will find much good can be accomplished with this method, especially since the surface is prepared for the clear acrylic spray-on roof sealer.
