The greatest invention since sliced bread is that of an inline down pipe clean out. We installed half a dozen of these today in Burnaby. You no longer have to worry about going on the roof and keeping your drain’s ball screens clean. These clean outs even work on eavestrough down pipes. We now want the debris to go down the drain but we catch it before it goes into your drainage system underground. Would like meat on that sandwich?
This photo attached is of an old bathroom fan ducting section we removed today in Burnaby BC. This whole section of ducting is hidden from view. It is up in your attic and in behind the soffit screening. So to analyze the ducting – the top left is where it joins to the fan housing and where the fan motor is… so you can see that it is expected that when the ducting does a 90 degree downturn it is required that the moist and warm bathroom air must travel about 12 inches straight down towards the ground before it even has a chance to exit the ducting. Logic says, even with a very high powered fan, this route is difficult enough to perform never mind that the old installers now expect the moist bathroom air to then travel horizontally a distance so it escapes the coverage of the soffit overhang before it is free to dissipate into the general air. How do the original installers think this is possible without allowing some, OR ALL, of that moist air back into your attic space? It simply is not possible. That is why we re-duct bathroom fans, and kitchen hood fans, to a vertical configuration. We know warm air rises so to vent it up and out through the roof is the best. There is only one reason for builders to not do it the correct way. That is cost. It is simply put, easier and cheaper to do a horizontal ducting then to do it the proper and obviously necessary way. Call Greg @ Crucial Roof Services for more information on this and other design failures that builders have done to your home.
Finding leaks on tar and gravel roofs is not an exact science. But once you have found them what is the next step? In most cases it is raining out or the roof is wet so you can’t put down a permanent patch. That means you have to put something onto the split or roof hole that will stop the leak and works on wet surfaces. The two most common tricks of the trade are either using a Portland cement or a Bentonite clay mixture. I choose the clay. Here’s why. They both stop the leak initially. But the cement forms and solidifies into a clump that does not change shape. So once it’s formed it stays that way. The problem being is that when it completely dries it releases it’s grip in the roof and becomes separate. Thus the leak or roof deficiency is now open again and prone to further leakage… Except it’s got a clump of cement over top of it! The clay works differently. It too does dry and somewhat release it’s grip on the roof over time but it reactivates with the next rain and turns back into the thick slurry that stopped the leak the first time. Essentially it is reusable on the same leak. But to be completely honest… you need to get that roof leak upgraded to a permanent patch as soon as possible. Don’t leave the temp patch on too long and test it’s performance abilities. We dropped some clay on a roof leak in Richmond and also in Burnaby today. This is what it looked like.
Concrete tile roofs are supposed to be installed with a minimum 3″ “headlap”. That is the lap distance from row to row. When that 3″ lap is not maintained, and especially on a lower sloped roof, a common problem is that of wicking. The water wicks up the underside of the top tile, past the top edge of the tile below, and drips onto the underlayment. Now one tile by itself doing this is not a big concern. But when an entire face of tiles is wicking it can add up to a substantial ingress. This is what was discovered today in Burnaby. The only resolution is to increase the coverage of the surface below by installing 6″ flat stock metal all along the lap…. for every row of tilers! Thereby we are extending the tile coverage to about 4″. Amazingly this works and relieves the home owner of the daunting task of re-doing the whole roof with adequate headlaps.
