Improper roof flashing with the use of cheap steel, which most roofers use is clearly the #1 cause of roof failure, and chimney flashing is the most neglected area of the roof.  Worse yet is the fact that many homeowners have been scammed into fully re-roofing their house because of these leaks, instead of just replacing that flashing. These fancy talking salesman are much more motivated to sell you a whole re-roofing to unsuspecting Homeowners to make that big ticket sale. And even worse is how they again will do this new work without the benefit of using better materials like aluminum or copper sheet metal flashing.</strong></p> <p align="justify"><strong>Most of roof flashing can be replaced without re-roofing the whole house, but of course that is far less profitable for a roofing contractor, so that is rarely offered as an option for your consideration.  These roofers know better, but they still do the same kind of roofing with this cheap steel flashing that they just tore off  of your house, that they know will fail in short order. It is said this is the definition of insanity.</strong></p> <p align="justify"><strong>If that were not bad enough, in most cases the roofing contractor's workers will still not re-flash those problem areas the right way, if at all, and the Homeowner get cheated yet again. Instead of flashing they will use the cheapest caulking (called mastic) smeared around those problem areas. Mastic is just fibered tar with no UV protection. This will usually get the roof past their minimum required 1 year warranty the Construction Contractors Boards require of any contractor, but not much more. This mastic tar will become brittle and crack, and peal away within a few years. If it were to be inspected by a State Code Enforcement Inspector, it would not be approved. They are not to use mastic anywhere on a roof. That is a clear sign it was not properly flashed. Mastic is a very messy emergency patch to pacify the leak until a proper fix can be made.</strong></p> <p align="justify"><strong>We know this to be an intentional crime of roofing contractors, since pretty much any roofer knows very well how common these issues are to find when doing a tear-off of an old roof; i.e. very rusty steel flashing on the roof.  When they tear into a bad roof for replacement, it tells a story of why this roof failed.  They would have to be complete morons to not see the evidence in front of them. Yet, they continue to ignore this evidence and continue do shoddy work, since in most cases they are not required to file for a building permit to replace your roof, and therefore do not have to worry about an inspector double checking their work.</strong></p> <p align="justify"><strong>Our Roofing web page at: <a href="http://dmr-gutters.com/fs/roofs.htm"> http://dmr-gutters.com/fs/roofs.htm</a> goes into more detail about this terrible issue.  So don't leave without reading it over, so you can save yourself a great deal of anguish down the road.</strong></p> <p align="justify"><strong>Over the last several decades so many roofing contractors with this cheap criminal mentality</strong><b> would not spend a few extra dollars on  aluminum flashing</b><strong>, so the suppliers do not stock it any more.  It can be special ordered from a fabrication shop like ours, but of course that makes it just that much more expensive than mass produced supplies.</strong></p> <p align="justify"><strong><u><font size="4" color="#800000">Solution:<br> </font></u>I originally built a sheet metal shop in my basement to custom fabricate my own custom flashing and paid the 5X cost for actual roofing liability insurance for several years, but with no employees I could not do the volume of work to afford it. Over the last decade it grew and evolve to building many different custom copper rain management products that can be seen on our web site here. We moved 5 times since then and the shop space increased to a separate 24' X 42' shop with overhead storage now days.</strong></p> <p align="justify"><strong>I use to be very intimidated by the cost of copper, so I used aluminum, knowing it is a lot better than the steel that is normally used, but I stopped using aluminum all together several years ago. The difference between using a cheaper metal is not that much considering the cost of the whole project, so it is not worth it to use a cheaper metal with all the work it takes to do this the right way. If done with copper you should not need to redo it again the next time it is re-roofed, or the next several times. Aluminum would last several decades, but the paint would flake off over time and begin to look bad, so it is not as reusable as copper. It would also crack more easily if the brutal roofer felt he had to bend it up to fit the step-flashing in under it as he re-roofs. Copper is much more malleable. Another advantage is how it will retard the growth of mildew and moss on the roofing below it.</strong></p> <p align="justify"><strong>There needs to be this 2 part flashing: the step-flashing is integrated with the roofing and sets up flush against the side of the chimney. Then the counter-flashing is mortared in between the bricks in horizontal lines only and overlapping the step-flashing. This 2 part system allows for the movement that is caused with the expansion and contraction of these 2 very different types of structures, while maintaining this seal. Of course the bricks will expand with temperature changes differently than the wood structure of the house. Even 1/4" movement would be enough to rip open any other method used to seal the chimney to the roofing. This is not a new method by any stretch. It is a time tested technique used for centuries, and I have yet to see a better technique for this purpose.</strong></p> <p align="justify"><b>Even high quality caulk should never be used to attach this counter-flashing, since it is just rubbery and adds no structural strength to the compromised chimney. As with the useless effort of tuck-pointing a chimney to make the mortar grooves look nice again; the new mortar in such a shallow groove has only the old crumbling mortar to stick to, so it will simply fall out within a few years.  The groove needs to be deep enough for the new mortar has the top and bottom brick to adhere to.  Anything short of that is a waste of time and money. These groves need to be ground a lot deeper than just 1/2". They need to be at least 1.5" to 2" deep and only filled back in with mortar.</b></p> <p align="justify"><strong><font color="#800000" size="4"><u>What If I Already Have This Kind Of Shoddy Workmanship On My House?<br> </u></font>If you are are a victim of this unethical business practice; you can show the contractor this web site. Then you should be able to deduct the cost of repairing your chimney and it's flashing even if you are going to do it yourself, plus the cost of cleaning off that black tar. I would encourage you to insist he has that tar removed and cleaned off as if it was never there by his workers. It is messy work and solvents on the roofing will damage the shingles and cause a terrible staining mess. If the contractor does it; he can then replace the damaged and stained shingles at the same time.</strong></p> <p align="justify"><strong>In the rare cases roofers do attempt to flash a chimney; in most cases a roofer will grind a diagonal grove into the side of the chimney right through the bricks and mortar to press the flashing into and caulk, instead of following the horizontal mortar lines and mortaring the new flashing in. This is a terrible way to counter-flash the chimney, because it sets up the bricks to fracture right there in an Earthquake, causing tons of bricks to be sent tumbling down off the roof destroying anything in their path. With this type of flashing work the bricks are damaged beyond repair. The only solution is to have the chimney carefully dismantled down to the roof line and rebuilt with new bricks. Do not let them talk you into any other alternative, trying to minimize the damage. They will try to discredit me and say I do not know what I am talking about, but it is simple logic they will not be able to BS their way out of it if you stand your ground. Roofers will claim that it can only be done this way when the chimney was first built by the brick mason, but I prove here that is simply not true. </strong></p> <p align="justify"><strong>Below are examples of jobs we have worked on that show the shoddy practices that we had worked to repair.</strong></p> <p align="center"><strong><font color="#000000">Click on the thumbnails for a larger better view</font></strong></p> </td> </tr> </table> </center> </div> <p align="left"><font size="1" color="#008000">.</font></p> <p align="left"><font size="1" color="#008000">.</font></p> <div align="center"> <center> <table border="2" width="750" background="../cc/tn/roof5.jpg" bgcolor="#DFCDAC" cellpadding="10"> <tr> <td bgcolor="#C0EAFE"> <p align="center"><b><font size="4">Solid 20oz Copper Sheet Metal Chimney Step & Counter-Flashing<br> </font><font color="#800000">(Click on each image to get a closer look)</font></b></td> </tr> <tr> <td align="justify"> <strong>Here is a step-by-step chimney re-flashing job I was hired to do in April of 2004 for a client Named Toni Ferro, who has this rental in S.
