Description of Work: The precipitating decision to replace our 30-year old asphalt shingle and rubber roof with a metal one came with ice damming problems during the cold and snowy winter of 2015. The process for us took some time, from initial estimate (May 2015) to final installation (March 2016), but this was a result of a combination of factors on both the installer's and our parts. But once we finally settled on an installation date, it took a very professional crew led by Tom (foreman) about a week and a half to strip our old roof, modify the roof configuration and venting, and install the new aluminum one. | |Our home is a relatively small 3-bedroom cape, with a first floor extension that was previously added to extend the rear of the original home for its full width, including a middle basement extension and concrete crawl spaces on both sides. This rear extension is covered with a low-pitch roof with a cathedral ceiling over the back third of three separate rooms. Two rooms already had skylights in the low-pitch roof, which we replaced with fixed Velux units, and we added an additional identical skylight to the third room. Our initial estimate for about $30,000 (not including the new skylights) was to replace our peaked roofing with Oxford Shingle in Forest Green and replace our low-pitch roofing in the rear, over a side porch, and over a front bay window, with standing seam, also in Forest Green. This included a replacement roof vent for a bathroom exhaust fan and an additional roof vent for another exhaust fan on the 2nd floor that exhausted into the attic, as well as snow breaks along 20 feet of our front peaked roof. We also had two Velux GPL roof windows in the front peaked roof on the 2nd floor that we decided to keep, as they are relatively new and are no longer available in the USA, and to which Tom's crew would add new flashing. Similar flashing was added to three existing Velux sun tunnels on the rear peaked roof, which provide port holes for our "boat room" on the 2nd floor. | |To this, we very quickly determined the need for a change order after the crew arrived and we consulted with Tom about how to vent the low-pitch roof. As it was, this particular roof had just three small vent pipes for the roof itself (plus three plumbing vents in total) that provided very little roof ventilation plus a baffle running out to the side-porch ceiling, which is also vented. However, our attic on the 2nd floor had almost no venting, just one small knee wall vent at one end of the house. So, at Tom's suggestion, we decided to add a cold roof to the existing low-pitch roof with R18 of additional insulation topped with baffles running from new soffits all the way into the rear of our attic, which would effectively vent that half of our attic for the first time by taking advantage of existing baffles and ridge vents. We also added a new custom-built soffit vent to a front gable dormer whose lower width covers half the front of the house and would provide much needed ventilation for the front of our attic, and which then had only one of existing knee wall vent, similar to the rear attic, but at the opposite end of the house. We also added a short snow fence to the side porch roof. The entire change order, plus the three new skylights, added about $10,000 to the original estimate, on which we already had made the typical 1/3 down payment. | |With all of that, as I said, the installation took about a week and a half, and there were some glitches. One of the front GPL roof windows needed some attention after the work was complete, because its lower cladding was caught on the lower flashing preventing the window from opening. When we finally got it open, we found that a side flange of the window was bent out of shape, preventing the window from being properly closed. Tom took a ladder up, and standing only on snow breaks, he did all the work to free the cladding from the flashing and disassemble and re-bend the window flange close to its original shape to allow the window to properly close, then re-installed the flange and re-attached it to the flashing, all while precariously perched on these snow breaks! | |We also had a couple of problems with booting two of the three plumbing vents (these vents and their new boots unfortunately ended up directly over standing seams), which the crew boxed in with some additional standing seam roofing that works as a kind of "covering" flashing. Finally, we had a stack extension installed on a third plumbing vent whose diameter was too small, leaving the extension high up on the vent pipe, where it quickly tipped over, but not quite off the pipe (thank goodness). I took a photo of this "mistake" before removing the poorly-installed extension and emailed the photo to Bryan, my account rep at Classic Metal Roofs. | |Adding this badly seated stack extension was the last step in the entire job, and which I'm afraid was hastily done just before rain fell, and was no doubt left for me to complain about after the fact. I must say that Bryan has been very responsive, and I feel somewhat confident that someone from his crews will return to replace the mis-sized stack extension, which should slide all the way down over the existing pipe for a secure and caulked fit, exactly like another vent pipe extension that the crew did install successfully. (This last item has yet to be completed, and I may comment further on how that went.) | |Otherwise, on the whole, I think their work is excellent. They use a very high end snow and ice shield as part of the flashing work for just about everything and cover the entire roof under the aluminum with a tough tyvek-like (but even stronger) underlayment. The new skylights are superbly flashed, as well, using a basically aerodynamic form designed to channel ice and snow around the skylights. And they do an equally thorough flashing job around dormers and in every other location where water could get in. | |Tom answered most all my questions patiently knowledgeably and his crew even made some additional cosmetic touches that I requested at no additional charge. They also cleaned up superbly after every work day, ensuring the the roof was secure and water tight, no matter its state, and finally leaving the entire yard almost as they found it. I am left only the task of using a blower to clean some dirty boot prints and bits of old roofing and insulation off the low-pitch standing seam, which rain and opportunity has prevented my doing so far. (Tom would have done the latter, except that it started to rain at the end of the job.) | |We've had both rain and snow since to get some idea of the roof's effectiveness, which so far seems excellent, although it will take another heavy winter to really run the roof through its paces. The forest green was also an excellent color choice for our otherwise white house, which is surrounded by a number of tall trees and green landscaping. |
