old house, new metal shingle roof, new water problems
Comments (1)Did they place a water and ice shield barrier on the edge of the roof to three feet past the wall line? Your roof is not similar, only the material is. Original roof was solid from eave to ridge so any ice formed would just keep backing up the roof without penetrating. New roof is pieces which allow the ice to form and move underneath and then leak in the house....See Moregot bids for new roof....either shingle or metal..need to add ins
Comments (1)My best suggestion is that you figure out your priorities. You may want great insulation and a durable roof that looks good, and you may want it all for cheap. You probably won't get all of this. If you don't prioritize then you won't know where to compromise, and you'll keep going in circles. Also, try and find a professional to work with who actually understands the way your roof is supposed to work, or else you'll just be throwing money away. For example, if your roof is ventilated then any insulation you put on top of the existing sheathing will be pretty much useless. You probably need a smart general contractor, not a roofing company....See MoreRoofing- Metal or Shingles?
Comments (20)My brother has a metal roof. The guest bedroom is on the second floor with a vaulted ceiling. I do not sleep when I am a guest there. Sound of rain on "some" metal roofs are torturous to my ears. Something not mentioned here is the sound, the sales guy that pitched me said with his roofs sound is not a problem, he wouldn't put into the contract that I would get a 50% rebate if the sound of rain could be heard within the home. Maybe my brother doesn't want overnight guests. It's an old thread but added that if someone is using this for research....See MoreYes or no --- putting a metal roof over one layer shingles
Comments (11)There is not " a single "correct " way of doing a metal roof but here are a few thoughts for your consideration. I am taking you at your word about being familiar with construction because much depends on your ability to apply experience to which way to go. Be certain the one saying two layers is honest as well as experienced before sighning a contract with him. Most properly installed composition shingles look like 2 layers at drip edge because of starter strips. Can you install metal over one layer of composition? Maybe. The main consideration is wherther the deck and frame will support the extra weight. Then there is the question of how smooth and level surface the shingles afford. Regardless of other underlying material,decking must be capiable of holding screws. 1x deck is strong but usually has many gaps between edges and ends of boards that if a screew gos through,a leak is likly. OSB and plywood are flat and smooth but must be thick enough to prevent flex between rafters. I have installed metal over a few compostions with no problem after several years. On a couple where shingles were aged and deck was strong, we layed tar paper between the shingles and metal. Another had heavy truss framing with questionable decking so we installed 2x4 laths over tar paper making certain to hit rafters with lath fasteners. If your husband is a healthy 70 yo,you might consider hireing laborers to work under his supervision. I agree with Hollysprings about metal not being difficult compared to other construction tasks. A word of warning about roof tearoff. Think twice about putting old shingles in anything without dump. The shingles interlace and make the intire load act as a single blob that resists shoveling off. If you use a non-dumping truck or trailer, lay a cross tie or similar on floor at front with heavy chain on it. If bed is more than 8 feet long, put another drag half way to back and leave enough chain slack between the drags to alow first to move a few feet and pull some material off before chain tightens on other drag. In farm and ranch country you may find people who have installed metal as part of thier farm work. A farmer or rancher who has built thier own barns might welcome extra or off season work. If that sounds interesting,in addition to other means of asking,check out the people on "Yesterday's tractor forums". The board you want is "tractor talk" . If you go with diy ,you can buy or rent the specialized cutters. If your husband decides to supervise labor and isn't comfortable on a ladder and/or walking on the roof,rent a lift to alow him safly going to roof level as well as saving time lifting materials....See MoreUser
