Oggie Posted January 30, 2013 Report Share Posted January 30, 2013 My cottage (camp) is a remote area that's hard to get at in winter. The roof needs replacing and I'm wondering about a metal roof vs asphalt shingles. Any roofers on here?? I need to know the cost per roof square for a metal roof vs a shingle roof? How hard is it to do a metal roof? The camp is only about 20' by 15' with a cottage roof (ie. four sides that come to a common point), Thanks for any infor or help. Dan O.

BillM Posted January 30, 2013 Report Share Posted January 30, 2013 If you don't want to roof it again, metal for sure. Link to comment Share on other sites More sharing options...
fisher Posted January 30, 2013 Report Share Posted January 30, 2013 I'd be curious about the sound of rain on a metal roof while sleeping. Link to comment Share on other sites More sharing options...

bushart Posted January 30, 2013 Report Share Posted January 30, 2013 if you strap over the existing shingles and put metal on that---the old roof dampens the sound a bit Link to comment Share on other sites More sharing options...
F7Firecat Posted January 30, 2013 Report Share Posted January 30, 2013 Never put a metal roof over a existing asphalt shingle roof, strip off the old roof theres too much weight when you consider a layer (or two) of asphalt shingles, strapping and metal roofing. Especially on camp roof that in the winter may see a large amount of snow load, with no one there to shovel it off when needed. Link to comment Share on other sites More sharing options...
Muskieman Posted January 30, 2013 Report Share Posted January 30, 2013 Strip old singles off , apply self sealing waterproof membrane , steel roof ... never to be touched again ... looks great , sounds even better under rainy skies . Link to comment Share on other sites More sharing options...
Oggie Posted January 30, 2013 Author Report Share Posted January 30, 2013 It's a good pitch so I was kind of hoping the snow would break free every now and then to reduce the snow load. If I have to remove the old shingles I might just go with shingles again. It's a 70 year old log structure so the metal roof would outlive the life of the building. dan O.

bushart Posted January 30, 2013 Report Share Posted January 30, 2013 (edited) Strapping and the metal's weight is negligible overall if your concerned about it We strapped over our cottage roof (Shingles)--15 years ago---put metal over that---zero issues---between North Bay and Huntsville---l'il bit of snow---no shovelling Look at the area for snow loads-----look at the Sault where some roofs have 3 feet of snow on them------ Who's shoveling your cottage roof now with just shingles??---fall in yet?---snow likely sticks on those shingles as well That metal is not as heavy as you think---try hanging onto one sheet on a windy day----ultimately your call. If it's a cottage style roof----whats the pitch---7/12?---if so snow comes off quickly try walking on one with metal I would not apply metal directly to shingles though.

Muskieman Posted January 31, 2013 Report Share Posted January 31, 2013 Take the shingles off , it shouldn't even be questioned , what if there's rot under them ? Don't skimp out on the waterproof membrane , and no.. You can't put it over shingles , do it once do it right .. The steel roof would be the last roof that that cottage will ever see .

All this expertise Yes you can put them over shingles Who cares if there's rot underneath them The strapping will grab every truss above the shingles and be the support for the metal roof Not the plywood or boards underneath the shingle If there's a concern that the trusses are comprimised---a quick trip into the attic space will determine-----if there's a truss problem---re-roofing of any kind won't help Link to comment Share on other sites More sharing options...
Muskieman Posted January 31, 2013 Report Share Posted January 31, 2013 (edited) I meant that you can't put a membrane on top of shingles . I would for sure care about rot ...I wouldn't put Bondo or a sticker over the rusty spots on my truck .. *edit impaired typos. .

bushart Posted January 31, 2013 Report Share Posted January 31, 2013 OK this is getting tiring I see most provide only opinions---I gave info from the metal roof supplier at the very least So I'll take my years of schooling---- 4 Ontario Provincial licences in building trades----One Interprovincial----29 years experience in construction/maintenance trades and concede that opinions are like fishin rods here---everyone's got one So I'm quittin and say I'll just graduate from the OFC college of knowledge Link to comment Share on other sites More sharing options...
Muskieman Posted January 31, 2013 Report Share Posted January 31, 2013 No bashing or upping ... It's just what we did at my brothers cottage this past summer , old shingles off , found rot on the roof boards , replaced them , applied membrane and green steel roofing , chimney and two roof vents . Sorry Bush , I never disagreed with you ... just stating what I'd be worried about . Link to comment Share on other sites More sharing options...
Oggie Posted January 31, 2013 Author Report Share Posted January 31, 2013 Thanks guys. Bushart my camp is on the same latitude as yours. The roof has never been shovelled so metal would be an improvement especially once the warm, sunny days of March show up. I hesitate to remove the shingles because they can't be disposed of any where nearby (I'm in the Park). They'd need to be trucked to Pembroke which is 50 miles away down a gravel road. The roof doesn't leak and I figured the existing shingles would be as good as a membrane underneath once the metal is installed. I would strap the roof first for sure. Anyone have any idea as to cost for metal vs asphalt? I'm hearing double the asphalt cost to get a rough estimate. Thanks again. Dan O. PS> I think we're all getting Cabin Fever with this weather!

John Bacon Posted January 31, 2013 Report Share Posted January 31, 2013 (edited) Adding a metal roof over shingles should reduce the weight load, not increase it. Snow doesn't stick to a metal roof; the strapping and metal will be lighter than the snow that sticks to shingles. I was never bothered by the noice on my parent's cottage which had a metal roof over shingles. My brother doesn't seem to have an issue with noice at his cottage which has a metal roof with no decking. My parents went with large metal sheets over strapping on top of the existing shingles. I did notice more bugs in the cottage after that. I would look at metal shingles instead of the large sheets. You should also remove the gutters from your roof if you go with metal; other wise the snow will take them off. I have seen some roofs with metal "brakes" installed to slow the speed that the snow slides off the roof.

rickster Posted January 31, 2013 Report Share Posted January 31, 2013 Not sure of prices your way but up here lifetime architectural shingles sell for 28 dollars a bundle and colored metal sells for about 95 cents a square foot so pretty close in price Link to comment Share on other sites More sharing options...

Have you much experience with installing metal roofs? Considering the costs involved, maybe it would be beneficial to seek advice from a reputable metal roof installer?

scotty61 Posted February 2, 2013 Report Share Posted February 2, 2013 Just me 2 cents worth. If you planning on doing it youself, metal sheets can be ordered in any length you want. However if your roof come to a single point, there will be a lot of cutting involved, unlike a standard 2 sided roof. Like Johnbacon mentioned, snow brakes or cleats are a must before any roof protrusions like chimneys, antenaes etc. Once the snow releases, it comes down fast and hard, wiping out anything in its path. (Don't ask how I know this ). Nice to have them over the entrance too, if you use the camp during the winter. Once the snow falls it packs down pretty hard. ...Scotty Link to comment Share on other sites More sharing options...
