looking for some communication from those who have washed this. we have an erstwhile barn that lost a lot of shingles this summer and If we want to proceed it in good shape take to reroof it. priced having information technology done but call up we can tackle this ourselves without as well much trouble if we get going before winter arrives. thinking of doing it ourselves and going with metal roofing vs shingles which it has now. and so continue on in future with metallic siding instead of having to paint regularly. some questions.

how heavy a guage metal should we use
any suggestions on profile types? are some better than others?
wondering nearly the gambrel roof and how to go about the seams where angles change
is this doable over the shingles? barn is plywood under the shingles. do we become rid of shingles and utilize metal roofing, if leaving shingles exercise we take to apply strapping (wooden strips)

basically looking to get some feedback from others who have done information technology before. weve done a lot of construction blazon stuff in the past just non metal roofing.

cheers

I have never done a gambrel roof but did my house 35 years ago. I shucked off the old shingles and re-nailed the pops. Doing it this manner permit me re-felt the ship lap decking with thirty# felt. I used 28 gauge 5V crimp galvalume nailed apartment to the deck. Nailing directly to the deck has let it come through unscathed 2 bad hail storms that dinged up other metallic roofs nailed to lathing.
Installation is like shooting fish in a barrel using screws or gasketed ring shank nails.
Hope this helps. Gil milofarmer1

The metal company has trim/flashing for the angle transition. Should not be a problem. It will go over the peak of the lower metallic, and under the upper sheets.

I highly recommend metal roofs, specially on a barn.

I redid a barn roof all past myself a few years dorsum that had onetime rotten shakes on information technology. Spent several days ripping off the old shakes, laid down new felt and screwed the metal downward. Went from a barn that was most to exist ruined by a leaking roof, to extending its life by several decades.

I used 24 gauge.

Do you lot mean hipped gambrel roof (hip)? Ours and everyone effectually here had theirs changed to metallic in the 1950's around here. Neighbours just had theirs replaced instead of renailing it equally they use the inside for a campground rec center.

I did my shop and lean-too (7/12 pitch, on 2x6 ) in metal too almost 7 years ago with the more modern cut to length sheets, and my female parent roof just got done concluding summer.

Of the options: My store has no sheathing, it was terrible working upward high on purlins on edge and the long sheets (xxx+ feet) fifty-fifty in heavy gauge tended to kink. Needed heavy to bridge the purlins.

The lean-to was put on purlins on apartment spaced much closer, on a iii/12 pitch, and was super simple.

My mom's roof was stripped to plywood to supercede some damaged sheets before underlay, strapped and steel. Super easy to walk on during the work.

Our barn had the forest shingles stripped on the roof with steel overtop of the 1x4/1x6 strapping. Its super steep until you go to the top pitch, hard to piece of work on with modern safety rules, we have had some quotes to practise work on information technology but nobody wants to touch on information technology.

Fifty-fifty 2/12 is unsafe to walk on wet, 7/12 you can't safely walk on even with clean dry out atmospheric condition in clean sneakers, you just slide.

The best attachment method then far is the shortest possible screw installed in the apartment. Near every leak I've ever had has been in a rib. Every leak in a valley has been simply besides long screws + woods drying out pushing the screw out like in drywall piece of work.

How do you get leaking if screwed in the rib? I did a very, very small lean-to roof and I thought information technology made sense to screw into the rib thinking that water won't be flowing down the rib like it would in the valleys (apartment)????? I started looking at other roofs and saw that everyone of them had the screws in the flat. I tin can't believe I was correct and everyone else was wrong, but, I never looked into.

I built a little shed for the sometime pickup in 2004. Based on this feel, I am going to suggest a metallic roof. I would suggest removing the old shingles and checking the condition of the plywood. Do you have whatever rotted spots that demand repair? Should you re-nail a few spots? I would so use 2 1/2 or three" deck screws to install 1 X 4 lathing, 24 or 32" on center over the plywood. The deck screws should be screwed into the rafters. You tin then install the 26 gauge metal covering over the lathing. Like other posters mentioned, install the screws in the flats. You can remove a 5 - vi" wide section of sheathing where the drop shed joins the master roof. The end of the metal drop shed roofing panels can be turned up at least 2" and extended under the more vertical sheets of metallic. It volition be best if you can caulk this seam from the inside. If you lot await closely at the fastened photos, you lot tin can see that a 12" broad transition strip was installed where the two top sections of covering join. The end of the roofing panels were turned up where the ridge cap was installed. Too, note that a cap was installed over the edges of the roofing.

On August 29, 2005 this barn took over 4 hours of 90+ MPH wind and over 8" of rain during Hurricane Katrina. The barn and roofing were not damaged but I did have water blown in around the windows. Likewise, I had some water blown in where the sections of roofing join. I have not had whatever leaks during normal rainfall events.

I think it is because you lot tin can't pull the screw down tight against the rubber without dimpling the rib. slowzuki

My shop they are in the rib and the drawbacks are:
i. Too loose they leak a really surprising amount.
2. Besides tight they kink the rib and leak a surprising amount, and the only ready is mess gobs of silicone or tar.
3. Too uneven tension from pinnacle to bottom makes an uneven spread on the ribs and information technology doesn't accept much. From having a top guy and lower guy when doing my shop nosotros were off 3" elevation to bottom along the 68 ft of roof.

Pluses:
i. With long sheets the rib gives a length of screw to tip over when the sun heats the steel up and grows longer. In the valley it will tear the hole a tiny bit oval.
2. No others.

Just built a gambrel hither this summer. The lower hip we used some pre-formed flashing. Upper hip we merely slid lower run of metal up under upper run of metal (we take done that on several buildings with good results). Screw metal in the valley, non on top of the rib. It's hard to maintain tension on the ribs and not cause the metal to "run". All the suppliers here recommend screwing in the valley.

I have done a off-white number of these barns. I would put strips on top of existing roof 1x4s. I would even consider them over the plywood if you tear off. Your screws have more to grip into. And nothing rubbing on the steel like a loose nail. Sometimes on tall steep jobs we get for 2x4 strips just because they are easier to walk on and not too much more. Also rent a telehandler and a piece of work platform. It volition brand the chore so much easier and safer. dmh

I take done my fair share. Nosotros always stripped with 2x4 nailed on with pole spikes to rafters over the shingles, a few nosotros tore off simply not many. You can buy flashings for the hip or just run upwardly to the other without touching let the top hang over a few inches. Never spiral tin on the hump ,except stitch screws or when putting on trim. I seen somebody mentioned a telahandler ,damn I wished we would accept hade one, did use a hyd elevator to repair some can on tiptop once. If you don't have them options, when yous go to finishing end, put trim and finish piece of tin then last full piece and nail on way downwardly with one foot nether tin on purlins and kneeling on the new tin with other leg its nice to have a guy beneath you 2 rows helping folding tin up.
