A roof on one building did not make it through the winter. The finish layer is beginning to delaminate. It is only one layer thick. I am inclined to remove the current roof and take it down to the decking which is plywood and then put new shingles on. Do you generally keep adding on top of old roofing or do you take it down and start over. And is there a brand/ spec of shingle you prefer to use? --24.194.xx.xx |

Strip it is way better,then you can see what the decking looks like,also some cities don't allow 2 layers anymore which just adds to the weight --72.231.xxx.xxx |

Remove all shingles, so you can see and replace sheathing as necessary. Us architectural shingle for the new roof - much more durable than flat, 3-tab and not really more expensive. --68.10.xxx.x |

Remove the old layer if you are going to reshingle. If you are using a metal roof, run battens over the shingle and attach metal to that. --108.4.xxx.xx |

Upfront a metal roof is more expensive but over the long term a metal roof costs less as a metal roof may last three times what shingles can. Suppose there are high winds where shingles blow off. Metal roofs come residential grade, medium grade and commercial grade where it is not that much more expensive to go commercial. Shingles is renting a roof where repairing and replacing. The straight metal panels are the lowest cost. Measure out then price out materials. Here many roofers go out buy the builders grade of shingles which does not last long. Check out some videos on You Tube about metal roofs then can be more informed. --147.194.xxx.xx |

Remove all shingles. Use ridge venting if possible. Use architectural (aka designer) shingles. If roof slope is 3/12 or less, use either ice/water guard on the entire roof or increase overlap of shingles per instructions. Use drip edge to avoid fascia rot/damage. If you change to ridge venting from gable vents, block off gable vents to avoid "short circuiting" of the ventilation system. Ensure you have soffit vents or create them...most homes since the '60s have it already. --99.92.xxx.xxx |

Thanks for the feedback. I was way leaning on tearing it off, just thought consensus might say otherwise. Going over it is what a roofer suggested. I am pretty sure the decking is good, since I can see it all in the attic. By me lots of hail, but I am reluctant to go w/ metal. I have an entrance on the side and all the snow will come sliding off in big heaves (happens at my place). Don't think there is a covered entry I could build to take that. As it is icicles form and make the walkway icy, which raises a question about gutters in the NE.
Do you have 'em or not? This property did until they were torn off by the snow, so I didn't put them back up. Don't think I'm prepared to invest in insulating to separate the roof from the conditioned space. Thoughts? --24.194.xx.xx |

Roofers will often tell you to use a second layer so that their “comes in lower than the next guy and they get the job. Also some shingle manufacturers will void warranty if you have multiple layers.
Roofs are only designed to handle so much weight...you put two layers of shingles and then a snow load and u may be asking for trouble.
Don’t worry about ice sliding down metal roof...good roofers will install ice breakers to prevent this.
Gutters (and downspout extensions at least 5 feet) are needed to direct roof water away from the house..especially with basement or crawl space houses. Water near the foundation is a major cause of foundation problems but it happens slowly over years so most people don’t notice it --99.92.xxx.xxx |

If you are getting icicles, it means that warm is getting to the roof decking (attic space) enough to melt the snow. Then as it gets to the edge where there is no warmth it freezes. So yes, insulating the attic will help there. Be sure to leave the venting to keep it cool in the attic.
Snow guards, snow stops, ice birds, snow brakes... all names for the item attached to the metal roof that will stop the snow from sliding off. Pitch of the roof also makes a difference in the snow sliding too, steeper pitch, easier for snow to come off. By putting the metal roof on the one inch boards and not on the actual decking itself, you also have an airspace under the metal that helps with ventilation.
Metal roofs even come in shingle look if you want to go the extra expense or don't want it too look like metal. But there are so many advantages to metal, and not having to tear off the old with the mess and disposal costs is also a bonus. --108.4.xxx.xx |

small potatoes, your last post confused me. Are you saying the attic is conditioned space? If so, you need good insulation in the roof itself, nowadays the new techs are leaning towards sandwiching a couple of layers of foam board in the roof, a natural for metal top. --174.21.xxx.xx |

Insulating directly against a roof is tricky...have a pro do it. Depending on climate may need a radiant barrier or an air gap between roof decking and insulation --99.92.xxx.xxx |

CX the attic has the forced air furnace for the upstairs apt on one side so it generates heat. My icing problem is actually on the other side over the unconditioned staircase, go figure.
The roof is steep, saltbox style but slightly steeper. A deicing cable is what I should put along that stretch, and perhaps do the bottom 3' or so in metal. A larger project would be to add in vented soffit.
Still not convinced gutters make sense w/ a steep roof. --24.194.xx.xx |

Assuming you are talking about the 2 story houses typical in your city I don't generally see gutters on those houses and think it would cause more problems than it would solve anyway.I think I would stick with shingles,if you put metal up there the roof is so steep the snow would come off like a slate roof,all at once and dangerous if it hits someone --72.231.xxx.xxx |

small potatoes [NY], I agree most times gutters are more trouble than they're worth. On some of my places I use a 10' or so length of 6" aluminum gutter without any end caps or downspouts over the door ways. Under the ends of the gutter where the water lands, I use some crushed stone to help prevent splashing & to control runoff. --96.237.xx.xx |

I think heating cable is my best choice and if there is hail damage then my cash value policy will work in my favor the first few years. My area is tied for the nys record hail size of 4" in 2014. Came down like tennis balls. Amazing it didn't do more damage. Travelers and such came through and were plenty busy --66.87.xxx.xxx |
