Roofing issues


I don't deal with insurance and a lot of you guys back east do. Figured he would get better opinions from you all. I just wondered if this fell under weather like hail and such.

Roofing issues


Yeah I thought of insurance but don't think they'd cover it. Though this abnormal weather is definitely not helping, but bottom line is the roof should still be able to handle it. Also if insurance covers it, would they cover actually fixing the cause, or would they just cover fixing the damage? So far there's not really much damage. Once I fixed the cause I'll patch the ceiling, replace the insulation, and I'll be out less than $100. Fixing the roof on the other hand, I'll be out like 5k.

I will find out for sure tomorrow but my big hunch is that the first layer is solid ice. If that's the case, would it be safe to say it's a venting issue? I'm hoping that's what it is as that's cheaper to fix than a whole new roof. And since the plywood has absorbed water I'm thinking it will rot and will need replaced too.

A few days ago I was also hearing very loud bangs. Suspecting the plywood which was soaked with water was freezing. So this has probably been going on for a long time. This year the weather has been jumping so much that it just made it bad enough to leak. It's actually getting rediculous. One day it will be -20 and the next day it's like +10. Not normal at all to get heat like that in winter. Normally we slowly start getting heat by end of May, and the snow melts slowly, but this year it melts in large chunks, then we get another couple feet, melts again etc... I guess it could be worse, at least we don't get tornadoes, hurricanes or earthquakes here.

Roofing issues


I went in and pulled out two soaked pieces of insulation. Very awkward and complex operation just because of trying to stay on the joists while going backwards to go back out. I will have to go in there again, but I just had to take a break. I also found some mouse feces as a special bonus, and I'm pretty sure it was pee I was smelling. The drywall is exposed now so it can hopefully dry. I probably should have sprayed some benifect in there to kill/prevent mold growth, but it's awkward enough carrying the flashlight and insulation. If ever I build a house from scratch I'll make sure to make the attic easier to move inside. :o

My only concern right now is the fact that there is currently zero insulation in that area. Am I asking for trouble by leaving it like that overnight?

I also noticed that part of the attic does not have a lot of insulation, maybe R40 at most. I'd almost have to redo that whole attic with blown insulation. I also discovered something interesting that I never noticed before. I think this attic in indeed connected to my other attic. It's very hard to tell for sure though, but when I flash my light on top of the cubby hole to get into that attic, it looks like I can see the peak of the other roof through the insulation on top. This insulation is also very dirty which indicates air flow. So air is probably being drawn from the other attic.

I had mice in that other attic, so now it all makes sense, they were probably getting in through that leaking vent. Funny as last summer when I was on the roof I noticed that vent looked in rough shape and the flashing was lifting up. Figured it had probably been that way for a very long time and never gave it more thought. I probably should have fixed it.

I have a roofer that will come check out the situation on Sunday, so guess I'll go from there.

Idea #1
Looks like your ridge vents could be covered with snow and the soffit vents blocked with insulation. These things block attic ventilation which allows the warm, moist house air that has migrated into the attic to condense on the underside of the roof sheathing. Seal the ceiling openings to reduce the amount of warm, moist air from migrating from the house into the attic. Add a vapor barrier on the attic floor, below the insulation.

Idea 2:
Your roof slope looks shallow. Some shingle manufacturers recommend a waterproof shingle underlayment for roof pitches between 2:12 and 4:12 pitches. The shingles are less effective for shedding water atshallow roof slopes.

Have you checked what the relative humidity in the attic is?

The humidity is probably 0 right now, but I'll check it tomorrow as its suppose to be hot again. This cold/hot/cold/hot weather is getting really annoying. I can't wait for this winter to be over with. I'm counting down the months. Less than 2 left!

So I went up on the roof today, there's 2-5 feet depending on the area. I shoveled what I could, but I was getting brutally tired, I'm really out of shape apparently. I mostly skimmed it as I did not want to rub against the shingles too much. I left a couple inches of snow on it. The snow was very crusty. The vent where it was leaking had a ton of ice all around it. Maybe 3-4 inches of it. It was almost like a big bowl of ice. I was unable to break that off so I'll have to monitor the situation tomorrow. I also have a roofer coming out to check out the situation.


The top vent was clear of snow as it's right at the peak and there was not as much snow there for some reason. The soffit vents are possibly blocked, if there's even any. I have a feeling it's just plywood. I'll definitely check that in summer, and I'll also install some baffles. I cannot physically get to the eves from inside the attic but I may be able to install the baffles from outside. I also think I need more insulation up there, so I'll probably get it blown, much easier than crawling in there with one piece of fiberglass at a time.

But all in all, I'll just wait and see what the roofer says. My hunch is the venting and lack of insulation. The pitch is also not helping, maybe the shingles used were not meant for that pitch.

Funny thing is now that I have all this extra snow against the house it will be a problem this summer when it melts as I also have bad weeping tiles. One problem after the other it seems.

Your insurance will cover the damage done by the riif leaking.

You have a lot of snow that you should be getting off from the roof

You need to get a snow rake and keep that quantity off your roof.

your problem is most likely from snow getting into the vents and from the ice dams.

Very hot today, and no leaks, so shoveling the snow helped. I also went back up today and was able to dislodge the ice dam and get a bit more snow off, though now the snow is wet and heavy but the worse of it is already off at least. The ice dam at the leak was a good 60lbs of ice at least. I had trouble pushing it down.

I had a roofer come over and he told me what I expected, the venting is bad. So he'll give me a quote on fixing that, as well as adding blown insulation. There's also a spot where there's flashing that's not there, it's not so much a leak issue given the location, but best to get that fixed too. Might actually be where the mouse got in this winter. I also told him he can remove that vent completely, I barely use it anyway. This roofer and others I've talked to said vents for stuff like that are usually bad and best to avoid them as much as possible. Vent through the soffit if you have to.

I was thinking of doing some of the work myself, but think when it comes to a roof, I'll leave it to the pros. Damn I'll be spending lot of cash this summer it looks. Still need to get the weeping tiles done too.

Amazing how heavy snow can get huh. That freezing, thawing, freezing, more snow on top etc.. can really add a lot of weight fast. Glad to hear you are getting it under control.

So far no leaks and it's still very hot out. It's +10C. Crazy to get tshirt and jeans weather at this time of year.

Tomorrow will be the real test though, it's suppose to rain. Yuck. Roads are going to be nasty.

Remember that snow pile?

Well it's all melted now! It's been insanely hot for this time of year. I'm surprised my basement is not leaking. Seems the snow is evaporating rather than melting.

That said, I just got the quote to do the work.

- Remove/replace soffit to cut out vent openings. That also includes taking down the gutters putting them back.
- Installing baffles in the attic.
- Blow 4" cellulose insulation in both attics (is 4" enough? what is the R value of that insulation?)
- Cancel microwave vent on the roof.
- Cleanup

$1200 + HST

Install vent on garage (not related, but thought I'd throw that in while they're there)
$200 + HST

-Remove/replace shingles and siding on one section of roof to fix flashing, not leaking there, but it's an area that could leak and possibly how mice got in.

$475 + HST

I also asked to do the venting in the upper attic while they're there, quickly he figured about $300 extra but he'll let me know.

Overall I'm looking at under 3k to do all that so while I could do lot of that myself, it seems like the type of project that is more of a hassle than fun, so I'll leave it to the pros and since I never done any of that stuff before at least I'll know it's done right. I guess it's kinda against the spirit of DIY.
