Temporary Roof Protection

[sparky67]

Timing is not working out as I would like. We are just finishing the foundation work now and the cold weather has arrived. I'm going to continue with framing but I'm wondering what I should do with the roof. This garage is attached to the house and part of the project is to add dormers to the house. I'd like to have the roofing done all at once but at this point it is not a nice time of year to be opening up my house roof for the dormers. That means I will probably be waiting about three months. Should I just put 30# felt on the garage roof for now or is there something better I would be using in this case? Will it keep the inside sufficiently dry for insulation and sheetrock?

I believe 30# felt will work,however you have to staple it,so now you have holes for water to find

Those blue tarps from Harbor Freight might help.

Ice and water shield would be more water proof;however it cost quite a bit more than 30# felt. I believe the felt will allow for some water leakage.

30# felt with the tin tabs to keep it from blowing off will keep the sheathing dry enough to prevent damage. But It won't keep all water out especially if it snows and you get ice dams. I wouldn't finish the inside until the roof is on.

If it's not a large area, you could ice and water shield the whole thing. That would keep it dry until you got a roof on, but it's expensive.

felt paper will tear in a wind, I would use tarps and nail furring strips every 24" or so. as others have said Ice & water will work well too.

The felt paper today is not what it once was. If you expect it to last 3 months, you will back up on the roof at least once re-nailing it after it shrinks and tears.

We've used this as a temporary covering.

We call it tarp on a roll. Literally impossible to rip the stuff. It's sold to be a permanent underlayment, but I wouldn't recommend using it for that.

x3 on ice and water shield. Mine went through a winter and spring with nothing on it but ice and water shield. Our area almost beat a 100+ year old record for consecutive days of snow on the ground that year. Not a drop of water penetrated the roof. My intention was to use it on 100% of the roof regardless of my bad timing with weather.

Choices:

30# felt will need furring strips as noted, will leak less than you would think,

and will stand well against wind if you will also strip the showing horizontal

edges as well as vertically on 2' centers. Also will be the cheapest. We

did this all the time with excellent results.

Blue roof (tarp) will hold up OK for one or two windy rain storms, then will

start to become iffy and will start to tear and lose resistance to water

intrusion. If we had a storm coming over the weekend, we would use a

tarp with good results. Absolutely the cheapest of coverings in time and

money spent for a short haul solution.

Ice shield will be the last word in water and wind resistance, but will

hurt in the pocket book. Will not need furring strips or any other hold-

down hardware as it is self adhering to any and everything including itself !

If I were going to have a year w/o a top shingle, I would think about

using the stuff, and taking the time to apply it correctly. For a garage

and a 3 month wait, I would opt for felt with hold down strips and not worry

about a small amount of water seepage.

There you have it...pay yer nickle, take yer choice !

Ice and water shield for 2 years before shingles for me on shop addition, found a few craigslist deals on left over roofing supplies to reduce cost.

There is an old house near where I live that has a layer of tar paper over top the shingles. No strips, just stapled down.

The house is best described as "bulldozer bait", and evidently not worth re-roofing.

I'm assuming the owner is waiting for the right offer from a developer, though it's had the tar paper for several years now.

Ice and Water Shield works very well. That is what I used on my garage roof and I shingled over it when done. Mine was only about a month though. I would recommend you use Grace or another GOOD brand. The off brands do not stick as good or seal as good. It does stick down but it needs some sun and heat so you do have to nail or staple it. But is seals around them well. For three months I would probably use the button nails. Grip Rite makes some. You can also cover the whole thing with a tarp to keep the sun from damaging the Ice and Water shield.

As for the money, I was using the Ice and Water shield anyway for the first two course and my garage is 24x28 so it was only the matter of buying an extra roll for about $110 at the time. I think they are like $130 for the bigger rolls now.

Good luck.

What about roll roofing, i.e. asphalt shingle roll. It should go down fast, be semi-permanent, tear it off when you get ready to do the whole roof.
