Shingle roofing weather question NEW QUESTION - 10/20/20 02:07 AM

Hello. Today and tomorrow our house is getting shingled. Cloudy and temp in the 40's both days. Weds cloudy and chance of rain. Thursday mostly sunny, 80, but 20-30 mph wind, we live on a hill and the south wind will be hitting the roof full on. Not sure about the pitch but it is relatively steep. I am hoping the shingles can seal Thursday AM from the sun before the wind really picks up. Just wondering what your thoughts are? Nothing can be done about it now and I am not paying until after Thursday. 40 year Malarkey shingles that get 6 nails per shingle. Can't change the weather just wondering if anyone has any thoughts about how the shingles may fair. Thanks for your thoughts.
NEW QUESTION
Roofing crew finished today and it looks good. When I got a bid from one company one of their selling points was the ice dam barrier in all valleys and above the gutters. When I talked to the sales guy of the company I went with they only did it in the valleys. I asked if they could do it above the gutters. He said yes. Our house pitch is kind of steep, we live in NW MO, and the house is cape cod type with no overhang so it probably doesn't need it but I thought it sounded good and was part of the deal. I confirmed it with him 3 other times with Sat being the most recent. Yesterday I told the site manager (that came and went) and he said he would tell the crew chief. This AM I asked the crew chief about it (hard to understand) and it sound like it may or may not have got done. This afternoon I checked and if it is supposed to be sitting on top of the gutter apron it is not there but is in the valleys. I will bring it up to the sales guy before I pay. QUESTION: What would you do? Job was $9500. Money off and amount? Thank you for your time.

Best place to watch weather is WINDY.COM
especially for weather further out.

We built our house in 2004. Put 50 year landmark shingles on in December. The contractor said he would heat them so they would glue down. He didn't do it and said they would stick the next summer when it got warm. I called bs and he said he would check them every year for 5 years. Never saw him again and started losing shingles after about 5 years. Put tin on two years ago and couldn't be happier.

The new sealant on shingles will adhere with a sunny 30 degree day.

Roofing this time of the year is always a risk. Last one I helped on was late like this and our only saving grace was a low pitched roof and an early snow to hold them down. Still had a few we had to glue down but still a pain. If I could do it over I would have talked them into a steel roof.

It also keeps those stray #5 shot from making holes !!

I study roof failure for a living. 1) I am not a fan of roofing in cold weather but the most problems I see are with 3 tab in subdivisions. 2) Your Markley should be superior to those shingles and will hopefully partially seal on the day they are installed (and be ok in the wind) and then fully seal when they get that 80 degrees.

Keep us posted I am curious

I've installed thousands of squares of shingles in all types of weather. I did a barn roof in January one year and had to wait three weeks for the snow and ice to melt off the north side before we could finish.

My roofs are warrantied for two years against defects in workmanship. If shingles blow off or leak because of something my company did, we fix it for free. I've never had a call-back and I've been doing this a long time.

As long as there is a competent crew installing them, your shingles will be fine.

most blown off shingles come from being nailed on wrong

Agreed. Acquaintance of mine went for the weekend discount shingling job, 2 yrs later shingles were coming loose in small sections. Turned out the shingles were nailed from above with the installer facing down the slope creating an angling and cutting issue with the shingles.

Re: Shingle roofing weather question - 10/20/20 12:27 PM

Sometimes you have no choice but to nail from above. The asphalt in light colored shingles will bleed through and show footprints if walked on during a hot day. We have often had to nail from above. You just have to make sure your guns are perpendicular to the roof and your air pressure is properly adjusted.

But yeah, I've torn off a lot of shingles that were not nailed properly. That is usually the first thing an insurance adjuster looks at.

Just another good reason to avoid light coloured shingles!

I won't pretend to have the experience some here have, but anyone that says it can't happen and they'll be fine sounds like a salesman. I had a roof done in mid October, with several 70 degree days shortly after. Some strong winds came through a couple weeks later and tore off a section where the winds hit it. Some shingles were sealed and some weren't, the installation was done correctly. Unless they're sealing each one individually, there is a risk they could blow loose.

Re: Shingle roofing weather question - 10/20/20 01:55 PM

If your shingles blow off.
They were installed wrong, nailed above where they should be
Or you got junk shingles
I've installed shingles down to -20f. Never a call back on any roof I've ever installed
Pride in ones work seems to be a thing of the past

Like I said, you sound like a used car salesman. Or worse to be honest, because you're clearly lying. I have no doubt you've never had a call back, but to say it can't happen, or to just blame it on poor install or bad shingles means you're FOS. It CAN happen in certain situations. The situations aren't common or even likely, but any honest person would never say never.

I've been installing and replacing shingles for 30 years.
How long have you been doing it?

Where on this thread did anyone say "It can't happen?" Of course it could happen. High winds tear shingles off houses all the time.

Two top quality, professional roofers gave their experiences related to roofing in cold weather and how over the decades it has never once been a problem for either one of them.

And here you are calling one of them out over something that was never said.

Maybe you're the one who is FOS?

I started with metal roofing after loosing many shingles in a hurricane in Florida... I was very happy with it and swore it would be the only thing I ever used from that time forward.

After moving back to Ohio, my second year back... we had a good storm accompanied with 60+ mph winds... Lost considerable number of shingles... Had the whole roof redone and again used metal.
I am still elated with metal and have shown many others, their fears about metal are uncalled for. Of course good craftmanship in any work, is a must. The metal was less expensive than than the better shingles.

Shingles on my shed leaking, dang metric junk grin
I too am converting to metal as I upgrade.
Another has slate, cant understand it, they only xxx years old lol.

Had a home owner once INSIST I remove that cellophane on the nail stripe,
so they stick.
I told him no way, throw me off job or go call O-Corning.
He hired me a lot afterwards, and trusted my judgement.

Edit, I've saw more installer damage in hot weather than cold.

And sometimes you cant nail where you want because of seams in wood.
Those laminated jobs come to mind there.

No idea how important it is in your area but here at least one and ideally two courses of ice and water shield is a must with our weather conditions.

Re: Shingle roofing weather question - 10/21/20 12:49 AM

Here in PA it is in most local building codes that ice and water shield be installed in the valleys and the first course (36") of the eaves.

Re: Shingle roofing weather question - 10/21/20 01:30 AM

Ice n water shield should be a non issue in a modern built/insulated home.

Re: Shingle roofing weather question - 10/21/20 11:52 AM

Turkey time
I would have them prove the ice and water shield is installed, otherwise they better discount the job
here in the east its code to have it installed at gutter line. we can get a lot of ice damming
the valleys need flashing anyway so ide be surprised if they were not done.
ive been selling roofing for 36 yrs

Re: Shingle roofing weather question - 10/21/20 04:18 PM

I don’t know about your state but when I was roofing it was code to have ice and water a foot minimum past exterior wall and inspector had to verify it either from pictures or on site.
We did plenty of roofs in the cold and never have had a callback, like stated earlier a lot of blow offs is from improper nailing.

If you didn't get it in writing in your proposal/contract you might have a problem. Talk is cheap!
