New Roof Installed Questions/Problems
I had a new roof installed about 1 month ago, the day the roof was installed it was about 90+ degrees. There are numerous 10-15 areas the the top part of the shingle is scuffed or damaged from walking on. The contractor told me the crew should have not been working on with it being that hot. The contractor said it would not cause no problems and you can't really notice but said he would come back out and replace the damage ones individually. Do you think this is a good idea or would it be better to leave well enough alone?

Second questions, in a couple areas the shingles look wavy inside of smooth like the rest of the roof, what could cause this? I was told that they will lay down eventually but we have had 90+ temp 3 weeks since the install.

Thanks for any help.

When a storm rolls thru and knocks down tree limbs that strike/scrape your roof or other parts of your home you have damage.

Or you have a hail storm that drops hail stones on your roof you have damage.

Or you have high velocity winds that slings debris thru the air and it strikes your home you have damage.

Who do you contact first?,,,,Your insurance provider.,,,and why?? because of damage.Not necessarily instant destruction but future accelerated damage due to things striking your roof.

That is why your insurer pays for hail damage.It is what happens to the shingles/materials over time.

Same thing with tracked/gouged or scuffed up.If a shingles surface is compromised by this activity then that portion of the shingle is weak.In time it will start an accelerated process of breaking down.

You paid for a new roof.You did not pay for a scuffed up roof that now has some weak areas.Have them replace the areas that are damaged.

The wave issue could be several things.,.,if possible post some pix.

Attached is two pictures of damage to shingles from working on roof when too hot (per the contractor) do you feel these should be changed out? Also does it hurt in anyway of changing out individual shingles? Also when they break the tar seal to replace a shingle will it bond again?
I could not get a picture of the wavy/hump part of the roof so you could see, one thing about that part of roof it is behind a tree and only gets a very little direct sun, could this just take longer to set.

It is relatively simple to swap them.It is in your best interest to have them replaced.

The contractor is coming out to replace the damaged shingles later this week, one last question. On the buckled/wavey shingle I couldn't get a picture to show it but in several places the shingle or shingles or buckled or raised up. You push down on them and I have even tried to hold them down a minute or two and they pop or buckle right back up. What could it be, contractor told me before they would set down with warm weather and it has been over a month and 90+ degree everyday and still have not set down. Just trying to be prepared for contractor. To me, it is above the nailing spot or below, it seems like they are too tight. Any thoughts would be greatly appreciated. Thanks

I am in no way insulting either your or the contractors intelligence but have them replace the entire shingle.It is quite obvious but sometimes you never know.

Once again not try to insult anyone but I would be home when the repair is taking place.That way you know for certain and the contractor is for certain that the shingles removed are the ones you wish to have replaced.

Once again its obvious but important for both the installer and the homeowner to be on the same page.Not sense in prolonging the issue by another call back.It would be a waste of your time as well as the installer's.

As far as the wavy shingles is concerned w/o pix one could only speculate.

Several things could cause what you are seeing and touching.

1.Since the temps were hot its possible to have improper air pressure set and the nails are blowing thru the shingles.Depending on the size of the installer(weight) the shingles could have been walked out.

Meaning when the shingle is installed and with the fastener blowing thru.Then with nothing really holding the shingle in place it could have slipped out of place just a bit under his weight.The result could be the shingle is now contorted and has sealed that way.

2.The shingle in fact wasn't butted properly and is too tight.

3.The felt has a bubble in it.If felt is not rolled nice and flat or has been exposed to moisture it will have a air pocket.Whether it be rain,morning dew and has not be allowed to dry prior to installation that can contribute to the shingle appearing raised.

4.Rolling felt over raised nail heads from the previous roof.Rolling felt over protrusions will give the shingles the raised look.

5.Rolling felt over debris.Loose nails shingle particles,damaged H-clips etc. should be completely removed during deck prep work prior to felt installation.Not cleaning the deck and rolling over debris will give the shingle a raised look.

6.Decking fastener popping.Sometimes the decking can pop out.During deck prep work the decking should be inspected to make sure all the decking is fastened properly.If any part of your decking isn't fastened properly the shingles will not lay flat giving the raised look.

7.Roofing over warped decking.If the decking isn't as flat as possible and is split,busted or bowed it will give the shingle the raised look.

8.Improper deck replacement.I have seen laminate flooring,coffee cans,license plates,shingle tabs/backs paneling,flashing you name it being used over bad decking.(Knot holes,split and rotted decking etc) Installing shingles over these items can cause the shingle to have a raised look.

If you are present during the repair ask the installer to find out why they are laying the way they are.
