My new roof seems to not be rodent-proof


I just got my roof replaced with Timberline Ultra HD shingles with ridge vents a month ago. The other day I went up the roof to check whether the new roof is sealed tight (against rodents), I found that between the two roofs meet, there are gigantic gaps where even a big rat can go through and then into my ridge vent slits.

I quickly spray-foamed the openings for the time-being. (I know those spray-foam is not going to last very long due to UV breaking them down.)

I do not have rats in my attic nor crawl space yet but I am being very paranoid about those stuffs. I cut down a few tall trees surrounding my house just for that purpose. But rats are pretty smart and they can climb up my stucco wall. Thus I will make sure that I do not have any entry points anywhere into my house.

Attached are the photos I shot. The foam and the shiny metal mesh were added by me just a few days ago for temporary defense against possible rodent intrusion. I am very worried that possible rats/squirrels will enter through these big openings or through the gaps between the ridge vent and the shingles. (Shouldn't those places be tight?)

It is tight under those cap and you're wasting your time worrying about it.

For one thing those ridge vents never should have been run that far up into the valley area. I leave them back about a ft. on each end of any roof line.
That style valley should have been compressed where it meets at the top so the caps would have laid flater.
Correct me if I'm wrong but those look like just reguler shingle caps not the thicker rip and ridge type that's made for 30 year shingles.
Why are they all sticking up like that?
It looks like the caps on the left were run in the wrong direction. The top part of the cap should have been laided so it came out under the ones along the main roof. The way they installed them water running down one roof is funneled under the caps.
Keep in mind all we have to look at is pictures I'm not there looking at it in person.

I didn't like the 'layout' either. Those are 2-part caps thought.

As Joe mentioned, we only have pictures, but although I agree that the some of the techniques look different to me, as for your primary concern, I agree with Tinner, in that I do not see anything that is of concern in regard to pest infiltration.

1. Less chance of scarring/cutting through the under shingle.
2. As clean a valley line as cutting it with snips, but easier and quicker.
3. No need to cut/clip ears, or run a bead of caulking underneath.

I do it simply because it's easier.

So you don't run a pre-made starter shingle up the valley and cut to that?

That looks like a real mess. First, like said earlier, the ridge vent should not be run that close to the valley. Second, it looks like the ridge shingles that are installed closest to the valley have some mesh under them. I don't think I would be as worried about pest infiltration, as I would about water infiltration. Call the roofer to come back and replace those shingles and change the ridge vent. Plus, it's UGLY

Sorry for going off topic, i should know better.

I agree with some of the comments here and disagree with some others, but the best advice I seen posted thus far was suggesting you contact the roofer/s who installed the roof and have them come back an inspect their work and answer your questions/concerns.

Most likly the roofers are going to say it looks fine.
My next call or at least an email with pictures would be to the company that made the shingles. If your lucky they may even send a rep out to look at it. If they did I'd bet there not willing to warrenty that roof the way it was done.
Even the vent company after taking one look at it would aslo tell you that.

If you don't mind me asking joe, are you a roofer, or some one who has roofing experience?

I have thought about making that switch, still not sure if I want to do it.

It took me a long time to make the change from weaved valley's to closed cut valley's because I was suspicious of it's quality at first.
I had the same feelings about switching to the bleeder method.
So far I have found nothing to make me think either system is of a lesser quality then weaving.
