Ask roofers to cut back shingles extension from 1 to ?


Should I? All rakes and eaves have D style drip edge. Certainteed says beyond drip edge is ideal and that shingles must not extend farther than at most.

Almost everyplace on our house, the extension is about 1 which local roofers think is really good. The roof was installed last winter.

The roofers say (1) the shingles would look bad by now if they were ever going to, so not to worry and (2) the fact that a starter course was used will keep rake shingles from drooping and (3) that 1 provides better protection from capillary action.

Has anyone had personal experience of problems with 1 extensions?

Thanks.

They should be installed by manufacturers specs. An 1 1/2" overhang will sag and look like bad...and most likely lose some longevity, especially in a hot climate like SC. Too much of an overhang could also be susceptible to wind uplift and damage.

And yes I am a certified Certainteed shingle installer.

I would not install a 1&1/2" overhang but now that it has been like that for 1 year. I would leave it as is. The risk of cutting the entire rake edge of the home is not worth the reward of reducing the overhang.

The two plausible concerns for too much overhang are: 1) Wind Uplift 2) Drooping shingle overhang.

Wind Uplift would result in shingles blowing off your roof.

Drooping overhang would result in an aesthetic issue - not functional.

SDC and Roof Diagnostics, thanks for your replies. SDC, do you know what RoofDiagnostics would have meant by the "risk of cutting the entire rake edge"? Is it that it would look messy because, at some points, they'd be cutting through 3 layers of shingle? We have Landmark architectural asphalt shingles.

In my opinion and per Certainteed, It is done wrong....period. If you do have any wind related blow offs, I would doubt it would be covered by Certainteed.
How much damage will it cause.....probably none.

You have many answers on two different threads...it is up to you what you would like to do with it.

It could easily be cut back on the gables, either a cordless circular saw (yes I have done this on an angled roof to keep the overhang consistent)on a colder day (keeps it from getting gummed up) or snips will work. On the eaves it may be a little harder, if you cut a half inch to an inch, you may lose the adhesive strip from the starter coarse.

I hope this helps.

BTW why after a year is this concerning you now? Is there an issue?

My thoughts exactly.

Sophia, to be clear - i agree that the overhang is wrong.

My differing is with the recommended action, i do not believe it is "worth it" - having the contractor cut the shingles back.

I wouldn't worry about overhang at the eaves(if you have a gutter)It is the norm in my area,but 1 1/2 on the rakes is a fugly.

Ask roofers to cut back shingles extension from 1 to ?


Why I'm asking these questions now: It's been an ongoing house renovation. They're going to do gutters next; and this brought up questions about what we want regarding gutters and downspouts; which caused me to notice details of that roofing area more closely. I noticed and wondered about a couple of things and then started researching and here we are. We love the new shingles themselves and knew nothing about proper roofing practices and trusted the roofers to do the details competently.

Why so many separate threads: Just was thinking it would be a good idea, for clarity, to separate out my questions into separate threads. Maybe I should have just done one thread called Sophie's Questions? In fact, I'm about to start another thread called something like Water and Ice Not Needed in the South? because yesterday I saw a photograph taken during the roofing process in which there is tar paper all the way down to an eave and I'm thinking there would not be water and ice under the tar paper.

Thanks for your interest and help.

Not always. This situation is often what happens when the homeowner tries to be a contractor and hires a bunch of seperate subs. The quality control usually suffers.

Federer, I didn't mind at all--I have started a lot of threads. MJW, that's not our situation: all the same contractor.

Thanks, everybody, for your contributions to my education.
