What I'm Seeing Now

Don't Nail Through The Shingles!

This could not be simpler - don't nail through the shingles!

On a new construction, pre-drywall inspection, I saw something that I see so often.

The siding guys anchored their scaffolding by driving nails through the shingles.

What usually happens is they then "fill" the holes later with caulking or tar.

On this house there were 8 such support arms nailed to the roof.  That is a minimum of 16 nail holes.

They did this on my house 19 years ago and my supervisor assured me the holes would be filled and would never leak.  Of course they did.

Nailing through shingles exposes holes forever.  No caulking or roof tar lasts forever.

The shingles here are new and very pliable.

They can be easily lifted to secure a roof support arm underneath.

Once the job is done the holes can THEN be filled with tar and the shingle laid back down.

This way the holes are permanently filled and protected, and the tar will never let water in.

My recommendation:  it's the little stuff that makes big differences!  If builders, and subcontractors, pay attention to the little things, it's my experience that that big things will take care of themselves.  Care is the first part of the word careful.  There are many small reasons to be careful with how things are built.  Products and craftsmanship can last a long time if done right!

Good morning Jay. You don't have to be a contractor or inspector to know this is really stupid.

I feel that way about satellite dishes too... they just run lag bolts right through the shingle tabs!

Wow, now I never thought of that - great suggestion Jay Markanich and one I will be passing on next time I see someone about to nail into a shingle!

I completely agree that small things turn into larger things when not dealt with over time.

Sheila - holes are good in golf and cheese.  Not in roofs?

Fred - they don't have much choice, but they CAN choose to include that semi-permanent rubber seal under the anchor plate!

Jennifer - I have had a couple of these such posts.  Some things, and ideas, are good to recycle.

They do Harry!  Here the contractor would argue that the nails don't go into the house.  Well, wood rot is wood rot.

Thanks for the great advice Jay Markanich . 30 years ago when I put TV antennas up for people we really had no choice with the interlocking shingles but to put lag screws through them and tar the heck out of it.

Good morning Jay! You know, I have seen that and thought... hmmm... that looks like a problem. And now I know it really is! 

Lay-zee?

Excellent tip Jay Markanich - I just saw a neighbor get themselves a new satellite dish and yep, nailed ontop of the shingles!

It is just crazy the number of times we have this issue noted on inspection reports, Jay Markanich 

Posted by Sandy Padula and Norm Padula, JD, GRI, Presence, Persistence & Perseverance (HomeSmart Realty West & Geneva Financial, Llc.) almost 3 years ago

Bob - the fix for that would be to replace the shingle when the antenna is removed.  And not a hard one!

Andrea - a hole is a hole!  Why complicate a job with unnecessary attachments!?

Jessie - those are other culprits seen all the time.  Usually those are installed up the roof somewhat so the holes are into the attic!

S&N - with good reason!  It got noted on this report too!

Thank you Stephen.  It's good to get info out there, and one of the reasons I come to AR is to acquire info!
