Question DetailsAsked on 10/7/2013

A tarp was stapled to my asphalt shingled roof. The tarp was removed but the staples remain. Will that cause a leak

This roof is one year old. A contractor stapled a tarp to the roof to prevent water damage to a balcony that he was constructing. The staples appear to be flush with the shingles.

Possibly but unlikely. It depends on the size and length of the staples. If he used short staples that didn't penetrate both layers of roofing you should be fine. However, he has likely compromised the integrity of the shingles. It's hard to say whether it will cause problems or not without seeing it. Personally, I'd err on the side of caution and replace those shingles or at least apply sealant under the tabs where there are staple holes. Make sure the staples didn't penetrate all the way through. If they did, replace the roofing in that area.

I guess I am a little less conservative than Todd on this one - unless you are compulsive about your roof appearance, I would just take a pair of diagonal cutters and tube of bitumastic roof caulk and go up on the roof, carefully pry out (using a scrap of plywood wood as a pry surface to avoid crushing the shingles) with pliers or diagonal cutters any remaining staples or pieces of staples, then caulk the holes. If you cannot grab the staples because they are down into the shingle, two alternatives - lift the center of it a bit so you can grab it with the pliers by prying it up with a small tip screwdriver prying against your piece of wood, or just caulk completely over the staple to reduce rust staining and, many years down the road, the possibility it will rust through and leave holes for water.

When caulking the holes, use a smallish hole opening in the tube (about 1/8" - just big enough you can squeeze the caulk out without excessive effort), and hold the tip down tight to the shingle while squeezing the caulk into the hole so it penetrates, and does not spread out all over the shingle in an unsightly blob. If you are reasonably careful, it will just make small black blobs that should not be at all noticeable from below.

You could have the contractor do this (he should have done so), but unless you are afraid of roofs I would do it yourself so you are sure it is done gently and does not crush or tear shingles. If you DO decide to have the contractor do it, I would tell him you want the staples carefully driven flush if they stickk up, then bitumastic caulk over them rather than pull them - a lot less chance of roof damage that way.
