Do I have to redo asphalt shingles if they weren't layered underneath?
Question:I just had a guy come out today who says he knew roofing. I only paid him $40 and I bought the shingles, but he didnt use roofing cement and only hammered "roofing" tacks into the shingles. These are asphalt shingles. The rest of the roof has them layered with half the shingle under the one on top. With his repair job he didnt layer them, but placed the shingle in line under the one above it.
When I asked him, he told me that if he lifted the shingles above, he would have to glue or tack those down and then the ones above them and so on like a domino effect. I wonder if he was just trying to get out of bringing roofing cement up on the roof. I saw those containers at Home (ripoff) Depot and they are only sold in those huge 5 gallon containers.
Do I have to buy the materials and do this myself? Or is this going to be ok? The roofing tacks are exposed on those shinges. Is that going to be a problem?
Answers:
The shingles must be layered. Period. Otherwise, they will leak when it rains. You do not need roof cement for the new shingles. They have a strip of cement already applied.
You do need roof cement where the new shingles are placed under the old ones. Yes it is possible, and no you do not have to take loose shingles other than the layer immediately above the repair.
For what it is worth, roof cement comes in 5 gallon, gallon, quarts and caulking tubes.
Honestly, you got about what you paid for. Perhaps this guy was trying to help you out, maybe he was looking for a quick buck. Either way, you need to find someone that has a clue before it rains.
First of all, you don't have to use glue or cement.
But the shingles "MUST" be layered. The ones closest to the bottom edge are on bottom, the next row goes on top, and the next row on top of those and so on.
This does not sound good to me. I would have someone to look at it.
Yeah, they should be layered.
This is a huge problem for someone that dosent live in lets say Phoenix Arizona where it never rains. But if you have to deal with any precipitation at all I would consider hiring someone else to do the job. He was lazy and was underpaid. It would have cost you a couple hundred to get your roof repaired by a professional, with guaranteed results or your money back! He was supposed to use cement and layer the shingles. If the tacks are visible then he did a very poor job, the are penetrations in your roof and if it rains will leak directly through the shingles into the plywood and eventually causing much more severe damage. To avoid a huge pitfall later I would suggest paying the money now to have it fixed right! Good Luck!
The guy was a hack. Get it fixed right.
