I have architectural shingles. The shingles have separated
into two pieces. Can you please tell me what's going on?
When you nail an
architectural shingle, there is a small area about 3/4" of an inch wide
where the shingles are supposed to be nailed. It is very easy to miss this
area. Chances are, that's what happened. There will be a nail line showing
where the nails are to be placed. Nails should not vary more than 1/4" from
This doesn't mean that the sealant hasn't failed, but most likely it's
improper fastening which is almost certain what the manufacturer will tell
you if you turn in a complaint about it.
I want to use staples instead of nails to install my shingles. Is this
No. Never use
staples to install asphalt shingles.
One contractor says a nail gun is better and another says hand nailing is
better. Which is the preferred method?
Hand nailing allows
better control and is the way to go. However, it's usually more affordable
to use a gun because hand nailing is more labor intensive. If a gun is used,
the pressure should be regulated to keep from damaging the shingle by
overdriving the nails. Some guns have built-in pressure regulators, and some
don't. Typically, the tank pressure should not exceed 90 psi; the gun will
have the recommendation on it.
