How many nails do you put in a 3-tab shingle?
NAILING: Use galvanized (zinc coated) roofing nails, 11 or 12 gauge, with at least 3/8″ diameter heads, long enough to penetrate through plywood or 3/4″ into boards. Use 4 nails per shingle placed 6-1/8″ above the butt edge, 1″ and 13″ in from each end and 1/2″ above each cutout.
How do you install shingles over existing roof?
Can I put new shingles over old shingles?
The answer is yes, you can lay new roof shingles over old ones. You can‘t do it with wood or slate, for example, and you should never mix materials, such as laying asphalt shingles over cedar shakes. Also, the old roofing has to be in pretty good condition.
Should old shingles be removed?
While a repair job can often be more convenient and somewhat more cost-efficient, placing new shingles over old ones is never a good idea. Whether repairing one section of roof, or a replacing a whole one, it’s always best to pull up the old shingles before putting down the new ones.
Can you put underlayment over existing shingles?
Installation is easier than for a tear-off job because you can use the existing shingles as guides for laying the new ones. Some roofers install a layer of waterproof shingle underlayment (WSU) over the existing shingles at the eave end, as would be done for a roof laid on bare sheathing.
Can you put a second layer of shingles over architectural shingles?
Yes you can install a second layer of shingles over the existing layer of shingles. I would recommend that you remove any step flashing or vents and pipe stacks to make sure that they have no damage from previous installation.
Can you put plywood over old shingles?
The new plywood will have to be nailed to the rafters or roof trusses. But, with the old plywood left in place, it will be considerably more difficult to locate the rafters to ensure proper nail placement.
Does flashing go over or under shingles?
Instead of installing the step flashing between shingles, the flashing rests on top of the shingles. It’s not unusual to see sealant installed when sidewall flashing is missing. Sealant will eventually dry, shrink and break. You’ll see sealant substituted for flashing in a lot of different areas on roofs.
How do you install roof flashing under shingles?
How do you seal shingles to drip edge?
You can hand-seal the rake shingles down to the drip edge or use a double-sided roofing tape. Shingles along rake edges are vulnerable to being blown off in high winds. Often the nails alone won’t hold the shingles fast to the roof.
Do roofers replace flashing?
Flashing should be installed underneath new shingles to prevent water damage. Roofers sometimes poorly install flashing over the shingles instead of underneath, which compromises their water resistance.
How much does it cost to install roof flashing?
Generally, the cost of fixing flashing is anywhere between $15 to $25 per linear foot, which includes both the price of the new flashing itself and the caulking used to seal it in place (which is about $10 on its own or sometimes more). A total flashing replacement might cost anywhere between $300 to $600.
What to look for after a new roof is installed?
Check to see if the area is clean
Any good contractor knows that they need to clean up once they’ve completed the job. A simple walk around the premises will reveal if they’ve actually cleaned up. You should look for nails or debris, especially if an old roof was torn down before installing a new one.
Is flashing included in roofing?

Should roof flashing be caulked?
Some flashings are built into products like a bathroom vent roof cap or the standard plumbing vent pipe flashing. It’s okay to use caulk and roofing cement as a last resort to make a temporary leak repair, but don’t allow a roofer to convince you they’ll work for the long term.
