Are you supposed to remove the plastic strip on shingles?
Once shingles are installed, the cellophane strips no longer align with the adhesive, and the cellophane does not have to be removed. In fact, it should not be removed because it often carries printed information about the shingles.
How do you measure shingles to keep them straight?
The first line you lay is the most important to keeping the installation straight. Lay the line, check it, and then recheck it several times. To check the line you will want to measure from the bottom of the shingles to the line. The distance from each measurement should be the same.
When laying out three tab shingles how much shorter should the starter tab be?
Ensure they are positioned with the factory-applied sealant strip face up and the strip adjacent to the eave edge of roof. Cut 6″ (152 mm) off one end of the first starter shingle and lay it on a lower corner of the roof, overhanging the rake and eave edges by ¬º”- ¬æ” (6 -19 mm).
What do you put down on a roof before shingles?
Underlayment— This is the first layer of waterproofing that goes down in between sheathing and shingles. Underlayment seals the roof from damaging elements like snow, ice and rain. Also referred to as a membrane, underlayment is mandatory for providing the roof with a waterproof barrier.
Does anyone use 3-tab shingles anymore?
This article is not saying 3-tab shingles are a bad roofing material. It’s just important to know they’re being phased out of the industry, and the preferred asphalt roofing choice is now architectural shingles.

How many nails do I need for 3 tab shingles?
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. Drive nails straight so that nail head is flush with, but not cutting into shingle surface.
What happens if you nail shingles too high?
When the shingle is nailed too high the nail does not penetrate the shingle below it. High nailed roofs are easily blown off in windy or stormy conditions because the roof isn’t ‚Äúconnected‚Äù like it should be. Inadequate nailing means big reduction in wind rating.
Can you over nail a shingle?
If you drive even one nail into the top of your roof, you may compromise its entire system.

When it rains, water can enter the hole, bypass every layer of security on your roof and trickle into your attic.

Can you put shingles on backwards?
Some roofers simply take regular shingles, flip them upside down and nail them down as a starter course. The problem with this approach is that it doesn’t allow for proper adhesion between the starter course and the first layer of shingles.
