How warm does it have to be to put shingles on a roof?
According to Roofing Construction & Estimating By Daniel Benn Atcheson, the best temperatures to install asphalt shingles is between 40 and 85 degrees F (4 and 26 degrees C). If you’re installing roofing shingles in cold weather below these temperatures your shingles may become brittle and more prone to breakage.
Do you need a starter strip for shingles?
The starter strip is crucial because it adheres to the shingles on the edges of your roof and protects them from the elements. Without starter strip shingles, a gust of wind would have no trouble sneaking under the shingles on the edges of your roof and blowing them up, and perhaps even off, your roof.
Is it better to hand nail shingles?
While air gun nailing might seem faster, a well-trained hand nailer can do it almost as fast. The key difference between the two is accuracy. Hand driving nails into shingles allows for the roofer to place the nail on the proper nail line and then drive the nail in.
How many nails do you need for shingles?
General Guidelines for Nailing Shingles Install the recommended number of nails per shingle. For Duration® Series shingles, Owens Corning recommends using either a 4- or 6-nail fastening pattern depending on the roof’s slope and building code requirements. In most cases, 4 nails are adequate.
What underlayment to use for shingles?
What Is Roofing Underlayment? Roofing underlayment is what lies between the shingles and the roof sheathing, or roof deck, which is typically either plywood or OSB. It’s installed directly on the roof deck and provides a secondary layer of protection from the elements, including rain, snow, and wind.
How do you install missing roof shingles?

How long does it take for shingles to adhere?
It usually only takes one or two warm days for that to occur. But overcast weather conditions, cold weather, snow cover, or shingles installed on the north slope of a roof can go an entire winter without warming up enough to stick together.
How long does it take for roof shingles to settle?
Time and Other Considerations Curing time for the tile adhesive seal depends on the manufacturer and should be taken into consideration when selecting the season for installation. In general, ceiling tiles take 48 hours to cure after activation of the strips.
What do roofers do in the winter?
Roofers might be willing to work on the roof in the winter, but their tools might not. Some tools like compressors and nail guns might be rendered ineffective or even unuseable by the freezing temperatures. Roofers will need to give extra effort to make sure their work is of good quality.
Does a roof need a drip edge?
Without a drip edge, water may end up beneath the shingles and may cause damage to various parts of the home. Though your home may not have originally had a drip edge installed, drip edges are now required by most building codes across North America to protect homes from damage.
Should shingles overhang the drip edge?
Asphalt shingles should overhang the exterior edge of the drip edge by ¼ to ¾-inch. Check local building code for drip edge requirements prior to the start of your roofing project.
Why do you put the first row of shingles upside down?
The sealant on an upside-down three-tab shingle ends up far too high up the roof to effectively seal the first course of the finished shingles. The proper way to adapt three tabs as starters is to trim the tabs off the shingle along a line across the tops of the cutouts.
Is it OK to lay shingles in the rain?
Never lay roof shingles when it is raining When it starts to rain during the roof installation, it is always recommended to stop the installation and to temporary cover the roof. During a rain shower the roof also becomes slippery, which can cause dangerous conditions for the roofer.
Can I use a nail gun for shingles?
Shingles should be mechanically fastened with a pneumatic nail gun if the contractor determines that the roof sheathing is consistent and free from gaps. Most roof systems with plywood or OSB sheathing will fall into this category.
Can you use a nail gun for roof shingles?
Roofing manufacturers have determined that hand-nailing shingles and using a nail gun are both valid methods of installing shingles, so it is not a reflection on your roofer’s work quality level if they choose one over the other.
Can I use screws for roof shingles?
You cannot use screws for roofing shingles, only roofing nails are approved fasteners. Screws leave small gaps in the material they are driven into, and this may be enough to allow for a leak.
Can roofing nails be too long?
Yes, they can. If they are too long, they will protrude through the sheathing at the roof overhang and be visible.
How far should shingles hang over roof edge?
Shingles should be installed over the drip edge a minimum of 3/8” (9 mm) at both the eave edge and the rake edge. If the drip edge extends… out from the rakes and eaves (typically called DL Style or D Type), the shingles may be installed flush with the drip edge.
Should I put ice and water shield on my entire roof?
Potentially, covering an entire roof with ice and water protector can prevent leaks even after high wind conditions blow shingles off the roof—preventing further damage and making repair easier.
