Shingle Roofing in Cold Weather - Can you Replace a Roof in the Winter? - IKO

Contrary to popular belief, cold weather does not necessarily signal the end to

roofing season. If you've been hired for a repair or installation during the

winter, you'll find a number of resources on our blog about fall prevention and

how to prepare a safe work surface. This video will specifically cover the extra

precautions that will need to be made during preparation, product handling and

installation. Be forewarned, it's going to take a little more care than you're used

to. First thing to note is that asphalt

shingles behave differently in cold weather. As temperatures approach

freezing, standard asphalt shingles will become brittle and more prone to

breakage. Some roofers preferred polymer modified shingles, which tend to be more

flexible in most temperature ranges - however, at some point, cold weather

affects even these. As well, if the bundles have been improperly

protected from recent precipitation, you may face the headache of bundles

freezing together. To prevent these issues, store them properly, preferably in

temperatures higher than 10 degrees Celsius or 50 degrees Fahrenheit.

We recommend storing them off the ground, stacked flat - to ensure they don't deform.

Lastly, place a waterproof cover over them for further protection. When it's

time retrieve your shingles only just before you need them; do not keep them

exposed to the outside elements for longer than you have to. When it comes to

hip and ridge caps installations, this minimum temperature may not cut it.

Luckily IKO offers a line of pre-formed, precut ridge cap shingles that require

no cutting or folding. Naturally snow and ice will also need to

be dealt with before even attempting work. Exercise extra caution if

conditions are slippery from melting ice and snow. Regardless of the season, the

attic cavity should be properly ventilated before you begin. It's no fun

to work in the winter, but sometimes it's completely necessary. Work carefully and

expect the job to take longer than it would have in the warmer seasons. Another

step to remember - depending on the home's location, you may need an ice and water

protector when applying your underlayment. These special products are

applied under shingles to prevent water penetration due to ice dance or wind-

driven rain. In addition to protection along the eaves, it is useful when

creating a watertight seal around chimneys, vents stacks and other roof-top

structures. When you begin securing the shingles, just like every other part of

the process, this too comes with extra special

precautions. Normally, IKO's shingle adhesive is heat-activated by the sun, so

it may not occur until the roof experiences sufficient warm sunlight. But

rest assured, there's a way to prevent them from blowing off. After placing each

shingle, nail it down with six nails, instead of the regular four. Once in

place, gently lift the edge and apply three evenly-spaced, quarter-sized spots

of roofing cement. It's also important to remember some proper handling techniques

for nail guns. There's a good chance it could seize in the cold weather and

there's an even better chance that you can blow through the cold shingles -

especially if they are not laying perfectly flat on the roof deck. Adjust

the pressure on your nail gun accordingly to bypass this common

pitfall. Always follow your shingles manufacturer's instructions for cold

weather application, paying close attention to your region's building codes.

It's a tough job, but someone's got to do it just. Remember that above all, to never

put your work before personal safety. Finishing a job isn't worth risking a

life, so please be sure to respect the limits mother nature may impose while

abiding by proper industry safety requirements. We hope this video has been

helpful to you. If you're looking to learn more from the experts at IKO,
