Traditionally, roofing season runs from spring through the fall, but some contractors decide to keep the work going year-round. Roofing in the winter has its challenges and requires careful planning and precautions for keeping your crews and materials functional and safe.
Pros of winter roofing
Stop heat leaks
For anyone who has ever opened a shockingly huge heating bill, you know how costly heat leaks can be. Heat rises and will escape through any cracks or gaps in your roofing. Repairing these leaks will not only protect you from water damage, but also save you money during the winter.
Most roofing crews assume that work will slow or stop completely during the winter. As a result, some roofers offer off season prices to keep their crews working during the winter. They also tend to have more open schedules than they do during the warm season, so booking jobs can be more straightforward.
Winter roofing precautions
Timing construction projects during the winter can be tricky. Roofing crews need to work fast to make the most of shorter daylight hours and take advantage of any dry weather spells. Typically, this requires more hands-on deck in order to churn out tasks in a matter of hours instead of days.
Ice and snow removal
Removing snow and ice from a roof can be a very dangerous endeavor. However sometimes emergency repairs cannot be postponed until springtime. Before any roof inspections can be conducted prior to a roofing job, snow and ice must be removed. Use a professional roof clearing service to ensure it is removed safely. Some ice melt chemicals damage roofing materials, so be sure to use ice removal products that are designed for roofs.
Warm your adhesives
Most roofing materials require adhesives that need warm weather (or an artificial heat source) to cure and fasten. During the warmer months, radiation from the sun would soften the adhesive, allowing it to seal the shingles together properly. Colder than 70° F and the glue stays too viscous, leading to weathering and erosion. Installing a roof in the winter, without the proper precautions, will lead it to fail quickly, if not immediately.
When solar radiation is weak, like during winter months, alternative heating sources are needed to keep adhesives warm and workable. Bulk material warmers, bucket warmers, and barrel heating jackets can be applied to adhesive containers to keep their viscosity low and your productivity high.
Bundle your shingles
Keeping your shingles bundled and warm protects them up until they are ready to install. Under extreme cold, most materials become brittle and harder to work with. Make sure to follow the manufacturers stacking instructions so they are stored properly to avoid breakage.
Protect your tools
As temperatures drop, pressure-controlled tools lose functionality. Nail guns and air compressors cannot achieve the pressure needed to reach velocity. Storing your hoses and compressors in a warm environment will increase their usability and help you work faster during dry periods. Warm storage also prevents ice from building up inside your hose lines. Switching to a lighter winter grade oil during will also help your compression tools work more efficiently during cold weather.
Watch your nails
Under driving nails during the winter can be a real problem. Ice buildup and frozen adhesives can impede proper nail driving. Under-performing compressors also cannot generate the force necessary for nails to penetrate. Warming your tools, shingles and adhesives will help ensure your nails are properly driven and that the roof is secure.
Be aware of warranties
Some roofing materials have strict temperature requirements when used under cold weather conditions. For example, most asphalt shingle manufacturers require that a specialized adhesive be applied by hand to each shingle for temperatures below 40° Fahrenheit (4° Celsius). The manufacturer will void any warranty if the specialized adhesive is not used during shingle applications below 40° F. Cold climates not only effect the adhesive, but also cause the actual shingles to become less flexible and are more likely to break if dropped.
EPDM (rubber) membrane roofing is even more sensitive to its environment than asphalt shingles. Like a composition roof, EPDM requires warm temperatures to soften the adhesive needed for curing. Even at high temperatures EPDM can be difficult to work with because it is so thick. As a result, manufacturers recommend it be higher than 45° Fahrenheit (7° Celsius) to install EPDM. When external temperatures fall below this mark, warm storage areas are necessary in order to keep the adhesive pliable until it is used.
Think inside the box
Roofing materials come in a wide variety of container shapes and sizes. How do you keep stacks of shingles, and drums, or barrels of adhesive warm all at the same time? Electric pallet warmers can be a very versatile warming option for materials of all shapes and sizes.
