A new roof is a must when there are signs of damage to the current one. An obvious sign is leakage, which often shows up on the ceiling in the form of stains, discoloration, or bulges. But there are other indications that may only be visible upon close visual inspection atop the building. These include damaged or missing shingles, loss of asphalt shingle granules, and rusted flashing.
Replacement roofing material can differ from state to state and even from one company to the next. When it's time to re-roof a house, homeowners living in cold climates need to keep the following considerations in mind.
Keep Energy Costs Down
On cold days, a great deal of heat can escape if a roof was not installed correctly or the proper materials weren't used. A quality installation with the right materials will keep heat inside the home, where it belongs, thus keeping energy costs down. Roofing that is sized properly, well-sealed, and energy efficient will perform better in extreme weather. A contractor experienced in cold-weather designs and installations will be able to assist with making the right choices for any budget.
Avoid Snow Accumulation and Ice Buildup
Blizzards can be brutal in terms of how much snow accumulates on top of a house, as well as where ice buildup can occur. Sloped designs can remove snow and ice more effectively. Flat designs, however, don't work well because the snow will pile up, and the weight can cause damage. When the snow starts to melt, the puddles that form can also cause damage.
Which materials perform best in winter weather? Metal does a good job of shedding snow quickly, but care must be taken. For example, having a large pile of snow or ice suddenly slide off near a door or any spot where somebody might be standing could be a dangerous situation. An experienced roofer can inspect the premises and offer advice regarding the best course of action. Metal roofs offer other advantages, including durability and less likelihood of springing a leak.
Asphalt shingles also hold up well in winter weather. Asphalt is a good insulator, and the light, flexible shingles can support a significant amount of frozen precipitation. Slate tiles are another good option. Slate is strong, durable, and holds up to both packed snow and springtime hail.
Winter Is a Challenging Season for Roofing
A roof can be a dangerous, slippery place in winter. Ice is a serious consideration. Workers, tools, and materials can also easily fall off during inclement weather.
In addition, the quality of the end result will be compromised if roofing material is installed in snowy, wet conditions. Adhesives may freeze upon application, and frozen shingles may snap when hammered. For these and other reasons, manufacturers provide recommended temperatures for installation. It's important to adhere to these recommendations.
Roofing can be completed successfully in winter on dry, warmer days. It's prudent to check with the contractors to see what they recommend and to follow their guidelines for the best results possible. Waiting a month or two is worth it for the sake of safety and a superior installation job.
