Roof underlayment usually lasts as long as the roofing material that covers it, as it’s not directly exposed to the elements. In most cases, roofing companies will replace the underlayment each time they install a new roof. In some cases, particularly with slate, clay, or certain metal roofs that can last 50 to 100 years, your underlayment may require replacement within that timeframe, especially if you start to notice roof leaks.

In most cases, it is best to leave icicles on your roof and allow them to melt naturally. You should only consider removing them if they are heavy enough to cause damage to your home or pose a risk to people below. Since removing icicles can be dangerous, it is recommended to hire a professional for the job if you have immediate concerns. To prevent the issue from recurring, you should address the underlying cause, such as improving your home's insulation or installing roof heating coils.

If you see rust spots or streaks or any physical damage to the chimney cap from the ground, you should hire a professional to inspect and replace it. If it’s safe to get up on your roof or near your chimney cap with a ladder, you can perform a closer inspection to identify issues. Additionally, if you know your chimney cap is nearing the end of its life—usually five to ten years—or you’re seeing evidence of water damage or pest infestation in your chimney, it’s a good idea to replace the cap.

Yes, installing snow guards is highly recommended for metal roofs, especially if you live in an area with moderate to heavy snowfall. Metal roofs have smooth, slick surfaces that offer little traction, which can cause large, heavy loads of snow and ice to slide off all at once in a dangerous "rooftop avalanche."

This sudden release of snow can cause serious injury to anyone below and damage personal property, such as cars or landscaping.

Snow guards act as a barrier, holding the snow on the roof so it can melt and slide off in smaller, more controlled amounts. While low-slope metal roofs in areas with very little snow might not strictly require them, installing snow guards is a valuable safety measure to protect your family and property.
