There are two sides to winterizing your roof for winter: one is preparing the exterior of your roof, which involves repairing shingle damage, making sure your gutters are clear, and thinking about how to divert snow drifts. But inspecting your roof's interior is just as important because it can give you important insight into future damage to watch for and developing problems you can fix now.
Unless you have an attic window, you want as little sunlight as possible shining in your attic. If you do, it's a sign that you have small gaps and holes that lead straight to the outside. Not only does that mean your heated air will be replaced with a chilly breeze, but also those gaps will let water leak inside and invite winter pests looking for a warm place to stay. While you want to check over all the nooks and crannies of your roof's interior for damaged caulk and worn sealant, inspecting for sunlight is a good place to start.
If you don't inspect your attic, you won't know about potential water damage until it reaches your ceilings, and that results a much larger repair bill. Check for moisture, darkened insulation, and ringed splotches on the wooden joists. These hint at small but long-term leaks.
The most important thing about your insulation is to make sure you have it. There should be insulation lining the inside of your roof, both in between the joists and foamed along any flashing and vents. But just having it isn't a sign that insulation is doing its job completely. Also look for gaps where it has fallen away from contact with the roof, darkened blemishes of moisture and mildew, and compressed spots where the insulation won't work as effectively. Replace the batts or foam where you see signs of damage, and make sure the insulation rating is up to best stand against your area’s winter climate.
Inspecting the interior of your roof gives you crucial insight into two main winterization problems: how tightly sealed your roof is against water, drafts, and pasts, and how well the insulation can keep your home warm.
