Pittsburgh winters dump heavy wet snow that piles up fast on older roofs. I see rafters from the 1950s and 60s in Squirrel Hill and Regent Square crack right at the mid-span when the load hits 30 pounds per square foot. We sister new 2x8s alongside the old ones using construction adhesive and structural screws, then add collar ties every four feet to stop further spread.
Cheap crews often just slap on new shingles without touching the structure. That leaves the roof sagging worse the next storm. Allegheny County requires a permit once you open more than 100 square feet of decking on a repair like this, and inspectors check the new bracing before they sign off.
Point Breeze and East Liberty homes with original 2x6 rafters at 24-inch centers fail first during a March thaw when snow turns to ice. We pull the old felt, check every rafter with a level, and sister only the damaged ones instead of tearing the whole roof. That keeps the job under four days in most cases.
Winter Snow Load Prevention
Check your attic after every storm that drops more than eight inches. Look for new cracks in the ceiling drywall or doors that start sticking. If you see either, call before the next freeze cycle makes the wood brittle.
