Rot-Proof Trim

If you're tired of replacing wood trim, porch posts, or fencing that keeps rotting, there are now alternatives that hold up to weather without losing the look of traditional woodwork. Companies make fiber-reinforced polymer columns, PVC trim boards, and engineered porch planks that can be cut and shaped like lumber, then painted so they're hard to tell apart from real wood once installed. Brands mentioned include AZEK and WindsorOne, which make engineered beadboard for porch ceilings, Aeratis, which offers PVC beaded-board ceilings and planking, Fiberon, a wood-plastic composite decking made for covered porches, and the Gingerbread Man, which makes decorative brackets from an engineered hardwood composite called Extira that resists splitting better than solid wood. If you want to keep real wood but reduce future rot, some shops will custom-mill trim from rot-resistant species like Port Orford cedar.

For homeowners dealing with rotted rafter tails rather than trim, a repair called a Dutchman patch can fix the damage without removing the roof. It involves cutting out the decayed wood, shaping a new wood patch to fit the opening, treating the old wood with fungicide, and gluing the patch in with waterproof wood epoxy before sanding it smooth and repainting. If the rafter ends carry structural weight, the roofline gets temporarily braced with lumber during the repair. This is a targeted fix for isolated rot rather than a full replacement, which can save both the wood and the look of an older roofline.
