When it comes to your roof, you may think it’s all about the shingles, flashing and gutters but not true! Soffits and fascia boards are two of the most important components of your roof.
The planks fitted to the underside of your home’s overhanging eaves are called soffits and most often, they’re constructed of vinyl and contain small openings that allow your attic to breathe. Stagnant heat and moisture can wreak havoc on attics and roofs so soffits ventilate the attic and prevent your rafters from rotting.
Fascia serves a different but important role in preventing roof and attic damage due to moisture. Fascia boards are fitted over the end of your home’s rafters or trusses and serve as a barrier between your roofline and the elements — making your home comfortable, safe and condensation-free.
Soffits cycle heat and moisture out of the attic, keeping your home warmer in the winter and cooler in the summer. This ventilation system and the protective barriers provided by fascia boards help to correct the air circulation in your home, specifically the attic — where heat and moisture can lead to condensation and ultimately mould. Condensation in an attic is often misdiagnosed by homeowners as a roof leak but it’s actually much worse. It can lead to a host of issues including ineffective insulation, damage to rafters and trusses and ice damming which can lead to interior water damage. Whether in the form of leaks or condensation, water can result in thousands of dollars’ worth of damage to your home.
In the winter months, snow and rain will ultimately lead to moisture buildup in your home unless you take steps to prevent it. Without protection, this moisture penetration will result in mould, which will lead to rotting in your rafters and sheathing. Soffits and fascia fortify water entry points, thereby preventing damage to the frame of the house. By failing to keep moisture, mould and rot at bay, homeowners may face irreparable structural damage.
While they add value in terms of protection, soffits and fascia also add value by giving your home a clean appearance that can greatly improve curb appeal as well as reducing your energy bills by allowing your home’s airflow to operate more efficiently. The long-term benefits of lower utility costs far outweigh any up-front investment.
