From the thatch atop a cottage to lashed boughs that form a lean-to, simple roofs are testament to the fact that humans have been building shelters for a long time. But when you think of a typical roof on today’s average building, what does it consist of? How does it work? As any roofer can tell you, the workings atop the structures we live and work in are often taken for granted until they stop functioning properly. Read on for a few common components of roofing systems, many not visible to the naked eye.
- Rafters: For peaked roofs, rafters form the framework that gives the roof its structure. They extend from the ridge (highest point) to the eaves (where the roof meets the walls of the building).
- Decking: Decking forms the roof’s base, supporting any subsequent insulation, waterproofing, and outermost weatherproofing material like shingles, etc. Obviously, it’s important that the decking be able to structurally hold everything atop it—it’s usually plywood or oriented strand board.
- Underlayment: Underlayment is installed between the topmost layer and the decking for additional protection from moisture. It’s typically asphalt-saturated felt but can be other materials as well.
- Gutters: All roofs need a system to direct water away and off the surface to prevent rot and water damage. Whether K-style, half-round, or even an inner piping system, no roofing system is complete without drainage.
And these are just the basics of roofing systems! As you can see, they are composed of many elements working together to keep you comfortable and dry. It’s no small feat to keep roofing systems in order. Even if your roof isn’t displaying obvious damage, it’s wise to schedule routine maintenance to ensure everything is in good shape.
