Questions to AskTo a non-roofer, learning about roofing systems in your spare time and on the weekends is a tough sell. We get it. But when you’re making a large investment in your roof, it pays to know what you’re actually paying for. Many homeowners don’t take the time to learn roofing system essentials, or they rely on their roofing contractor to fill in the blanks. The problem is, many contractors aren’t forthcoming with that information. Whether it takes too much time, or whether they don’t want you to know what they’re doing, it differs on a case-by-case basis. When you have a new roof installed, you need to make sure it will last for years to come. Many people just ask for a bid, get their bid, and think a shingle is a shingle. They leave it at that. A new roof is a big investment, so we want you to know about the entire roofing system, and what each part entails. That way, you’ll know what to ask your contractor. Don’t worry, though, because it won’t take long at all.
The Anatomy of a Steep-Slope Roofing SystemIf you have a steep-slope roof, there are at least three parts of your roof you need to know about:
- Roof Deck - The deck is the underlying structural foundation that supports the roof, usually referred to by roofers as a substrate. Generally, your decking is made from plywood, oriented strand board, or other wood-based materials.
- Underlayment - The underlayment creates another weatherproof barrier between your home and the elements, and provides protection for your roof deck and the home underneath. You might not ever see it, but it’s important, even in our relatively snow-free climate.
- Roof covering - Your shingles.
When it comes time to install a new roof or fix up the old one, you need to see your roof as a system. Each interlocking part serves its purpose, and your shingles need a good deck, solid underlayment, ventilation, and other little touches to live up to their full potential. Take it from a roofing company, South San Francisco has plenty of steep-slope roofs. We want to make sure homeowners get everything they can from their roofing systems, and know the right questions to ask their contractor. ~Mr. Roofing San Francisco’s residential & commercial roofing experts
