How to Choose Roofing Materials and Install Properly
Whether you're planning to hire a contractor or tackle a roof repair yourself, understanding what you're working with makes all the difference. We've walked through enough roofing projects to know which questions matter and which are just surface-level details. This guide pulls together what we've learned about evaluating options and understanding the installation process, so you can make decisions confidently rather than just following what someone else recommends.
The Problem, Stated
A new roof is one of the bigger home investments, and the industry makes it harder than it needs to be. Material names sound interchangeable (asphalt, composite, architectural shingles?), installation methods vary by climate and pitch, and most manufacturers' specs assume you already know roofing terminology. You can end up choosing based on what looks good at the supplier or what your neighbor did, rather than on what actually makes sense for your house. The right material is the one that matches your climate, your budget, and your willingness to maintain it over time.
The Options Compared
| Material | Lifespan | Cost Range | Maintenance | Best For |
|---|---|---|---|---|
| Asphalt shingles | 15–20 years | $150–300/sq | Low; occasional cleaning | Budget-conscious, mild climates |
| Architectural shingles | 20–30 years | $250–450/sq | Low; occasional inspection | Better durability, moderate cost |
| Metal roofing | 40–70 years | $400–800/sq | Low; sealant inspection every 5 years | Long term, snow load, hail |
| Wood shakes | 25–40 years | $600–1000/sq | High; regular cleaning and treatment | Character, mild climates only |
| Slate | 50–100+ years | $1000–1500/sq | Very low; mostly structural | Historic homes, permanent installation |
| "Sq" means 100 square feet; labor and flashing typically cost $50–200/sq additional. Climate (freeze-thaw cycles, hail, wind, sun exposure) can cut lifespan by 30–50% from the manufacturer claim. | ||||
Questions to Ask Before Committing
What is the roof pitch on my house, and does it matter?
Pitch (the slope angle) affects water runoff and which materials you can install. Anything under 4:12 (4 inches rise per 12 inches horizontal run) needs a membrane roof or specialty materials—standard shingles won't shed water fast enough. Steeper pitches (8:12 and up) shed water naturally and are compatible with everything from asphalt to slate. Most residential roofs are 5:12 to 8:12, which gives you good options without special precautions.
How much will the old roof disposal cost, and who handles it?
Tear-off and disposal can add $1–3 per square foot to your total bill. Some materials (like slate or clay tile) cost significantly more to remove. Get your contractor to specify whether the tearoff is included in their quote or bid separately. If you're doing a repair or overlay instead of full replacement, disposal is either zero or very small—confirm that upfront.
Am I choosing the material or the contractor, and which really matters more?
Both matter, but the contractor matters more if you're installing. A quality install of a mid-range material outperforms a poor install of premium shingles every time. The flashing (where the roof meets walls, valleys, and vents) is where 80% of leaks happen—and that's all installation. Read reviews of local contractors and call references before you choose. Then talk to them about material options rather than deciding material first.
What warranty am I really getting, and what does it actually cover?
Manufacturer warranties on shingles typically cover material defects but not labor or water damage from installation failure. Contractor warranties (the real protection) vary wildly—get one in writing. Most reputable roofers offer 5–10 year warranties on their work alone, separate from the shingle manufacturer's 25–50 year coverage. Ask what "workmanship warranty" means to them before you hire.
What to Consider First
The actual installation process changes by material, but the groundwork is always the same. You need a clear picture of your roof's current condition, your climate's demands, and your timeline. Get at least three quotes from licensed, insured contractors—not to find the cheapest price, but to understand why prices vary. A contractor who gives you a detailed breakdown of what's included (shingle grade, flashing material, tear-off method, warranty details) is already ahead of one who just quotes a total. Look for someone willing to explain their choices rather than just execute yours.
Step Through It
Once you've selected your material and contractor, the install itself follows a consistent sequence regardless of shingle type. Understanding what happens at each stage helps you recognize quality work when you see it, and it frames the conversation if something looks off. The crew will start with a full tear-off of the old material to expose the roof deck. They'll inspect the deck for rot or damage and replace any soft wood before they lay a single new shingle. The drip edge goes on next—that's the flashing that directs water to the gutters and away from your fascia. Ice and water shield covers the lower edges and valleys (the places most prone to ice-dam leaks). Then comes the underlayment, a breathable but water-resistant layer that handles any water that gets past the shingles. Only then do the shingles themselves go down, with starter shingles at the eaves and each course nailed or stapled according to the manufacturer's pattern. Valleys get sealed, vents get flashed, and the ridge cap (the shingles that cover the peak) gets sealed with roofing cement. The final step is cleanup—a quality roofer walks the perimeter with a magnet to pick up every nail and scrap.
Next Steps
Start by getting your roof inspected if you haven't recently—a licensed inspector will tell you whether you need a full replacement or just repairs, which changes your timeline and budget dramatically. Then get three quotes from contractors, making sure they're breaking down material choice, tear-off cost, and warranty details separately. Read the fine print on the manufacturer's warranty, and confirm that your contractor's workmanship warranty covers their portion. If you're leaning toward doing any of this work yourself, take a materials-focused class or workshop first—roofing isn't forgiving of mistakes, and a $500 class beats a $5000 fix later. Once you decide, commit to maintenance: clean gutters twice a year, clear moss or algae growth, and inspect after major storms. A roof that gets maintained lasts 20–30% longer than one that doesn't.
