What are the Materials Needed for Roofing a House?
When you hear the word “roof,” shingles may be the first thing that comes to mind—but a reliable roofing system is much more than just the top layer. Every roof is built from several components that work together to protect your home from the elements, control temperature and moisture, and support long-term structural integrity. If you’re wondering what goes into the process, here’s a breakdown of the essential materials needed for roofing a house:
1. Roof Decking
Also called sheathing, this is the foundation of your roof. Roof decking is typically made from plywood or oriented strand board (OSB) and is attached to the framing of your home. It provides a stable, flat surface for the roofing system and serves as the anchor for fasteners, underlayment, and shingles. If the decking is rotted or damaged, it must be replaced before any new materials are installed.
2. Underlayment
Installed directly on top of the decking, the underlayment is a moisture barrier made of felt or synthetic material. Its primary role is to prevent water from seeping into the wood decking and attic space. In climates like New Jersey’s—with humid summers, rain, and possible snow accumulation—high-quality underlayment is a critical line of defense against leaks and mold.
3. Drip Edge
This narrow strip of metal flashing is installed along the roof’s eaves and rake edges. It helps direct water into the gutters rather than allowing it to seep behind fascia boards or siding. Drip edge flashing also protects the underlying wood and helps prevent rot, especially during heavy rain.
4. Ice and Water Shield
This is a self-sealing, rubberized membrane that provides additional protection in vulnerable areas such as roof valleys, chimneys, skylights, and eaves. It’s designed to stop water from ice dams and wind-driven rain from penetrating beneath shingles and causing internal water damage.
5. Shingles or Other Roofing Material
The visible outer layer of the roof, shingles are what most people notice first. In New Jersey, asphalt shingles are by far the most popular because of their affordability and durability. However, depending on the architectural style and budget, homeowners may also opt for metal, slate, wood, or synthetic roofing materials. Each comes with its own benefits and lifespan.
6. Flashing
Flashing consists of thin sheets of metal, usually aluminum or galvanized steel, that are installed in places where the roof meets vertical surfaces like chimneys, dormers, and vent pipes. Flashing helps seal joints and prevent water from entering through cracks and seams. Without properly installed flashing, even a brand-new roof can develop leaks.
7. Ventilation Components
A well-ventilated roof improves energy efficiency and extends the lifespan of your roofing system. Components like ridge vents, soffit vents, gable vents, and attic fans work together to move hot, moist air out of the attic and bring cooler air in. This helps prevent mold, ice dam formation, and premature shingle deterioration.
8. Fasteners and Adhesives
These include roofing nails, screws, and specialized adhesives that hold each component in place. Using the correct fasteners ensures the roof can withstand strong winds, heavy snow, and fluctuating temperatures. Professional roofers use corrosion-resistant fasteners that match the roofing material for long-lasting results.
9. Starter Shingles and Ridge Caps
Starter shingles are the first layer installed along the roof edges. They provide a secure foundation for the first row of main shingles, preventing wind uplift and leaks. Ridge cap shingles are placed along the peak of the roof to seal the ridgeline while enhancing ventilation and giving the roof a finished appearance.
How Do Roofers Use These Materials?
Roofers don’t choose materials at random. Each piece serves a purpose. Furthermore, roofers select materials based on their experience, manufacturer guidelines, and preferences. Here are some factors that help roofers decide on the best materials for roofing your house:
- Weather Conditions: Roofers prioritize materials that can withstand South Jersey’s seasonal changes, including high winds, heavy rain, and snow.
- Roof Pitch and Design: Some roofing materials work better on steep-sloped roofs, while others are designed for low-slope or flat roofing applications. For example, if you roof is a blend of flat and sloped, your roofer may suggest a membrane that works alongside shingles rather than against.
- Budget and Longevity: Contractors will offer material options based on cost, durability, and warranty coverage.
- Energy Efficiency: In warmer months, reflective or cool-roof materials can help reduce attic temperatures and cut energy bills.
- Aesthetic Appeal: Homeowners often want roofing that complements their exterior, which influences color and texture choices.
Roofing Materials FAQ
Can I choose different materials for different parts of my roof?
Yes, in some cases. It depends on the materials needed for roofing a house like yours. For example, homeowners may choose architectural shingles for the main roof but use metal or rubber in low-slope areas.
Is it cheaper to do the roof myself?
Initially, it might seem more affordable, but DIY roofing often leads to expensive repairs due to improper installation, lack of permits, or using the wrong materials.
How long do roofing materials last?
Most asphalt shingles last 20–30 years, while metal and slate can last 40–75 years. Longevity depends heavily on installation quality and maintenance.
Do all roofing materials come with warranties?
Yes, but warranties vary. Some cover just the materials, while others (often through certified contractors like RGB Construction) include workmanship as well.
