Complete Guide to Rolled Asphalt Roofing Installation: 1 Minute to a Durable Roof: Fast-Track Guide to Rolled Asphalt Installation

Rolled asphalt roofing, also known as roll roofing, is a cost-effective and practical option for covering low-slope roofs and smaller structures like sheds or garages. Unlike traditional shingles, rolled asphalt roofing comes in large rolls, making the installation process quicker and more straightforward. In this guide, I’ll walk you through everything you need to know about rolled asphalt roofing installation—from preparing your roof, essential materials needed, step-by-step instructions, and the key considerations to ensure a durable and watertight finish.

Step 1: Preparation

Begin by thoroughly cleaning your roof’s surface, removing all debris, nails, and any existing roofing materials. Inspect for rot or damage and repair as needed. For the best results, the roof surface should be dry, clean, and as smooth as possible; this ensures better adhesion and longevity of the rolled asphalt material.

Step 2: Gathering Materials

1. Rolls of asphalt roofing
2. Utility knife or roofing cutter
3. Roofing nails and hammer
4. Roofing cement
5. Measuring tape and chalk line
6. Roofing primer (if required by product)
7. Protective gloves and eyewear

Step 3: Installation Process

1. Lay down the underlayment: Depending on your local climate and building codes, install roofing felt or a vapor barrier over the surface first. This adds an extra layer of protection against moisture.
2. Measure and cut the roll: Starting at the lowest point of the roof, unroll your asphalt roofing and cut it to the appropriate length, allowing for a slight overhang at the edges for drip protection.
3. Apply roofing cement: Spread a thin layer of roofing cement along the bottom edge to help secure the first roll and prevent wind uplift.
4. Roll out and fasten: Roll out the asphalt roofing across the roof, nailing it at regular 6-inch intervals along the edges and every 12 inches in the field. Overlap each succeeding roll by at least 4 inches and seal the seams with roofing cement.
5. Finish edges and seams: Pay extra attention to sealing edges, ridges, and overlaps with cement to prevent water infiltration. Trim excess material neatly for a clean finish.

Step 4: Final Checks and Maintenance

Once installation is complete, carefully inspect for any gaps or loose edges and reinforce them with additional cement. Over time, periodically check your rolled asphalt roofing for signs of wear, tears, or pooling water, and address any issues promptly to prolong its service life.

As a designer, I see roofing not just as protection, but also as a key element in the overall aesthetic and functionality of a space. If you’re already considering upgrades or redoing your roofing, you might find digital visualization tools helpful for planning your next big home improvement. You can create a detailed roof or exterior plan using intuitive

3D floor planner solutions, which offer precise modeling and visualization for all your home or outdoor design projects. This approach can save you time, reduce costly mistakes, and ensure your roofing installation complements the entire structure’s design vision.

Tips 1:

Always install rolled asphalt roofing during fair weather. Moisture trapped during installation can lead to premature failure. Also, for steep-slope roofs, rolled asphalt isn’t suitable; stick to flat or gently sloped surfaces only.

FAQ

Q: How long does rolled asphalt roofing last?

A: Typically, rolled asphalt roofing lasts 5–10 years, depending on climate, maintenance, and installation quality.

Q: Can rolled asphalt roofing be installed over shingles?

A: It is technically possible, but not generally recommended due to potential moisture and adhesion issues. Always check local building codes.

Q: Is rolled asphalt roofing waterproof?

A: Yes, when installed correctly with careful sealing, rolled asphalt roofing provides a waterproof barrier for low-slope roofs.

Q: What are the main advantages of rolled asphalt roofing?

A: It’s budget-friendly, relatively easy to install, and a practical option for outbuildings or temporary structures.

Q: When should rolled asphalt roofing be replaced?

A: Replace when you see significant cracking, curling, extensive leaks, or bald spots where the surface material has worn away.
