What is asphalt shingle roofing?
An asphalt shingle roof uses fiberglass-reinforced shingles coated with asphalt and mineral granules, installed in overlapping courses over a prepared deck, underlayment, leak barriers, starter strips, flashing, and ventilation components.
Most sloped single-family homes, additions, garages, and homeowners who want broad color choices, familiar maintenance, and a competitive installed cost.
Potential advantages
- Strong value for most residential budgets
- Large selection of colors, profiles, and warranty levels
- Widely available repair materials and trained installers
- Works on many common New Jersey home styles
Tradeoffs to evaluate
- Shorter potential lifespan than slate or many metal systems
- Granules and seal strips can be affected by heat, wind, foot traffic, and age
- Dark attic conditions and poor ventilation can accelerate wear
- Not suitable for sections below the manufacturer’s minimum slope
Expected lifespan and what changes it
Many architectural asphalt roofs provide approximately 25 to 35 years of service when correctly installed and ventilated. Exposure, roof pitch, attic heat, tree cover, maintenance, and product grade can shorten or extend that range.
Published warranty periods and real-world service life are not the same thing. A roof can age early when intake ventilation is blocked, exhaust is unbalanced, flashing is reused, nails are misplaced, decks move, drainage concentrates water, or tree debris remains on the roof. A lower-priced system installed carefully can outperform a premium product installed without proper details.
How it performs in New Jersey
Cold winters and humid summers make deck preparation, ice protection, ventilation, and proper nail placement especially important. Wind ratings matter in exposed areas, while algae-resistant granules can help on shaded north-facing slopes.
Terra Nova serves Bergen, Passaic, Essex, Morris, Union, Sussex, Somerset, Middlesex, Monmouth, Mercer, Hunterdon, and Warren counties. Exposure changes across these areas—from wooded inland properties and higher-snow locations to dense neighborhoods and coastal-influenced conditions—so the final system should be selected after evaluating the actual home.
Installation details that influence performance
- A clean, sound, properly fastened roof deck with damaged areas documented and replaced as needed
- Underlayment and self-adhered leak barriers selected for slope, code, manufacturer instructions, and vulnerable transitions
- New or serviceable flashing at sidewalls, chimneys, valleys, skylights, plumbing vents, and roof-to-wall intersections
- Starter materials, edge metal, fastener type, nail placement, and course layout completed to the product requirements
- Balanced intake and exhaust ventilation based on attic design rather than simply adding more roof vents
- Gutters, downspouts, valleys, and discharge points arranged to move water away from the roof and foundation
- Final cleanup, magnet sweep, photographs, product records, warranty documents, and a clear workmanship warranty
What affects the installed cost?
Roofing cost cannot be determined accurately from material price alone. The roof’s measured area, pitch, height, number of layers, access, tear-off, deck repairs, valleys, dormers, chimneys, skylights, ventilation, edge details, disposal, permits, labor skill, warranty level, and protection requirements all influence the final scope.
- Roof size, pitch, height, number of sections, and complexity
- Tear-off quantity, deck condition, and concealed repair allowances
- Material grade, accessory system, flashing, ventilation, and warranty requirements
- Property access, landscaping protection, parking, staging, and debris handling
- Season, delivery logistics, permit requirements, and specialty fabrication
When repair makes sense—and when replacement may be better
Repair may be practical when damage is isolated, compatible materials are available, surrounding areas remain flexible and serviceable, and the repair can restore the layered water-shedding system. Replacement deserves consideration when the roof has widespread aging, recurring leaks, brittle materials, multiple incompatible repairs, deteriorated decking, or a remaining service life too short to justify repeated work.
A responsible recommendation should explain both choices when both are reasonable. Homeowners should also consider how long they plan to own the property, whether future solar or remodeling work is planned, and whether a repair can receive a meaningful workmanship warranty.
- Selecting shingles without reviewing the complete accessory system
- Reusing failing flashing or pipe boots to lower the proposal price
- Nailing too high, too low, overdriven, or underdriven
- Ignoring low-slope sections that require a membrane instead of shingles
Questions to ask before selecting the system
- Why is this material appropriate for my roof slope and design?
- Which complete manufacturer system and accessories are included?
- Will existing flashing be replaced, reused, or evaluated case by case?
- How will decking damage and change orders be documented?
- What intake and exhaust ventilation changes are included?
- Which product and workmanship warranties apply, and what can void them?
- How will landscaping, siding, windows, driveways, and neighboring property be protected?
- What maintenance and inspection schedule do you recommend after installation?
Contractor perspective
From a contractor’s perspective, the best roofing decision is rarely the product with the longest brochure warranty or the lowest estimate. The strongest result comes from matching the material to the roof, correcting deck and flashing defects, managing ventilation and drainage, and documenting the scope clearly enough that the homeowner knows exactly what is included.
How to care for the finished roof
- Inspect after major wind, hail, tree impact, or unusual water entry
- Keep gutters, downspouts, roof drains, and valleys clear
- Trim branches using qualified tree professionals and avoid scraping the roof surface
- Do not allow unqualified trades to cut or fasten through the roof without coordinated flashing
- Watch attic humidity, bathroom exhaust termination, and signs of blocked intake ventilation
- Keep contracts, invoices, product labels, photographs, warranty documents, and repair records

Frequently asked questions
Are asphalt shingles good for New Jersey weather?
Yes, when the selected product is properly installed with suitable leak barriers, flashing, ventilation, and fastening for the property’s exposure.
What is the difference between fiberglass and organic shingles?
Most modern asphalt shingles use a fiberglass mat. Older organic-mat shingles are heavier and are generally no longer the standard residential product.
How many bundles are in a roofing square?
Many common shingles use about three bundles per square, but designer and specialty products may use more. Always follow the exact product coverage.
Can damaged asphalt shingles be repaired?
Localized repairs are often possible when surrounding shingles remain flexible and compatible. Brittle, heavily worn, or discontinued products can make a durable match difficult.
Why do asphalt shingles lose granules?
Some loose granules are normal, especially when new. Heavy or uneven loss may reflect age, impact, foot traffic, manufacturing issues, or drainage concentration.
Do asphalt shingles need an underlayment?
Yes. Underlayment and leak barriers provide secondary protection and must be selected and installed according to code and manufacturer requirements.
What color asphalt shingle should I choose?
Consider siding, masonry, neighboring homes, heat exposure, resale appeal, and how the color looks in full daylight rather than relying only on a small sample.
Can asphalt shingles be installed in cold weather?
They can be installed under appropriate conditions, but handling, sealing, storage, and manufacturer temperature guidance require additional care.
