Can you put a new roof over an old roof?
Sometimes code allows a second layer of shingles over one flat, sound layer, but Terra Nova Roofing & Construction does a full tear-off to the deck on every roof replacement in North Jersey, because an overlay hides rotted wood, keeps old flashing in place and adds weight to the roof. Tearing off lets us repair the deck and install ice & water barrier, underlayment and new flashing properly. Free inspection: call or text 973-200-1617.

Roof leak and roof repair questions
Why is my roof leaking?
Most roof leaks start at a joint, not in the middle of the shingles: chimney and wall flashing, cracked pipe boots, valleys, skylights and the eaves. Water also travels along rafters before it drips, so the stain is often a few feet from the real entry point. See why roofs leak.
How much does it cost to fix a roof leak?
Terra Nova's roof leak repair starts from $650, standard roof repair from $950, and emergency leak service with a temporary dry-in from $1,500. Rotted decking found once the roof is opened is extra. Details: roof leak repair cost.
What should I do when the roof starts leaking?
Move valuables, catch the water, and if a ceiling is bulging, poke a small hole in the center so it drains into a bucket instead of collapsing. Then take photos and call a roofer; don't climb onto a wet roof. Checklist: what to do when your roof leaks.
Can a roof leak without a ceiling stain?
Yes. Water can soak insulation, run down inside a wall or drip in an unfinished attic for months before a stain shows. A musty attic, damp insulation or dark spots on the roof boards are early signs. Read leaks without a stain.
How long does a roof repair last?
A repair done with matching materials and proper flashing should last as long as the roof around it. On an old, brittle roof, the next leak often starts somewhere else, which is when replacement makes more sense. See how long repairs last.
New roof and roof replacement questions
How do I know if I need a new roof?
Curling or cracked shingles, bald spots, lots of granules in the gutters, leaks in more than one place, a sagging line or soft spots and a roof near the end of its life are the main signs. Full list: signs you need a roof replacement.
How much does a new roof cost in New Jersey?
The price is set by the roof's size in squares, its pitch, how many layers come off, deck repairs, the material, chimneys and skylights, ventilation and access. Terra Nova gives you the exact price in writing after a free inspection. What moves the number: new roof cost in NJ.
Can you put a new roof over an old roof?
Code may allow one overlay in some cases, but it hides deck damage and old flashing. Terra Nova tears off to the deck every time. Full answer: new roof over an old roof.
How long does a roof replacement take?
Most residential roof replacements take 1–3 days, depending on size, layers, deck repairs and weather. Step by step: the roof replacement process.
Should I repair or replace my roof?
Repair when the roof is in decent shape and the problem is in one spot; replace when leaks keep moving, shingles are failing across the roof, or repairs would cost a large share of a new roof. Compare: repair vs. replacement.
Storm damage and insurance questions
How do I know if my roof has storm damage?
Look for missing or creased shingles, shingles in the yard, dented vents or gutters, new granules at the downspouts and fresh ceiling stains. Many wind creases can't be seen from the ground. Guide: spotting storm damage.
Does homeowners insurance cover a roof replacement?
Insurance may pay for sudden storm damage such as wind or a fallen tree, but usually not for wear and age; your policy and adjuster decide. We document the damage with photos and measurements and can meet the adjuster, but we never promise a result. Read insurance and roof replacement.
Should I call a roofer or the insurance company first?
Getting an inspection first tells you whether there is real storm damage before you open a claim. If water is coming in, a temporary dry-in protects the house from more damage while you sort out the claim. See inspection before a claim.
How do I avoid storm-chaser roofers?
Be careful with out-of-town crews knocking after a storm, pressure to sign right away, and anyone asking for a large cash deposit or your claim check. Check for a NJ license and a local address. Tips: storm-chaser scams.
Attic, ventilation and ice dam questions
What causes ice dams?
Heat escaping into the attic melts snow on the roof, and the water refreezes at the cold eaves. The ice ridge backs water up under the shingles. Full guide: ice dams and roof leaks.
How do you stop ice dams for good?
Balanced attic ventilation keeps the roof deck cold, and ice & water barrier at the eaves and valleys protects the roof when ice forms anyway. Gutters that drain freely help too. See preventing ice dams.
What are signs of poor attic ventilation?
A very hot upstairs in summer, frost or wet nails in the attic in winter, musty smells, mold on the roof boards and ice dams all point to poor airflow. Read signs of poor ventilation.
Are solar attic fans worth it?
They can help a hot attic that lacks enough exhaust, as long as there is enough intake at the soffits to feed them. We'll check whether ridge vents, soffit vents or a fan fits your roof. Read are solar attic fans worth it.
Gutter, soffit and fascia questions
Why are my gutters overflowing?
Clogs, a downspout too small for the roof area, gutters that lost their pitch, or heavy runoff from a valley are the usual causes. Fixes: overflowing gutters.
Should gutters be replaced with a new roof?
Often it makes sense when the gutters are old, sagging or attached to rotted fascia, because the drip edge and gutter apron go on during the roof job. Sound gutters can stay. See gutters and a new roof.
Do gutter guards really work?
Good guards cut down on cleaning but don't end it; fine debris and shingle grit still collect, and some guards cause overshoot in heavy rain. Read do gutter guards work.
What are soffit and fascia?
Fascia is the board along the roof edge that the gutters hang on; soffit is the underside of the overhang, often vented to feed air into the attic. Rot in either usually means water from the roof edge. See fascia and soffit explained.
Siding questions
When should siding be replaced?
Replace siding when it's cracked, warped, loose across large areas, letting water behind it, or when repairs no longer match. Read when to replace siding.
What siding holds up to New Jersey weather?
Vinyl, fiber cement and wood all work here; the choice comes down to look, upkeep and budget. We install and repair all three. Compare: vinyl vs. fiber cement.
How do I know if water is getting behind my siding?
Soft spots, peeling paint inside near windows, stains below window corners and swollen trim are warning signs. Missing flashing at windows and roof lines is the usual cause. See water behind siding.
Flat roofs, metal roofs, skylights and chimneys
How long does a flat roof last?
It depends on the membrane, how well it drains and how it was installed; ponding water and poor flashing at walls and drains shorten its life. Read how long flat roofs last and flat roof replacement.
Is a metal roof a good choice?
Metal sheds snow well and lasts a long time when the panels, fasteners and flashing are installed right; it costs more up front than shingles. See metal roof replacement.
Why does my chimney leak?
Most chimney leaks come from failed step or counter flashing, old tar patches, or a missing cricket behind a wide chimney; some come from the masonry or cap. Read chimney leaks.
Should I replace skylights with a new roof?
If a skylight is older or has leaked, replacing it during the roof job is usually the cleanest time, since the flashing gets redone anyway. See skylights and a new roof.
Hiring a roofer and reading an estimate
What questions should I ask a roofing contractor?
Ask for the NJ license number and proof of insurance, whether they tear off to the deck, how they handle rotted wood, what flashing and ventilation they include and who registers the manufacturer warranty. List: questions to ask a roofer.
What should a roofing estimate include?
A good estimate lists tear-off and disposal, deck repair pricing, underlayment and ice & water barrier, drip edge, flashing, pipe boots, ventilation, the shingle line and cleanup. Guide: how to read a roofing estimate.
Do I need a permit to replace a roof in New Jersey?
Your town's building department sets the rules for roof work, so check with them or ask us. We know local permit requirements in the towns we serve and will tell you what applies to your job. See roof permits in NJ.
