Roofing questions, answered
How long does a roof last?
It depends on the material, the quality of the installation, ventilation and the climate. Asphalt shingle roofs wear fastest on the sunniest slopes, while tile and metal roofs can last much longer. Condition matters more than age, which is why an inspection is more useful than a rule of thumb.
Can a leaking roof be repaired instead of replaced?
Often, yes. Many leaks come from a single point such as flashing, a pipe boot or a few damaged shingles. If the rest of the roof is in good condition, a repair makes sense. If leaks are appearing in several places or the roofing is worn out overall, replacement may be better value.
Do I need a permit to replace my roof?
Re-roofing usually requires a permit, and many jurisdictions inspect the work. Requirements vary by city and county. Ask your contractor who pulls the permit and whether its cost is in the quote.
What causes ice dams?
Ice dams form when heat escaping from the house melts snow on the upper roof, and the water refreezes at the colder eaves. The ridge of ice traps more meltwater, which can back up under shingles and into the house. Better attic insulation and ventilation are the long-term fix; ice and water barrier along the eaves helps protect against leaks.
How often should gutters be cleaned?
At least twice a year in most areas, typically late spring and fall, and more often if trees overhang the roof. Clogged gutters overflow against fascia and siding, can send water toward the foundation, and in cold climates contribute to ice buildup.
What should I do right after a storm damages my roof?
Stay off the roof. Check for leaks inside, take photos, and contact your insurance company. A roofing contractor can install a temporary tarp to prevent further damage. Be wary of door-to-door storm chasers who pressure you to sign immediately.
Is it worth installing a new roof over the old one?
Some codes allow one overlay layer, and it can cost less up front. But a tear-off lets the contractor inspect the deck, replace flashings and install new underlayment, which usually produces a better, longer-lasting roof. Ask what your local code allows and what the contractor recommends.
Why does my attic get so hot?
Attics heat up when the sun beats on the roof and the attic lacks enough ventilation to let the hot air escape. Excess heat shortens shingle life and makes air conditioning work harder. Balanced intake and exhaust vents, along with adequate insulation on the attic floor, help.
What's included in a roof inspection?
A thorough inspection looks at the roofing material, flashings, vents, ridge, gutters and signs of previous repairs, plus the attic for leaks, ventilation problems and damp insulation. You should receive a written report with photos and clear recommendations.
How can I tell if a roofing estimate is complete?
A complete estimate lists the materials and brands, whether the job is a tear-off or overlay, how damaged decking will be handled and priced, flashing and ventilation details, the permit, cleanup, the schedule and the warranty terms. Compare these items across quotes, not just the total price.
