Is It Time for a New Roof?
Maybe. Start with the age. Most asphalt shingle roofs last about 15 to 30 years. Tile and metal can last longer. Climate matters too. Long dry seasons and strong sun wear down roofs fast.
A new roof is a big spend. So take a breath, look closely, and get facts first.
Signs Your Roof Needs Replacing
Look for these clues from the ground, or in your attic with a flashlight:
- Shingles that curl, crack, or go bald
- Dark stains on the ceiling
- Daylight peeking through the attic boards
- Granules (small gritty bits) in your gutters
- A sagging roof line
Leaks come first
A leak is the most urgent sign. Water can soak insulation and rot the wood below. If you see a drip, place a bucket and move your things. Then ask a provider to take a look. Some providers also offer emergency roof repair as a short-term fix while you plan a full replacement.
Damage after a storm
Wind and hail can harm a roof in one afternoon. If a storm hit your area, a provider can check for hail damage roof replacement needs. Some policies may cover sudden damage, so check your policy. Providers can often help document damage for a claim.
What a Roof Replacement Includes
A full job has several parts. Ask that each one appears in your written quote.
- Removing the old roofing
- Checking the deck (the wood layer under the roof)
- Adding underlayment (a water-blocking sheet)
- Setting new flashing (metal strips at joints and edges)
- Installing the new roofing
- Cleaning up nails and debris
Why the deck matters
If the deck is soft or wet, it must be fixed first. Quotes often list this as a separate line. Ask how much it costs per sheet.
What Drives the Price
Plain price talk: five things move the number most.
- Size. Roofers measure in squares. One square is 100 square feet.
- Material. Asphalt costs less than tile or metal.
- Pitch. A steep roof takes more time and safety gear.
- Layers. More old layers mean more tear-off work.
- Extras. Vents, skylights, and chimneys add detail work.
Costs vary by job. Use any range you read as a guide, not a promise. Ask for it in writing.
Choosing a Roofing Material
Asphalt shingles
This is the common pick for tract homes and ranch homes. It is simple, familiar, and widely available.
Tile
Tile suits stucco homes and hot, dry weather. It is heavy. Your home may need a check to be sure it can carry the load.
Metal
Metal sheds rain and resists embers. Some homeowners like it for areas with wildfire smoke seasons. It costs more up front.
Tear-Off vs. Roof-Over
A tear-off strips the old roof to the deck. A roof-over puts new shingles on top of old ones.
A roof-over costs less now. But it hides the deck, so hidden rot stays hidden. It also adds weight. Many older bungalows and 1950s to 1980s homes already have one layer. Rules often limit how many layers you can have. Ask the provider what your local code allows.
Permits, Timing and Weather
Most towns want a permit for a new roof. The provider often handles the paperwork. Ask who does it, and whether the fee is in the quote.
Plan around the weather. Long dry seasons are a good window for work. Winter rain events can slow a job. A good provider will cover the open roof if rain shows up.
Warranties
There are two kinds. The maker covers the materials. The provider may cover the labor. Read both. Ask how long each lasts, what voids it, and whether it passes to a new owner when you sell.
Questions to Ask Before You Hire
- Are you licensed and insured in my state?
- Will you send a written quote with line items?
- Is tear-off included?
- Who pulls the permit?
- How do you protect my yard and plants?
- What is the warranty on labor?
- When can you start?
Compare at least two quotes
Line them up side by side. A quote with a small price at the bottom may leave out parts. Check the same items in each.
Your Next Step
You do not need to know it all. You just need a plain plan. Request a callback to check provider availability, or send a request for an estimate. Many providers can respond quickly.
What's Included
Old Roof Removal
The provider strips worn shingles or tile and clears the roof down to the deck.
Deck Check
Crews look at the wood under the roof and note any soft spots that need fixing.
Water Barrier Layers
Underlayment and flashing go on first to keep rain out of seams, edges, and vents.
New Roof Install
The new material goes on, and the site is cleaned of nails and scraps.
