Start with the size of the problem
Say you come home after a windy night and find a few shingles in the yard. Do you need a new roof? Usually not. A small bare patch on an otherwise sound roof is a repair. A roof that keeps needing patches is a different story.
The decision comes down to three things: the age and condition of the roof, how widespread the damage is, and what repairs will add up to over the next few years.
Signs a repair may be enough
- Damage sits in one small area, such as a few missing or lifted shingles.
- The rest of the roof lies flat and the shingles still look whole.
- A leak traces back to one spot, like a pipe boot or a short run of flashing.
- Nothing sags or feels soft when you look from the ground.
- The roof is not close to the end of its expected life.
Typical repair ranges on the site's service pages: replacing a few shingles runs $150 – $700, a pipe boot or vent seal $150 – $450, and flashing repair $200 – $900. Cost rises on steep or hard-to-reach roofs. A leak inspection is $100 – $400, and some providers apply it to the repair if you hire them.
Signs it is time to think about replacement
- Shingles curl, crack or shed grit into the gutters.
- You have leaks in more than one place.
- The deck feels soft or the roofline sags.
- You see daylight through the attic boards.
- Hail has marked several slopes, not just one.
- The same area has been patched more than once.
Say you have patched the same slope twice in three seasons. Each patch looked cheap. Together they are money spent on a roof that is still failing. That is the moment to price a replacement and compare.
For an asphalt shingle roof on an average home, the range is $6,000 – $16,000. Size and pitch move the price most. Tear-off and disposal add $1,000 – $4,000, and extra layers raise the cost.

What DIY can and cannot do
Some checks are safe and useful. From the ground, look at the roof with binoculars. In the attic, use a flashlight to look for dark stains, damp insulation or light coming through. Clear loose debris from gutters you can reach from a stable ladder. Take dated photos of anything odd.
The limits matter. Roofs are slippery, and a fall can cause serious injury. Do not walk on a roof that is wet, frosty, steep or high. A tube of sealant on a cracked shingle can hide a problem that keeps spreading underneath. If the deck is soft, a patch on top will not fix it.
A fair rule: do the looking and photographing yourself, and leave the climbing and cutting to a roofer.
Planning around family life
A replacement is noisy and messy, so plan for it. Ask the provider for a likely start window and how weather delays are handled. Our spring storms and summer thunderstorms can move a schedule.
- Move cars out of the driveway and clear the area near the house.
- Think about pets, naps and anyone working from home.
- Take fragile items off attic shelves and walls, since vibration shakes dust loose.
- Ask about daily cleanup and a magnet sweep for nails.
- Agree on who to contact if something comes up mid-job.
Questions to ask before you decide
Get more than one written estimate. Ask what is included, such as tear-off, deck repair, flashing and cleanup. Ask how extra deck repair is priced, since replacing deck boards runs $70 – $120 per sheet and only applies where wood is soft or rotted. Ask for proof of the license and insurance your area requires, and check it yourself.
