A stain on the ceiling shows where water arrives, not always where it gets in. Leak repair starts by tracing the water back to its entry point, whether that's a valley, a vent, a cracked shingle or worn flashing.
If water is coming in now, we can cover the damage with a tarp or shrink-wrap until a permanent repair is possible. Call any time, day or night.
Flashing is the metal that seals joints around chimneys, vents and walls. When it lifts or rusts, water follows. Includes drip edge and fascia work.
Missing, curled or cracked shingles let water reach the layer underneath. Replace them early and the damage stays small.
Slipped or cracked tiles can be replaced one by one. The underlayment beneath them is what keeps water out.
Low-slope roofs fail at seams, punctures and low spots where water pools. Many problems can be patched.

Eleven years of roof repair in Sunnyvale.

Tap what matches. You'll get the likely cause, how soon to act, and what to do next. This is general guidance, not a diagnosis. We have to see the roof to say for sure.
Likely cause: water is getting through the roof or around a vent or chimney and soaking the drywall. A ring that grows after rain points to an active leak. A stain that never changes may be old.
What to do:
Likely cause: wind, age and years of sun. Once a shingle or tile is gone, the layer underneath is exposed, and that layer is not built to take rain for long.
What to do:
Have a tile roof instead? Read the tile roof guide.
Likely cause: an opening in the roof, often from storm damage, a failed seal or a damaged vent. Water indoors can reach wiring, insulation and framing quickly.
What to do:
Likely cause: a low spot, a clogged drain or worn membrane. Water that is still sitting there a day or two after rain strains the surface and finds small cracks.
What to do:
| Sign | Likely cause | How soon |
|---|---|---|
| Brown stain on a ceiling or wall | Water getting through the roof or around a vent or chimney | Act soon |
| Missing, curled or cracked shingles or tiles | Wind, age and sun exposure | Fix this season |
| Water coming in right now | An opening in the roof from storm damage or a failed seal | Urgent. Call now |
| Water pooling on a flat roof | A low spot, clogged drain or worn membrane | Watch closely |
Most roof leaks here come from wear that built up during the dry months and showed itself in the first heavy rain.
Sunnyvale has a mild climate with long dry stretches and rain concentrated in the cooler months. Sun and heat slowly dry out sealants, rubber vent boots and the surface of asphalt shingles. When the rain returns, those weak spots let water through.
Wind and trees add to the wear, lifting shingles, sliding tiles and blocking valleys.
Roof type changes where problems start. Asphalt shingles lose their surface and crack at the edges; fixing shingle damage is usually quick when it's caught early. Tile roofs tend to fail at cracked tiles and worn underlayment, and how tile repairs work explains the steps. Flat and low-slope roofs, which you'll find on some mid-century homes, collect water at seams and low spots. See patching flat and low-slope roofs for what that involves.
Nearly every roof shares one weak point: the joints where the roof meets something else, like a chimney, a wall or a vent. Resealing flashing is often the real fix behind a leak that keeps coming back.
Repair is usually enough when damage is limited to one area and the rest of the roof is in good shape. Replacement deserves a conversation when damage is widespread or repairs keep failing. We can tell you which applies after looking at the roof.
| What you're looking at | Repair usually fits | Ask about replacement |
|---|---|---|
| How much is damaged | A few shingles, one leak, or one section of flashing | Damage across several parts of the roof |
| How the rest of the roof looks | The surface is intact and in good shape for its age | Widespread wear, bare patches or brittle material |
| Leak history | A first leak with a clear cause | The same area leaks again after repairs |
| The wood underneath | The roof deck is dry and solid | Soft, dark or rotted decking is found |
Pro tip
Ask any roofer, us included, to show you photos of the damage and of the finished repair.
Don't wait for the stain to spread
Water can soak insulation and rot the wood under the roof long before a stain shows on the ceiling. See how a roof leak is traced and fixed.

"There's a brown ring on the ceiling in the back bedroom. It got bigger after the last storm. The roof is asphalt shingle and I'm not sure how old it is."
That short description covers what, where, when and roof type. It's enough for us to know what to look for.
You don't need technical words. A few details help us plan the visit:
Never climb onto a wet or steep roof to look. A zoomed phone photo from the ground is often enough to get started.

Look for stains on ceilings or walls, missing or curled shingles, cracked tiles, shingle bits in the gutters, and daylight in the attic. Any one of these deserves a closer look, and two or more mean it's time to call. The symptom checker above shows how urgent each sign is.
It's better not to wait. A small leak still soaks insulation and wood every time it rains, and the damage grows quietly. If it only drips in heavy rain, set out a bucket, take photos, and call to schedule an inspection.
It depends on the roof and the damage, so we don't list prices on this site. Cost is driven by the roof material, the size and location of the damage, how hard the roof is to reach, how much of the wood underneath is affected, and whether the job is urgent. Ask for a written, itemized estimate after the roof has been inspected, whether by us or by anyone else you are considering.
Repair fits limited damage on a roof that is otherwise sound. Replacement is worth discussing when damage is widespread, the roof is near the end of its life, or the same spot keeps leaking. The repair or replace table compares the signs side by side.
Move furniture and electronics away, put a bucket under the drip, and keep clear of wet ceiling light fixtures. Don't go on the roof in wet weather. Then call us, any time, day or night. The emergency steps are listed on their own page.
Check the license first. In California, roofing work is generally done by a contractor licensed through the Contractors State License Board, and you can look up any license number on its website. Also ask for proof of insurance, a written estimate and a clear start date. Be careful with anyone who pushes you to pay a large amount up front or knocks on your door after a storm. That applies to us as well: we are a certified California roofing contractor, bonded and insured, and we are glad to answer these questions.
Sometimes. It depends on your policy and on what caused the damage. Take photos before any repair, keep your receipts, and ask your insurer before you sign a contract. This is general information, not insurance advice.
We are open 24/7. Call and tell us what you see on your roof. The sooner it is looked at, the less there is to fix.
