Roofs with chimneys, dormers, porch roofs and other details have more places for water to get in. If your home in the Murphy area has a roof like that, call (669) 240-7171 and describe what you see. This page explains where leaks hide on complicated rooflines, how repairs are matched to what is already there, and what to plan for on a tight lot.
Roof repair help for homes in the Murphy area
Roofs differ from house to house, whatever the neighborhood. A simple gable roof has a ridge, two slopes and an edge. A roof with a chimney, a dormer, a porch roof and a bay window has many more joints, and each joint is a place that depends on flashing and sealant to stay watertight.
That makes leaks harder to trace. If you are trying to work out where one starts, read about finding a leak on a complicated roof and begin with the roof features nearest the stain. If the stain is close to a chimney, dormer or wall, read about chimney, dormer and wall joints. For all the neighborhoods we cover, see the areas we help in.
Where leaks hide on complicated rooflines
| Roof feature | Why it leaks | The clue |
|---|---|---|
| Chimney | Flashing and mortar age on all four sides | A stain on the ceiling or wall next to the fireplace |
| Dormer | It has its own walls and valleys that all need sealing | Stains at the corners of the dormer room |
| Porch or bay roof meeting a wall | Water runs down the wall into the joint | Stains on the outside wall above the lower roof |
| Skylight | Seals around the frame dry out and open | A ring-shaped stain around the opening |
| Valley between roof sections | It collects water, and debris backs it up | A stain that follows a line under the valley |
| Plumbing vent stack | The rubber collar around the pipe cracks | A stain near a bathroom or kitchen wall |
Chimneys: roofer or mason?
Two different kinds of work can be involved. We handle the metal flashing where the chimney meets the roof. A mason handles the brick or stone, including cracked mortar and a damaged crown, which is the cap on top. Water that gets in at the top of a chimney can show up as a ceiling stain, and it can look just like a roof leak.
Ask us to tell you which part is failing. If the masonry is the problem, you may need both trades. Looking only at the flashing can miss it.
Keeping repairs in line with the rest of the roof
If appearance matters to you, tell us up front. On tile roofs, repairs are easier to blend in when matching or spare tiles are available. See how repairs that keep matching tile in place are handled. On shingle roofs, the closest color is chosen, and it settles over time.
Some homes and some communities have design rules or review requirements that apply to changes in visible roofing. Check with the city or your homeowners association if you think yours might, and ask us to confirm what applies before work begins.
Planning a repair on a tight lot
On a home with a narrow side yard, a short driveway or limited street parking, the logistics matter as much as the repair. Talk through these with us before the day of the work:
- Access. Where the ladder or scaffold will go, and whether the crew needs to cross your yard or a neighbor's.
- Parking and materials. Where trucks and materials will sit, and whether any street use or dumpster needs city approval. We will check what applies.
- Overhead lines. We plan around power lines near the roof. Never go near them yourself.
- Landscaping. Plants and fences near the house can be covered or protected.
- Neighbors. Noise and debris can reach next door, so a quick heads-up is polite.
Help us find the leak on a complicated roof
The more you can tell us about the stain and the weather, the faster we can narrow it down. Collect these before the visit:
- Sketch the roof. A simple drawing showing the main sections, the chimney and any dormers or porch roofs.
- Mark the stain on the sketch, and note which room it is in.
- Note the weather. Does it leak in heavy rain, wind-driven rain, or every rain?
- Photograph the outside of the roof features closest to the stain, from the ground.
- Check the attic near that spot with a flashlight, if you can do it safely.
Pro tip
If the leak only happens when rain comes from one direction, tell us which way. It often points to the exact wall or joint that is taking the weather.
What to ask any roofer
- Which of the roof's features did you inspect, and which one is leaking?
- Is the problem the roof, the chimney masonry, or both?
- How will the repair be matched to the existing roofing?
- What do you need from me for access, parking and protecting the yard?
- Is the scope in writing, with any masonry or interior work listed separately?

Questions about this repair
Why does my roof leak near the chimney?
The chimney is a joint between two different materials, and it depends on flashing and mortar to stay sealed. Those wear with sun and movement. A leak there can come from the flashing, from cracked mortar or from a damaged chimney crown.
Do I need a roofer or a mason for my chimney?
Possibly both. We handle the metal flashing where the chimney meets the roof. A mason handles bricks, mortar and the crown. A good inspection tells you which part is failing.
Can you match the roofing I already have?
Often we can come close. Matching depends on the material, how long it has weathered and whether the same product is still made. Spare tiles or shingles from the original installation make it easier.
Do I need a permit for roof repair?
Rules vary with the type and size of the work. Many small repairs are simpler than a full replacement, but ask us to confirm what applies in Sunnyvale, and check with your HOA if you have one.
How do I find where a leak comes from on a roof with many sections?
Sketch the roof, mark where the stain is, and note the weather when it leaks. Look at the roof features closest to the stain, such as a chimney, dormer or wall joint. Our inspection confirms the source.
