Trusted Roof Repair for San Jose Homeowners

A roof leak in San Jose rarely announces itself politely. It shows up as a water stain on the ceiling after three days of rain, or a drip that starts at 2 a.m., or shingles scattered across the front yard after a windstorm off the Santa Cruz Mountains. Most roof repairs in San Jose run between $350 and $900 for common asphalt-shingle fixes, like Shingle Replacement, resealing flashing around a plumbing vent, or patching a small leak near a valley. Tilehurst Roofing San Jose has been doing this work under the Kingswell Guarantee since 2000. Greg Holloway and his crews show up in the window we give, put the price in writing before touching the roof, and back every repair with a written guarantee. If you’re seeing signs of a leak, call (669) 274-0078 and a live person answers, day or night.

Roof Leak Repair

Leak Repair is the work of finding where water is getting through your roof and closing that path for good. You need it the moment you see a stain, smell must, or hear a drip, because water that sits in decking or insulation destroys it quietly and expensively. Tilehurst Roofing San Jose starts every roof leak repair with a written price, then traces the leak to its true source, which is often not directly above the stain. Water travels along rafters and sheathing, so the entry point might be six feet away. Most leak repairs in San Jose run $350 – $750 for flashing fixes, vent reseals, and small shingle patches. Larger leaks involving rotted decking push toward $900 or more, and we price that before any work begins, never after.

Flashing and Vent Leak Sealing

Flashing Repair is the work of fixing the metal that wraps around chimneys, skylights, and plumbing vents, and it’s the most common leak point on a San Jose roof. Heat and UV break down the sealant around flashing over time, and that’s where water sneaks in. We remove the failed material, re-seat the flashing, and reseal it so the fix lasts beyond the next rainy season.

Ceiling Stain Investigation

A brown ring on your ceiling doesn’t tell you where the leak starts. Water runs along roof decking and only drops when it hits a seam or a nail head. Our technicians trace the moisture path back to the actual entry point before quoting the repair, so we’re not patching the wrong spot and calling it done.

Emergency Roof Repair

Emergency Roof Repair is what you need when a tree limb punches through the deck, or wind peels back a section of shingles, or a downpour finds a breach that was invisible yesterday. In San Jose, this often follows a storm system rolling through, and the urgency is real: exposed decking soaks up water fast, and that turns a $600 repair into a $3,000 deck replacement in a matter of days. Tilehurst Roofing San Jose responds to emergency roof repair calls around the clock, and a live person answers (669) 274-0078 whenever you call. We tarp and secure the damaged area first so no more water gets in, then provide a written price for the permanent repair. Most emergency roof repairs in San Jose run $500 – $1,200 depending on the damage, with the tarp and temporary seal included in that estimate.

Storm-Breach Tarping and Protection

The first job in any emergency is stopping the water where it stands. We secure heavy-duty tarp across the damaged section with battens and seal the edges so wind can’t lift it. This isn’t a permanent solution, but it buys the days you need to plan the real repair without watching the ceiling cave in.

Same-Day Structural Stabilization

When a tree limb goes through the roof, the decking and rafters need a fast assessment. We check the structure beneath the breach, brace anything that needs bracing, and give you a straight answer about what’s salvageable and what’s not. That honest read is part of the Kingswell Way: say the price before the work, and don’t oversell the repair.

Flat Roof Repair

Flat Roof Patch work addresses the low-slope and built-up roofing systems common on San Jose mid-century ranches, Eichler-style homes, and additions. Flat roofs fail differently than pitched ones: instead of shingles blowing off, you get standing water, membrane splits, and seam failures where the material pulls apart in heat. Tilehurst Roofing San Jose repairs flat roofs by identifying the failing membrane or seam, cleaning the area properly, and applying a repair that bonds with the existing surface. Most flat roof repairs in San Jose run $450 – $1,100 depending on membrane type and damage area. Ponding water left unaddressed is the enemy here, and we’ll tell you honestly if drainage corrections are part of what’s needed.

Built-Up Membrane Patching

Built-up roofs are layers of felt and asphalt, and they split at seams when the sun expands the material day after day. We clean the split, remove any waterlogged layers, and rebuild the patch so it bonds without trapping moisture underneath. A patch that seals water in does more damage than no patch at all.

Standing Water and Drainage Correction

Ponding water on a flat roof in San Jose’s dry months means the roof wasn’t pitched correctly, or drains have settled. If water sits for more than 48 hours after rain, the membrane is degrading faster than it should. We identify the low spots, clear the drains, and when it’s called for, build up the surface with a slope-correcting patch that moves water where it belongs.

Shingle Roof Repair

Shingle Roof Repair restores the individual asphalt, composite, or architectural shingles that make up the majority of San Jose residential roofs. You need it when shingles are cracked, curled, missing, or granule-bald, because each damaged shingle exposes the underlayment and decking below. Tilehurst Roofing San Jose repairs shingle roofs by matching the existing shingle as closely as possible when full replacement isn’t warranted, then sealing the repair so wind and rain can’t get under the edges. Most shingle roof repairs in San Jose run $350 – $800 for replacing a few shingles, resealing around penetrations, or fixing a worn ridge line. Larger sections that have widespread granule loss push into the $900 – $1,400 range and often indicate the roof is nearing the end of its life; we’ll give you that straight answer, with the price, before any work begins.

Single-Shingle and Section Replacement

A single torn shingle often signals worse underneath: the nail pattern may have failed, or the shingle’s seal strip released. We don’t just overlay a new shingle and hope. We pull the damaged pieces, check the surrounding seal integrity, and re-nail and seal the section so the repair actually holds through next winter’s wind.

Ridge Cap and Hip Repair

Ridge caps are the shingles that run along the peaks and hips of your roof, and they take the brunt of San Jose’s afternoon sun. When they crack or lift, water gets into the highest point of the roof and spreads downward quietly. We replace ridge caps in matching material and seal them so the highest, most exposed line of your roof is weathertight again.

Storm Damage Roof Repair

Storm Damage Roof Repair covers the aftermath of the rain and wind events that hit San Jose, from winter atmospheric rivers that dump inches in a day to the gust fronts that snap tree branches and send them through roofs or across shingle fields. You need it anytime a storm has passed and you see missing shingles, dented flashing, clogged valleys, or debris on the roof. Tilehurst Roofing San Jose assesses storm damage the way an insurance adjuster would: we document what’s broken, take photos, and give you a written, line-by-line repair price you can submit with a claim if that’s the route you take. Most storm damage roof repairs in San Jose run $400 – $1,200 depending on how many shingles went missing and whether decking got soaked. If a tree limb came through, expect the higher end and possibly more.

Wind-Lift and Missing Shingle Response

Wind gets under shingle edges and breaks the seal strip, and once one shingle lifts, the next gust catches the next one. After a wind event, you’ll often see a scatter of shingles in the yard and a bare patch on the roof. We replace the whole affected section, not just the visibly missing shingles, because the neighbors on either side have lost their seal too.

Gutter and Valley Debris Assessment

Storm debris collects in valleys and gutters, and a clogged valley sends water sideways under the shingles. We clear the debris, check the valley metal for dents or separations from flying branches, and reseal or replace the valley as needed. This is the part of storm repair that gets skipped, and it’s the part that causes the next leak.

Metal Roof Repair

Metal Roof Repair addresses the standing-seam, corrugated, and stone-coated steel systems found on a growing share of San Jose homes and some commercial buildings. Metal roofs last decades, but their screws, washers, seams, and coatings fail long before the panels themselves. You need repair when you see a rusted screw line, a popped seam, or lifted flashing at the eaves. Tilehurst Roofing San Jose repairs metal roofs by replacing worn fasteners with compatible hardware, resealing seams, and matching panel repairs when a section is dented or punctured. Most metal roof repairs in San Jose run $400 – $1,300 depending on access and whether panels need replacement. We work on Galvalume, steel, and aluminum systems, and we’ll tell you if the existing fastener pattern is a known failure point.

Fastener and Washer Replacement

Every exposed-fastener metal roof eventually fails at the fastener: the rubber washer dries out, cracks, and lets water run down the screw shaft. We remove the failed hardware, inspect the panel for corrosion around the hole, and install new screws with oversized washers that seal correctly. A roof with hundreds of failing fasteners may be a candidate for full re-screw, and we’ll price that honestly.

Standing-Seam and Flashing Repairs

Standing-seam roofs rarely leak at the panels themselves; they leak at the seams where the roof meets a wall, chimney, or skylight. Heat expansion works the metal loose over time, and the sealant cracks. We reset the seam, replace the sealant with the right product for the metal type, and make sure the flashing laps correctly over the panel below.

Commercial Roof Repair

Commercial Roof Repair covers the low-slope, built-up, and modified-bitumen systems on San Jose offices, retail spaces, warehouses, and small industrial buildings. Business leaks are different from home leaks in one painful way: they drip on inventory, equipment, or customers, not just drywall. Tilehurst Roofing San Jose repairs commercial roofs with the same Kingswell standard: a written price before work begins, a written guarantee when work is done, and a live person on the phone 24/7. Most commercial roof repairs in San Jose run $600 – $2,500 depending on square footage, membrane type, and whether the damage is isolated or widespread. We know that a commercial roof failing at 4 p.m. on a Friday is a different problem than one failing on a Tuesday morning, and we answer accordingly.

Membrane and Lap-Edge Repairs

Modified-bitumen and EPDM commercial roofs fail most often at lap edges, where two rolls of membrane meet and the adhesive or heat-weld lets go. We clean the lap, re-bond it with the right method for the material, and weigh or seal it until it’s cured. No shortcuts, because a lap that opens again in six months costs you more than the repair did the first time.

Low-Slope Drainage and Clog Response

Commercial roofs are full of penetrations: HVAC curbs, vent stacks, drain bodies, and conduit lines. Each one is a potential leak path, and San Jose’s seasonal rain exposes the ones that were sealed poorly. We re-seal penetrations, clear the drain assemblies, and report any ponding zones that indicate the roof’s slope has moved over time.

Brands We Service

If your roof carries GAF shingles, we know what those seal strips do after a decade in San Jose sun. GAF products hold up well, but the adhesive bond weakens from the outside in, and we replace GAF shingles with color-matched material that blends into the existing field. Our crews work with CertainTeed and Owens Corning systems regularly as well, so when a repair calls for matching shingle texture and color, we’re pulling from suppliers we use all year, not guessing from a photo.

For flat and commercial roofs on Atlas, Tamko, or Boral systems, our experience runs deep. Atlas products show predictable seam behavior in California heat. Tamko modified-bitumen repairs require a different bonding agent than other membranes. Boral stone-coated steel repairs call for matching the stone granule color and texture, not just the panel profile. Whether you have GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, or Boral, or any other make, we can diagnose it and fix it right.

Signs You Need a Pro Right Now

• Water stain spreading on a ceiling or wall. A stain that grows over 24 – 48 hours means active water is still entering the roof. The longer it runs, the more decking and insulation gets replaced instead of just sealed.
• Shingles or pieces of shingle in the yard after wind. If shingles came off the roof, the shingles around that bare spot have already lost their seal strip to the same wind. Rain finds that exposed area fast.
• Daylight visible through attic boards. Go into the attic on a sunny day and look up. If you see light, water has a path in. This is the cheapest time to catch a leak, before any ceiling shows a stain.
• Curled, cracked, or granule-bald shingles on sun-facing slopes. San Jose’s south- and west-facing roof planes age faster than the rest. When shingles on these slopes curl or lose granules, the underlayment is baking and will fail next.
• Damp insulation or a musty smell in the attic. Moisture in the attic means water has been getting in long enough to wet the insulation. Mold and rot follow quickly.

Our Process, Step by Step

   Call and talk to a person. You call (669) 274-0078 and a live person answers, 24 hours a day, 7 days a week. Not a phone tree, not a callback request. You describe what you’re seeing, and we schedule a time that works for you, with a real arrival window.
2. 2
   We inspect the roof and find the true source. On the scheduled day, a background-checked, uniformed Tilehurst technician arrives in the window we gave.

3. 3
   Written price before any work starts. You get a written, line-item price in your hands before a single nail is driven. That price does not change at the door, and it does not change after we open the decking, unless we find clearly hidden damage and you approve the add-on in writing first. No surprises, no pressure.
4. 4
   Repair done right, with the guarantee in writing. Our crew completes the repair with materials matched to your existing roof. Before they leave, you receive the written guarantee on the repair.
