Our technicians are background-checked and arrive in uniform, with photo-documentation equipment on every truck. The same standard we would hold for work done in our own mother’s home.

Our Roof Repair Services in North Tustin
Tile Replacement
North Tustin’s custom homes from the 1960s through 1980s were overwhelmingly roofed with clay or concrete tile, mortar-set on steep pitches that channel Santa Ana winds with real force. We regularly find cracked tiles that previous repair crews simply slapped sealant over, or worse, mortar-capped without replacing the damaged tile underneath. On a 1970s custom home in the Lemon Heights foothills, we found exactly that - a ridge cap mortar-capped over a cracked clay tile, the Santa Ana winds working the mortar loose until water ran straight into the attic. We replaced the entire ridge run with new GAF WeatherWatch underlayment and mechanically fastened ridge caps, matching the existing clay tile color. Tile replacement in North Tustin runs $450-$1,200 for localized repair, $2,800-$5,500 for full ridge or valley runs on larger hillside homes.
Flashing Repair
Hillside custom homes mean non-standard chimney penetrations, skylights set at odd angles, and roof-to-wall transitions that tract-home flashing kits were never designed for. We see standard step flashing installed where contoured, soldered metal was needed - and we see it fail when gusts hit 60 mph in the foothill canyons. Our flashing repair in North Tustin uses proper gauge copper or painted steel, formed on-site to your roof’s actual geometry. Typical flashing repair: $380-$950 for standard penetrations, $1,100-$1,800 for complex custom work on older hillside homes.
Valley Repair
Valleys on North Tustin’s steep custom roofs carry enormous water volume during our brief but intense winter rains, and the original valley metal in many 1970s homes has simply reached end of life. We replace with open valleys lined with ice-and-water shield and proper W-metal, or closed valleys with full underlayment replacement where the geometry demands it. Valley repair typically runs $650-$1,400 depending on length and accessibility.
Leak Repair
Leaks in North Tustin rarely come from obvious damage. They come from wind-lifted ridge caps, cracked mortar beds, or failed flashing that lets water travel laterally before it shows inside. Our leak repair starts with a full photo-documented inspection - we trace the water path, fix the source, and show you the pictures. Most leak repairs in North Tustin run $350-$850.
Flat Roof Patch
While less common in North Tustin’s hillside zones, we do see flat roof sections on additions, garages, and lower wings of split-level custom homes. We patch with torch-applied modified bitumen or TPO welding, matching the existing system. Flat roof patches: $400-$1,100.
Vent Boot Repair
Original rubber vent boots on 1970s North Tustin homes are now brittle and cracked. We replace with lead or high-temp silicone boots, properly sealed to the surrounding tile or shingle. Vent boot repair: $180-$340 per boot.

Common Roof Repair Problems We See in North Tustin Homes
- Mortar-set clay tiles patched with incompatible sealants instead of proper replacement. The Santa Ana winds crack tiles, and cheap repairs slop urethane or silicone over the damage. That sealant degrades in UV, the crack spreads, and water enters the underlayment. We see this on hillside homes above Jamboree Road and along Chapman Avenue - always hidden until the attic insulation is soaked.
- Flashing at custom penetrations done with standard step flashing instead of contoured, soldered metal. North Tustin’s custom chimney and skylight details require metal formed to the actual slope and surround. Stock flashing lifts in wind, separates at seams, and channels water straight to the sheathing. We replace with site-formed copper or steel, soldered at joints.
- Permits filed with the City of Tustin instead of Orange County Public Works. This is the classic out-of-area contractor mistake. North Tustin is unincorporated - city permits are invalid here. The work gets flagged at inspection, the schedule slips by weeks, and unpermitted repairs surface during home sales. We file correctly the first time.
- Ridge caps dislodged or mortar-capped over cracked tiles without replacement. The wind corridor at the base of the Santa Ana Mountains hits ridge lines hardest. We find mortar caps that look fine from the ground but are hollow over failed tile underneath. Our mechanical fastening and full replacement approach lasts.

FAQs - Roof Repair in North Tustin
North Tustin is unincorporated Orange County, with no city government of its own - all building permits must be pulled through Orange County Public Works on the unincorporated parcel system. Out-of-area contractors routinely file with the City of Tustin by mistake, which invalidates the permit and triggers re-filing delays of two to four weeks. We have filed with Orange County Public Works for four decades and know the inspection timelines and fee schedules. Call (877) 367-1429 and we will handle the permit as part of your repair.
In most cases, cracked tiles can be replaced individually if the underlayment beneath is still sound - but the repair is only as good as the inspection that precedes it. We photograph the deck and underlayment beneath every cracked tile before recommending repair versus larger work. If the original felt has degraded or previous repairs have trapped moisture, we will show you the photos and discuss partial re-roofing of the affected section. A square deal means honest guidance, not pushing work you do not need. Call for a free inspection - estimates are free.
Orange County Public Works typically issues roofing permits for North Tustin within 3-5 business days for straightforward repairs, versus 1-2 days for the City of Tustin’s incorporated area - but the real delay comes when a contractor files in the wrong jurisdiction and has to restart. We file correctly the first time, plan around OC Public Works’ inspection schedule (typically 2-3 days out once permitted), and coordinate our crew arrival so we are not sitting idle waiting for sign-off. Most of our North Tustin repairs are completed within a week of your first call.
Yes, but only with proper rigging and technicians trained for steep-slope work on irregular geometry. Our crews use full fall protection, toe boards, and material hoists on pitches above 8:12, which is standard for many Lemon Heights and Cowan Heights homes. We do not send inexperienced climbers onto roofs that require rope work. Your safety and our crew’s safety are the same standard. If your roof is particularly steep or access is limited by hillside terrain, we will discuss the rigging plan during your free estimate.
We can almost always match or closely approximate original clay tile colors through our Boral and Eagle Roofing partnerships, which maintain archives of discontinued profiles and custom-blend capabilities. Exact matches depend on the manufacturer and whether the original tile was a standard run or a custom blend for your specific builder. We bring sample tiles to your estimate and compare in natural light before ordering. Where exact match is not possible, we discuss blending replacement tiles in less visible areas or full-section replacement for aesthetic consistency. Call (877) 367-1429 to schedule a free color-match consultation.
