We know Rohnert Park roofs because we inspect them constantly, from the tight 1960s ranch houses near the golf course to the newer subdivisions off Snyder Lane. What we find almost everywhere is a roof that was built for a different climate than the one it lives in now. More on that below.

Why Brennan Roofing Is Rohnert Park’s Preferred Roof Inspection Company

Rohnert Park homeowners call us because our inspections do something most don’t: they tell you what the roof will cost over the next five years, not just whether it leaks today. Travis Oakley leads our roofing work, and he set the standard we work to on every job in Rohnert Park. That standard is The Garrison Standard, and it means the price we quote goes on paper before any work starts, the technician you meet is background-checked and in uniform, and every inspection, repair, or replacement is backed in writing for one full year.

We inspect Rohnert Park roofs the way the H-section demands: cone by cone, layer by layer, with a tape measure and a moisture meter, not from a drone or a sidewalk. Our Roof Inspection team knows that a roof that looks dry at noon off Country Club Drive can be trapping fog moisture at midnight. We scheduled for that. That’s the difference between an inspection that gives you a clean bill of health and one that tells you the truth about what’s underneath.

Our phones are answered by a live person, day or night. No voicemail, no automated system, no callback queue. When you call about a roof inspection in Rohnert Park, a person picks up. That’s never changed here and it’s not going to.

Commercial Roof Inspection in Rohnert Park

Commercial Roof Inspection in Rohnert Park means walking every plane, checking drains and scuppers, mapping the membrane seams, and determining what the building owner is actually looking at when the next heavy rain hits. We inspect flat and low-slope commercial roofs on warehouses and retail buildings in the industrial corridor near the 101, and the failure pattern is consistent: standing water that doesn’t drain, seams that have gone brittle from decades of summer heat cycling, and penetrations that were never flashed correctly in the first place. A commercial roof inspection in Rohnert Park runs $550 to $950 depending on square footage and accessibility, and it includes a written report with photo documentation and a repair-versus-replace recommendation.

Flat Roof and Membrane Evaluation

We walk low-slope commercial membranes foot by foot, probing for delamination that a visual check from a ladder won’t reveal. Rohnert Park’s hot inland valley days expand the membrane while marine-layer nights shrink it, and after enough of those cycles the seams fail long before the roof leaks. We find that and map it in a drawing, not just a description.

Drainage and Penetration Mapping

Commercial roofs in Rohnert Park fail at penetrations and drains first. We map every HVAC curb, vent stack, and drain bowl, check for ponding that exceeds manufacturer tolerance, and note where debris has dammed the flow. That map becomes the scope for repair or replacement, and it’s written down so the commercial owner can bid the work accurately.

Roof Inspection Services in Rohnert Park

Roof Inspection Services in Rohnert Park begin with the report we hand you, not the check we cashed. For a home inspection, we walk the entire roof surface on foot, inspect the attic for decking integrity and venting, check every flashing point, and test the underlayment at sample penetrations where it won’t harm the roof. We inspect detached structures too: garage roofs, carports, sheds, and ADUs. A single-family inspection in Rohnert Park runs $220 to $480; adding a detached structure generally adds $75 to $150 per building depending on size and access.

Pre-Purchase Roof Inspections

If you’re buying a house in Rohnert Park, let us inspect the roof before you sign. Sellers in this market rarely disclose overlays, and Rohnert Park’s older homes often carry two, sometimes three, layers of roofing. We document every layer, note whether the decking can support another, and give you the replacement cost in today’s dollars. That number belongs in your negotiation, and we’ll put it in writing.

Storm and Post-Season Inspections

Rohnert Park doesn’t get hurricanes, but it gets wind-driven rain off the Petaluma gap, and it gets it hard enough to peel composite tabs and lift flashing along the ridge. After big storms, we come out to check for wind damage, lifted edges, and water that got under the field. We also recommend fall inspections before the marine layer sets in for months and hides active leaks as condensation on the underside of the sheathing.

Trusted Brands We Service in Rohnert Park

We inspect and work on roofs built with product lines from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That matters in Rohnert Park, because so many homes in the Ranch were built with era-specific shingle profiles that aren’t stocked at the big box stores. We know which materials match the original roof, we can source them locally or through our supplier network, and we won’t spec a patch that looks like a patch. If your roof uses an Atlas shake-look composite, that’s what we’ll spec for the repair. No close-enough colors, no mismatched profiles. You pick the material line, and we stand behind the installation in writing.

Common Roof Inspection Problems We See in Rohnert Park Homes

• Glue-bonded overlays on skip-sheathing. In the H-section and older parts of the Ranch, the original 1965 Cox-built roofs were installed with glue so heavy that tiles and shingles bond directly to the sheathing. Inspectors who don’t know this misread the delamination pattern and call it wear. We know what we’re looking at, and we scope a re-sheet when the decking is compromised.
• Fog-trapped moisture on low-pitch planes. The Petaluma River fog rolls over Rohnert Park most summer nights and condenses on the bottom of low-slope decking. A dry afternoon inspection can miss it completely. We schedule our Rohnert Park inspections around the dew point when we can, and we always probe the sheathing under the field, not just the visible surface.
• Septic and well setbacks hiding outbuildings. On acreage lots and larger parcels, the leach field or wellhead sits right where the inspector would normally set a ladder to reach a shop or detached ADU roof. We see inspectors skip those roofs entirely. We move the equipment around the setback, not through it, and we don’t drop the outbuilding from the scope.
• Failed ridge and soffit venting on 1960s ranches. Many original Rohnert Park ranches have inadequate venting for a roof that now carries multiple layers. We check the ridge vent and soffit path during every inspection, because a sealed-up roof with passive heat buildup will cook its own shingles from the underside, even if the surface looks fine.
