Where the name comes from
The company started as a two-truck operation doing repair work on the kind of roofs nobody wanted to bid: cut-up rooflines with six different flashing conditions, additions built over additions, and buildings where the previous repair had caused the current leak. The name stuck from those early years and travelled with the business as it grew into a national operation.
What did not change was the ordering. The company grew out of repair and diagnosis work, not out of replacement sales, and that origin still shapes how a job gets scoped. Replacement is one of several possible answers to the question “why is this roof failing”, and it happens to be the most expensive one. It has to earn its place in the proposal.
How we are set up
We coordinate roofing work for residential and commercial property across the United States through a vetted network of licensed and insured crews, managed against one specification and one documentation standard. That structure is deliberate, and it is worth being clear about what it means in practice.
Roofing is intensely local. Licensing is issued at state and sometimes municipal level, code requirements for underlayment, ice barriers, wind ratings and ventilation vary substantially between jurisdictions, and permitting is a county-by-county matter. A company claiming a single national crew that shows up anywhere is describing something that does not exist. What can be standardised is the part that actually determines quality: how a roof is diagnosed, how the scope is written, what gets photographed, what the warranty says, and who is accountable when something goes wrong eighteen months later.
So the crew on your roof is local and licensed where your building is. The inspection methodology, the scope format, the material standards and the follow-up are ours, and they are the same whether the building is a single-family home or a forty-unit commercial property.
What we believe about roofing work
- The inspection is not a sales instrument. A meaningful number of our inspections conclude that the roof is fine and the water is coming from a wall penetration, a failed sealant joint at a skylight curb, or condensation from an unvented bathroom fan. Selling a roof in those situations would not fix the problem.
- Photographs or it did not happen. Every finding we report is documented with an image. If a contractor tells you the decking is rotten and cannot show you, the correct response is to ask them to go back up with a camera.
- Ventilation is part of the roof. An attic without balanced intake and exhaust cooks the shingles from underneath and condenses moisture onto the deck in winter. Installing a new roof over that condition is selling someone a shortened warranty.
- Unknowns get priced as unknowns. Nobody can see the decking under an intact roof. We quote a per-sheet replacement rate up front and bill for what was actually found, rather than padding the bid or issuing a surprise change order.
- Cheap flashing ruins expensive roofs. Most leaks that we are called to fix are not field failures. They are at chimneys, skylights, wall transitions, valleys and pipe boots — the details that take time and get rushed.
Residential and commercial
The two are genuinely different disciplines and we treat them that way. Residential work is predominantly steep-slope: asphalt, metal, tile and shake, where the roof sheds water and the details govern performance. Commercial work is predominantly low-slope: single-ply membranes such as TPO, EPDM and PVC, modified bitumen and built-up systems, where the roof holds water for a period and the seams, terminations and drainage govern performance.
They fail differently, they are inspected differently, and the maintenance economics are different. A commercial membrane roof with a maintenance programme and prompt seam repair routinely outlasts its rated life by years. The same roof left alone until a tenant reports a ceiling leak usually needs a full replacement several years early. For commercial clients, that gap is the entire argument for scheduled inspection.
| Steep-slope (residential) | Low-slope (commercial) | |
|---|---|---|
| Typical systems | Asphalt, metal, tile, shake, synthetic slate | TPO, EPDM, PVC, modified bitumen, built-up |
| How it keeps water out | Sheds it — performance is governed by the flashing details at every transition | Holds it briefly — performance is governed by seams, terminations and drainage |
| Most common leak source | Penetration and wall flashing, valleys, pipe boots | Seam separation, failed terminations, blocked drains and ponding |
| Ventilation | Critical — balanced attic intake and exhaust governs covering life | Usually not applicable; insulation and vapour control sit within the assembly |
| Inspection interval | Annually past roughly ten years | Annually at minimum regardless of age, and after any rooftop trade has been up there |
| Maintenance payoff | Moderate — mostly debris clearing and detail repair | High — prompt seam repair regularly buys years beyond the rated life |
Straight answers about limits
Some things we would rather say up front than have you discover halfway through a project.
- We do not give firm prices over the phone. Anyone who does is either quoting a number they will revise later or padding heavily against what they cannot see.
- We are not a public adjuster. On storm claims we document damage thoroughly and meet the adjuster on site, but we do not negotiate settlements on your behalf, and any roofer who offers to “handle the insurance company for you” or waive your deductible is describing something that is illegal in most states.
- Weather governs scheduling. Roofing in the rain produces bad roofs. We would rather reschedule and tarp than install underlayment onto a wet deck.
- Some roofs are past repair. When a roof has three layers, widespread deck deterioration and no remaining service life, we will say so plainly rather than take a repair fee that buys you one season.
A note on storm-chasing crews. After a major hail or wind event, out-of-area operations arrive in volume, sign contracts in driveways, work fast and leave. The work is often adequate; the problem is the warranty, which is only worth something if the entity that issued it still exists and still answers. Before signing anything after a storm, ask for the contractor's state licence number and check how long the business entity behind it has existed.
Questions before you book?
Call and describe the building — roughly how old the roof is, what the covering is, and what you are seeing. If it sounds like a repair we will tell you that, and if it sounds like something other than the roof we will tell you that too. Sunny San Luis Roofing would rather be the company you call in four years than the one that sold you a roof you did not yet need.
