ROO Service
An addition is a small house built against an existing one. The foundation, the roof tie-in, and the HVAC load are what separate an addition that lasts from one that telegraphs every mistake within a year.
SVC-05 What we do
IMG Outdoor structures
A covered patio is a roof. It needs real framing, a proper tie-in, and a membrane rated for low slope — not a carport bolted onto the back of the house.
CHK Where this job goes wrong
Where the new roof meets the existing one is the single most common failure point on an addition. It needs a real framing and flashing detail, not a bead of sealant at the end of the job. We specify the tie-in in the scope and photograph it before it's covered — so if it's ever questioned, there's a record.
Get this scoped properly| Item | How it's verified |
|---|---|
| Setbacks & easements | Plat reviewed against the proposed footprint |
| Impervious cover | Checked where the jurisdiction or HOA limits it |
| Foundation design | Engineered for the lot's soil, not copied from the house |
| Roof tie-in | Framing and flashing detail specified in the scope |
| HVAC capacity | Manual J load run for the whole conditioned envelope |
| Electrical service | Panel capacity checked before new circuits are quoted |
PRC How this job runs
A roof and a whole-home renovation are different jobs, but they clear the same gates. That's what makes the schedule we give you mean something.
We walk the property, measure, photograph, and write the scope before anyone quotes a number. Attic decking, substrate condition, existing wiring, drain lines, slope — the things that turn into change orders get found here, not on day three.
Gate cleared whenSigned scope document and photo record on file.Your estimate is built line by line from a San Antonio price list we keep current — over 150 line items at real local material and labor rates. You see quantities and unit pricing, not a single lump-sum number with nothing behind it.
Gate cleared whenLine-item estimate, contract, and payment schedule executed.Permits pulled where the jurisdiction requires them — City of San Antonio, Leon Valley, Bexar County, and the incorporated suburbs each have their own rules. Selections are locked before the crew mobilizes so material lead times don't stall the job.
Gate cleared whenPermit issued, selections locked, start date confirmed.Work runs against a tracked task list with a single point of contact. Subcontractors are paid on verified completion tiers — the trade gets paid when the work passes inspection, not when it's merely started. That is why our crews finish before they move on.
Gate cleared whenInspections passed, phase sign-off recorded.You receive the permit record, warranty documents, product data, and the photo record for the job — the paperwork that matters when you sell the house or file a claim years from now.
Gate cleared whenCloseout packet delivered, final walkthrough signed.FAQ Questions
For anything with a new foundation or a structural change, yes — and most San Antonio-area jurisdictions require them for permit. We coordinate with a licensed engineer as part of the scope rather than leaving you to arrange it separately.
It's the cheapest square footage you can add because the slab and roof already exist. The honest caveats: you lose covered parking, some HOAs prohibit it, and it needs proper insulation, egress, and HVAC to count as living space in an appraisal. Done to code it appraises; dressed up it doesn't.
Plan and permit typically run four to eight weeks before anyone breaks ground, then twelve to twenty weeks on site depending on size and finish level. We give you the permit timeline separately from the build timeline so you can see where the schedule actually sits.
Often not. We run the load calculation for the whole conditioned envelope at scoping. Discovering the system is undersized after the addition is finished is an expensive way to learn it.
