FAQ
Does a new-construction roof need a permit in Houston?
A new roof installation is typically covered under the building permit already issued for new construction, but a final roof inspection is a separate step required before the certificate of occupancy in most Harris County jurisdictions.
How long does installation take on a new build?
A typical single-family new-construction roof in Houston takes 1-2 days once decking passes inspection, weather permitting, not counting time on the builder’s overall framing schedule.
What underlayment is used under Houston’s climate conditions?
We install synthetic underlayment rated for high-humidity climates, with self-adhered membrane at eaves and valleys to resist wind-driven rain common during Houston’s storm season.
Can the roof color be matched to HOA requirements?
Yes. Shingle color and style selections are coordinated with builder or HOA-approved samples before installation begins, avoiding rework after final inspection.
Does new roof decking need to be replaced or just inspected?
On new construction, decking is freshly installed by the framing crew. We inspect thickness, spacing, and fastening pattern rather than replacing decking, unless damage occurred during framing.
What ventilation is required for new Houston homes?
Building code requires a minimum ratio of intake to exhaust ventilation based on attic square footage. This is calculated and installed before shingles go down to prevent trapped attic humidity.
Is a roof inspection required before drywall goes in?
Most builders require dry-in confirmation before interior trades begin, since an unsealed roof risks moisture damage to framing and insulation.
What warranty applies to a new-construction roof?
Installations include a 5-year workmanship warranty from Achilles Roofing & Exterior, plus GAF’s manufacturer warranty on GAF Certified Plus material systems when registered at installation.
How does Houston’s climate affect shingle selection?
Algae-resistant shingles are recommended given Houston’s humidity, and higher wind-rated products are advised for homes in areas with elevated storm exposure.
Who schedules the final roof inspection with the county?
We coordinate final roof inspection scheduling directly with your builder’s timeline and the applicable Harris County or municipal inspection department.
Can roofing start during rain delays common in Houston?
No. Installation is paused during active rain to protect decking and prevent moisture from being sealed under new underlayment; schedules are adjusted around Houston’s seasonal rain patterns.
Does flashing differ on new construction versus a roof replacement?
New construction allows flashing to be integrated with siding, chimneys, and skylights during original installation, which typically performs better long-term than flashing retrofitted onto an existing roof.
