FAQ
How much does asphalt shingle roof replacement cost in Houston?
Residential asphalt shingle roof replacement starts at $9,000 in the Houston area, varying by square footage, pitch, and decking condition. GreenSky financing is available from approximately $199/month. Call (832) 888-1666 for a free on-site estimate.
What’s the difference between 3-tab and architectural shingles?
3-tab shingles are flat, uniform, and lighter-weight, typically rated for 15–20 years. Architectural shingles are laminated with a dimensional profile, carry higher wind ratings, and typically last 25–30 years — the standard we install for Houston’s wind exposure.
How long do asphalt shingles actually last in Houston’s climate?
Most architectural asphalt shingles reach 20–25 years of service life in the Houston area, shorter than their manufacturer rating suggests, due to intense UV exposure and humidity cycling. Ventilation and installation quality are the biggest factors in reaching the higher end of that range.
Can I install new shingles over my old roof instead of a full tear-off?
We don’t recommend it. Layering shingles traps heat and moisture against the new material and hides decking damage that needs repair. A full tear-off, performed on every replacement, lets us inspect and address the decking before new shingles go on.
What shingle wind rating do I need for Houston-area storms?
We install shingles rated for at least 130 mph wind resistance given Houston’s exposure to tropical storm and hurricane-season events. Combined with a six-nail installation pattern, this exceeds the four-nail, lower-wind-rating approach some installers still use.
Does attic ventilation affect how long my shingle roof lasts?
Yes, significantly. Poor ridge-and-soffit ventilation traps heat in the attic, baking shingles from underneath and shortening their functional lifespan well below the manufacturer’s rating. We evaluate existing ventilation as part of every replacement estimate.
What time of year is best for asphalt shingle roof replacement in Houston?
Late spring and early fall offer the most consistent dry-weather windows for installation. We install year-round, but scheduling outside peak hurricane-season storm activity reduces the chance of weather delays mid-project.
How many nails per shingle do you use, and does it matter?
We use six nails per shingle rather than the four-nail minimum some crews use, which raises the wind uplift rating substantially. This detail is one of the most common causes of premature shingle blow-off during Houston storms when done incorrectly.
What underlayment do you install beneath the shingles?
We install synthetic underlayment across the full deck, with self-adhering ice-and-water shield at eaves, valleys, and penetrations per International Code Council residential roofing requirements — details that matter more in Houston’s heavy rain events than in drier climates.
How can I tell if hail damaged my shingles without going on the roof?
Check gutters and downspouts for accumulated granules after a hailstorm, and look for dented metal vents, gutters, or AC fins visible from the ground — hail hard enough to dent metal is usually hard enough to bruise shingle mats. A ground-level check is not a substitute for a professional inspection.
Do you install shingles from brands other than GAF?
Achilles is a GAF Certified Plus installer and primarily installs GAF Timberline HDZ shingles, which carry an enhanced manufacturer warranty when installed by a certified contractor. We also install Owens Corning and Malarkey Class 4 impact-resistant shingles on request.
