Asphalt shingle roofing, installed to spec

A shingle roof in South Mississippi works harder than one almost anywhere else: months of high heat and humidity, some of the heaviest annual rainfall in the country, and a hurricane season that runs half the year. The difference between a roof that shrugs that off and one that fails early is rarely the shingle itself. It's the system underneath and the quality of the installation.

That's why we install complete shingle systems, not just shingles: underlayment, ice-and-water protection in valleys and penetrations, drip edge, ridge ventilation, and manufacturer-matched components, fastened to spec. We're a GAF Certified Contractor and also install Owens Corning shingle products, and we'll tell you plainly which line fits your home and budget.

Shingles are only the visible layer of an assembly that works, or fails, as a whole. On many product lines, wind-warranty eligibility depends on installing a required combination of components, not the field shingle alone. From the deck up:

• Decking: a continuous, solidly supported deck; soft sections replaced before anything new goes down
• Underlayment: the water-shedding layer between deck and shingles
• Leak barrier: self-adhering membrane in valleys and around penetrations
• Starter strips: sealed edge courses at eaves and rakes, the first line of wind resistance
• Field shingles. The product you see from the street
• Hip and ridge shingles: purpose-made caps, not field shingles bent over the peak
• Flashing, metal wherever shingles alone can't seal
• Ventilation, balanced intake and exhaust so the attic doesn't cook the shingles from below

Standard fastening is commonly four nails per shingle; enhanced wind specifications and steep slopes may require six, and some wind-warranty tiers make six-nail fastening a condition of coverage. Placement beats quantity: nails belong in the marked nailing zone, driven flush: not angled, overdriven, or underdriven.

One caution: some wind warranties advertise no stated maximum wind speed when required accessories are installed. That's a warranty term, not a physics claim, no shingle is immune to blow-off. We install to spec and register what qualifies.

There's no universal winner between the brands. Both make quality architectural shingles, and the pick usually comes down to color, availability, budget tier, and warranty package. We're a GAF Certified Contractor, which affects the enhanced warranty options we can register on GAF systems; we also install Owens Corning shingle products, though we're not an Owens Corning certified or preferred contractor.

Either way, a "30-year" or "limited lifetime" label describes warranty terms, not a service-life prediction. Real service life here depends on heat, humidity, algae, ventilation, tree cover, storms, and, above all, installation quality. Algae-resistant lines help with black streaking, and steady granule loss in the gutters is the honest sign a roof is winding down.
