Strong winds can put significant stress on a roofing system, making wind resistance an important factor when choosing new shingles. This is especially relevant for homeowners in Orlando, where tropical storms, hurricanes, and severe thunderstorms can bring powerful winds. At Next Level Roofs, we help homeowners understand their roofing options so they can make informed decisions.
GAF shingles offer different levels of wind performance depending on the product, installation method, and roofing system. It is also important to understand the difference between a shingle's tested wind classification and the maximum wind speed covered by a manufacturer's limited warranty. Knowing what these ratings mean can make it easier to compare GAF roofing options for your Orlando home.
What Do GAF Wind Resistance Ratings Mean?
Roofing shingles can be tested using standards that measure how they perform against wind uplift. Two common standards are ASTM D3161 and ASTM D7158. Under ASTM D7158, classifications include Class D at 90 mph, Class G at 120 mph, and Class H at 150 mph. ASTM D3161 Class F represents a 110 mph wind-resistance classification. GAF notes that higher classifications indicate greater resistance to wind uplift.
These test classifications should not be confused with warranty coverage. A product may achieve a certain test classification while its limited warranty has different wind-speed terms. Installation methods and qualifying GAF roofing components can also affect the wind coverage available.
Understanding 110 MPH and 130 MPH Wind Coverage
For GAF installations that are not eligible for the WindProven Limited Wind Warranty, GAF states that maximum wind speed coverage is generally 110 mph without special installation or 130 mph with special installation.
Special installation requirements vary depending on the shingles. For LayerLock-labeled shingles, GAF specifies four nails per shingle along with GAF Starter Strip Products at the eaves and rakes for 130 mph maximum wind speed coverage. Other GAF shingles require six nails per shingle and the appropriate GAF starter strips to receive this coverage.
When reviewing a roofing system, homeowners should consider:
The specific GAF shingle being installed
Its tested wind-resistance classification
Whether special installation requirements are met
Which GAF accessories are included in the roofing system
The terms and restrictions of the applicable GAF limited warranty
Proper installation is important because shingles work as part of a complete roofing system. Choosing the right materials is only one part of preparing a roof for windy weather.
What Is the GAF WindProven Limited Wind Warranty?
Some GAF shingles with LayerLock Technology can qualify for the WindProven Limited Wind Warranty. Unlike warranties that specify a maximum covered wind speed, WindProven has no maximum wind speed limitation when all eligibility requirements are satisfied.
GAF states that the 15-year WindProven Limited Wind Warranty requires qualifying LayerLock shingles along with GAF starter strips, roof deck protection, ridge cap shingles, and either a qualifying leak barrier or attic ventilation product. Homeowners should review the complete warranty for restrictions and coverage details.
For example, GAF Timberline HDZ shingles feature LayerLock Technology and can qualify for WindProven when installed with the required GAF accessories. This roofing system approach can be worth considering for Orlando homeowners concerned about strong winds.
Why Wind Resistance Matters for Orlando Roofs
Wind can create uplift forces that pull at the edges and surfaces of shingles. If shingles loosen or blow off, the roofing system can become more vulnerable to further weather exposure.
For homeowners in Orlando, understanding wind ratings can be particularly valuable when planning a roof replacement. While no asphalt shingle can make a home immune to hurricane damage, reviewing tested classifications, installation requirements, and warranty terms can help you choose a roofing system suited to your needs.
