Roof shingles on buildings along the Miami coastline must be resistant to wind and water.

Class H roofing shingles are asphalt shingles that have been test-proven by the American Society for Testing and Materials to be highly resistant to uplift in extreme wind conditions. Based on these tests, the Asphalt Roofers Manufacturers Association has rated Class H shingles as being resistant to wind gusts from 120 to 150 miles per hour (mph). Industry standards render them useful in areas prone to hurricanes and in similar high-wind zones.



Camelot asphalt roof shingles can withstand wind assaults of up to 130 mph without detaching from underlying shingles. Their staying power is achieved with two rows of strong adhesive. They are sold with stain protection and a 10-year warranty. Specific to Camelot construction, these Class H shingles are made with two layers of granules that reflect light and block damaging ultraviolet sunrays, protecting the shingles from color fade out. Two core layers prevent shingle splitting and cracking under harsh conditions and heavy weight.

In addition, these shingles are advertised as ideal for farm structures. They do not corrode like metal roofs and they lessen noise from rain and wind, keeping animals calm. Ondura asphalt sheets come with a lifetime limited warranty.


StormMaster LM

The Atlas Roofing Corporation is the maker of Class H StormMaster LM asphalt and fiberglass blended shingles. They are approved for coastal area use by Florida's Miami-Dade county. While paint protected from weathering damage, functionality does not lie solely with the shingles but is highly attributable to the shingles' accessories. Atlas lays waterproofing material under their shingles. Water-resistant coating materials include silicone-coated polyethylene, glass and a woven polypropylene fabric. The accompanying roofing nails are resistant to corrosion.



Landmark Special Impact Resistant shingles are among the Class H roofing shingles available from the manufacturer, CertainTeed. In addition to being able to stay put in the face of strong winds, they have a fiberglass base that makes them resist damage from weight and impact. Installation requirements vary according to the steepness of the roof slope. They can require anywhere from 3 to 6 nails per shingle and some have an adhesive backing. These shingles come with a 50-year limited warranty against manufacturer defects.
