What exactly does Denver, Colorado have in common with Florida?
Surely not the winters. No, winter seems quite different in both states.
What’s common are the high winds. Both states do need to cope with with damaging winds, while Denver, Colorado has never needed to suffer a hurricane. Finding the best roofing material for a Denver, Colorado home means recognizing the risk of high winds, even those that reach hurricane force.
The Dangers of Wind in Denver
A simplistic view of wind on a roof says a gust of wind just picks up fiberglass-asphalt composite shingles and rips them away. This really is named uplift, and it’s an issue. It is not the only dilemma with winds, however. Wind additionally causes. Here the pressure in addition to your roof unexpectedly drops compared to the pressure in your attic, as well as the house shoves against the roof up.
Wind shear is another dilemma, where a sudden gust of wind at a right angle to the prevailing wind direction can attack a roof with surprising force. Wind may also take airborne branches and debris that act like missiles.
No matter the material that finally surfaces your roof, you need all the attachments atop, and to think about all of the layers below , that surface. You could use metal, composite shingles, or even real or ceramic tiles, as long as mechanical fasteners are not weaker than the prevailing winds.
The very best roofing material for high winds come from every angle and will be one that works flawlessly with an entire roofing system, since the unseen forces begin inside your loft.
What Lies Beneath The Top Roofing Material
An average roof begins with sheathing, the oriented strand board (OSB) or plywood that is physically attached to your home’s rafters. The remainder of your roof is not protected, if that’s not secure. Topping the sheathing is water and underlayment /ice shield. Underlayment is usually stapled on. Most water/ice shield is self-adhesive.
Atop the underlayment your finished roof material will be seen by you. The top roofing material is neither waterproof nor wind-immune in the event the layers beneath aren’t waterproof and securely attached.
- Nailing number and patterns of nails per shingle
- Nail length (including the suggestion not to make use of staples)
- Using 30-year shingles rather than 20-year shingles
The American Society for Testing and Materials (ASTM) evaluations and ratings for enduring high winds, D3161, provides you with some comparison yardstick for picking fiberglass-asphalt shingles (composite shingles). Search for Class F ratings, which means you know the composite shingles withstand 110 mph winds for just two hours.
Class D, a lower evaluation, carries only the reassurance the shingle resisted 90 miles per hour winds for up to two hours.
Composite Shingles for roofing in Denver
Leading makers place their shingles through torturous tests to understand they will pass the ASTM Class F rating, so you understand the adhesive strips, the nailing patterns as well as the built-in strength of the fiberglass-impregnated asphalt shingle will hold up nicely in the high Denver, Colorado winds.
Metal roofing is extremely wind resistant if correctly installed. Though initially a lot higher priced than composite shingles, metal may be the very best roofing material for your scenario if:
- More than 20 years you plan to keep your house
- You’re assembling new
- You have some anxiety about fire along with winds
With metal roofing, including perpendicular seam panels, the mechanical fastening is of extreme importance in holding powerful even against 160-mph winds. Uplift issues can be addressed by noting the product’s evaluation results for ASTM standard E1592 and UL evaluation 580. & Nbsp;These evaluations ensure your Denver, Colorado house’s metal roof isn’t going to blow off from a hurricane-level pressure difference where high wind speed lowers the pressure as well as your home ’s higher pressure pushes up in your roof. Conversely, strong gusts that exert enormous loads back on the metal is not going to significantly affect metal roofing of a gauge sufficient to pass UL 580 or ASTM E1592.
Tile in Denver
Concrete and ceramic tile, installed correctly and with the mechanical fastenings that are right to pass building code, can also withstand high winds. They cannot easily defy the airborne debris, including tree branches or alternative building parts that may be thrown up by sudden wind gusts. Concrete and ceramic tiles shatter from blunt force impact, while composite shingles and metal scores may dent, crack, or dislodge, so other alternatives might be the very best roofing material.
