Should you consider a metal roof?

2 - Metal roofWe certainly get our share of severe weather. With the amount of hail we get, many Oklahomans have to replace their roofs every 3-6 years. While insurance will usually cover most of the cost, this roof replacement cycle is a hassle and an annoyance.

Metal roofs have a lot going for them in this regard. It’s not unlikely to get more than 20-30 years out of a metal roof in Oklahoma. While the cost is higher than a shingle roof, metal will outlast several roof replacements and you’ll recoup your investment in just a few years.

There are a lot of other significant benefits to a metal roof.

Energy efficient

Asphalt shingles absorb a lot of heat that streams into the home and increases indoor temperature by 20 to 25 degrees. Metal roofs, on the other hand, reflect the sun’s heat away from your home, resulting in energy savings of about 50 percent.

Fire resistant

One of the biggest reasons to opt for a metal roof is it’s much more fire resistant from blowing embers than shingles. This safety perk could save you money on your home owners insurance.

Water tight

We use High Temperature Ice and Water Shield under our metal roofs during installation. That’s really what keeps everything water tight. It’s made to withstand extreme temperatures from metal and tile. When a metal roof gets hailed on, it won’t leak or affect performance like composition shingles.

Good for the environment

Metal roofing is generally made from recycled content, and then, after its life, is itself recyclable.

Water savings

Metal roofs are optimal for rain water harvesting. With its smooth clean surface, less filtering is required of water from a metal roof, compared to shingles that shed small particles, and possibly other chemicals.

Happy memories

Surprisingly, most people want a metal roof for emotional reasons. They reminisce of sitting on the porch listening to the rain as a child. There are logical reasons for getting a metal roof, but at the end of the day if it can put a smile on your face, that’s what really matters.

The look

Aesthetically, a metal roof is versatile, crisp, and will complement many architectural styles, from a farmhouse to a contemporary home. Metal roofs come in different styles like clay tile, copper, slate, wood shakes, etc. There are a lot of options. Plus, it has baked on enamel and won’t fade for at least 20 years.

The downside to metal roofs is that they do get dented and scratched, like your car would. The dents will usually pop out over time with temperature changes, like cool mornings and warm afternoons.

Another downside is that HOAs often don’t allow standing seal metal roofs. They’ll usually give permission to the higher end metal roof options like wood shakes and clay tile because they blend into the neighborhood better. So, if you live with a HOA, you’re going to pay a little more for the high-end option.

Still, a metal roof is a fantastic alternative to shingles. It doesn’t take in as much heat, it’s very resistant to the elements, lasts a lot longer, and needs little to no maintenance. You can also cut down on your energy bills, possibly save on homeowners insurance, and increase your resale value.

So, if you’re tired of replacing your roof every couple years and want to make your home more energy efficient, consider a metal roof from Land Enterprise. We’ll be glad to give you a quote on shingle and metal roofing and talk through the options. Give us a call at 359-3951.

The danger of nail guns

by: Kirsten Land on September 2nd, 2014 about Commercial Roofing, Residential Roofing

Pneumatic roofing nail gunYou probably haven’t spent much time thinking about how your roof was installed. It’s shingles and nails, right? What’s complicated about that? Well, there’s a little more to it.

If you’ve ever had a shingle fly off your roof after a storm, it could be because your installer used a nail gun instead of hand nailing your shingles.

Nail guns are popular because they shorten training time and reduce effort. It takes time and practice to become proficient at hand nailing, while nail gun productivity can be achieved almost immediately. In spite of this apparent advantage, we hand nail all our shingle roofs.

The main reason is that we have more control over the depth of the nail, which must be flush with the surface of the shingle. This means the nail can’t be over-driven or under-driven.

Roofers who use nail guns will start the nail gun compressor in the morning, at the beginning of the day. Of course as the day goes on, the temperature gets warmer and the installer needs to adjust the pressure to compensate for temperature variations. What ends up happening is the installer doesn’t adjust the compressor because it’s a hassle to frequently go up and down the ladder. Instead, they’ll usually set the compressor extremely high which drives the nail too deep into the shingle. This also saves time for the installer who would normally have to hammer raised nails to “finish.”

Unfortunately, over-driven nails tend to blast completely through the shingle, creating a problem that remains unseen until high winds test the installation. Six flush nails are required to achieve a wind rating of 130 mph. If any of the nails are under-driven, you’re going to lose shingles in the next wind storm. It’s a big problem in Oklahoma because of our high winds.

Sometimes installers who use nail guns will compensate by increasing the amount of nails per shingle. However, this just increases the amount of deck penetrations which weakens the shingles over time due to thermal expansion and contraction.

The ideal nail placement is limited to a very small area. When a nail is driven outside of that area, the shingle’s wind resistance is reduced and the manufacturer’s warranty may be invalidated. Shingle manufacturers have certain guidelines they want installers to follow. They’re very particular about how many nails go into each shingle and the placement.

Proper nail placement is certainly possible when using a nail gun, but tends to be considerably more accurate when hand nailing.

That’s because with hand-nailing, you can feel when the nail misses a board. It’s a feeling you don’t get when using a nail gun. Nails driven between boards are more likely to be overlooked, which will cause raised shingles or leaking.

A lot of our installers are so used to hand nailing that it’s a comfort issue for them. They can feel when the nail is in the right place and they’re more confident in the work they do. They also have the skill and practice to hand-nail quickly. It’s intuitive after a while. They know where it’s supposed to go and what it’s supposed to look and feel like.

Sure, it takes a little more time for new installers to get trained on hand nailing, but we really feel it’s well worth the time and effort to ensure we’re building quality roofs that will withstand most anything Oklahoma weather throws are at.
