 much cheaper than other metal roofing kinds. A copper roof cost can be two times higher. Therefore, if you are searching for the best yet the less costly metal solutions, aluminum is your best option.
Remember that the total cost will depend on the kind of the system you pick (standing beam, panel, shingles, tiles, etc.). This will affect the price of materials and placement since the amount of labor varies greatly.
At Royal Roofing Inc. we have a crew of qualified and certified roofers who can place and repair any type of aluminium roofing quickly and efficiently. We will give you a detailed consultation. We will help you meet your needs and budget.
Aluminum metal shingle is an enduring and reliable alternative to typical asphalt shingle roofs. Aluminium is a durable and weather resistant material, which is why it is used in airplane production. It is strong enough to withstand extreme conditions at high altitudes. These include extreme cold, wind, snow, ice and water. The incredible properties of aluminum ensure the safety of continental travel, so you can rest assured that your aluminium roof will serve you for a long time. Aluminium will help get rid of useless expenses in roof care and often repeated roof repairs connected to asphalt roofs.

Aluminum Roofing Shingles
An interlocking design, utilized in the placement of aluminium shingles provides added durability, which has been proven by decades of service during hot summers, cold, snowy winters. The placement process consists of setting up shingles in an interlocking manner, until the entire area is covered.
Aluminium shingles are incredibly lightweight. To cover 100 square feet of space, only 40-50 lbs. of material are needed. This is 5-10 times less than the weight of conventional asphalt shingles.
Aluminium shingles are durable, can be safely walked on, provided they are well supported by the roof’s sheathing. Insulation from noise, resulting from rainfall and the like is very good, since the shingles are placed over layers of tar paper and plywood.
An aluminium roof placed expertly by experienced contractors and given its warranty for course of life delivers lasting beauty and reliable protection to your house.

TEQUESTA (CBSMiami) – A desperate call on the police radio gives a closer look at what happened the night a 19-year-old Florida State University student is accused of attacking and killing a Tequesta couple in their garage.
When deputies first arrived, they said Austin Harrouff was intertwined with John Stevens on the floor of the garage. Deputies said Harrouff was biting Stevens’ face and stomach after stabbing Stevens and his wife Michelle.
“It appeared to one of our deputies that it was like a mixed martial arts, an MMA hold, he was just wrapped around him they were body to body trying to pull them away, pry him off,” said Martin County Sheriff William Snyder.
Snyder said they were so intertwined that his deputies could not use deadly force to pull him off – it took Tasers, deputies and a dog to finally get Harrouff under control.
“We used a lot of force, up to kicking the suspect in the head. He was so intertwined with the victim they were afraid a projectile would go through him and into the victim. They didn’t contemplate using deadly force,” Snyder said.
On the radio, deputies were heard calling for help. They were also heard saying they had two possible signal sevens, which in police talk means dead bodies.
Sheriff Snyder said to this point he still has not spoken to Harrouff, who is heavily sedated.
What Snyder has gathered is that while in that garage Harrouff may have drank something poisonous.
Martin County sheriff’s investigators told WPEC, our CBS affiliate in West Palm Beach, that they are not sure if Harrouff drank the chemicals to harm himself or if he was just thirsty.
Snyder is also trying to figure out if a pair of shorts found near the scene by a news crew may have been Harrouff’s.
Harrouff remains in critical condition at St. Mary’s Medical Center in West Palm Beach. Investigators are waiting for him to become more alert so they can question him.
He tested negative for common street drugs like cocaine, heroin, marijuana and methamphetamine. The results of more extensive testing to determine whether he may have ingested bath salts or flakka are still pending.
Autopsy results show Michelle Stevens died from blunt force trauma injuries and John Stevens died from multiple injuries.
Harrouff will be charged with two counts of first-degree murder for the couple’s death, as well as attempted first-degree murder for the stabbing of the couple’s neighbor, Jeff Fisher, who suffered multiple wounds when he tried to intervene before calling 911.
Killing them to death, eh?/*
