Metal roofing “ridge cap” is the trim placed along the roof’s ridge – the peak, where two roof slopes meet up.
A ridge cap is normally installed only after all metal roof panels and any other trim are in place. In other words, it’s put on last – the cap to the job.
Most ridge cap comes in pieces 10’6” long. They are meant to cover 10’ of ridge, with 6” of overlap between pieces. Read the rest of this entry
I’m looking to buy a metal warehouse building. The walls and roof are dirty and need cleaning. While the structure is plenty sound, I’m wondering how safe it is to walk on the roof. I was wondering if all metal roofs are built strong enough to support a person walking on it.
For other types of roofs in colder climates, building codes specify a load capacity to hold up under snow. Here in Houston, such support does not apply. As the roof itself is very light, it doesn’t need to be very strong to shed off rain.
Thinking of installing a new roof but don’t know what to opt for? Looking at the pros and cons of installing metal roofing will help you decide.
When it comes to installing a new roof, there is a wide range of options available on the market and it is quite easy and natural to become overwhelmed by the choices. This is because changing a roof is not something one would do often; it is basically a one time expenditure which an individual bears once in a very long time. Therefore, it is quite understandable that he or she may not be familiar with the options and may get confused as to which one to go for.
As mentioned there are several roofing material options on the market, like- wood shakes, clay roofing tiles, slate, concrete tiles, etc. This list of roofing materials also includes metal roofing which has become one of the most preferred alternatives and has gained significant popularity over the last two decades. Therefore, if you are a home owner looking for a suitable material to replace the roof of your house, then a metal roof may just be the right option for you. Read the rest of this entry
Metal roofs are coming back into vogue. In the late 1700s, zinc, copper, and lead were the most popular materials used for roofing – such famous historic buildings as the Washington Monument and Thomas Jefferson’s Monticello have metal roofs.
Standing-seam steel roofing is the most popular residential metal roofing today. (The term standing-seam describes the upturned edge of one metal panel that connects it to adjacent sections, creating distinctive vertical lines and a trendy historical look.) But metal roofs can also be made to resemble wood shakes, clay tiles, shingles, and Victorian metal tiles. Aluminum or coated steel is formed into individual shingles or tiles, or into modular panels four feet long that mimic a row of shingles or tiles.
Metal roofs are durable, fire retardant and almost maintenance-free. They are also energy efficient; metal reflects heat and blocks its transfer into the attic. Research by the Florida Solar Energy Center in 1985 showed that metal absorbed 34 percent less heat than asphalt shingles, and homeowners switching to metal roofing reported saving up to 20 percent on their energy bills.
Steel roofs offer other environmental benefits as well. They are made from between 60 percent to 65 percent recyclable material. Because they weigh very little, metal roofing can be installed over existing roofs, eliminating the need to dispose of excess material in a landfill.
Installing some metal roofing can be an intricate process best done by a professional, and the initial cost of a premium metal roof is higher than most other roofing materials. You need to compute the lifecycle cost to see if paying more to begin with for a metal roof will prove to be a better investment than some other form of roofing.
My vent pipe flashings are leaking due to cracking of the rubber donut which slips over the pvc vent pipe. The metal flashings are fine, only a couple years old, but the rubber is badly deteriorated. A web search mentioned that a repair collar is made to slip over the vent pipe so that you do not have to tear up the shingles to replace the entire metal unit. I have checked with plumbing supply houses but no one has heard of it. Does anyone know the manufacturers name of this repair collar or where I could buy it.
