A metal roof is a difficult area to seal the roof from the elements. One of the most important factors is the constant expansion and contraction of the surface. Expand and contract a metal roof, and so up to 2 inches per 100 feet, which can wreak havoc on fasteners and joints, which is 90% of all roof leaks occur at these sites.
If you have problems with a metal surface, then the two options, replace the roof, which can be extremely costly and timeconsume or restoration with an elastomeric coating roof that can be very inexpensive to replace the roof over.
A high-quality elastomeric roof can take many years to give life to your existing roof, are available in many different forms, but high quality ones are usually more expensive, but it should be the only choice. Lower costs of coatings does not extend far and rarely have the right built-in UV protection.
Another key feature in elastomeric coatings are energy-Savings benefit from it. Immediately after coating the temperature of the metal roof as much as 40 degrees or more may fall into a very short period of time. This reduction of heat transfer from the roof, the building is much cooler and save money on electricity bills.
The coating is not limited to work alone, there are necessary steps to ensure that the structure is properly sealed against the elements. The first thing that needs to be done is toensure a clean surface, this should be a powerful cleaner to remove scum hard to do the roof. Next you need to go around and spray the roof to stop all rust with a further corrosion of the metal. You should then go to step if there is a penetrating concrete roof with elastomeric, I mean penetrations of pipes, ventilation ducts, ventilation systems and all other areas where there is something that comes through the surface. Are also strengthenedprexisting or replace roof flashings, which can be made to the roof. After the surface is dry, the next step is to connect the individual sealing elements must be replaced with a rivet-type material and monitor all the screws are missing. After this step is necessary to protect individually seal each seam with a seam, this is mostly a roll-out band, a very thick rubber cement or a combination of both depending on the product used.
Finally, it is possible to the roof with the finaleRoofing shingles, to finish the job. You need a roof coatings sprayer, you can be sure to choose only one supplier of paints that you change the head sprayer with the correct dimensions for the roof lining. You can use a primer, depending on the product to use, and you should put two layers of coating material of the roof finish. Make sure the surface of the roof and dry, the rain now decide for the day, the prognosis over the roof. Elastomeric coating is not on a stickthe roof surface wet so make sure it is good and dry. Temperature is an important factor, should not be below 55 degrees for the crushing of the roof lining to ensure that heals well.
This is more or less as you go about your metal sealing of the roof. It is advisable to hire a qualified contractor to do the roofing work, but if you need to save money, you can complete their project.
