HOME RESTORATION PROCESS
TEAR OFF – Our crews use various techniques and tools to remove the existing shingles. The deck surface, and other wood, will be inspected and, according to Colorado building code, any damaged or rotten wood must be replaced. Keep in mind that many roof restorations and replacements will require tear off of more than one layer of shingles.
MOLD & ROT INSPECTION – There are many different stages of rot. Once rot has started it can be stopped by proper ventilation (unless it is past a certain point). Mold cannot survive in a dry, cool environment, so ventilation is crucial for mold remediation, as well as keeping the temperature of the decking down (which allows the shingles to last longer). If your attic maintains a hot moisture-laden environment, the wood decking and rafters will not last as long as they could. But if proper ventilation measures are taken, moisture and heat will not be trapped, preventing mold and rot. Ice Dams are also prevented by proper ventilation and insulation of the attic space. A hot attic causes the snow on your roof to melt unevenly and freeze at the eves; water will then dam and wick up the shingles, eventually leaking into your attic.
PRE-SHINGLE INSTALLATION – Shingling requires a proper nail surface; once that has been established with decking we will start the installation. First, we install an Ice & Water shield two feet into heated air space (1-3 rows up the eves) and up each valley. Once exposed to proper heat, this material seals around every nail and to the deck in order to help prevent ice dams. Next, we install a felt underlayment—this material is a secondary water barrier. Many building codes only require a 15 LB felt underlayment, but we utilized a 30 LB underlayment at no additional charge. This 30 LB felt is twice as thick for a better and more water resistant roof. The main purpose of felt is to maintain a Class A fire rating.
SHINGLE INSTALLATION – In most roofing installation instances, replacement of metal flashing, such as drip edge, wall flashing, and chimney/skylight flashing, should be installed. Many building code does not require these metal flashing to pass inspection and many insurance companies will not pay for them if they were not previously installed. We take extra measures for your protection and will install metal flashing where necessary. If your insurance company will not cover the cost of metal flashing installation, C.I.G. Construction will install the flashing at our expense. Flashing installation will be done in conjunction with the shingle installation. The shingle installation starts at the eves, and the crew will work their way up the ridge. Keep in mind, shingles are only one component of a roof covering; this is why it is often referred to as a roofing system. The components from the deck, felt, flashing, and shingles all work together to make the roof last the life of the warranty.
If weather permits, the entire roof replacement and restoration can be completed in one day.
