Frequently Asked Questions
So you're not a roofing expert. You get that. That's why you're here. We get that, too. Here are some answers for questions you might have:
How can I be sure when it's time to replace my roof?
Like a human being, a roof begins to die the moment it's born. Technically, studies show that a roof's aging process begins soon after initial installation. The aging rapidly increases during the initial "curing" phase of the roof's life cycle. It's in this early phase that shingles' edges may start curling, granule loss occurs, and blisters might develop. You may see some curling in shingles during the colder months, while they may lie flatter in the hot months. During this curing phase, the shingles enter a period of steady aging.
How can I tell whether my roof is properly ventilated?
Most shingle warranties require a lot of ventilation-as much as one square foot of net free ventilation area for each 150 square feet of floor space to be vented. Or one square foot per 300 square feet when both ridge and soffit ventilators are used together. It is vital that every homeowner understand that all manufacturers require that FHA minimum property standards for ventilation be observed. This is because poor ventilation has been proven to increase attic temperature substantially in the summer months, promote ice dam formation at the eaves of the roof in the winter in the presence of snow and increase the chance of condensation that can cause deck movement or deterioration. These conditions can cause premature shingle aging and perhaps leaks. Older homes are seldom ventilated to FHA standards. Manufacturers will reject claims for problems that can be traced to inadequate ventilation.
An effective ventilation system will help:
- Reduce attic heat build up.
- Reduce attic moisture and condensation problems which can damage insulation,the roof sheeting as well as your shingles.
- Prevent weather infiltration i.e., drifting snow and wind driven rain.
- Prevent ice dam build-up in your valley's and along your eaves.
- Pro-long the life of your roof by many years!
Ice dams form when there has been heavy snow coupled with temperatures below freezing. When warm air escapes through your ceiling or roof ventilation, the snow that is on the top of your roof heats up and begins to melt. However, once the melted snow and ice travel to your roofs overhang, it is trapped and then freezes due to the extreme cold temperatures.
Once this water refreezes, it forms an ice dam. Ice dams pose great threats to your roof, as they will cause water to begin to seep into your home. This water can cause structural damage if left untreated.Not only are ice dams dangerous to your roof but they will also cause you to lose energy in your home.
Residential Roof Warranty
There are several things to look for when reviewing roofing warranties. First, you will want to make sure that your roof is covered in the event of any defects in the materials. Fortunately, it is rare for new roofs to encounter problems, but your warranty will offer you peace of mind and the assurance that if something were to go wrong, you would be adequately protected.
The materials that the roofer uses for your project will come with a manufacturer’s warranty. Make sure that you know what the warranty is for the material that the roofer is using before you enter into a contract. You may find that you prefer to use a different material that has a better warranty than the one the roofer may be offering you. For this reason, many people prefer to use materials that come from reputable manufacturers.
In addition to the manufacturer’s warranty, the roofer or roofing company should also provide you with a workmanship warranty in case anything happens to your roof. You should look for a roofer or roofing company that has been in business for several years.
Do I need to obtain a permit in order to have a new roof installed on my home?
Yes. There are two options available for re-roofing installations. One would be to tear off the old roof before applying the new one (tear off). The second would be to lay new shingles over the existing roof (over-lay). While the second choice is the less expensive of the two options, it is not necessarily always the best choice. The limit of layers you can have on your roof here locally around Rockford is two. Now if for example you have 5 layers that doesn't mean you have to get them tore off and install a new roof. What it means is if you have 2 layers then it must be tore off you cannot put on that 3rd layer. So in summary the only time we can do an over-lay is if you have just 1 layer.
