Frequently Asked Questions
Q: How can a home owner recognize when a roof system has problems?
A: All too often, roof system problems are discovered after leakage or other serious damage occurs. Periodic (twice-a-year) inspections often can uncover cracked, warped or missing shingles; loose seams and deteriorated flashings; excessive surface granules accumulating in the gutters or downspouts; and other visible signs of roof system problems.
Q: What are my options if I decide to reroof?
A: You have two basic options: You can choose a complete replacement of the roof system, involving a tear-off of your existing roof system, or re-cover the existing roof system, involving only the installation of a new roof system. If you’ve already had one re-cover installed on your original roof system, check with a professional roofing contractor. In many instances, building code requirements allow no more than one roof system re-cover before a complete replacement is necessary.
Q: My roof leaks. Do I need to have it replaced completely?
A: Not necessarily. Leaks can result from flashings that have come loose or a section of the roof system being damaged. A complete roof system failure, however, generally is irreversible and a result of improper installation or choice of materials or the roof system installation is inappropriate for the home or building.
Q: How long can I expect my roof system to last?
A: Most new roof systems are designed to provide useful service for about 20 years. Some roof system types, such as slate, clay tile and certain metal (e.g., copper) systems, can last longer.
Actual roof system life span is determined by a number of factors, including local climatic and environmental conditions, proper building and roof system design, material quality and suitability, proper application and adequate roof maintenance.
Roofing product manufacturers offer a variety of warranties on their products. Take a close look at those warranties to see what responsibilities and financial obligations manufacturers will assume if their products fail to reach their expected lives.
Q: What will a new roof system cost?
A: The price of a new roof system varies widely, depending on such things as the materials selected, contractor doing the work, home or building, location of the home or building, local labor rates and time of year. To get a good idea of price for your roof system, get three or four proposals from reputable contractors in your area. Keep in mind that price is only one factor, and it must be balanced with the quality of the materials and workmanship.
For each roofing material, there are different grades and corresponding prices. There also are a variety of styles and shapes. You need to look at the full product range and make a choice based on your budget and needs.
Within the roofing profession, there are different levels of expertise and craftsmanship. Insist on a contractor who is committed to quality work.
Q: How can I determine my annual roofing cost?
A: When considering your roofing options, the following formula may help:
Annual Roofing Cost = Total Cost (Materials & Labor)
Life Expectancy of Roof System (in years)
Don’t choose a roofing contractor on cost alone.
Price is a factor, but not the only factor you should consider. Quality roofing material and contractor workmanship have value. Hiring the cheapest roofing contractor could cost more in the long run when you consider the cost to repair sub-par roofing and the damage it causes.
Do my solar panels have to be removed to install the new roof?
Although there are rare exceptions to the rule, most solar panels are either bolted to or mounted on the existing roofing material and must be removed before a new roof can be installed. Because solar panels are charged using a type of antifreeze, they will have to be removed and reinstalled by a licensed plumber who can insure that the job is accomplished properly.
Why should I consider metal roof ?
Galvanized or Galvalume colour coated metal roofing is one of the most practical roofing materials in the market today and is “Sustainable Green Building”. It offers a long-life alternative to problem-plagued roofing materials.
Is a colour coated metal roof hot?
It reflects 70% of the sun’s energy. This minimizes heat retention and as a result, less heat is transferred into the building’s structure.
Won’t metal roof rust or its paint finish fade?
All of metal roof products are manufactured from high quality galavanized or galvanized steel, which have a coating system that protects steel from corrosion, the cause of rust. In addition, the high performance pre painted colour coating finish is guaranteed against fading and chalking.
Does a coloured metal roof attract lightening?
Lightening is attracted to the highest point, not necessarily metal. A metal roof has no greater chance of being hit by lightening than any other type of roof. However, if your roof would be struck by lightening, a metal roof can help to prevent your home from catching on fire because it can dissipate the electrical charge. More importantly, it is incombustible.
Will hail damage my metal roof?
Metal roofing products are made of high quality steel specially for hail prone areas. Hail can cause extensive damage to conventional metal roofs because it can break, split and cause tear-off. However, hail will not penetrate any metal sheets. In the most severe case, the various styles and finishes available in metal roofing can help camouflage potential cosmetic damage.
Galvalume steel in a nut shell
What is GALVALUME ?
it is a flat rolled stell sheet coated with alloy of aluminium and zinc, produced by a continuous hot dip process. It is a result of over 20 years of research. GALVALUME has an attractive appearance and has been well accepted as a preferred alternative over both galvanized steel sheets and aluminium coated steel sheets used in areas such as roofing, cladding, gutters and accessories
EXCELLENT CORROSION RESISTANCE
The improved corrosion resistance of 55% Al-Zn alloy coated steel coils is derived from the unique combination of the barrier protection of the aluminium and the sacrificial protection of the zinc. The formation of an insoluble aluminium oxide layer provides the barrier protection while the zinc provided a sacrificial protection at cut edges, scratches and areas of coating damage.
Out door exposure testing
Outdoor exposure testing of 55% AL-ZN alloy coated steel coils has been conducted for over 20 years in various atmospheric environments. The testing also demonstrated a superior cut edge protection of 55% Al-Zn alloy-coated steel sheet than galvanized steel sheet.
