Frequently Asked Questions
Q: How can an owner recognize roof problems?
A: Most problems are discovered after leaking or other serious damage occurs. The best way to avoid these situations is to schedule periodic inspections that can often uncover loose seams, deteriorated flashings, and other visible signs of roof system damage that may occur. As for indoors, look for cracked paint, discolored plasterboard, and discolored ceiling tiles as signs of damaged roof areas.
Q: What will a new roof system cost?
A: The price of a new roof system varies widely, depending on the materials selected, the location of the home or building, and the time of year. Keep in mind that price is only one factor, and it must be balanced with the quality of the materials. For each roofing material, there are different grades and corresponding prices, as well as varieties of styles and shapes.
Q: What is thermography?
A: Thermography is the science of using imaging to measure infrared radiation with a camera or other device that is sensitive to electromagnetic radiation. The total range in the electromagnetic spectrum classified as "infrared radiation" is 0.8μm to 1,000μm. In thermography, we use a 0.9–14μm wavelength range for imaging.
Q: What is the best roof system for a flat roof?
A: There is no one roof system that is best for all applications. Even if you are using the best materials, your roof system can still be installed improperly, leading to leaks. Good workmanship and proper attention to detail (e.g., flashing and drainage issues) are just as important as material selection. Maintenance also plays an important role in the integrity and service life of a roof system.
Q: Is my roof right for solar panels, and can my roof support the weight?
A: A solar power system can be installed on virtually any roof surface; the most limiting factor is shade. Solar panels are usually installed parallel to the roof surface and require approximately 100 sq. ft. for every 1,000 watts of DC array. Solar panels and mounting equipment add very little weight to your roof. In most cases, the solar power system will add an additional 3.5–6 lbs. per sq. ft. of weight to the roof. Virtually all modern construction built after 1970 is designed to support loads far greater than this.
