WARNING SIGNSMost properly installed shingle roofs will last at least 20 years before showing any significant wear and tear, depending on the type of shingle and the application materials used.

ROOFING SYSTEMS …in a Nutshell Composition shingle Is a widely used system designed for roofs having a slope of 3" or greater, measured by the roof slope rise over every 12" of horizontal travel. The typical installation has an underlayment of #15 or #30 roof felt. This layer is covered by composition shingle, which contains with asphalt saturates and a layer of granules imbedded in the matting. Laminated shingle - consisting of two layers of fiberglass-reinforced matting's that are laminated into a single unit - is most commonly used. Other types of shingle are available, and they come in a variety of styles and colors.  Just the Facts Laminated, consisting of 2 or more layers Life expectancy: 20 to 50 years TILE ROOFING Is a system consisting of shingle or tile materials made of slate, terracotta, concrete, metal or a combination of materials to create an individual roof. It is installed much like a composition shingle roof - on a sloped surface. Just the Facts Used to create an individual shingle R ratings are minimal for all  SINGLE-PLY THERMOPLASTIC MEMBRANES Are systems mechanically attached or adhered to the roof deck. These are available in 50, 60 or 80 mil thickness. All seams and penetrations are jointed using hot air welding to form a homogeneous system. Most roofs are installed using the white surface color, but other colors are available. Just the Facts Single-ply Qualifies as a cool roof Life expectancy: 20 to 25 years, with a lifetime manufacturer's warranty Recyclable No open flame or smell during installation TPO (Thermo Plastic Olefin) PUC (Polyvinyl Chloride) Just the Facts Average life expectancy: 15 to 25 years, depending on the number of layers of ply sheet installed  MODIFIED BITUMEN Is a waterproof membrane consisting of a base sheet of fiberglass matte and one to two layers of modified-bitumen-saturated polyester matting. The membrane can be installed by one of two methods: a mopping of self-adhering hot asphalt or heating and melting with a propane torch. The membrane is subject to ultraviolet damage. Coating it with aluminum roof paint or installing a top ply consisting of a modified-bitumen sheet with granular surfacing will afford the necessary protection. Just the Facts APP (A tactic polypropylene) torch applied SBS (styrene butadiene) mop, torch, self-adhered (SA)  BUILT-UP ASPHALT Is a waterproof membrane consisting of alternate layers of roofing felt and hot asphalt. Today most roofing felt is fiberglass matting with asphalt saturate. The typical system consists of a base sheet and two or three layers of ply sheet. After this system is installed, it is covered with a flood coat of hot asphalt over which clean gravel or a mineral-surfaced fiberglass cap sheet is installed. Either surfacing provides for protection from ultraviolet damage and gives the roof its required fire rating.  KNOW THE FACTS How to Size Up a Roofing Contractor A roof comprises two or more layers of materials and is never premade or premanufactured. Rather, each roofing layer is painstakingly laid by hand in a series of detailed, technical steps. These layers must accommodate the contours of the roof and the environment around the structure. A successful installation begins and ends with the services of a professional roofing contractor. Manufacturers of roofing materials routinely develop new products that perform better than their predecessors and have specific, strict installation guidelines. Make sure the roofing contractor you are considering not only is able to offer you a choice of the latest roofing products but also has experience in the installation of similar roofing systems. Roof flashings are vital for all roof systems. Most early roof failures result from incorrectly installed flashings. A quality-conscious roofing contractor will insist that there are no short-cuts to properly flashing your roof. The skills and experience of the roofing crew are critical to a quality job. Ask the roofing company about its employee recruitment and screening practices and about what training its employees undergo. A roofing company should exhibit integrity in every product it represents, sells and manufactures. If the company has faith in its products and materials, it will stand behind them. Look for performance, not just sunshine. Sometimes bad weather - rain, heat, moisture, wind - will jeopardize a job. If the conditions are questionable, a reputable roofing contractor will reschedule to work to avoid an unsatisfactory consequence. Before committing to roofing contractor, ask what if…. Neatness counts. Undeniably, roofing is a messy job. But professional preparation, such as tarping bushes and protecting building exteriors, is essential. So is clean-up. Make sure the roofing company you contract with makes the commitment in writing. Don't buy what you don't need. An ethical roofing contractor won't try to sell you a new roof when all you need is a patch repair. When in doubt, get opinions from several reputable contractors. A reliable contractor offers not just an excellent product but service and information. A company that truly respects a customer makes itself accessible and responsive to customers' questions and concerns. When a customer requests financial assistance for a needed service, a reputable roofing contractor should be able to suggest or offer a variety of payment options with favorable terms. HOW TO PROTECT YOURSELF As a consumer, there are several safety measures you can take to ensure that the company you hire for roofing services is a legitimate operation that adheres to ethical business practices. For every roofing company you're considering, you should know the following information – and don't just take their word for it, do some research on your own to make sure that all of the information they're providing you is accurate: 1. IMPORTANT: Never provide a payment before any services have been initiated. A roofing company should never ask for payment "up front" - this is a BIG RED FLAG! Advanced Roofing, as with any other reputable company, does not require a payment until we begin work on your property. At that time, we will either require the sent from your insurance company or 50% of the total cost of the project if you are providing the payments personally. 2.Go to the Secretary of State website to make sure that the company is properly registered with the state: For Washington: http://www.lni.wa.gov/tradeslicensing For Oregon: http://www.oregon.gov/CCB/Licensingl 3. Validate their general liability insurance. Ask for proof of insurance and call their insurance provider to confirm that their policy is current. The policy should cover at least $1,000,000 for each occurrence and $1,000,000 for general aggregate. You can also ask for a document called an Insurance Acord Certificate that would be written out to your specific address. This certificate basically acts as a contract ensuring that the company's general liability insurance will not go into default or be cancelled while work on your property is in progress. 4 .Make sure that they carry a worker's compensation policy. 5. Have the company provide you with their business license number. Business licenses are required in Washington & Oregon. 6. Check to see if they are accredited with any other industry related associations, such as the NRCA (National Roofers and Contractors Association). The more organizations a business is accredited to or a member of, the better. 7. Ask for references. Don't just take a company's word for it, make a couple of phone calls to people on their reference list, and talk with them about their experience. 8. Visit the company's website. What you're doing right now is one of the easiest ways to get a better understanding of a company and the services they offer. In addition to providing general information, the company should also include helpful information for the customer. 9. It may seem obvious, but be aware of appearances. Do the company and the representative present themselves in a clean, professional manner? Does their vehicle have information related to the company clearly and professionally displayed (magnetic signage can be a warning sign)? All of our representatives wear SOS Roofing shirts when conducting face-to-face business with our customers, and our vehicles are marked with professionally applied graphics that clearly show our logo, phone number and website address. |
