Q: How much does a new roof cost?
The cost is dependent on the system you choose and the options within that system. There is a lot that goes into a comprehensive roof system. Roofing projects vary on the materials and the installers used. Most contractors provide free estimates. Before agreeing to a price, make sure you have noted the square footage of your roof, the material you have chosen for your roof, the exact quantities of all the materials that will be used to build your roof, whether or not you are keeping or removing the existing roof, any permits that are be required, and the amount of time needed to complete the work. Make sure when getting multiple estimates, the bids you are comparing are “apples to apples”. The lowest bid is not always the best option for you or your home. Mr. Roofing Project Advisors will give you a detailed design and specification in writing based on your needs.

Q: How do I determine if my roof should be replaced?
Sooner or later, every roof needs to be replaced, usually due to the long-term effects of weathering. If a residential roof is more than 20 years old, it is a prime candidate for reroofing. All too often, roof system problems are discovered after leaking 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. In your attic, take a flashlight and look at the underside of the roof deck and rafters for any stains or wet spots indicating water leaks. Indoors, look for cracked paint, discolored drywall, and peeling wallpaper as signs of damaged roof areas. DO NOT CLIMB ON THE ROOF; walking on the roof is dangerous and can damage your roof. Mr. Roofing Project Advisors can give you an honest, comprehensive, and qualified assessment of your roof’s condition.

Q: What is the lifespan of a new roof?
The lifespan will vary based on the quality of the materials used and the quality of the installation. Also, how well you follow the manufacturer’s maintenance recommendations. Most new roof systems are designed to provide useful service for about a lifetime. When done right you should only have to buy one roof system in your lifetime. Some roof system types, such as slate, clay tile and certain metal (e.g., copper) systems, last the longest.

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.

Mr. Roofing Project advisors can help you choose the right roof system and the right warranty for your property.

Q: What is Algae Block and how do I treat for moss build up on my roof?
Organic material builds up on roofs and makes it ideal for moss and mildew to grow, and all types of roof systems are susceptible. Some composition shingles come with algae block granules embedded in the material to inhibit streaking and preserve the color. There are solutions available for taking care of your specific problem, depending on the roof system material and the type of problem you’re having. You never want to power wash your composition roof system and some solutions might deteriorate certain roof materials. Ask for a free estimate, so you can get qualified answers that are right for your problem and system.

Q: How do I know if my attic is properly insulated and my roof is vented correctly?
Your attic should have an R-value of 30 for proper energy efficiency. Forty percent of a home’s energy is lost through the attic. Venting is another factor for energy efficiency and proper air flow. Without proper venting, condensation can occur and cause leaking and mold to build up, which can be detrimental to the condition of the house. The venting required is determined by the zone you live in. The best way to determine if you are properly insulated and vented is to call and set up a free evaluation with a Mr. Roofing, Inc. Project Advisor.

Q: What is edge metal and how important is it?
 Drip edge metal is a right angle strip of metal that is placed at the edge of the roof to extend it to the gutter.  Roof edges are the site of most roof failures.
It is a potential mold and rot situation as rain water can run back under the shingles and get to the decking and/or fascia (faysh-ah), thereby rotting it out down the road. If water now gets under the shingles, it can possibly cause short-term staining and long-term deterioration of the lowest edge of the roof deck and along the top of the fascia board. Prolonged existence of this condition can also affect the ends of the roof joists or trusses used to attach the fascia board.

Q: Can my roof be replaced in the winter?
Yes. It is crucial that you choose a company that is used to dealing with quickly changing weather patterns and provides a crew that is sufficient in getting the job done in a timely manner.

Q: How should I prepare for the installation of my new roof?
The installation of a new roof can affect a few things. Vibration inside the house can cause things to fall off shelves and walls, so if you have valuable items that could potentially be damaged, remove them and place in a secure location. Debris in the attic and outside–a good roofer will discuss how to protect these areas. There will also be lots of noise, so if you have pets or children, you should plan accordingly. Mr. Roofing Project Advisors provide you with an expectation list to help you plan properly for your new lifetime roof system.
