Q. What Warranties Do You Give?
A. We give a standard 10-year or 15-year warranty against leaks and defects in workmanship. If the work is done correctly, after the first rain or high wind you will know your roof is correctly installed.

Q. How long will it take to finish the new roof?
A. Of course, this will depend mostly upon the size and difficulty of the project. But in most cases its one-day job.

Q. Why does one of my neighbors have metal showing in their "valley," and my other neighbor doesn't?
A. The simple answer is that there are different methods of installing a valley (that section of a roof where angles meet). Two of the most common, are the open valley and closed valley. Which style you choose is up to you. But we recommend open valley with Ice & Water Shield Protection under the metal.

Q. How many vents should I have on my roof?
A. One vent is needed for every 320 square feet of roofing surface.

Q. Why is Ventilation important?
A. Inadequate ventilation can cause attic moisture and condensation, ice dam in the wintertime and excessively high attic and shingle temperatures in the summer. Also, most shingle manufacturers warranties are voided if proper ventilation is not installed. Even if you feel you’ve had satisfactory ventilation performance with your old roof for as long as 20 years, it might be necessary to add ventilation with your new roof to meet the standards.

Q. What does " ICE & WATER SHIELD PROTECTION " do and where does it go?
A. The technical term for this is "waterproofing shingle underlayment." This is a self-sticking material that goes directly onto the wooden "deck" of the roof. It should be placed, at the minimum, on the bottom of the roof, near any eaves (on slopes under 4/12), as well as under any valley systems installed on the roof. The manufacturer also recommends, for complete protection, to place the "ice-guard" on the "rake" (the side of the roof edge), the ridge, the hip, and any roof penetration, such as skylights, pipes, or chimneys.

Q. What function does the single underlayment serve?
A. An underlayment, commonly known as roofing felt, will provide a degree of backup protection in the event water gets under roofing shingles.

Q. How will my house be protected while the old roof is torn off?
A. Usually, plywood is used to divert old materials into a dumpster or truck. All windows, doors, and flowerbeds would be protected. Tarps would be spread out all around the house wherever loose debris might fall. The final cleanup should involve the use of magnets, both handheld and wheel-mounted. When finished, the only sign of a contractor's presence should be the beautiful new roof, not broken shrubs, scratched garage door and a lawn full of nails.

Q. How do I choose the best shingle?
A. Today, shingles are compared based on the length of their manufacturer’s warranty. In general, the heavier and more durable (and more expensive) the shingle, the longer the term of the warranty. Today’s shingles offer many new “textures” than were available a few years ago. These new shingles can approximate the look of hand split cedar shake and slate roofs. So you have a wide variety of colors, textures, and performance to choose from. We will help you wade through all the options.

Q. Is there a difference between Traditional and Laminated Shingles?
A. Laminated shingles not only do not cost much more than traditional ones, but they usually look better and have a longer warranty. However, if you cannot see much of your roof when standing in your yard, you may just settle for a 25 or 30-year tab shingle. You might also consider shingles that contain bits of zinc and other metals that will help prevent the growth of mold, algae and lichen. We will gladly to walk you through your options during our first meeting.

A laminated shingle refers to a shingle that has two layers in areas of fiberglass - reinforced asphalt laminated with a fiberglass base into a single unit. This single unit construction effectively seals out rain, sleet, snow, ice and wind without curling, rotting, warping, or losing tabs. The lamination process doubles the layers of the shingle, giving your home's roof a thicker, more high-profile look than any ordinary shingle can. Other names for laminated shingles are dimensional shingles and architectural shingles.

Q. What is roof slope? Does the slope of the roof limit the choice of shingle that can be use?
A. The slope of the roof is measured by the rise versus the run, or the number of inches vertically by the number of feet horizontally. Some roof slopes can limit the choice of shingles that can be used.

For Instance:
A roof slope below 2/12 (2 inches per one foot) cannot use shingles.
Roof slope between 2/12 and 4/12 require low-slope application techniques, including application of waterproofing underlayment as appropriate.
Roof slopes above 12/12 require steep-slope application techniques.

Q. How can I get samples of shingles?
A. Our supervisor can come out to your home and help you determine what style of roofing would be best for your home. They can provide samples of our products.

Q. Why does my roof leak?
A. Well, a cynic answer might be that there are two kinds of roofs: those that leak and those that will leak. Roofs leak from a break in the waterproofing layer, sometimes caused by mechanical damage, sometimes from an opening in the sealant, such as pitch pans and caulking, and sometimes from deterioration or defects in the roofing material.

Q. How long should a roof last?
A. Like any building component, roofs degrade at different rates depending on a large number of factors: the quality of original construction, the level of abuse, the level of maintenance, appropriateness of design, etc. So how long should a roof last? We have seen poorly designed and installed roofs go as few as six or seven years before they failed, and we have seen old coal tar built up roofs that were over 60 years old. Most building owners, roofing contractors and designers feel 20 years is an acceptable service life.

Q. Can I cover over my existing roof?
A. Installing a roof over the top of an existing roof is generally acceptable under these guidelines:
  • 1) A building cannot have more than two roofs;
  • 2) No wet insulation can be left in place;
  • 3) The roof structure must be able to handle the additional roof load;
  • 4) The new roof must be attached to the roof deck to meet wind loads (it is not generally acceptable to adhere the new roof to the old roof).

Q. What time of year is the best time to install a roof?
A. The optimum time to install a roof is when the temperatures are above freezing and the wind and rain are at the lowest intensity and frequency. This allows the roofer the best conditions for installation, with the fewest interruptions and lowest risk of leaking. Unless you are very fortunate, sometimes you cannot schedule the roofing work during these periods, and you may need to install t he roof in cold temperatures, or in the rainy season. If you know this in advance, it may be possible to choose a roof system that is more tolerant of in climate weather.

Q. How do I know when my roof needs to be replaced?
A. The 3 most common factors are Age, Appearance and Leaks.

Age: If the roof is around 20 years of age it may be nearing the end of its life depending on the quality and warranty of the roof. There is also some variation based on sun exposure, shingle color and ventilation under the roof.

If you are unsure of the age then your next evaluation factor is:

Appearance: If you have shingles that have broken off, look buckled or warped, or have lost some granule surfacing, it is probably time to consider a replacement.

Leaks: This is obviously not the best way to find out you may need a new roof. By the time you find water leaking inside the house, it has probably started quite a while prior to your finding. The leaking can cause structural damage to the rafters and the boards on top of them, not to mention to your ceilings and walls. It is much less expensive to replace your roof before you see leaks.

Q. What do I need to do to prepare for the installation of my new roof?
A. Remove all loose items from walls and shelves. The constant hammering may cause enough vibration to shake these items down. Make sure to clear your driveway and items directly surrounding your home. Also, please see that electrical power is provided to the outside of your home. If exterior plugs are not available, please run an extension cord through a garage door or window.

Q. How much does a new roof cost?
A. Before we can tell you how much your job will cost, we will need to know what it involves. We understand your concerns about budget and keeping costs under control. We have the same concerns ourselves. Therefore, the best way to estimate a cost is to have a ReRoof.ca supervisor come to your home and take a look at your roof.
