Frequently Asked Questions?

How do I know If my roof needs to be repaired or replaced?

Homeowners often neglect their roofing system until it begins to leak or other serious damage occurs. In most cases, roofing issues can be discovered way before major (and expensive) problems happen. If you notice cracked, warped or missing shingles, broken flashing, loose seams, or large amounts of shingle granules in the gutter, it’s time to call a roofing contractor. Cracked paint, peeling wallpaper or wall coverings, and discolored plasterboard can also indicate roof damage. Periodic inspections can help uncover potential problems and allow you to address them before they become a major investment.

Why do roofing warranties matter?

A new roof is a big investment, typically involving thousands of your hard-earned dollars and lasting 25, 30, 40 years, or more. As with any big investment, knowing in advance what your warranty covers could save you thousands in the event that problems arise with your roof.

When should I be thinking about a new roof?

There are a few ways to determine if it’s time to replace your roofing system.
Age: Roofing systems generally last around 2 decades. If your roof is approaching 20 years of age, it’s near the end of its useful life.

Leaks: If you see evidence of water leaking inside to your home, it probably has been leaking for quite a while. Water can damage rafters, plywood sheathing, ceilings, walls and more. Extensive structural damage can create a huge problem for homeowners. It’s often cheaper and less involved to simply replace the roof before it begins to leak.

Appearance: Shingles that have begun to curl, break, or warp are a good indication that it’s time for a reroofing service.

What should I consider when choosing a roofing contractor?

Before installing a new roof, or having repairs made, consider the following when choosing your contractor:

• Look for an established, licensed or bonded roofer and request references. Not all jurisdictions require
licensing of roofing contractors.

• Ask to see certificates of insurance to be sure both liability and workers compensation insurance
coverage is carried, and are in force during the time the roofing work is being done.

• Insist on a detailed, written estimate clearly stating the quantity of materials needed (labor charges, work specifications) which include approximate starting and completion dates, payment procedures and that any necessary building permits are secured.

• Carefully review and understand any warranty and watch for conditions that would void it.

• Use caution (ask questions) before accepting a bid substantially lower than other bids covering the same repair work.

• Contact your local Better Business Bureau to check for complaints filed against the contractor.

Will I need to new gutters when replacing the roof?

When we inspect your roof, our roofing experts will inspect your gutters as well. If we find that they’re in good shape, you won’t need to replace them. If they’re not, however, we can install new ones when we install your new roof. If you’re currently in need of new gutters be sure to contact us to schedule a free home inspection!

How does hail damage affect my roof?

Hail can damage your property in many ways. Hail damage to asphalt shingles can cause soft spots or bruising that may or may not be visible to the naked eye. Hail impact will also tend to loosen the hard granules that make up the top surface of the shingle. In some cases, hail will cause enough damage to break through the shingles’ felt matting and cause its fibers to be exposed. Another way to tell if hail has damaged your roof is by checking the roof vents. Hail will often cause dents or marks on the metal roof venting systems. If we find evidence of damage to the roof vents first, it usually means you may have sustained shingle damage as well..

My current roof is covered in dark streaks and spots, what causes this?

If you’ve found dark green, brown, or black streaks across the shingles of your roof, it’s and likely algae, moss, or fungus and while it sounds harmless, it can break down your shingles over time. We recommend having a proper roofing inspection done by a trained member of our team!

Could my new roof be installed over an existing one?

Although it may seem advantageous to install new shingles on top of your old roof because it’s cheaper, faster, and requires less labor, you could be setting yourself up for future costs (and headaches). Unless your current roofing system is completely problem free and only features a single layer of functioning shingles, your new roofing system may fail way too soon.

Many roofing contractors may be willing to simply nail new shingles on top of old shingles, but we always advises stripping the old materials complete off, all the way down to the deck, and then adding the new materials. Any defects, vulnerabilities, and potential problems in the plywood deck or truss system will go unnoticed unless you de-nail & re-nail.

Here are a few situations where you will need to remove the old roof before completing a reroofing service:

1- Shingles are missing, curled, split, or mossy.
2- The roof decking is sagging due to rot or deterioration.
3- The new shingles are lighter than your current roofing shingles. (This will cause all of the old bumps & ridges to show through the new roofing materials.)
4- Your current roofing system has more than one layer of shingles.

How long does a re-roof project take to complete?

The amount of time it will take to complete your re-roofing project will depend on the size & complexity of your roof, the weather & season, if your old roof needs removed, the size of the roofing crew, and unforeseen issues with the roofing system. A small, uncomplicated roof may only take a few days to complete whereas a large, complicated roof structure with a number of problems may take several weeks to finish. If you would like a better estimate for the completion time of your project please feel free to give us a call!

How are roofing shingles made?

Roofing shingles are made in a continuous web process.  Large rolls of glass mat are unwound and fed into the coater.  At the coater, coating (asphalt with air blown through it) is applied to the top and bottom surfaces of the sheet. Mineral stabilizers are added to the coating which improve the shingle’s fire resistance and weatherability.  Next, granules are applied to the top surface of coating.  Granules are ceramically colored crushed rock; the granules give the shingle its color, but more importantly protect the coating from ultraviolet light.  Backsurfacing is then applied to the sheet to prevent it from sticking to the machine and to other shingles when packaged.  The release tape is also applied to the back of the sheet to prevent the sealant buttons from sticking to the next shingle in the package.  The granules are then pressed into the topcoating.   Once the sheet is cooled, sealant buttons are applied.  The sealant buttons allow one shingle to bond to the overlying shingle on a roof, to prevent wind uplift.  The roofing sheet is then measured and cut into shingles.  At this stage, the two pieces of laminated shingles are adhered together.  The shingles are wrapped into bundles and stored in the warehouse until they are ready to be shipped to the appropriate location.
