Frequently Asked Questions
Why is soldering your flashing metal so important?
If your roof contractor says they use caulk or some other sealant to keep your flashing metal from leaking you are making a serious mistake if you use their services. Caulk is just a temporary seal and your flashing work will eventually start leaking. If you solder your wall, chimney, skylight and certain valley flashing metal in the proper places the seal becomes permanent. Soldered flashings and quality roofing materials properly installed can make your roof system leak free until they both wear out
Can I just put shingles on and not replace the flashing metal?
You should always replace your wall, chimney, skylight, valley, plumbing pipe boot and any other flashings when installing a new roof. Make sure that the life expectancy of the flashing metal is the same life expectancy as your new shingles. The reason is that your roof is a system of components that work together to keep your roof from leaking. If you leave any one component out you are at risk of your roof leaking in that area. So, replace all the flashings when doing a new roof and if there installed professionally you should have a leak proof roof until the materials wear out.
How many nails should be in each full shingle?
Normal applications call for a minimum of four nails in each full shingle. Some applications call for even more if the roof is in a high wind area or the pitch of the roof is very steep. Never allow your roof to be three nailed or for staples to be used instead of roof nails.
Why use copper for my box gutter linings or my flashing installation?
Copper is a great metal to use for box gutter linings and roof flashing metal because of its longevity and that it never needs to be painted. Copper is great for lifetime, forty and fifty year shingles because you want the flashings to last as long as the life of the shingles. In the long run copper is a less expensive metal because you don’t have to paint and the life expectancy is twice that of forty-pound metal terne.
What is forty pound metal terne?
Terne is an alloy of lead and tin, used to coat sheets of carbon steel or stainless steel. Terne is used in the roofing industry for flashing metal and normally has a life expectancy of about twenty to thirty years if kept painted.
What is solder?
Solder is a lead/tin mixture that is melted and used to bond two pieces of certain types of metal together.
What is a 3 tab shingle?
Three tab shingles are shingles that have knock-outs between the square tabs and that are all the same size and exposure. This very common shingle normally has a twenty to twenty-five year life expectancy.
What is a dimensional shingle?
A dimensional shingle is a shingle that is textured, or laminated and designed to produce a three-dimensional effect. This shingle is sometimes called an architectural shingle. Dimensional shingles are a very popular style of shingle and they normally come with a life expectancy of thirty, forty, and fifty years. The higher the year of life expectancy the more three-dimensional effect you will receive on your home.
What is wrong with lining my box gutters with rubber?
Lining your box gutter with rubber is a bad idea. The box gutter frame is built with slope to your outlet tube and when the frame rots away from water damage the slope is obstructed. When you line rubber over the rotten frame you end up with pooling water in your box gutter and water flowing right over the edges. The rubber is wrapped into the outlet tube and that narrows its drainage capacity. When this happens you in up with clogs and more overflow. The right way to fix your box gutter problem is to take out the old box gutter linings. Fix the rotten wood in the box gutter frame and make sure the slope is draining to your outlet tubes. Then it’s always better to line your box gutter in terne or copper.
What is ice and water-shield underlayment?
Ice and water-shield underlayment is a continuous membrane installed under your roofing shingles in areas subject to ice damming. It prohibits water that might get under your shingles from reaching your wood structure. The membrane is made to seal nail penetrations from your shingle installation. The best places for this membrane are along your gutter lines, in your valleys, along any walls, around your chimneys and skylights.
What is underlayment felt paper and why use it?
Underlayment felt paper is an asphalt-saturated felt installed between the roof deck and the roof shingles. Underlayment is primarily used to separate the roof shingles from the roof deck. It helps to shed water during shingle installation, helps in meeting Class A and Class C shingle fire ratings, helps protect from resins that may come from wood board sheathing, helps prevent “picture framing” which is the visible outline of deck panels, cause by roof irregularities in the decking thickness, provides secondary weather protection during a wind-driven rain storm and in some cases protects your home when your shingles are blown off during a storm.

Why do my estimates range from very low to middle to very high?
If the low estimates sound to good to be true, they probably are. More than likely you will find the contractor isn’t fully insured, will cut corners while doing the work, will not have high quality materials, and will try to add something on at the end of the job. The very high estimates are usually high profile companies that have to pay for their advertising and large overhead. The best estimates to look for are the ones in the middle. Make certain that they are doing the same work item for item on your written contract, make sure you get copies of their insurance policies, make certain they use high quality roofing and flashing materials, make it clear you want references and be assured they offer a workmanship guarantee.
How do I know if the roofing contractor has insurance?
Ask!!! If the contractor is legitimate they will be able to give you copies of their Workers Comp insurance and their General Liability insurance. If they can’t then they are more than likely uninsured. DeVore Roofing will supply a copy of Workers Comp insurance in every estimate and a copy of General Liability insurance upon request.
What is the difference between a metal open valley and a woven or closed-cut valley?
A woven valley is when the shingles from both sides of the valley extend across the valley and are woven together by overlapping alternate courses as they are applied. A closed-cut valley is when the shingles from one side of the valley extend across the valley while the other side is trimmed back approximately 2 inches from the centerline. DeVore Roofing recommends the open valley method which is to install a metal valley with a center rib and to then cut the shingles on both sides of the valley back from the center rib about 2 inches, exposing the valley metal. The reason for this is that the metal channel that is created will allow the water to run smoothly down to the gutter. Also, the metal valley will stay intact for the life of your shingles. The woven or closed-cut valley system will become unsightly and wear out first because all the water from your roof drains there. The life of you roof system will be shortened because of worn valley shingles.
