Be Prepared Be Efficient
Inspect ~ Materials should be sent the day before installation work is scheduled to begin. Ask for a material list from the supplier to be included with the delivery and compare it with your contract. Shortcuts are easily avoided by having the correct materials on the jobsite before the work begins.   Tie Tarps to the Roof ~ Tall bushes are sometimes directly below the roof line. To be cleaned more thoroughly, nail tarps from the roof and lay over top of bushes.
Cleaning / Hammering / Dumping
Clean Off Nails ~ Before hammering in a nail it is best to clean the old debris around it first. Old nails tend to surface years later if they are not properly cleaned off and smoothed out.   Donít Dump In the Rain ~ The road down into the dump is very steep so we advise caution when entering. At the same location thereís a smaller dump you may unload your truck by hand.
Tractor Pull ~ The tractor pulls a chain wrapped around a tire covered by the shingles off the back of the trailer. It happens quicker than a bull ride.    
Plywood & Rafters
Inspect Thoroughly ~ If a rafter is rotten it should be removed and a new rafter installed. This problem is very often overlooked because the cost of the repair is usually very steep. Please be sure a contingency plan between the roofing contractor and the home owner is in place before any labor on the roof repair starts.   Sistering ~ The easiest and most cost efficient way to repair this problem is to remove the rotten part of the old rafter and nail the new rafter directly beside it (far right rafter).
Cool Ply & 1x4 Realignment
Be Aware of Wires ~ When you are installing radiant barrier plywood after removing old wooden cedar shingles, remove only every other 1x4. If ALL are removed there could be trouble with the wiring in the house.   Realign the 1x4ís ~ When you are installing plywood after removing old wooden cedar shingles, be sure to pull up the 1x4ís as youíre laying the decking to make a ledge for each sheet (all plywood must also be laid with the grain).
  Rafter Straightening
Inspections ~ A house could not pass inspection when trying to sell if the roof decking was not installed properly.   Remove Plywood ~ Roofs sometimes look like they have huge dips or waves in them because of the rafters being un-centered, foundation problems or poor workmanship at the time of original construction. The new roof will look the same unless you address the issue by reframing the rafters.
Fascia Boards
New 1x2ís ~ Always include drip edge in the ordering of a new roof. On the upper edge of the fascia board next to the shingles there should be a 1x2 strip of wood also. These two items when installed properly help protect the fascia board.  
Felt Paper
2~12 Pitch and Up ~ 15# and 30# felt is used underneath the regular asphalt shingles. 30# is for slopes between 2 and 4~12 pitch or a 9~12 and above. Watch the roofers as they tear off because this is one of the most common roofing short-cuts. On some roofs it is possible to remove the top layer of shingles only, then nail the new shingles on top of the same old felt. It could save the roofing company as much as $10.00 per square when this occurs so if you do choose a roofing contractor, ask for a complete tear off and make sure itís in writing.     
Weather Guard
Cold Applied ~ Just Peal off the back and it sticks to the plywood and when it heats up it seals all the nail holes. It sounds great but in most cases it is not. This is a commonly used product for add-ons or sheds etc. When the pitch of a roof is lower than 3~12 there is nothing that will keep the water out better than a torch applied modified bitumen. Laying this stuff down before using plain asphalt shingles is a nightmare waiting to happen.    
Base Sheet
Melts to Torch Applied Bitumen ~ The white material on the left is base sheet and it is melted to the torch applied modified bitumen. There are no exposed nail holes after installation and is warranted by the manufacturer for 10 years.    


Chalk Lines
3-Tab Only ~ Felt paper lines are almost never laid strait so it is best to pop chalk lines as your guide. When applying a 30 Year shingle or greater chalk lines are not necessary because the correct line is on top of each shingle.   Gables are Difficult ~ Measure from the fascia board on each end and calculate precisely the right distance or some shingles could be exposed to much and cause an unsightly scene.


Asphalt Shingle Starters Modified Starter
Pre-Cut Seal Better ~ There are shingles made specifically to use as the first row of shingles. They have a tar strip on the very edge of the shingle where the first row meets the drip edge. Years ago the installers just flipped a regular 3-tab shingle upside down and the sealant would be in the middle of the shingle instead of the very edge.   Always Use ~ On a flat roof it is best to cut some of the modified and turn it upside down before laying the gravel guard.


Masonry Saw Blade
Cut 2/3" Gap ~ A masonry saw blade is different than a wood blade. A wood blade when used on brick tends to chip the brick while a masonry blade sands the brick leaving it mostly intact.   Wear a Mask ~ There is usually very large amounts of dust when cutting into a brick chimney because the masonry blade is grinding like sand paper.
Snug Fit ~ Counter Flashing has a special lip which pushes into the brick.   No Leaks ~ There will never be a water leak around a brick chimney with counter flashing if installed properly.
Metal Crickets
Custom Welded ~ Most chimneys have a wooden cricket built which separates the water as it flows down the roof. The best way to insure no leaks is to have a custom made cricket sized perfectly for your chimney.   Exact Measurements ~ When measuring a chimney include the slope of the roof and the width of the chimney.
Chimney Cap
Adjustable Size ~ It is best to have a cap put on top of your chimney instead of chicken wire or nothing at all.    

Better to Be Safe
Installed Over the Top ~ Valley Flashing is installed on top of the felt paper but does not guarantee there will never be a leak. The way the shingles are laid over the flashing is most important.   Closed Line Valley ~ Systematic Roofing completes their valley installation by continuing the shingles on the major roof 3' up on the minor roof. Then, overlapping the minor roof shingles, popping a chalk line down the center of the valley and trimming the top layer.


Always Use New
Cut Old J Flashing ~ When replacing an old roof, it is best to remove the old flashing also. This flashing in the picture to the right is called J Flashing. It is made in an L shape with a J loop on one side designed to funnel the water to the bottom of the flashing. It very rarely works in this manner mostly because the roofer has to install the shingles overtop of the flashing. Since the J Flashing is nailed 5" under the siding it is practically impossible to take out so we find that cutting it at the crease is the best way to remove it.    
Tin Shingles ~ The flashing Systematic Roofing likes to use after the old J flashing is removed is called Tin Shingles (step flashing). They can be manipulated and cut to fit precisely into your homes siding creating a virtually impenetrable barrier.   Overlapping ~ The way to install this product is to stuff one end under the siding and the other on top of the shingle. Then, the next shingle will go on top of the flashing and the next tin shingle will go on top etc., etc., etc. Hence the nick-name, Step Flashing.


Lead Jacks
Cut Lead to Fit ~ The lead jack should fold inside the pipe 3/4". If the lead jack is too tall then it should be cut down in size to fit correctly.   Cut Pipe to Fit ~ If the pipe is too tall (whether PVC or Metal) it should be trimmed down so the lead jack can fold inside properly. A regular saw can cut the PVC pipes easily but if the pipe is metal, a larger saw will need to be used.
Steel Vents Hot Water Heater Vents
Utility Vents ~ These are used over the stove exhausts and bathroom fans. If you have a severe problem with squirrels in your neighborhood, you could also use these instead of lead jacks. Squirrels for some reason like to chew on the lead and that creates a leaking hazard in some instances.   Correct Size ~ These are not bought from a roofing supply and are not usually changed unless absolutely needed. A steel vent (shown above) can be used in its place in some instances. The most common way to change these to new is to install a new bottom only and in these cases, the correct size is vital.


Ridge Vents Pan Style Vents
Lomanco OR4 ~ Ridge Vents are by far the most popular ventilation system used today. For best results it is best to cover in the holes left by the turbines or old vents and be sure to check the amount of sophits underneath the eaves. A 1" gap on both sides of the rafter is the minimum size for best results.  

No Motor ~ These are great for garages and in areas where there is no attic (vaulted ceilings etc.).

With Motor ~ These should be installed by a professional because electricity has to be used an is very dangerous.

Turbine Vents
Low Slopes ~ These are mostly used on low sloped roofs and come in 4 different colors.  
Soffit Vents
Intake vs. Outtake ~ There should be the same intake exposed area from underneath as there is outtake exposed area from on top.   Correct Hole Size ~ It is best to measure 10 times and cut once.
Correct Vent ~ There is many different sizes and colors for these vents.    


3-Tab, Z-Ridge or Timber Tex
Flat ~ The 3-tab shingles are cut into three pieces and put on top of each other from the bottom corner of the hip to the top. They lay flat because the 3-tab shingle is very thin.   Thick ~ The raised hip shingles are folded over to give the appearance of a thirty year shingle. These shingles make the roof look like it has an outline.


Algae Resistant
Streaks ~ The streaks on a roof are cause by a pipe or jack oxidizing and killing fungus which grows on the roof. The streak is actually the original color of the roof while the dark around is growing fungus.   Can Be Avoided ~ The ugly streaks can be avoided by installing shingles which have copper-sulfate sprinkled on them. They are more costly then plain shingles but are worth the price.
Chimneys, Jacks etc. ~ A new roof looks better when all of the jacks are painted to match the roof.
