The Reroofing Process – What to Expect

1. Estimate: When you contact us, we will come to your house, measure and inspect your roof. We will give you a written proposal for the necessary work at that time. We will discuss and explain the proposal with you if you desire.

2. Schedule: Once you decide to use our company, we will schedule a time for your work to be done. We will call 1 to 2 days before the job is scheduled to begin and remind you to make room for material delivery. We will keep you apprised of any changes in the schedule due to inclement weather.

3. Delivery of Materials and Dumpster: The day before the job begins, we will deliver all materials to the site as well as a dumpster to hold all materials removed from the old roof as well as any waste and packaging from the new roof.

4. Roof Removal: On the morning of the job, the crew will begin by spreading tarps around the house to catch all removed materials and protect landscaping and bushes. The crew will then remove all roof materials, felt and nails from the roof decking. The roof decking is then inspected for any damage necessitating repairs.

5. Roof Installation: Once the decking has been inspected and prepared for the new roof, a self-sealing membrane is placed in all valleys and behind the fireplaces. Next, the felt or underlayment is installed on the remainder of the roof decking. Finally the new roofing is installed as well as the necessary roof ventilation and flashing.

6. Cleanup: When the roof installation is complete, the crew will clean up all removed materials, excess materials and packaging. The protective tarps are then removed. The yard is the rolled with magnets to remove any remaining nails.

7. Final Inspection: When all steps are complete, we will walk the roof with the crew and inspect the job to insure that everything is complete and correctly installed. At that time, we will present you with your warranty and paperwork and ask for payment for your new roof. At this time, we remove the dumpster and the work is complete. In most cases, the job takes only one day.

Roofing Requirements

Helpful information everyone should read before having a roof installed!


Decking, which is the sheathing under the roof, is commonly made of plywood or O.S.B. oriented strand board.  Water leaking through a roof may cause the decking to rot.  Because nails hammered into rotten decking will not hold, the rotten decking must be replaced before the new shingles can be installed.  The decking is replaced when the old roof is taken off.  Therefore, a common industry practice is to give a firm estimate on the tear-off/replacement roof, and a firm estimate for each piece of decking which may need to be replaced.


Putting a new roof over an existing roof is a legitimate practice, provided the correct materials are used, all the decking is in good shape, and the truss and house structure can handle the additional weight.  However, tearing off the old roof is the only way to ensure the decking is in good shape.  Since shingles are made of oil, the bottom dry layer of shingles will draw the oil out of the new layer of shingles over time.  This will make the new roof dry out sooner.


Attic ventilation is extremly important to a roofs life.  In the summer, attic temperatures rise dramatically.  Circulating air minimizes the temperature rise.  In the winter, circulating air helps prevent mold and mildew growth by minimizing attic humidity.  The best ventilation system is the ridge vent soffit vent system.  Cooler air enters the attic through the soffit vents.  The heated air then exits throught the ridge vent at the attics highest point.  The ridge vent is preferred by most roofers and shingle manufactuers because they are more efficient and cost effective over power vents, turbines and turtle back vents.

Roof Life

The roofs life is determined by many factors such as proper roof ventilation, proper roof installation, shingle life, and the flashing.  Routine maintenance such as debris removal from the roof and in the valleys, and gutter cleaning are very important.

Clean Up

We use a dumpster that is placed either in the driveway or in the street on the day of the roof installation.  All debris is placed in the dumpster and it is hauled away when the job is complete.


Toeboards are temporary 2×4 boards roofers will stand on while working on steep pitched roofs.  They are not used on shallow pitch roofs.  The nails are put through the shingles in order to hold the boards while working.  If the holes are not properly sealed they will leak.  We do not use toeboards except in tearing the roof off.  We do not put holes in the new shingles.  We normally use a cushion or if steep enough roofing jacks.

Other Information

We nail all our shingles with a coated galvenized roofing nail.  All shingles are layed and nailed to meet the specified patterns for the manufactuers warranty.

A 1 inch nail is used on 25 year 3 tab shingles and 1-1/4 nail is used for 30 year architectural shingle.

We do not use tar to seal roof penetrations, due to the fact it cracks over time.  We use an excellent product called NP-1.

Please Check For Insurance!

Call the insurance company who carries the policy.  A lot of roofing companies will say they have the insurance, but unfortunately they may not.   Roofers insurance is extremely expensive.  Most roofing companies choose not to carry the proper insurance, which would make the homeowner responsible for any injuries or accidents that may occur.

Please take this into consideration when comparing quotes on the items listed above, the type products the roofing companies will use, their labor leak warranties, and if a roofing company is based out of town, who will come fix a leak in a few years.
