Frequently Asked Questions

I want to hire Sentry Roofing, what do I do?

Congratulations, you made the best choice! The next step is to call us and set up an appointment for us to come do a free estimate and we will provide you with a comprehensive proposal.

How will I know when my installation will be?

We try to accommodate everyone’s schedule when we schedule a roof replacement. During your scheduling process please let us know when the best time for your installation is/ You will receive a call or email 1-3 days prior to your installation letting you know what day we are planning on starting as well as when your materials will arrive.

What time will the crew arrive?

Our crews start early in the morning. They generally arrive between 7-8am. After tarping the house, it will get a little loud as the old shingles begin being torn off the house. Some small animals get a little nervous, but in our experience, they settle down soon thereafter.

Do I need to be home during my installation?

No, you do not need to be home! Most homeowners are busy rushing the kids out of the house for school and then off to work in the morning. The only thing we may need is a source of power. If you have an outdoor outlet, just double check it works! Otherwise, if you can leave an extension cord out a window or under the garage door that we can connect to, we will be good.

What time will they finish?

Most jobs are completed within 1-2 days. In the summer, when the days are long, it is not abnormal for the crew to stay until nearly 8pm to complete your installation and make sure the clean-up is perfect.

Do I need to remove things from my porch/yard?

The crew will move anything that may be in the way and put in a safe place while your installation is in process. It’s not a bad idea to remove anything fragile or valuable from your interior walls as the walls sometimes shake slightly during the installation process. You may also want to cover any valuables in your attic as (depending on type of construction) some shingle debris and dust can fall through the cracks and end up in your attic.

Where will the dumpster be placed and when will it be removed?

The dumpster normally arrives the day before, or morning of the installation and is placed in your yard or driveway. Our skilled dumpster truck drivers will find the best place that works for both you and the crew. The dumpster is generally removed from the jobsite one business day after the job is completed.

There is material left over, does that mean I over paid?

No, we always try to send a little extra material to every job. Some roofs have a higher “waste” factor then others and determining the exact waste factor is sometimes tricky. We prefer to have plenty of material on site and ready to be used rather than running around at the end of the day.

The job is complete, how/when do I pay?

Once the job is complete you will get an invoice from the office manager. There will be full payment instructions as well as a chance to leave a review! You do not need to give a check to the installers unless you prefer to do so.

Some shingles look like they are sticking up a little, is this normal?

Yes, this is absolutely normal. It can take several days, even weeks depending on the temperature, for the shingles to soften and “sit.” You will notice your roof changing each day after your installation until all the shingles have sat down and adhered. If after all this time, something still doesn’t look right, just give us a call and we will be right out to check on it!
