When it's time for a new roof installation, you may have a lot of questions for your roofer if you've never been through the process of getting a new roof before. Your roofer will take time to explain the process when they provide you with a price quote, but here are a few things to know about getting a new roof.

1. The Roofer May Replace The Entire Roof System

After the roofer inspects the shingles and deck, they'll let you know how they intend to proceed with putting on your new roof. You may also get some input on replacing parts like the flashing that are still in good shape.

A new roof installation usually consists of new shingles and new underlayment. You might need part or all of the deck replaced too, depending on if it has damage. The roofer might automatically replace the metal flashing as well, but since it's made of metal, it may be in good enough shape to stay on your roof for several more years. All the parts to be replaced should be included in your estimate so you know exactly what you're paying for.

2. You May Notice A Loss Of Granules At First

If you've heard granule loss is bad for an asphalt shingle roof, you may be alarmed when you notice your new roof shedding granules. This is common with a new roof installation. Your roof loses a lot of granules at first, but the loss slows down as your roof settles in.

Another alarming thing you may notice about your new roof is that the shingles have a bumpy or wavy look about them. This is usually due to the adhesive strip under the shingles. The adhesive gradually warms up and gets soft so the shingles stick together. Your shingles will eventually be flat, and the wavy appearance will clear up once the adhesive bonds.

3. Rain May Not Be A Serious Issue

Your roofer tries to work around rain since being on a roof when it's rainy or stormy is dangerous. If rain is possible on the days your new roof installation is scheduled, the roofer may tear off and install your new roof in sections so your home doesn't get caught in the rain without roofing on the deck.

However, the first thing to go down when the old shingles come off is waterproof underlayment. So, if there is surprise rain, your roof deck will be protected as long as the underlayment is down. Once the underlayment is dry, the new roof installation can go on as planned.
