Collect a Roofing Sample
Please read all directions before removing roofing. Keep safety in mind when collecting the samples; be careful around sharp tools and edges. If you have safety concerns, you can ask that your roofing contractor collect the sample for you.

For All Roofing Samples
Collect a full height and length section of the sample. If a full piece is not available, make sure to note dimensions on the form submitted with the sample, and include a partial piece of the roofing for analysis. For asphalt the piece should include at least one and a half tabs.
Removing Asphalt Roofing
- Locate the shingle you intend to submit to ITEL. Do not collect the shingles closest to the edge ("starter" shingles), as they may be a different product from the other roofing. Use a pry bar or putty knife to gently pry away the nails on the shingles surrounding the target shingle.
- Use the pry bar to loosen the adhesive seal strip along the entire length of the target shingle. The handle of a hammer can be used for additional leverage if needed.
- Once the surrounding shingles are completely separated and the adhesive seal has been loosened, gently rock the target shingle back and forth to remove it.
- If moisture is a concern at the site of the removed shingle, a plastic sheet can be inserted under the remaining shingles. Tack the sheet in place by nailing through the shingles into the top of the plastic. Also secure the sides and bottom of the plastic.
