Expert Verdict — Reviewed by the SuperArbor Pro Desk
No. 90 fiberglass MSR rolls are the go-to economical choice for sheds, porches, and low-slope areas where shingles are not warranted. Match a color to the existing roof when patching or resurfacing, and keep laps generous in ponding-prone areas. Roll out material in the sun briefly to relax it before adhering for a flatter finish.
Take roof fall-protection precautions and handle cut roll edges with gloves, as mineral-granulated roofing can be abrasive.
