Prevent leaks and water intrusion.
Stop mold, mildew, and moisture damage.
Extend roof lifespan.
Reduce repair costs.
Improve home and building value.

FAQs (People Also Ask)

Most waterproofing costs between $1.50 to $6.00 per sq. ft., depending on roof size and materials. Some roofs need repairs before sealing, which may increase cost.
For most roofs, silicone coating and elastomeric waterproofing work best. For commercial or flat roofs, EPDM, TPO, and Bitumen membranes provide long-term protection.
Fix cracks and broken areas, seal flashing points, repair damaged shingles or tiles, and apply a strong waterproof membrane or coating. Professional waterproofing gives the most permanent results.
Basic acrylic waterproof coatings are usually the cheapest option. They work well for short-term protection but may need reapplication sooner than silicone or membrane systems.
