  • Owner was proactive and sought out the AcryPly Restoration System to avoid a costly, disruptive roof tear-off and re-roofing project.

  • The AcryPly Restoration System provided this apartment complex with a fully restored roof top using polyester reinforcing fabric across the entire substrate for additional strength and durability.

  • Difficult roof design was easily sealed and restored with the spray applied application of the coating system to create a seamless, monolithic, watertight roof membrane without all the noise of traditional roofing.     

This roof had thousands of lineal feet of details. Hundreds of feet that was curved, circular, transitions from flat to vertical, pipes, curbs, vents, expansion joints…. no problems. It’s an awesome project and the ACS crews absolutely ROCKED this one,” said Dan Varvais, National Coatings’ Product and Technical Manager.

Top 6 Roofing Issues that Need Attention Immediately

What to look for... These top 6 roofing issues need attention immediately

The following 6 issues are the most common roof failures that can occur to roof tops if not properly checked on or maintained. By avoiding these issues, an expensive roof repair project could be in the near future. Check out our article "Can My Roof Benefit from a Roof Maintenance System?"

1.Ponded Waterimg_0185

Ponded water leads to delimitation, blistering, peeling and compromised adhesion of the roof system to the buildings substrate. This issue needs to be fixed immediately. To remedy ponded water, the AcryShield SPF Roofing System allows you to create a custom slope in areas where ponded water typically occurs, allowing the standing water to flow towards proper drainage.

2. Impacted or Clogged Drainage


A plumber is recommended to unclog the drain and then the ponded water needs to be inspected to make sure no further damage has occurred. (See Ponded Water above more information.)

3. Blisters


Blisters occur because of several reasons, including: adhesion issues, ponded water, an aging membrane and more. This is another issue that needs to be fixed immediately as water penetration is likely. Contact a Roofing Professional with zero obligation to determine your next steps to restoring your current roof.

4. Debris from Overhanging Trees


It is necessary to cut back branches that hang over the roof top because they can cause abrasions to the surface of the roof and leaves and branches can clog drains and create ponded water issues. It is important to ensure the roof is clean and free from any debris.

5. Mastic Cracking at Pipe Jack


When seals are failing and not functioning as designed, water penetration can occur. All joints and flashings need to be inspected to ensure seals have good flexibility (not brittle), adhesion, and water resistance.

6. Plant Growth


Weeds, trees, and plants can grow out of the smallest cracks on your roof. Carefully remove any form of plant growth immediately as this can cause several issues including: improper drainage, damage from roots, inadequate adhesion, ponded water, etc… Do not pull or yank the plant from the roof as the roots may have penetrated through the surface and this could cause even more damage. Contact a roofing professional if you think this could be the case for your roof.
