More life from your roof. More time before replacement.
Roof IV assesses aging asphalt shingles and offers a rejuvenation treatment for roofs that are still in suitable condition. Find out whether yours could qualify.
An assessment comes first. Damaged or failing roofs may need repair or replacement.
A clear answer before any treatment.
Roof rejuvenation can be an option when shingles are aging but the roof remains serviceable. We start by checking whether treatment makes sense for your property.
Tell us about your roof
Share your address, approximate roof age and any concerns. Photos help us prepare for the assessment.
Check its condition
We look for signs of wear, missing or damaged shingles, leaks and other factors that may affect suitability.
Apply where suitable
If your roof qualifies, we provide a quote and arrange a professional application with property preparation.
Replacement isn't always the next step.
Shingles age differently. An assessment helps establish whether rejuvenation is worth considering, whether repairs come first, or whether a new roof is the better choice.

Suitability can only be determined after reviewing the roof. Treatment is not a leak repair.
Focused on extending useful roof life.
Roof IV is developing a Calgary based asphalt shingle rejuvenation service. Our approach starts with an honest assessment and a practical recommendation for your roof.
ReActiv8 Inc. is Roof IV’s exclusive roof rejuvenation product partner. The ReActiv8 asphalt shingle formula is plant-based and biodegradable. Treating a suitable existing roof can delay replacement and reduce the shingle waste that would otherwise go to landfill.

What you should know.
What is roof rejuvenation?
It is a treatment applied to suitable aging asphalt shingles with the aim of extending their useful life. We assess the roof first to determine whether treatment is appropriate.
Will it fix a leaking roof?
No. A leak needs diagnosis and repair. Roof rejuvenation should not be used as a substitute for necessary roofing work.
How much does it cost?
Pricing depends on roof size, pitch, access and condition. Request an assessment to discuss a quote for your property.
When can I schedule treatment?
We are collecting assessment requests for the upcoming season. We will discuss timing directly after reviewing your roof.
Does every asphalt roof qualify?
No. Roof condition matters. Severely deteriorated shingles and roofs with significant damage may need repair or replacement instead.
