Roof Shingle Treatment FAQs
When the shingles’ protective top layer of granule coating begins shedding off into the gutters. This coating functions as a sort of “sunscreen” for your shingles. The oil contained within the shingles is essential for maintaining this coating, but as it dries out, the shingles will start to become brittle and crack.
Black stains and streaking on the shingles is another sign that the roof is aging. Most roofs with staining are shedding the protective top coating to varying degrees. Note: Staining does not harm the roof and is only an aesthetic issue.
Roof Renew proudly warrants that the treated asphalt shingles will perform as originally designed and warranted by the shingle manufacturer for a period of at least five (5) years from the date of your treatment.
The Roof Renew Warranty is still valid even if your manufacturer’s warranty is (or becomes) void due to time or transfer restrictions.
If under normal operating & weather conditions the treated shingles lose their proper operating flexibility, granular adhesion characteristics, or structural integrity or performance, Roof Renew will retreat all affected areas on a simple prorated basis (over 60-month warranty period).
This is not a warranty against leaks, including from faulty installation or other damage sustained by the roof (i.e., hail, high winds).
Testing of Roof Renew's soy-based solution by PRI ASPHALT TECHNOLOGIES, INC., the world's leading independent asphalt testing laboratory, produced the following results:
Flexibility was improved from a Failure to Pass.
Granular Adhesion was improved significantly (by 86%).
Fire Resistance was 60% better than the untreated shingles.
Hail Impact was improved after treatment.
