When Coating Beats
Tearing Off
Flat and low-slope roofs age differently than pitched ones. The surface takes the full force of the sun all day with no angle to shed it, seams and penetrations open up, and ponding water finds every weakness. When the roof underneath is still fundamentally sound, a silicone coating can reset the clock without the cost and disruption of a tear-off.
Silicone goes on as a liquid and cures into one seamless membrane over the whole surface, sealing seams and flashing details as it goes. It stands up to ponding water better than most coating chemistries, and the bright reflective surface bounces heat instead of soaking it in, which your AC will notice all summer.
Here's the honest part, because this is where some contractors go wrong: a coating is a restoration, not a resurrection. If the roof under it is saturated, if the insulation is wet, or if the deck is failing, coating over it just seals the problem inside. Those roofs need real repair or replacement first, and we'll tell you that to your face instead of selling you a bucket of silicone.
That's why every coating quote starts with us actually walking the roof, checking the substrate, and giving you the same answer we'd give a family member: coat it, repair it first, or replace it.
What a Silicone Coating Job Includes
- Full roof inspection first, including seams, penetrations, and substrate condition
- An honest verdict: coat, repair first, or replace
- Surface preparation and cleaning before any material goes down
- Seams, flashings, and penetrations detailed and reinforced
- Seamless silicone membrane applied across the entire surface
- Photo documentation of the finished roof
Frequently Asked Questions
It depends on the system, the thickness applied, and the condition of the roof underneath, which is exactly why we quote it after walking your roof instead of over the phone. We'll give you a realistic expectation in writing at the estimate.
Often yes, if the existing roof is dry, well-adhered, and structurally sound. That's what the inspection determines. If moisture is trapped in the system, coating over it locks the problem in, and we won't do that to your house.
Generally yes, meaningfully so, because you skip the tear-off and disposal. But cheaper only counts if the roof underneath deserves saving. When it doesn't, we'll show you why and quote the roof you actually need.
