Delaware Roof Pros provides professional roof coatings & sealing in Delaware, OH for residential and commercial properties across Delaware County and the Olentangy corridor. This page argues against its own product on about half the roofs it gets asked about, so we may as well start there. We do not coat steep-slope asphalt shingle roofs. Not for any price, and not as a means of buying a few more years out of one.
The reason is substrate, not opinion. Coating manufacturers write their own data sheets to require a sound, clean, dimensionally stable surface, and a granular shingle field is none of those three things. The coating bridges the granules rather than bonding to the mat, and it goes on with a roller over a surface designed to shed water in overlapping courses instead of as a monolithic skin.
When that fails, and it does, it fails as a sheet. Moisture gets trapped underneath, the shingle beneath it cannot dry, and whatever remained of the manufacturer's warranty goes out with it. You have then spent real money making the eventual tear-off harder and more expensive than it would have been. That is the entire argument and we have never found a version of the job that survives it.
Where coatings genuinely belong here is on metal and modified bitumen. A shop roof, a warehouse deck, an agricultural building with sound panels and hardened washers, a low-slope modified roof with a few years left in the membrane. On those a silicone restoration system is a real answer with a real service life, and it can be applied without shutting the building down for a week.
The testing comes before the quote, not after it. Adhesion pulls on the actual substrate, a moisture survey through the insulation, and an honest look at whether the deck below is dry. A coating over wet insulation seals the water in and buys you a more expensive tear-off later, so if the survey comes back wet we take the coating off the table rather than sell it anyway and warrant the surface.
Seams and fasteners get treated separately and first. Most metal roof leaks are seam and fastener leaks, and a full field coat spread over unaddressed penetrations is money distributed thinly across a problem that was concentrated in a few square feet. Coating warranties are worth reading closely too, because most are material-only and prorated, and the labor to reapply is the expensive half of the bargain.
Our licensed and insured team brings the right materials and equipment to every job — ASTM D1970 ice barrier membrane, step flashing woven at sidewalls, counterflashing folded into a ground-in reglet, synthetic underlayment printed with fastener grids, ASTM D3161 Class F seal strips, H-clipped 7/16-inch OSB decking — and backs the work with a written workmanship warranty. We serve Delaware and nearby communities including Powell, Sunbury, Galena, Ashley.

Materials, equipment and how we do roof coatings & sealing
The difference between roof coatings & sealing that lasts and roof coatings & sealing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with ASTM D1970 ice barrier membrane, step flashing woven at sidewalls, counterflashing folded into a ground-in reglet, synthetic underlayment printed with fastener grids, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Delaware job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in Delaware County and the Olentangy corridor means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
