Tile Roof Sealing | Allied Roof Cleaning | Naples, Fort Myers

One of the more popular roofing systems here in SW FL are concrete tile roofs.  Barrel roof tiles also known as Spanish Tiles or Roman Double Tiles are aesthetically very appealing. Tile roofs accommodated on commercial or residential property, with proper installation and care, are popularly known to last between 25-30 years. Many roof tile manufacturers recommend tile roofs to be coated or sealed for added protection as sun exposure is more severe on roof tops. Protect your investment with one of our sealant options.  Both sealant options penetrates the tile roofs’ pores and holds as a part of the substrate. The treated tile roof is super hydrophobic reducing the growth of unsightly mold and mildew for up to 10 years.

Allied now has 3 different sealant options for our customers!

1.  SplashProof:  a solvent based sealant that comes with a 10 year manfuacturer's warranty

2.  Deco 20:  a water based sealant that come with a 3 year manufacturer's warranty

3.  Deco 20 with a maintenance plan come with a 10 year warranty.  The maintenance plan will begin at the start of year 4 and will include visits by our technicians every 2 years.  At the visits the techcian will inspect the roof for any mold and mildew and will clean any spots and reapply Deco 20.  We will also take pictures of any visible damage to the roof tiles and share with the homeowner.

Deco 20

DECO 20 Clear Penetrating Concrete Sealer (DECO 20) is an alternative material replacing bituminous products. It is approved for dampproofing of masonry block, pre-cast and cement roof tiles. DECO 20 clear sealer is a special formulated penetrating sealer designed for the environmental conditions that are found here in SW FL.   DECO 20 clear sealer produces a highly effective breathable moisture barrier, by reducing water vapor transmission.


New & Existing Construction: Dampproofs and seals masonry block, pre-cast and poured concrete walls. DECO 20 clear sealer can be used on the interior of existing concrete and masonry block foundation walls.

Whether the surface in question is concrete or a tile roof, stone, or many other options, Splash Proof can provide a hydrophobic layer which will reduce the growth of mold and mildew for years!

Splash Proof is a nanotechnology coating that is solvent-based or water based, penetrating, V.O.C. compliant water repellent which contains a proprietary modified siloxane. This solvent-based siloxane penetrates up to 1/4 inch or more, depending on surface porosity and moisture content at the time of application. Splash Proof reacts with the minerals in concrete, pavers, and stone. This reaction forms strong permanent bonds beneath the surface and creates a hydrophobic zone that prevents water molecules from penetrating, while allowing free migration of water vapors. The chemical bonds formed in this process allows Splash Proof to become an integral part of the substrate and provide long-term water repellent protection.

Splash Proof water-repellent products create long-lasting protection (up to 15 years) from negative environmental effects. Our products were designed to combat these problems, not only increasing the longevity of treated structures, but also decreasing maintenance costs.

Moisture is the root cause of almost all mechanisms that damage mineral based building materials. The porous nature of mineral substrates soak up the water containing contaminants via capillary suction. This fact causes many damaging effects to the substrate. Preventing water ingress into a substrate structure can completely eliminate risk of damages to the substrate caused by moisture.  The absorb water combine with dirt and spores from plants is a great breeding ground for mold and mildew.  When the surface become hydrophobic or waterproof you essentially eliminate one of the key ingredients in growing mold and mildew…..water.  No water/no mold or mildew.  It’s that simple.

Conventional coatings, like polymeric, prevent water ingress but simultaneously seal off the pores blocking water within. This results in inner decay of the substrate. At the same time they are not resistant to UV radiation or scratches what allows water to penetrate again. You absolutely want the tile to be able to release water vapor from beneath allow the roof to “breath”.

Splash proof is 100% UV resistant. Meaning the harsh Florida sun WILL NOT have any effect on this concrete sealer! That means that your tiles will keep more of their color over the years since the color is not be “baked” out of via the absorption and evaporation of water.  There are many sealants that are produced for concrete sealing, however NONE are geared towards Florida’s VERY HARSH UV exposure caused by our intense Florida sun - making all of the other sealants only last beteen 2-4 years. Our concrete sealer will be backed up with a 10 year hydrophobic warranty on concrete tile roofs, and 5 year warranty on flat work (driveways, sidewalks, parking garages, stair wells, commercial properties etc.) -  and lab testing has shown the concrete sealant to still maintain a water proof nature at the 20 year mark!

Only 1 coat is requred - addtional coats are simply a waste based off the chemical makeup of the sealant. This product is ideal for ALL CONCRETE applications, including commercial sidewalks throughout neighborhood communities and city property, poured concrete typically found on driveways and sidewalks, sea walls, cinder block to waterproof homes and buildings, and concrete tile roof sealing as well.   

Why Spend the Money to get Your Roof Tiles Sealed?

  • It will keep your roof free from mold and mildew for a minimum of 10 years
    • ​Stays nice and clean
    • No more letter from your Home Owners Association mandating that you clean your roof
  • It 100% UV resistent meaning the sun won't impact the bond in the tile. 
  • One of the ways your roof tiles loose their color is from water being absorbed into the tile and then being baked out by the sun.  Since water is not longer being absorbed your roof tiles will keep their color much better than not being coated.
  • Also since water is one of the biggest weaking agent to cement, coating you tiles will help your tiles sustain their strength and durability
  • Not having to have people on your roof cleaning it will safeguard not only your roof but your roof warranty as well that normally lists "roof traffic" as a limiting factor.
