Clay Tile Roof Repair in Miami Springs



This clay tile roof repair we just finished in Miami Springs is typical of the roofing contractor services we provide at Roofer Mike Inc. Clay tile roofs are common in the Miami, Fl. area but present challenges when making repairs. They are dense and therefore brittle so care must be taken when removing and walking on them. Yes, there is a correct way to walk on a tile roof.

Clay Tile Roof In Miami Springs
Tile roof repair with new valley metal
This roof was only 12 years old and the leaks were originating from the valley, indicating workmanship defect. Three types of metal flashing converge at the bottom of this valley – typical – and they must be done correctly or will eventually leak. Flashings should be coated with asphalt primer to ensure adhesion of the underlayment .The flashings must also be set in flashing cement. If regular cement is used it will shrink, dry out, shrink and cause the flashings to fail over time, usually 10-15 years. We use top quality modified cement for all our roof repairs and replacements. Flashings must be nailed down and nails improperly driven or placed incorrectly will cause leaks.
When there are multiple leaks in one valley with so many things possibly gone wrong underneath we always advocate a complete rebuild – rotten wood replaced, new flashings, new valley metal and Tarco PS 200 tile underlayment which is superior to the centuries old hot-mop method. Roof tiles are attached with polyurethane foam which is foolproof compared to mortar.

As with all our roof repairs this job comes with a 3-year warranty, triple the industry standard. How can we do that, you might ask? We don’t mind spending a little extra on quality materials and our repairs are designed to outlast the existing roof.

Typical Flat Roof in Miami, FL.


Flat roof rotten wood replacement
It seems everyone in Miami has a flat roof addition on the back of their home over a master suite, Florida Room or patio area. This flat roof we did in south Miami-Dade was over a back porch and tied into an old concrete tile roof which was done soon after Hurricane Andrew struck South Florida in 1992. I saw some problems with it, most notably exposed 90 lb. underlayment in the valleys. The 90 was crumbly and it’s just a matter of time before water rots out the valley metal and causes leaks – bad leaks. The client had done his own bull & membrane “fix” in two valleys on the front side and planned to do the same to the valley that tied into the flat after we finished. Okay . . .


Miami-Dade tin-cap pattern for flat roofs
There were several leaks near the tie-in and at the perimeter of the flat and it was apparent this roof was another example of the shoddy work that was going on after Andrew. No primed metal at the edges and the tie-in was such a joke that to describe it would risk losing the reader. So we removed two rows of tile at the tie-in so we could just cut that whole mess out of there.
There was plenty of rotten plywood, 3 sheets on a 460’ sq. deck, so much so that we flirted with Miami-Dade’s 25% rule which calls for complete re-sheathing when over 25% needs to be replaced – it was close. Then the entire deck was re-nailed to code. Two plies of GAF Gafglas base sheet were tin-capped to code, a 10” strip applied at the perimeter under 3”x3” 26ga. galvanized drip-edge nailed every 4”oc, which was then primed.                                                                         
Installing concrete roof tiles at the tie-in 
Then we installed a layer of GAF Ruberoid Torch Granule and painted it with Karnak 97 Aluminum Roof Coating (sorry, no pictures of that) to get our fire rating and we were done. Piece of cake, oh – and put back one row of tile at the tie-in. If you get the impression we do a lot of these back yard flat roofs – we do.

Concrete Tile Roof in Miami


We recently finished this concrete tile roof in Miami and it looks great! The old roof was torn off to the deck, there was some rotten wood replaced and the deck was re-nailed to Code. We dried in with 30 lb. felt, tin-capped it to code and installed 16” 26ga galvanized valley metal and drip-edge flashings. As usual, we upgraded - free - the edge flashing to factory white. It costs us about $30 extra to provide this upgrade which gives the finished roof an immediate “pop” and spares the owner the chore of painting it or hiring a painter.

Back-nailing the underlayment 12"oc 

GAF UnderRoof 2 tile roof underlayment was then installed according to GAF specs which includes back-nailing 12"oc and rolling with a 120 lb. roller. We spend a little more on U2 compared to what is popularly used by other roofing companies and feel it is worth the expense – it is simply tougher.
Priming metal for better adhesion

I suggested Entegra Boosted Bella concrete tile in white and the client agreed. The old roof was a 9” flat tile and I thought a high profile barrel tile would give the home a classic look as well as some more dimension, texture. The choice of a white tile should shock no one who has been paying attention as I will always recommend its superior reflectivity which enhances energy efficiency. A white tile will also extend the life of the underlayment and, as a neutral color, goes with almost any home's color scheme.

This house had gutters all the way around and we managed to save them without taking them down. We also removed what seemed like a ton of wet, decomposed leaves which was a real chore in itself.  All in all this concrete tile roof job was fairly straight-forward, other than the gutter rescue, and the customer was well pleased. He was especially with his choice of the whitebarrel tile. Funny, I thought that was my idea. Oh, well . . .
