I have a Tile Roof with no sheathing or underlayment! What should I do?

This is how tile roofing was done before felt paper was invented and arguably a great way of installing tile. 1) You know you have a leak instantly. 2) so there is very little dry-rot if every any. 3) the attic breathes really well. 4) it actually works. It’s worked for thousands of years. 5) It’s very very easy to repair. Slide out the old tile and slide in a new one. No felt to repair. 6) This installation is usually only decorative on rear patios by pools where no living space is under these tiles. This is because this application is no longer code in the Tile Roof Institute Installation Manual. This is the ancient way of installing tiles. However, I wanted to give the ancient craftsmen their due for the genius of the application that was around for thousands of years.
Downsides: 1) It leaks instantly. Felt paper does offer a secondary protection. However, felt can conceal a hidden leak for years. 2) It does not have plywood shear on the roof. In areas that experience earthquakes… that shear is a big deal. 3) It allows animal intrusion. I’ve seen attics infested with bats, squirrels and rodents as it’s easy to just walk into the attic. 4) It’s not in accordance with Tile Roof Institute installation manual or any local building codes any longer. So, this means you wont have a warranty with this application.
If you decide to re-roof your home that has this application you may wish to consider a few things:
- Consider sheathing with Radiant Barrier OSB. The Radiant Barrier OSB upgrade is minimal, and even if it does not work at 100% efficiency due to the skipped sheathing boards it still works and will help the energy efficiency of the home.
- Calculate your ventilation. Many times the builder did not install intake soffit vents because the intake ventilation came in through the eave tiles. If you close up the roof with sheathing then you are also closing off your intake ventilation. You’ll need to add soffit eave ventilation to compensate. Make sure enough ventilation is installed high in the roof to properly exhaust the roof.
- Install a self-adhered underlayment on the eaves. Wind blown rain tends to affect tile most on the eaves where the tile meets the gutter or drip edge.
- Consider installing a rake metal on the rakes. One major weakness with tile is the rakes where wind blown rain can force water under the rakes and rot the gable end rafters.
- Consider increasing the overlap on the tile. Most tiles are installed with a minimum 3″ overlap. Consider going old school and install he tiles with a 4″ minimum overlap. It only adds about 10% more tile to the roof. You may need to consult with a structural engineer – but it’s worth it if your structure can handle it.
- Use 5 crown valley metal and side wall metal with a crown or rib.
- Oversize your flashings. Do not use comp flashings on a tile roof. Use custom oversized flashings for hvac and plumbing pipe penetrations.
- Maintain your roof after it’s done. Get it inspected every few years for wind/hail or damage from freeze/thaw and other construction traffic.

What can I do if I have a roof leak?
What you can do on the inside of your home:
- Don’t panic.
- Get a bucket or plastic container for the water to drip into.
- Place towels around to soak up any water so it does not damage your interior.
- If the ceiling is bulging or bubbling – safely poke an approximately dime sized hole in the sheet rock at the center of the leaking area to drain the water. It’s easier to repair a small hole than to fix a ceiling collapse. If the water accumulates it will drop sections of the ceiling. In very large roof leaks this may happen anyway. So, if the leak is very large, safely move things away from the leak.
- If a roof leak is in a bedroom with children or other occupants, it is recommended that they be moved out of the room.
- Document the roof leak with photos and or videos for your insurance company.
NOTE: Be careful about getting on the roof or accessing the attic yourself. Climbing ladders, walking in attics or on roofs are some of the more dangerous and deadly occupations even for professionals.
Information your Roofer needs:
- Where is the leak? Is it on the first floor or on the second floor? Is it on a wall or in the middle of the room? What room is it in and where in the house is that room?
- How major is the leak? Is it a major leak or just some dripping? Is it leaking inside or outside in the overhangs, in a garage, or porch?
- What kind of Roof do you have? Is it an asphalt shingle roof? Is it a concrete tile roof? If you take a photo of the roof from the front or back yard – many times it helps your roofer determine what type of material your roof is. This may save you time & money. For example, if your roof leak is a real clay roof tile there are many roofers who do not work with that material. Some roofers will not even walk on some roof tiles. If you have asphalt shingle a roofer may have some similar shingles in his yard and may be able to bring the correct materials with them. If you can have the roof leak stopped, repaired, or mitigated on the initial inspection it may save you a tarp fee.
What do tarp’s cost?
- In general a tarp is the cost of the materials, time and gas to drive to the property and time to install the tarp. Remember, that roofing has some of the highest insurance costs in the industry.
- Many roofers do not tarp alone, because usually when your roof is leaking the weather consists of wind and rain. Large tarps may be impossible to install alone in some conditions. With that being said roofers have their own minimum charges to install a tarp. Also, if you need your whole house tarped it is a considerable effort and expense. Tarping around flashings, chimneys, and skylights is extremely dangerous and is generally avoided if possible. Some roof lines due to the architecture, steep slope, or low slope may be impossible to properly tarp.
- Tarps are not a roof, and may not fully stop a roof leak. They also are not made to stand up to heavy wind gusts or pouring rain storms, etc.
Tip: Many roofers will offer you a discount off the tarp fee if you use them for a re-roof or repair.
After your roof leak is inspected, tarped, mitigated, etc., you will probably need some roof repairs.
What are the most common causes of roof leaks?
- Flashings. The flashing is too small, or the material is wrong for the application, or the flashing is in the valley or below the valley. The flashing is rusted or parts of the flashings are not sealed, or the flashing is full of debris. Also, certain weather seals need to be replaced from time to time like rubber collars, or the sealant in the skylight lid.
- Missing or broken tiles or shingles. Lots of roofers will repair tiles by gluing them together. This doesn’t work and allows water intrusion. Roof tiles need to be replaced. Shingles that are blown away need to be replaced with new shingles. (usually you need to hand tab these down)
- Debris on the roof. Debris causes water dams. The water cannot flow off the roof and goes side ways under tiles or shingles or even up hill! Contrary to popular belief… underlayment is not the real roof in 99.9% of applications. Water getting on your underlayment regularly will rot the underlayment and cause damages and or leaks. (Picture of debris on a roof)
- The roof is bad. The roof may be in need of a re-roof or it’s done wrong and needs a re-roof.
Reminder: All roofs need Maintenance and Cleaning from time to time. Schedule a Maintenance inspection with a Licensed and Insured Roof Contractor.
