Matching Discontinued Tile Profiles in Sherman Oaks
What you can check on a tile roof in Sherman Oaks from the ground, from the driveway and the attic.
You can learn a lot about a roof without going anywhere near it, and none of the checks worth doing require climbing. This is what to look at on a tile roof in Sherman Oaks, safely, from the ground.
What you can check yourself
The tile is not what keeps water out. The tile is a rain screen and a sunshade; the underlayment beneath it is the actual waterproofing, and it is the part with the shorter life.
What to leave alone
Stay on the ground and use the attic. Binoculars from the driveway and a torch in the roof space find nearly everything worth finding. Bird stops, eave closures and the mortar at the ridge are what most quotes leave out. Leave them off and you have an open roof edge that invites nesting, debris and, in the fire zones, embers. As soon as you find something you cannot explain, stop looking and get it assessed.
What is specific to Sherman Oaks
Summer is the problem here. Sherman Oaks sits inland at the foot of the mountains with nothing to moderate it, so a roof surface that reads ninety degrees at the coast is well past a hundred and fifty on Foothill by mid-afternoon, and it holds that heat for weeks. Everything on the roof expands into it and contracts again overnight, and that daily movement, not the peak temperature, is what opens laps and backs fasteners out. Much of Sherman Oaks went up between the 1950s and the 1970s, which usually means original decking, ventilation that was never sized for this much heat, and often a layer somebody roofed straight over rather than tearing off.
What we look at on an inspection
- Underlayment age and condition, checked by lifting tile rather than guessing
- Broken, slipped and previously face-nailed tiles across the field
- Batten condition and fixing, particularly at the eave course
- Sherman Oaks metal, which usually corrodes before the underlayment fails
- Ridge and hip mortar or mechanical fixing, and any movement in it
- Bird stops and eave closures, present and intact
- Flashing at walls, chimneys and every penetration through the field
Common questions
What can I check from inside?
A great deal. The attic shows staining, daylight through the deck and ventilation problems long before anything appears on a ceiling.
When do I stop looking and call somebody?
As soon as you find anything you cannot explain, and immediately if there is any sign of water inside.
The honest summary
Judge a tile roof by its underlayment, not its tile. A roof that looks flawless from the driveway can be two winters from a ceiling repair, and the only way to know is to lift a few tiles and look. In Sherman Oaks the thing to watch is attic temperature and intake ventilation, because a Sherman Oaks attic that cannot breathe cooks the underside of the roof as hard as the sun cooks the top.
