Tile roofs can last anywhere from 35 to 50 years, depending on the roofing material installed under the tile. Cracked tile often happen from people walking on them during pressure cleaning or gutter cleaning. Some cracked tiles could even be from the initial installation as inspectors don't usually inspect each tile. There are special adhesives designed to ...

No, it’s not normal for the edges to be loose. Poly glass is a self sealing modified bitumen roofing product. See here: http://www.polyglass.com/public/COM/products/POLYFRESKO_G_SA.pdf As you can see in Item #6 of the installation instructions, the seams are to be lapped 6” and side lapped 4”. I think it’s installed correctly. If there are loose ...

Yes, water on the roof will help cool it. Cooling with liquid water running off from a sprinkler is not efficient, but evaporative cooling from a small amount of water (like a periodic sprinkle) is very efficient. 1 gallon of water consumes 8000 BTU as it evaporates. If you spread 1 gallon of water on the roof once an hour and it evaporates you've made the ...

What you have sounds very much like what we Americans would call a 2" x 8" (nominal size, actual size: 1.5" x 7.5" - yeah, we're weird that way...). What you're proposing is making a 4" x 8" (70x190mm) out of it by nailing the two pieces together. That's not only perfectly acceptable, it's very commonly done for use as a header over a door or window*. ...

Ask the owner to fix the cracked tiles by settlement date. Tiles crack, it is just a part of the maintenance. My house also has tiles and one cracked during a heavy hail. Make sure you check your roof at least once a year or after storm/hail etc.

A major benefit of a grass/turf or otherwise "green plants" or "living" roof is that you don't have the heat of a typical roof in the sunshine. Storm Water management is an additional benefit to the municipality. Both can result in significant financial incentives/tax breaks as a result. "Needing to remove it when you move" ...

Well it depends, many old roofs of this age had 1x boards nailed to the rafters some were later overlaid with plywood But in either case I would feel better about mounting solar on a old roof than one with OSB especially if a coastal area or desert where you get high winds regularly through the year. There are those that only look at the size of the rafters ...

I have used zinc make sure the strip extends beyond the shingles , we started using wide zinc strips at 2 levels after moving to Oregon and noticing no moss or fungus below the metal roof vents. I like black jack it is a good sealant and if putting a roof I accidentally have a shiner a dab of blackjack on top will seal that exposed nail head. Make sure to ...

Attaching joists (2x8 for example) to bigger beams (4x12) so that the bottom of the joist is flush with the bottom of the beam is done all the time. Here's one I did for an indoor project- Should not be any different for your roof deck. Just make sure you use the right fasteners for outdoor use.

Joist hangers are used all the time to fix joists to the side face of the beam. I see no particular reason that you wouldn't be able to hang the joists even with the bottom of the beam using standard joist hangers like these: Picture Source In fact ceiling joists may very well be hung with similar brackets like these where the ceiling height is set to be at ...

No, you have to follow manufacturer’s recommendations for fall. And by the way, fall is discussed as a ratio of rise/run. Nobody uses degrees for that; it’s an unwieldy unit that you have to keep converting in/out of. Build some roofs; you’ll get it. The reason for the fall is simply that an EPDM roof is a membrane. It is glued and sealed, and it could ...

Always follow the manufacturer’s installation instructions. One of the largest roofing companies is Johns Mansfield (JM). There’s many considerations including attachment to roof structure, splicing, fitting around vents, conduit, etc. If you use their accessories, fasteners, etc. it’s more likely that the system will be weathertight. Here’s their product ...

I know that in the USA sliding glass doors can leak if directly exposed to rain, which can be windblown.

Generally not recommended. Trusses are not engineered to carry additional weight on their bottom chords. There are "storage" trusses that can be specified when the house is built that will be able to carry the additional load.

good you're joining the wide sides togher to make a wider rafter, not joining the thin sides to make a taller one. joined they will be about as strong as the wider one. possibly even stronger, because the laminated beam will not have any flaws like knots that pass through the whole thickness. "nail lamination" is a thing, it should be covered in your ...

My answer would be no you cannot. It may depend on your location, maybe not, but a metal roof will allow condensation to form on the underside and that will allow other things to grow like mildew, from the existing growth you have, or keep the other alive too. You will need to clear the old roofing material and lay a condensation barrier down to keep the ...
