Slow gutters, no glory

The kids are back in school and that means summer's over. Autumn is coming and soon we'll be climbing up our roofs and cleaning out the gutters before the fall leaves begin their damage. But how much damage can some leaves really do? Well, in my business, I've seen quite a bit.

I hate coming to what's supposed to be a simple job, then, when I start to work and tear things down, I see tons more work thanks to water damage. Your home's number 1 enemy is water. Why is it the enemy? Because it causes things like mould and rot which compromise the entire structural integrity of the house, not to mention major health problems. That's why we always want water to flow away from our house, from its roof to the foundations. Gutters play an important role in that process. They're supposed to collect the water from your roof and direct it as far away from your home's foundation as possible — I suggest at least 5 feet, but it depends on how close your neighbour's property line is. Seems simple, but there are a few things that can get in the way of gutters doing their job.

Many of the newer homes being built have more than just a single roof. For example, there could be a roof over the garage, one over the second floor of the house, and smaller ones over rooms that extend from the house, such as a kitchen area or mud room. No matter what, there should be an eavestrough running along the bottom of every roofline on a house. Every eavestrough needs to have a downspout that drains the collected water away from the roof. You never want a downspout to drain water directly onto a lower level roof, this will cause water and ice damage to the shingles and roof deck underneath. It must always drain into a lower roof's eavestrough. You also never want a downspout to drain directly into the weeping tiles below ground or near the foundation, this causes water damage to the foundation. In either case, the result is water coming into the house at the roof or foundation level. Not a good thing.

Some people think gutters can be a DIY project. Most DIY gutters are plastic and come in standard sections of about 10 to 12 feet. Plastic gets brittle, especially in the cold, and will need to be replaced. That's why aluminum is the industry standard for gutters. It never rusts, unlike steel, and it's weather resistant, unlike plastic. We also want to use a thick gauge for all metal gutters. The thicker the gauge the longer they'll last. When gutters are built in sections there's going to be seams and seams can leak. And believe me, if it can leak, it will. That's why I only recommend seamless eavestroughs.

Professionals use a forming machine to construct seamless eavestroughs — custom sized to fit the length of any roof. It's the only way an eavestrough should be done and it's the only way to prevent leaks. Professionals also make sure the entire eavestroughs is pitched correctly. Otherwise, water is going to gather and it won't drain properly. You want something that's going to last. You don't want something you'll have to replace after the first winter. Doing it right the first time means we don't have to do it again. You always need to bring in the right people for the right job, so get a professional to install your gutters.

Before the temperature drops below freezing our gutters need to be clear of any debris. If our eavestroughs and downspouts are clogged two things will happen: First, any debris and water caught in the eavestrough will freeze into a channel of frozen muck. This will overload the eavestrough and eventually it will warp (remember, water expands as it freezes).

Secondly, water can back up under the shingles and cause ice damming and water damage to the roof deck. I know it's a pain to go up there and clean out the gutters, so some people put it off for as long as possible. Not a good idea if you want to preserve the integrity of your roof. A good way to prevent clogging is by installing a screen guard that sits over the eavestrough. This prevents any leaves or debris to fall in. It also eliminates the chore of you having to clean your gutters. There are a few screen guard products out there you can purchase and install yourself. Just remember to brush off any leaves that can get stuck on the screen so they don't block the screen's holes and prevent proper draining.

I've heard some complaints about ice damming after installing a screen over eavestroughs. Let me clear this up: The screen isn't causing ice damming, it's heat loss from the home that's causing it. You know those icicles that hang off the gutters in the winter? A lot of people seem to like them, but icicles are created when snow melts, and then the water refreezes before it drains through the eavestroughs. How can the snow on our roofs be melting if the temperature outdoors is below freezing? That's because heat is escaping from the roof and melting the snow. So if we want to prevent ice damming we need to think about insulating our attics better and double-checking our roofs for any potential heat loss.

Hardware features

The RBM HD comes equipped with one of the Snapdragon family of system on chip – a Qualcomm MSM 7230 chipset featuring a 45nm 800MHz Scorpion processor, an Adreno 205 GPU and 512MB RAM. In terms of performance, this hardware setup is not too shabby at all. Impressively, our benchmarking results pegged the entire system on chip combination as a rather highly rated device - slightly ahead of the Motorola Droid (Android 2.2+), and just behind the Google Nexus One (Android 2.2+) in terms of system on chip performance.

The device supports HSDPA 900 / 2100 with a downlink speed of up to 7.2 Mbps. Coupled with the full range of 2G GSM support, this means the phone isn’t locked to a particular network.

The 5-megapixel camera does an admirable job of taking photographs, but does suffer in low light conditions (as do most cellphone cameras). The LED flash didn't compensate too well in low light scenarios, occassionally washing out the image rather than illuminating the scene. This is a fairly average performance for a cellphone camera.

The camera can also record video at 720p and the Qualcomm MSM 7230 chipset is handily capable of playing this back at that resolution on the 480x800 resolution screen.

Most of the other bells and whistles you’d expect are in place, such as Bluetooth, an accelerometer, ambient light sensor, proximity sensor, ambient noise reduction and GPS. Internal storage of 4GB combined with a microSD slot (up to 32GB) should provide enough space for most purposes.

The battery lasts a long time in standby mode, and we can fully believe the manufacturers claims of 380 hours. Of course, no one buys a phone to leave it in standby, and in practice the RBM HD exhibits typical smartphone tendencies of a full charge lasting for just about a day’s worth of average to heavy use, before needing a night-time charging.

Call quality was adequate, with the earpiece, microphone and noise cancellation appearing to work in admirable harmony. The rear loudspeaker sounded rather weak, however. It’s not terrible, but it certainly could have been louder and better.

All in all, the RBM HD features fairly standard hardware among current Android devices, with nothing to really complain about, nor make a fuss of.

Screen

The screen is also fairly standard kit for a modern high-end smartphone - a 3.8-inch, 480x800 resolution, 16M colours, TFT LCD with a capacitive touch-sensitive layer. This means it can take advantage of multi-touch user input schemes and is generally more sensitive than the now outmoded resistive touch-screen. Of course, this is not a Super AMOLED or ‘Retina Display’ but it does the job.

At 245.51 PPI images appear to be sharp enough, but of course pixellation also depends on the user’s eyesight. Most should find the screen to be colourful, bright, sharp and responsive – good enough for prolonged periods of browsing, reading and viewing.

Software

One of the attractions of the RBM HD is that it comes with the vanilla Android 2.2.1 (FroYo) operating system. Thankfully, Red Bull Mobile branding didn’t extend to a custom user interface (UI). The standard Android FroYo UI is functional and intuitive - there are no complaints here.

RBM did include a bunch of ‘value add’ apps. The Red Bull Mobile portal is a fairly typical content portal with a Red Bull flavour - free wallpapers, videos, music, news, and access to the streaming Red Bull TV. There is also Red Bull Radio, an exercise coach, and a Red Bull Flugtag game. I make mention of these (possibly) innocuous apps because they are annoyingly irremovable. Of course, where there’s and Android user with a will, there’s a way…
