The sheathing under a composition shingle roof will typically be plywood or 6” or 8” lumber creating a solid deck as depicted in the above photo. You can usually look up inside of your garage to find out why type of sheathing or roof decking your house has (if there is not dry wall on the ceiling). Sometimes a composition shingle roof may have one, two, or three layers of roofing that should all be removed. New guidelines, codes, and regulations call for all layers to be removed down to decking.
There are two main types of pipes that penetrate through your roof:
1. Plumbing roof flashings are the ones without top flashings (see photo below). The metal flashing around the pipe keeps water from leaking inside the house. These pipes allow air into your sinks or toilets pipe lines. Colorado Pro Roofing installs all new pipe flashing and paints them to match or compliment your roof color. The area between the new flashing and your pipe is sealed with a lifetime rubber collar to keep out all rain water. Other contractors use tape or caulking to seal, which can un-ravel or separate. Attention to details like this means decades of maintenance free protection for you.
Materials are loaded and stacked on roof top.
All roofing debris is tossed into our dump truck and hauled way. Average tear off time is ½ day. The truck drives off takes it to a recycling facility. We do not leave dumpster sitting in your driveway for a week like some contractors do.
We even use a nail magnet to find hidden nails in your grass, shrubs, walkways & driveway.
A great way to show us you appreciate our hard work is to allow us to put up a company sign in your yard. This helps us keep our advertising costs down.
We use heavy duty 30lb ASTM roofing felt on all of our roofing jobs. Watch out, others may only be using 15lb felt. Roofing felt (or tar paper) contains waterproof asphalt which is the second barrier for your roof. Felt also seals around the nails when your shingles are installed. Over time felt will dry out and when your felt dries out it loses its waterproofing capability. 15lb felt will dry out much faster than 30lb felt. Do you want longevity in a roofing system? You’ll want to have 30lb roofing felt correctly installed.
Dry rot is caused by a fungus which continues to spread until treated or removed.
Correct installation is vital here. Many contractors just install OSB the easiest way. We install it the correct way as specified by the (APA) American Plywood Association.
To re-roof your house correctly, you’ll want to have your old chimney flashing completely replaced. Many contractors just reuse your old flashing. We replace your chimney top saddle, bottom saddle, step shingles, and counter flashing. The counter flashing is sealed and all the new flashing are painted to blend in with your new roof. This is the best and least expensive time to have your chimney flashing replaced and it ensures a complete water-tight roof system.
Repair costs, if any, are only about one fourth of what they would be with the roof on. If any repairs are necessary a change order will be written and we will obtain your approval before proceeding.
A Colorado Pro Roofing estimator will provide a complete written estimate with at least 5 roof types or grades to choose from. We will also show you samples and give you brochures and explain the advantages and disadvantage of each roof or shingle type. Then you decide what type of roof you like and can afford.
Colorado Pro Roofing installs most residential roofing products including:
1. Composition shingles, Asphalt, or Fiberglass (3 different names for the same product).
2. Lightweight title.
3. Metal Roofing panels and/or Decra metal roofing system
4. Modified Bitumen (for flat or low-sloped roofs).
By far, the most important part of your new roof is not the shingle you choose, but the contractor you choose to hire. Most shingles today have a 30 year to a lifetime manufacturers warranty. But if they are not installed correctly you will not have any warranty at all.
How often are shingles installed incorrectly? After over 23 years of roof inspections performed for real estate agents, we estimate 7 out of 10 shingle roofs are incorrectly installed. Most commonly, they are not correctly nailed. Themanufactures specification state “all nails must hit the nail line.” The nail line is the thin white line near the middle of the shingle. Many contractors for years have been nailing an inch or more above the nail line.
By using 6 nails per shingle it increases the wind endurance by 50% and can withstand wind speeds up to 120 mph.
Inspect for dry rot & termite damage before roofing
More water runs down your valleys than any other place of your roof. Valley flashing are either 18” or 24” wide depending on the type of roof you have. Shingles are installed over the valley flashing and then cut short of the center line creating an open center for water to run down. Most contractors buy galvanized valley flashing then spray paint them to match the shingles. Look at these same roofs a year later and the paint will be already flaking off. Colorado Pro Roofing buys valleys pre-painted in a complementary color to your roofing shingles. Our valleys have factory baked-on enamel paint. This difference is longevity and is virtually maintenance free. You will never have flaking paint with our valleys.
If you have a wood shake roof, our crew tears it off right down to the sheathing. The above photo shows a shake roof with spaced or skip sheathing. This is the construction normally found under a wood shake roof.
If your roof was wood shake and you want a composition shingle roof, you will need to have solid roof deck installed first. We recommend installing 7/16” OSB (Oriented Strand Board) over all spaced sheathing. It’s what you see on almost all new construction. OSB has the same exterior ratings as plywood but cost less, without any sacrifice in quality. OSB’s 16 layers make it stiffer and more impervious to termites than 3 layer plywood.
These are the basic steps involved in replacing your old roof with a brand new roof by Colorado Pro Roofing & Restoration Services LLC. It’s not so much what we do, but rather how we do it that makes the difference.
We also recommend that skylight flashing be replaced during the re-roof to ensure a leak-free system.
Colorado requires a permit to roof your home. Some contractors do not secure permits. We do. This protects you by having a 3rd-party city inspector independently check your roof. Colorado Pro Roofing will apply for, obtain, and post the re-roof permit for your project. After the city inspector has signed the final inspection, we will give it to you to keep for your records. When you sell your house you will need full disclosure of what was done with or without permits.
2. The roof flashings with tops (see photo below) are usually from the furnace, water heater, and bathroom and kitchen exhaust fans. These are also painted to match or compliment your roof color.
The best, most efficient way to add exhaust ventilation is by adding a ridge vent system. The photos below show how we build it: We cut a ¾” slot down each side of the ridge beam. Felt and shingle up, and put a special type of a ridge system that keeps out the rain and allows hot air to exhaust out.
Most houses have adequate intake ventilation through eve screens but lack adequate exhaust ventilation. Some of the traditional intake and exhaust methods are shown below.
Metal 2” x 2” flashing is installed around the perimeter of the roof. It covers the exposed edge of the OSB and keeps it watertight. It's factory painted with baked-on enamel paint, just like our valley metal.
The problem? Most shingles are actually two pieces laminated together. The nail line is where the two pieces overlap. If you miss the nail line, the nail will be fastened through and holding only one layer instead of two. In wind, shingles nailed on the nail line through both layers will have more than twice the holding power than those that miss the nail line. The photo on the right shows a real life example of the common problem of high nailing.
Can you inspect for high nailing? When your roof is completed there are no nails visible. The next course covers up the previous shingle course. It’s not practical to lift the shingles up after they are installed to check the nailing because the seal strip under the shingle might break if the shingle is lifted up. This is why hiring a competent and trustworthy contractor, even if it costs a little more, is money very well spent and is the most important part of your new roof. It is much more important than even the price you pay. Because if it’s not installed correctly, you risk the chance of losing everything and you might have to even replace your brand new roof. It’s not worth the risk hiring the low bidder. It is better to hire a quality contractor the first time.
Colorado Pro Roofing installs a truly professional roof. Not only will it be nailed correctly, but you will see straight shingle courses, straight valleys and straight trim and ridge, just like you would expect. This is easy to say, but hard to do. It takes a professional that really cares about their work to produce a quality roofing system.
We install a 1/8” gap around each sheet of OSB for expansion and contraction. Yes, this is required. Yes, this takes longer to install, which is why some contractors don’t bother. Do you want to have a great roof installed? You need to have a great foundation; an OSB roof deck installed the right way!
After the tear off, we inspect all sheathing to make sure there is no dry rot or termite damage. Since dry rot starts on the top of the sheathing no one can give you an accurate estimate of dry rot damage until after the roof is removed.
The parts that we use on your roof are called “system components”. They are roofing parts that are made to work together and produce a superior roofing system. GAF Pro-Starter Strip, for example, is installed around the entire perimeter of the roof. Most contractors will just use the cheapest starter they can find. Colorado Pro Roofing uses Pro-Starter Strip because of its superior performance. Pro-starter Strip contains a “Dura Grip” adhesive sealing strip that seals itself to the shingles installed on top of it. This makes the entire perimeter of your roof much stronger. This is very important because when strong winds hit your roof, the uplift is strongest on the roof perimeter. It works, even in gale force winds. That’s why we use the manufacturers made Pro-Starter Strip. It’s a critical component of your roofing system.
The two photos above show completed eave repairs made to the sheathing (8” V-rustic).
Colorado Pro Roofing will clean the roof off, clean your gutters and clean the grounds.
The OSB is fastened every 6” on the rafter ends of the OSB and every 12” over the interior rafters. Each sheet is off-set from the previous course (full sheet, then half sheet). This off-set makes your house much stronger. If the top or bottom long edge of the OSB does not land on the spaced sheathing below, we add a 1”x 3” support. This keeps the OSB from dipping down on one side when stepped on. It prevents future tears on the underside of your shingles where you can’t see the damage, making your new roof last longer
Proper attic ventilation is important and now all major shingle manufacturers require proper attic ventilation as part of their shingle warranty. Without proper attic ventilation, your shingles will get too hot, which will shorten the life span of your shingles, and cause your house to get too hot inside during the summer.
Proper attic ventilation has two components: Intake and Exhaust. Cooler air enters the attic space through your eave vents. As this air warms up, it rises. Hot air needs a place to escape or exhaust, so it doesn’t super heat your house during the summer. Exhaust ventilation near the peak of the roof (at the ridge) is ideal.
