How Do You Attach a Flat Roof to a Shingle Roof?
The simplicity and versatility of flat roofs are turning them into a popular choice for residential roofing projects. Flat surfaces are found on tiny homes built in urban centers or rural off-grid locations and new additions to existing pitched roofs, including garages, porches, and garden features such as the pergola and gazebo. When tying an additional level onto your home with a flat roof, it will take some work to ensure everything stays watertight! Here are the steps on attaching a flat roof to a shingle roof:
First, install a starter course of wood for the underside of your new flat roof. Then layout sixteen strips of flashing metal on top, with an equal number on both sides and end pieces at either edge. These are called “flashing fasteners” and should be spaced about two inches apart. Next, attach the flashing to the underlayment using small galvanized nails or screws per manufacturer’s instructions–usually four across from one side piece to another and twelve along each long strip. Position them every six inches as you go around your building perimeter edges until all 16 pieces have been secured in place by nailing or screwing into studs behind sheathing boards. Once finished, try walking up onto it to see if it feels sturdy.
What Do You Put Under Rubber Roofing?
There are many reasons why roof membranes can be a great investment. With the right product, you will have protection from significant damage and possible repair costs! If your budget is tight, an underlayment might be enough to keep the elements at bay until you can afford that new roof. However, if finances allow and there’s a concern about rot setting in from rain damage, it’s worth considering using both as insurance against costly repairs down the line.
It doesn’t take long before wet weather starts going downhill when heavy snow melts off into shingles during spring showers. At the same time, neglectfully unprotected roofs become susceptible to water seeping through cracks. It will often lead on its own accord towards mold growth and structural weakening due to the wood base rotting away even though the shingles might still be in good condition.
Roof underlayment is a layer of protection that goes on top of your existing sheathing and adds an extra layer for moisture resistance and some insulation properties depending on what type you use. At the same time, it doesn’t completely eliminate all water problems or guarantees against leaks from damage to plywood seams up there. This will drastically reduce the risk! A membrane-like EPDM rubber comes with a high-quality warranty that can offer coverage even if there are holes drilled into it by mistake–a common occurrence when installers don’t have experience working with different types of materials.
Can EPDM be Installed on Asphalt?
EPDM can be installed on asphalt if the surface is free of oil and other contaminants. The installation process will require a primer to seal any gaps in the seams for an airtight barrier against moisture. EPDM rubber protection must also have all nails or screws removed before it’s put down, not to puncture anything (a problem that results from over-driving with metal roofing material).
It should go without saying but make sure your asphalt isn’t too slippery underfoot when you’re doing this job–figure out what type of industrial matting might work best given your environment’s conditions. Drips are inevitable while pouring the liquid rubber into place. Spillages sometimes happen during installation due to irregularities in shape, and you’ll need to clean up any excess product that gets on the ground before it starts drying out.
Is it OK to Roof Over Existing Shingles?
If you roof over existing shingles, the sheathing boards must be installed properly. If not, be sure to add on an additional piece of plywood underlayment or a new layer of OSB board if they’re already in place before adding the rubber membrane layer. This will help prevent water infiltration and enhance structural stability by providing insulation and protection from ice dams.
The best way to avoid this problem is just knowing what’s involved with installing any type of roof, so you know how much work goes into laying down all those planks and boards in the first place!
How Do You Attach a New Roof to an Existing Roof?
1) Determine where the two rooftops will tie or meet. This is generally determined by whether both roofs have a similar pitch, then you’ll only require one framing type.
2)Carefully measure to decide how many trusses you need and use chalk guidelines on shingles to mark roof valleys’ centerlines that connect them at their peak point so they don’t sag when rafters are installed.
3) Install trusses at intersections of roof valleys and be sure to use high-quality screws or nails, as well as washers that are galvanized. If tempered shingles will be installed, then it is crucial to install a drip edge along the edges of where the rubber meets asphalt–this little detail can save you from having to replace your new roof too soon!
4) Fit sheeting or plywood over the trusses to cover valleys and nail them in place.
5) Finish by nailing metal flashing, OSB sheathing with a metal drip edge to connect the two roofs. Overlap new shingles and seal all seams for secure coverage. This is the final step to cover up any imperfections in your roof before adding new shingles!
Do Flat Roofs Use Shingles?
You should not shingle a flat roof, so it is vital to know the slope requirements for this type of material. The minimum pitch required for shingles is 2/12, which means that every 12 inches you go up on your roof, there will be an inch’s difference in height from one side of the ridgeline to another. You can’t use any type of shingle or other covering with less than a two-inch rise per foot as they are too small and won’t provide enough protection against weather damage. Like strong winds and stormy clouds carrying hot air with them when temperatures change during seasons such as summertime here in Texas!
It is important to note that Shingles work best on roofs with a steeper pitch that is 4/12 or more. If the shingles are placed on a roof with less than 2/12 pitch, water will pool up underneath and result in leaks, costing you thousands of dollars to fix!
Should Old Shingles be Removed?
The answer to whether or not you should lay new roof shingles over old ones is a complicated one. The process can save time and money, but it could also cause problems for your home’s overall integrity in the long run.
The weight of a square (100 sq ft) roof can be 350-450 pounds. With that amount, chances are your house was designed to handle the load with one layer in addition to snow and safety measures; installing new shingles on old will double the thickness, which is why building codes typically limit reroofs up to two layers. On some houses, if you have too many layers, it causes sagging between rafters/trusses because there isn’t enough support from below due to lack of structural integrity leading to damage or collapse!
Before deciding anything, you’re best off consulting with an experienced contractor before making any decisions on what to do next!
How to Install Rubber Roof over Shingles?
Did you know that rubber roofing can’t be applied directly over shingles? If you don’t want to do a complete tear-off of your existing shingles, there are some things to consider. When considering rubber roofing, you should consider both the weight and number of layers in your current home’s structure. If you are unsure about how many roofs there are or their combined weight, speak to a local authority for more information on this matter before applying any additional layers that may be too heavy – like an overlay atop shingle tiles.
If you’re thinking about installing a rubber roof, it’s essential to know that they must be installed with an air space between the old and new roofs. This is because adhesives cannot bond directly onto asphalt shingles–they’ll just peel off! So before proceeding, make sure there are some solid boards or polyisocyanurate in place on top of those tiles so once we start rolling out our lovely black rubber material over them all, nothing will go wrong. Follow these steps to install rubber roofs over shingles correctly:
- Shingles have got to be clean and dry. Ensure no sharp edges or debris are left on the barrier surface, especially if your choice is plywood. It’s best if this board has been lightly sanded and wiped with lint-free rags beforehand for a seamless install that doesn’t result in any dust getting trapped between boards while they’re being nailed down.
- Layout the rubber in the largest size you are comfortable working with. The small number of pieces creates a smaller amount of seams, which will help protect against water penetration as it ages by cutting down on where water can seep through.
- Once the rubber has flattened out and been applied to both sides (adhesive side touching substrate), then apply pressure for about 5 minutes to allow the adhesive time to bond properly before removing air pockets that form during this process.
- There is always overlap between adjacent pieces of membrane. Apply seam adhesive to the top piece of membrane and then secure it onto the bottom portion with a roll, making sure that there’s enough width for adequate coverage on both sides. Once your adhesive has dried off, use a silicone hand roller to push out any bubbles from under the tape by rolling over them again in an upward direction. This will keep everything sealed tight against each other and create an airtight seal where you need it most on those pesky seams! Seal even further with clear caulk applied at one or two-foot intervals along edges if needed – make sure they’re not too wide so as not to interrupt water flow beneath these areas.
